19:02
Patch autosetup to rename --debug to --autosetup-debug so we can use --debug/--enable-debug for its historical purpose. --with-debug is now an alias for --enable-debug but can be removed entirely if all scripts which have been adjusted for the autosetup build are edited to (re)use the older flag name.

14:18
Move handling of the tempstore feature flag into the OPT_FEATURE_FLAGS list and remove the CFLAGS.libsqlite3 makefile var which exists solely to account for the tempstore being tracked separately from the other feature flags. (check-in: 2df5065d user: stephan tags: trunk)

Makefile doc cleanups. No functional changes. (check-in: 64add0ac user: stephan tags: trunk)
13:47
Remove the libsqlite3.so.3 link from the installation process, as it now serves no functional purpose. We retain libsqlite3.so.0 (A) for compatibility with clients linked against legacy builds and (B) 0 is still valid as the library's ABI version. (check-in: 91bd9813 user: stephan tags: trunk)

16:21
New configuration option --dynlink-tools causes some command-line tools like sqldiff and sqlite3_analyzer to link against the libsqlite3.so system library rather than being built-in. Caution: sqlite3_analyzer requires the SQLITE_ENABLE_DBSTAT_VTAB compile-time option on its SQLite library in order to work, so do not use --dynlink-tools to build sqlite3_analyzer without it. (check-in: 314c606d user: drh tags: trunk)
16:17
Use shared-library flags, not shared-object flags, to create shared libraries. This makes no difference on Linux, but is required for Mac. (Closed-Leaf check-in: bfaa3ee7 user: drh tags: link-tools-dynamically)

If a subquery is copied and then changes are made to the copy, be sure to give the copy a unique Select.selId value so that the original will not be substituted in place of the modified copy. (check-in: 16d46e11 user: drh tags: branch-3.47)
14:59
Bug fix in the SubrtnSig logic from [c9a3498113074bbc], if a subquery is copied and then changes are made to the copy, be sure to give the copy a unique Select.selId value so that the original will not be substituted in place of the modified copy.

Move the in-comment-code commentary about --with-debug, from [7b14309be4], into the --help text for that flag, where it's readily visible. (check-in: c938e5d7 user: stephan tags: link-tools-dynamically)
19:47
Get sqlite3_analyzer optionally linking against libsqlite3.so instead of embedding sqlite3.c. Patch mkccode.tcl to accept digits in its IFDEF/IFNDEF checks and sqlite3_analyzer.c.in to only include sqlite3.c if -DINCLUDE_SQLITE3_C is passed to mkccode.tcl. (check-in: 80f3bf8c user: stephan tags: link-tools-dynamically)
19:16
Merge trunk into this branch. Fix a small jimtcl/tclsh regex incompatibility in mkccode.tcl. (check-in: 7fb3ebfe user: stephan tags: link-tools-dynamically)
18:26
Enhancements to tool/mkccode.tcl such that it recognizes -D command line arguments and can use them in internal IFDEF and IFNDEF macros. Update the tool/sqlite3_analyzer.c.in script such that it omits the SQLite amalgamation if -DSQLITE_ENABLE_DBSTAT_VTAB is defined. (check-in: 7fec2092 user: drh tags: trunk)

Revert linking the shell to the dll for reasons explained in new makefile comments. Move the --with-debug configure flag into the developer options set and add commentary about why it should never be used for production builds. (check-in: 7b14309b user: stephan tags: link-tools-dynamically)
17:32
Extra logging for the freelist and hash table components of COMMITs of BEGIN CONCURRENT transactions. (check-in: 2ba41da8 user: dan tags: cf8f1552-commit-instr)
16:40
Reformulate sqldiff deps and rules so that the target matches the resulting file name, to avoid rebuilding it on every make invocation. Apply the same treatment to the sqlite3 CLI shell. (check-in: 9a17b83f user: stephan tags: link-tools-dynamically)
15:20
Initial configure support for linking certain binaries to libsqlite3.so instead of embedding it dynamically (which they typically do). This currently applies only to sqldiff, but support for adding the same for other tools is planned. This requires disabling the soname because setting it causes the build to link to whatever libsqlite3.so.0 is installed system-wide, so the soname now defaults to off. (check-in: 9192c146 user: stephan tags: link-tools-dynamically)

Adjust the behavior of sqlite3_changes64() so that it counts INSERTs into a new table created using "CREATE TABLE name AS SELECT ...". It has never done this before. The documentation is a little ambiguous about whether or not it actually should. This check-in is on a branch because it will probably never make it to trunk for fear of breaking some legacy program.

More closely emulate the legacy build's handling of LDFLAGS, permitting them to be passed to configure but not to make. We cannot 100% enforce that because main.mk is not filtered by the configure script, so we instead add a level of indirection to make passing of LDFLAGS=... to make a no-op.

06:22
Support clients passing in LDFLAGS to configure/make, but in a more limited form than the legacy build it (i.e. only to select targets rather than all targets).

Disable setting of the SONAME (enabled by [2a2419ef742]), as it's not clear whether blindly setting the SONAME, which now differs from its historical value, will cause more grief than it solves. Add a (disabled) experiment which permits setting (or not) the SONAME to the legacy or current values.

Change default CFLAGS to {-g -O2} to match the legacy build. (check-in: 51177494 user: stephan tags: trunk)
01:51
Fix a corner case in automatic TCLLIBDIR detection: if the $auto_path list is not empty but none of them refer to an existing dir, the last dir in that list would have been accepted as the TCLLIBDIR. It will now error out instead. (check-in: 1d2ecae1 user: stephan tags: trunk)
00:56
Reimplement how the TCL-related environment vars are made available to make recipes which need them, reducing the console noise and consolidating it with the has_tclconfig flag file. It now uses a generated shell snippet which it sources, rather than inlining all of that shell code. (check-in: 0cdfd142 user: stephan tags: trunk)

Minor cleanups to the linenoise flavor detection test. (check-in: 3be32de1 user: stephan tags: trunk)
22:49
Move the linenoise flavor check from auto.def to proj.tcl for re-use in downstream projects. (check-in: 84e503dc user: stephan tags: trunk)
22:41
Expand [c0048e4482e9] to determine the linenoise API flavor via a compile test rather than guessing based on the filename. (check-in: dbf00791 user: stephan tags: trunk)
22:09
proj.tcl/main.mk doc updates. No functional changes. (check-in: e06574c6 user: stephan tags: trunk)

Adjust Makefile.in to honor the CC environment variable. Add the "show-variables" target to main.mk, for debugging. (check-in: e5f1a01f user: drh tags: trunk)
18:24
Add extra logging to analyze COMMIT commands. (check-in: 7dbb43bd user: dan tags: cf8f1552-commit-instr)

Merge the readonly-ignore-wal-jrnl feature into a sub-branch of reuse-schema. (check-in: 67087fe4 user: drh tags: reuse-schema-ro-waljrnl)
14:03
Fix the CLI so that it can use either the canonical Antirez linenoise (with HAVE_LINENOISE=1) or Steve Bennett's enhanced linenoise that works on the Win32 console as well as on Unix (with HAVE_LINENOISE=2). The ./configure script detects which one to use and sets HAVE_LINENOISE accordingly. (check-in: c0048e44 user: drh tags: trunk)
13:47
Require the SQLITE_ENABLE_READONLY_WALJOURNAL pre-processor macro to activate the new feature on this branch. (check-in: 21ed4e78 user: dan tags: readonly-ignore-wal-jrnl)

Fix a problem that could occur if a read-only connection switches its journal mode from "persist" to "off" or "memory" when the file-system contains a hot-journal created by a "PRAGMA journal_mode = wal" command. (check-in: 85b5ed02 user: dan tags: readonly-ignore-wal-jrnl)
05:07
Clean up and add docs to the TCL vetting steps. Make warning and error messages bold if stdout isatty. (check-in: 47157dcf user: stephan tags: trunk)
04:07
Remove accommodation of the legacy-named shared libraries from the installation rules, per discussion. Rename install-includes to install-headers. Quote installation target dir names "just in case". (check-in: 80584e16 user: stephan tags: trunk)
03:51
Generic makefile cleanups. (check-in: 6f86ff2e user: stephan tags: trunk)
02:06
Re-enable exporting of TCLLIBDIR at configure-time so that clients can override it once there rather than having to override it on an arbitrary number of make invocations (which they can still do, but now need not). Based on feedback in forum post 38f6988e57b. (check-in: ee6e15f1 user: stephan tags: trunk)
01:47
When calculating the TCLLIBDIR in main.mk, allow the user to override it using an environment var or make var assignment, per feedback in forum post 38f6988e57b. (check-in: 83863318 user: stephan tags: trunk)
00:35
Replace 3 instances of the == 'test' shell command operator with =, as == is apparently not as portable across shells. Problem reported in forum post 14274389fb2. (check-in: 68199c40 user: stephan tags: branch-3.47)
2024-10-29
23:42
Split the core-most CFLAGS, which should not be overridable (like -fPIC), into CFLAGS.core, so that went CFLAGS=... is passed on in a make invocation the -fPIC flag is not lost (as reported in forum post 39f8c543). (check-in: f5899d22 user: stephan tags: trunk)
23:19
Try to detect if --with-readline-cflags is passed a non-cflags value, e.g. readline/readline.h, and fail loudly if it is. The legacy configure accepted that formulation but silently did nothing useful with it and that formulation now causes the auto-completion test to fail, as reported in forum post f13b8e8f38402367. (check-in: c97f34d0 user: stephan tags: trunk)
20:27
General auto.def cleanups and docs. (check-in: e2f41c25 user: stephan tags: trunk)

Reformulate the readline completion signature compatibility test so that -Wunused-variable in the CFLAGS does not cause it to fail. Problem reported via email. (check-in: 3891669a user: stephan tags: trunk)
18:50
Rename an almost-name-colliding auto.def function. Fix a refactoring-induced change which broke implicit lookup of tclConfig.sh. Add msg-debug proc to enable toggling of developer-level debug messages via a configure argument. (check-in: 265ba15d user: stephan tags: trunk)

When either --readline or --editline are explicitly provided but the corresponding feature is not found, fail fatally. If not explicitly requested, simply disable that feature if the lib is not found. (check-in: 1d24a29c user: stephan tags: trunk)
08:18
Minor --help text tweak. (check-in: 80ac10ed user: stephan tags: trunk)
08:14
Add proj-assert proc and add a couple of asserts to the editline/readline checks. (check-in: db9870ca user: stephan tags: trunk)
08:01
Teach configure --editline to report itself to shell.c as either HAVE_EDITLINE or HAVE_READLINE, depending on which headers are available (editline/readline.h or readline/readline.h, both of which work and some systems only have the latter), but then link against libedit regardless of which one shell.c thinks it is using. (check-in: 85077b20 user: stephan tags: trunk)
04:21
Remove LDFLAGS_LIBZ from sqlite3.pc.in (pkg-config) because it's not needed by the library, only the shell. Re-enable the notice about --disable-static only being partially true. (check-in: e03c564a user: stephan tags: trunk)
03:29
Remove some dead auto.def code. Link tclsqlite3 shell against the .so instead of .a, analog to [45315f8f275d]. Move some header file tests which are only needed for jimsh into the jimsh compilability check block. (check-in: 9a259026 user: stephan tags: trunk)
2024-10-28
22:35
Enclose the generated "sqlite3.c" and "sqlite3.h" in a single big #ifdef so that if they get truncated by more than a little whitespace, they will not compile and the truncation can be easily detected. (check-in: c3b624e2 user: drh tags: trunk)

Minor makefile formatting cleanups. No functional changes. (check-in: 10b2cfdc user: stephan tags: trunk)

Perform some makefile acrobatics to get the tclConfig.sh state applied for static makefiles. (check-in: 9b141d10 user: stephan tags: trunk)
16:31
The async extension was superseded by WAL mode about 11 years ago, and has long been deprecated. Remove it from the source tree. (Anybody who really needs it can still dig it out of the historical records.) (check-in: f98da150 user: drh tags: trunk)
16:28
Have sqlite3_rsync avoid write-locking the origin database. (check-in: b7eb6530 user: dan tags: trunk)

Link libtclsqlite3.so to libsqlite3.so, not libsqlite3.a. (check-in: 45315f8f user: stephan tags: trunk)
14:16
Rename the 'hwaci' auto.def utility API to the more generic 'proj' API, per /chat discussion. Fix a function name typo which caused readline detection to kill the configure in one code path. (check-in: e20610f0 user: stephan tags: trunk)

02:46
Correct the default config value for HAVE_TCL (0 until proven otherwise) and fix the starting dir for SQLITE_AUTORECONFIG (formerly SQLITE_AUTOREMAKE), as reported in forum post 8ab69387008f2f6c. (check-in: 55f78b63 user: stephan tags: trunk)
02:11
Have --enable-editline fail rather than emit a warning which would easily be overlooked by automated builds. The error message explains a potential workaround for activating libedit. (check-in: 2bd1b955 user: stephan tags: trunk)

Expand the 'make help' target and clean up some overly-noisy configure output. (check-in: c895766e user: stephan tags: trunk)
22:18
Re-order the auto.def flags logical groups. Add some discrete bold formatting to select configure output. Remove some dead code. Account for behavior misunderstanding of user-notice. Add the start of a 'make help' target. General cosmetic cleanups. (check-in: ab95ee33 user: stephan tags: trunk)

Generic cleanups in auto.def and hwaci-common.tcl. (check-in: 428e5424 user: stephan tags: trunk)
20:14
Doc additions and minor cleanups in the --flag alias handling. (check-in: 37a1da03 user: stephan tags: trunk)
20:04
Rename --with-readline-lib/inc to --with-readline-ldflags/cflags, for clarity, but retain the older names as aliases using autosetup's "hidden alias" feature. Rename the newly-added --with-icu-lib to --with-icu-ldflags (with no backwards compatibility). (check-in: e50a03f9 user: stephan tags: trunk)
19:26
When ICU is enabled, ensure that the CLI shell build enables its feature flag and include LDFLAGS_ICU in sqlite3.pc. (check-in: abec913c user: stephan tags: trunk)
19:22
Add --with-icu-inc=CFLAGS, but its justification (based on examination of a downstream build script) as iffy, so this needs to be considered more closely before committing to it. (Edit: no, we don't want to pass on any ICU-side CFLAGS when building the library, especially not the one provided by icu-config --clflags.) (Closed-Leaf check-in: 5fc0b460 user: stephan tags: configure-with-icu-inc)

When readline is enabled, attempt to determine whether the completion API is compatible and, if it's not, disable it in the shell app. (check-in: 4564dbe4 user: stephan tags: trunk)

Help systems still using Tcl8.6 to compile tclsqlite.c by changing a typedef into a #define. (check-in: 82ab8ff3 user: drh tags: trunk)
09:28
Remove some incorrect code comments. (check-in: 6dfda7f5 user: stephan tags: trunk)
08:52
Re-add the --disable-static flag to (mostly) disable static lib build. Some components require the static lib and will trump this preference if they are activated. Delete temp files created by mksqlite3h.tcl. (check-in: e296cd11 user: stephan tags: trunk)
08:29
Generic auto.def cleanups. (check-in: 19a5377e user: stephan tags: trunk)

Ensure that --disable-tcl is honored. Move LDFLAGS.icu from the CLI shell target to LDFLAGS.libsqlite3. (check-in: 39ce3f63 user: stephan tags: trunk)

configure: add --with-icu-lib=LDFLAGS and --enable-icu-collations. Fix auto-reconfigure when flags contain spaces. (check-in: 2a881a2e user: stephan tags: trunk)
06:03
Makefile.in: include CPPFLAGS in the CFLAGS, as the legacy Makefile.in did, because some downstream scripts rely on that. Remove a duplicated TCLLIBDIR assignment. (check-in: 8e352f41 user: stephan tags: trunk)
05:28
configure: document why --enable-editline does not work and emit a warning with a potential alternative/workaround if it's used. Various cosmetic cleanups. (check-in: ccb8f16f user: stephan tags: trunk)
04:27
Bring the automated readline detection up to parity with the legacy configure script. (check-in: 2ddeb7a8 user: stephan tags: trunk)
02:27
Rename --with-readline-ldflags/cflags to --with-readline-lib/inc because it turns out that ldflags/cflags have (when passed an explicit value) the same semantics the legacy lib/inc flags. Still to-fix is that the no-flag-given readline search behavior differs, and is much more limited, from the legacy configure behavior. (check-in: 8f6897b9 user: stephan tags: trunk)
02:08
Correct sqlite3.pc to represent the library, not the CLI shell. Remove the half-baked an unused READLINE_H config define. Internal tcl doc fixes. (check-in: c8c70353 user: stephan tags: trunk)

Get --with-linenoise=DIR configure flag working. (check-in: 66ce47e5 user: stephan tags: trunk)
19:16
Remove the install-lib makefile dep from install-tcl, as it breaks non-root-user invocations of 'make install-tcl' when the --prefix is left at its default and --with-tcl is explicitly provided. (check-in: e7eabfb6 user: stephan tags: trunk)
18:34
configure flag --disable-readline now trumps --with-readline-... (check-in: b66076e5 user: stephan tags: trunk)

Remove LDFLAGS_ZLIB from sqlite3.pc.in because -lsqlite3 already includes that. (check-in: 47e50fa8 user: stephan tags: trunk)
16:03
Patch bundle accumulated via /chat: add missing --enable/disable-shared flag to configure script and update testrunner.tcl for other configure script flag changes. (check-in: 32fc9c3f user: stephan tags: trunk)

03:19
Expand the libtool-style link support from [0a50e33051] such that if INSTALL_SO_086_LINKS=1 is passed to 'make install' then the libtool-style names are always linked in, regardless of whether they already existed or not. In either case, we unconditionally remove libsqlite3.la because it cannot work with the newly-installed non-libtool .so file. (check-in: 2b2ca7de user: stephan tags: trunk)
03:05
Disable generation of config.defines.json until/unless it proves interesting. Honor the --disable-largefile flag. When installing libsqlite3.so and an older-style libtool installation is found, re-link the libtool-generated files to the newly-installed ones to retain their historical names. (check-in: 0a50e330 user: stephan tags: trunk)

Fix BUILD_CFLAGS (for B.cc) to not inherit CFLAGS (which are only for T.cc). (check-in: ffdce13d user: stephan tags: trunk)
23:03
Experimentally: when ./configure CC=foo is used in a non-cross-compilation build and CC_FOR_BUILD is not explicitly provided, force CC_FOR_BUILD to default to CC. This is debatable - see the code comments for the justification. (check-in: a49bee68 user: stephan tags: trunk)

Update the compile-for-*.md documents. (check-in: c4da7fa2 user: drh tags: trunk)
14:39
Rework the configure+make system to use autosetup rather than autoconf. Autosetup runs faster and is easier to maintain, and it allows for common targets (such as "sqlite3" and "sqlite3.c") to be built within having to install "tclsh". (check-in: d8c0e018 user: drh tags: trunk)
14:36
Restore the amalgamation-tarball and snapshot-tarball targets, at least for now. (Closed-Leaf check-in: 1baf4b94 user: drh tags: autosetup)

Rename config-defines.json to config.defines.json for consistent with other generated config.* files. Rename --defs-json-include-lowercase to the even less wieldy --defines-json-include-lowercase. (check-in: 131a2a7e user: stephan tags: autosetup)
04:39
Add --defs-json-include-lowercase configure flag to cause config-defs.json to include lower-case defines, which are primarily the various build-related system paths. (check-in: 0f2555ea user: stephan tags: autosetup)
04:16
Internal cleanups and docs in hwaci-common.tcl. (check-in: 30699b57 user: stephan tags: autosetup)
03:56
Docs related to the -array defs-dump option. Rename some internal-use hwaci-common.tcl APIs after discovering that a - as a symbol suffix fails for var derefs (but works for procs calls). (check-in: 0d5da388 user: stephan tags: autosetup)
03:35
Experimentally add the -array formatting option to hwaci-dump-defs-json and emit OPT_FEATURE_FLAGS/OPT_SHELL in both flat string and array forms. (check-in: ce6bc460 user: stephan tags: autosetup)
03:18
./configure now emits config-defs.json, a JSON-formatted counterpart of the DEFS=... info which the pre-built autotools bundles emit. (check-in: 800b083c user: stephan tags: autosetup)

Fix the new tool/cp.tcl so that it works with older TCL versions, such as jimtcl. (check-in: 61f18c96 user: drh tags: autosetup)
15:36
Fix harmless compiler warnings. One of the warnings was code that deliberately committed memory errors to test the systems ability to cope. But compilers don't allow that any more, so we'll have to leave that capability untested. (check-in: 7e7b3b2e user: drh tags: autosetup)
15:14
Add the tool/cp.tcl script and use it to simplify Makefile.msc. (check-in: b7db2146 user: drh tags: autosetup)
14:33
Back out [bd66222721] because it causes conflicts with test runs, apparently due to .o files being built with different flags. This means that the CLI shell currently does not honor --disable-amalgamation. (check-in: b0633173 user: stephan tags: autosetup)

Tweaks to help make jimsh0 usable to build using nmake. Does not quite work yet, but getting closer. (check-in: e911303b user: drh tags: autosetup)

07:31
Various build cleanups centered around straightening out various uses of CFLAGS and its cousins. Teach Makefile.linux-generic to figure out the TOP dir on its own (a GNU Make-ism, but it's a Linux-specific makefile). (check-in: 58a0f7e7 user: stephan tags: autosetup)
05:33
More potentially-controversial makefile symbol renaming. This is simply more readable to my eyes. (check-in: 6d4d1d5f user: stephan tags: autosetup)
05:03
Bump version number to 3.48.0 (in this branch only - in trunk, doing so requires a specific autoconf version) and rename the RELEASE and VERSION makefile symbols for clarity's sake. (check-in: 4193d90f user: stephan tags: autosetup)

03:50
Get Makefile.linux-generic (formerly Makefile.linux-gcc) working with jimsh in out-of-tree builds. Pass on -DHAVE_READLINE=1 to the sqlite3 shell if configure detects it. (check-in: a555ff6d user: stephan tags: autosetup)
03:14
General make cleanups. Start adding a sanity-check mechanism to main.mk which does basic validation of the vars it expects to be set by the file which includes it. Get Makefile.linux-gcc working for the core-most rules. (check-in: 85b2c73c user: stephan tags: autosetup)

16:46
After compiling jimsh, run sanity tests on it to ensure that it is built with -DJIM_COMPAT and one of (-DHAVE_REALPATH, -DHAVE__FULLPATH). (check-in: ea6a14a6 user: stephan tags: autosetup)
16:03
Work around a minor JimTCL regexp incompatibility in tool/vdbe-compress.tcl. Summary: it thinks that backslash-escaped octal values are back-references, which it does not like. (check-in: aeac2335 user: stephan tags: autosetup)

10:36
Add two new #include statements to the composite "fts5.c" file that is constructed as part of the build process. These #includes are no-ops in the SQLite amalgamation (and are commented out automatically by the amalgamation builder) but are needed if the FTS5 extension is built separately, it seems. Enhancement request. (check-in: 1bf8daeb user: drh tags: trunk)

01:33
Fix /dev/null and stderr redirection ordering in autosetup/autosetup-find-tclsh so that the extraneous strlcpy()/snprintf()/rand() warning output from ld on OpenBSD does not break detection of jimsh0. (check-in: cd447e50 user: stephan tags: autosetup)

Add the SQLITE_IOCAP_SUBPAGE_READ bit to the possible returns values from xDeviceCharacteristics method of the system-IO abstract class. The direct-overflow-read optimization is disabled for any VFS that does not set this bit. The bit is set for standard VFSes. (check-in: 6e7d498c user: drh tags: trunk)

03:56
After discussing [4d4423df8d14] with Steve Bennett, do not prepend $prefix/bin to the search path for binaries, as that path is commonly used for cross-compiled targets and we want binaries which will run on the build host. (check-in: f2008a7d user: stephan tags: autosetup)
03:33
Touch configure-generated files at configure-time even if autosetup does not update them because their contents would not be changed. Works around wonky deps causing too-frequent rebuilds. (check-in: 339b48af user: stephan tags: autosetup)
03:12
Rename hwaci-error to the more descriptive hwaci-fatal. Use autosetup's file-isexec instead of [file executable] for portability. Remove the binary file lookup cache - unnecessary complexity. When searching for tools like tclsh, check under $prefix/bin before checking the $PATH. This seems like the right thing to do, but the fact that autosetup's file-search API's do not do that by default leaves some room for doubt about the wisdom of this change.

Factor out all autosetup-processed @if/@else blocks from Makefile.in in prep for moving most of the makefile code into main.mk (which has, so far, been completely overlooked in this port but will now become the main basis for the static parts of the build).

Additional improvements to the behavior of ".crnl" in the CLI. The default output mode is O_BINARY so that results are identical on Windows and non-Windows systems. On Windows you can optionally do ".crnl on" to enable NL-to-CRLF conversion on output. Output to Windows console is always O_U8TEXT and so is unaffected by the .crnl setting.

Modify the behavior of sqlite_dbpage so that the null-INSERT that truncates a database must be the very last INSERT operation within a transaction in order to be effective. This simplifies the code and also makes the behavior easier to document and understand. (check-in: b869a7d9 user: drh tags: trunk)
17:43
Fix a typo in fts5delete.test. (check-in: b1f00143 user: dan tags: trunk)
17:04
Add the contentless_unindexed=1 option to fts5. This causes the values of any UNINDEXED columns of a contentless fts5 table to be stored persistently in the database. (check-in: 58313ac5 user: dan tags: trunk)
16:55
Adjust the new truncation behavior of sqlite_dbpage(N,null) such that it causes the database to be truncated to N-1 pages. This makes more since. An error is raised if N is less than 2. (check-in: 7d5ff86e user: drh tags: trunk)
13:26
Remove all use of the "long double" data type from SQLite, as hardware support for long double is increasingly rare and the use of long double creates challenges for some compilers. (check-in: 761d8fd1 user: drh tags: trunk)

16:55
Add compile-time option -DSQLITE_USE_LONG_DOUBLE=0 to omit all attempts to use "long double". Or =1 to omit attempts to use the Dekker algorithms to achieve high-resolution floating point. (check-in: ca5964ef user: drh tags: trunk)

14:09
Do not remove *.def in the cleanup rules because auto.def is a required part of autosetup. Remove the .o vs .obj detection/distinction because the Unix-like Windows environments use .o. (check-in: 65eb1072 user: stephan tags: autosetup)
13:12
Clarification of the meaning of the nByte parameter to sqlite3_prepare(). Comment and documentation change only - no changes to the code. (check-in: 92d71eee user: drh tags: trunk)
12:16
Cleanups of the --with-wasi-sdk bits. Straighten out VERSION vs RELEASE. (check-in: 7638f3ad user: stephan tags: autosetup)

Merge current trunk into this branch. (check-in: 683a9e1e user: stephan tags: autosetup)
08:25
Remove a misled acrobatics related to cross-compilation, based on suggestions from Steve Bennett. Add a quick-n-dirty placeholder check for tclsh to move that part along. (check-in: c4191689 user: stephan tags: autosetup)
01:29
Fix shell test cases to account for recent additions to the ".help" output. (check-in: 54c22bc6 user: drh tags: cli-stdlib)

23:09
Time for a break. (check-in: 1d29cd90 user: stephan tags: autosetup)
22:13
Integrate the configure-time Emscripten bits. (check-in: 456125a1 user: stephan tags: autosetup)

Change the way tokendata indexes are collected for prefix queries. (check-in: 204ddf4e user: dan tags: fts5-tokendata-prefix)
18:03
Further streamlining of auto.def. (check-in: 74d12433 user: stephan tags: autosetup)

Always show HTML table headers in ".www" output mode. (check-in: 660ca5ce user: drh tags: cli-stdlib)
15:55
Add the --plain option to the ".www" dot-command. (check-in: a9209519 user: drh tags: cli-stdlib)
15:26
Have the zipfile and fileio extensions use sqlite3_stdio.c when it is available - such as when those extensions are preloaded into the CLI. (check-in: 74bbb2b2 user: drh tags: cli-stdlib)
14:58
Improve common feature flag handling a bit. (check-in: 8716c35e user: stephan tags: autosetup)

Lots of work on auto.def and the utility tcl lib. Still lots more to do. (check-in: 2141527a user: stephan tags: autosetup)
14:09
Redirect timer output just like any other text. (check-in: 3b5ae210 user: drh tags: cli-stdlib)
13:56
Improvements to ".www" and ".output -w" so that text that is not part of query output is shown using <pre>. (check-in: f8ef65c5 user: drh tags: cli-stdlib)
13:29
Add the "www" output mode that include <table> in the HTML output. Add the ".www" command and the "-w" option to ".once". (check-in: b06fd9e6 user: drh tags: cli-stdlib)
12:56
Always include a UTF-8 BOM at the beginning of the output CSV when using the ".excel" command on Windows, as the actual Excel program requires the BOM in order to work correctly. (check-in: 04727fc0 user: drh tags: cli-stdlib)
12:16
Change --enable-tempstore to --with-tempstore to avoid the uphill (and losing) battle with autosetup's built-in handling of the --enable/--disable prefixes. (check-in: 8bea45fb user: stephan tags: autosetup)
12:03
Prevent regular DELETE and UPDATE statements from running against contentless_unindexed=1 tables that are not also contentless_delete=1. (check-in: 21539e9d user: dan tags: fts5-contentless-unindexed)
11:38
Fix stray fputs() calls in the CLI. (check-in: 1ee3fa0f user: drh tags: cli-stdlib)

09:43
Merge trunk enhancements, and especially the zero- and double-width character processing for columnar outputs into the cli-stdlib branch. (check-in: d6262a4b user: drh tags: cli-stdlib)
09:39
In the CLI, for columnar output formats, try to account for the presence of zero-width and double-width characters in the output and adjust column widths accordingly. (check-in: 9592b9ba user: drh tags: trunk)
09:33
Improvements to comments on data structures and subroutines. (Closed-Leaf check-in: b217e300 user: drh tags: variable-width-char)
08:04
Baby steps towards a working auto.def. (check-in: c223dbb4 user: stephan tags: autosetup)
07:30
Add --enable-tempstore support and document some of the weirdness of trying to use an explicit prefix of --enable with non-boolean flags (autosetup unconditionally handles --enable and --disable prefixes on its own and always treats them as boolean flags). (check-in: fe6fa4ce user: stephan tags: autosetup)
06:25
Re-enable the --enable-all bits after figuring out that autosetup(options) is not a dict, but a list. (check-in: beb2a120 user: stephan tags: autosetup)
06:07
Disable with --enable-all bits, as the helper function it uses is dying for reasons beyond my meager tcl-fu. (check-in: d2b88312 user: stephan tags: autosetup)
04:34
Correct some copy/paste errors in the previous checkin. (check-in: 9752768d user: stephan tags: autosetup)

Get several of the --enable/--disable configure flags working. (check-in: fd16d53d user: stephan tags: autosetup)
02:00
Testing libfossil checkin fix for inheritance of privateness. Edit: the test passed but this branch was subsequently made non-private because working with private branches is tedious. (check-in: 4b104926 user: stephan tags: autosetup)
01:39
Get skeleton auto.def running, but it doesn't really do much except some standard boilerplate stuff. (check-in: e707634c user: stephan tags: autosetup)
2024-09-24
21:54
Minor wasmfs speedtest1 build tweaks. Disable one wasmfs demo which was broken by Emscripten-side changes. (check-in: 5ccc85d8 user: stephan tags: wasm-build-rework)

Add the sqlite3_stdio.h library for Windows console I/O. (check-in: fcd0ecff user: drh tags: cli-stdlib)

2024-09-23
22:56
Typo fix in makefile comments. (check-in: a4a1287f user: stephan tags: wasm-build-rework)
21:22
wasm: replace much of the eval makefile spaghetti with equivalent code generated from a small C app. It turns out that's easier to read and write than doing the same thing from shell or tcl code, due entirely to C's lack of need for escaping dollar signs. (check-in: 5440de48 user: stephan tags: wasm-build-rework)
20:23
CLI uses only lib-c for I/O on Windows. No calls to Win32. Works on Win11, at least. Reads and writes unicode to/from the console and UTF-8 to/from files. Prototype code only - must testing and additional work required. (check-in: 5c54530d user: drh tags: cli-stdlib)
19:32
Fix a couple of problems with the sessions streaming interfaces. (check-in: 9a1fc8d3 user: dan tags: trunk)

Fix comment typo in the fileio.c extension. No changes to code. (check-in: bf2c5b36 user: drh tags: trunk)
17:38
Passing shell tests on Linux and Windows. A number of FILE* API content transfer calls are diverted to the consio library via macros. (Leaf check-in: 15465462 user: larrybr tags: win-dupe-crt-fio)
14:18
Fix flub in cfWrite(). (for Win32) (check-in: 3884ddb4 user: larrybr tags: win-dupe-crt-fio)

New assert()s to help verify union access. No logic changes. Testing and validation code only. (check-in: b7b64c53 user: drh tags: trunk)
02:08
Move non-console FILE* I/O to {Read,Write}File() on Win32. (This is a WIP. It builds but needs more testing.) (check-in: b769ed00 user: larrybr tags: win-dupe-crt-fio)

Improvements to the scope of valueFromFunction(). (check-in: a0f39419 user: drh tags: trunk)
15:52
Fix the preupdate hook so that it works when the "old.*" row has a column with a non-NULL default value that was added by ALTER TABLE ADD COLUMN after the current record was created. (check-in: 6a8c6879 user: dan tags: trunk)
15:38
Fix sqlite3-rsync so that it recognizes drive-letters on the front of pathnames in Windows, and does not misinterpret them as hostnames. (check-in: 54a3bbd5 user: drh tags: trunk)
15:02
Fix the preupdate hook so that it works when the "old.*" row has a column with a non-NULL default value that was added by ALTER TABLE ADD COLUMN after the current record was created. (Closed-Leaf check-in: 00a398cf user: dan tags: preupdate-hook-fix)

22:57
Fix harmless static analyzer warning in sqlite3-rsync. (check-in: a63e412b user: drh tags: trunk)
21:42
Add assert() statements to some of the sqlite3_bind() APIs that help human readers and static analyzers, both, reason about the code and verify that it is memory safe. (check-in: 97528788 user: drh tags: trunk)
10:36
In sqlite3-rsync, do not allow the '/' character to appear anywhere in the USER@HOST: prefix to one of the argument databases. (check-in: 6089a904 user: drh tags: trunk)

20:53
Fix a typo in an error message in sqlite3-rsync. (check-in: 3f25d6c8 user: drh tags: trunk)
14:11
Cleanup the sqlite3-rsync executable as part of "make clean" (check-in: 8c5e481b user: drh tags: trunk)
10:58
In sqlite3-rsync, open the replica database using ATTACH since the sqlite3_dbpage virtual table is technically a part of "main". This avoids locking problems. (check-in: 39c56c83 user: drh tags: trunk)
09:12
Improved error message in sqlite3-rsync if the SQL statement for ORIGIN_TXN fails. (check-in: 73bde71e user: drh tags: trunk)

11:38
Always show the -v traffic message even if there are multiple -v options. (check-in: fc05a5b7 user: drh tags: sqlite3-rsync)

16:12
Fix harmless compiler warning on Windows. (check-in: 86e0219d user: drh tags: sqlite3-rsync)
16:10
Close the db as sqlite3_analyzer exits. (See forum post, "sqlite3_analyzer not closing WAL-mode db cleanly" .) (check-in: 94ceac98 user: larrybr tags: trunk)
16:08
Changes so that the -consio sub-branch of sqlite3-rsync will compile on Win11. It compiles, but it does not work. The process just hangs. (check-in: b4eff1fd user: drh tags: sqlite3-rsync-consio)

13:53
Improved informational output from sqlite3-rsync. (check-in: e55e3e8e user: drh tags: sqlite3-rsync)
12:35
Preveious check-in was actually doing an 8-round KeccakF1600. This one corrects that to just 6 rounds. (check-in: 3c36f581 user: drh tags: sqlite3-rsync)
12:28
Change the hash algorithm from SHA1 to a 6-round KeccakF1600 with a rate of 160. This uses about 1/3rd fewer CPU cycles. (check-in: 96c7f47a user: drh tags: sqlite3-rsync)

21:33
A slight tweak to consio to enable it to build both (A) directly embedded in shell.c and (B) as a separately-compiled .c file for use with sqlite3-rsync.c. (check-in: 6ffb392f user: stephan tags: sqlite3-rsync-consio)

20:50
Convert sqlite3-rsync.c to use the ext/consio I/O library. The caveat is that it requires direct inclusion of the consio source code, making sqlite3-rsync.c no longer a standalone file. (check-in: 62a9b6fd user: stephan tags: sqlite3-rsync-consio)
18:15
Port some of the shell's CLI flag-handling code into sqlite3-rsync to make the arg handling more robust. (check-in: 53fb9b11 user: stephan tags: sqlite3-rsync)

15:36
Add a protocol version number to the first message, and give the two sides an opportunity to negotiate a suitable protocol number, for future compatibility. Send the page size as a power-of-two. (check-in: df0623aa user: drh tags: sqlite3-rsync)

12:17
Disable the debug-use-only functions sqlite3_mutex_held() and sqlite3_mutex_notheld() when compiling with TSAN in as much as those routines cause TSAN to complain. Response to https://issues.chromium.org/issues/41427446. (check-in: db702dd7 user: drh tags: trunk)
2024-09-10
22:14

Fix a test in fts3corrupt4.test that would fail if SQLITE_ENABLE_FTS5 was not defined. (check-in: 437849c8 user: dan tags: trunk)
16:19
Alternative implementation of fts5 locale=1 feature that allows blobs to be stored in indexed columns of fts5 locale=1 tables. (check-in: 55c5c119 user: dan tags: fts5-locale-alternate)

15:28
Testrunner.tcl enhancements: (1) Attempt to build the SQLite tcl extension if it is not already available. (2) testrunner target "devtest" is added as an alias for "mdevtest". (3) Try to keep summary information at the end of a test below 80-characters per line. (4) Update the Makefile.in so that the "clean" target removes the tcl extension built by item 1 above. (check-in: aa5f10f2 user: drh tags: trunk)

Store the values of any UNINDEXED columns of a contentless fts5 table persistently in the database. Warning: This currently creates a (technically) incompatible file-format for contentless fts5 tables that have UNINDEXED columns. (check-in: dcacb1a8 user: dan tags: fts5-contentless-unindexed)
17:01
Add SQLITE_USE_ONLY_WIN32 to the Default configuration for testing on Windows. Take it off of Stdcall. (Leaf check-in: 8ace3f15 user: drh tags: new-win32-test-config)
16:04
Enhance the "errors" command in testrunner.tcl so that it accepts the "-s" or "--summary" argument to see a list of failed jobs, and so that an additional argument is a GLOB pattern that restricts the output to jobs whose names match that pattern. (check-in: dcbebe30 user: drh tags: trunk)
14:15
Fix ext/consio so that it works correctly with SQLITE_USE_ONLY_WIN32. (check-in: efc6f3d7 user: drh tags: trunk)

12:07
Enhance the percentile extension to support percentile_cont() and percentile_disc(). Add support for ordered-set aggregate notation in the parser when compiling with SQLITE_ENABLE_ORDERED_SET_AGGREGATES. A new function property SQLITE_SELFORDER1 must appear on any aggregate function that wants to take advantage of the ordered-set aggregate notation. (check-in: 557bd245 user: drh tags: trunk)
11:17
Improved error messages on percentile functions. More tests cases for percentile and for ordered-set aggregates. (Leaf check-in: e1bca168 user: drh tags: ordered-set-agg)

Improved documentation of recent enhancements to the percentile extension. (check-in: 51e7b4c9 user: drh tags: ordered-set-agg)
23:27
The WITHIN GROUP (ORDER BY ...) syntax is now a compile-time option: SQLITE_ENABLE_ORDERED_SET_FUNCS. There is no increment in the code size if the option is omitted. (check-in: c9367e25 user: drh tags: ordered-set-agg)
20:24
Implement percentile_cont() and percentile_disc(). (check-in: b1a93f67 user: drh tags: ordered-set-agg)

18:35
Omit the percentile_cont() function added by [095c22e62248f8ef] (and not yet released) since its usage conflicts with the PG percentile_cont() function. (check-in: 3fe0a852 user: drh tags: trunk)

Avoid unnecessary sort operations when running one of the percentile aggregates as a window function. (check-in: 5d311536 user: drh tags: percentile-window)
15:02
Test cases added. (check-in: 25e68229 user: drh tags: percentile-window)

17:33
Do not fail the omittest if ICU libraries are not installed. (check-in: ddc55efd user: drh tags: trunk)
16:51
New makefile target: "tidy". The "tidy" target removes all build products be leaves behind test results. The "clean" target has been enhanced to do a better job. The tool/omittest.tcl script is rewritten to work on the configure-generated Makefile and to require no arguments. (check-in: e48add02 user: drh tags: trunk)
16:43
A couple of #defines so that the build work with SQLITE_OMIT_FLOATING_POINT. (Closed-Leaf check-in: be768f80 user: drh tags: makefile-improvements)
16:24
Rework the tool/omittest.tcl script so that it works with the configure-generated Makefile, and requires no arguments. Update the configure-generated Makefile with a new "tidy" target which is like "clean" except that is preserves test logs. Use "make tidy" to force everything to be recompiled from scratch without destroying logs. (check-in: 99491df1 user: drh tags: makefile-improvements)
12:10
Improvements to "make clean" on unix. (check-in: a1d775f0 user: drh tags: makefile-improvements)

19:13
Do not allow sqlite3_blob_open() to work on a any table that contains generated columns, even columns of the table which are not generated themselves, because such columns might be part of the expression of a STORED column. This restriction could be relaxed some, but that would be a lot of code for something that nobody ever uses. (check-in: 6e849471 user: drh tags: trunk)
15:54
Fix a dropped error code in fts5. (check-in: df55502e user: dan tags: trunk)
13:55
Update the README.md file to recommend running "devtest" instead of "mdevtest". (check-in: eb016f66 user: drh tags: trunk)
13:51
Maybe [7420b13238da4e6b] was not such a good idea. Restore "make test" so that it works as before - running a single-threaded test over the source tree with options specified by ./configure and similar. Instead, change the "make devtest" target so that runs the automated multi-threaded tests on a standard configuration. (check-in: dc9fee98 user: drh tags: trunk)
13:34
Minor wording change on testrunner output. (check-in: 115e6859 user: drh tags: trunk)
12:10
Update the "make test" target so that it is really just "mdevtest" with "srctree-check" and "sourcetest". (check-in: 7420b132 user: drh tags: trunk)
11:03
Further improvements to the status display in order to maximum the amount of information shown on the limited screen realestate available when running via "watch" or in continuous monitoring mode. All details are still shown when doing a stand-alone "status". (check-in: 557a2c65 user: drh tags: trunk)
10:36
Only limit the number of failures reported by testrunner status if using VT100 cursor movement. For a straight-up "status" command, show everything. (check-in: 791237e0 user: drh tags: trunk)
10:25
In the testrunner status display, limit the number of reported failed jobs to avoid overflowing the terminal when there are many failures. (check-in: ffeaa4d5 user: drh tags: trunk)
09:47
Disable shell test cases that require virtual tables when testfixture is built using SQLITE_OMIT_VIRTUALTABLE. (check-in: 8c73d54f user: drh tags: trunk)
09:31
Reenable SQLITE_OMIT_VIRTUALTABLE on the Device-One alignment for testrunner. (check-in: 8f2cb357 user: drh tags: trunk)
2024-08-27
22:28
Changes to the way "release" tests were constructed in [d03d35eebaf82709] were incorrect. Fixed here. Also enhance --explain to chose permutation configurations and so that PATTERNS on the the command line can match against permutation configurations. (check-in: 1f962ffc user: drh tags: trunk)
21:44
Improvements to --status overwrite in testrunner. (check-in: 26372762 user: drh tags: trunk)

19:49
Further minor improvements and tweaks to the testrunner --status display. (check-in: 7d1ccc6d user: drh tags: trunk)
19:48
Fix typo in the previous check-in. Ensure that --status header lines do not overflow and wrap. (Closed-Leaf check-in: 2eaea674 user: drh tags: testrunner-fix)
19:43
In testrunner, when doing the --status updates to the screen, be sure to overwrite dead text at the end of each line with spaces. (check-in: 7c195f13 user: drh tags: testrunner-fix)
19:28
Further improvement to the status display in testrunner.tcl. Show the number of errors and the number of test cases on the status summary. (check-in: dbc1ac86 user: drh tags: trunk)
19:27
Modify the implementation of "wrapper" tokenizers to make them more robust in the case where the database connection is closed before the tokenizers are deleted. (check-in: 7c0001d6 user: dan tags: trunk)
19:17
Improvements to testrunner.tcl: Show elapse time in MM:SS or HH:MM:SS. Keep track of the total number of tests and the total number of errors and report those values on a summary line at the end. (check-in: 40b23292 user: drh tags: trunk)
18:25
Add test code to drop an fts5 table with corrupt records in its shadow tables. (check-in: ca21c942 user: dan tags: trunk)
17:38
Updates to testrunner: (1) Omit all testing of User-Auth. (2) Automatically add the "*" wildcard before and after all pattern arguments. (3) Build the sqlite3 CLI for release tests. (check-in: d03d35ee user: drh tags: trunk)
14:35
Merge the SQLITE_USE_ONLY_WIN32 flag for consio into trunk. (check-in: e9b03b08 user: drh tags: trunk)
14:25
Only avoid all C-runtime I/O if the SQLITE_USE_ONLY_WIN32 flag is defined. (check-in: 164b1e19 user: drh tags: win-dupe-crt-fio)
13:57
Merge all the latests trunk enhancements into the win-dupe-crt-fio branch. (check-in: 2d52db98 user: drh tags: win-dupe-crt-fio)
2024-08-26
23:32
Earlier error detection while processing complex aggregate queries. dbsqlfuzz 5242c2f07f4aa031aa3c80461f18e9b7619ede9b (The previous check-in on this branch really should have been this cherrypick.) (check-in: f9c6cbc1 user: drh tags: branch-3.46)
23:19
Early termination of updateAccumulators() after error detection. (check-in: faecd450 user: drh tags: branch-3.46)
19:08
Changes to documentation comments in fts5.h. (check-in: 886545a8 user: dan tags: trunk)

Randomize the name of the attached database used to do VACUUM. (check-in: 0f4e65d7 user: drh tags: trunk)
16:15
Bind the new debug parameters in fuzzinvariants.c. (check-in: 29e9bcfa user: drh tags: branch-3.46)
14:20
Remove redundant #ifdef accidentally inserted into mkkeywordhash.c. Update 2024-08-27: This branch demonstrates that FROM-first queries can be achieved by simply adding new production rules to the LALR(1) grammar. We do not wish to go down that path at this time. But we might revisit that idea in the future. For now, this branch is closed. (Closed-Leaf check-in: b08f3b74 user: drh tags: sql-pipes)
14:06
Add the AGGREGATE clause to the pipeline. (check-in: 16d32676 user: drh tags: sql-pipes)
13:20
Working better now. (check-in: 4bdcc18d user: drh tags: sql-pipes)
12:26
Reduce rules added to the grammar. Kinda works, but there are still bugs. (check-in: 3c7a5cc6 user: drh tags: sql-pipes)
02:53
Another version of the parser with a slightly richer syntax. The ghastly pipe operator is now optional, but is never required. Pipelines cannot be initiated from an arbitrary SELECT unless the arbitrary SELECT is a subquery on the initial FROM. (check-in: 8781d735 user: drh tags: sql-pipes)
00:15
Proof-of-concept grammar rules to parse Google-style "pipe" syntax for SQL, without the ghastly "|>" operator. The grammar rules are not connected to working code. They just parse the syntax. Pipelines that begin with an ordinary SELECT statement must have the keyword "INTO" (rather than the "|>" operator) separating the SELECT from the start of the pipeline, to avoid syntactic and semantic ambiguity. (check-in: 2c4bae3e user: drh tags: sql-pipes)

Merge trunk into the wasm-build-rework branch. (check-in: a1cf3095 user: stephan tags: wasm-build-rework)

Fix compiler warnings in the CLI detected by MSVC. (check-in: 23ae505c user: drh tags: trunk)
19:06
Improved help message for the --enable-test-status configuration option. Fix the build for when that option is omitted. (check-in: b404a5fe user: drh tags: trunk)
19:02
New ./configure option --enable-test-status causes testrunner.tcl to be run with the --status option for targets like mdevtest and releasetest. (check-in: 9ca8513c user: drh tags: trunk)
18:42
Remove a term from an assert() that is no longer relevant. (check-in: 8b476625 user: drh tags: trunk)

Add fts5 auxiliary function fts5_get_locale(). For querying the locale of a stored value. (check-in: 396f720f user: dan tags: trunk)
2024-08-22
18:12
Enhance the generate_series() table-valued function such that it is able to recognize equality and inequality constraints on the "value" column and optimize its operating accordingly. (check-in: d50b7848 user: drh tags: trunk)
16:22
Add the SQLITE_INDEX_SCAN_HEX bit to the sqlite3_index_info.idxFlags bitmask. When set, this bit causes the EXPLAIN QUERY PLAN output to show the idxNum value in hex rather than in decimal. This is purely a debugging aid. (check-in: 6c00e88e user: drh tags: trunk)
2024-08-21
20:25

Refactor the SrcItem object so that information about subqueries is stored in a separately allocated Subquery object. This reduces the memory requirements for SrcItem and makes the code run faster.

More work on the minimal-mode wasm build (now 603kb uncompressed). Remove the hard-coded feature-enable flags from sqlite3-wasm.c and rely on the build to provide them. Some wasm build cleanup, but attempts to completely overhaul it have been thwarted by my inability to make script-generated makefile code more legible/maintainable than the current eval spaghetti.

16:59
Only allow variables in LIMIT clauses if the LIMIT is within a LATERAL subquery and the variable resolves to another FROM clause term to the left of the subquery.

16:55
Back out the previous change on this branch. In its place: Determine the affinity of a subquery by the left-most arm of the subquery that has an affinity other than NONE. In other words, scan from left to right looking for an arm of the compound subquery with an affinity of BLOB, TEXT, INTEGER, or REAL and pick the first one found. Or stay with NONE if no arm has a defined affinity. Test cases added. (check-in: b8ec8511 user: drh tags: compound-subquery-affinity)

11:48
For sqlite3.oo1.DB JavaScript classes, bypass execution of any on-open() SQL in SEE-capable builds because it would necessarily run before the client has an opportunity to provide their decryption key, which would leave the db handle in an unusable state and cause the ctor to throw. This currently affects only the OPFS VFSes. We may want to consider extending the ctor options object to optionally accept an SEE key and apply it when opening the db.

Add comments (only, no code) to the JS sqlite3_config() bindings reminding us why SQLITE_CONFIG_ROWID_IN_VIEW is specifically not included. JNI does not need this treatment because it explicitly supports only a very small subset of config options. (check-in: 4fea3962 user: stephan tags: trunk)

Fix the fuzzinvariants.c test module so that it does not generate invariants that depend on rowid when SQLITE_ALLOW_ROWID_IN_VIEW is used, since rowid values can be unreliable in that context. (check-in: 0d711aaa user: drh tags: rowid-in-view)

First steps toward getting -DSQLITE_ALLOW_ROWID_IN_VIEW to work again. That compile-time option is untested, undocumented, and unsupported.

Attempt to use the Dekker high-precision floating point algorithm in the ext/misc/totype.c extension. This check-in should have been derived from trunk, not the exp-values-clause2 branch. But that's ok, because both trunk and the branch are the same in all aspects that relate to this check-in and this check-in is just parking the proposed enhancement for future consideration - it is not a serious proposal at this point.

In sqlite_stat1, revert the number of rows to the average, not adjusted for the maximum. Instead add "uneven=NNN" where NNN is a multiplier to apply to the average to get the maximum. "uneven" is only reported if NNN is 10 or more. Also add the "slow" argument is the maximum number of rows reported by a full equality match is so large that a table scan seems likely to be faster. (check-in: 41773fa7 user: drh tags: enhanced-stat1)

Update the documentation to the sqlite3_set_auxdata() and sqlite3_get_auxdata() routines to make it clear that they do not work as one might expect when they are called during query planning, instead of during query execution.

The u.zJContent field of JsonNode for a string or label should NOT include the quotation mark delimiters. Ever. This is an inefficiency that really ought to be fixed on trunk, but that can wait until this branch lands. (check-in: 96f545f6 user: drh tags: jsonb)

2023-09-26
21:37
Start reworking JNI methods such that they pass void pointers from Java to C instead of passing their strongly-typed wrappers, as that is reportedly significantly faster than passing the wrapper objects to C and extracting the pointers there. There are still many, many functions left to rework for this. (check-in: 66c814dd user: stephan tags: jni-ptr-passing)

The view-scan optimization was added to enhance the performance of one specific query, but it causes performance regressions on a host of others. Disable it (at least temporarily) in order to try to find an alternative way of fixing the one specific query that it was created to fix - an alternative way that does not cause performance problems for other unrelated queries.

16:45
According to forum post 9f6db917e1, older MSVC compilers are unable to convert a double directly into an unsigned long long int, but must first go through a signed long long int. Work around this by restricting the range of doubles that are converted into long long integers so that only the lower 63 bits are used.

15:30
Move the JNI per-thread cache of NativePointerHolder refs into global space. This allows better-targeted mutex locks and incidentally eliminates the lagginess and post-run hangs in Tester1's multi-thread mode (presumably caused by deadlocks). (check-in: e209f56a user: stephan tags: jni-threading)
15:19

An initial attempt at protecting the JNI global state via mutexes at the C level instead of relying on Java's synchronized keyword. It seems to work but increases the run time of the single-threaded SQLTester batch by roughly 3 times. (Correction: it was just run on a slower machine. Cursory testing suggests that runtime performance hit might be, but likely isn't, as high as 10%.) (check-in: c64e6a52 user: stephan tags: jni-threading)

Bind sqlite3_sql() and sqlite3_expanded_sql() to JNI. Start marking C-side functions which would need explicit mutex support if we remove 'synchronized' from their Java entry points (but there are many more left to mark). (check-in: c7fb32d1 user: stephan tags: jni)
17:45
Add a doc link for the new sqlite3_js_posix_create_file(). (check-in: 0d7aac45 user: stephan tags: trunk)
17:38
Add sqlite3.capi.sqlite3_js_posix_create_file() and oo1.OpfsDb.importDb() as alternatives for the newly-deprecated sqlite3_js_vfs_create_file(). (check-in: da6eaf8d user: stephan tags: trunk)
14:31
Deprecate sqlite3_js_vfs_create_file() because, it was discovered today, its out-of-scope use of the sqlite3_vfs, sqlite3_file, and sqlite3_io_methods APIs triggers unresolvable assertions in the core when built with SQLITE_DEBUG. (check-in: f3647a3a user: stephan tags: trunk)

Update test scripts specific to this branch so that they work on windows. (check-in: f0ca13ed user: dan tags: wal2)
11:12
Up until version 3.42.0, there was a bug in json_valid() such that it would return False (0) for a NULL input. That bug is fixed in 3.42.0. This check-in adds a compile-time option -DSQLITE_LEGACY_JSON_VALID that restores the old buggy behavior for applications that depend on it. (check-in: 15c2eadb user: drh tags: legacy-json-valid)
2023-08-10
21:50
Mark _all_ JNI binding funcs as synchronized so that Java can lock them and protect our global-state access. The alternative is writing a mountain of C-side code to do the same thing. (check-in: afe190a9 user: stephan tags: jni)
21:29
Work around jdk8 and jdk19 mangling the C name of sqlite3_db_config() differently. Correct the variadic arg handling of the JNI-side subset of sqlite3_db_config() options. (check-in: 746894c3 user: stephan tags: jni)

13:10
Document that auto-extensions registered via JNI will fail if they open a db (to avoid triggering an endless loop in the auto-extensions). Discover the hard way that JDKv19 creates different mangled JNI names for some functions than JDKv8. Start reformatting much of the JNI API decls in prep for making them even longer. (check-in: 99c0941f user: stephan tags: jni)
12:36
Resolve two assertions in the auto-extension JNI which were triggered via new SQLTester infrastructure. Move SQLTester's db-init SQL injection into an auto-extension. (check-in: 2952906c user: stephan tags: jni)

Make test completion status more visible at a glance on modern terminals. (check-in: a4e96c30 user: stephan tags: jni)

Generic cleanups and fixes in SQLTester. (check-in: fc5d3cc3 user: stephan tags: jni)
02:09
Change the SQLite3Jni API annotations to use SOURCE retention (used only at compile-time). (check-in: 3c3fea6b user: stephan tags: jni)
01:44
Move all of the SQLTester code into a single file, since it's only got 1 public class. Remove 'public' from many methods which don't need it. Add more documentation to it. (check-in: 2815d676 user: stephan tags: jni)
01:19
Defer static JNI-side init of SQLTester until main() is called so that its auto-extensions do not leak over to clients of the main library. (check-in: e461fdd5 user: stephan tags: jni)
01:05

Replace the SQLTester infrastructure with a line-oriented, non-regex-heavy parser. Add --column-names command. (check-in: 88863908 user: stephan tags: jni)
2023-08-09
23:47
Port the SQLTester 'v1' commands to the 'v2' evaluation bits. Still TODO is swapping out v1 with these separate impls. (check-in: 0cf57e5b user: stephan tags: jni)
22:30
Correct REQUIRED_PROPERTIES handling to not fail if there are no properties. (check-in: 7a19bef4 user: stephan tags: jni)
22:18
More for the SQLTester rework. Can read input and dispatch commands, but only --print is currently implemented. (check-in: 4fa2ad33 user: stephan tags: jni)
19:51
Initial sketches of a line-by-line parser for SQLTester to overcome its compatibility shortcomings. Far from complete. (check-in: 43534cd0 user: stephan tags: jni)
18:25
Adapt TestScript to skip REQUIRED_PROPERTIES, per [7a07863e082664da], and improve a couple of adject reasons-for-skipping messages. (check-in: f937097e user: stephan tags: jni)
17:47
Add an extra constraint to the test-script-interpreter.md spec. (check-in: 7a07863e user: drh tags: jni)
17:23
SQLTester --result command: do not double-{}-wrap error messages and do not throw on db error. (check-in: f7be20f5 user: stephan tags: jni)
17:04
Move the test command body's trim() back into the TestScript class (to simplify Command-level code) but do it after double-verbose has had the chance to emit it as-is (so that debug output is not mangled by the trim). (check-in: f15ecb68 user: stephan tags: jni)
16:56
Tweak the SQLTester --verbose and double-verbose output a bit for legibility. (check-in: 46b79afa user: stephan tags: jni)
16:29
Strip --oom commands from SQLTester input since (A) we can't currently do anything with them and (B) they can appear as body content of --testcase commands and the current parser cannot deal with that. If --verbose is provided once, emit the name and args of each command as it's run. If --verbose is used twice or more, also emit the command's body text, if any. (check-in: 0770e846 user: stephan tags: jni)
16:03
Update the definition of "special characters" for the SQLTester and correct the code to match it. (check-in: 217f6e0c user: stephan tags: jni)
15:46
Extend TestScript to be able to report why it should be skipped. Expand the test-skipping rules to account for the current spec doc. Add the {} empty-string case to the spec doc. (check-in: 4fcc8cb0 user: stephan tags: jni)
14:47
Add a test for the --null command. (check-in: 83ac815d user: stephan tags: jni)

09:56
Some minor tweaks in SQLTester in prep for larger refactoring. (check-in: 1d93f93a user: stephan tags: jni)
2023-08-08
22:10
Remove the current-statement tracking from the JNI internals because it will break down in the face of client-side mixed-mode native/java code, e.g. in cases like SQLTester. This makes tracing of sqlite3_stmt a micron slower but also reliably correct. (check-in: 4c0ec89d user: stephan tags: jni)
21:22
Adapt JNI build to be buildable with or without SQLTester. (check-in: adae7d78 user: stephan tags: jni)

Add SQLTester dup() and dup_count() UDFs. Correct arg handling of the --run command. (check-in: 0dba3073 user: stephan tags: jni)
20:41
Correct --result arg count check and add infrastructure to let us add custom C-side behavior to SQLTester via an auto extension. (check-in: bb832170 user: stephan tags: jni)
20:15
If SQLTester now treats a no-args --result as comparing against an empty string. (check-in: 49005ca5 user: stephan tags: jni)
20:02
Add glob/notglob commands to SQLTester and complete the interrupted-midway impls of the strglob() and strlike() JNI bindings. (check-in: 4ba98ec0 user: stephan tags: jni)
19:20
When SQLTester hits an unknown command, emit a warning and skip the rest of that script instead of aborting the whole run, per /chat discussion. Reduce verbosity a bit. (check-in: 3e78d22d user: stephan tags: jni)
17:36
Minor cleanups in sqlite3Int.h. By reordering some fields in the Parse object, it packs more tightly and uses less memory and less CPU to initialize. (check-in: aa6de539 user: drh tags: trunk)
16:53
Fix an issue in the amalgamation generator in which it was not correctly expanding the SQLite version in the header comment. (check-in: 293f6191 user: drh tags: trunk)
14:58
Correct the spacing output of multi-select SQL blocks for SQLTester --result. (check-in: 8d98645a user: stephan tags: jni)
14:49
Updates to the test script interpreter spec: Rather than failing immediately upon encountering an incompatibility, simply abandon the rest of that particular input file. (check-in: d2c99b96 user: drh tags: jni)
14:40
A number of baby steps for SQLTester.java. It can now handle basic --result cases. (check-in: 0404f688 user: stephan tags: jni)
14:25
Add a few words of clarification on how the SQLite Test Script Interpreter should be initialized to start each test script. (check-in: 3aa2b5a5 user: drh tags: jni)
13:05
Correct JNI sqlite3_prepare() to emit a null stmt handle when the C counterpart succeeds but results in a NULL pointer. (check-in: 94628f88 user: stephan tags: jni)
11:46
Implement the new/open/close SQLTester commands. (check-in: dc823bf0 user: stephan tags: jni)

Add a JNI-layer sqlite3.toString() for debugging. (check-in: 45669164 user: stephan tags: jni)
10:58
Bind sqlite3_strlike/strglob() to JNI. (check-in: eb5440f7 user: stephan tags: jni)
09:45
SQLTester: add print command and improve argument error reporting infrastructure. (check-in: 1b6e84f6 user: stephan tags: jni)
00:59
Add missing license header. Minor cleanups in SQLTester. (check-in: 5be50fd5 user: stephan tags: jni)

Rework SQLTester dispatching and add stub impls for several commmands. (check-in: 9e61af75 user: stephan tags: jni)
2023-08-07
23:59
Add command dispatcher to SQLTester. (check-in: e0a06931 user: stephan tags: jni)

SQLTester now ignores tests which contain constructs specified in the spec doc. (check-in: ecaeee65 user: stephan tags: jni)
22:32
SQLTester can now split a test script into a series of individual commands. (check-in: d3d1accc user: stephan tags: jni)

SQLTester can now read a script and strip it of all noise content. (check-in: 59bd3928 user: stephan tags: jni)
21:04
Initial skeleton for adding an SQL-driven test script interpreter for the JNI bindings. (check-in: 2aa8f0ed user: stephan tags: jni)
17:09
Enhance sqlite3_vtab_nochange() so that it works with "UPDATE ... FROM ..." statements. Use this to allow some updates on fts5 contentless-delete tables. (check-in: 27ff86e4 user: dan tags: trunk)
16:15
Changes so that sqlite3_vtab_nochange() works with "UPDATE ... FROM...". Use this to allow UPDATE on a contentless fts5 table if new values are supplied for all indexed columns. (Closed-Leaf check-in: 16cd2161 user: dan tags: fts5-contentless-delete)
11:18
When converting a Java exception to a db error message, use Throwable.toString() instead of getMessage() so that the exception type's name is included. More internal API renaming for consistency. (check-in: 2d44720d user: stephan tags: jni)
10:59
Lots of JNI internal API renaming, for consistency, and moving-around of utility functions. Make it safe for more callback types to throw. (check-in: 9a494394 user: stephan tags: jni)
10:01
JNI API renaming to better match the C API. (check-in: 6e0bd03d user: stephan tags: jni)
09:44
Rename fts5_api pContext parameters to pUserData, per /chat discussion. This is a cosmetic change made to reduce confusion between those parameters and the two other context-type parameters in that API. (check-in: 2ca064d8 user: stephan tags: trunk)
01:06
Make sqlite3_stmt() Java ctor private - it's only constructed from JNI code. (check-in: ce82c42f user: stephan tags: jni)
00:29
Minor internal cleanups and additional test metrics. (check-in: fa0a6b6e user: stephan tags: jni)
00:06
Bind the auto-extension APIs to JNI. (check-in: 746a5fa0 user: stephan tags: jni)
2023-08-06
22:09
Rework the sqlite3_open(_v2)() order of operations so that pending auto-extension support can get ahold of the open-time Java state despite the Java/C (sqlite3*) binding not having yet been established. (check-in: 34da294a user: stephan tags: jni)
21:29
Completely rework how the JNI sqlite3_open(_v2) and sqlite3_prepare(_vN)() bindings deal with output pointers to give the JNI side full control over the origin of db and stmt handles (necessary for solving chicken/egg situations in auto-extensions and prepare-time trace). Lots of adjacent internal API renaming. (check-in: 644999ca user: stephan tags: jni)
20:01
Start adding JNI-side support for auto extensions, but hit a brick wall which requires slightly awkward semantics changes in the JNI bindings for sqlite3_open(_v2)() to resolve, so stash this #if'd out for the time being. (check-in: 77a32d23 user: stephan tags: jni)
15:01
Doc cleanups. (check-in: 5f56b007 user: stephan tags: jni)
14:19
Bind sqlite3_config() to JNI for call variants taking (int,int*) and (int,const char *) variadic arguments. (check-in: 6119289d user: stephan tags: jni)
13:02
JNI-internal cleanups and API renaming. Add a C-side java-string-to-utf8 conversion. (check-in: 672d8579 user: stephan tags: jni)
11:05
Remove doc outdated warning about sqlite3_trace_v2() JNI binding being incompatible with MUTF-8. Use new to-string capability to simplify Fts5ExtensionApi::xColumnText() JNI binding. (check-in: ebcfc237 user: stephan tags: jni)
10:49
Add a way to convert from standard UTF-8 to a Java string (JNI lacks this capability). (check-in: 07dd082c user: stephan tags: jni)
10:14
Bind sqlite3_db_filename() and (closely related) (A) add many more docs about the UTF-8/MUTF-8 discrepancy (B) start adding internals to enable us to perform the standard-UTF-8-to-Java conversion from C. (check-in: 586720fa user: stephan tags: jni)
2023-08-05
22:41
Bind sqlite3_set_authorizer() to JNI. (check-in: e0fa0313 user: stephan tags: jni)
21:35
Refactor the per-JNIEnv cache from a fixed-size static array to a linked list of dynamically-allocated entries. Uncache all per-db state (which is necessarily JNIEnv-specific) when the corresponding JNIEnv is uncached. (check-in: 9dd8b784 user: stephan tags: jni)
20:19
Add SQLite3Jni.uncacheJniEnv(), a way for Java threads to clear their thread-specific cached state from the JNI bindings when they're about to terminate (or are otherwise done using the library). (check-in: 7468f876 user: stephan tags: jni)
19:20
In the JNI docs, note that the sizeof SQLITE_TRANSIENT and SQLITE_STATIC should ideally be the same as the platform's pointer size. (check-in: 7d4ac44e user: stephan tags: jni)
19:15
Tiny doc typo fixes from forum post 31eb707250. No code changes. (check-in: 8ede5008 user: stephan tags: trunk)
12:48
JNI internal refactoring and cleanups. (check-in: 7397973a user: stephan tags: jni)
11:16
Bind Fts5ExtensionApi::xUserData() to JNI and extend xCreateFunction() to accept that argument. In test code, use assert() instead of exceptions if assert() is enabled so that test failures (exceptions) thrown via callbacks do not get suppressed (which they otherwise necessarily are to avoid crashing the host app). (check-in: e4383737 user: stephan tags: jni)
04:30

11:06
Never flatten a CTE that is labeled MATERIALIZED. This is really something of a bug fix because the documentation says that a MATERIALIZED CTE is an optimization barrier. (check-in: b7ef9796 user: drh tags: materialize-order-by)
00:09
When a query is inside an AS MATERIALIZED CTE, do not attempt the omit-ORDER-BY optimization. If the developer specifies MATERIALIZED, that means he wants the sort to actually happen. (check-in: aa769ee7 user: drh tags: materialize-order-by)

Restrict the new column cache to table-btree, which is the common case anyhow. That way, writes to indexes do not need to clear the column cache. (check-in: 659284ab user: drh tags: trunk)
20:02
The original column-cache implementation from check-in [ab1edcc7fedcf279] (merged to trunk at [771fe35074b50b8d]) is unsound. This check-in fixes the issue. Had to give back a little performance, the optimization is still a overall win. (check-in: ec95e970 user: drh tags: trunk)

Experimentally change the JNI sqlite3_trace_v2() callback type to have more convenient access to the current Java-side sqlite3_stmt at the cost of some uncomfortably fiddly current-statement tracking in the JNI layer. Subject to change. (check-in: 459db332 user: stephan tags: jni)

A failed attempt to add a new sqlite3_result_zeroterminated() interface that is a hint to SQLite that a TEXT result does have a zero terminator. The idea is to avoid unnecessary copying of TEXT values. This seems like an unnecessary complication at the moment, but maybe I'll return to this later.

Remove the batch SQL runner from the JS build's 'all' target, as it's long-since unused and adds noticable build time. Add makefile comments about JSPI. (check-in: b8f708e3 user: stephan tags: trunk)
11:11
Add SAHPoolUtil.getFileNames() method, and tests for it, per forum feedback. Add a test to demonstrate that two SAH pools can coexist so long as they have different names. (check-in: 72dc3f8c user: stephan tags: trunk)

Merge the latest trunk fixes into the json-opt branch. (check-in: ef4e1664 user: drh tags: json-opt)
01:12
Add the concept of an RCStr string - a "Reference Counted String". Use these to keep track of big JSON strings that might need to be used in multiple places at the same time with different lifetimes. Add two different JSON string values to each parse - one with and one without changes. The net result is a large reduction in the number of parses that occur when doing an UPDATE of a indexed JSON field using json_replace() or similar. (check-in: a4c1af61 user: drh tags: json-opt)
01:05
Extend the enhancement to json_set() and json_replace(). Clean up cruft. (Closed-Leaf check-in: 2dbb22c7 user: drh tags: json-opt-rcstr)
00:48
Add the JsonParse.zAlt field to old revised JSON text after a change. Demonstrate that this elminates the need for reparsing after a change by using it in the json_remove() function. This is an incremental check-in containing lots of cruft. (check-in: f930b139 user: drh tags: json-opt-rcstr)

Clean up some #defines in json. (check-in: 327fff50 user: drh tags: json-opt)
22:34
Rework the JSON parse structure to facilitate better caching. Passes all tests. (check-in: ecdcb1de user: drh tags: json-opt)
19:13
Add the fts5 'delete-automerge' integer option. A level is eligible for auto-merging if it has a greater than or equal percentage of its entries deleted by tombstones than the 'delete-automerge' option. Default value is 10. (check-in: b314be66 user: dan tags: fts5-contentless-delete)

16:37
Do not read past the end of a text buffer looking for a zero terminator, as that space might not be initialized. If the buffer is owned, just set the null terminator. This is a better fix for the OSSFuzz-detected use-of-initialized-value problem. (check-in: 931bccb0 user: drh tags: trunk)
15:21
Fix a harmless use-of-initialized-value warning from OSSFuzz that results from recent large string optmizations. (check-in: 1a6b3dd1 user: drh tags: trunk)

12:52
Enhance the JSON parser cache such that it is able to extract lines from the cache and use them for writing, though they then have to be evicted from the cache. This was an experiment in trying to reduce the amount of parsing needed for a big UPDATE, but it does not seem to help any. Retained for reference only. (Closed-Leaf check-in: 2e6fbebc user: drh tags: json-write-cache)

Fix memory leak in fts5 introduced by [def41225]. (check-in: 4dcad2db user: dan tags: trunk)
16:24
Major restructuring of the opfs-sahpool bits to better support multiple instances per app (each sandboxed from each other). Eliminate the pesky promise resolution race condition when two such instances are loaded in parallel. (check-in: 95e5fa49 user: stephan tags: opfs-sahpool)
15:06
Experimental (untested, non-working) changes that try reduce the number of reprepares generated by sqlite3_stmt_explain(). I think I see an easier way to do this now, so I'm parking this experiment on a branch to pursue the new idea. (Closed-Leaf check-in: c2fba6a6 user: drh tags: sqlite3-stmt-explain-opt1)

14:07
speedtest1.js: only install opfs-sahpool if it's provided via --vfs flag, to avoid locking errors in concurrent speedtest1 tabs with other VFSes. Add opfs-sahpool reserveMinimumCapacity(). (check-in: aa94c8ab user: stephan tags: opfs-sahpool)
12:02
During "opfs" VFS init, check for URL param opfs-disable and, if set, do not install the VFS. Added per forum suggestion to provide a way to help rule out misinteraction between the "opfs" and "opfs-sahpool" VFSes. (check-in: 29905b7a user: stephan tags: opfs-sahpool)

opfs-sahpool VFS now seems to work, in that it runs fine (and blazingly fast) in speedtest1. Add sqlite3.config options for the high-level configurable parts of opfs-sahpool. (check-in: 5d92d5f4 user: stephan tags: opfs-sahpool)
01:02
More work on porting the sahpool bits. Revert to random backing-store names because it works better with the capacity-reduction algorithm. (check-in: b4e005fd user: stephan tags: opfs-sahpool)
2023-07-14
23:02
Switch opfs-sahpool to use deterministic backing-store file names. Delay VFS registration until after the pool's files are all opened. Fail vfs init if the client's OPFS API has an async FileSystemSyncAccessHandle.close() method (indicating that it's outdated). (check-in: 7c6697ed user: stephan tags: opfs-sahpool)

Add the SQLITE_ENABLE_NAN_INF compile-time option which makes the following behavior changes: (1) sqlite3_value_double(NULL) returns NaN, (2) SQLite preserves NaN values rather than converting them to NULL.

(4) Non-standard JSON is never generated by SQLite JSON routines, but those routines will accept floating point literals "NaN", "Inf", and "-Inf". (check-in: 96ec8306 user: drh tags: nan-inf)

Cherrypick the "(X IS [NOT] NULL)" fix from trunk onto branch-3.41. (check-in: 0fc7f7c2 user: drh tags: branch-3.41)
16:25
When it is known when preparing a statement that X cannot be NULL or is always NULL, transform the expression (X IS NULL) to integer value 1 or 0 instead of 'true' or 'false'. This is because under some circumstances, "Y IS TRUE" or "Y IS FALSE" may not be equivalent to "Y IS 1" of "Y IS 0". This problem was introduced by [de9c86c9e4cdb34f] and was reported by forum post 2cd11c2d37. (check-in: cc4bb05b user: dan tags: trunk)

Only use a Bloom filter on an automatic index if one or more of the key columns in the index can take on non-TEXT values. (check-in: 5916705c user: drh tags: trunk)
14:28
In the Bloom filter optimization, hash all strings and blobs into the same value, because we do not know if two different strings might compare equal even if they have different byte sequences, due to collating functions. Formerly, the hash of a string or blob was just its length. This could all be improved. Fix for the issue reported by forum post 0846211821. (check-in: 090304b8 user: drh tags: trunk)

17:50
If OP_Rewind has P2 of zero, that is an assertion that the table is never empty.

Add an assert() to the byte-code engine that goes off if the OP_Halt opcode is invoked with SQLITE_INTERNAL. This causes the RIGHT JOIN error "Opcode jumps to ... which is outside the subroutine ..." to fail immediately, causing it to come more readily to tester's attention.

Back out the part of the change in [88a05141c28e5ff1] that adds affinity to the materialization of a view, as the affinity can be undefined for a compound query. This passes all TCL tests, but shows failures in the TH3 tests derived from forum post 6f842bc5b2dadcb2, presumably because the WHERE clause of the query uses constraints of the form "source_crs_code='8675'" instead of "source_crs_code=8675". Perhaps further changes on this branch should reimplement affinity on joins in cases where the affinity is unambiguous. (check-in: fe5a77bc user: drh tags: refactor-subquery-types)

Further fix for ticket [57c47526c34f01e8]. If a subquery has a result set column of the form "CAST(expr AS NUMERIC)" do not give that column NUMERIC affinity. NUMERIC affinity always goes to an integer if able, but a CAST to numeric is a no-op if the input is a number. So the two are not equivalent. (check-in: f0325359 user: drh tags: trunk)
18:58
If a subquery has a result column of the form "CAST(... AS NUMERIC)" then give that column no affinity rather than NUMERIC affinity. This is because casting to numeric preserves real values that could be integers but numeric affinity does not. By using no affinity on the column, we make the behavior consistent if the subquery is implemented as a co-routine or is materialized. (Closed-Leaf check-in: ece07d09 user: drh tags: cast-to-numeric)

Revert part of [9386d6f63468] because the new automatic function pointer binding cannot properly track per-context function mappings when the context is more complex than a single context-type pointer. e.g. it is fine for sqlite3_trace_v2() but it breaks down with sqlite3_create_collation() because that one needs to use the collation name as part of the context key and we cannot sensibly do so with the current code.

Export sqlite3_result_subtype() and sqlite3_value_dup/free/subtype() to WASM. (check-in: 4600a7bb user: stephan tags: trunk)
15:12
Expose sqlite3_value_frombind/nochange/numeric_type() to WASM. Add a flag to sqlite3_value_to_js() to cause it to return undefined, instead of throwing, if no conversion can be found. (check-in: de8fc4bf user: stephan tags: trunk)
14:46
Refactor the sqlite3_value-to-JS conversion from an internal detail to sqlite3.capi.sqlite3_value_to_js() for use with routines like sqlite3_module::xFilter(). (check-in: f6dbf280 user: stephan tags: trunk)

Fix typo in the SQLITE_DBCONFIG_LOOKASIDE documentation. (check-in: c6e7582a user: drh tags: trunk)
12:12
Remove some unused sqlite3_status() codes from the JS API. Add custom JS wrappers for sqlite3_create_collation/_v2() which accept JS functions (plus tests). Expand the argument options for sqlite3_wasm_db_error() to enable it to translate exception objects to C-level errors. (check-in: 073a2f1e user: stephan tags: trunk)
09:23
Rename the oft-used, verbose sqlite3.wasm.get/setMemValue() and get/setPtrValue() to peek/poke() and peek/pokePtr(). The old names are retained as aliases just in case any client code actually uses them, but they are now deprecated. (check-in: ad0a8139 user: stephan tags: trunk)

Micro-optimization in the oft-activated JS-to-WASM arguments conversion step. (check-in: ee47e9b8 user: stephan tags: trunk)
07:17
Correct a test bug which broke the previous checkin's wasm tests in higher optimization levels. Test bug - it should not have worked in -O0 mode. (check-in: f07141b7 user: stephan tags: trunk)
05:47
Export sqlite3_status() and sqlite3_stmt_status() to wasm. Expand the arg/return semantics of wasm.get/setPtrValue() and get/setMemValue() to simplify handling of multiple pointers. Edit: tests pass when built with -O0 but fail with -Oz. Moving to branch to work out the breakage. Edit: it was a test bug - one too many levels of pointer indirection. It shouldn't have worked in low-optimization mode. (check-in: e144fd5c user: stephan tags: trunk)

Fix a (harmless) off-by-one error in code generation that comes up when doing a DISTINCT query against a virtual table with an OR term in the WHERE clause and where the ORDER BY clause has 64 or more references to the result set. Forum post dfe8084751. NB: The bug is "harmless" in the sense that no harm comes of it in a production build. However, an assertion fault might occur in a debugging build given some really wonky SQL inputs without this fix. (check-in: 04af7ef7 user: drh tags: trunk)

Minor touchups to the JS test index page and test server push rules. (check-in: 0881f3e9 user: stephan tags: trunk)
10:43
wasm builds: explicitly set a default stack size because emsdk 3.1.27 reduced it from 4MB to only 64kb, leading to memory corruption when kvvfs is used (it requires at least twice that for I/O). (check-in: 75811246 user: stephan tags: trunk)

sqlite3-wasm.c: code legibility and coding style tweaks. Increase SQLITE_DEFAULT_PAGE_SIZE from 4k to 8k, as that improves OPFS speedtest1 performance by roughly 12%. (check-in: c260895f user: stephan tags: trunk)
07:14
Expand JS tests for db export/import and document reason it cannot currently work with kvvfs. Fix a minor JS build dependencies bug. Update page title with PASS/FAIL prefix for tester1.js to improve overview when launching multiple test tabs. Add ability of tester1 should-run-test predicates to report why a given test is disabled.

Rename some OPFS JS files. Prevent JS bindings of sqlite3_uri_...() from performing JS-to-C-string argument conversion on their first argument, as doing so is specifically illegal. (check-in: 79832808 user: stephan tags: trunk)
05:27
Refactor a significant chunk of the OPFS sqlite3_vfs init code into sqlite3.VfsHelper, and internal-use-only API encapsulating code relevant to creating new VFSes in JS. Intended to assist in pending experimentation with an alternative OPFS VFS. (check-in: e25d7b08 user: stephan tags: trunk)

05:25
Internal restructuring of the OPFS sqlite3_vfs in order to facilitate certain experimentation and improve error reporting/hints if it cannot be activated. Deprecate the name sqlite3.opfs.OpfsDb, preferring sqlite3.oo1.OpfsDb for consistency with JsStorageDb and any future DB subclasses. (check-in: 0c5c51f4 user: stephan tags: trunk)
02:23
Add an explicit warning about the current API-instability of the sqlite3.opfs namespace, which may need to be eliminated based on re-thinking of how the OPFS sqlite3_vfs is registered. Comment changes only - no code. (check-in: 0cb2fd14 user: stephan tags: trunk)

OPFS VFS: add the opfs-unlock-asap=1 URI flag which tells the VFS to release implicit locks ASAP instead of during VFS idle time. This improves concurrency notably in the test app but brings a significant performance penalty in speedtest1 (roughly 4x slowdown). This is not the final word in OPFS concurrency, but gets us a step further. (check-in: 9542f9ce user: stephan tags: trunk)

18:51
Aggregates with GROUP BY now make use of expressions on indexes. This code works and gets the correct answer for the test case in the ticket. Lots more testing and documentation is needed, however. (check-in: 8dcf9f20 user: drh tags: agg-with-indexed-expr)

OPFS: if an op which needs a lock is called when no lock has been obtained, automatically lock it at the start of the op and unlock it at the end of that op. This is an attempt to alleviate the cross-tab contention described in forum post 58a377083cd24a but it increases speedtest1 run time by approximately 4x. Perhaps auto-lock can be combined with the older idle-time-based auto-unlock to unlock such locks (but not those from xLock()) to improve this?

15:38
speedtest1: use the current (or default) vfs->xDelete method to unlink the db. This is specifically necessary when running the opfs vfs in a wasm build of speedtest1. This worked without this fix until recently because the affected test code was performing similar acrobatics in its stead. (check-in: d3c830bd user: stephan tags: trunk)
13:46
Fix the ".dump" command in the CLI so that it is more rebust against corrupt database files. At the same time, enhance the sqlite3_strglob() and sqlite3_strlike() interfaces so that they will do sensible things with NULL string pointers. (check-in: 681c85ef user: drh tags: branch-3.39)
13:44
Enhance the sqlite3_strglob() and sqlite3_strlike() interfaces so that they will do sensible things with NULL string pointers. This is an extra layer of defense against bugs such as reported by forum post 730b554179. (check-in: 8ba9c884 user: drh tags: trunk)

Minor doc tweaks in the JS GNUmakefile. (check-in: 9c8df130 user: stephan tags: trunk)
08:15
Remove persistence from the 'reverse log order?' checkbox in tester1.js to eliminate an inconsistency between the main-thread and worker-thread modes (the latter having no option for persistence of that setting). (check-in: ecf906b0 user: stephan tags: trunk)
08:06
Minor cleanups and doc improvements in the OPFS sqlite3_vfs proxy. (check-in: 48645f7b user: stephan tags: trunk)

This check-in attempts to make the SrcItem object smaller by combining the zDatabase and pSchema fields into a single union. It mostly works, but there are some issues, and the performance savings is minimal. So it is side-tracked onto this dead-end branch. (Closed-Leaf check-in: 80fbb30f user: drh tags: failed-opt-attempt)
18:42
Fix typo in comment. (check-in: f65c9565 user: drh tags: trunk)

13:20
Improve the ability of the query planner to recognize covering indexes even on tables with more than 63 columns and where the index is over columns beyond the 63rd column. (check-in: f058773e user: drh tags: trunk)

2022-10-22
23:09
More frequently send the complete SELECT statement into sqlite3WhereBegin() so that it can more accurately determine index coverage. (check-in: f6d09c5a user: drh tags: covering-index-enh)
20:13
Enhance the query planner with the ability to discern when an index is covering even when it indexes columns well beyond the 63rd column. (check-in: 1390417b user: drh tags: covering-index-enh)
14:16
This branch attempts to improve the detection of covering indexes. This first check-in merely improves a parameter name to sqlite3WhereBegin() to be more descriptive of what it contains, and ensures that a subroutine is not inlines so that sqlite3WhereBegin() runs slightly faster. (check-in: cadf5f6b user: drh tags: covering-index-enh)
13:49
Clarification on the meaning of SrcList and SrcItem and especially the SrcItem.colUsed and Index.colNotIdxed fields. Comment changes only - no changes to code. (check-in: d96f6cc8 user: drh tags: trunk)
2022-10-21
20:12
Begin transitioning the fixed-length (64-bit) bitmap used to keep track of the subset of columns of a table that are used by a query into a more general structure that can work with wide tables. Experimental. (Closed-Leaf check-in: 5dd78588 user: drh tags: column-set)

Make semantics for UDF xFinal() result handling and error reporting handling more flexible. (check-in: 89f3e198 user: stephan tags: trunk)
21:28
Add more JS tests. Flesh out the aggregate UDF tests to use sqlite3_aggregate_context() so that they can each be used multiple times in the same statement. Add sqlite3_js_aggregate_context() convenience helper. (check-in: 9d034ef5 user: stephan tags: trunk)

16:12
Only enable the bMaybeNullRow flag on IndexedExpr for an index on an expression, not on a virtual column. But do enable it for the right operand of a right join. (check-in: a9657c87 user: drh tags: trunk)
13:36
The generalized indexed expression optimization of [2435112867fbd7b6] makes the prior [a47efb7c8520a011] enhancement from 2017 obsolete. This check-in removes the older optimization. (check-in: 56442c9b user: drh tags: trunk)

If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it. This is the "Indexed Expression Optimizations". (check-in: 3da10328 user: drh tags: branch-3.28)

04:44
Apply considerable acrobatics to get the JS/WASM deliverables building to and loadable from a directory other than the one which contains the app-level code. Requires an only-slightly-leaky abstraction of passing a URL argument when loading sqlite3.js but provides much greater flexibility in where the JS/WASM files are located. (check-in: 6d468dab user: stephan tags: trunk)
01:07
Considerable wasm/js build cleanups and reworking. Remove wasmfs builds from the end-user deliverables and disable the wasmfs build by default, per /chat discussion, as it doubles our deliverable count for only marginal gain. Attempt to move the sqlite3.js/wasm files into subdirectories but rediscovered that that breaks loading in Worker mode because URI resolution of the wasm files differs depending on whether the main script is loaded from a script tag or a Worker.

18:47
js: implement a hand-written wrapper for sqlite3_create_function_v2() which converts, if necessary, JS-function-type args to WASM function wrappers. Replace DB.createFunction() impl with the new one. (check-in: 435ab333 user: stephan tags: fiddle-opfs)

20:35
Add JS wrapper for sqlite3_exec() which knows how to handle a JS callback. Add some console.error() reporting of module-load failures, as they otherwise often get silently swallowed up by the loader's mechanisms. Add 'flexible-string' JS-to-WASM argument converter which performs more X-to-string conversions than the 'string' arg converter does. (check-in: 96818aa8 user: stephan tags: fiddle-opfs)

10:55
wasm: expose sqlite3_de/serialize(), sqlite3_malloc/free() and friends, noting that the former explicitly lies on use of the latter for memory management so is not generically safe for use in wasm. (check-in: fbc0edb5 user: stephan tags: fiddle-opfs)
2022-09-29
22:08
Add JS infrastructure to ostensibly allow us to customize the wasm imports, which will hypothetically allow us to eliminate the dependency on EM_JS(), but the corresponding Emscripten glue-level feature currently breaks fatally with WASMFS builds so it's disabled. (check-in: 88d9253b user: stephan tags: fiddle-opfs)
17:35

Version 3.39.4 (check-in: a29f9949 user: drh tags: release, branch-3.39, version-3.39.4)
13:17
Rework the Emscripten-emitted module loader/init function such that it passes on the sqlite3 module, instead of the Emscripten module, to the first then() of sqlite3InitModule()'s returned Promise. This eliminates any need to mention the Emscripten module object in client-side code unless they want to configure it in advance for loading-status reports.

Reformulate some JS to work around a buggy/broken code transformation in one of the Emscripten-driven code optimizers. (check-in: e1249369 user: stephan tags: fiddle-opfs)
19:51
Put pieces in place for fiddle to support opfs, but more cleanup is required in the sqlite3.js/fiddle connection. bigIntEnabled now defaults to whether the Emscripten's module has bigint enabled. Add wasm-sensible defaults for several SQLITE_ENABLE/OMIT flags in sqlite3-wasm.c. (check-in: 7c7fb753 user: stephan tags: fiddle-opfs)

12:25
Added some structure to the wasm demo link list. (check-in: 777077c4 user: stephan tags: fiddle-opfs)
09:54
The RIGHT JOIN logic added to version 3.39.0 added a new restriction on the query flattener which resulted in a performance regression for some queries, as documented by forum post 96b9e5709cf47cda. This change removes that restriction (thus restoring performance) and fixes the problem that RIGHT JOIN was having in a different way. (check-in: 501609ed user: drh tags: trunk)

Update the fuzz invariant checker to conform to the latest changes in dbsqlfuzz. (check-in: 8d8c1243 user: drh tags: trunk)
16:57
Is the query flattener restriction 29 (do not allow both EP_InnerON and EP_OuterON constraints on the same FROM clause term) really necessary? This branch explores what happens if we omit that restriction. This is an effort to address the performance regression reported by forum post 96b9e5709cf47cda that is caused by flattener restriction 29. (check-in: 19270577 user: drh tags: flattener-omit-restriction-29)

Remove extraneous result-code SAB slots. Doc additions. (check-in: 88de2071 user: stephan tags: opfs-proxy-atomics)
08:27
An alternative messaging strategy for the OPFS VFS proxy which uses only SharedArrayBuffer and Atomics, instead of worker messages, for communication (only the initial one-time handshake during initialization uses worker messages). It runs speedtest1 approx. 15-20% faster but still 20-ish% slower than WASMFS Edit: further tests showed it to be very close to the same speed as the Worker-message variant, inconsistently faster or slower within a small margin of error. The former impl is easier to understand, though. (check-in: a83ee308 user: stephan tags: opfs-proxy-atomics)

Cut the speedtest1 runtime of the OPFS VFS proxy by approximately 3/4ths via xRead/xWrite buffer-copying optimizations. Still slower than the WASMFS impl by approx. 1/5th. (check-in: fb7f2873 user: stephan tags: fiddle-opfs)
14:56
Remove an obsolete file. Update wasmfs build for today's changes. Fix the case that OPFS.xTruncate() is passed a BigInt instead of a Number. (check-in: 97605392 user: stephan tags: fiddle-opfs)
13:44
Add sqlite3_web_vfs_list() to JS API. Corrected OPFS VFS's registering itself as the default VFS. speedtest1-worker now uses the xDelete() of both the default VFS and OPFS, to avoid that it starts up with a persistent OPFS test db (the native app calls unlink(), but that unlink call operates on a different virtual filesystem than the OPFS VFS). (check-in: 2ec7e091 user: stephan tags: fiddle-opfs)
13:16
Merge kv-vfs branch into fiddle-opfs. Adjust various JS APIs and apps to deal with the new method of handling kvvfs. Adjust speedtest1 JS build to include sqlite3-api.js so that it can use kvvfs and opfs VFSes. Permit passing of the vfs as a URL parameter to certain demo/test apps. Milestone: speedtest-worker.html?vfs=opfs runs with the standalone OPFS impl. (check-in: ec09f32f user: stephan tags: fiddle-opfs)

03:05
Move the OPFS VFS bits back into api/sqlite3-api-opfs.js. Refactor the OPFS VFS init process to use a Promise-returning function which the client must call, as that eliminates any uncertainty about when the VFS (necessarily activated asynchronously) actually becomes available to the client. Rename x-sync-async.* to test-opfs-vfs.* Milestone: first successful test of OPFS without WASMFS. (check-in: b2abf60d user: stephan tags: fiddle-opfs)
02:35
Move the OPFS VFS bits back into api/sqlite3-api-opfs.js. Refactor the OPFS VFS init process to use a Promise-returning function which the client must call, as that eliminates any uncertainty about when the VFS (necessarily activated asynchronously) actually becomes available to the client.

Add batch-runner-kvvfs.html, a kvvfs-specific build of batch-runner.html. Reduce the speedtest1 --size X value for the batch list generation to 5 so that the kvvfs batch runner can handle it. (check-in: d8df2592 user: stephan tags: fiddle-opfs)
02:28
Remove --nosync flag from speedtest1-kvvfs.html, as that seems to be the trigger for the 'no such table: z1' error. That app now warns if that flag is passed to it via URL args. (check-in: ad0677e8 user: stephan tags: fiddle-opfs)

Initial build of kvvfs in wasm.

Do not allow FROM-clause terms on the left side of a RIGHT or FULL JOIN to be reordered. forum post 6650cd40b5634f35. This is probably more strict that necessary to get correct behavior, but for the first release that supports RIGHT/FULL JOIN it is perhaps better to be correct than fast.

Do not allow an ON clause to references tables to its right if there is a RIGHT or FULL join anywhere in the query.

WASM: removed the in64-related bindings, as MDN says that calling a wasm function which has an int64 type in its signature will currently throw because JS has no 64-bit integer support. Those bindings now use doubles and simply hope that the user doesn't exceed their integer precision (2^53-1, approx 9 quadrillion). (check-in: 392e8482 user: stephan tags: trunk)

22:10
WASM: an arg handling fix for DB.exec({multi:true...}). (check-in: 0d6332f7 user: stephan tags: trunk)
22:00
WASM: added exec(), execMulti(), and several getters. Various touchups and fixes. (check-in: b790c91b user: stephan tags: trunk)
19:09
Implemented Stmt.get() and friends for WASM OO #1 wrapper. Added basic tests for prepare/step/get. Restructured module init output to introduce only 1 global-scope symbol instead of 2. (check-in: 601dc3fa user: stephan tags: trunk)
16:25
WASM: added bindings for sqlite3_compileoption_get/used(), moved OO #1 into sqlite3-api.js since it can only be used from the same thread as that API and separating them complicates client-side use. Started adding test utilities and tests for the OO1 API. (check-in: f3bc0328 user: stephan tags: trunk)
14:07
WASM OO wrapper #1: prepare() and bind() APIs are in place but are untested, pending fetch/get APIs. (check-in: 84c8f63a user: stephan tags: trunk)
00:27
Build refactoring for the fiddle/wasm bits. Set up wasm binding of a chunk of the core C API and added some infastructure for creating test pages for it. (check-in: dea098b6 user: stephan tags: trunk)

Defer materializing a view or subquery until the materialization is actually needed, so that if it is not needed, not useless work is performed. (Closed-Leaf check-in: 16bf3506 user: drh tags: deferred-materialize)
15:54
Fix a typo in a comment. (check-in: 34d7045b user: drh tags: deferred-materialize)
15:12
Use the newer OP_BeginSubrtn opcode instead of OP_Integer to start the subroutine used to matrialize a view. This does not change execution but does make the byte code a little easier to read. (check-in: cebd4fd6 user: drh tags: deferred-materialize)
14:19
fiddle: refactor into main thread (UI) and worker thread (wasm module). Added bits needed to support triggering sqlite3_interrupt() but do not yet have a second SharedWorker to test it with. (check-in: 5ff33268 user: stephan tags: trunk)
00:45
fiddle: add a selection list of example queries. (check-in: 74abf039 user: stephan tags: trunk)
00:01
In the shell WASM build, call open_db() early so that we can get access to the global db handle from certain experimentation-only function without having to first run some SQL code. (check-in: 31706ef8 user: stephan tags: trunk)
2022-05-20

Added a disclaimer about fiddle's experimental and subject-to-change/removal nature. (check-in: 75b4f574 user: stephan tags: trunk)
16:59
Merge the changes to support the "fiddle" extension. (check-in: 58585f01 user: drh tags: trunk)
16:49
When building fiddle from its own directory (e.g. from emacs instead of the normal build process), force -O0 the sake of compilation speed. The top-level build now defaults to -Oz, which is more appropriate for that case. (Closed-Leaf check-in: 56b82ae8 user: stephan tags: fiddle)
16:42
Tweaks to the fiddle make target so that it builds with all of the same extensions as the standard CLI. (check-in: d46a6cb9 user: drh tags: fiddle)
16:30
Added a toggle to swap input/output field positions and simplified setup of checkboxes which toggle a CSS class on a given element. (check-in: eae3ab10 user: stephan tags: fiddle)
16:11
Default to top/bottom layout with input on the bottom. Offer a toggle to swap input/output positions. (check-in: 362d236a user: stephan tags: fiddle)
15:58
Numerous layout tweaks, the most significant being that the layout now adapts to the window size. Swapped positions of the input/output areas. This version supports, by uncommenting a few bits, a jquery.terminal-based view but alternatives to that 300kb dependency are still under investigation. (check-in: 1aad3642 user: stephan tags: fiddle)
10:58
fiddle make target now accepts fiddle_cflags=... from the CLI to overrid -Ox and such for one-off builds. (check-in: 4609a4f8 user: stephan tags: fiddle)
10:38
Ensure that the output area is cleared of any init-time messages which the emscripten bootstrapping process emits when downloading of the wasm module is slow. (check-in: 1d8d0593 user: stephan tags: fiddle)
10:24
#if'd out the '.log' command in WASM builds. Cleaned up the user-visible parts of the WASM module initialization. (check-in: b5fa12f8 user: stephan tags: fiddle)
09:55
Split the fiddle JS code into separate pre-/post-init files to simplify editing. emcc will combine these into the final fiddle.js, so the number of output deliverables does not change. (check-in: d3d8ea01 user: stephan tags: fiddle)
09:22
Added an option to auto-clear the output area before submitting the input. Experimentally inverted the colors in the input/output areas. (check-in: 1a1e4e7f user: stephan tags: fiddle)
01:12
Replaced the toggle for the notes/caveats section of the fiddle UI with a button to remove that section. (check-in: 6661d605 user: stephan tags: fiddle)

#if out the '.load' command in WASM builds. Several UI layout tweaks. (check-in: 67d98297 user: stephan tags: fiddle)
22:58
In wasm builds, ifdef out shell commands which require file I/O, pipes, or which trigger an exit() (.quit and .exit). Documented some of the quirks and limitations of the C/WASM crossover. Keep the JS code from calling into the C code after an exit() has been triggered. (check-in: bee436e6 user: stephan tags: fiddle)
21:18
Improved handling/reporting of conditions which trigger an exit() from native code, e.g. calling the '.read' command. Added a Help button which simply submits the '.help' command. Added commented-out variants of various -Ox flags to simplify experimenting with them. (check-in: bf06ddf4 user: stephan tags: fiddle)

Transitive equality constriants do not work on a RIGHT JOIN, since the right-hand side might be a non-matched row. (check-in: 0f96810b user: drh tags: trunk)
19:50
Walk back the optimization from check-in [cc458317bd77046c] that tries to reuse the same ephemeral cursor of a list subquery when that subquery is reused, as it does not work in cases where the list subquery is used both for lookups and for scans. (check-in: 12ee29d6 user: drh tags: trunk)
17:45
Defer generating WHERE clause constraints for a RIGHT JOIN until after the ON-clause processing for the RIGHT JOIN has done its own row elimination. This fixes and incorrect output from some RIGHT JOINs that was identified by forum post 41cc3851d864c5e6. (check-in: 238d9c24 user: drh tags: trunk)
16:38

Preliminary code to support RIGHT JOIN. Everything seems to work, except that the code to compute the unmatched rows for the RIGHT JOIN has not yet been added, so the result of a RIGHT JOIN is currently the same as an INNER JOIN. (check-in: 415abd67 user: drh tags: right-join)
17:01
Enhance the sqlite_dbpage fix at check-in 642a0b4752743 from about a month ago such that it still takes a transaction on all attached databases, but it only starts a read transaction for read-only operations, rather than starting a write transaction for everything.

The ".testctrl optimizations 0x400000" command disables the generation of OP_ReleaseReg opcodes. OP_ReleaseReg opcodes are usually only generated for SQLITE_DEBUG builds and are used to verify that registers are descoped propertly.

In setResultStrOrError(), if the input string pointer is NULL and hence the value gets set to an SQL NULL, then the Mem.enc field is uninitialized. So do not read it. This is a harmless OSSFuzz/ASAN found problem. (check-in: 47d0b1c4 user: drh tags: trunk)

For TCL extension: Cleanup TCL library interaction and interpreter management. Group code into more purpose oriented functions. Add .unknown dot command, delegating to TCL commands with "dot" names. Drop planned .eval new dot command. For shell: Implement undocumented .unknown dot command, doing little. Make dispatcher call .unknown's implementation for unknown dot command. Fix a command lookup bug exposed by above change to unknown handling. Add .eval dot command. Add options to .x command aimed at control of errors in command sequences. (a WIP) Make dispatcher report ambiguous dot command lookups, even with no extension. (check-in: 7616a6f4 user: larrybr tags: cli_extension)

00:25
Fixes to the version of "varsep" group_concat so that (1) it builds under separate compilation and (2) omits tabs in source code and (3) runs faster than trunk. This variant of the group_concat_varsep branch might be preferred over the tip because it preserves (undocumented) legacy behavior about the position of separators relative to terms. (check-in: 04399cf9 user: drh tags: group_concat-fix-legacy)

2021-09-27
17:11
Have the dbstat virtual table take a copy of each page buffer that it traverses instead of just a reference to the page-cache object. This avoids problems if an error causes transaction rollback while a dbstat cursor is open. dbsqlfuzz crash-417224040fee04f0f0e62b70265c518893b08769. (check-in: 6ab25f8b user: dan tags: trunk)

Dbsqlfuzz (a097eaad43c3c845b236126df92fb49b25449b0c) found a way to reach the assert() that was added to sqlite3_declare_vtab() by [eb94f4a8174436b1]. This check-in fixes the problem. (check-in: 857d26a6 user: drh tags: trunk)

Ensure that sqlite_stat1 and sqlite_stat4 are ordinary tables (not views or virtual tables) before trying to load them (dbsqlfuzz bc02a0cde82dee801a8d6f653d2831680f87dca1). This prevents sqlite3_declare_vtab() from running with db->init.busy turned on. Even so, enhance sqlite3_declare_vtab() to be able to deal with db->init.busy being on, in case there are undiscovered paths to that state. Each of these two changes are independently sufficient to prevent the problem fixed by the previous check-in [c7560c1329965ab5] but there is no harm in keeping that third layer of protection in place.

For ALTER TABLE RENAME COLUMN, do not try to filter virtual tables out of calls to sqlite_rename_column(). Let the function filter them itself. The WHERE clause can mistakenly let virtual tables through if the sqlite_schema table is corrupt. The sqlite_rename_column() function must deal with them.

One of the optimizations of check-in [de9c86c9e4cdb34f] does not work for terms originating in the ON/USING clause, as demonstrated by forum post 6cf3bb457c3f4685. This check-in disables that optimization for ON/USING terms. Also improve the TreeView display for the resulting "true"/"false" nodes to show that they originate from the ON/USING clause. Add a testcase() to the other optimization to show that it can still be used for ON/USING terms. (check-in: 1f679604 user: drh tags: trunk)

This is another alternative fix to the covering index on WHERE_MULTI_OR in a LEFT JOIN problem that is fixed on trunk nearby. In this alternative, covering indexes are simply disabled for WHERE_MULTI_OR on a LEFT JOIN. This might have run-time impact on some obscure queries.

This is an alternative fix to the covering index on WHERE_MULTI_OR in a LEFT JOIN problem that is fixed nearby.

If a subquery is used to drive an index, this change avoids making an extra copy of the result of that subquery.

This avoids a dangling pointer in AggInfo if sqlite3ExprAnd() is invoked by the push-down optimization. The dangling pointer appears to be harmless in release builds, only showing up in debug builds. Problem found by dbsqlfuzz. (check-in: 77a30f3f user: drh tags: branch-3.35)

Performance improvement in the comparison opcodes by rewriting an array lookup using pointer arithmetic. This makes gcc 5.4.0 builds with -Os both faster and smaller. Though I suspect that in newer compilers with better optimizers in will probably make no difference at all in the generated machine code. Later: Even though the new code is perfectly valid, and generates correct machine code that is both smaller and faster, UBSAN complains about it in OSSFuzz. So we will take it out. So here was have an example of OSSFuzz coercing a widely used application to become bigger and slower. (Leaf check-in: 4a8805d9 user: drh tags: gcc-opt)

Change the RETURNING algorithm so that outputs accumulate in an ephemeral table until all modifications have been completed, and only then do results start being returned. This should help prevent problems with interleaved sqlite3_step() calls on two separate DML statements. It also seems to be closer to how PostgreSQL works, which might prevent compatibility problems.

Reduce the N in the logN term for the sorting cost associated with computing DISTINCT by B-Tree by half, under the assumption that the DISTINCT will eliminate about half the rows of output.

When doing an UPDATE or DELETE using a multi-column index where only a few of the earlier columns of the index are useful for the index lookup, postpone doing the main table seek until after all WHERE clause constraints have been evaluated, in case those constraints can be covered by unused later terms of the index, thus avoiding unnecessary main table seeks. (check-in: 0ecda433 user: dan tags: branch-3.28)

19:58
Omit the unnecessary not-NULL check on the upper bound of a forward index range scan. The subsequent OP_IdxGT will always catch the NULL. Similarly, omit the not-NULL check on the lower bound of a reverse index range scan, as the SeekLE opcode will disallow the NULL. (check-in: e51ecadc user: drh tags: trunk)

When doing an UPDATE or DELETE using a multi-column index where only a few of the earlier columns of the index are useful for the index lookup, postpone doing the main table seek until after all WHERE clause constraints have been evaluated, in case those constraints can be covered by unused later terms of the index, thus avoiding unnecessary main table seeks.

Optimizations to the logic that converts main table accesses into equivalent index accesses. Code is now slightly smaller and faster than trunk. (Closed-Leaf check-in: 611b6404 user: drh tags: delete-bytecode-optimization)
20:04
For UPDATE and DELETE, use OP_DeferredSeek always. If the seek must later be resolved, add the OP_FinishSeek opcode after all WHERE clause terms have been processed. This obviates the need for the WHERE_SEEK_TABLE and WHERE_SEEK_UNIQ_TABLE flags to sqlite3WhereBegin() and the ensuing complication, and it allows the covering index optimization to be used further into WHERE clause processing. (check-in: a495f60d user: drh tags: delete-bytecode-optimization)
17:39
Experimental change to try to get some DELETE operations to access values using the index rather than the main table, so as to avoid unnecessary main table seeks. (check-in: 2f7cb6ab user: drh tags: delete-bytecode-optimization)

16:13
Change the sqlite3.pDfltColl (the default collating sequence for the database connection) so that it is the collating sequence appropriate for the database encoding, not the UTF8 collating sequence. This helps to ensure that the database encoding collation is always used, even for expressions that do not have an defined collating sequence. Ticket [1b8d7264567eb6fc].

If STAT4 determines that a WHERE clause term that is not used by an index has very high probability of being true, then do not use that term to reduce the estimated output row count. (check-in: 40739c79 user: drh tags: trunk)
16:46
Rework this changes so that instead of setting the WhereTerm.truthProb when a term is seen to be of low selectivity, it merely sets a new flag (the TERM_HIGHTRUTH flag) which causes whereLoopOutputAdjust() to ignore that term. (Closed-Leaf check-in: 4558163b user: drh tags: stat4-truthprob)

2020-01-06
20:48
In the typeof() optimization in OP_Column, expand the size of the bogus buffer provided for data so that it is big enough to cover the increased number of bytes displayed during register tracing from check-in [54553bf16fabd72d]. This is the correct fix for ticket [bbd55a97e66ff50d], though the earlier one does not hurt and is useful to retain. (check-in: e1154c39 user: drh tags: trunk)
19:30
Merge enhancements from trunk. (check-in: 9c50f6c2 user: drh tags: new-security-options)
19:23
Rewrite the (debugging use only) sqlite3VdbeMemPrettyPrint() function to use the safer StrAccum interface rather than writing directly into a static string buffer. Perhaps this will address ticket [bbd55a97e66ff50d], which we are unable to reproduce. (check-in: 69f6a7e4 user: drh tags: trunk)
18:59
Backout change [4d0b9109f7a5312d4e1] because the conditional it added is no longer reachable due to check-in [1409758f72c0206c]. (check-in: b3f26967 user: drh tags: trunk)

14:57
Improve a testcase in test/fuzzdata8.db to make it more resilient. (check-in: 139aefe6 user: drh tags: trunk)
14:50
Back out another NEVER added by check-in [7b62555e285f32d3] - the test case was already in test/fuzzdata3.db, but it only occurs if compiled without SQLITE_ENABLE_PREUPDATE_HOOK. (check-in: 61f873b1 user: drh tags: trunk)
14:00
Omit the omit flag from eq constraints on column "aggregate" of dbstat virtual tables. Fix for [727074e2]. (check-in: 74ef6f2b user: dan tags: trunk)
12:34
Restore a NEVER and an assert in btree that was removed by check-in [7b62555e285f32d3]. Dbsqlfuzz found test cases. (check-in: 04a05c83 user: drh tags: trunk)
01:43
Enhance PRAGMA function_list so that it shows all instances of each FuncDef, the number of arguments, the encoding, the type, and the flags. Use this capability to locate and fix incorrect function flags in the standard build. (check-in: 9ca906d2 user: drh tags: new-security-options)
2020-01-03
21:57
Invert the SQLITE_FUNC_SAFE bit to be SQLITE_FUNC_UNSAFE. The external bit is still SQLITE_INNOCUOUS. It gets inverted as the appdef function is registered. (check-in: 1c266cb3 user: drh tags: new-security-options)
20:57
When UNSAFE_IN_VIEW is disabled, only allow functions in views that are tagged with SQLITE_INNOCUOUS. (check-in: 9ee79b25 user: drh tags: new-security-options)

16:38
Improvement to check-in [7405e98225761180] so that missing or null filenames given to the zipfile extension throw an immediate error. (check-in: 523e09bd user: drh tags: trunk)
15:51
Improve a specific case of early database corruption dectecion in the b-tree layer. (check-in: ceacc28b user: dan tags: trunk)
15:22
Merge fixes from trunk. (check-in: 002406df user: drh tags: new-security-options)
14:34
Remove an over-zealous ALWAYS() macro and add a test case that shows that the conditional can sometimes be false. (check-in: 536e9a9d user: drh tags: trunk)
14:27
Fix a possible NULL pointer dereference caused by using a "VALUES(...)" as a component of a compound SELECT with non-integer ORDER BY clause terms. (check-in: 9d791116 user: dan tags: trunk)
14:16
Fix the OP_Copy-coalesce optimization so that if the previous row happens to end with OP_Copy but is not a candidate for the optimization due to jumps, then the optimization is correctly bypassed. (check-in: b36126c1 user: drh tags: trunk)
13:55
Ensure that when a Select object is reset a new, empty, SrcList is allocated. (check-in: 4889cbf8 user: dan tags: trunk)
02:20
When generating the name of a view (or common table expression) because the SQL does not specify a name, avoid the names "true" and "false" which might be confused for the boolean literals of the same name, leading to an inconsistent abstract syntax tree. (check-in: ff9492d3 user: drh tags: trunk)
00:28
Fix a problem in sqlite3TreeViewBareExprList() in which the routine was not interpreting the new ExprList format correctly. (check-in: cd56872a user: drh tags: trunk)

23:50
Merge enhancements from trunk. (check-in: 091403a6 user: drh tags: new-security-options)

Do not allow the zipfile virtual table to start a transaction if no filename has been specified. (check-in: 7405e982 user: drh tags: trunk)
19:50
Fix some test logic in the OP_Delete opcode so that it works after a cursor-trip. (check-in: 28900e5c user: drh tags: trunk)
18:37
Ifdef-out code that is only possible with the sessions extension. (check-in: 4fcf07f7 user: drh tags: trunk)
17:46
Have the OP_ReleaseReg opcode also invalidate the registers if P5 is non-zero. (check-in: 937be221 user: drh tags: trunk)
16:24
Handle blobs that are the return values of functions being cast to text in utf16 databases in the same way as blobs read directly from the database. Fix for [771fe617]. (check-in: e782096a user: dan tags: trunk)
15:02
Fix the OP_Move opcode so that it correctly manages dependency tracking. This change impacts debugging builds only. (check-in: 5377add4 user: drh tags: trunk)
14:42
Enhancements to aid testing and debugging: In PRAGMA vdbe_trace=on output, show pScopyFrom dependencies on register values. Add the sqlite3VdbeRegisterDump() procedure, callable from a debugger, that shows the values of all registers. Pass the VDBE pointer into test_trace_breakpoint() so that sqlite3VdbeRegisterDump() is callable from the breakpoint. (check-in: 9886cb4b user: drh tags: trunk)
13:26
Add the test_trace_breakpoint() subroutine that is invoked after each instruction is printed while running PRAGMA vdbe_trace=on. Only works for SQLITE_DEBUG builds. Also add parameters "pc" and "pOp" to test_addop_breakpoint() to make it easier to set conditionals. (check-in: 49a6368c user: drh tags: trunk)
02:50
Use OP_Copy instead of OP_SCopy to move the results of a scalar subquery. (check-in: 435c272d user: drh tags: trunk)
00:45
The sqlite3WhereEnd() call now unwinds all Expr modifications made by the sqlite3WhereBegin(). (check-in: 7bfd42f1 user: drh tags: trunk)
2020-01-01
23:02
Provide the -DSQLITE_ENABLE_INTERNAL_FUNCTIONS=1 compile-time option. Fix the ".testctrl internal_function" command in the CLI so that it does not signal an error on a valid input. (check-in: 8ee2ce92 user: drh tags: trunk)
21:14
When generating code for a subquery, make a copy of the Select object and generate the code out of the copy, in case the code generator makes modifications to expression and the Select object needs to be reused. (check-in: 4edddcc0 user: drh tags: trunk)
20:17
Ensure that when code for a scalar SELECT featuring window functions is generated more than once by the planner, separate ephemeral tables are opened for each instance. (check-in: ce141732 user: dan tags: trunk)
16:43
Fix the sqlite3ExprImpliesNonNullRow() routine so that it correctly handles a numeric comparison of two AND subexpressions. (check-in: 07e504d5 user: drh tags: trunk)
15:43
New test-only SQL functions: implies_nonnull_row(), expr_compare(), and expr_implies_expr(). The SQLITE_TESTCTRL_INTERNAL_FUNCTIONS test-control is modified to toggle internal function access on and off for a single database connection. (check-in: 473892a8 user: drh tags: trunk)
13:55
Factor out code generation for in-line SQL functions into a separate routine inside of expr.c. (check-in: 586a65a2 user: drh tags: trunk)

2019-12-31
23:17
Remove an incorrect assert() statement. Ticket [46fcd700b855e6d1] (check-in: eca7ec9c user: drh tags: trunk)
22:52
Experimental branch with new sqlite3_db_config() options that could possible enhance security for applications reading potentially compromised database files. (check-in: 96a2db26 user: drh tags: new-security-options)
18:39
Also set the SQLITE_DIRECTONLY flag on the load_extension() function. (check-in: 3bd095a5 user: drh tags: trunk)
18:12
Set the SQLITE_DIRECTONLY flag on the fts3_tokenizer() function of FTS3, thus preventing that function from being called from within a trigger or view. (check-in: f3171dc2 user: drh tags: trunk)
15:12
Refactor names. Use "small" instead of "mini" to describe the smaller of the two lookaside memory allocation sizes. (check-in: 88d24498 user: drh tags: two-size-lookaside)
14:49
Merge recent enhancements from trunk. (check-in: 39d55579 user: drh tags: two-size-lookaside)
12:18
The OP_ResultRow opcode releases the SCopy dependences on all its registers, as the values in those registers will not be reused. (check-in: 1dc83c5d user: drh tags: trunk)
2019-12-30
23:50
Back out the NEVER() from check-in [40d10e7aad5b8992] because it is reachable after all. Ticket [892575cdba4e1e36] (check-in: f481636f user: drh tags: trunk)
23:41
Add an ALWAYS() to a conditional which is apparently always true. (check-in: ea44c607 user: drh tags: trunk)
20:42
Put a NEVER() on a defensive branch. (check-in: 40d10e7a user: drh tags: trunk)
20:42
Fix a typo in a comment. No changes to code. (check-in: d4813a8d user: drh tags: trunk)
14:32
Do not use HIDDEN columns for NATURAL joins. Fix for [7c0e06b16]. (check-in: ab09ef42 user: dan tags: trunk)
06:55
In ALTER TABLE, rename columns and tables in expressions that are optimized out by the "AND 0" optimization. Doing this also fixes an otherwise harmless assert() failure. (check-in: a9e0354c user: dan tags: trunk)
2019-12-29
22:08
Do not allow triggers that run as part of REPLACE conflict resolution during an UPDATE to modify the the table being updated. Otherwise, those triggers might delete content out from under the update operation, leading to all kinds of problems. Ticket [314cc133e5ada126] (check-in: db4b7e1d user: drh tags: trunk)
00:52
Add the OP_FinishSeek opcode which completes an OP_DeferredSeek if the seek has not already completed. Also add the sqlite3WhereUsesDeferredSeek() interface to the query planner. The UPDATE implementation adds an OP_FinishSeek before running the final OP_Insert if one is needed. Ticket [ec8abb025e78f40c] and also an assertion fault reported by Yongheng. (check-in: 21ef6e99 user: drh tags: trunk)
2019-12-28
18:25
Do not attempt to flatten compound sub-queries in a FROM clause into the parent if any component of the sub-query uses a window function. (check-in: eeb76f62 user: dan tags: trunk)
18:08
Change an assert() in where.c to a testcase() macro, since the condition may be false. This was a problem with the assert() only, there is no bug in release builds that omit assert(). (check-in: 82be135d user: dan tags: trunk)
16:20
Disable early coding of transitive constraints at the end of each loop in the WHERE clause processing if the loop being coded is for a LEFT JOIN, even if the loop is part of an OR-clause optimization for virtual tables. Test cases in TH3. (check-in: 9421b442 user: drh tags: trunk)
15:24
Fix an instance where the planner might choose to use the OR-optimization when it adds no benefit. The same quirk causes an assert() to fail. This is not a bug in released versions - without the assert() the library still gets the right answer, it just does so less efficiently than it should. (check-in: f4bed1d7 user: dan tags: trunk)
14:33
Further improvements to .wheretrace during loop code generation. (check-in: c4d5b75c user: drh tags: trunk)
14:07
New enhancements to .wheretrace. The 0x20000 flag shows the WHERE clause before and after coding each loop. The 0x800 flag shows status at the start and at the end of each loop. An extra "C" tag is shown on coded terms. (check-in: 59cc46e5 user: drh tags: trunk)
13:39
Expose some of the Where data structure debug printing routines to the entire WHERE-clause processing module. (check-in: 85e76887 user: drh tags: trunk)
13:17
Add the --enable-all option to the main configure script as a short-hand to enable FTS4, FTS5, Geopoly/Rtree, JSON, and Sessions. In the amalgamation-autoconf, the --enable-rtree option (which is enabled by default) also now activates Geopoly. (check-in: 52ea0672 user: drh tags: trunk)
13:01
Simplifications to the initialization of the sqlite3_index_info structure that is used to communicate with virtual table modules. Avoid adding unused constraints to the sqlite3_index_info structure. Extra constraints are harmless, but might be confusing to people trying to understand the code. (check-in: 5e6357fc user: drh tags: trunk)
12:33
If the ".wheretrace 0x10000" bit is set, print WhereTerm.prereqAll and .prereqRight fields in the WhereTerm trace output. (check-in: a4f330b1 user: drh tags: trunk)
11:55
Two new test cases added to test/fuzzdata8.db. (check-in: 1be2c18f user: drh tags: trunk)
09:08
Second attempt to fix a problem with unwinding the WITH stack of the Parse object following an error. (check-in: 315d1f1a user: dan tags: trunk)
08:33
Merge latest trunk changes with this branch. (Closed-Leaf check-in: d693be37 user: dan tags: better-error-handling-1)

Fix an assert() failure in altertable3-22.4. (check-in: c566a91d user: dan tags: better-error-handling-1)
03:55
Fix a faulty assert() associated with query search limiting query plans. (check-in: 0d743585 user: drh tags: trunk)
02:40
Convert an assert() back into a conditional. The conditional was converted into an assert() by check-in [6ae4ad6ebee4db88] (2009-05-28) because we were unable to find a test case for it. Yongheng's fuzzer just now found that test case. (check-in: 4d0b9109 user: drh tags: trunk)
01:52
When an INSERT is receiving content from a SELECT, run an OP_ReleaseReg opcode at the top of each iteration of the loop in order to prevent spurious OP_SCopy misuse complaints. Ticket [de4b04149b9fdeae] (check-in: 6afadd3b user: drh tags: trunk)
00:36
Recompute the values for all generated columns after NOT NULL ON CONFLICT REPLACE constraints fire. Tickets [37823501c68a09f9] and [5fbc159eeb092130]. (check-in: 4cc12c18 user: drh tags: trunk)
2019-12-27
20:54
Do not attempt to unwind the WITH stack in the Parse object following an error. This fixes a separate case to [de6e6d68], but also causes an assertion fault at select.c:4666 for test case altertab3-22.4. (check-in: d29edef9 user: dan tags: better-error-handling-1)
20:06
Remove a NEVER() that is no longer true. Fix for [36ffedcb9]. (check-in: 597896ed user: dan tags: trunk)
19:46
Fix a problem involving window function aliases being referenced from sub-selects. (check-in: e3b5fc05 user: dan tags: trunk)
18:15
Add a missing "ifcapable rtree {...}" line to the window1.test test module. (check-in: 4e6fbb1a user: drh tags: trunk)
16:25
Fix a problem with window functions in aggregate queries that do not have GROUP BY clauses. (check-in: 99609786 user: dan tags: trunk)
15:31
Do not mistake constant integers in a PARTITION BY expression for references to ORDER BY style references to values returned by the SELECT statement. (check-in: 45c64d39 user: dan tags: trunk)
13:30
Follow-up to check-in [c8c6dd0e6582ec91] - change the xAccess() method to return true if the file exists and it is anything other than a regular file, or if it is a regular file with a non-zero file size. (check-in: 8a39803e user: drh tags: trunk)
08:57
When determining if an aggregate within a sub-query should be processed as part of the sub-query or an outer query, consider any FILTER clause in the same way as the arguments to the aggregate. (check-in: 1ffc045d user: dan tags: trunk)
01:50
Ensure that the Pager.changeCountDone flag is cleared whenever dropping the write lock, even when transitioning from EXCLUSIVE locking mode into NORMAL locking mode while in WAL mode. Ticket [fb3b3024ea238d5c]. (check-in: 846b1de6 user: drh tags: trunk)
00:19
Fix buffer underflows in the zipfile extension associated with zero-length or NULL filename in the ZIP archive. But report on the mailing list by Yongheng and Rui. (check-in: 465a15c5 user: drh tags: trunk)
2019-12-26
23:40
If an UPSERT can cause an Abort due to a constraint failure, make sure the query planner knows this. Ticket [7c13db5c3bf74001]. (check-in: f14ce948 user: drh tags: trunk)
23:16
An UPDATE of a table that is indexed by a constant virtual column that uses the one-pass optimization might cause the table seek to be omitted before reaching row DELETE/INSERT.

In the xAccess() method of the unix VFS, return true if the named object is a directory, regardless of what stat() reports as the st_size for the object. Different filesystems report st_size differently for directories. Problem reported on the mailing list by Stefan Brüns. (check-in: c8c6dd0e user: drh tags: trunk)

When the sqlite3WindowRewrite() routine detects and error, have it convert the SELECT statement into just "SELECT null" so that it does not leave the parse tree in a goofy state that can cause problems with subsequent code before the stack has a chance to unwind and report the error. Ticket [d87336c81c7d0873] (check-in: fa58aad4 user: drh tags: trunk)

Backout the early VTable cursor close change from yesterday, as Yongheng and Rui have found a test case for which it fails. The new test case is added to fuzzcheck. (check-in: ddb10f03 user: drh tags: trunk)
20:51
Fix a problem causing fts5 integrity-check failures if numeric values are inserted into a table within a utf-16 database. Fix for [752fdbf6]. (check-in: bae060f3 user: dan tags: trunk)

20:41
Thoroughly reset the rtree cursor at the start of each VFilter operation, including clearing its cache. This prevents left over pages in the cache which can cause problems on shutdown after a LEFT JOIN. Ticket [5eadca17c4dde90c] (check-in: 4c50afaf user: drh tags: trunk)

14:20
For expressions like (x, y) IN (SELECT ...) where the SELECT uses window-functions, require that all columns on the LHS be indexed before an index can be used. Fix for [d9ed4ebe]. (check-in: 0b1dbd60 user: dan tags: trunk)
13:24
Fix a shift-overflow problem in yesterday's check-in [36fdeb4f0a66970a] that OSSFuzz helpfully discovered overnight. Thanks Google. (check-in: bff38e2b user: drh tags: trunk)
03:37
Fix the OP_Cast operator so that when casting to TEXT, it always leaves the result in the encoding of the database. Ticket [0911b5d161b039c6]. Test cases in TH3. (check-in: f347744e user: drh tags: trunk)
02:43
Change the assert() back into a testcase(). See also check-ins [9ab985a9c8160b90] and [ddb17d92df194337] and other check-ins that those reference. Fix for ticket [9d708e474201c001] (check-in: 2c44c734 user: drh tags: trunk)
02:18
Enhance the sqlite3VdbeMemAboutToChange() shallow-copy validation mechanism by adding the new OP_ReleaseReg opcode to tell MemAboutToChange() that a range of registers is no longer needed so that the source register can be freely changed. This is a change to debugging and test builds only and does not impact release builds. Fix for ticket [c62c5e58524b204d] and [5ad2aa6921faa1ee]. The previous fix to ticket [5ad2aa6921faa1ee] is backed out by this change since this change is a better fix. (check-in: 36fdeb4f user: drh tags: trunk)
2019-12-22
23:48
Change the code generator for the IN operator so that it avoids creating OP_Eq and OP_Ne opcode with the same P1 and P3 arguments. This enables us to back out check-in [ddb17d92df194337] and also fix ticket [188f912b51cd802]. (check-in: 9ab985a9 user: drh tags: trunk)
20:29
Make a hard copy of strings in constraint checks prior to applying OP_RealAffinity, to avoid problems with a pointer accounting assert. This change is not strictly necessary - the correct answer is obtained without it and no UB occurs - however the pointer accounting asserts are useful to prevent other problems so it is a simple matter to bring this piece into compliance. Ticket [5ad2aa6921faa1ee] (check-in: 89a9dad6 user: drh tags: trunk)
20:03
When constructing the virtual MATCH term of the WHERE clause for a virtual table that is in a LEFT JOIN, be sure to set the correct Expr.iRightJoinTable value. This value does not appear to ever be used, except inside of a single assert(). But it is good to set it correctly, nevertheless. This fixes ticket [7929c1efb2d67e98], which as far as I can tell is completely harmless. (check-in: ef604882 user: drh tags: trunk)
19:41
In the WHERE clause debugging output (the .wheretrace output) show the parent index of any WhereTerm that is a child. (check-in: 7fc73332 user: drh tags: trunk)
18:55
Fix to the optimization of check-in [a47efb7c8520a011] that reads the values of expressions used in an index-on-expression directly from the index rather than recomputing the value. If the expression has a top-level COLLATE or unlikely() operator, be sure to clear the corresponding flags prior to converting it into a TK_COLUMN expression. Failure to do this is most likely harmless in production, but might cause an assertion fault in debugging builds. Ticket [b0cb8aff561a6dcd]. Test cases in TH3. (check-in: 56539e1c user: drh tags: trunk)
18:23
Back out the asserts of check-ins [a500893b6f64aced] and [d9c9fe9f5ad3fc91] as ticket [1b06916e01c82b66] demonstrates a case that refutes them. (check-in: ddb17d92 user: drh tags: trunk)
18:06
When parsing a CREATE TABLE from the sqlite_master table, delete the CHECK constraints if there are any errors, since there might otherwise be attempts to use those CHECK constraints if PRAGMA writable_schema=ON is set. This undoes the fix in check-in [ea721b34477ab8b4] for a more general solution. (check-in: a982e643 user: drh tags: trunk)
17:32
Ensure sqlite3WindowRewrite() is called on a SELECT statement before any terms aremoved from it as part of IN() clause processing. Fix for [f00d096ca]. (check-in: 8c856404 user: dan tags: trunk)
14:29
Fix "PRAGMA data_version" so that it works the same way with locking_mode=PERSIST and journal_mode=PERSIST configured. Fix for 7a458c2a5f. (check-in: 45748e2d user: dan tags: trunk)

Fix a spurious report of corruption from the fts3/4 integrity-check triggered by using the languageid option. (check-in: 70815e27 user: dan tags: trunk)
19:37
When creating a new virtual table, ensure that the OP_ParseSchema opcode processes the correct entry in the sqlite_master table even if there is a second entry with the same name and table values due to database corruption and the use of writable_schema=ON. Dbsqlfuzz find. (check-in: 4dbb6e1c user: drh tags: trunk)
14:09
When a corrupt schema is loaded using writable_schema=ON, the CHECK constraints (or other expressions in the table definition) might not be fully resolved.

Fix harmless compiler warnings. (check-in: 2bbd014c user: drh tags: trunk)
13:24
Ensure fts5 consistently calls sqlite3_value_text() before sqlite3_value_bytes(). This matters when storing blobs in fts5 tables within utf-16 databases. Fix for [cf36cb4e02]. (check-in: c16305eb user: dan tags: trunk)

Fix the regexp extension so that it correctly translates all over-length 3-byte UTF8 sequences into 0xfffd. (check-in: 3d4c0bf8 user: drh tags: trunk)
20:37
When an error occurs while rewriting the parser tree for window functions in the sqlite3WindowRewrite() routine, make sure that pParse->nErr is set, and make sure that this shuts down any subsequent code generation that might depend on the transformations that were implemented. This fixes a problem discovered by the Yongheng and Rui fuzzer. (check-in: e2bddcd4 user: drh tags: trunk)
17:42
Detect the invalid use of NULLS LAST on an INTEGER PRIMARY KEY definition of a WITHOUT ROWID table. (check-in: 4417c5bf user: drh tags: trunk)

21:22
Change an unreachable testcase() into an assert() (check-in: 062e00c4 user: drh tags: trunk)
20:51
Continue to back away from the LEFT JOIN optimization of check-in [41c27bc0ff1d3135] by disallowing query flattening if the outer query is DISTINCT. Without this fix, if an index scan is run on the table within the view on the right-hand side of the LEFT JOIN, stale result registers might be accessed yielding incorrect results, and/or an OP_IfNullRow opcode might be invoked on the un-opened table, resulting in a NULL-pointer dereference. This problem was found by the Yongheng and Rui fuzzer. (check-in: 86297431 user: drh tags: trunk)
13:42
Add the --vdbe-debug option to fuzzcheck. (check-in: 289158aa user: drh tags: trunk)

Correctly unwind the savepoint stack if the database goes read-only in the middle of a savepoint. (check-in: a96d02b4 user: drh tags: trunk)
01:31
Remove an assert() in the code generator that can fail due to an invalid INSERT statement. The same assert() appears again in the VDBE and will fire there if the problem persists in an SQL statement that does not contain errors. Gramfuzz find. (check-in: 9bdd57cb user: drh tags: trunk)
00:05
When processing constant integer values in ORDER BY clauses of window definitions (see check-in [7e4809eadfe99ebf]) be sure to fully disable the constant value to avoid an invalid pointer dereference if the expression is ever duplicated. This fixes a crash report from Yongheng and Rui. (check-in: 1ca0bd98 user: drh tags: trunk)
2019-12-17

Clean up the ExprList that holds the names of columns in a CTE before checking for unused references in the ALTER TABLE implementation. (check-in: 8223e79f user: drh tags: trunk)
2019-12-16
16:52
When a table is part of a LEFT JOIN and should be a completely NULL row due to the semantics of a LEFT JOIN, make sure any generated columns on that row evaluate to NULL. Ticket [3b84b42943644d6f] (check-in: 02714914 user: drh tags: trunk)
2019-12-15
02:49
Ensure that all ON CONFLICT REPLACE indexes are sorted to the end of the list of indexes for a table, even for weird cases where the same UNIQUE constraint occurs twice with the ON CONFLICT REPLACE clause only on the second one. This avoids an out-of-order contraint processing problem that can arise due to the optimization of check-in [469a62ca33081854]. (check-in: 1e3918ca user: drh tags: trunk)
00:36
Abort the OP_Savepoint opcode early if a virtual table xSync method fails, perhaps due to an interrupt. (check-in: 672e749a user: drh tags: trunk)
2019-12-14
19:55
When a generated column expression is initially parsed, if it contains errors convert the expression to a simple NULL. This prevents additional pieces of the expression tree that are allocated from lookaside from leaking into the schema, where lookaside allocations are not allowed. (check-in: a89b3860 user: drh tags: trunk)
18:08
Due to the previous change, the p5 parameter to OP_VColumn no longer ever contains extraneous bits, so change a testcase() into an assert() to show as much. (check-in: 5b4a88cd user: drh tags: trunk)
17:43
Do not set OP_Column flags on the instructions generated by sqlite3ExprCodeGetColumn() if the opcode generated is not really an OP_Column, which might happen if the column is virtual. Fix for ticket [b439bfcfb7deedc6] (check-in: 2401e047 user: drh tags: trunk)
15:01
Make the sqlite3ExprCodeTarget() expression code generator routine robust in the face of unknown opcodes - it simply generates a NULL value. (check-in: f8e876c8 user: drh tags: trunk)

Patch to the page cache to avoid harmless pointer arithmetic that due to bugs in the STD-C spec is technically UB. This is to fix a harmless UBSAN complaint that OSSFuzz is hitting. (check-in: c29fc212 user: drh tags: trunk)
16:04
Change the default lookaside configuration to 40 slots of 1200-bytes each. This actually works out to 30 big slots and 93 small slots using the mini-lookaside allocator. We get the same (or better) lookaside coverage but with 72KB less memory per connection. (check-in: 47b71a84 user: drh tags: two-size-lookaside)

Remove unused macros formerly used to define built-in aggregate functions. (check-in: 3ef0d44e user: drh tags: trunk)
01:12
Reduce the size of ExprList to 24-bytes per entry, down from 32-bytes per entry. This helps keep lookaside allocations in the mini-size. (check-in: bda92d92 user: drh tags: two-size-lookaside)

Tie up the loose ends in the ExprList size reduction. (Leaf check-in: 59d0f3af user: drh tags: two-size-lookaside, exprlist-size-reduction)
2019-12-12
22:11
Work toward reducing the incremental size of an ExprList object to 24-byte per entry, from 32-bytes (on a 64-bit machine). This helps the new mini-lookaside allocator to run better by avoiding excessive reallocs. The current change mostly works, but still has a few loose ends to tie up. This check-in is merely a snapshot to save my work. (check-in: fdda76cf user: drh tags: two-size-lookaside, exprlist-size-reduction)

Fix an issue where malloc could be used to fulfill a small allocation when a large lookaside slot could have beeen used instead. (check-in: 611020e3 user: numist tags: two-size-lookaside)
20:22
Change the name of the Expr.a.zName field to zEName, so that it has a name that is distinct from other fields and variables and is hence easier to grep for. (check-in: d3783357 user: drh tags: two-size-lookaside)
17:17
Change the size of a mini-lookaside allocation to a macro (MINI_SZ) rather than a magic number (128). (check-in: 5e1949bc user: drh tags: two-size-lookaside)
16:49
Merge enhancements from trunk. (check-in: 6cb053f9 user: drh tags: two-size-lookaside)
15:19
Factor out the conditional (which is only true for rare errors) from the notValid() function in resolve.c, for a performance improvement and size reduction. Also cause failures to set the Expr node to a NULL operator so that it does not cause problems later in case PRAGMA writable_schema=ON has been set. Test cases in TH3. (check-in: c6af9f65 user: drh tags: trunk)

16:22
Strengthen check-in [83da4d4104ee1870] by ignoring *all* WHERE-clause constraints for a virtual table that is the right table of a LEFT JOIN, as such constraints are never useful. This fixes an issue discovered by Manuel Rigger. (check-in: 840de36d user: drh tags: trunk)
15:07
When trying to drop a virtual table that has no xDestroy method, invoke the xDisconnect method rather than doing nothing, to avoid a memory leak. (check-in: 1fa29a5f user: drh tags: trunk)

Fix a gramfuzz find. If a partial index that does not reference any column of its table is used by an UPDATE statement in one-pass mode, then avoid the use of OP_DeferredSeek since the seek might not be resolved prior to the OP_Delete and OP_Insert that implement the UPDATE.

Fix to the rowvalue logic that avoids disabling rowvalue inequality contraints on a virtual table when the virtual table sets the omit flag. The logic has been incorrect since row-values were added. However, this does not come up often as very few virtual tables implement inequality constraints using the omit flag. Ticket [f096d191b6641daa] (check-in: b7810062 user: drh tags: trunk)

Revise the SQLITE_OPEN_NOFOLLOW so that it actually uses O_NOFOLLOW in the open() system call. This backs out the SQLITE_ACCESS_SYMLINK value but adds the new SQLITE_OK_SYMLINK return code from the xFullPathname method of sqlite3_vfs when that routine resolves symbolic links.

Avoid assuming that for "~ (? AND FALSE)" to be true, "?" must not be NULL, just as we do for "NOT (? AND FALSE)". Fix for ticket [c0390363]. (check-in: 84ae41fd user: dan tags: trunk)
14:25
Fix a potential buffer overrun in fts5 caused by corrupted database records. (check-in: c465d0eb user: dan tags: trunk)

Improve Lemon so that it enlarges some of its tables slightly in order to avoid having to index range checks on table lookups for a performance increase. (check-in: 4be6a23a user: drh tags: trunk)
2019-08-28
11:49
Fix an unreachable branch in sqlite3ParserFallback() (Closed-Leaf check-in: e059178b user: drh tags: lemon-optimization)
11:31
Further improvements to parser speed by enlarging lookup tables to eliminate the need to do range checking on the index prior to lookup. (check-in: 47d3e091 user: drh tags: lemon-optimization)
02:09
Increase the size of the yy_lookahead table so that it is never necessary to down bounds checking on the index. (check-in: bafd8723 user: drh tags: lemon-optimization)
2019-08-27
19:59
Add support for "ORDER BY ... NULLS FIRST" and "ORDER BY ... NULLS LAST". Use this to fix ticket [f8a7060e]. (check-in: 94085fb3 user: dan tags: trunk)
17:59
The ALWAYS() added by the previous check-in was incorrect. Take it back out. (check-in: 336235db user: drh tags: trunk)
17:28
Add ALWAYS() to an always true conditional that results from the previous check-in. Add a test case for ticket [dbaf8a6820be1ece] to supplement those already checked into TH3. (check-in: aff20980 user: drh tags: trunk)
17:01
Omit the "x IN (y)" to "x==y" optimization of check-in [e68b427afbc82e20] (and ticket [e39d032577df6942]) as it causes difficult affinity problems as demonstrated by ticket [dbaf8a6820be1ece] and the original assertion fault is no longer a factor due to countless other changes of the previous 5 years. (check-in: 7f5168a7 user: drh tags: trunk)
10:05
If a TEMP TRIGGER references an auxiliary schema, and that auxiliary schema is detached, move the trigger to reference the TEMP schema before completing the detach, so that the trigger does not hold a dangling schema pointer. Ticket [ac8dd4a32ba4322f] (check-in: 069c2f4c user: drh tags: trunk)

Improved detection of number of column mismatch for vector assignment in UPDATE statements. Ticket [78acc9d40f0786e8] (check-in: bd4bda73 user: drh tags: trunk)
13:45
Fix typo in a comment. No code changes. (check-in: d0cc06d8 user: drh tags: trunk)

Fix the built-in edit() SQL function in the CLI so that it works with zero-length blobs. (check-in: e3249012 user: drh tags: trunk)
21:11
Attempt to parse the NULLS LAST clause more efficiently. A few cycles were saved, but at the expense of more code. And there is a bug was introduced somewhere. Not worth continuing down this line. (Closed-Leaf check-in: 12d2cf88 user: drh tags: dead-end)
20:33
Move some things in parse.y so that TK_COLUMN and TK_AGG_COLUMN are assigned the same values as they are on trunk for a very small speedup. (check-in: d26fdfa3 user: dan tags: nulls-last)
17:09
Revise the VDBE comments for NULL-scan so that they also work make sense when reading a NULLS FIRST plan. (check-in: bfe79378 user: drh tags: nulls-last)
17:00
Additional simplifications of the WHERE loop code generator logic for NULLS LAST. (check-in: 1383680d user: drh tags: nulls-last)
16:12
Simplification of the WHERE loop code generator for NULLS LAST saves a few CPU cycles and about a hundred bytes of code space. (check-in: e3ed2f49 user: drh tags: nulls-last)
13:32
Invert the meaning of the regBignull flag so that it is 1 when doing the normal scan and 1 when scanning nulls. This enables the re-do jump at the bottom of the loop to be coded with a single OP_IfNotZero opcode, rather than a sequence of OP_If, OP_Integer, OP_Goto. (check-in: bf875e1a user: drh tags: nulls-last)
13:08
Extra VDBE comments in the NULLS LAST logic provide landmarks to help understand the EXPLAIN output. (check-in: 649b08ea user: drh tags: nulls-last)

16:38
Fix the likely(), unlikely(), and likelihood() functions so that they have no affinity, just like any other function. Ticket [7e07a3dbf5a8cd26] (check-in: 44578865 user: drh tags: trunk)
11:11
Fix a false-positive in sqlite3ExprNeedsNoAffinityChange(). Ticket [ac184eb571d5e6e0] (check-in: e62eddbb user: drh tags: trunk)
00:53
Fix the OP_SeekGE, OP_SeekGT, OP_SeekLE, and OP_SeekLT opcodes so that they preserve the datatype of the value in the register used as the key. Ticket [d9f584e936c7a8d0] (check-in: 81b9f0f5 user: drh tags: trunk)

Update this branch with latest trunk changes. (check-in: 6153bcf4 user: dan tags: nulls-last)
14:54
Avoid assuming that "column IS ?", where column is declared UNIQUE, matches only a single row (as "?" might be NULL). Fix for [b8689402]. (check-in: d02490a2 user: dan tags: trunk)
11:31
Fix a broken assert() in the fts3 snippet code that was failing for queries containging more than 64 phrases. (check-in: 4c01e017 user: dan tags: trunk)

When populating an ephemeral b-tree for the RHS of an IN(...) clause, avoid applying an affinity to a value that may be used later on for some other purpose. Fix for [c7a117190]. (check-in: 43e8b143 user: dan tags: trunk)
18:16
Add tests to ensure that this branch really does fix ticket [f8a7060ece]. (check-in: f8920664 user: dan tags: nulls-last)

Ensure the functions that appear to be constant are not factored out of expression that originate on the right-hand side of a LEFT JOIN. Ticket [6710d2f7a13a2997] (check-in: 500c9152 user: drh tags: trunk)
15:47
Merge trunk changes into this branch. (check-in: db1e6080 user: dan tags: nulls-last)

Activatate introspection pragmas by default. The new option SQLITE_OMIT_INTROSPECTION_PRAGMAS must be provided to keep them out. (check-in: 9c4bca64 user: drh tags: trunk)
00:53
The SQLITE_DIRECTONLY flag, when added to sqlite3_create_function() prevents the function from being used inside a trigger or view. (check-in: de767376 user: drh tags: trunk)
2019-08-16

23:11
Fix harmless compiler warnings in the TCL interface. (check-in: f17e7229 user: drh tags: trunk)
21:27
Add the SQLITE_DBCONFIG_ENABLE_VIEW option, together with a "db config" command in the TCL interface that can access that option as well as all the other sqlite3_db_config() boolean options. (check-in: 61b4bccd user: drh tags: trunk)
20:04
Provide the SQLITE_DIRECTONLY flag for app-defined functions that prohibits the use of those functions within triggers or views. (Closed-Leaf check-in: fc745845 user: drh tags: directonly)
14:35
Ensure that the optional "sz=N" parameter that can be manually added to the end of an sqlite_stat1 entry does not have an N value that is too small. Ticket [e4598ecbdd18bd82] (check-in: 98357d8c user: drh tags: trunk)
13:53
Ensure that SQLite does not attempt to process incompatible window functions in a single scan. Fix for [256741a1]. (check-in: 4f5b2d93 user: dan tags: trunk)
13:46
Avoid downgrading SQLITE_CORRUPT errors detected by the schema parser into SQLITE_NOMEM or SQLITE_ERROR errors. (check-in: b2e79f8f user: drh tags: trunk)
13:17
Ensure that the cell overwrite optimization does not overwrite the header of the b-tree page. (check-in: 4cc5694c user: drh tags: trunk)
00:04
Early detection out-of-bounds page numbers on the direct-overflow-read optimization gives consistent error messages regardless of whether or not the optimization is enabled. (check-in: b517a52f user: drh tags: trunk)
2019-08-14
15:17
Always check for reads past the end of the file on the in-memory journal driver. This used to be an assert(). (check-in: 4d41ca7d user: drh tags: trunk)
2019-08-13
20:34
Add some static to the 'regexp' extension. (check-in: a21d1dde user: mistachkin tags: trunk)
17:56
Update test cases so that they work with ICU enabled. (check-in: 408144a1 user: dan tags: trunk)

Make sure the btree cursor overflow cache is cleared when overwriting a cell in sqlite3BtreeInsert(). Ticket [3cf9bb227e9a5d32] (check-in: 7dae7b96 user: drh tags: trunk)
16:36
Experimental implementation of NULLS FIRST/LAST. This branch still has problems - the most significant of which is that ORDER BY clauses with a non-default NULLS FIRST/LAST qualifier can never use an index. (check-in: 07babb0f user: dan tags: nulls-last)
16:25
For the ".testctrl prng_seed" command in the CLI, if the argument is "random" then select a random integer seed and print the seed value on stdout. (check-in: 636ca447 user: drh tags: trunk)
15:37
Fix the build for compilation using separate files rather than the amalgamation. (Leaf check-in: 1e0f4869 user: drh tags: sha3)
15:19
Make the sha3 extension part of the amalgamation, enabled using SQLITE_ENABLE_SHA3. (check-in: a48a7b78 user: drh tags: sha3)
14:17
Add a TESTCTRL that disables the verification of type, name, and tbl_name in the sqlite_master table. (check-in: 48d9b48a user: drh tags: trunk)
00:08
Validate the type, name, and tbl_name fields of the sqlite_master table when loading the schema, unless writable_schema is engaged. (check-in: 724f4df9 user: drh tags: trunk)
2019-08-10
15:06
Fix the sqliteExprImpliesExpr() routine so that it recognizes that "(NULL IS FALSE) IS FALSE" doe not imply "NULL NOT NULL". Ticket [9080b6227fabb466] (check-in: da01ba4f user: drh tags: trunk)
14:35
Add extra test cases related to the previous commit. (check-in: 3c690b2b user: dan tags: trunk)

Remove two incorrect assert() statements from the logic used to derive column names and types from subqueries. (check-in: 712e4771 user: drh tags: trunk)
2019-08-09
20:26
Allow the RHS of a row-value IN operator to use a compound query with an ORDER BY clause. (check-in: eaf15d9b user: drh tags: trunk)
14:54
In shared-schema mode, handle the case where a connection has created a virtual-table object, but is later assigned a different shared-schema object for which the virtual-table schema has not yet been initialized. (check-in: e30c7414 user: dan tags: reuse-schema)
01:59
Modify signature of sqlite3VdbeChangeOpcode() to accept int instead of u32. (check-in: 68b7f2ac user: mistachkin tags: trunk)

19:40
Fix harmless compiler warnings. (check-in: 1eef4dde user: drh tags: trunk)
19:19
Remove support for SQLITE_ENABLE_STAT3. The sqlite_stat3 table is now ignored, if it exists. Run ANALYZE using STAT4 to get the equivalent functionality, which presumably everybody has been doing for a long time now. (check-in: f1cd234c user: drh tags: trunk)
18:49
Fix a case of the Expr.affinity to Expr.affExpr refactor that was missed in the [a29f2a7d07beff64] check-in. (check-in: 83450d10 user: drh tags: trunk)
16:23
More legacy STAT3 code removed. (Closed-Leaf check-in: 845d2f17 user: drh tags: omit-stat3)
15:47
Fix spurious "no such table: x1" errors in shared-schema mode that could occur when a query that is a join across two or more databases needs to call the xConnect() methods of a virtual table. (check-in: edf45cd7 user: dan tags: reuse-schema)
15:24
Remove support for STAT3. The sqlite_stat3 tables are ignored, if they exist. STAT4 continues to work as it always has, and as it is a superset of STAT3 is the recommended replacement. (check-in: 1e17ea2f user: drh tags: omit-stat3)
11:44
Fix a bug causing "no such table" and other similar sqlite3_prepare*() errors to return SQLITE_SCHEMA instead of SQLITE_ERROR in shared-schema mode when there is an attached database for which the schema has never been loaded. (check-in: 111e2c73 user: dan tags: reuse-schema)
01:39
Remove a NEVER() that is reachable from a corrupt database. (check-in: 30e6ee27 user: drh tags: trunk)
2019-08-07
19:57
Remove use of the affinity() function from view.test, as it is only available in SQLITE_DEBUG builds. (check-in: 7f2246a1 user: dan tags: trunk)
18:34
Add "set TMP=%CD%" to the start of each msvc script output by releasetest_data.tcl. Otherwise, since binaries compiled with SQLITE_TEST all choose the same sequence of pseudo-random numbers, collisions between temp file names cause errors when running multiple tests in parallel. (check-in: f5d0436d user: dan tags: trunk)
17:45
Eliminate some more cases of redundant sorting in window-function queries. (check-in: 8158d2ac user: dan tags: trunk)
13:25
Do not make SQLITE_READ authorizer calls for tables without names, as all such tables will be internal-use-only tables for subqueries and whatnot. (check-in: 193c87fc user: drh tags: trunk)
2019-08-06
21:16
Ensure that when the col in an operator like "val IN(col)" is a column of a view, its affinity is not used to coerce val. Fix for [0a5e2c1d]. (check-in: 17b3d221 user: dan tags: trunk)
20:55
Improved reuse of file descriptors for which close() is delayed to prevent clearing of posix advisory locks. (check-in: 509c1ba2 user: drh tags: trunk)
20:26
Enhance the ".recover" output in the shell to use double-quotes around table and column identifiers. (check-in: 846d2d2d user: drh tags: trunk)
18:40
Add "PRAGMA foreign_keys=OFF;" to the start of the script output by ".recover", just as is done for ".dump". (check-in: bfc29e62 user: dan tags: trunk)
15:32
Ensure that columns of views and sub-queries that are expressions with no affinity are comparied without any type conversions, as required in the documentation. Tickets [61c853857f40da49] and [d52a29a9e6bc55c5]. (check-in: 9c8c1092 user: drh tags: trunk)
15:18
Performance optimization to the new affinity handling logic. (Closed-Leaf check-in: c9724e76 user: drh tags: pending)
15:02
Add a multi-threaded test to threadtest3.c for the feature on this branch. (check-in: 62557fab user: dan tags: reuse-schema)
14:37
Use 0x40 (ASCII '@') instead of 0x00 to mean "no affinity" so that columns with no affinity can appear in a zero-terminated string. Use the new SQLITE_AFF_NONE macro for this new magic number. (check-in: e8234f69 user: drh tags: pending)
11:45
Add an assert() to the code on this branch. (check-in: fdd44bbb user: dan tags: reuse-schema)
2019-08-05
20:53
Ensure that columns of views and sub-queries that are expressions with no affinity are not assigned BLOB affinity. This matches the documentation. Fix for [61c853857f40da49]. (On a branch because there are still subtle issues.) (check-in: e15a0977 user: dan tags: pending)
20:45
Add test cases to this branch. (Closed-Leaf check-in: f37317d8 user: dan tags: tkt-61c853-A)
19:44
Fix the patch on this branch so that it works with sub-queries, as well as views. (check-in: 7480db30 user: dan tags: tkt-61c853-A)
19:34
The second option for [61c853857f40da49]: In this mode, columns of VIEWs and subqueries that are formed by expressions have affinity BLOB rather than affinity none, as has usually been the case for a while. But this mode fixes a couple of corner cases involving query flattening and the push-down optimization where that rule was violated. (Closed-Leaf check-in: 470ac8d5 user: drh tags: tkt-61c853-B)
19:32
One of two options on how to address ticket [61c853857f40da49]. In this mode, we back out the documentation change of [07b7749da88d54e5] and change the core to work as it has been documented to work since 2017, rather than how it has actually worked since 2009. (check-in: 09cd0c0c user: drh tags: tkt-61c853-A)
18:01
Refactor field Expr.affinity into Expr.affExpr to avoid confusion with other fields and variables named "affinity" and display affExpr it in sqlite3TreeViewExpr() output. (check-in: a29f2a7d user: drh tags: trunk)
16:22
Improved detection of corruption on the freeblock list of a btree page. (check-in: 4b00799b user: drh tags: trunk)
13:19
Fix a problem with renaming a table when a view or trigger within the schema uses a FILTER with an aggregate function that is not currently registered with the database. (check-in: 2ac0e42f user: dan tags: trunk)
12:55
Prevent an fts5 table from being its own content table, or part of a view that is the content table. (check-in: b6d52c93 user: dan tags: trunk)
2019-08-03
19:06
Strengthen an assert() in the WHERE clause code generator for the min/max optimization. (check-in: 1bd4b97d user: drh tags: trunk)
16:37
Fix a problem with queries of the form "SELECT min(<expr>) ... WHERE <expr>=?" where there is an index on <expr>. Fix for [71e183ca]. (check-in: d465c3ee user: dan tags: trunk)
16:17
In the ".wheretrace 0x100" debugging mode, show the structure of the main parameters to sqlite3WhereBegin() calls. (check-in: fd598e47 user: drh tags: trunk)
01:40
Add the SQLITE_TESTCTRL_PRNG_SEED which can control the PRNG seed either directly or through the schema cookie of a supplied database connection. (check-in: 2660e929 user: drh tags: trunk)
01:39
Give the SQLITE_TESTCTRL_PRNG_SEED two arguments. The second argument if not NULL is a pointer to a database connection which seeds the connection from its schema cookie. In this way, fuzzers can control the PRNG seed. (Closed-Leaf check-in: 49aa3448 user: drh tags: prng-seed-test-control)
2019-08-02
21:03

Improved fix for ticket [ced41c7c7d6b4d36] that keeps skip-scan enabled, but avoids identifying a skip-scan as order-distinct (because it is not) and thus forces a separate b-tree to implement the DISTINCT clause of a query.

18:35
A minor variation on check-in [1685610ef8e0dc] which (hopefully) makes the logic a little easier to follow. Also disallows the use of the double-quoted string hack in the query expression used for VACUUM INTO, which is not strictly required, but moves us toward the goal of disallowing the double-quoted string hack everywhere. (check-in: 3e1b55f3 user: drh tags: trunk)
17:14
Disallow string constants enclosed in double-quotes within new CREATE TABLE and CREATE INDEX statements.

(check-in: 1685610e user: dan tags: trunk)
10:36
Update the sqlite3ExprCompare() routine so that it does not think "? IS NOT TRUE" is the same as "? IS TRUE". Fix for [d3e7f2ba5b3]. (check-in: 99eba69b user: dan tags: trunk)
2019-05-18
21:22
Fix an assert() failure that could occur in a join query if the RHS of an IN() operator is a list containing correlated expressions. This problem was introduced by checkin [e130319317e7611938] which was part of the fix for ticket [787fa716be3a7f650c] - so this commit is part of that ticket's fix too.

01:22
Make sure the OP_Concat opcode always correctly zero-terminates a UTF16 string, even if the input strings are ill-formed. This is a followup to check-in [3a16ddf91f0c9c516a7] that fixes a case the previous check-in missed. Also add assert()s to prove correct zero termination. (check-in: d612fb78 user: drh tags: trunk)

17:10
Disable the optimization where a REAL value with no fractional part is stored as an INTEGER when the integer uses as much space as the real value it proposes to stand in for (8 bytes).

Remove some stale references to the addopcodes.tcl script from documentation. (check-in: c0381b0b user: drh tags: trunk)
20:56
Eliminate the tool/addopcodes.tcl script. The purpose of that script was to keep the number of parser codes below 256 in order to save parser table space. But we have long since blown through that ceiling so the addopcodes.tcl script was just needless complexity. There is no longer any reason to keep it around. (check-in: d2728192 user: drh tags: trunk)
20:47
Add further tests so that veryquick.test covers all vdbe branches. (check-in: cbc67de5 user: dan tags: trunk)

Add the ability to override the new corruption detection logic of the previous checkin, in order to exercise downstream corruption detection during testing. (check-in: e859d318 user: drh tags: trunk)
15:44
In the xfer-optimization, do early detection of when the source and destination index share the same btree, to avoid a long delay prior to reporting the database corruption. (check-in: af1e5873 user: drh tags: trunk)
2019-04-04

Correctly initialize the loadable extension thunk. (check-in: 4fca46de user: drh tags: trunk)
15:25
Simplification of the recent VACUUM changes that make the code more like what it was before the change. Also, make the VACUUM command a no-inline procedure to work around a performance regression. (check-in: 9cac5ac1 user: drh tags: trunk)
14:36
Fix an incorrect comment on a test case for rowid renumbering in VACUUM. (check-in: 0d293fb4 user: drh tags: trunk)
14:00
Only preserve rowid values for VACUUM INTO. Keep the legacy behavior of renumbering rowids for ordinary VACUUM. (check-in: 13a0ea64 user: drh tags: trunk)
2019-04-03
17:54
Add a defense-in-depth NEVER() test to the WAL cleanup code. (Leaf check-in: 1109942a user: drh tags: branch-3.27)

Small optimizations to the grammar for window functions save about 120 bytes of space in the parser tables. (check-in: bce01d95 user: drh tags: trunk)
17:45
Use a separate bit on db->dbOptFlags to disable the xInverse optimization on window functions, rather than reusing the query-flattener disable bit. (check-in: bc0fb1c3 user: drh tags: trunk)
17:45
Including the phrase EXCLUDE NO OTHERS in the frame-spec of a window function (which is the default setting for EXCLUDE) silently disables the xInverse optimization. This is a feature, but we will keep it undocumented for now in case we later decide it is a bad idea. (check-in: 10aedce3 user: drh tags: trunk)
13:10
Put the list of keywords in mkkeywordhash.c into alphabetical order. (check-in: ac98b23b user: drh tags: trunk)

Merge fixes from trunk. (check-in: 20372906 user: drh tags: apple-osx)
00:56
Make sure the MEM_FromBind bit inthe Mem.flags field is not included in the MEM_TypeMask. This critical changes was omitted from the previous two check-ins by mistake, and so those check-ins are not fully functional. (check-in: f7ba2daf user: drh tags: trunk)
00:48
Add new APIs to the extension loading mechanism. (check-in: 6f122faf user: drh tags: trunk)

16:23
Frame range comparisons can never be NULL because the values will have been checked for NULL prior to the test. (check-in: fa37cf9a user: drh tags: trunk)
15:55
Mark rowid-comparison opcodes as never-null for VDBE coverage tracking purposes. (check-in: a69bb4f2 user: drh tags: trunk)

Add a call to sqlite3FaultSim(410) inside of btreeRestoreCursorPosition() to simplify testing of error scenarios. (check-in: bb643bac user: drh tags: trunk)
18:39
The defragmentPage() routine detects corruption in the first-free-slot fields at offset 1 in the header and throws an error, rather than asserting. (check-in: fb125bd3 user: drh tags: trunk)
17:30
Add the blobio.c extension module implementing readblob() and writeblob(). Experimental. (check-in: e3fde56d user: drh tags: trunk)

Add an extra IO-error test to windowfault.test. (check-in: 5b8c44cd user: dan tags: trunk)
2019-03-29
17:26
Change the fts3_tokenizer() function to always return the pointer as a BLOB as long as the first argument is a bound parameter, regardless of the SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER setting. (check-in: 27160df7 user: drh tags: value_frombind)
15:21
Remove the unused P5 flag from the OP_Rewind opcode. (check-in: c2edbf3b user: drh tags: trunk)
13:17
Fix a fairly obscure problem causing the planner to sometimes choose sub-optimal plans for a query with a single virtual table in the FROM clause, and at least one IN(...) constraint in the WHERE clause. (check-in: f5752517 user: dan tags: trunk)
11:48
Fix typos in the comments of the sessions extension, one of which affects the generated documentation. No code changes. (check-in: 040d5d51 user: drh tags: trunk)
11:39
The two-argument version of fts3_tokenizer() works regardless of the value of SQLITE_DBCONFIG_ENABLE_FT3_TOKENIZER as long as the second argument is a bind parameter. (check-in: ab76e3a9 user: drh tags: value_frombind)

Initial implementation of the sqlite3_value_frombind() interface. (check-in: 98da62df user: drh tags: value_frombind)

13:35
More improvements to TreeView output for Window objects: (1) Show when the frame-spec is implied rather than explicit. (2) Move the FILTER clause out from within the OVER clause, making it a sibling of the OVER clause, to match syntax. (check-in: d6a07433 user: drh tags: trunk)
13:03
Improved TreeView display of Window objects. Change the Window.eType field to Window.eFrmType to avoid confusion with other "eType" values. (check-in: ec2f207d user: drh tags: trunk)

Fix an obsolete comment in the CLI. No code changes. (check-in: fade103c user: drh tags: trunk)
21:56
In the CLI, code the "sqlite_parameters" name directly rather than using a macro, for clarity of presentation for users who are reading the code for the purpose of seeing how the CLI implements parameter binding. (check-in: e775ef00 user: drh tags: trunk)
21:55
Remove a test from the index build logic which is no longer needed and is in fact unreachable. (check-in: 9b20ee10 user: drh tags: trunk)
21:35
Change the name of the parameter table in the CLI to "sqlite_parameters". Doing so involves adding SQLITE_DBCONFIG_WRITABLE_SCHEMA and allowing the creation of tables whose names begin with "sqlite_" and that are indexed while writable_schema is on. (check-in: 24ef3844 user: drh tags: trunk)
19:50
Earlier detection of corruption while added to the freelist. (check-in: 8c80b004 user: drh tags: trunk)
18:44
Fix a faulty assert() statement in balance_nonroot() - the assert() should use get2byteNotZero() instead of get2byte() for the corner case where the number cells is zero on a 65536-byte page. (check-in: bcbe7d96 user: drh tags: trunk)
15:09
Improvements to the help text in the CLI. (check-in: 919fec91 user: drh tags: trunk)
15:06
Fix the writefile() SQL function implemented by ext/misc/fileio.c such that any directories created have standard umask permissions, not permissions of the file that is to be written. (check-in: f11c8959 user: drh tags: trunk)
14:24
For the ".archive --update" command in the CLI, only update files if their mtime or mode has changed. To force an update, use the new --insert instead. (check-in: 191a023a user: drh tags: trunk)

13:53
We learn that readdir_r() is deprecated in favor of plain old readdir(), which is now suppose to be threadsafe using thread-local storage. So remove the use of readdir_r() from the test code. (SQLite itself never calls readdir() or readdir_r()). (check-in: 7a0a26ed user: drh tags: trunk)

2019-03-20
20:27
Experimental change to apply affinity before running CHECK constraints on an INSERT. Note that in the CHECK constraints, REAL affinity really is REAL affinity, and not numeric affinity. This causes failures in some tests that are assuming affinity is applied after CHECK constraints. (Leaf check-in: 9ef69d18 user: drh tags: apply-affinity-first)

15:36
When computing the amount of scratch memory needed during a rebalance operation, assume the worst case for the number of cells per page, rather than relying on the BtPage.nCell value, which might be incorrect for a corrupt database. (check-in: a420ebd0 user: drh tags: trunk)
11:56
Revert the OP_MustBeInt opcode implementation on this branch so that it again matches trunk. The extra functionality is no longer required. (check-in: c02f77b1 user: dan tags: window-functions)
11:35
Tweak the tool/cg_anno.tcl script so that it can run on systems without /usr/bin/tclsh. (check-in: a026189a user: dan tags: trunk)

15:55
Internally, remove all references to a Window object that belongs to an expression in an ORDER BY clause if that expression is converted to an alias of a result-set expression. (check-in: a21ffcd8 user: drh tags: branch-3.27)
15:43
This was originally intended to be the 3.27.2 release, but then I realized that I left out an important patch. (Closed-Leaf check-in: 6c5e5e2e user: drh tags: mistake)

2019-02-23
20:48
Fix a couple of assert() statements in fts3 that can be false if the database is corrupt. (check-in: 84162af5 user: dan tags: trunk)
00:56
Import from trunk the new fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. (check-in: 0e64ac12 user: drh tags: branch-3.27)
00:21
Check-in [fa792714ae62fa98] is incorrect. Add a test case to refute it and also a fix to make it right. Then add an alternative fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. (check-in: d3915230 user: drh tags: trunk)
00:08
Remove a testcase() macro which is now unreachable due to the contraction of the use of IN_INDEX_ROWID. (Closed-Leaf check-in: 90c5a17c user: drh tags: tkt-df46dfb631)
2019-02-22
23:29
Make all ephemeral tables built to hold the RHS of an IN operator be index-btrees, never table-btrees, regardless of whether or not they are used as IN_INDEX_LOOP or IN_INDEX_MEMBERSHIP. That way, the same ephmerial table can be reused for both cases. (check-in: c2d50df8 user: drh tags: tkt-df46dfb631)
21:33
Check-in [fa792714ae62fa980] is not a valid fix for ticket [df46dfb631f75694], as the new test case in this check-in demonstrates. The fix here causes test cases for the [df46dfb631f75694] bug to fail again, so this check-in is on a branch. A new fix is needed for [df46dfb631f75694]. (check-in: 0d456456 user: drh tags: tkt-df46dfb631)
19:24
Internally, remove all references to a Window object that belongs to an expression in an ORDER BY clause if that expression is converted to an alias of a result-set expression. Fix for [4feb3159c6]. (check-in: 579b66ea user: dan tags: trunk)
17:44

16:18
In sqlite3NestedParse() be sure to detect all SQLITE_NOMEM and SQLITE_TOOBIG errors and to distinguish between them. (check-in: 73056b31 user: drh tags: trunk)
15:42
Modify sqlite3_str_finish() and sqlite3VMPrintf() so that they always return NULL on any OOM or SQLITE_LIMIT_LENGTH error. (check-in: e7144ffd user: drh tags: trunk)
2019-02-21
18:11
Fix OOM handling in sqlite3NestedParse(). (Leaf check-in: e6e9dd5c user: dan tags: nested-parse-oom)
16:41
Detect oversized strings in the OP_String opcode even if the P4 argument is originally UTF8 and has to be converted to UTF16 to match the database file and that conversion causes the string to become shorter and cross below SQLITE_LIMIT_LENGTH threshold. This might fix an OSSFuzz problem that we have been so far unable to reproduce. (check-in: c13d5639 user: drh tags: trunk)
2019-02-20
19:20
Changes to the unix VFS that allegedly enable it to build of Fuchsia. We have no way of testing this. (check-in: be21a641 user: drh tags: trunk)
19:06
Disable unix-specific features of dbfuzz2 when compiling on windows. (check-in: af84774d user: drh tags: trunk)

Further test cases and fixes for SQLITE_OPEN_SHARED_SCHEMA. (check-in: ba0ab042 user: dan tags: reuse-schema)
18:13
Avoid the use of function pointers in columnName(), as function pointers appear to be a source of consternation to LLVM. (check-in: c48f6f39 user: drh tags: trunk)
17:36
Add test and fixes for SQLITE_OPEN_SHARED_SCHEMA mode. (check-in: 9a78d89c user: dan tags: reuse-schema)
13:55
Progress handler improvements: (1) Invoke the callback after OP_Program opcodes (2) Invoke the callback multiple times in a row to catch up after a long run of no progress checks. (check-in: 0c5db18d user: drh tags: trunk)
13:23
Merge the latest performance enhancements and fixes from trunk. (check-in: be71d1e2 user: drh tags: apple-osx)

Increment the version number to 3.27.2. (check-in: a70d67d8 user: drh tags: branch-3.27)
13:12
When an IN operator drives a query loop, mark it as "CODED" so that it will not be used afterwards for a (pointless) membership test. (check-in: 55e38d53 user: drh tags: branch-3.27)
12:52
When an IN operator drives a query loop, mark it as "CODED" so that it will not be used afterwards for a (pointless) membership test. This is a better fix for ticket [df46dfb631f75694] than the previous fix that is now on a branch as it preserves the full optimization of check-in [e130319317e76119]. (check-in: fa792714 user: drh tags: trunk)
03:38
Back off the optimization of check-in [e130319317e76119] slightly so that it only applies to IN operators that are used for membership tests. Proposed fix for ticket [df46dfb631f75694]. (Closed-Leaf check-in: b5f90bfe user: drh tags: tkt-df46dfb631)

17:45
Fix a potential memory leak in RBU if the rbu_fossil_delta() SQL function is misused. Misuse never happens in a working RBU system, so this is not a particularly important fix. (check-in: 12517d1b user: drh tags: trunk)
16:42
Fix an assert() that might not be true if the database file is corrupt. (check-in: f2d400db user: drh tags: trunk)

Enhance the virtual table in test_schemapool.c so that it can be used to check that SHARED_SCHEMA connections are not allocating and freeing schemas when they should not be. (check-in: cb236cb9 user: dan tags: reuse-schema)
19:00
Fix a problem with eponymous virtual tables and SHARED_SCHEMA databases. Also, after preparing statements that require all database schemas (REINDEX, ANALYZE, CREATE, DROP and some PRAGMA statements), do not allow the database connection to return more than one schema to each schema-pool. (check-in: ecf6251e user: dan tags: reuse-schema)
11:54
Revert the rearrangement of VDBE code in [219b39e14] so that vdbe.c matches trunk. Since the new call to sqlite3Init() in OP_ParseSchema was removed, the rearrangement no longer provides any performance advantage. (check-in: 03c4f003 user: dan tags: reuse-schema)
2019-02-14

Ensure that the nProgressLimit variable is always initialized in sqlite3VdbeExec(), even if the routine jumps to its exit processing early. (check-in: 167b91df user: drh tags: trunk)
21:04
Enhancement the progress callback mechanism so that the progress callback is always invoked at least once at the end of a prepared statement if the opcode count has been exceeded.

11:04
Avoid using a "return void_function();" statement in void function sqlite3WalSnapshotUnlock(). It provokes a warning from some compilers. (check-in: 4a4952d3 user: dan tags: trunk)
01:58
Add an assert() in an attempt to repro an ASAN warning from OSSFuzz. (check-in: 7b412224 user: drh tags: trunk)
2019-02-09

Fix a page-cache reference leak in the btree balancer when there is a corrupt database. (check-in: 92858991 user: drh tags: deferred-free-space)
21:06
Defer computing the MemPage.nFree value of an in-memory btree page until it is actually needed, since for many pages it is never needed. This checkin works sufficiently to prove the concept, but still has issues with exception handling. (check-in: 1d43ee40 user: drh tags: deferred-free-space)

17:28
Further simplifications to sqlite3VdbeMemSetStr(). (check-in: 1d212957 user: drh tags: trunk)
15:59
Change the sqlite3VdbeMemGrow() routine so that it no longer guarantees a minimum size of 32 bytes. That minimum is no longer required, and without the extra check for the minimum size, the routine runs faster. (check-in: 5c499da8 user: drh tags: trunk)
14:59
Merge the fix for ticket [4e8e4857d32d401f], so that this branch now contains release 3.27.1 plus the extra patch to preserve ROWID values on VACUUM. (check-in: 0cdae60e user: drh tags: apple-osx)
14:55
Give the sqlite3 object a pointer to the current Parse so that if an OOM occurs, it can automatically set the Parse.rc value to SQLITE_NOMEM. This avoids a frequent extra test of db.mallocFailed in the innermost parser loop. (check-in: 5c663804 user: drh tags: trunk)
13:17
Version 3.27.1 (check-in: 0eca3dd3 user: drh tags: release, branch-3.27, version-3.27.1)

Increase the version number to 3.27.1. (check-in: b94d5428 user: drh tags: branch-3.27)
04:15
Do not do the optimization that attempts to pull expression values from an index on that expression when processing a multi-index OR (see check-in [a47efb7c8520a0111]) because the expression transformations that are applied become invalid when the processing moves off of the current index and on to the next index. Fix for ticket [4e8e4857d32d401f]. (check-in: 440a7cda user: drh tags: trunk)
2019-02-07

2019-02-06
20:49
Ensure all bytes of the PgHdr1 structure are initialized. This avoids a valgrind error when running corruptI.test. (check-in: a505e34d user: dan tags: trunk)
20:12
Update an assert() in test_journal.c to take the new "VACUUM INTO" functionality into account. (check-in: 0e6249cb user: dan tags: trunk)
19:42
Avoid attempting to delete a file while it is still open in walfault2.test. (check-in: 9d54a63d user: dan tags: trunk)
18:08
Update test file dbfuzz001.test so that it works with SQLITE_ENABLE_OVERSIZE_CELL_CHECK builds. (check-in: 4371a0c4 user: dan tags: trunk)
15:23
Add -DSQLITE_ENABLE_DESERIALIZE to the default testing configuration in test/releasetest.tcl. (check-in: 433d6ef6 user: dan tags: trunk)

01:18
When extending the size of SrcList objects, do not attempt to use extra space on the end of the allocation, as that provides scarcely any performance benefit but does greatly complicate cross-platform testing. (check-in: 3087a0c3 user: drh tags: trunk)
00:55
If the query flattener detects an error, cause the SELECT code generator to abort immediately. (check-in: 3d3b142f user: drh tags: trunk)
00:11
Back out check-in [008112bcef561a8], reenabling deprecated PRAGMAs when the SQLITE_OMIT_DEPRECATED compile-time option is used, because way too many TH3 tests depend on those deprecated PRAGMAs. (check-in: 9dbf512d user: drh tags: trunk)
2019-02-05
20:51

2019-02-01
21:08
Slight adjustment to the printf formatter large memory allocation detector so that it does not overestimate the amount of space needed for oversize %d conversions. (check-in: 1aee70d6 user: drh tags: trunk)
20:29
Prevent the printf formatter from doing large memory allocations - larger than either the size of the static buffer for interfaces like sqlite3_snprintf(), or larger than SQLITE_LIMIT_LENGTH for interfaces that are associated with a database connection. This helps to prevent DOS attacks on products that let hostile sources inject arbitrary SQL. It also helps fuzzers run faster and more effectively. (check-in: 179e5d46 user: drh tags: trunk)

If the amalgamation file "sqlite3.c" is generated using the SQLITE_ENABLE_UPDATE_DELETE_LIMIT option, but then subsequently (mis-)compiled without that option, and then a particular syntax error could cause a memory leak, but for this fix. (check-in: 1bb17c86 user: drh tags: trunk)
01:39

2019-01-27
19:50
Improvements to the ".eqp trace" command in the CLI so that it ensures that the schema has been read prior to activing the tracing feature, to avoid cluttering the output with a trace of the schema parse. (check-in: 42687d45 user: drh tags: trunk)
02:45
New test cases form dbsqlfuzz (check-in: 9cf8ebd1 user: drh tags: trunk)

2019-01-25
20:09

20:39
Additional steps to help ensure that scalar subqueries are only evaluated once even if they are used in multiple places within the query. This fixes a performance regression reported on the mailing list and caused by check-in [531eca6104e41e43] which was a fix for ticket [787fa716be3a7f650c]. Think of this check-in as an improved fix for that ticket. (check-in: e1303193 user: drh tags: trunk)

Additional small performance increase and size reduction to the sqlite3VdbeMakeLabel() mechanism. (check-in: 1bdee199 user: drh tags: trunk)
02:26
A new implementation of sqlite3VdbeMakeLabel() is faster and makes fewer memory allocations by deferring memory allocation until sqlite3VdbeResolveLabel() is called, at which point the code generator has a better idea of how big the relocation table needs to be. The sqlite3VdbeMakeLabel() routine now takes a Parse* parameter instead of Vdbe*. (check-in: 4a0929ac user: drh tags: trunk)

Simplify the query flattener so that it does not duplicate the WHERE clause of subquery that is being incorporated into the outer query - copies it directly. This is more efficient. And it also fixes the specific test case show for ticket [f09fcd17810f65f71789525] but it does not resolve the more general problem that sqlite3ExprDup() does not correctly duplicate expressions that contain subqueries with window functions.

In order to avoid exporting a symbol, use a macro instead of a function to replace sqlite3_complete() in the shell code when SQLITE_OMIT_COMPLETE is defined. (check-in: d584a0cb user: dan tags: trunk)
13:56
Enhance the xBestIndex interface of virtual table so that if the xBestIndex method returns SQLITE_CONSTRAINT then that particular combination of constraints is considered unusable and does not participate further in query planning. (check-in: 684013ce user: drh tags: trunk)

20:04
When a table is renamed using "ALTER TABLE RENAME TO", update any REFERENCES clauses that refer to the table, unless "PRAGMA legacy_alter_table" is true and "PRAGMA foreign_keys" is set to false (i.e. so that when "PRAGMA legacy_alter_table" is set behaviour is still compatible with versions 3.24 and earlier). (check-in: ae9638e9 user: dan tags: trunk)
18:44
Merge latest trunk changes with this branch. (check-in: ae88f8e1 user: dan tags: reuse-schema)

Update the changesetfuzz program to fuzz changeset schemas as well as data. (check-in: 141a93c8 user: dan tags: changesetfuzz)
19:26
Enable DEFENSIVE mode by default for tests. This requires lots of case of turning DEFENSIVE off in order to dodgy things to the database for testing purposes. No all of those cases are yet handled, so "make test" does not run to completion. (check-in: a1d6c671 user: drh tags: read-only-shadow)
15:57
Turn on defensive mode for running test scripts. Does not yet work. (check-in: 1c1d24ed user: drh tags: read-only-shadow)
14:03
Only allow shadow table to be written from within a recursive SQL call. Omit the SQLITE_PREPARE_SHADOW flag. Some tests are failing because the tests depend on being able to write to shadow tables. (check-in: d890c658 user: drh tags: read-only-shadow)
13:37
Add enforcement of read-only on shadow tables. This does not currently work since some virtual tables are attempting to update shadow tables using sqlite3_exec(). (check-in: f79b47c9 user: drh tags: read-only-shadow)
2018-11-05
23:01
Initial code to make shadow tables read-only to ordinary SQL. The now xShadowName method is added to the sqlite3_module object and is used to identify potential shadow tables. The SQLITE_PREPARE_SHADOW argument to sqlite3_prepare_v3() is defined. It is designed to permit writing to shadow tables, but is currently an unused placeholder. (check-in: 31942b3d user: drh tags: read-only-shadow)

On the first connection to a WAL-mode database that was not cleanly shut down and contains a left-over -shm file, truncate the -shm file to 3 bytes instead of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file. Such a rogue process might think it is being helpful by cleaning up old files, but there is a race condition that can cause damage to the database. (check-in: 90cf32cd user: drh tags: trunk)

Reduce the size of Expr to 64-bytes. This works somewhat, but there are test failures. More importantly, the size reduction from 80- to 64-bytes has not lowered the schema memory usage, but it has made the code a little bigger and a little slower.

Stop requiring the global VFS mutex to access the unixInodeInfo.pUnused field. The unixInodeInfo mutex is sufficient. (check-in: e3ea43da user: drh tags: trunk)
20:46
Take extra precautions to ensure access to unixInodeInfo.pUnused is protected by all necessary mutexes. (check-in: 8b1e0010 user: drh tags: trunk)
17:14
Edit the WHEN and UPDATE OF clauses of trigger programs as part of ALTER TABLE RENAME COLUMN. (check-in: 5fdb6b0a user: dan tags: edit-trigger-wrapper)
17:02
Make the sqlite_rename_column() SQL function resistant to problems caused by OOMs and/or malformed parameters submitted by hostile application code. Also add additional comments to the RENAME COLUMN logic. (check-in: 87743dde user: drh tags: alter-table-rename-column)
15:09
Fix legacy comments on Token. Begin commenting the new ALTER TABLE RENAME COLUMN code. Fix a memory leak in the sqlite_rename_column() SQL function. (check-in: 32edc892 user: drh tags: alter-table-rename-column)
13:43
Fix issues with ALTER TABLE RENAME COLUMN associated with OOM errors. (check-in: 0b28dd5c user: drh tags: alter-table-rename-column)
12:58
Fix a heap-corruption causing race condition in os_unix.c that could occur when one thread wal opening a database file while another is unlocking the same file. Edit: Let's go in a slightly different direction with this fix. (Closed-Leaf check-in: 2447e0fd user: dan tags: unix-lock-fix-attempt)
11:32
Fix an incorrect comment on the unix-nolock VFS object. No functional code changes. (check-in: 90f7c193 user: drh tags: trunk)
2018-08-11
20:46
Add the "atrc" test program. "Atrc" is short for "ALTER TABLE RENAME COLUMN". See the header comment on the program itself for further information. (check-in: ed64a55a user: drh tags: alter-table-rename-column)
20:38
If the new column name in an ALTER TABLE RENAME COLUMN statement is quoted, then also use quotes for the column name in the edited SQL statements. (check-in: ca5184a2 user: dan tags: alter-table-rename-column)
18:34
Avoid an assert() sometimes triggered by ALTER TABLE RENAME COLUMN in non-debug builds. (check-in: 520c1c75 user: dan tags: alter-table-rename-column)
17:49
Fix a bug causing ALTER TABLE RENAME COLUMN to fail when renaming an IPK column that is used in a CHECK constraint. (check-in: 6595c881 user: dan tags: alter-table-rename-column)
17:34
Fix a bug causing all ALTER TABLE RENAME COLUMN commands to fail if ANALYZE had been run on the database. Also prevent the user from renaming the columns of system tables. (check-in: ca644a28 user: dan tags: alter-table-rename-column)
13:40
Reload the entire schema after renaming a column in order to ensure that the schema for any tables for which parent key definitions were changed are reloaded. (check-in: f4497b01 user: dan tags: alter-table-rename-column)
2018-08-10
20:19
Ensure the schema cookie is changed when a column is renamed. (check-in: 2dec9ea4 user: dan tags: alter-table-rename-column)
19:33
Fix harmless compiler warnings. (check-in: 9564d700 user: drh tags: alter-table-rename-column)
19:19
When a column is renamed, update any references to it in REFERENCES clauses that belong to other tables. (check-in: 191079bd user: dan tags: alter-table-rename-column)
15:27
Merge latest trunk changes with this branch. (check-in: c355a837 user: dan tags: alter-table-rename-column)
14:23
Fix a problem with renaming columns on tables with REFERENCES clauses that specify a large number of columns. (check-in: d48f7bbd user: dan tags: alter-table-rename-column)
2018-08-09
21:45
Fix the isLikeOrGlob() routine in the WHERE clause processing logic so that it avoids signed/unsigned character comparisons, as that can lead to an incorrect answer if the ESCAPE clause is an invalid UTF8 string. Problem found by OSSFuzz. (check-in: 4195a3f8 user: drh tags: trunk)
20:47
Experimental implementation of ALTER TABLE ... RENAME COLUMN. Still buggy. (check-in: fa0fc01e user: dan tags: alter-table-rename-column)
18:36
When a column must be a constant due to WHERE clause and the value of that column is being coded as a constant, make sure the affinity is correct. (check-in: 7404ea83 user: drh tags: trunk)
2018-08-08
20:46
Minor style improvements. (check-in: 60bbca2b user: mistachkin tags: trunk)
2018-08-06
17:12
Allow sqlite3_snapshot_open() to be called to change the snapshot after a read transaction is already open on database. (Closed-Leaf check-in: 051ac015 user: dan tags: exp-snapshot-open)
02:08
Enhance the edit() function so that it converts text from \r\n back into \n only if the original unedited copy contained no \r\n values. (check-in: 20c995d3 user: drh tags: trunk)
01:39
Add the --info option to the fuzzcheck test utility. (check-in: 1caaaaa7 user: drh tags: trunk)
01:21
Fix an overzealous assert() statement discovered by OSSFuzz. (check-in: d9c9fe9f user: drh tags: trunk)
2018-08-04
20:30
Remove the column-cache from the code generator. The column-cache has been a persistent source of bugs for years and with recent improvements in the performance of OP_Column, it no longer provides a benefit. After the column cache is removed, the binary is almost 2KB smaller and the speed-check.sh performance test is over 3 million cycles faster. (check-in: cdff3af7 user: drh tags: trunk)
20:12
Remove a testcase() that is no longer reachable without the column cache. Provide an assert() to help prove that the testcase is no longer reachable. (Closed-Leaf check-in: a500893b user: drh tags: omit-column-cache)
17:15
Fix comments that were made obsolete by the removal of the column cache. (check-in: 2041231d user: drh tags: omit-column-cache)
16:54
Remove more column-cache residue: The OP_SetColTab and OP_VerifyColTab opcodes and the associated SQLITE_DEBUG_COLUMNCACHE logic. (check-in: 80236e81 user: drh tags: omit-column-cache)
15:53
Further logic simplifications that flow out of the omission of the column cache. (check-in: 7d9072b0 user: drh tags: omit-column-cache)
15:28
Add test cases for the constant expression fix of the previous check-in. (check-in: 95db5bd9 user: drh tags: trunk)
15:16
Ensure that all expressions that are to be evaluated once at the start of a prepared statement (the Parse.pConstExpr expressions) pass the sqlite3ExprIsConstantNotJoin() test. It is not sufficient to pass just the sqlite3ExprIsConstant() test as that would allow through column references that are bound to constants by the WHERE clause in the constant propagation optimization. This fixes a problem discovered by OSSFuzz. (check-in: 8bc7f84c user: drh tags: trunk)
14:30
Remove additional traces of the column cache. (check-in: db6052e9 user: drh tags: omit-column-cache)
2018-08-03
23:04
Completely remove the column cache logic, which has been a persistent source of bugs for many years. Due to recent enhancements to the performance of the OP_Column opcode, removing the column cache actually makes speed-check.sh run faster. Removing the column cache also saves about 1,800 bytes of code space. (check-in: 3f5f60cd user: drh tags: omit-column-cache)
20:19
Fix the handling of sub-queries with LIMIT clauses by the optimization activated by compile-time symbol SQLITE_COUNTOFVIEW_OPTIMIZATION. (check-in: 21235d9a user: dan tags: trunk)
15:58
Fix the OP_SeekRowid opcode so that it has no type-change side-effects on the key register in P3. This fixes an obcure problem that arises when doing equi-joins between a table with a TEXT column against another table with an INTEGER PRIMARY KEY. The original problem was discovered when OSSFuzz created such a query and hit an assert() in OP_VerifyTabCol that was specifically designed to catch these kinds of errors at run-time. Test cases for this fix are in TH3. (check-in: fa94b49e user: drh tags: trunk)
13:56
Improve "PRAGMA vdbe_trace=ON" to always show the key values for the OP_IdxGT and related opcodes. (check-in: 0f881955 user: drh tags: trunk)
2018-07-29
18:56
In the command-line shell, always exit if realloc() fails. (check-in: e390023c user: drh tags: trunk)
2018-07-28
21:01
Add a small cost penalty to sorting to bias the query planner in favor of plans that do not require a final sorting pass. (check-in: 85b9beb4 user: drh tags: trunk)
16:24
Do not allow a column reference that is converted into a constant by the WHERE-clause constant propagation optimization to be moved to the init-time constant expression list, as the table reference will not work there. This fixes a problem found by OSSFuzz. (check-in: d30b2a94 user: drh tags: trunk)
14:56
Fix an assert() statement that was made obsolete by the constant propagation enhancement. Problem discovered by OSSFuzz. (check-in: e4b4737e user: drh tags: trunk)
14:34
Improved debugging output when the ".selecttrace" option is used in the shell. (check-in: fcb88dd6 user: drh tags: trunk)
13:37
An early attempt at refactoring Expr (Closed-Leaf check-in: fc90a53d user: drh tags: expr-simplify-branch1)
01:30
Add assert() statements to sqlite3ExprDelete() that prove various symmetry properties of the Expr object that might be exploited to make the Expr object smaller and faster. (check-in: 81f25d5c user: drh tags: expr-simplify)
2018-07-27
23:33
Improvements to the parser to increase coverage. Fix the parser so that at least one expresssion is required after PARTITION BY and within the list of expressions on VALUES(). (check-in: 02204f8b user: drh tags: trunk)
22:55
When doing a DROP VIEW do not try to delete entries from the sqlite_stat1 table as there are none. (check-in: 7efdba2b user: drh tags: trunk)
22:14
Minor grammar changes that help the parser run faster by reducing the number of NUL rule reductions. (check-in: cfd1b005 user: drh tags: trunk)
20:45
Enhance Makefile for MSVC to support building the shell tool without using the amalgamation. (check-in: 3d815d83 user: mistachkin tags: trunk)
20:37
The WHERE-clause constant propagation optimization attempts to use transitive laws to replace column values with constants in the WHERE clause in order to help to query planner make more aggressive optimizations. (check-in: f4229707 user: drh tags: trunk)
20:01
Reduce the performance cost of the constant propagation optimization to less than 200,000 cycles. (Closed-Leaf check-in: 865249de user: drh tags: propagate-const-opt)
18:19
Performance improvement to sqlite3ExprCollSeq(). With this change, the performance of speed-check.sh is within 400,000 cycles of trunk. (check-in: a5f86f49 user: drh tags: propagate-const-opt)
18:12
Faster implementation of sqlite3IsBinary(). (check-in: be05d0db user: drh tags: propagate-const-opt)
17:51
Only run the constant propagation optimization on joins since that is the only scenario where it is useful. This saves prepare time for the common case of a simple query. (check-in: 598d6083 user: drh tags: propagate-const-opt)
16:57
Constant propagation is now restricted to just the WHERE clause. The mechanism is changed to take affinity and collation into account. This seems to give correct answers. But the search for constant propagation costs 4 million cycles in the speed test. (check-in: 82c67efb user: drh tags: propagate-const-opt)
2018-07-26
23:54
Add a test case demonstrating the collation problem with constant propagation. (check-in: 50add839 user: drh tags: propagate-const-opt)
23:47
Generalize the constant propagation optimization so that it applies on every WHERE close, not just those that contain a subquery. This then demonstrates that the current implementation is inadequate since it does not take into account collating sequences. (check-in: 57eb2abd user: drh tags: propagate-const-opt)
21:48
In the unix VFS, give every unixInodeInfo object its own mutex, rather than using the global VFS mutex, to improve concurrency in cases where there are many threads operating on separate database files. (check-in: 22f47cf4 user: drh tags: trunk)
21:16
Initial implementation of the WHERE-clause constant propagation optimization. (check-in: 2fb82ad8 user: drh tags: propagate-const-opt)

Fix a typo in the documentation for sqlite3_snapshot_get(). (check-in: cd9713c9 user: dan tags: trunk)
2018-07-24
22:02
Do not abort running queries due to a CREATE INDEX statement. Allow them to run to completion before being reprepared. Fix for ticket [c694113e50321afdf9]. (check-in: 2bd59333 user: drh tags: trunk)
13:57
Add missing SQLITE_OMIT_WINDOWFUNC check to the json1 extension. (check-in: fe19f823 user: mistachkin tags: trunk)
2018-07-23

Return an SQLITE_NOMEM error if the locking mutex fails to allocate. (Closed-Leaf check-in: 1c948348 user: drh tags: separate-lock-mutex)
21:10
First attempt at reducing mutex contention in the unix VFS by providing a separate mutex for each unixInodeInfo object. (check-in: f69afaf0 user: drh tags: separate-lock-mutex)
18:53
Fix typo of 'SQLITE_OMIT_WINDOWFUNC'. (check-in: 8607b84a user: mistachkin tags: trunk)

Attempt to improve the documentation for snapshots. No changes to code. (check-in: 46dd076a user: drh tags: trunk)
10:57
Fix the macros used to generate the output of "PRAGMA compile_options" so that they handle valid values for the SQLITE_DEFAULT_LOOKASIDE macro (which contain a "," character). (check-in: 1cc72845 user: dan tags: trunk)
2018-07-22
21:23
Fix more harmless compiler warnings seen with MSVC. (check-in: edab5666 user: mistachkin tags: trunk)

In 'resetdb.test', close a database prior to trying to delete it. (check-in: 45137053 user: mistachkin tags: trunk)
2018-07-20
20:56
When dropping a view, skip trying to delete from 'sqlite_stat*'. (check-in: 2f5be3a2 user: mistachkin tags: dropViewNoStat)
19:24
Change the SQLITE_Stat34 bit of the optimization test-control so that it prevents STAT4 data from being used but allows it to be loaded into the Index objects. This permits STAT4 to be turned on and off on a per-statement basis. (check-in: 489f3caf user: drh tags: trunk)
18:01
Experimental change to ANALYZE so that when computing values for sqlite_stat1, it uses the maximum number for the number of rows having equivalent values, rather than the average. (Leaf check-in: 085f17e1 user: drh tags: stat1-max)
15:44
New checks in PRAGMA integrity_check to validate the autovacuum settings in the header. (check-in: a4663f09 user: drh tags: trunk)
13:39
Enhanced detection of problems on the freelist and on overflow list in PRAGMA integrity_check. (check-in: 11e58f5b user: drh tags: trunk)
2018-07-19
15:27
Avoid a branch in the commit logic that is unreachable when compiled without SQLITE_ENABLE_BATCH_ATOMIC_WRITE. (check-in: 271b8980 user: drh tags: trunk)
14:40
Allow the VACUUM following SQLITE_DBCONFIG_RESET_DATABASE to proceed even if the write-version in the header indicates that the database file is not writable. (check-in: 3dca8b9d user: drh tags: trunk)
11:44
Experimental fix for resetting databases that have been deemed read-only due to a corrupt "read-version" header field. (Closed-Leaf check-in: e2394002 user: dan tags: exp-dbreset-fix)
2018-07-18
19:09
Add the SQLITE_FCNTL_DATA_VERSION file control (check-in: a5087c5c user: drh tags: trunk)
17:37
Fix a harmless compiler warning in the pager. Enhance the docs for sqlite3_changes() and sqlite3_total_changes() to refer to the data_version pragma. (check-in: 4c70ea5b user: drh tags: trunk)

2018-07-11
13:34
On an UPSERT when the order of constraint checks is rearranged, make sure that the affinity transformations on the inserted content occur before any of the constraint checks. Fix for ticket [79cad5e4b2e219dd197242e9e5f4e]. (check-in: d120c45f user: drh tags: trunk)

Adjustments to VdbeCoverage macros to deal with byte-code branches that can never be taken in some directions. (check-in: b170c009 user: drh tags: trunk)
2018-07-10
23:31
Remove incorrect ALWAYS() macros from the window function logic. (check-in: 94ac51cc user: drh tags: trunk)
22:24
Add VdbeModuleComment()s on the three main code generators for window functions. (check-in: f7c239e9 user: drh tags: trunk)
20:50
Minor comment changes. Add ALWAYS() macros on some unreachable branches in the xStep() methods of built-in window functions. (check-in: f2057542 user: drh tags: trunk)
19:48
Identify Select objects within a single statement using small sequential integers rather than "0x%p". This is more readable and yields the same result on successive runs. (check-in: a7cdc5bc user: drh tags: trunk)
18:50
Modify tests in window3.test to be tolerant of rounding errors when comparing floating point values. (check-in: 7c26c443 user: dan tags: trunk)
17:26
Fix a problem with using scalar sub-selects in window function queries. (check-in: 687fe532 user: dan tags: trunk)
17:10
Further improvements to bytecode branch testing. Fix cases where the macros said a branch could not be taken when in fact it could be. Alter some window function branch coverage macros to indicate that comparison operands cannot be NULL. (check-in: 76e42b70 user: drh tags: trunk)
16:04
Enhancements and improved documentation to the byte-code branch coverage testing logic. Provide new macros that allow the code to specify that some branch instructions can never take the NULL path and that the OP_Jump opcode is only interested in equal/not-equal. The SQLITE_TESTCTRL_VDBE_COVERAGE file control callback now works slightly differently (it provides the callback with a bitmask of the branch action, rather than an integer). (check-in: cd2da7e1 user: drh tags: trunk)
15:55
Experimental planner change to avoid a skip-scan if a regular index scan on the same index columns can be done instead. (Leaf check-in: 350f29ea user: dan tags: exp-begin-concurrent-pnu)

Merge latest trunk changes into this branch. (check-in: e9a3e864 user: dan tags: begin-concurrent)
07:39
Fix a harmless warning about comment formatting in the previous check-in. Simplify the ORDER BY dereferencing logic so that it avoids unreachable branches. (check-in: 0f6ec605 user: drh tags: trunk)
07:25
Assert that if two functions compare equal in every other way, then they must both have OVER clauses, or neither has an OVER clause. Use this fact to simplify expression comparison. (check-in: 52559ad5 user: drh tags: trunk)
06:47
Enhance the sqlite3ExprCompare() routine so that it knows to compare the OVER clause of window functions. (check-in: 0a7649af user: drh tags: trunk)
06:32
Enhance the TreeView mechanism so that it shows the window function data structures as part of the abstract syntax tree. (check-in: a2c0e1be user: drh tags: trunk)

Fixes for various harmless compiler warnings. (check-in: 5023b1b8 user: drh tags: trunk)
20:58
Add a comment to restriction (6) of the push-down optimization. No changes to code. (check-in: 0c8a2f25 user: drh tags: trunk)
20:41
Add an ALWAYS() around a branch in sqlite3BtreeSkipNext() that we believe must always be true. (check-in: 12be361a user: drh tags: trunk)
18:55
Avoid leaving view-definitions with an incomplete set of column names/types in the in-memory schema if an OOM strikes while allocating the same. (check-in: 1ddbb537 user: dan tags: trunk)
18:11
Add a couple of OOM tests. (check-in: 50de2a0d user: dan tags: trunk)
17:33
Remove redundant branches in window function processing. (check-in: 8fdaf3f3 user: drh tags: trunk)
16:24
Simplification to the grammar rules for window functions. Fix a memory leak that can follow an OOM while parsing a comma-separated list of window definitions. (check-in: a568f9c9 user: drh tags: trunk)
13:31
Throw an error if the second argument passed to nth_value() is not a positive integer. (check-in: 1a06e57a user: dan tags: trunk)
06:51
Fix a bad assert() in window.c. (check-in: fe8aaf0c user: dan tags: trunk)
02:37
Simplification to the logic that detects misuse of the application-defined function creation interfaces. (check-in: 8f21d778 user: drh tags: trunk)
02:02
During WITHOUT ROWID table creation, if the sqlite3CreateTable() call fails due to an authorizer denying the INSERT into the sqlite_master table, then detect this fact and abort the CREATE TABLE early, to avoid an assertion fault. (check-in: 164b1641 user: drh tags: trunk)
2018-07-08
01:02
Identify specific FuncDef objects for window functions using the pointer to the function name (FuncDef.zName) rather than the pointer to the xStep method. This allows xStep method pointer to be replaced with a single noopStepFunc() procedure, and thus save having lots of different no-op step functions. (check-in: 410e13b0 user: drh tags: trunk)
2018-07-07
20:55
Simplifications to the implementation of the sum() SQL function. (check-in: a8b13002 user: drh tags: trunk)

Avoid invoking the whereLoopAddOr() routine in the query planner if there are no OR operators in the WHERE clause, thus speeding up query planning slightly. (check-in: 292724ff user: drh tags: trunk)
2018-06-08
23:23
When the query planner has the opportunity to use an IN operater constraint on a term of an index other than the left-most term, use the estimated number of elements on the right-hand side of the IN operator to determine if makes sense to use the IN operator with index lookups, or to just do a scan over the range of the table identified by the index terms to the left. Only do this if sqlite_stat1 measurements are available as otherwise the performance estimates will not be accurate enough to discern the best plan. Bias the decision slightly in favor of using index lookups on each element of the IN operator. (check-in: 2cbbabdf user: drh tags: trunk)
21:21
Only choose to scan an IN operator rather than use an index if we have real STAT1 data to suggest it is advantageous. (Closed-Leaf check-in: 30e87466 user: drh tags: in-scan-vs-index)

18:13
The IN-early-out optimization: When doing a look-up on a multi-column index and an IN operator is used on a column other than the left-most column, then if no rows match against the first IN value, check to make sure there exist rows that match the columns to the right before continuing with the next IN value. (check-in: 09fffbdf user: drh tags: trunk)

Attempt to optimize the resolveExprStep() routine by mapping Expr opcodes into a subset of opcodes that resolveExprStep() cares about and only calling the routine when those opcodes are encountered. Is slightly faster, but it seems like the very slight performance bump is not worth the added complexity. Saved on a dead-end branch for historical reference.

Demonstration code on a possible technique for optimizing the use of IN operator on columns to the right of multicolumn indexes.

13:07
Enhance the CLI to render EXPLAIN QUERY PLAN using an ASCII-art graph. This works with ".eqp" modes and when the query begins with exactly "EXPLAIN QUERY PLAN".

Optimize calls to sqlite3_mprintf("%z...") so that they attempt to append text onto the end of the existing memory allocation rather than reallocating and copying. (check-in: 4bc8a48e user: drh tags: trunk)
13:46
Remove a lot of the text describing extended format options from the documentation on sqlite3_mprintf() and friends, since that information is now covered by the separate printf.html document. Provide links to that other document. No changes to code. (check-in: 99eec556 user: drh tags: trunk)

22:46
Enhance the string formatter (used by printf()) so that the width and precision of string substitution operators refer to characters instead of bytes when the alternate-form-2 flag ("!") is used. Also fix the %c substition to always work within unicode, regardless of the alternate-form-2 flag. (check-in: c883c4d3 user: drh tags: trunk)
21:58
Printing a value of 0 using %c terminates the string. (Closed-Leaf check-in: 255612f0 user: drh tags: printf-enhancement)

18:03
Make the alternate-form-2 flag ("!") change the meaning of width and precision from bytes to characters for the %q, %Q, and %w extensions of printf(). (check-in: 391540ac user: drh tags: printf-enhancement)
17:03
In the printf() library, measure width and precision in characters rather than bytes if the "!" (alternate-form-2) flag is present on a %s or %z substitution. (check-in: ca31c663 user: drh tags: printf-enhancement)
16:34
Only try to use the geteuid() interface on unix if HAVE_FCHOWN is defined. This fixes the build for vxWorks, we are told. (check-in: 38f654dc user: drh tags: trunk)

Modify the zonefile format in order to avoid depending on the filesize to determine the extent of the final frame. See README.md for details. (check-in: 4dbe0cba user: dan tags: zonefile)
13:53
Fix an assert so that it compares two CellInfo objects field by field instead of using memcmp(). Memcmp() does not work on x86 because of uninitialized padding bytes. (check-in: 88258770 user: drh tags: trunk)
2018-02-18
17:50
Fix a memory leak in the processing of nested row values. This problem has existed every since row values support was added (version 3.15.0, 2016-10-14) but was only just now detected by OSSFuzz. (check-in: 2df6bbf1 user: drh tags: trunk)

Add support for zlib compression to the zonefile module. (check-in: 72b8a7ef user: dan tags: zonefile)
20:00
On unix, the "PRAGMA fsync_interval=N" command causes an extra fdatasync() after writing N bytes of content, to force a write-queue flush in the underlying OS. This is an experimental hack that is not expected to land on trunk. (Leaf check-in: b18cc5fe user: drh tags: write-queue-flush-hack)

Fix another point in zonefile.c so that all files are opened in either "rb" or "wb" mode. (check-in: fb1c2277 user: dan tags: zonefile)
15:17
When calling fopen() in the zonefile extension, use modes "rb" and "wb" instead of "r" and "w". This makes no difference on unix, but is required when accessing binary files on other systems. (check-in: 4bb854dd user: dan tags: zonefile)

2018-02-09
23:25
Improve the performance of the built-in REPLACE() function in cases where it does many substitutions that make the string larger. OSSFuzz is reporting intermittant timeouts when running a test where it does a REPLACE() on a 930KB random blob. Perhaps this enhancement will fix that. (check-in: fab2c2b0 user: drh tags: trunk)

18:02
In extensions rtree, fts3 and fts5, ensure that when dynamic buffers are bound to persistent SQL statements using SQLITE_STATIC, the binding is replaced with an SQL NULL before the buffer is freed. Otherwise, a user may obtain a pointer to the persistent statement using sqlite3_next_stmt() and attempt to access the freed buffer using sqlite3_expanded_sql() or similar.

Remove the time() dependency from the zipfile extension. Use SQLite VFS methods instead. (check-in: 0702fb56 user: dan tags: trunk)
08:14
In SQLITE_ENABLE_BATCH_ATOMIC_WRITE builds on F2FS file-systems, invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE if an SQLITE_FCNTL_COMMIT_ATOMIC_WRITE call fails. Also, do not use an atomic transaction to create the initial database. This is because if an error occurs while writing to the db file, any changes to the file-size do not seem to be rolled back automatically. The only time this matters is when the file was 0 bytes in size to start with. Cherrypick of [b3122db154]. (check-in: 22a228ed user: dan tags: branch-3.19)

In the 'fileio' extension code for Win32, use the FILE_FLAG_BACKUP_SEMANTICS flag when setting the file times, just in case the file is actually a directory. (check-in: 4f344406 user: mistachkin tags: sqlar-shell-support)
22:50
Remove 'timespec' related code from the shell that has no effect and a (now) superfluous 'timespec' typedef from the Win32 dirent header file. (check-in: 57dac995 user: mistachkin tags: sqlar-shell-support)

Replace the sqlite3_memdb_ptr() interface with the more general sqlite3_serialize() interface. (check-in: 8cf2ed4e user: drh tags: memdb)
13:20
Simplify the "sqlite3" command in the TCL interface. The filename is now optional. There is a new --memdb option with an argument that is the blob to which the database content should be initialized. (check-in: 47398ae7 user: drh tags: memdb)
12:39
Fix typo in the Makefile for MSVC. (check-in: e5c6ade8 user: mistachkin tags: memdb)

Add another test case (found by OSSFuzz) for the problem fixed in check-in [2846458a] and described by ticket [dc3f932f5a147771]. No changes to code. (check-in: 4165fae9 user: drh tags: trunk)
01:28
Add support for the "memdb" VFS and the sqlite3_memdb_ptr() and sqlite3_memdb_config() interfaces, to enable an SQLite database to be manipulated as an in-memory object. (check-in: fb2ac2d2 user: drh tags: memdb)
2018-01-02

12:50
Do not attempt to use pragma_module_list in the command-line shell unless it has been compiled with -DSQLITE_INTROSPECTION_PRAGMAS. (check-in: 39ca5fcd user: drh tags: trunk)
00:04
The ".schema" command in the command-line shell now shows the structure of table-valued functions and eponymous virtual tables if they are named on the ".schema" command line. Example: ".schema sql%" shows the structure of the "sqlite_dbstat" and "sqlite_stmt" virtual tables. (check-in: f80f6651 user: drh tags: trunk)
2018-01-01
21:49

Have zipfile support DELETE commands. (check-in: 01d4e866 user: dan tags: sqlar-shell-support)
14:26
Rearrange things a bit so that writing to a zipfile does not invert the order of objects it contains. (check-in: f69e8194 user: dan tags: sqlar-shell-support)
2017-12-29
20:19
Update ext/misc/zipfile.c to support creating and adding entries to existing zip archives. (check-in: 2dec2dec user: dan tags: sqlar-shell-support)
17:21

16:37
Stricter test cases. (Closed-Leaf check-in: 9406c0a6 user: drh tags: location-function)
15:19
Fix a typo in the MSVC makefile. (check-in: 89e5720a user: drh tags: location-function)
15:04
Change the function name to sqlite_unsupported_offset(X). Only enable the function if compiled with -DSQLITE_ENABLE_OFFSET_SQL_FUNC. The makefiles add that definition to shell builds. (check-in: 7a7f826e user: drh tags: location-function)
14:33
Enhance location(X) so that it works with indexes and WITHOUT ROWID tables. The function might return an offset to the main table or to an index, depending on whether the column X would be loaded from the main table or from the index. (check-in: dd94d6a8 user: drh tags: location-function)
13:35
Merge recent enhancements from trunk. (check-in: 6251e438 user: drh tags: location-function)

2017-12-27
22:09
The output of sqlite3_trace() now shows each command of a trigger as it is evaluated. This feature involved major changes to the parser, such as removing the ExprSpan object and replacing it with a new mechanism for capturing the original SQL text of phrases in the input SQL. (check-in: 0fdf97ef user: drh tags: trunk)
21:30
Omit all sqlite3_trace() output from the triggers associated with foreign key constraints. (Closed-Leaf check-in: fda08e3d user: drh tags: span-refactor)

Merge recent enhancements from trunk. (check-in: 76373091 user: drh tags: span-refactor)
18:54
Have the shell tool ".ar --list" and ".ar --extract" commands support zip files. Currently the "-zip" switch is required. (check-in: a532a0f6 user: dan tags: sqlar-shell-support)
18:19
Enhance the Lemon parser generator so that it creates a faster parser at the cost of slightly larger parser tables. Add the ability to measure coverage of the generated state machine when compiling with the -DYYCONVERGE option. In SQLite, add the SQLITE_TESTCTRL_PARSER_COVERAGE test-control to query the new parser coverage feature. (check-in: 1b22b42e user: drh tags: trunk)
17:36
The previous check-in had an error in the coverage reporting logic. (Closed-Leaf check-in: ec9b19eb user: drh tags: lemon-improvements)
17:14
Change the coverage measurement logic in the lemon-generated parser so that it only checks for coverage of state/lookahead pairs that are valid syntax. It turns out that some states are unreachable if the lookahead is not valid syntax, because the states are only reachable through a shift following a reduce, and the reduce does not happen if the lookahead is a syntax error. (check-in: 9dce4650 user: drh tags: lemon-improvements)
16:13
In the lemon-generated parser, do not report the End-of-input character and the wildcard character as missed coverage. (check-in: 3fe96487 user: drh tags: lemon-improvements)
15:21
In LEMON, fix an off-by-one error that can make the lookahead table one byte too smal. (check-in: 93792bc5 user: drh tags: lemon-improvements)
2017-12-26
20:39
Add new file ext/misc/zipfile.c, containing a virtual table for read-only access to simple zip archives. (check-in: 8e366b99 user: dan tags: sqlar-shell-support)
18:32
Change the lemon-parser coverage report format to report all state/lookahead pairs and indicate on each whether it is hit or missed. (check-in: 86e30fc2 user: drh tags: lemon-improvements)
18:14
Merge bug fixes from trunk. (check-in: d76e1206 user: drh tags: lemon-improvements)
18:04
Add support for measuring and reporting coverage of the parser state machine using the SQLITE_TESTCTRL_PARSER_COVERAGE test-control. (check-in: 1253a872 user: drh tags: lemon-improvements)
14:46
Faster and smaller implementation of sqlite3AtoF() based on a suggestion from Cezary H. Noweta. (check-in: fd2e0e7a user: drh tags: trunk)
14:32

Fix crashes that could occur if SQL NULL values were passed to the built-in FTS5 snippet function. Edit: breaks amalgamation builds. (check-in: 553a3ad3 user: dan tags: mistake)
2017-12-25
13:43
Fix an assertion fault on a syntax error input caused by check-in [6b2ff26c25bb9da3]. Problem discovered by OSSFuzz. (check-in: 90d6e4f1 user: drh tags: trunk)
04:15
Enhance LEMON so that it generates the action table in such a way that no range check is needed on the lookahead table to verify that the next input token is valid. This makes the lookahead table slightly larger (about 120 bytes) but helps the parser to run faster. (check-in: 7eb0198d user: drh tags: lemon-improvements)
00:10
In the LEMON-generated parser, avoid unnecessary tests for the acceptance state. (check-in: fdbb35c5 user: drh tags: lemon-improvements)
2017-12-24
23:38
In the LEMON-generated parser, rearrange the meanings of integer action codes so that reduce actions occur last. This means that the most common case (reduce actions) can be recognized with a single comparison operation, thus speeding up the main parser loop, slightly. (check-in: 7bfe7a36 user: drh tags: lemon-improvements)
18:56
Fix a NULL pointer dereference after a syntax error that can occur as a result of check-in [6b2ff26c25bb9da3] yesterday. This problem was discovered by the OSSFuzz. (check-in: d49afb8f user: drh tags: trunk)
17:06
Improved parser tracing output. (check-in: 25be5750 user: drh tags: lemon-improvements)
17:01
Grammar changes: the sclp non-terminal should always be followed by a scanpt. (check-in: 74a0181f user: drh tags: span-refactor)
14:14
Improved parser tracing output. (check-in: c4951833 user: drh tags: span-refactor)
00:18
Remove the ExprSpan object. Instead, keep track of the test of subphrases in the parse using the "scanpt" non-terminal. (check-in: 3eab7bdc user: drh tags: span-refactor)

13:55
Improve the error message that comes back when sqlite3_load_extension() fails because the named file exists but is not a valid shared library. (check-in: 05fee1a2 user: drh tags: trunk)
12:33
Move the generation of output column names earlier in the case of a CREATE TABLE AS. This is a fix for ticket [3b4450072511e62] and a continuation of check-in [ade7ddf1998190b2b63] that fixes cases of ticket [de3403bf5ae5f72ed6] that were missed previously. (check-in: 6b2ff26c user: drh tags: trunk)
11:51
Add a SELECTTRACE() macro to indicate when column names are assigned to a SELECT statement. This helps with debugging for tickets like [de3403bf5ae5f72e] and [3b4450072511e621]. (check-in: 8f194008 user: drh tags: trunk)
2017-12-22
19:53
In the sqlite3TreeViewExprList() routine, show the "AS" alias name for each expression in the list, if it exists. (check-in: 5efd854f user: drh tags: trunk)
00:52
Modify the new sqlite3_vtab_collation() interface so that it takes a pointer to the sqlite3_index_info object passed into xBestIndex rather than an sqlite3 connection pointer, which the xBestIndex method might not have access to. (check-in: 5c1fe666 user: drh tags: trunk)
2017-12-21
21:41
Fix SQLITE_DBCONFIG_TRIGGER_EQP so that it works even if SQLITE_DEBUG is not defined. (check-in: afbbfff7 user: drh tags: trunk)
21:02
Add the ".eqp trigger" option to the ".eqp" command in the command-line shell. Implemented using the new SQLITE_DBCONFIG_TRIGGER_EQP control. (check-in: 2c51644a user: drh tags: trunk)
18:55
Add the ".expert" command to the shell tool's ".help" output. (check-in: fc6193af user: dan tags: trunk)
18:23
Change the name of SQLITE_DBCONFIG_FULL_EQP to be SQLITE_DBCONFIG_TRIGGER_EQP (which we can do without breaking compatibility because the former name has not yet appeared in an official release) and streamline its implementation. (check-in: fffc7685 user: drh tags: trunk)
14:46
Add the SQLITE_DBCONFIG_MAX preprocessor macro which will always be equal to the largest SQLITE_DECONFIG value. (check-in: 95d41033 user: drh tags: trunk)
02:17
Add the experimental ".expert" command to the sqlite3.exe shell. (check-in: 0821bae7 user: drh tags: trunk)
2017-12-20

Experimentally add the SQLite expert functionality to the shell tool. (Closed-Leaf check-in: 51068dba user: dan tags: expert-in-shell)
2017-12-16
20:20
Add an experimental location(X) SQL function that attempt to return the location of the payload within the database for the record that contains column X. location(X) returns NULL if X is not an ordinary table column or if SQLite cannot figure out the location because it is using a covering index. (check-in: 51be9558 user: drh tags: location-function)
19:36
Add the sqlite3_vtab_collation() function, which allows an xBestIndex callback to determine the collation sequence that SQLite will use for a comparison. And the SQLITE_DBCONFIG_FULL_EQP configuration option, which enhances the output of "EXPLAIN QUERY PLAN" so that it includes statements run by triggers. And the code for the sqlite3_expert extension and command line application. (check-in: 4c782c95 user: dan tags: trunk)
19:16
Merge latest trunk changes into this branch. (Closed-Leaf check-in: d5b597b5 user: dan tags: schemalint)
19:11
Do not use the compress() and uncompress() functions in ext/misc/compress.c - they are not quite compatible with the spec. Instead use new functions in ext/misc/sqlar.c. (check-in: 7652b3c2 user: dan tags: sqlar-shell-support)
04:37
Add unnecessary initializations to some local variables in the rtree module to suppress false-positive compiler warnings coming out of MSVC. (check-in: 64487d65 user: drh tags: trunk)
2017-12-15

An improved way of generating the SQLITE_READONLY_DIRECTORY error. The error message submitted to sqlite3_log() is still correct this way. (check-in: 1c0aa919 user: drh tags: trunk)
20:17
Add the shell tool ".ar --update" command. (check-in: 825e3c03 user: dan tags: sqlar-shell-support)
20:04
Add support for the "--list" command. And for arguments to the "--extract" command. (check-in: 32c4fa25 user: dan tags: sqlar-shell-support)
20:02
New result code SQLITE_READONLY_DIRECTORY is returned when an attempt is made to write on a database file that is in a read-only directory and hence the journal file could not be created. This situation formerly returned SQLITE_CANTOPEN, which less helpful. (check-in: 3ec73c38 user: drh tags: trunk)
18:01
Correctly invalidate a column cache line when it is overwritten with NULL. Fix for ticket [123c9ba32130a6c9d432]. (check-in: 65754dc3 user: drh tags: trunk)
15:32
Change some LSM code internal typenames from "Blob" and "Pgno" to "LsmBlob" and "LsmPgno". This allows the LSM code to be compiled as a single unit with sqlite3.c. (check-in: 30bf38d5 user: dan tags: trunk)
14:22
Add script to amalgamate all LSM files into "lsm1.c". (check-in: e32b69d7 user: dan tags: trunk)

Increase the version number for the next release - which is still months away but there have been significant query planner enhancements since the previous release. (check-in: 457eedfa user: drh tags: trunk)
20:51
Reactivate query flattening when the result set of the outer query has no function calls or subqueries. This is a partial reversal of check-in [c9104b59]. Co-routines are still preferred if the outer query has a complex result set, but for simple results sets, query flattening is used. Check-in [4464f40ccd7] is completely backed out due to this change. (check-in: d17ef7d1 user: drh tags: trunk)

2017-10-27
23:28
I was a little concerned about this check-in. Though I could not generate a failure myself, I thought it was risky. I checked it in for further testing. Then, overnight, OSSFuzz found a failure case for me. So the change is now moved out into a deadend branch. Was: Use OP_SCopy rather than OP_Copy to transfer results from a co-routine to its consumer. This undoes an earlier fix for ticket [98825a79ce] by check-in [ec6a06246e] because that problem no longer occurs due to WHERE clause push-down. (Closed-Leaf check-in: 0926df09 user: drh tags: mistake)

11:09
Cherrypick [ec37ad6d08] into this branch. With this patch, if SQLITE_SHARED_MAPPING is defined at build-time SQLite will use a single memory mapping for multiple connections to the same database file within a single process. (check-in: c7a5880d user: dan tags: begin-concurrent)
10:49

20:43
In the Windows VFS, when trying to open a database file read/write, if it fails check to see if the file exists and is read-only and immediately fall back to a read-only open attempt, rather than running the AV retry loop. (check-in: 5d03c738 user: drh tags: trunk)
20:03
In the Windows VFS, do not emit an SQLITE_CANTOPEN error log message when falling back from SQLITE_OPEN_READWRITE to SQLITE_OPEN_READONLY. Wait until the open fails completely. (check-in: fa3f5bcc user: drh tags: trunk)

10:24
Fix a bug in tool/mksourceid.c: The mksourceid.c program was incorrectly including the "# Remove this line" line of the Fossil-generated "manifest" file in the SHA3 hash. That means that all SQLITE_SOURCE_IDs for trunk versions going back to check-in [30966d56] (2017-08-22) are incorrect. (check-in: 65765222 user: drh tags: trunk)

19:45
Do not make the assumption (as check-in [4da49a95c0f07] incorrectly did) that the ExprList returned by sqlite3ExprListDup() would never be passed into sqlite3ExprListAppend(). Include a new test case that shows this sometimes does happen. (check-in: 29227d00 user: drh tags: trunk)

2017-07-30
20:30
Correctly handle an "INTEGER PRIMARY KEY UNIQUE" column in a WITHOUT ROWID table. This is a fix for ticket [bc115541132dad136] cherry-picked from [5216bfb73f1a49bdd]. (check-in: 5c8cb1ff user: drh tags: branch-3.20)

17:01
Update test program "tserver" to use a native pthreads mutex/condition variable to efficiently manage wal file checkpoints without the wal file growing indefinitely. (check-in: 8299bdb7 user: dan tags: server-process-edition)
16:01
Move the generation of output column names earlier, to right after name resolution and before query transformations such as flattening. This prevents the names from getting mangled by query transformations, and obviates hacks in the query flattener that attempt to work around the name mangling. The resulting code is smaller and faster and gives more consistent output. This is an alternative fix to ticket [de3403bf5ae5f72ed]. (check-in: 09834279 user: drh tags: early-column-names)
14:56
Use the subquery column name, not the original SQL statement text, as the added AS clause in the query flattener. (Closed-Leaf check-in: 5df7f0e6 user: drh tags: flattener-column-names)
03:33
In the query flattener, only add AS clauses to output columns of the outer query that are copied directly from the inner query. Formerly, all columns of the outer query received an AS clause if they did not have one already. This is a proposed fix for ticket [de3403bf5ae5f72].

21:06
Make the freelist format a separate feature from the page-level locking. Freelist format is now configure using "PRAGMA freelist_format". (check-in: dcc40797 user: dan tags: server-process-edition)
20:11
Fix documentation typo. No changes to code. (check-in: 9319f7b7 user: drh tags: trunk)
19:11
Update header comments on the carray() and remember() extensions to bring out the fact that the pointer arguments must be bound using sqlite3_bind_pointer(). (check-in: 55f53965 user: drh tags: trunk)
18:09
Add new interfaces sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer() used to safely move pointer values through SQL without exposing underlying memory address information. (check-in: 72de49f2 user: drh tags: trunk)
17:56
Fix an incorrect type signature for the loadable extension pointer for sqlite3_result_pointer(). (Closed-Leaf check-in: 0bd7875b user: drh tags: bind-pointer)
17:54
Add the three new pointer interfaces to the loadable extension mechanism. Update sqlite3_value_subtype() documentation to remove the statement about it not being used internally. (check-in: e5a51803 user: drh tags: bind-pointer)
17:48
Update the FTS3 extension to use sqlite3_result_pointer() and sqlite3_value_pointer() for passing FTS3 cursor objects from the table into functions such as snippet(). (check-in: 0fa2e170 user: drh tags: bind-pointer)
17:34

Smaller and faster implementation for vdbeFreeOpArray() and freeP4(). (check-in: 0c805935 user: drh tags: trunk)
18:05
Fix harmless compiler warnings about incomplete structure initializers. (check-in: 604c11d1 user: drh tags: trunk)
17:26
Remove unnecessary EP_Leaf settings on the Expr object. (check-in: f951c8b7 user: drh tags: trunk)
17:08
The EP_Resolved flag on the Expr object is not required for correctness nor performance, so remove it. (check-in: 54f55d3b user: drh tags: trunk)
14:10
Clarification and simplification and result column naming logic. (check-in: 68824a43 user: drh tags: trunk)

Compile cleanly with SQLITE_OMIT_UTF16. (check-in: 783100b8 user: drh tags: trunk)
2017-07-11
20:36
In lsm, attempt to unmap the database file before truncating it when disconnecting. A mapped file may not be truncated on win32. (check-in: 39069941 user: dan tags: trunk)
19:55
Simplify the way in which the database file is truncated when the last connection disconnects. Also ignore the error code from the xTruncate call - as truncating a database file is always optional. (check-in: b0a49d90 user: dan tags: trunk)
18:38
Add SQL function usleep() to test program tserver.c. (check-in: 8cbe8f2b user: dan tags: server-process-edition)

13:59
Add support for tab-completion (using the ext/misc/completion.c virtual table) to the command-line shell. (check-in: 95cd1d9f user: drh tags: trunk)
13:34
Change the src/shell.c file so that it is generated from a new script at tool/mkshellc.tcl and the template file src/shell.c.in, and automatically includes the extensions it needs out of ext/misc. (check-in: 17e0bb12 user: drh tags: trunk)
02:53
Fix a backup2 test case so that it works on FreeBSD. (check-in: 724819b4 user: drh tags: trunk)
02:05
Add the "phase" output column on the COMPLETION table-valued function, for debugging. Improved comments on the implementation. (check-in: 0e213555 user: drh tags: trunk)
01:38
The COMPLETION virtual table now looks at the names of databases, tables, and columns in addition to SQL keywords. (check-in: 1cc97711 user: drh tags: trunk)
00:09
Incomplete implementation of the COMPLETION table-valued function. So far it only works for SQL keywords. (check-in: caefbc72 user: drh tags: trunk)
2017-07-10
21:32
Fix harmless compiler warnings in lsmtest. (check-in: bd8a1fb9 user: mistachkin tags: trunk)

Cleanup header usage in lsmtest for files that require _O_BINARY. (check-in: f3a6a64e user: mistachkin tags: trunk)
18:52
Updates to the repository README.md file. (check-in: 7bfd3ab7 user: drh tags: trunk)
18:33
In LSM, avoid calling the VFS xTestLock method to test for a lock that conflicts with one held by the same process. The results of such a call are considered undefined (since they are different under win32 and posix). (check-in: a82a9bea user: dan tags: trunk)
18:04
Add the "--newlines" option to the ".dump" command in the shell to disable the newline escaping mechanism. (check-in: bde431b1 user: drh tags: trunk)
17:00
When multiple constraints need to be evaluated for a row, do any constraints that involve correlated subqueries last. Hence, the priority is index-covered constraints first, correlated subquery constraints last, and all others in the middle. This is a follow-on and improvement to the push-down optimization of check-in [d7bb79ed]. (check-in: c4cb9048 user: drh tags: trunk)
16:38
Additional debugging Noop-comment in the constraint generator when wheretrace is enabled. (Closed-Leaf check-in: 0ca7474f user: drh tags: defer-where-subqueries)
15:26
Small performance optimization in sqlite3WhereExprUsage(). (check-in: 38edc677 user: drh tags: defer-where-subqueries)
15:17
Fix another problem on this branch. (check-in: a4fc9811 user: dan tags: defer-where-subqueries)
14:39
Fix a problem causing non-covered WHERE terms to be evaluated before covered WHERE terms. (check-in: 7d3cb39f user: dan tags: defer-where-subqueries)
14:33
When testing non-indexed WHERE constraints, test those that involve correlated sub-queries last of all. This increases the chances of not having to run the sub-query at all. (check-in: 1f9c1f35 user: dan tags: defer-where-subqueries)
13:24
For sqlite3TreeView() debugging output, show the Expr.flags field on scalar subqueries. (check-in: dc857a96 user: drh tags: trunk)
12:07
Update error message text for standard error codes to better describe the latest usage of those error codes. Modify sqlite3_open_v2() so that it does return a valid sqlite3 object in the event of SQLITE_MISUSE due to bad open flags, so that sqlite3_errmsg() does not report "out of memory" in that case. (check-in: f27b6370 user: drh tags: trunk)
11:17
Remove the error message text from disused error codes such as SQLITE_EMPTY and SQLITE_FORMAT. (check-in: 871752f2 user: drh tags: trunk)
2017-07-09
18:55
Always make "column%d" column-names 1-based, never 0-based. (check-in: 70096c50 user: drh tags: trunk)
00:30
Make sure the columns of a VALUES() clause are named "column%d" even if the VALUES() clause is a subquery in the FROM clause of an outer query. (check-in: acf3b9cc user: drh tags: trunk)
2017-07-08
22:30
Add the --icc, --gcc7, and --orm options to the speed-check.sh test script. (check-in: 70dae08a user: drh tags: trunk)

Support read-only MVCC transactions in server-mode. Started using "BEGIN READONLY". (check-in: 5a043aa8 user: dan tags: server-process-edition)
18:27
Disable compiler intrinsics when using the Intel C Compiler. (Leaf check-in: dbb59f61 user: drh tags: icc-fix)
01:01
Fix the covering index OR optimization (check-in [fcbd6abd]) so that it works with SQLITE_MAX_ATTACHED>30. Broken by a bad cherry-pick merge. (check-in: d227de8a user: drh tags: branch-3.8.9)
2017-07-07
22:58
Merge in all the latest trunk enhancements. (check-in: 7f48f6ab user: drh tags: apple-osx)
22:47
Basic test cases for PRAGMA secure_delete=FAST. (check-in: 0c246017 user: drh tags: trunk)
22:39
Fix test cases in wal2.test due to the fact that Darwin checks to see if the SHM file is writable before attempting to open in read/write. (check-in: 6b618b18 user: drh tags: apple-osx)
21:20
Fix comment in the Win32 VFS for lsm1. (check-in: 12a421bc user: mistachkin tags: trunk)
21:15
For lsmtest, use a more portable means of setting open() files to binary. (check-in: aea6e0ff user: mistachkin tags: trunk)
20:35
Adjust copy_file() lsmtest function so it works properly for locked database files on Win32. (check-in: 54a38555 user: mistachkin tags: trunk)
20:33
Avoid even trying to open a SHM file read/write in WAL mode if we know that the file is read-only. This avoids scare security log messages. (check-in: d9d92781 user: drh tags: apple-osx)
20:06
Add the "PRAGMA secure_delete=FAST" option, which overwrites most deleted content without increasing the amount of I/O. Deleted content might persist on the free page list, however. And extra CPU cycles are used for zeroing, of course. (check-in: 38978ce6 user: drh tags: trunk)
19:43
Change the error message text for SQLITE_ERROR to omit the part about "missing database" as that meaning is now obsolete (since approx SQLite 2.0). (check-in: 732f90d6 user: drh tags: trunk)
19:22
Fix typos in Win32 VFS for lsm1. (check-in: 0961ec87 user: mistachkin tags: trunk)

In the command-line shell, when running ".schema" give a sensible error when the database file is locked. (check-in: cc329eb8 user: drh tags: trunk)
17:57
Fix the usleep() macro in the Win32 test code for lsm1. (check-in: 63599fa5 user: mistachkin tags: trunk)
17:43
Add new PRAGMAs: "function_list", "module_list", and "pragma_list". All are enclosed within #ifdef SQLITE_INTROSPECTION_PRAGMAS. The compile-time option is not on ctime.c yet, since these are still experimental and one can always test "PRAGMA pragma_list" and see whether or not it returns an empty set. (check-in: e0b6ae92 user: drh tags: trunk)
17:33
Add the "Pragma_list" pragma. Put all three pragmas created on this branch inside of #ifdef SQLITE_INTROSPECTION_PRAGMAS. (Closed-Leaf check-in: 2f3c3781 user: drh tags: list-pragmas)

16:12
Have this branch maintain an in-memory hash-table of old pages for read-only MVCC clients. There is no way to access it yet. (check-in: a3a9a2e1 user: dan tags: server-process-edition)
16:09
In lsmtest, use an empty string instead of ":memory:" when requesting a temporary database from SQLite. This prevents other test code from trying to unlink() ":memory:", which fails on win32. (check-in: 281ad505 user: dan tags: trunk)
16:07
Remove a block from the Win32 VFS for lsm1 that is now superfluous. (check-in: db4a4140 user: mistachkin tags: trunk)

Memory reallocation fix for the Win32 VFS for lsm1. (check-in: 5a3140e4 user: mistachkin tags: trunk)
16:00
Enhance the sqlite3VdbeMultiLoad() interface to automatically generate the OP_ResultRow opcode on PRAGMA implementations, for a small reduction in the library footprint. (check-in: c46f0f07 user: drh tags: trunk)
15:43
Add new pragmas: "function_list" and "module_list" (check-in: e5f01d7f user: drh tags: list-pragmas)
14:54
Fix an obsolete comment on the sqlite3_namelist() function implementation. (Closed-Leaf check-in: f4229857 user: drh tags: experimental-namelist)
14:26
Merge recent enhancements from trunk. (check-in: 73d0fc02 user: drh tags: bind-pointer)
13:59
Exploit the fact that Expr.pRight and Expr.x are never used at the same time for a small performance gain. (check-in: aacbb9a4 user: drh tags: trunk)
12:58
More efficient and compact implementation of walkExpr(). (check-in: 115d4b83 user: drh tags: trunk)
12:43
More aggressive use of EP_Leaf on expression nodes, to help prune searches. (check-in: c1a1d68c user: drh tags: trunk)
11:49
Very slightly smaller and faster sqlite3WalkSelect(). (check-in: 9bc65635 user: drh tags: trunk)
2017-07-06
22:43
Small adjustment to main.mk that facilitates giving non-standard compile-time options to the shell. (check-in: 7c7d53a9 user: drh tags: trunk)
22:40
Always load the schema before starting tab-completion. (check-in: 907fd3aa user: drh tags: experimental-namelist)
20:08
Tab-completion now also works using readline/editline. (check-in: c906739f user: drh tags: experimental-namelist)
19:26
Use the sqlite3_namelist() interface to implement simple tab-completion using linenoise. (check-in: 5cc7b0e2 user: drh tags: experimental-namelist)
18:52
Change the sqlite3_namelist() interface to return a pointer to an array of pointers to strings, and to avoid duplicates. (check-in: 70291110 user: drh tags: experimental-namelist)
18:25
The sqlite3_namelist() routine now works for all name types. (check-in: e41d6217 user: drh tags: experimental-namelist)
17:36
Initial implementation of a highly experimental interface for listing all keywords and symbolic names for an SQLite database connection. (check-in: 04ef6783 user: drh tags: experimental-namelist)
16:33
Change the (machine-generated) keywordhash.h file to increase the scope of the tables used for keyword matching, so that the tables are accessible to functions other then keywordCode(). (check-in: c5ed5ebd user: drh tags: trunk)
13:51
More compact implementation of the typeof() SQL function. (check-in: efb4aab0 user: drh tags: trunk)
13:23
Avoid unnecessary upper-to-lower case conversion for function names when registering the built-in functions. (check-in: 06269257 user: drh tags: trunk)
03:06
Small size reduction in findCollSeqEntry(). (check-in: 55ecd303 user: drh tags: trunk)

18:48
Have fts3 virtual table cursors free internal resources when they reach EOF, instead of waiting until the xClose method is called. (check-in: b6b14ab6 user: dan tags: trunk)
16:20
Make use of covering indexes in the OR optimization. (check-in: fcbd6abd user: drh tags: branch-3.8.9)

Enhance the RTree module to detect node truncation early and report an error. (check-in: 66de6f4a user: drh tags: trunk)
2017-06-30
23:46
Update the carray() and remember() extension functions so that they user the new sqlite3_value_pointer() interface. (check-in: a99fa94d user: drh tags: bind-pointer)
23:09
Add APIs for binding pointers that can be used by app-defined functions. (check-in: d9f4a831 user: drh tags: bind-pointer)

Add some assert() statements in the Win32 interface for lsm1. (check-in: d076d58f user: mistachkin tags: trunk)
18:12
Fix some minor typos in lsm1. (check-in: 0ef777d7 user: mistachkin tags: trunk)
11:44
Avoid constantly freeing and reallocing small internal buffers associated with LSM cursors. Instead, allow them to persist for the lifetime of the cursor if they are LSM_SEGMENTPTR_FREE_THRESHOLD (default 1024) bytes or smaller. This change is based on research by Martijn Blaauw. (check-in: bacfe8cb user: dan tags: trunk)
2017-06-29
21:33
In the command-line shell, add the -quote option to start up in quote mode. Enhance the ".mode" command so that it reports the current output mode if given no arguments. (check-in: 5e3f9ea5 user: drh tags: trunk)
21:11
Remove the ".explain" command from the ".help" output of the command-line shell, though keep the implementation around for backwards compatibility. (check-in: 7782c04e user: drh tags: trunk)
20:31
Some simple tests for the STMT virtual table. (check-in: a26e17ee user: drh tags: trunk)

When doing a DISTINCT query using an index, try to use the index to skip ahead to the next distinct element, rather than doing a full scan of the index. (This is the "skip-ahead-distinct" optimization.) (check-in: f489b5bb user: drh tags: trunk)
17:18
An initial attempt to optimize VIEWs that occur as the right operand of a LEFT JOIN.

Forward port the skip-ahead-distinct branch which was abandoned for some reason that I do not recall. This port should have been achived by a merge of trunk into the previous head of skip-ahead-distinct, but that did not work. So I had to manually "rebase" the changes.

18:31
Merge all recent changes from trunk. (check-in: 3d04b2cd user: drh tags: apple-osx)
18:24
In the output of the ".dump" command in the CLI, quote newline and carriage-return characters using the char() function, so that they do not get eaten by end-of-line processing logic in the OS or in other command-line utilities and/or libraries. (check-in: 68f6dc7a user: drh tags: trunk)

13:45
In the OSSFuzz test module, invoke the progress handler much more frequently so that timeouts are detected punctually even if the test script is running opcodes that individually take a long time (for example, an OP_Function opcode that invokes "randomblob(1.5e6)"). (check-in: f3b6959c user: drh tags: trunk)
2017-03-12

01:56
The output of the ".dump" command in the CLI quotes newline and carriage-return characters using "char(10)" and "char(13)". (Closed-Leaf check-in: 8b2954dd user: drh tags: string-quoting-dump)

14:36
Enhance the ".stats" dot-command in the CLI to use sqlite3_status64() instead of sqlite3_status(). (check-in: 118f5c05 user: drh tags: trunk)
01:05
Improvements to ".selftest --init". Tests are number in increments of 10 starting with 100. The tests are generated inside a SAVEPOINT. Errors are reported during test generation.

2017-03-09
22:00
Remove the test/dbselftest.c program. In its place, add the ".selftest" command to the CLI. The new CLI version is .selftest is slightly different in that it uses SHA3 hashing instead of SHA1, so the new is subtly incompatible with the old. (check-in: f4fcd46f user: drh tags: trunk)
18:13
Fix the ".dump" command to correctly extract tail data from corrupt WITHOUT ROWID tables. (check-in: 6c627e50 user: drh tags: trunk)
16:32
Add the --recovery-mode option to the CLI ".dump" command. This involves enhancing the "PRAGMA reverse_unordered_selects" command to accept a "TOGGLE" option. Recovery mode used to be always on. Now it is opt-in. Not sure this is the correct approach. Also not sure if TOGGLE is a good feature to have on boolean PRAGMA statements. (Closed-Leaf check-in: 5dc82a15 user: drh tags: dump-recovery)
13:50
Begin moving separate boolean variables in the ShellState object of the CLI into the shellFlgs bitmask. (check-in: 50eec5d9 user: drh tags: trunk)

17:56
In the ".sha3sum" command, if there is a LIKE pattern, show the hashes for each table separately. Without a LIKE pattern, show a single hash over the entire database. (check-in: 30f87883 user: drh tags: trunk)
16:10
Add the ".sha3sum" command to the CLI - used to compute a cryptographic hash of the content of a database file or of individual tables with in that file. (check-in: fc663799 user: drh tags: trunk)

2017-01-28
20:46
In the amalgamation, allocate the parser engine object from stack rather than from heap, for improved performance. This only happens in the amalgamation, since otherwise the sqlite3RunParser() routine does not know the object size. (check-in: 4fe879d4 user: drh tags: trunk)

In the command-line shell, enhance the ".mode" command so that it restores the default column and row separators for modes "line", "list", "column", and "tcl". (check-in: 58f02e6e user: drh tags: trunk)
01:25
Another micro-optimization in accessPayload(). Slightly smaller and faster. (check-in: c012619b user: drh tags: trunk)
01:13
Performance optimization in accessPayload(). (check-in: ebb1fd98 user: drh tags: trunk)
00:31
Simplify the accessPayload() routine so that it always populates the overflow page cache. In the one case where populating the page cache can lead to problems, simply invalidate the cache as soon as accessPayload() returns. This simplification reduces code size and helps accessPayload() to run a little faster. This backs out the eOp==2 mode of accessPayload() added by check-in [da59198505]. (check-in: 68e7a8c6 user: drh tags: trunk)

00:58
Modify the ICU extension to use a static initializer, as VC++ complains about a dynamic initialization. Maybe the dynamic structure initialization is a GCC extension. This fixes a problem identified on the SQLite mailing list by Ziemowit Laski. (check-in: 50e60cb4 user: drh tags: trunk)
2017-01-25
20:55
Trim NULL values off the end of records when the SQLITE_ENABLE_NULL_TRIM compile-time option is used. Increase the size of the P5 operand to 16 bits. Fix a problem with short records in the sessions extension. (check-in: 4801bd59 user: drh tags: trunk)

A better implementation of the moveto-neighbor optimization that checks for nearby rows on adjacent pages. (Closed-Leaf check-in: 2c4ecb85 user: drh tags: btree-moveto-neighbor)
16:54
B-tree optimization: When seeking on a rowid table that has already been positioned, check to see if the new row happens to be the next row on the same leaf page. That is a reasonably common case, and if it is true it avoids a full binary search. (check-in: 8e5cfb20 user: drh tags: btree-moveto-neighbor)
16:27
Change sqlite3_blob_reopen() to call sqlite3VdbeExec() directly rather than going through sqlite3_step(). Performance enhancement. (check-in: 347df3c1 user: drh tags: trunk)

Add extra (somewhat inefficient) trace callbacks for triggers if SQLITE_TRACE_TRIGGER is defined. (check-in: ffda1d1e user: dan tags: trigger-trace)
15:55
In the kvtest.c test utility, reuse the buffer into which blobs are read, rather than reallocating it for each row. This is a closer match to how other test programs work, and thus provides a better comparison. (check-in: 0d1ad13a user: drh tags: trunk)
15:30
A proof-of-concept for running sqlite3_blob_open() without using OP_Column when operating on a pure key/value table. This demo does not include any corrupt database checking. Uses about 3% fewer CPU cycles on a key/value performance test. (Leaf check-in: 4cda3b30 user: drh tags: kv-access-opt-demo)
14:11
Remove an unnecessary sqlite3_bind_int64() call from sqlite3_blob_open(). Also other minor refactoring of the sqlite3_blob implementation. (check-in: 9d197a53 user: drh tags: trunk)

2017-01-19
21:20
If compiled with SQLITE_INLINE_MEMCPY, all memcpy() calls are replaced with in-line code. With that change, cachegrind shows which memcpy() calls are taking the most time. This is a performance-measurement hack only and is not for production use. (check-in: 9ed38521 user: drh tags: trunk)
18:20
In the 'vtshim' extension, avoid accessing freed memory when handling errors from xCreate/xConnect. (check-in: ffd559af user: mistachkin tags: trunk)

2017-01-17
10:41
Fix a problem that could cause a spurious SQLITE_NOMEM error when attempting to resume an RBU operation if the previous client failed right after completing the incremental checkpoint. Also a "cannot vacuum wal db" error that could occur when resuming an RBU vacuum if an error (OOM or IO error) occurs during the incremental checkpoint. (check-in: 681d96eb user: dan tags: trunk)
00:10
Disable intrinsic functions for Windows using Clang, due to reports of linkage errors. This causes a 0.6% performance reduction. We will want to revisit this change in the future. (check-in: 7fd560c6 user: drh tags: trunk)

In the pager, avoid checking for the illegal page number 0 except when creating a new page. (Closed-Leaf check-in: dee20ba9 user: drh tags: pager-get-method)
16:57
Fix a problem causing SQLite to return false "foreign key violation" errors when there is a partial (i.e. WHERE constrained) UNIQUE index on the parent key columns. This bug did not cause SQLite to allow illegal data to be inserted into the database, only to reject legal operations. (check-in: 850877d1 user: dan tags: trunk)
15:53
Further refinements to the virtual method implementation of sqlite3PagerGet(). (check-in: 67df4446 user: drh tags: pager-get-method)
14:32
Make the sqlite3PagerGet() interface into a virtual method, with different implementations based on the current state of the pager. This gives a small performance increase by avoiding unnecessary branches inside the various methods. (check-in: df5bb90d user: drh tags: pager-get-method)

Avoid an unnecessary memset() in the sqlite3BtreeInsert() routine. (check-in: 35ecd4eb user: drh tags: trunk)
12:58
Reorder the fields in the VdbeCursor object so that those that need to be bulk zeroed on allocation are grouped at the beginning, and the memset() only runs over those fields that really need it. (check-in: 8165f88b user: drh tags: trunk)
04:06
Avoid signed integer overflow when dealing with a LIMIT and OFFSET whose sum exceeds the maximum integer value. (check-in: c9bdf7ad user: drh tags: trunk)

When flattening a query of the form "SELECT * FROM (SELECT * FROM tbl WHERE x=?) WHERE y=?", ensure that the final WHERE clause is "x=? AND y=?" instead of "y=? AND x=?". Although it is still not guaranteed, this makes the order in which WHERE clause terms are processed comport more closely to users expectations. (check-in: cf7f9e6d user: dan tags: trunk)

18:53
Remove the internal sqlite3CodeOnce() interface, replacing it with a direct call to sqlite3VdbeAddOp0(v,OP_Once). Slightly smaller and faster. (check-in: c3774c6a user: drh tags: trunk)

09:28
Have releasetest.tcl delete all test files except for "testfixture", "testfixture.exe", "sqlite3", "sqlite3.exe", "test.log" and "test-out.txt" after each test run is finished. Passing the "--keep" option restores the old behaviour. (check-in: e0e042dc user: dan tags: trunk)

The previous commit could miss an SQLITE_NOMEM error. This commit catches it. (Closed-Leaf check-in: 3a9f4750 user: dan tags: mistake)
17:18
Within a backup operation, ensure that a read-transaction is opened on the source database before its page size is read. This ensures the page-size used to write to the backup database is the same as its actual page-size, which is important for ZipVFS databases. (check-in: 7908fc60 user: dan tags: trunk)
2016-09-01
14:03
Have "sqldiff --rbu" ignore rows with NULL values in primary key fields. RBU can't handle such rows and the documentation already says sqldiff ignores them. Because the code now uses "=" instead of "IS" to filter on primary key columns, diffs on virtual tables are faster now too. (check-in: f4ba894a user: dan tags: trunk)
09:35
If SQLITE_ENABLE_ZIPVFS is defined, journal_mode=off is configured and a savepoint or statement rollback is attempted, move the pager into the error state to prevent the transaction from being committed. This makes it safe to use journal_mode=off with zipvfs under some conditions. (check-in: 38d31e18 user: dan tags: trunk)

Fix the extra comments (added with -DSQLITE_ENABLE_EXPLAIN_COMMENTS) so that the sense of <, <=, >, and >= tests is correct and so that the SQLITE_STOREP2 version is shown correctly.

Btree interface refactoring: (1) The sqlite3BtreeKeySize() interface is renamed to sqlite3BtreeIntegerKey() and modified to work only for table btrees with a rowid. (2) The sqlite3BtreeDataSize() interface is renamed to sqlite3BtreePayloadSize() and modified to work with any btree.

Fix an obscure problem with transactions written in "PRAGMA synchronous=full" mode on systems that do not support POWERSAFE_OVERWRITE causing an xSync() call to be omitted if the last frame written by a transaction is aligned to a sector boundary.

For queries with both ORDER BY and LIMIT, if the rows of the inner loop are emitted in ORDER BY order and the LIMIT has been reached, then optimize by exiting the inner loop and continuing with the next cycle of the first outer loop. (check-in: 559733b0 user: drh tags: trunk)
13:44
Set the NULLEQ flag on the sequence counter comparison in the ORDER BY LIMIT optimization, to avoid coverage complaints about not testing the NULL case. (Closed-Leaf check-in: ed1b30dc user: drh tags: orderby-limit)

Corrections to comments on the whereScanInit() interface. (check-in: ab7ab415 user: drh tags: trunk)
16:49
For DELETE operations, make sure that seeks on the main table are not deferred, since if they are and none of the indexes reference columns of the table, the seek might never occur until the OP_Delete opcode, which is too late. Fix for ticket [16c9801ceba49]. (check-in: 93a2bace user: drh tags: trunk)
16:30
Fix an error in main.mk causing testfixture to use individual fts5 source code files instead of fts5.c. (check-in: 933a1c81 user: dan tags: trunk)

16:44
If a call to sqlite3rbu_close() on an rbu handle opened by sqlite3rbu_vacuum() returns other than SQLITE_OK, delete the contents of the rbu_state table.

Merge the tokenizer buffer overrun bug-fix from trunk. (check-in: 82e7e31b user: drh tags: apple-osx)
14:49
Avoid a potential buffer overrun if an SQL statement being parsed ends with an illegal "!" token. (This problem was detected by fuzzcheck running under valgrind. The problem was introduced by check-in [9570b6b43df3], two days ago and has not appeared in a release.) (check-in: 2a8d97e7 user: drh tags: trunk)

When VDBE opcodes fail, they cause an immediate exit from the loop, rather than depending on the rc==SQLITE_OK test at the top of the loop. This is faster and smaller. (check-in: 24c7151c user: drh tags: trunk)
20:06
Schemalint changes: Avoid creating candidate indexes if a compatible index exists. Do not quote identifiers that do not require it. (check-in: cf0f7eeb user: dan tags: schemalint)

17:27
Enhance mptester so that it takes great care to delete its test database prior to start-up, including checking the return code from unlink() and retrying after a delay if unlink() fails. Hopefully this will clear intermittant startup problems on Windows. (check-in: 6ea84ec1 user: drh tags: trunk)
05:19
Naming updates for Universal Windows Platform. (check-in: 717c1fc4 user: mistachkin tags: trunk)

20:04
Improved auto-detection of EXPLAIN output in the shell. (Closed-Leaf check-in: 6c6d7a6e user: drh tags: auto-explain)

Faster keywordCode() implementation by taking advantage of the fact that the input is always pure ASCII alphabetic and underscore and that the keyword table is always upper-case. (check-in: ff406b97 user: drh tags: tokenizer-char-class)
02:30
Demonstrate a much faster sqlite3GetToken() routine by using a lookup table to map initial token characters into a character class. This check-in does not work for EBCDIC. More optimization needed. (check-in: 9115baa1 user: drh tags: tokenizer-char-class)

The top of an index equality loop normally starts with OP_SeekGE and OP_IdxGT. This check-in adds a flag to OP_SeekGE such that it fails immediately if the key is not equal, then jumps over the OP_IdxGT, saving a call to the key comparison functions.

13:54
Virtual table modules with a null xCreate method act as eponymous-only modules - they cannot be used in a CREATE VIRTUAL TABLE statement.

15:29
Update the [showdb] program so that the database file is read directly (bypassing the SQLite VFS) only if the --raw option is specified. Otherwise, it is read using the default VFS. Also, the URI syntax may be used on the command line to specify the name of the database file to examine, so an alternative VFS may be requested using a URI parameter. (check-in: e3c6d4b6 user: dan tags: trunk)
15:23
Update the [showdb] program so that the database file is read directly (bypassing the SQLite VFS) only if the --raw option is specified. Otherwise, it is read using the default VFS.

2015-08-03
17:03
Add the "--uri" option to utility program "showdb". This option causes showdb to use sqlite with the SQLITE_OPEN_URI option to open the database file, instead of opening it directly using the OS open() function. (check-in: 90e34d51 user: dan tags: showdb-uri-option)
13:44
Allow a VIEW to reference undefined tables and functions when initially created. The error report is deferred until the VIEW is used. This allows views to be created before subviews and tables that the view references. (check-in: 70b57daf user: drh tags: trunk)

Using "SELECT ALL" instead of just "SELECT" on a query that uses a single unflattenable subquery or view in its FROM clause will force the subquery to be manifested into a temporary table rather than run incrementally using a co-routine.

Make sure that the KeyInfo.nXField value of ephermeral tables used for ORDER BY and GROUP BY is set correctly, so that the correct comparison function can be choosen by sqlite3VdbeFindCompare(). (check-in: c16bae5e user: drh tags: tkt-f97c4637)
20:57
Fix the assert() of the previous check-in so that it works even when compiled without SQLITE_DEBUG. (check-in: 38868f84 user: drh tags: tkt-f97c4637)

Fix compilation on Cygwin when SQLITE_MAX_WORKER_THREADS is greater than zero. (check-in: 2037442c user: mistachkin tags: trunk)
19:48
An alternative way of implementing the assert() that verifies the relative values of KeyInfo.nField+KeyInfo.nXField and the number of columns in a record. This version of the assert() only fires when the high-speed comparison routines are used - which is to say it only fires when the constraint actually matters. (check-in: bf744b49 user: drh tags: tkt-f97c4637)
19:21
An alternative way of fixing the key comparison bug of ticket [f97c4637102a3ae72b]. (Closed-Leaf check-in: e41376cf user: drh tags: alt1-tkt-f97c4637)

17:28
Add an assert() to verify that the nField+nXField values of a KeyInfo object are never less then the number of columns in a row for a non-corrupt database. This assert() currently fails, which is the root of the problem with ticket [f97c4637102a3ae72b]. (check-in: 083f523d user: drh tags: tkt-f97c4637)

Simplify some code in rtree, to avoid confusing the optimizer in GCC on some macs: gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00). Prior to these changes, compiling with -O3 would cause incorrect code to be generated. The change to the nodeGetCell() routine is key. The other changes are merely cosmetic details discovered while bug hunting. (check-in: 882181ff user: drh tags: trunk)

Make use of the fdatasync() interface if the HAVE_FDATASYNC macro is true. (check-in: 694228e4 user: drh tags: trunk)
16:49
Improvements to compile-time-option hygiene. Use "#if OPTION" instead of "#ifdef OPTION" in cases where that makes sense, so that -DOPTION=0 will work. Add the "Have-Not" configuration in releasetest.tcl which disables all of the "HAVE_component" compile-time options. (check-in: 9e92a5ed user: drh tags: trunk)

20:13
Enhance "INSERT INTO ... VALUES" so that the number of rows in the VALUES clause is not limited by SQLITE_LIMIT_COMPOUND_SELECT, and so that the stack depth is constant regardless of the number of rows in VALUES. (check-in: e1c4a359 user: drh tags: trunk)
20:04
Avoid O(N*N) behavior with very long lists of VALUES. (Closed-Leaf check-in: ee30fb35 user: drh tags: many-VALUEs)

Handle compound-select statements originating from VALUES clauses as a special case that does not use recursion. (check-in: 9ce9e43a user: drh tags: many-VALUEs)
16:27
Towards getting INSERT statements to except many VALUE terms (more than the limit imposed by SQLITE_LIMIT_COMPOUND_SELECT). This check-in segfaults on a stack overflow. And it is slow. (check-in: c9d65f73 user: drh tags: many-VALUEs)

19:11
Enhance the "lemon" executable so that it ignores -f, -W, -O, and -I command-line options. This permits most of the same options that are passed to the compiler to also be harmlessly passed to lemon, and thus simplifies makefiles. (check-in: da408d12 user: drh tags: trunk)

19:26
Update the threadtest3 test program so that its output summary is compatible with releasetest.tcl. In threadtest3, do not record errors that contain the string "no such table" as being fatal errors, since they happen sometimes in a race condition in stress1. (check-in: 98cb56e2 user: drh tags: trunk)
18:07
Fix problems with the "inmemory_journal" permutation. (check-in: 79693f04 user: dan tags: trunk)

Fix a bug in the threadtest4.c program. Remove the keyinfo cache as it provides minimal performance improvements, and then only at SQL preparation time, not at runtime, and it has problems with data races in shared-cache mode.

19:07
Make the sqlite3_table_column_metadata() interface available by default and without requiring the SQLITE_ENABLE_COLUMN_METADATA compile-time option. Other sqlite3_column_* interfaces that have a run-time penalty even if they are unused still require the SQLITE_ENABLE_COLUMN_METADATA option at compile-time. (check-in: 4f7549ff user: drh tags: trunk)

13:42
Increase the resolution of the second parameter to the likelihood() SQL function (the probability value) so that it can handle probabilities as small as 0.00000001. Formerly, it ran out of precision at 0.001. (check-in: 0f08924f user: drh tags: trunk)

Disable the use of strchrnul() unless specifically enabled by compile-time options. (check-in: e580470d user: drh tags: trunk)
19:57
Change the 0x800 bit of SQLITE_TESTCTRL_OPTIMIZATIONS so that it disables the loading of STAT3 and STAT4 content, not just the using of that content. Change the internal name of that bit to SQLITE_Stat34. (check-in: ca3b00c4 user: drh tags: trunk)

Add WHERETRACE debugging output to the whereLoopAdjustCost() routine. (check-in: ec1e942f user: drh tags: trunk)
01:05
If a skip-scan is a proper subset of some other scan, then adjust the cost of the skip-scan upward so that it is more costly than the other scan. Such a cost imbalance can arise under STAT4 because of difficulties in getting an accurate estimate for skip-scans. (check-in: f4b22a26 user: drh tags: trunk)

Optimize a database corruption test inside of the OP_Column opcode. (check-in: 005e5b38 user: drh tags: trunk)
20:12
Use the padding word in the Mem object as temporary storage for serial_type value in OP_Record, and thus avoid a redundant computation of the serial_type for each column. (check-in: 4b3b65ee user: drh tags: trunk)

17:42
Three small optimizations to vdbeaux.c. (check-in: 04892f8b user: drh tags: trunk)
16:02
Reduce the CPU load imposed by sqlit3VdbeCursorMoveto() by factoring out some of its functions and by avoiding unnecessary calls. (check-in: c2799aec user: drh tags: trunk)
13:00
Remove the OPFLAG_CLEARCACHE flag from OP_Column. In its place, change the P3 parameter of OP_SorterData to be the index of the pseudo-table cursor whose record header cache is to be cleared. This gives a small size reduction and performance increase. (check-in: 20062f49 user: drh tags: trunk)
12:30
Use OP_SorterColumns in aggregate queries. Remove OPFLAG_CLEARCACHE. (Closed-Leaf check-in: 134e65c0 user: drh tags: OP_SorterColumns)
01:23
Add the OP_SorterColumns opcode - an experiment in using a special case opcode to decode the Sorter output rather than the generic OP_Column. This might be faster. And with further work, it could eventually eliminate the need for OP_OpenPseudo. (check-in: b9c695e8 user: drh tags: OP_SorterColumns)
2014-10-12
22:37
Remove the VdbeCursor.lastRowid cache of the current rowid, since maintaining the correct cache value uses more CPU cycles than just recomputing the rowid on the occasions when it is actually needed. Replace it with the VdbeCursor.aOffset field which used to be computed from VdbeCursor.aType when needed. Saves 100 bytes of code space and runs 0.2% faster.

Attempt to further reduce memcpy() in balance_nonroot(). (check-in: fec849dc user: dan tags: defrag-opt)
17:22
Simplification to the insertCell() routine in btree.c, resulting in a performance boost and a very small size decrease. It turns out that the extra work involved in sometimes avoiding an memcpy() of the first four bytes of a record takes more time than just unconditionally copying those four bytes. (check-in: 66de1558 user: drh tags: trunk)
10:52
Require the SQLITE_ENABLE_RTREE compile-time option in speedtest1.c in order to enable the R-Tree tests. (check-in: 5d29a033 user: drh tags: trunk)

17:44
Provide the new "-config CONFIG" option to the test/releasetest.tcl script, which allows one to run a single test configuration selected by name. (check-in: d479e32b user: drh tags: trunk)
17:20
Add the estimated number of output rows to the EXPLAIN QUERY PLAN output if compiled with SQLITE_EXPLAIN_ESTIMATED_ROWS. This feature is off by default for the time being. (check-in: daa8314f user: drh tags: trunk)
15:47
Simplify the code used to generate the text for EXPLAIN QUERY PLAN. (check-in: beea1efc user: drh tags: trunk)

15:08
Allow FTS tokenizers to choose whether or not to consider the "*" character part of tokens or not. This restores the pre-[e21bf7a2ad] behaviour. Also fix a problem causing FTS to interpret tokens beginning with "*" characters as EOF. (check-in: 49dfee7c user: dan tags: trunk)
14:10
Add a test case for the memory leak fixed by the previous check-in. (check-in: bae36d54 user: drh tags: trunk)

2014-10-07
23:02
Make sure the sqlite3VdbeMemClearAndResize() routine is never called with a zero size parameter, since a size of zero could lead to either a memory leak or an assertion fault. (check-in: f672a380 user: drh tags: trunk)

00:07
Avoid leaking Index.aiRowEst memory if an OOM causes a rollback which deletes the index before the aiRowEst deletion code in sqlite3AnalysisLoad() routine has a chance to run. Since the aiRowEst now might be deleted from freeIndex() which does not always have a db pointer, make sure the aiRowEst memory is not held in lookaside. (check-in: efd87ba1 user: drh tags: stat4-avgeq)
2014-10-03

2014-09-27
20:45
Change the names of the stream interface APIs to be of the form "_strm" instead of "_str". In other words, added an "m" to the end, to try to make it clear that we are talking about a "stream" and not a "string. (check-in: 1f44bfdc user: drh tags: sessions)

Fix a problem with concatenating patchsets containing DELETE and INSERT operations on the same row. (check-in: 4d8537ea user: dan tags: sessions)
02:41
Fix the "PRAGMA integrity_check" command so that it avoids formatting error message context messages until it actually needs to generate an error message. This avoids much formatting, and hence greatly improves the performance of "PRAGMA integrity_check" in the common case when there are no errors. It also makes the code a little smaller. (check-in: 83913515 user: drh tags: trunk)
01:10

Experiment using linear interpolation, instead of a strict binary search, when looking for integer-keyed rows on a single b-tree page. The experiment was not successful. The number of key comparisons is reduced by about 15%, but the added complexity of the search logic causes an overall reduction in performance. The patch is saved for historical reference only. (Closed-Leaf check-in: c705cf85 user: drh tags: linear-interpolation)

Improvements to the way the query planner handles sorting costs, so that very large sorting costs do not overwhelm the loop costs. (check-in: bdaa6947 user: drh tags: trunk)
17:25
Fix a buffer overrun in the previous commit. (Closed-Leaf check-in: 43c59c85 user: dan tags: query-planner-fix)
16:52
Because SQLite internally calculates query plan costs using a logarithmic scale, very large estimated sorting costs can cause all other estimated costs to be rounded down to zero. In these cases break ties between plans with the same total cost by comparing the costs with sorting excluded. This is an alternative fix for the problem addressed by [2af630c572]. (check-in: 299b9570 user: dan tags: query-planner-fix)
15:38
The SQLITE_IOERR_BLOCKED extended error code is not longer used, so remove assert() statements and documentation for that error code. Also make other documentation improvements. (check-in: 36b7c5ce user: drh tags: trunk)

Add "segment promotion" to fts5. This prevents the FTS index from growing indefinitely as data is added and deleted. (check-in: ba359d78 user: dan tags: fts5)
16:50
Oops! This check-in was on trunk. But it contains a debugging printf(). Original comment: When the estimated cost to do a sort overwhelms the estimated cost to do individual table lookups, make sure that the table lookup costs are still taken into consideration when selecting the lookup algorithm.

00:29
A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code. The error message is not quite as good, but as this error has apparently not previously occurred in over 8 years of heavy use, that is not seen as a serious problem. (check-in: 0ad1ed8e user: drh tags: trunk)
2014-08-05
21:31
Ensure that aggregate functions are not used when evaluating a default value for a table column. Candidate fix for ticket [3a88d85f36704eebe134f7]. (check-in: 29ba8128 user: drh tags: trunk)

Use doclist indexes for AND queries as well as phrases. (check-in: 5d38e6ed user: dan tags: fts5)
19:16
Add the ability to evaluate IN operators as a sequence of comparisons as an alternative to the long-standing algorithm of building a lookup table. Use the new implementation in circumstances where it is likely to be faster, such as when the RHS of the IN changes between successive evaluations. (check-in: 95286821 user: drh tags: trunk)

Refinements to the enhanced IN-operator logic. (check-in: 92ba2821 user: drh tags: IN-operator-improvements)
15:12
Changed my mind: This opcode name changes mere creates unnecessary diff marks between older and newer versions without significantly improving readability. Was: Rename the IsNull opcode to IfNull and rename the NotNull opcode to IfNotNull. (Closed-Leaf check-in: 2f724cba user: drh tags: deadend)
2014-08-02
21:03
Enhancements to the code generator for the IN operator that result in much faster queries in some cases, for example when the RHS of the IN operator changes for each row of a large table scan. (check-in: 436e8842 user: drh tags: IN-operator-improvements)

Have the fts5 integrity-check verify that doclist indexes match the contents of the leaf pages that they index. (check-in: 37a7d303 user: dan tags: fts5)
18:00
Remove an unnecessary OP_Null in the IN-operator logic. Attempt to clarify comments explaining the IN-operator code, though it is not clear that the comments are correct even yet - more work to be done. (check-in: c11e55fa user: drh tags: trunk)
15:51
Clean up the IN operator code generation logic to make it easier to reason about. In the process, improve code generation to omit some unused OP_Null operations. (check-in: 7c6fbcfe user: drh tags: trunk)
15:34
The idea of coding IN operator with a short list on the RHS as an OR expression turns out to be helpful. If the list is of length 1 or 2, the OR expression is very slightly faster, but the ephemeral table approach is clearly better for all list lengths greater than 2. Better to keep the code simple. (Closed-Leaf check-in: e13175d3 user: drh tags: IN-operator-improvements)
14:46
Begin making changes to the IN operator in an attempt to make it run faster and to make the code easier to understand. (check-in: ee0fd6aa user: drh tags: IN-operator-improvements)

Enhance the PRAGMA integrity_check command to detect UNIQUE and NOT NULL constraint violations. (check-in: 9abcf269 user: drh tags: trunk)
2014-07-31

Omit a pointless OP_Null when processing a value-list RHS of an IN operator where the LHS is a rowid. (check-in: 1361450a user: drh tags: trunk)

When running ANALYZE, it is not necessary to check the right-most key column for changes since that column will always change if none of the previous columns have. (check-in: 48f40861 user: drh tags: trunk)
20:02
Add the OP_ReopenIdx opcode that works like OP_OpenRead except that it becomes a no-op if the cursor is already open on the same index.

19:14
The optimization of check-in [b67a6e33f2] does not work (it generates incorrect VDBE code) if an OR term is AND-ed with a constant expression. So back that optimization out and add a test case to make sure it does not get added back in. (check-in: eed754fe user: drh tags: trunk)

Fix a harmless compiler warning. (check-in: a4e47150 user: drh tags: trunk)
03:12
Enhance the sqlite3VdbeRecordCompare() routines so that if they encounter database corruption, they will set the UnpackedRecord.isCorrupt field and return 0. The sqlite3BtreeMovetoUnpacked() routine detects this and returns SQLITE_CORRUPT, causing the corruption to be reported back to the top-level. (check-in: 7fa85eaa user: drh tags: trunk)
2014-03-27
19:25
Instead of allocating a single large buffer at the beginning of each sort operation, start with a small buffer and extend it using realloc() as required. (check-in: 81987c8c user: dan tags: orderby-planning)
18:36
Minor cleanup of the code in the query planner that computes the costs estimates for the various plans. There are no changes to the costs at this time. But the code is slightly more readable now and that might facilitate future enhancements. (check-in: 9b4d7226 user: drh tags: trunk)
17:23
Use xFetch() to access temporary files in vdbesort.c. Use a single large allocation instead of many small allocations when accumulating records in vdbesort.c. This is an interim commit - it allocates a buffer the size of the page-cache every time data is sorted. (check-in: f4ac1bf2 user: dan tags: orderby-planning)
14:05
Enhance the logest.c utility with new operators: "dup", "inv", "log", and "nlogn". Provide help on an invalid input. (check-in: b4bd2a06 user: drh tags: trunk)

Merge trunk fixes for "x IN (?)" handling. (check-in: eca35871 user: drh tags: orderby-planning)
19:04
Remove a testcase() that is now always true due to the "x IN (?)" optimization. Add an ALWAYS() around a conditional in the parser that cannot be false. (check-in: d5a1530b user: drh tags: trunk)

Only use the direct-overflow-read optimization if all data from the overflow page in question is being read. (check-in: d8e1f75d user: dan tags: overflow-pgno-cache)
18:45
Fix the EXPLAIN indenter in the command-line shell to correctly handle NextIfOpen and PrevIfOpen opcodes. (check-in: 01944c53 user: drh tags: trunk)
17:03
The "x IN (?)" optimization in check-ins [2ff3b25f40] and [e68b427afb] is incorrect, as demonstrated by the in4-5.1 test case in this check-in. The "COLLATE binary" that was being added to the RHS of IN was overriding the implicit collating sequence of the LHS. This change defines the EP_Generic expression node property that blocks all affinity or collating sequence information in the expression subtree and adds that property to the expression taken from RHS of the IN operator. (check-in: 2ea4a9f7 user: drh tags: trunk)
15:14
Fix harmless compiler warnings. (check-in: b1435f26 user: drh tags: trunk)
14:56
Previous check-in is not quite correct. "x IN (?)" is not exactly the same as "x==?" do to collation and affinity issues. The correct converstion should be to "x==(+? COLLATE binary)". The current check-in fixes this problem and provides test cases. Ticket [e39d032577df69] (check-in: 2ff3b25f user: drh tags: trunk)
13:26
Convert expressions of the form "X IN (?)" with exactly one value on the RHS of the IN into equality tests: "X=?". Add test cases to verify that statements work correctly on this corner case. Fix for ticket [e39d032577df6942]. (check-in: e68b427a user: drh tags: trunk)
12:36

Fix a problem in the block-sort logic that can arise if the VDBE opcode array is resized while the block-sort logic is being coded. "make test" now runs to completion, though there are still 17 failures. (check-in: 62f3a220 user: drh tags: orderby-planning)
15:17
Avoid reusing temporary registers in co-routines when doing block-sorting. (check-in: 463d921b user: drh tags: orderby-planning)
14:30
Make sure the where.c query planner never reports that the number of ORDER BY terms that are satisfied by indices is negative. (check-in: b186d8d1 user: drh tags: orderby-planning)
14:10
First attempt at getting block-sort to work. This is an incremental check-in. There are many problems still to be worked out. (check-in: 59742dd4 user: drh tags: orderby-planning)
2014-03-18
20:33
Make the partial-ORDER-BY information in the query planner available to the SELECT code generator. Still doesn't make a difference in the generated code. (check-in: e258df23 user: drh tags: orderby-planning)
18:59
Adjust the query planner to keep track of the number of ORDER BY terms satisfied. Still doesn't do anything with this information. Some tests fail after this check-in, but all failures are believed to be benign. The failures will be addressed at a later stage. (check-in: 59d49b7f user: drh tags: orderby-planning)

Combine the various boolean fields of the BtCursor object into a single bit-vector. This allows setting or clearing more than one boolean at a time and makes the overflow-pgno-cache branch faster than trunk on speedtest1. (check-in: 968fec44 user: drh tags: overflow-pgno-cache)

Refactor the sqlite3VdbeRecordCompare() routine used to compare btree records. Create a couple of fast-track routines to handle the common cases of a string with BINARY collation or integer values as the left-most column. This gives a significant performance boost in common use. Oops: This build does not work on the Beaglebone where "char" defaults to unsigned. (check-in: aec5473a user: drh tags: broken-on-arm)

More efficient removal of duplicates in recursive queries using the UNION compound operator. (check-in: 06c2db87 user: drh tags: trunk)
19:05
Only run the OP_OpenRead opcodes for a correlated subquery once, on the initial iteration. Keep the cursor open for subsequent runs. This was suppose to be a performance enhancement, but it is difficult to come up with a query where is makes a significant difference. Hence, the change is getting parked in a branch.

14:20
Add the SQLITE_NOTNULL P5 code for comparison operations - really a composite of SQLITE_NULLEQ and SQLITE_JUMPIFNULL. This flag indicates that NULL operands are not possible and raises and assert() if NULL operands are seen. Also omit an unnecessary scan of the sqlite_sequence table when writing into an AUTOINCREMENT table. (check-in: d2c047f3 user: drh tags: trunk)

Improvements to "NOT IN (SELECT ...)" processing. Only test for NULL values on the RHS on the first iteration, then remember the result. There has been logic to do this for year, but it didn't work right and ended up repeating the NULL test on every iteration. This inefficiency was found using the VDBE coverage testing tools.

15:13
Add OP_IdxGT and OP_IdxLE as distinct opcodes. Formerly these operations where done using OP_IdxGE and OP_IdxLT with the P5 flag set. But VDBE code is easier to read with distinct opcode names. Also change OP_SeekGe to OP_SeekGE, and so forth, so that the capitalization is consistent. The whole point of this change is to improve the readability of VDBE listings.

Separate out the code generators for the RHS of an IN operator and for SELECT/EXISTS expressions. (check-in: 61c34ba7 user: drh tags: subquery-codegen-refactor)
18:15
Use a new opcode, OP_OpenHash, to indicate that ephemeral tables can be unordered, rather than using the BTREE_UNORDERED bit in the P5 field. (check-in: 2997e181 user: drh tags: subquery-codegen-refactor)

In the Win32 VFS, the winSysInfo variable should be static. (check-in: 4a4dd371 user: mistachkin tags: trunk)
2014-02-04
23:45
Do not mark the ephemeral tables used to hold the RHS of IN clauses as unordered because the NGQP will use those ephemeral tables to help order the output. This is not an issue for standard SQLite since ephemeral tables there are always ordered, regardless of the hint. It only affects systems that substitute an alternative storage engine. (check-in: f2504089 user: drh tags: trunk)

2014-01-21
22:25
Change the recursive common table expression algorithm to use a queue instead of a pair of tables. Runs about 25% faster on the sudoku solver query. The OP_SwapCursors opcode is no longer required. The current implementation uses just a fifo, but the plan is to change it into a queue that will support ORDER BY and LIMIT in a recursive query. (check-in: b2671e11 user: drh tags: cte-via-queue)
15:04
Remove the undocumented requirement for applications that use an SQLITE_ENABLE_SQLLOG build to define a sqlite3_init_sqllog() function. (check-in: 5e43bf01 user: dan tags: trunk)

Fix a couple comment typos and one overly long line. No functional changes. (Closed-Leaf check-in: c57deced user: mistachkin tags: level-pseudocolumn)
00:19
Add support for the LEVEL pseudo-column in the recursive part of a common table expression. LEVEL has the value of 1 on the first iteration and successively larger integer values of subsequent iterations. It cannot have a table qualifier. Actual columns named "level" can still be accessed by including the table name qualifier. (check-in: cc1cb321 user: drh tags: level-pseudocolumn)
2014-01-20

Resolve table names within CTEs in the context in which the CTE is declared, not the context in which it is used. (check-in: a7323838 user: dan tags: trunk)
16:19
Add tests that verify that keywords WITH, WITHOUT, and RECURSIVE can still be used as table and column names. (check-in: 9ca18a01 user: drh tags: trunk)
15:27
Fix a compiler warning in selectPopWith(). (check-in: c8eb1163 user: drh tags: trunk)
15:15
Add support for common table expressions (WITH clauses). (check-in: 0171e3bb user: dan tags: trunk)

Fix some problems to do with WITH clauses and name resolution. (Closed-Leaf check-in: 6a549187 user: dan tags: common-table-expr)
11:48
Remove some code from resolve.c that was only required for recursive cte references in sub-queries. Also a stray "finish_test" command in pagerfault.test. (check-in: f68c6c4d user: dan tags: common-table-expr)
2014-01-16
22:40
Add the ability for the authorizer callback to disallow recursive queries. (check-in: 9efc120a user: drh tags: common-table-expr)

Allow only a single recursive reference in a recursive CTE. Also require that this reference is not part of a sub-query. (check-in: a296b733 user: dan tags: common-table-expr)
15:31
Always use available indices to optimize LIKE operators even if the pattern of the LIKE operator has a COLLATE modifier. This fixes an ineffiency that was introduced into 3.7.15 by check-in [8542e6180d4] on 2012-12-08. (check-in: 16bd5478 user: drh tags: trunk)
10:58
Disable the flattening optimization if the parent query is the recursive part of a recursive CTE and the sub-query is a compound query. (check-in: 6bfa387e user: dan tags: common-table-expr)

Disable automatic indices on recursive CTE references. (check-in: 28aa6db8 user: dan tags: common-table-expr)
18:12
When resolving names, consider a reference to a recursive CTE column as equivalent to a reference to the outermost name-context. This ensures that correlated sub-queries are correctly identified as such. (check-in: 61be2da0 user: dan tags: common-table-expr)
15:27
Return an error if a CTE specifies a different number of columns than its SELECT statement returns. (check-in: 9a514b50 user: dan tags: common-table-expr)

Parse common table expressions. But do not do anything with them (yet). (check-in: da98b720 user: drh tags: common-table-expr)
12:52
In LEMON, limit the size of the grammar file to 100MB. This ensures that the program will never experience integer overflow. To be doubly sure, use calloc() instead of malloc() when allocating arrays. (check-in: 29ba458d user: drh tags: trunk)
03:54
Optimizations to the SQL language grammar that result in a small size reduction and speed increase. (check-in: cb5d1f83 user: drh tags: trunk)
03:27
Add the "%token_class" directive to the LEMON parser generator. This opens up the possibility of simplifying the parser. Also remove all calls to sprintf(), strcpy(), and strcat() from LEMON to avoid compiler warnings on OpenBSD. (Aside: It is this change to avoid harmless compiler warnings that was the cause of the reason spat of bugs.) (check-in: 8eb48c04 user: drh tags: trunk)

Add the usual "fts3" prefix to new static method setEstimatedRows() in fts3.c. This fixes a problem when compiling the amalgamation, as the r-tree module also contains a static method named setEstimatedRows. (check-in: d6fcfc88 user: dan tags: trunk)
19:27
Avoid redundant register loads during index key generation when doing a DELETE or INTEGRITY_CHECK on a table with multiple indices. (check-in: 8f6e6149 user: drh tags: trunk)

Improvements to the column-cache for nested AND/OR operators. (check-in: 4e725f53 user: drh tags: trunk)
14:46
Have FTS assign extremely high costs to plans that feature unusable MATCH constraints. This discourages the planner from choosing such plans, which lead to "unable to use function MATCH in the requested context" errors. (check-in: fa8be488 user: dan tags: trunk)
14:42
Instead of having the planner ignore plans with unusable MATCH constraints, have FTS assign extremely high costs to such plans in order to discourage the planner from using them. (Closed-Leaf check-in: 24f84b38 user: dan tags: avoid-unusable-match)
14:16
Have the planner detect cases where a MATCH constraint is applied to a virtual table, and ignore any plans that do not allow the virtual table implementation to implement the MATCH filtering. (check-in: 19f3208b user: dan tags: avoid-unusable-match)

Be more aggressive in optimizing constant conditional expressions. (check-in: b7e39851 user: drh tags: trunk)
2014-01-01
15:18
Try to detect process ID changes due to fork() calls in os_unix.c and reset the PRNG when a process ID change is detected. (check-in: e1eba1fb user: drh tags: trunk)
14:00
Enhance sqlite3_randomness(N,P) such that it resets the internal PRNG if N is less than 1. Subsequent calls to sqlite3_randomness() will reinitialize the internal PRNG by calling the xRandomness() method of the default VFS. (check-in: a221aa82 user: drh tags: trunk)

Avoid compiler warnings by only enabling sqlite3ErrName() when SQLITE_TEST is defined. (check-in: 862228e5 user: drh tags: trunk)
16:06
Fix harmless compiler warnings in FTS4. This involved corrupting Martin Porter's beautifully written and elegant stemmer code, making it a little less beautiful and a little less elegant. Today is a sad day. But the warnings from GCC grow increasingly verbose and irksome with each new release and so something had to be done. (check-in: df056798 user: drh tags: trunk)

Fix the ".echo on" dot-command of the shell so that it echos comments in addition to SQL statements and dot-commands. Add the --explain option to speedtest1 so that the output can be piped into the command-line shell to show nicely-formated VDBE code for the entire test. (check-in: 96397263 user: drh tags: trunk)

Do not inject OOM faults into SQLITE_FCNTL_COMMIT_PHASE_TWO file-control invocations. It causes problems for test scripts. (check-in: 8eb28d23 user: dan tags: trunk)
16:26
Make sure errors encountered while initializing extensions such as FTS4 get reported out from sqlite3_open(). This fixes a bug introduced by check-in [9d347f547e7ba9]. Also remove lots of forgotten "breakpoint" commands left in test scripts over the years. (check-in: ca3fdfd4 user: drh tags: trunk)
14:34

Performance optimizations in the pager_write() routine of pager.c. (check-in: bc5febef user: drh tags: trunk)
19:48
Reduce the number of calls to the subjRequiresPage() routine inside of pager. (check-in: e50ff39a user: drh tags: trunk)
19:35
Create and use a new pager interface sqlite3PagerUnrefNotNull() that works just like sqlite3PagerUnref() but guarantees that its argument is not a NULL pointer. (check-in: e00f37e2 user: drh tags: trunk)
18:50
Enhance the pcache1PinPage() routine so that it called much less often and runs much faster in the cases when it is actually called. (check-in: a845779c user: drh tags: trunk)
16:42
Avoid unnecessary calls to sqlite3_free() from within sqlite3VXPrintf(). (check-in: e2a8b280 user: drh tags: trunk)

2013-12-11
15:47
Add the SQLITE_FCNTL_SYNC and SQLITE_FCNTL_COMMIT_PHASETWO file-controls and have the pager call them at appropriate times. This is needed in order to enable ZIPVFS to do multi-file atomic commits. (check-in: 552f94d5 user: drh tags: trunk)

Fix a bug in the shell ".import" command: Do not end the field when an escaped double-quote occurs at the end of a CRNL line. (check-in: 5e239ecd user: drh tags: trunk)
12:02
Remove an unreachable conditional inserted by the previous check-in. (check-in: 3e1d55f0 user: drh tags: trunk)
11:03
Have the crash-test infrastructure code in test6.c read and write the 512-byte block containing the pending-byte lock as normal. Earlier versions did not access this part of the file in order to avoid triggering an assert in os_unix.c. But the assert() has since been removed. And not reading/writing this part of the file causes problems for multiplexor tests. (check-in: fdc3f3fa user: dan tags: zipvfs-multifile-commit)

Fix harmless compiler warning. (check-in: 2525296d user: mistachkin tags: trunk)
00:59
Do not run the tool/vdbe-compress.tcl script that generates the vdbeExecUnion object that reduces the size of the sqlite3VdbeExec() stack frame unless the SQLITE_SMALL_STACK compile-time option is specified as on of the OPTS in the makefile. The vdbeExecUnion object gets in the way of C-compiler optimizer and results in slightly slower code. (check-in: 4d078147 user: drh tags: trunk)
2013-12-10

Modify the way some internal file-controls are invoked. In order to support multi-file transactions in the zipvfs extension. (check-in: 32fb1784 user: dan tags: zipvfs-multifile-commit)
19:25
Minor performance optimizations in pager.c. (check-in: ba9eef5f user: drh tags: trunk)

Fix an incorrect test number in the output of the speedtest1.c program. No changes to the test algorithms. (check-in: fbfc075a user: drh tags: trunk)
03:07
Avoid unnecessary (no-op) calls to sqlite3DbFree() from sqlite3VdbeMemRelease(). (check-in: 2d6dd7c2 user: drh tags: trunk)
02:32
Use memmove() rather than a home-made copy loop in insertCell() too. (check-in: a3d796b1 user: drh tags: trunk)
01:58
Use memmove() rather than a home-made copy loop in dropCell() of btree.c, for a size reduction and performance improvement. (check-in: 78e17068 user: drh tags: trunk)

Avoid unnecessary no-op calls from getAndInitPage() to btreeInitPage() in the btree.c logic. (check-in: 81f5ae13 user: drh tags: trunk)
00:47
Use putVarint32() instead of putVarint() for a quantity that can never exceed 2GiB - 1. (check-in: 6996fb34 user: drh tags: trunk)
2013-12-08
23:33
Another simplification to the OP_MakeRecord opcode, making it slightly faster and very slightly smaller. (check-in: f2f5a3ce user: drh tags: trunk)

23:35
Do not allow cursor hints to use expressions containing subqueries. This change fixes the problem seen in the previous check-in. (check-in: bfefc575 user: drh tags: cursor-hints)
20:39
If the SQLITE_ENABLE_CURSOR_HINTS macro is defined, then invoke the sqlite3BtreeCursorHint() interface to provide hints to the storage engine about rows that need not be returned. Hints can be disabled using SQLITE_TESTCTRL_OPTIMIZATIONS with SQLITE_CursorHints (0x2000). Cursor hints are not used by the built-in storage engine of SQLite but might be useful to applications that provide their own storage engine. The current code is work-in-progrss and contains bugs. (check-in: 3a9bec52 user: drh tags: cursor-hints)
17:01
Increase the version number to 3.8.3. (check-in: 23d00f22 user: drh tags: trunk)
16:56
At the start of each journaled write transaction, check to see if the database file has been moved, and if it has refuse to start the transaction, returning an SQLITE_READONLY_DBMOVED error code. Writing to a moved or renamed database is still allowed when journal_mode is OFF or MEMORY. (check-in: 369a23e0 user: drh tags: trunk)
16:45
Back out the new device capability. The determination of whether or not a file has moved is now done strictly using a file-control. (Closed-Leaf check-in: 9c59f5af user: drh tags: detect-moved-db)

Add additional test cases and requirements evidence marks for WITHOUT ROWID. (check-in: b408d788 user: drh tags: trunk)
2013-11-26
23:27
Make sure the update hook is not invoked for WITHOUT ROWID tables, as the documentation specifies. This bug was found while adding requirements marks, so a few extraneous requirements marks are included in this check-in. (check-in: 0978bac6 user: drh tags: trunk)
22:46
Add requirements test cases for determining when an expression is true and when it is false. (check-in: 838654e5 user: drh tags: trunk)

15:45
Change the REAL-to-INTEGER casting behavior so that if the REAL value is greater than 9223372036854775807.0 then it is cast to the latest possible integer, 9223372036854775807. This is sensible and the way most platforms work in hardware. The former behavior was that oversize REALs would be cast to the smallest possible integer, -9223372036854775808, which is the way Intel hardware works. (check-in: 6f53fc71 user: drh tags: trunk)

Add the --scratch parameter to speedtest1. Improved error messages when misconfiguring memory parameters in speedtest1. (check-in: 8f3c767a user: drh tags: trunk)
00:46
The MEMSYS5 algorithm does not have to return the block with the lowest address. Any block of the appropriate size will do. Use the first block found on the freelist for the appropriate size for a performance improvement. (check-in: 12e612e8 user: drh tags: trunk)
2013-11-23
22:45
A much simpler fix is to simply change MEMSYS5 so that it takes any free block of the appropriate size (the first on the list of free blocks) rather than searching for the one with the smallest address. This is also faster than using the min-heap algorithm. Need to research to verify that the allocator still satisfies the Robson proof, however. (Closed-Leaf check-in: 8191b512 user: drh tags: memsys5-performance)
21:30
Use a heap-based primary queue rather than a linked list to store the available free blocks of each size in MEMSYS5, since this provides faster access to the first available block. (Closed-Leaf check-in: 7d2cdfad user: drh tags: memsys5-performance)

19:34
Change the "idx" name of the primary key index for WITHOUT ROWID tables in sqlite_statN statistics tables to be the name of the table rather than the fabricated index name (ex: sqlite_autoindex_xyz_1). This makes it consistent with sqlite_master table. (check-in: 4ee4d310 user: drh tags: omit-rowid)

2013-10-22
18:01
The Index object now has nKeyCol and nColumn. nColumn is the total number of columns and nKeyCol is the number of key columns. Currently these always differ by one. Refactor aiColumn[] to be of type i16 instead of int. (check-in: a106ce86 user: drh tags: omit-rowid)

Add a procedure to handle the messy details of allocating an Index object from the heap. (check-in: 45efc94f user: drh tags: omit-rowid)
10:23
Extra backwards-compatibility tests verify that UNIQUE and PRIMARY KEY indices are created in the correct order. Other backwards-compatibility tests already cover this, but it does not hurt to double up. (check-in: 5ca0ea2e user: drh tags: omit-rowid)
01:18
Previous refactor is not going to be helpful because implied indices must be created in the same order that they appear in the CREATE TABLE statement for backwards compatibility. This is a much smaller change to clean up a few loose ends. (check-in: 824b549f user: drh tags: omit-rowid)

Add ext/misc/vfslog.c, a VFS shim for unix that keeps a log of method calls made by SQLite. (check-in: 24a827b8 user: dan tags: trunk)
12:38
Estimate row sizes for tables and indices and use those estimates during query planning. Enhance the index_info pragma to show the estimated row sizes and to show the estimated row size for the main table as well. Allow an alternative row size estimate to be specified in the sqlite_stat1 table. (check-in: d27b88b8 user: drh tags: trunk)
2013-10-09
19:07
Make sure the correct printf format is used for type tRowcnt regardless of whether 32-bit or 64-bit row counts are specified at compile-time. (Closed-Leaf check-in: e97d7d30 user: drh tags: row-size-est)
2013-10-08

20:42
Rollback some of the previous changes in the branch such that the estimated row sizes are now only used as a tie-breaker for index scans. (check-in: 65553ff3 user: drh tags: row-size-est)
20:01
Use #ifdefs to omit unused code in the columnType() routine depending on compile-time options. (check-in: 3fd5e332 user: drh tags: row-size-est)

Fix compilation issue with MSVC. (check-in: 36d64dc3 user: mistachkin tags: trunk)
17:32
Multiply all cursor step cost estimates by the estimated size of the row in bytes, in order to get the query planner ot make use of estimated row sizes. This check-in uses magic numbers in a few places (for example, estimates of the size of output rows) and needs lots of refinement. Consider this a proof-of-concept only. (check-in: cb34cfe5 user: drh tags: row-size-est)
16:53
Try to remember statistics from ANALYZE using LogEst instead of u64. (Leaf check-in: 8e78557a user: drh tags: log-stats)

Fix an issue in the test8.c test module that arises because of the change to PRAGMA index_list(). Remove an unused local variable. (check-in: 029430c5 user: drh tags: row-size-est)
19:18
Completely remove the iScanRatio field. The PRAGMA index_list(TABLE) command shows the estimated row size in the forth column. It also generates a row for the table with an index name of NULL. The query planner still does not take row size estimates into account - that is the next step. (check-in: 8b4aa0c7 user: drh tags: row-size-est)
18:32
Improvements to the LogEst command-line tool used to convert between ordinary numbers and the LogEst representation. (check-in: 5252aeb6 user: drh tags: row-size-est)
18:16
Begin an experimental refactoring to estimate the average number of bytes in table and index rows and to use that information in query planner. Begin by renaming WhereCost to LogEst and making that type and its conversion routines available outside of where.c. (check-in: 66c4a251 user: drh tags: row-size-est)
02:56
In the index_list pragma, make sure the "r" column is the same on output as it was on input in the sqlite_stat1 table. (Closed-Leaf check-in: de78250a user: drh tags: index-scan-rate)

Further refinements of the index scanning speed logic. (check-in: e5d9371d user: drh tags: index-scan-rate)
18:17
If an "INSERT INTO ... SELECT" can use the xfer optimization, pass the OPFLAG_BULKCSR hint to btree cursors used to update indices. This results in a tighter key packing. (check-in: 087af29e user: dan tags: trunk)
15:58
Fix test cases so that they work when the query planner uses index size estimates to determine whether or not to try an covering index scan. (check-in: 2f394de8 user: drh tags: index-scan-rate)
15:30
Improved estimates of the relative speed of index scans based on declared datatypes of columns in the table. Add "r" column to PRAGMA index_info, showing the estimated relative scan rate. (check-in: 07462bb6 user: drh tags: index-scan-rate)

20:28
Merge latest trunk changes. (Closed-Leaf check-in: 24aa20da user: dan tags: fts4-docid-range-constraints)
19:27
Allow FTS4 multi-token phrases to use a combination of in-memory and incrementally loaded doclists. This allows phrases to (partially) benefit from incremental doclists without disabling the deferred token optimization. (check-in: f6819c5f user: dan tags: fts4-docid-range-constraints)
19:21
Experimental branch allowing different postulated scan rates for each index. (check-in: d59d97b0 user: drh tags: index-scan-rate)
15:39
The sqlite3FixInit() routine cannot fail. So change the return type from "int" to "void". (check-in: 500c5932 user: drh tags: trunk)
14:08
Rework the PRAGMA implementation to only call sqlite3ReadSchema() from a single place, based on a flag in the pragma table, rather than separately from each case which needs the schema. (check-in: 8338232a user: drh tags: trunk)
12:29
Return an error if an attempt is made to create a trigger with an SQL variable embedded within it. If such a variable reference is found within a trigger definition loaded from the sqlite_master table, silently replace it with a NULL. (check-in: f35f6ae3 user: dan tags: trunk)

Merge trunk changes with this branch. (check-in: 65d9c6fa user: dan tags: fts4-docid-range-constraints)
20:02
Allow multi-token phrases to load doclists from the database incrementally. This allows queries that feature such phrases to benefit from the "docid<?" optimization. (check-in: ea543f08 user: dan tags: fts4-docid-range-constraints)

When estimating the number of rows scanned using data from the sqlite_stat4 table, avoid allocating UnpackedRecord and KeyInfo structures until they are definitely required. (check-in: 353950a5 user: dan tags: sqlite_stat4)
14:18
Add a guard #ifndef to test_intarray.h to prevent harm if it is #included more than once. Add a comment on the closing #endif of the guards on sqlite3.h and test_multiplex.h. (check-in: 0ad83ceb user: drh tags: trunk)

14:01
Clean up the input reader in the command-line shell for improved legibility and performance. (check-in: 2b1743d6 user: drh tags: trunk)
07:45
More than double the speed of the resolveP2Values() routine in vdbeaux.c by moving from an extended if-else on every opcode to a switch. Opcodes are reordered in mkopcodesh.awk to put the switched opcodes close together, for additional performance and to reduce code footprint. (check-in: 924f7e4d user: drh tags: trunk)

For the vtshim module, always zero out the xChildDestroy function pointer after calling it. (check-in: 240f7252 user: mistachkin tags: trunk)
19:11
Factor all KeyInfo object allocations into a single function: sqlite3KeyInfoAlloc(). Always allocate enough space so that sqlite3VdbeRecordCompare() can avoid checking boundaries and hence run faster. (check-in: 7301bedd user: drh tags: trunk)
19:04
Modify the vdbe code generated by ANALYZE to use fewer memory cells and cursor slots. (check-in: 4a51cf28 user: dan tags: sqlite_stat4)
18:00
Use N separate cursors when scanning an index with N columns to collect sqlite_stat4 data. This fixes a problem with collecting incorrect nEq values from multi-column indexes. (check-in: 3a71afe6 user: dan tags: sqlite_stat4)
15:32
Improve performance of sqlite3VdbeRecordCompare() by using an approximation that might give false negatives and only running the more expensive exact subexpression if the approximation fails. (check-in: 28979dcd user: drh tags: trunk)
12:31
Add a missing '#include "tcl.h"' to test_rtree.c. (check-in: 4b8b426f user: drh tags: trunk)

2013-08-01
22:27
Fix the CREATE INDEX statement so that trying to create a TEMP index on a non-TEMP table throws an error rather than segfaulting. (check-in: e3c8935f user: drh tags: trunk)
22:26
Fix an incorrect expected result in a test case in corruptG.test. (check-in: 6913831a user: drh tags: trunk)
20:26
Fix a potential buffer overread in sqlite3VdbeRecordCompare() when a serial_type specifies a field that starts in bounds but is much too large for the allocated buffer. Mostly harmless. The overread is unlikely to go more than one or two bytes past the end of the buffer. (check-in: e436b2f4 user: drh tags: trunk)
19:17
Make sure signed integer overflow does not cause a segfault while attempting to read a corrupt database where the header size varint on a record is larger than the maximum 32-bit signed integer. (check-in: c3baca99 user: drh tags: trunk)
17:43
Add test case for the problem fixed by [127a5b776d]. (check-in: 65816718 user: dan tags: trunk)
17:21
An improved method for avoiding the use of the STAT3 samples to compute the estimated number of outputs when the left-most index is equality constrained. This check-in undoes the previous fix and applies a new one. (check-in: 127a5b77 user: drh tags: trunk)
16:52
Avoid using left-most column STAT3 samples if the left-most column has an equality constrain and there are inequality constraints on the second column. (check-in: 31b4e63b user: drh tags: trunk)
16:02
Fix bug in the logic that determines the end of a CREATE INDEX statement. Added a VACUUM test case that exposed the bug. (check-in: 2e3df0bc user: drh tags: partial-indices)

Limit the number of memset() calls used when determining a temporary file name on Windows. Also, fix a harmless compiler warning. (check-in: 136fc293 user: mistachkin tags: trunk)
23:22
Add logic to the query planner to only use partial indices if the WHERE clause constrains the search to rows covered by the partial index. This is just infrastructure. The key routine, sqlite3ExprImpliesExpr(), is currently a no-op so that partial indices will never be used. (check-in: 8ca3eac1 user: drh tags: partial-indices)
22:39
Slight modifications to path name translation handling for Cygwin. (check-in: 33ba1f4c user: mistachkin tags: trunk)

Use a new error code to represent a failure to get the configured temporary directory on Windows. (check-in: c93d891b user: mistachkin tags: trunk)
19:55
The MAX_PATH constant in windows is measured in characters, so multiple by 3 to get the number of bytes assuming worst-case UTF8 pathnames. (check-in: bb06e157 user: drh tags: trunk)
19:05
Resolve names in CREATE INDEX WHERE clauses and detect errors. Disallow expressions that contain variables, subqueries, or functions. The expression is still not used for anything, however. still unused. (check-in: f2aa7842 user: drh tags: partial-indices)
18:12
Here begins an experimental branch for exploring the idea of a partial index. This check-in is able to parse a WHERE clause on a CREATE INDEX statement, but does not actually do anythingn with that WHERE clause yet. (check-in: 6794b2dc user: drh tags: partial-indices)

Comment and preprocessor macro cleanup. (check-in: c0809b5e user: drh tags: trunk)
13:51
In main.mk, always recompile vdbe.o and parse.o first, since changes to either parse.y or vdbe.c will cause all files to be recompiled and if there are syntax errors in vdbe.c or parse.y we want to hit them early in the compile process. (check-in: a94a66d1 user: drh tags: trunk)

22:28
Get the new URI logic working for Windows. (Closed-Leaf check-in: 0165789f user: drh tags: uri-enhancement)
20:54
Update the URI filename parser to allow (and ignore) authority names in unix and to pass the authority through to the OS on windows, as this appears to be what web-browsers are doing. (check-in: 74c12dee user: drh tags: uri-enhancement)

17:12
Ensure that all auxiliary data registered by calls to sqlite3_set_auxdata() is destroyed when the VM is halted. Partial fix for [406d3b2ef9]. DRH adds: Stray text accidentally inserted into vdbe.c just prior to the commit breaks the build. (check-in: 71effa59 user: dan tags: typo)
14:50
Fix a 8-byte alignment problem in the query planner that might cause problems on sparc when compiled with -m32. (check-in: 5dcffa67 user: drh tags: trunk)

Merge recent trunk changes (such as the query_only PRAGMA, the defer_foreign_keys PRAGMA, and the SQLITE_DBSTATUS_DEFERRED_FKS parameter to sqlite3_db_status()) into the sessions branch. (check-in: 8dfc0b78 user: drh tags: sessions)

15:03
Add the "defer_foreign_keys" pragma and the SQLITE_DBSTATUS_DEFERRED_FKS value for sqlite3_db_status(). This is a cherry-pick of a sequence of five checkins in the sessions branch between [1d44e5d3c2] and [d39e65fe70]. (check-in: 527121ac user: drh tags: trunk)
13:49
Remove the undocumented sqlite3_foreign_key_check() API and replace it with sqlite3_db_status(db, SQLITE_DBSTATUS_DEFERRED_FKS, ...). Add test cases for the new functionality. (check-in: d39e65fe user: drh tags: sessions)

Drop any existing mapping of the database file when exiting the pager "error state", as it may at this point be too large for the database file. Do not invoke file-control MMAP_SIZE if the database file handle does not support xFetch and xUnfetch (on the grounds that xUnfetch(0) calls to invalidate the mapping cannot be made).

2013-07-03
19:53
Experimental change to the handling of foreign key constraint violations when applying a changeset: all foreign keys, immediate and deferred, are deferred until the end of the transaction (or sub-transaction) opened by the sqlite3changeset_apply(). A single call to the conflict-handler (if any) is made if any FK constraint violations are still present in the database at this point.

02:05
Attempt to disable inner loops of a join that do not generate output. This does not work, since the inner loops might run zero times and thus inhibit all output.

19:28
The expected result in a test case can be of the form "*glob*" or "~*glob*" to match or not match the GLOB pattern. This is useful for matching EXPLAIN QUERY PLAN output that contains regular expression syntax characters like "?", "(", and ")". (check-in: a3b4e261 user: drh tags: nextgen-query-plan-exp)
17:43

01:40
Cause the mmap_size PRAGMA to immediately change the mmap space if the database connection is already active. In particular, reducing mmap_size will immediately free up process address space. (check-in: 76117792 user: drh tags: trunk)
2013-05-22
20:49

16:41
In test file test_syscall.c, include sqliteInt.h before any tcl or system include files. This ensures that the magical defines in sqliteInt.h really do enable large file support (and set things up so that sizeof(off_t)==8). (check-in: 0f355bb1 user: dan tags: trunk)

Expand scope of the SQLITE_MAX_MMAP_SIZE define for the Win32 VFS. (check-in: f4b8faab user: mistachkin tags: trunk)
17:03
Refactoring the mmap interface. The controlling pragma is now "mmap_size" instead of "mmap_limit". Also change SQLITE_CONFIG_MMAP_LIMIT and SQLITE_FCNTL_MMAP_LIMIT to SQLITE_CONFIG_MMAP_SIZE and SQLITE_FCNTL_MMAP_SIZE, respecctively. The default mmap_size is now always 0, meaning that memory mapped I/O is off by default. There is a new compile-time option SQLITE_MAX_MMAP_SIZE that determines a hard upper bound on the mmap_size. Setting SQLITE_MAX_MMAP_SIZE to zero disables the memory-mapped I/O logic and causes it to be omitted from the build. An extra argument is added to SQLITE_CONFIG_MMAP_SIZE that can optionally lower the SQLITE_MAX_MMAP_SIZE at start-time. The SQLITE_MAX_MMAP_SIZE is zero for platforms where we know that it does not work, meaning that it cannot be turned on by mistake on those platforms. (check-in: ea1404a1 user: drh tags: trunk)

Allow the "a=?1 OR a=?2" to "a IN (?1,?2)" transformation to work on virtual tables again. This was formerly restricted because virtual tables could not optimize IN terms. (See check-in [fad88e71cf195e].) But IN terms are now used by virtual tables (as of check-in [3d65c70343]) so the restriction can now be removed. (check-in: a917c1f0 user: drh tags: IN-with-ORDERBY)

2012-01-28
21:08
Update the .dump command of the command-line shell so that it (1) avoids putting the semicolon of a DDL statement on the same line as a comment, (2) avoids long expression, even when dumping a table with many columns, and (3) avoids unnecessary quoting of the table name. This fixes tickets [c04a8b8a4f] and [232637c465]. Shell change only; no changes to the SQLite core. (check-in: e6eea8d5 user: drh tags: trunk)

2012-01-24
10:08
Changes to the async-io module so that the xFileControl method returns SQLITE_NOTFOUND when a file-control is not recognized and so that it adds the second nul-terminator byte to filenames passed to the xOpen method of the underlying VFS. (check-in: 7036886e user: dan tags: trunk)
2012-01-20
15:05

00:42
In the multiplexor routine that determines the size of an overflow file, return 0 and leave the error code unchanges if there were prior errors. This prevents some I/O errors from going unreported in nx-devkit tests. (check-in: 6da0821a user: drh tags: trunk)

Make sure filenames handed to the VFS by the fake_big_file test procedure are double-zero terminated. (check-in: d0a86860 user: drh tags: trunk)
2012-01-10
23:18
Only require double-zero terminators on database filenames, not any every files supplied to the xOpen method. This backs out [2544f233f1]. Also refactor the fillInUnixFile() routine in os_unix.c to reduce the number of parameters. (check-in: cb774b26 user: drh tags: trunk)
17:59
Refactor sqlite3OsFileControlNoFail() into sqlite3FileControlHint(). (check-in: 722735a4 user: drh tags: trunk)
17:28
Avoid passing strings with a single nul-terminator (two are required) to the VFS xOpen() method from within the code that checks to see if a master-journal file may be safely deleted. (check-in: 2544f233 user: dan tags: trunk)
16:56
Add function sqlite3OsFileControlNoFail(), which is the same as sqlite3OsFileControl() except that it does not simulate OOM errors. This saves adding calls to the BenignMalloc() functions around each of the invocations of sqliteOsFileControl() that ignore the return code. (check-in: af59b182 user: dan tags: trunk)
16:40
Check the return code from sqlite3OsFileControl() in sqlite3BtreeCopyFile() and report any errors that it generates. (check-in: 7f852ac6 user: drh tags: trunk)

2012-01-07
15:17
Fix a bug in lemon in computation of which non-terminals can generate an empty string. This bug and the fix make absolutely no difference for the grammar used by SQLite, but it can make a difference when lemon is used in other grammars. (check-in: ce32775b user: drh tags: trunk)
2012-01-06
13:58
Add missing finish_test to the end of the zerodamage.test module. Disable the zerodamage module if virtual tables are omitted from the build. (check-in: d2a5685b user: drh tags: trunk)

21:19
Make sure the name of the shared memory file has two zero-terminators in the UNIX VFS, so that sqlite3_uri_parameter() will work correctly on that name. (check-in: 3d088ba5 user: drh tags: trunk)
18:33
Fix an incorrect assert() on the sqlite3FileSuffix3() function. (check-in: 24db54bd user: drh tags: trunk)
16:07
Change the unix VFS so that it ignores all but the least-significant bit of the syncDir flag to xDelete. Add an assert to prove that the core only ever uses that one bit. (check-in: e75fd3b2 user: drh tags: trunk)
13:02
Merge all of the latest trunk changes into the sessions branch. (check-in: a9bcb432 user: drh tags: sessions)

2012-01-02
18:20
Remove the code that attempts to find the sector size from the OS and hardcode the xSectorSize methods of the unix and windows VFSes to return SQLITE_DEFAULT_SECTOR_SIZE, which is now set to 4096 unless overridden. (check-in: 03d8362c user: drh tags: trunk)
18:00

(check-in: c83627b7 user: drh tags: statvfs)
2011-12-20
22:18
Remove the code that tries to detect OOO header writes on a WAL recovery. The code is made obsolete by syncing the WAL header. (check-in: 7ac713a1 user: drh tags: statvfs)
20:13
Refactor the sqlite3WalFrames() routine for clarity of presentation. Do the padded transaction sync as the write pointer crosses the final sector boundary instead of at the end, for efficiency. Always sync the WAL header immediately after it is written. (check-in: 92c73b42 user: drh tags: statvfs)
13:13
Assert that the isCommit parameter to sqlite3WalFrames() is zero if and only if the nTruncate parameter is zero. (check-in: 979daf92 user: drh tags: trunk)

Some fixes to the test suite so that it works with ZERO_DAMAGE set to true. Still lots more problems remain. (check-in: 41891b23 user: drh tags: statvfs)
2011-12-17
20:02
For improved clarity of presentation, refactor some of the code associated with ZERO_DAMAGE and sector-size. (check-in: 1dde96c9 user: drh tags: statvfs)
19:49
Add SQLITE_IOCAP_ZERO_DAMAGE and enable it for both unix and windows. Use this device characteristic to reduce the required work in journaling. A side effect is that this changes the default page exists back to 1024 even with the use of statvfs(). (check-in: a0be6ea4 user: drh tags: statvfs)
16:25
Fix a bad #endif with the previous check-in on this branch. (check-in: 915713ff user: drh tags: statvfs)
16:09
Add support for statvfs() in os_unix.c, for determining the sector size. This causes many TCL test failures under Linux. (check-in: e0d44450 user: drh tags: statvfs)
13:45
Merge in changes that cause the first sector of the WAL file to be synced when the WAL restarts. This is a fix for the power-loss corruption problem described in ticket [ff5be73dee086] (check-in: 44ca4d12 user: drh tags: trunk)
08:10
Add tests to walcrash3.test. (check-in: d7688042 user: dan tags: trunk)

Enhance the WAL header sync so that it honors the various synchronous pragmas, settings, and device characteristics. (Closed-Leaf check-in: 9799241f user: drh tags: wal-header-sync)
19:34
Proposed changes that ensure that the WAL header is written prior to the first commit mark. (check-in: 91d0437c user: drh tags: wal-header-sync)
17:01
Add code for a test that was failing before the persistent-wal related changes of [09ccc4a1be]. (check-in: 49d21ce5 user: dan tags: trunk)
15:38
Merge the fix for [a1fa75cbdd02] from the experimental branch. Also fix the persistent-wal mode feature of truncating the WAL on close so that it always truncates the WAL to zero bytes. (check-in: 09ccc4a1 user: drh tags: trunk)

05:09
Fix a potential infinite loop (inserted by the previous check-in) on the multiplexWrite() method of the multiplexor. (check-in: 022bf427 user: drh tags: nx-devkit)
04:57
The xTruncate method for the multiplexor now changes surplus overflow files to zero-length by default. Or if the "truncate" query parameter is used, it actually deletes the surplus overflow files. This allows VACUUM to shrink the database again. (check-in: 5aefef04 user: drh tags: nx-devkit)
01:30
Call sqlite3_log() with an appropriate message if unable to find a unique master-journal filename. (check-in: e9177f7d user: drh tags: nx-devkit)
01:21
A better solution to being unable to find a unique master-journal filename: just delete an existing master-journal and reuse it. (check-in: 2685c2b9 user: drh tags: nx-devkit)
00:33
Make sure the antipenultimate character of master-journal filenames is a "9" in order to avoid collisions with other files in 8+3 filename mode. Also, limit the number of attempts at finding a unique master-journal filename. (check-in: 34a04836 user: drh tags: nx-devkit)
2011-12-15
17:44
Add stdio support to the quota VFS. (check-in: 322bd15f user: drh tags: trunk)
17:42
Use _commit() rather than FlushFileBuffers() as a substitute for fsync() on windows. Also cast for C++ and add support for SQLITE_FCNTL_VFSNAME. (Closed-Leaf check-in: e85cfe9a user: drh tags: quota-stdio)
17:00
When deleting a file with the multiplexor VFS, also delete any overflow files that exist. (check-in: 3af1feaa user: dan tags: nx-devkit)
13:29
Make sure the chunksize in test_multiplex does not cause the pending byte to fall near the end of a chunk. Adjust the chunksize upward as necessary to prevent this. (check-in: e05f8a29 user: drh tags: nx-devkit)
11:45
Fix some problems with dropped error codes in multiplexOpen(). (check-in: 2d50f781 user: dan tags: nx-devkit)
02:22
In the multiplexor, do not try to delete overflow files that do not exist. And assume all but the last overflow file is the size of the chunk size. (check-in: a822a80d user: drh tags: nx-devkit)
2011-12-14
18:33
Merge the nx-devkit changes into trunk. This includes the new SQLITE_FCNTL_VFSNAME file-control. (check-in: da118e02 user: drh tags: trunk)

01:38
Improvements to comments. No code changes. (check-in: 08bbbd8e user: drh tags: nx-devkit)
00:37
Treat a zero return value from the Win32 APIs MultiByteToWideChar and WideCharToMultiByte as an error condition. (check-in: c65e5a36 user: mistachkin tags: trunk)
00:04
Harden the utf8-to-mbcs converter in the quota module against failures. (check-in: 1cda511d user: drh tags: quota-stdio)
2011-12-13
23:26
Enhancements to test_quota.c: Remove the external dependency on sqlite3_win32_utf8_to_msbc(). Add an extra parameter to quota_fflush() that will also do an fsync (or the equivalent). (check-in: 92f4188f user: drh tags: quota-stdio)
19:03
Add a hard limit to the number of chunks a multiplexed database may consist of if ENABLE_8_3_NAMES is defined. (check-in: 43a12640 user: dan tags: nx-devkit)
18:22
Change the SQLITE_EXTRA_INIT routine to take a single argument which is a pointer to a string. Call SQLITE_EXTRA_INIT with a NULL argument. Fixes to multiplexor to treat the VFS properly in corner cases. Fix the initialization of multiplex3.test. (check-in: 8e65b913 user: drh tags: nx-devkit)
16:40
Add extra tests for the multiplexor VFS. No changes to code. (check-in: c7de6f68 user: dan tags: nx-devkit)
15:37
Merge the nx-devkit changes into trunk. (check-in: 03a70c3d user: drh tags: trunk)
15:25
Update the multiplex.test script to conform to that found in the "experimental" branch off of trunk. (check-in: 2eb79efb user: drh tags: nx-devkit)
15:02
Move the multiplexor changes in the experimental branch (check-ins [255d21499b] and [199f52bced]) into the nx-devkit branch. (check-in: eb95d2f7 user: drh tags: nx-devkit)
12:10
This branch merged with nx-devkit and from there into trunk. Was: In the multiplexor, instead of generating a unique file-name when SQLite opens a temp file, allow the underlying VFS to generate a different temp file for each chunk. Given the changes to the xFileSize method, it is no longer necessary for the different chunks of a temp file to use the same base name. (Closed-Leaf check-in: 199f52bc user: dan tags: experimental)
11:15
Change the way IO errors are handled in the xFileSize method of the multiplexor VFS. Add test file multiplex3.test. (check-in: 255d2149 user: dan tags: experimental)
04:08
When an sqlite3_auto_extension() function fails, report back its actual error code, not the generic SQLITE_ERROR. (check-in: ce55f250 user: drh tags: nx-devkit)
02:41
When the multiplexor FileSize procedure fails to open the file, assume that the file is zero bytes in size. (check-in: dc8118cd user: drh tags: nx-devkit)
01:34
Add a compile-time shutdown procedure to be called by sqlite3_shutdown() to undo the effects of the compile-time initialization procedure. (check-in: c2ed86f5 user: drh tags: nx-devkit)
2011-12-12
20:01
Backport a minimal set of changes needed to get 8+3 filenames and the multiplexor shim playing well together. (check-in: c4e2ce48 user: drh tags: nx-devkit)
19:48
Fix os_unix.c so that, unless 8.3 filenames are actually in use, journal and wal file permissions are assigned correctly even if SQLITE_ENABLE_8_3_NAMES is defined. (check-in: 169e1229 user: dan tags: trunk)
19:47
Make sure the quota logic is usable as C++. (check-in: f4534bd3 user: drh tags: quota-stdio)

2011-12-11
22:44
In the multiplexor shim, when using 8+3 filenames, begin numbering journal overflow files with 101 instead of 001 to avoid name collisions with the main database file. (check-in: 05bf8a0b user: drh tags: trunk)

2011-12-09
18:06
Change the VDBE so that all registers are initialized to "Invalid" instead of NULL and report errors on any attempted read of an Invalid register. This will help prevent future bugs similar to [7bbfb7d442]. (check-in: 0064bab7 user: drh tags: trunk)

Remove an unnecessary initialization of Vdbe.aOnceFlag. (check-in: 421714da user: drh tags: uninit-vdbe-mem)
17:27
Take out the OP_JumpOnce opcode. Revert compound SELECT to use OP_IfNot, which is the correct behavior. Mark trigger registers as initially invalid. (check-in: 6a9fb47d user: drh tags: uninit-vdbe-mem)
16:59
Previous check-in broke auto-increment. This check-in appears to fix it. (check-in: 28ffd39c user: drh tags: uninit-vdbe-mem)

18:44
Add stdio-like I/O interfaces to the test_quota VFS. This is a prototype change for discussion and is mostly untested. This is an alternative to adding stdio-like I/O interfaces in the core. There is no guarantee that this code will make it into the trunk. If it does get to trunk, there could be many changes to the interface first. (check-in: bd3ce723 user: drh tags: quota-stdio)
02:32
Add a prototype implementation of stdio-like routines for accessing the VFS. This is intended as documentation. The code is untested.

13:04
Merge the read-only shared memory branch into trunk. After this merge, an unprivileged process can open WAL-mode databases owned by another user as long as a database connection with write permission exists on the database file and if the readonly_shm=1 URI query parameter is supplied. (check-in: 19084a66 user: drh tags: trunk)

15:39
Add an OP_VerifyCookie instruction to "CREATE XXX IF NOT EXISTS" commands. This way, if the specified database object existed when the statement was compiled but removed from the database before sqlite3_step() was called, the statement still works as expected (and creates the object). (check-in: b9dbd993 user: dan tags: trunk)
03:30
Back port the unordered-index-hack to the 3.7.2 branch. (check-in: 80353020 user: drh tags: branch-3.7.2)

When searching a list of freelist trunk pages looking for a specific page to allocate, avoid unnecessary journalling of the unchanged trunk pages towards the start of the list. (check-in: d03d63d7 user: drh tags: trunk)
14:05
Avoid running thread1.test or thread2.test if SQLITE_MUTEX_NOOP is defined. (check-in: 532ae32e user: dan tags: trunk)
10:09
Do not run multi-threaded Tcl tests if the library was built with SQLITE_MUTEX_NOOP defined. (check-in: e4e99606 user: dan tags: trunk)

22:05
Fix a performance regression: Keep two btree masks in each prepared statement; one for btrees used and another for btrees that require locks. Only try to lock the btrees identified by the second mask. (check-in: 614de91a user: drh tags: trunk)
19:15
Fix a benign inaccuracy in the os_unix.c SQLITE_FCNTL_SIZE_HINT code. (check-in: 61a6ccbe user: dan tags: trunk)

19:27
Simplifications to the sqlite3BtreeEnterAll() and LeaveAll() routines. Just have them call BtreeEnter and BtreeLeave() repeatedly rather than trying to be clever. (check-in: 51039b35 user: drh tags: trunk)
19:26
Simplifications to the sqlite3ResetInternalSchema() logic to eliminate unreachable branches. (check-in: a4c3ac98 user: drh tags: trunk)
18:34
Remove dead code from the OP_JournalMode opcode in the VDBE. This code seems to have been useless since [f88c6367d2] on 2010-08-07. (check-in: a89f24e2 user: drh tags: trunk)
17:31
Remove the mutex counter and the logic that attempts to verify that btree mutexes are held continuously. We are not making that assumption at this time. (check-in: 242ce7cf user: drh tags: trunk)
16:09
When committing a WAL transaction, do not write any pages to the WAL file with page numbers greater than the size of the database image in pages. (check-in: 311d0b61 user: dan tags: trunk)

Merge test_syscall.c fix from the trunk. (check-in: 1e1a23cc user: dan tags: schema-parse-refactor)
14:03

Suppress unused parameter warnings in sqlite3VdbeEnter() and related routines. (check-in: f8e98ab3 user: drh tags: trunk)
00:14
Remove the BtreeMutexArray object - use the Vdbe.btreeMask field to accomplish the same result. Add a generation counter to btree mutexes in order to assert that mutexes are never temporarily dropped over a range of instructions in order to do deadlock avoidance in some subroutine. Lock all btrees in any Vdbe program that uses OP_ParseSchema. (check-in: d81708f7 user: drh tags: trunk)
2011-04-03
18:19

16:50
When resetting any non-TEMP schema, also reset the TEMP schema since it might be holding references to the non-TEMP schema that just got reset. (check-in: 211d5dde user: drh tags: schema-parse-refactor)
16:28
Begin a series of changes designed to reduce the scope and frequency of invalidating schemas. Design goals are that the internal schema should never be deleted out from under a prepared statement that is running and that all prepared statements should be expired if the schema is invalidated. At the same time, minimize the number of schema invalidations. This change merely revises the sqlite3ResetInternalSchema() function to use -1 as the wildcard for "all" rather than 0, so that we can reset the main schema independently of all the others. (check-in: 6a8ad6e3 user: drh tags: schema-parse-refactor)
09:44
Fix a race condition in OP_ParseSchema. (check-in: 71a799b0 user: dan tags: trunk)

17:53
Change analyze7.test so that it works without SQLITE_ENABLE_STAT2 defined. (check-in: 9415201c user: dan tags: trunk)
16:50
When simulating an error in the close() system call, close the file descriptor anyway. Otherwise long running tests leak too many file-descriptors and crash. (check-in: 81ddbf43 user: dan tags: trunk)
15:43

15:15
Ensure that it is not possible to add a column to a system table using ALTER TABLE. (check-in: d9707ef8 user: dan tags: trunk)
14:26
Merge the ANALYZE-index enhancement into trunk. (check-in: 7e237aea user: drh tags: trunk)

15:40
Fix a problem whereby following an IO error in CommitPhaseTwo() of a multi-file transaction the b-tree layer could be left in TRANS_WRITE state, causing problems later on. (check-in: dbe569a0 user: dan tags: trunk)
15:00
If the keyword "unordered" appears at the end of the SQLITE_STAT1.STAT column for an index, then use that index for equality lookups only, never for range queries or sorting. (Closed-Leaf check-in: 3b964155 user: drh tags: unordered-index-hack)
14:08
Further improvements to the fuzzer. It still is not quite working. Pausing to work on other things.... (check-in: 5f2f2fce user: drh tags: word-fuzzer)
10:04
Fix a problem in the unix VFS implementation of xNextSystemCall(). Also some typos that prevent compilation when HAVE_POSIX_FALLOCATE is defined. (check-in: bc6cce81 user: dan tags: trunk)
05:06
In-progress changes - do not use; Removed prefix support; Added file control interface to enable/disable and adjust chunk size; added app-def function for same; (check-in: bc02d0c1 user: shaneh tags: multiplex-enhancements)
01:47
Fix the documentation for the sqlite3_column_*_name() functions to describe that the information can be invalidated when a prepared statement is reprepared by the first invocation of an sqlite3_step() for a particular execution cycle. (check-in: 7270f80a user: drh tags: trunk)

03:49
Skip some tests in capi3e.test when compiled with SQLITE_OMIT_UTF16. (check-in: b04304b9 user: shaneh tags: trunk)
2011-02-12
14:23
Fix the expected output on tests so that it corresponds to the new query planner results. All of veryquick.test is now passing with SQLITE_ENABLE_STAT2. (check-in: f2a8b5cc user: drh tags: branch-3.7.2)
05:34
Fix problems in the backport, reducing the number of errors in the TCL tests to just a few dozen. Most of the remaining errors seem to be real and desirable changes of behavior. (check-in: 9d2b0af2 user: drh tags: branch-3.7.2)
01:59
This is the beginning of an attempt to backport recent query planner enhancements to version 3.7.2. The code in this version builds and runs and seems to give correct answers, but it generates suboptimal query plans and hence many of the test cases fail. The test script gives up after 1000 errors.

03:04
Use macros to define the relative costs of search and seek operations when computing costs in the query planner. Current constants seems wrong and need to be fixed, but doing so will alter test results. Need more experimentation to determine accurate relative costs. (check-in: 5f2ec44b user: drh tags: trunk)

05:47
If a deferred foreign key constraint fails on a statement that is not part of a larger transation, make sure that the statement fully ends so that subsequent invocations of the same statement will not pass the constraint because they think the transaction is not closed. This is a merge of the deferred-fk-quirk branch together with a test case. (check-in: 2f94d462 user: drh tags: trunk)

16:00
Ensure that if a deferred FK constraint is violated by a statement that creates its own implicit transaction, the statement is not an "active-write" after sqlite3_step() returns. (Closed-Leaf check-in: 8063197e user: dan tags: deferred-fk-quirk)
15:11
Change the cost estimator in the query planner to take into account the logN rowid lookup cost when going from an index to a table. (check-in: b442525b user: drh tags: stat2-enhancement)

17:03
Do not use mutexes in the pcache implementation unless SQLITE_ENABLE_MEMORY_MANAGMENT is defined. This is a performance enhancement. A side effect is that pcaches will not steal pages from one another unless ENABLE_MEMORY_MANAGEMENT is set, or unless SQLITE_THREADSAFE=0. (check-in: e5ca59e6 user: drh tags: trunk)
16:13
Get all test cases working with the mutex-free-pcache implementation. (Closed-Leaf check-in: 2dc98d29 user: drh tags: mutex-free-pcache)

2011-01-17
21:32
Here is a completely new implementation of the mutex-free-pcache. This one uses a common code base and automatically selects whether or not to use mutexes depending on compile-time and start-time options. (check-in: d094a1bf user: drh tags: mutex-free-pcache)

Fix a typo in the documentation for sqlite3_stmt_readonly(). (check-in: 56417a33 user: drh tags: trunk)
17:42
Add the SQLITE_OMIT_AUTORESET compile-time option which if enabled causes the sqlite3_step() routine to return SQLITE_MISUSE if it is called after it has previously returned anything other than SQLITE_ROW, SQLITE_BUSY, or SQLITE_LOCKED. (check-in: 053ce76d user: drh tags: trunk)
02:24

17:56
Do not raise an SQLITE_CORRUPT error in Recoverymode if the database size in the header is larger than the physical file size. This facilitates recovery of a database in which the database size field has been corrupted. (check-in: 114640d9 user: drh tags: trunk)

01:42
A proposed change to the sqlite3_step() API such that it will only auto-reset following an SQLITE_BUSY or SQLITE_LOCKED error. Calls after any other result other than SQLITE_ROW will return SQLITE_MISUSE. (Closed-Leaf check-in: d1b3c54f user: drh tags: step-autoreset)

Fix the ANALYZE command so that it takes collating sequences into account when gathering index statistics. (check-in: a5867cfc user: drh tags: trunk)
17:57
The ANALYZE command now counts at all rows of an index, even those containing NULL values. A valid sqlite_stat1 entry is created even if the index contains nothing but NULLs. (check-in: 824c8dd3 user: drh tags: trunk)

2010-07-05
21:00
Modify the VFS xAccess() method on winNT so that it returns false for an exists test of a zero-length file. This makes the windows VFS work the same as the unix VFS. (check-in: ec35f254 user: drh tags: trunk)
19:13
Simplify the previous commit by removing the pagerCheckForOrDeleteWAL() wrapper. (check-in: a1324d12 user: dan tags: trunk)
19:03
Allocate a buffer containing the full path-name to the associated WAL file when a pager is created. This saves having to construct a new buffer each time a new read-transaction is opened and SQLite checks for the existance of a WAL file. (check-in: 3053a4ad user: dan tags: trunk)
17:43
When rolling back page 1 from a journal, restore the "nReserve" setting in case it has been corrupted by a prior crash. (check-in: c0d124da user: drh tags: trunk)
14:54

12:54
Call Tcl_ExitThread() from within threads created using Tcl_CreateThread(). Not doing so causes notifier related errors on OSX. (check-in: 684eae66 user: dan tags: trunk)
05:54
Add any files specified as part of the QUICKTEST_INCLUDE environment variable to the set of test files run as part of "make test". Release testing uses this trick. (check-in: a40a6e7d user: dan tags: trunk)

2010-07-01
19:45
If you delete a database file but not its *-wal file, then open the database (thus creating a new empty database file) the *-wal file is automatically deleted. (check-in: 95c69dfb user: drh tags: trunk)

11:06
Remove debugging code from test script. (check-in: a85ae332 user: dan tags: trunk)
10:15
Currently, if SQLite cannot find a table or index referred to by a query, it reloads the database schema from disk to see if the table or index has been added since the schema was cached in memory. Extend this behaviour to columns (which may have been added using ALTER TABLE) and fix some obscure cases related to tables and indexes (INDEXED BY, DROP TABLE etc.). (check-in: 4932f228 user: dan tags: trunk)

Reduce the average (but not maximum) size of the allocations made as part of a checkpoint. (check-in: 4a7fd91b user: dan tags: trunk)
15:16
Reduce the size of the large allocation (approx 8KB for every 4000 frames in the log) that occurs during checkpoint. Use the 'scratch' memory for this allocation instead of the general purpose allocation. (check-in: 29887487 user: dan tags: trunk)
14:17

Merge trunk change [7c3a86b9c7]. (check-in: bd7bc4e0 user: dan tags: experimental)
16:44
A different fix to [fc62af4523]. When changing from journal_mode=PERSIST or TRINCATE to some other rollback mode, delete the journal file only if a RESERVED lock can be obtained on the database file first. (check-in: b9b11855 user: dan tags: experimental)
16:08

02:13
Bug fix: Only trust the database size number at offset 28 if the change counter at offset 24 matches the version number counter at offset 92. This prevents corruption in the case of two applications writing to the database where one is an older version of SQLite and the other is a newer version. (check-in: f80c3f92 user: drh tags: trunk)
2010-06-16
19:04
Experimental change: On systems where it is not possible to unlink a file while one or more processes has it open (i.e. not unix), avoid closing the journal file each time the database is unlocked and reopening it at the start of each transaction. (check-in: bede8c8a user: dan tags: experimental)
