2024-08-29
17:18
Fix a case where the BTCF_AtLast flag was being left set incorrectly. This was causing obscure window function queries to fail. (check-in: 45778b0b user: drh tags: branch-3.46)
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)

2024-08-24
17:37
Avoid a stack overflow that could be caused by a recursively defined WINDOW() with a strategically embedded error. (check-in: 07400271 user: drh tags: branch-3.46)
2024-08-20
14:16
When the database encoding is UTF-16LE and the GLOB optimization is used, it is ok to use the range search over an index, but it is not ok to disable the actual GLOB function call. (check-in: db917d50 user: drh tags: branch-3.46)
12:15
The LIKE/GLOB optimization restricts its attention to the pattern prefix that is all ASCII. (check-in: 5815f132 user: drh tags: branch-3.46)

18:59
Update the fts5_tokenizer_v2 API so that the locale is passed as parameter to xTokenize(), instead of via a separate call to xSetLocale(). (check-in: 03e63ed2 user: dan tags: fts5-locale)
16:29
Revision to check-in d9f726ade6b258f8 so that OOM and other unrelated failures are not overridden by a syntax error in the tokenizer spec. (check-in: fc956353 user: drh tags: branch-3.46)
14:56
Fix behavior change in the offset() SQL function introduced by check-in f0b671183f44d0ae. (check-in: d6fc6e5f user: drh tags: branch-3.46)

Cherrypick various minor fixes from trunk into branch-3.46. (check-in: 6047b18e user: drh tags: branch-3.46)
10:14
Enhancements to covering-index prediction. Add early detection of over-prediction of covering-indexes so that sqlite3_prepare() will return an error rather than just generate bad bytecode. (check-in: 4afe3201 user: drh tags: branch-3.46)
2024-08-09
20:59
Ensure tokenizers registered with xCreateTokenizer_v2() can be accessed using xFindTokenizer(), and that those registered with xCreateTokenizer() work with xFindTokenizer_v2(). (check-in: a3ef7d47 user: dan tags: fts5-locale)
12:20
Remove unused static var cBadGroup from ext/consio/console_io.c to resolve a compiler warning reported in the fossil forum. This is a build fix, not a functional change. (check-in: be3de2e6 user: stephan tags: branch-3.46)
10:56
Fix some signed/unsigned compiler warnings on this branch. (check-in: 681d2280 user: dan tags: wal2)

Ensure sqlite3expert.c unregisters any SQL user-functions it registers with the database handle before returning. (check-in: 27083144 user: dan tags: branch-3.46)
14:49
Do not let the number of terms on a VALUES clause be limited by SQLITE_LIMIT_COMPOUND_SELECT, even if the VALUES clause contains elements that appear to be variables due to the use of double-quoted string literals. (check-in: 05dbfad7 user: drh tags: branch-3.46)
14:45
Do not let the number of terms on a VALUES clause be limited by SQLITE_LIMIT_COMPOUND_SELECT, even if the VALUES clause contains elements that appear to be variables due to the use of double-quoted string literals. Chromium issue 358174302. (check-in: 670beb13 user: drh tags: trunk)
12:14
Back out the --memory option to ".parameter init" in the CLI, as the capability is no longer needed for testing due to the new "$int_N" and "$text_T" automatic bindings, and the "init --memory" is hence just added complication. (check-in: 3b1b0c14 user: drh tags: trunk)
12:08
In the CLI, recognize magic parameter names "$int_NNN" and "$text_TTT" and bind them with integer value NNN and text value TTT respectively. Intended for testing and debugging use only. (check-in: a929cdb0 user: drh tags: trunk)
10:55
Move a misplaced va_end, as reported in forum post 702c79e9da. (check-in: 569824c7 user: stephan tags: branch-3.46)
10:51
Move a misplaced va_end, as reported in forum post 702c79e9da. (check-in: daa25fb3 user: stephan tags: trunk)
10:10
Add the --memory option to the ".parameter init" CLI command. When present, the --memory option causes the sqlite_parameters table to be created in a completely independent :memory: database. This can be done to avoid parameter binding queries from being affected by debug settings such as ".wheretrace", ".treetrace", "PRAGMA vdbe_addoptrace=on", and similar. (check-in: 4e69dce2 user: drh tags: trunk)
2024-08-07

2024-08-06
23:09
Remove unused test cases from FTS5, as they interfere with "grep". (check-in: 048a71ba user: drh tags: trunk)
22:54
Improved robustness of parsing of tokenize= arguments in FTS5. (check-in: 7a65ac42 user: drh tags: branch-3.46)
22:49
Improved robustness of parsing of tokenize= arguments in FTS5. Forum post 171bcc2bcd. (check-in: d9f726ad user: drh tags: trunk)
20:00
Improvements to ./configure that will hopefully break fewer builds. (check-in: 769e32a6 user: drh tags: trunk)
10:29
Change the AggInfoColumnReg() and AggInfoFuncReg() macros for compilers that cannot parse empty elements of a comma expression. Forum post 8fd21998dc. (check-in: 533a6251 user: drh tags: trunk)
2024-08-04
10:13
Restore legacy "tcl_install" makefile target, as an interim measure until I can figure out what is going on. (check-in: 931ad7d9 user: drh tags: trunk)
2024-08-03
23:00
Fix to the previous checkin: The colUsed parameter should have high-order bit set if any of the 64-th or greater columns of the virtual table is used. The lower 63 bits of colUsed always show the usage of the first 63 columns of the virtual table. (check-in: 90ac8457 user: drh tags: trunk)
21:45
Ensure that the sqlite3_index_info.colUsed mask always includes the PK fields of WITHOUT ROWID virtual tables. (check-in: ff4ac279 user: drh tags: trunk)
18:58
Fix a typo in [c327c0c0] preventing the shell tool from running ".dump" scripts that feature virtual tables. (check-in: 10e97abb user: dan tags: trunk)
18:45
Ensure the sqlite3_index_info.colUsed mask always includes the PK fields of WITHOUT ROWID vtabs in cases where they may be used. (Closed-Leaf check-in: c327c0c0 user: dan tags: vtab-pk-colUsed-fix)
15:55
Add the --status option to the test runs using testrunner.tcl. Only works on Unix platforms. The "exec" command appears to interfere with VT100 escape codes on windows. (check-in: 94015cda user: drh tags: trunk)
2024-08-02
21:06
Change things so that locale=1 is required to write fts5_locale() values to an fts5 table, and so that blobs may not be stored in indexed (i.e. not UNINDEXED) columns of these tables. (check-in: c98ccc12 user: dan tags: fts5-locale)
18:20
Make sure the input buffer is big enough for an memcpy() when doing the restore autodetection in the shell. (check-in: 1637d29d user: drh tags: trunk)
17:36
Add the "-d SECS" option to the "status" command of testrunner.tcl (check-in: 2151ea31 user: drh tags: trunk)
15:28

00:56
Previous Makefile.in change broke the tclextension-install target. (Closed-Leaf check-in: 7748367c user: drh tags: autoconf-revamp)
00:51
Continuing refinements of the tclextension-install makefile target. (check-in: 871c20a8 user: drh tags: autoconf-revamp)
00:19
Extra robustness for the SQLite Tcl Extension builder, so that it works on Debian Linux. (check-in: 2f0738da user: drh tags: autoconf-revamp)
2024-08-01
23:30
Simplification the ./configure script. Carry Makefile CFLAGS and OPTS through into builttclext.tcl. Fix a bug in tclsqlite.c introduced by the previous check-in. (check-in: 72a80aa0 user: drh tags: autoconf-revamp)
23:00
Add the tclextension-list makefile target. The the makefile running on Mac. (check-in: 2f667cc8 user: drh tags: autoconf-revamp)

New makefile targets: tclextension-install and tclextension-uninstall. Seem to work on Linux. (check-in: 534f8344 user: drh tags: autoconf-revamp)
20:18
Work on a TCL script that will compile and install the TCL extension. Works on Linux only, so far. This is an incremental check-in. (check-in: 58babd2a user: drh tags: autoconf-revamp)
18:10
Clean up and restructure the TCL configuration sections in autoconf. The new --with-tclsh=FILE option lets you select the specific tclsh that you want to run. (check-in: 8fafc679 user: drh tags: autoconf-revamp)
17:15
Clarify the role of Fts5Storage.pSavedRow in the new feature on this branch. (check-in: e8a61d5c user: dan tags: fts5-locale)
14:43
Include a test case summary in the output of "errors" in testrunner.tcl. (check-in: 173df147 user: drh tags: trunk)
14:16
Add the "errors" command to testrunner.tcl. (check-in: 03b7f992 user: drh tags: trunk)
01:06
Merge the latest trunk enhancements into the reuse-schema branch. (check-in: ff9fdd07 user: drh tags: reuse-schema)

Merge the latest trunk enhancements into the lateral-join branch. (check-in: ac6ae846 user: drh tags: lateral-join)
23:46
Merge all the latest trunk enhancements into the exists-to-join branch. (Leaf check-in: 9084a4c8 user: drh tags: exists-to-join)
22:36
Fix the tclsqlite.c TCL interface module so that it works with both Tcl8 and Tcl9. Make changes across the TCL-based test harness to enable SQLite to be tested with either Tcl8 or Tcl9. Get the --with-tcl= argument on the configure script working. Testing changes only - no changes to the SQLite core. I believe the previous merge attempt didn't work because of errors in the merge itself, not because of faults in the code. Trying again... (check-in: ea9d88f9 user: drh tags: trunk)
22:26
testrunner.db should be in WAL mode for improved concurrency while running "watch sqlite3 test/testrunner.tcl status". (Leaf check-in: f23ad097 user: drh tags: tcl9)
22:25
Make the #include section of tclsqlite.c the same as tclsqlite.h. (check-in: 2afadbeb user: drh tags: tcl9)
22:17
Fix typo in testrunner.tcl for the "status" command that was causing it to fail if any errors were seen. (check-in: 8327c5ed user: drh tags: tcl9)
21:59
Use `<tcl.h>` instead of `"tcl.h"` to include the TCL interface. (check-in: 4e32d4ae user: drh tags: tcl9)
21:46
Changed: Move this back onto the branch. It isn't ready for trunk yet. Fix the tclsqlite.c TCL interface module so that it works with both Tcl8 and Tcl9. Make changes across the TCL-based test harness to enable SQLite to be tested with either Tcl8 or Tcl9. Get the --with-tcl= argument on the configure script working. Testing changes only - no changes to the SQLite core. (check-in: 2a04b1be user: drh tags: tcl9)
20:49
Fix various problems with the code on this branch. (check-in: 8bd4ae7e user: dan tags: fts5-locale)
19:57
More tweaks to testfixture-implemented TCL commands to make them safe for Tcl9. (check-in: 67897ca9 user: drh tags: tcl9)
19:56
Under Tcl9, the %x format letter truncates to 32-bits. Must use %llx in order to get a 64-bit rendering. (check-in: a3044e0a user: drh tags: tcl9)
17:15
Fixes to testfixture routines needed to test snapshots. (check-in: 66f61c3b user: drh tags: tcl9)
16:37
Fix a typo in testrunner_data.tcl that prevented --with-tcl specifications from being carried through into sub-builds. Adjust test cases to account for new floating-point differences discovered when --with-tcl was fixed. (check-in: b8f81351 user: drh tags: tcl9)
15:46
Add missing documentation for new features to fts5.h. (check-in: fa0da3b2 user: dan tags: fts5-locale)

11:42
Adjust the configure script so that the --with-tcl option is used to find the appropriate tclsh. (check-in: 6fb9e37c user: drh tags: tcl9)
11:12
Patch to testrunner.tcl so that it works with Tcl9's pedantic UTF-8 checking. (check-in: 8d4a23d3 user: drh tags: tcl9)
10:59
Fixes to tclsqlite.c to facilitate TEA installs. (check-in: 7157c3c9 user: drh tags: tcl9)
10:52
Merge latest changes from trunk into this branch. (check-in: ff64939e user: dan tags: fts5-locale)
02:01
Fix a problem with strictly conforming UTF8 in shell1.test. (check-in: 8ee187f9 user: drh tags: tcl9)
01:53
Adjust a few tests that don't work even with the new floating point comparison routine. (check-in: 895125a4 user: drh tags: tcl9)
01:45
Implement a new comparison routine to compare text renderings of floating point values. This gets the number of failures down to just 5. But the routine needs work, and probably refactoring. (check-in: 71f2ee5d user: drh tags: tcl9)
2024-07-30
20:39
Fix cases surrounding blob values being stored in locale=1 fts5 tables. (check-in: ae435aff user: dan tags: fts5-locale)
20:39
All tests in "make test" now pass with Tcl9, except for about 198 cases where the error involves small differences in the rendering to floating point values. (check-in: 8e27f532 user: drh tags: tcl9)
18:49
More adjustments to the incrblob channel: Apparently you need to wait until the close2Proc is called with a flag of 0 before actually shutting down the channel. (check-in: fa549a55 user: drh tags: tcl9)
18:42
Adjustments to test cases for session so that they work with Tcl9. (check-in: d417415b user: drh tags: tcl9)
18:15
Tcl_ChannelType implementations for Tcl9 apparently require that wideSeekProc be implemented. Also adjust minor test script issues for fts5 tests so that they can be run sequentially and so that they do not depend on the specific floating point output formats generated by Tcl. (check-in: 19fda979 user: drh tags: tcl9)
17:09
Get rid of "-encoding binary" across all test cases, as that is no longer supported in Tcl9. Use "-translation binary" instead. (check-in: e0d9670d user: drh tags: tcl9)
16:59
Use the SQLite format() function to format floating point values for test results, to avoid inconsistences in TCL versions. (check-in: 6a63c472 user: drh tags: tcl9)
16:51
Fix the incrblob channel so that partial close works with Tcl9. (check-in: d54ec2de user: drh tags: tcl9)
15:55
Update the highlight() and snippet() functions to use locales when available. (check-in: 569ae56a user: dan tags: fts5-locale)
15:49
First attempt at getting the build to work with Tcl 9.0. (check-in: 6e5bb48a user: drh tags: tcl9)
2024-07-29
20:31
Fix xColumnText() and xColumnSize() APIs. Add xColumnLocale() and xTokenizeSetLocale(). (check-in: 14006711 user: dan tags: fts5-locale)
17:59
The idea here was to simply an expression like "(a=5) IS TRUE" into "(a=5)=TRUE". But that does not work, since the original form is FALSE if y is NULL whereas the second form is NULL. Patch save for historical reference only. (Closed-Leaf check-in: d029e943 user: drh tags: broken-istrue-opt)
15:00
Fix a couple of asan problems on this branch. (check-in: 4e3e5293 user: dan tags: fts5-locale)
2024-07-27
20:28
Fix documentation typo. Forum post 993cb82402 (check-in: 86de4e75 user: drh tags: trunk)
19:46
Ensure that an fts5 UPDATE does not strip the locale from columns that it does not write to. (check-in: 69205264 user: dan tags: fts5-locale)
2024-07-26
20:50
Add the fts5_locale() function, and begin adding the related functionality to fts5. (check-in: 8839ef7c user: dan tags: fts5-locale)
2024-07-25
16:28
Fix a non-bare-bones-mode test case broken by the previous checkin. (check-in: 3be72949 user: stephan tags: wasm-build-rework)
16:21
Strip progress handlers and window functions from the wasm bare-bones (formerly 'minimal') JS bits, noting that we can't yet use OMIT_WINDOWFUNC (for the C parts) without a custom amalgamation. Currently at 604kb. (check-in: ec02e923 user: stephan tags: wasm-build-rework)
14:00
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. (check-in: b029c406 user: stephan tags: wasm-build-rework)
10:50
Start work on an overhaul of the wasm build process, with an eye towards less over-engineering. (check-in: ed746b3d user: stephan tags: wasm-build-rework)
2024-07-24
23:58
wasm minimal build: strip authorizers and JSON support (saves approx 35kb). Strip vtab support from the JS bits but cannot yet strip it from the C bits because that requires a custom-configured sqlite3.c. (check-in: eb64d106 user: stephan tags: trunk)
22:07
Restructuring of the wasm build to support an experimental 'minimal' build mode which elides all non-core APIs. (check-in: ee2191f7 user: stephan tags: trunk)
13:53

20:58
OPFS VFSes: remove the on-open() pragma calls, as those (A) already reflected the build-time default settings and (B) they made it illegal to run locking_mode=exclusive, which is a requirement for WAL mode without shared memory.

Disable the reuse of IN-clause subqueries if the subquery is an explicit "SELECT ALL".

Assume that an SQL function is able to return a subtype if any of its arguments are SQL functions that are able to return subtypes. This closes a corner-case hole in the patch at [ba789a7804ab96d8]. (check-in: b36d499e user: drh tags: trunk)
15:04
Assume that a function is able to return a subtype if either (1) it is itself marked with SQLITE_RESULT_SUBTYPE, or (2) one of its arguments is a function that is able to return a subtype. This check-in backs out the code changes from the previous two on this same branch, but keeps the test cases from the previous two. (Closed-Leaf check-in: f16b200f user: drh tags: func-rw-subtype)

Fix the CREATE TABLE performance issue described by forum thread 4cf69794d9dfff7c in two different ways: (1) Omit the call to PRAGMA integrity_check('X') that was being done after CREATE TABLE "X" because the result was being ignored and the integrity_check was not doing anything other than burning CPU cycles. (2) Do not interpret the argument to PRAGMA integrity_check as a number if it is in fact a string that looks like a number. (check-in: 71f08b91 user: drh tags: trunk)

11:51
Omit the OP_SqlExec to "PRAGMA integrity_check" added by [348fa7aaf7958b3f] because it is a no-op. Even if the integrity_check failes, the CREATE TABLE is stull successful. The OP_SqlExec just burns CPU cycles for no reason. (check-in: 532795ac user: drh tags: faster-create)

Improvement to the way that affinity is determined for columns of a compound subquery. The affinity is the affinity of the left-most arm of the compound subquery that has an affinity other than NONE, adjusted to accommodate the data types coming out of the other arms. (check-in: e6df846f user: drh tags: trunk)
17:52
Further improvements to the computation of affinity for compound subqueries: make sure that the selected affinity is compatible with a literal values in arms to the left of the arm that is used to determine affinity. (Closed-Leaf check-in: bbdf22e3 user: drh tags: compound-subquery-affinity)
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)

If a RETURNING clause contains a subquery that references the table that is being updated in the statement that includes the RETURNING clause, then mark the subquery as correlated so that it is recomputed for each result and not just computed once and reused.

Extend the JS/WASM SEE build support by (A) filtering SEE-related bits out of the JS when not building with SEE and (B) accepting an optional key/textkey/hexkey option to the sqlite3.oo1.DB and subclass constructors to create/open SEE-encrypted databases with. Demonstrate SEE in the test app using the kvvfs. This obviates the changes made in [5c505ee8a7]. (check-in: 8fbda563 user: stephan tags: trunk)

Extra robustness in the code that causes cursors to return NULL when they are participating in an OUTER JOIN. (check-in: 672c2869 user: drh tags: trunk)
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. (check-in: 5c505ee8 user: stephan tags: trunk)
00:42
Continuation of the fix at [8c0f69e0e4ae0a44]: If a viaCoroutine FROM clause term is participating in a RIGHT or FULL JOIN, we have to create an always-NULL pseudo-cursor for that term when processing the RIGHT join. dbsqlfuzz 6fd1ff3a64bef4a6c092e8d757548e95698b0df5.
