Combine the implementations of the ".tables" and ".indexes" commands in the command-line shell. The ".indexes" command now puts the indexes in multiple columns, just like ".tables" and shows all indexes in all attached databases. (check-in: def29333 user: drh tags: trunk)
19:37
The schema name "main" is always an acceptable alias for the primary database even if the primary database is renamed using SQLITE_DBCONFIG_MAINDBNAME. (check-in: 2f481b85 user: drh tags: trunk)
18:18
Change the output format of the ".databases" command in the command-line shell so that it shows the schema name, a colon, and the corresponding filename. (check-in: 8558512e user: drh tags: trunk)

19:45
Simplifications to the way UnpackedRecord objects are allocated. Smaller and faster code that also fixes a subtle (currently unreachable) bug. (check-in: f7ab01f2 user: drh tags: trunk)
2016-12-18
17:42
Change the OP_IfNotZero opcode so that it decrements register P1 by 1 rather than the value in P3, and so that it only decrements if originally positive. This avoids decrementing the smallest 64-bit signed integer. (check-in: 165c0446 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)

Further changes to the date/time functions to suppress harmless signed integer overflow warnings that could have occurred when doing out-of-range date calculations which, according to the docs, give undefined results. (check-in: dc453b34 user: drh tags: trunk)
2016-11-29
20:39
The documentation says that the built-in date-time functions give undefined results for dates before 0000-01-01 and after 9999-12-31. Change the actually implementation so that the answer given is really NULL.

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.

Reinstate the mechanism in BETWEEN that avoids evaluating the first expression more than once, but fix the affinity extractor so that it works with this mechanism.

The docs promise the in "x BETWEEN y AND z" the x expression is only evaluated once. That is no longer true, and so some tests are failing. This needs to be fixed before merging to trunk. (check-in: e50d264f user: drh tags: rowvalue)

00:07
Change the way TK_SELECT_COLUMN is handled so that the subquery is only generated once even if part of the vector comparison is used for indexing and the other part is now. This change also is a pathway to vector assignment in UPDATE statements. (check-in: d8feea7d user: drh tags: rowvalue)

14:20
Add the capability to VACUUM an attached database by specifying the schema name as an argument to the VACUUM command. Since version 2.0, VACUUM has accepted an argument which was silently ignored. Now it has meaning. (check-in: 29d63059 user: drh tags: vacuum-attached-db)

16:20
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.

14:11
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

22:13
In a query with both ORDER BY and LIMIT, if the inner loop satisfies the ORDER BY then try to cut short each invocation of the inner loop once the LIMIT has been satisfied. This check-in is a partial implementation only. (check-in: 852d1eda 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.

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. This ensures that if an RBU vacuum operation either completes successfully or encounters an error, the next call to sqlite3rbu_vacuum() with the same parameters starts a new RBU vacuum operation.

Updates to ensure the values of PRAGMA settings like "page_size", "auto_vacuum", "user_version" and "application_id" are not lost when a database is RBU vacuumed. (check-in: 74ffea76 user: dan tags: rbu-vacuum)
17:11
When an RBU vacuum is started on a db identified using a URI filename, pass the same URI parameters when creating the new version of the db. This ensures that RBU vacuum works with password protected databases. (check-in: ca021ba8 user: dan tags: rbu-vacuum)

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. Consider this check-in a proof-of-concept. It needs improvement before going on trunk. Some tests fail, but only because they new use fewer key comparisons than expected (which is a good thing!).

13:27
Disable the read-only WAL-mode database tests on the apple-osx branch because read-only WAL-mode databases are specifically disallowed by Apple-specific changes. (check-in: bd911496 user: drh tags: apple-osx)
09:27
Merge latest trunk changes with this branch. (check-in: 57bc0194 user: dan tags: begin-concurrent)

03:33
Enhance the json_insert(), json_replace(), and json_set() functions with the ability to add JSON instead of text if the argument is text and if the PATH begins with '$$' instead of just '$'. (check-in: 44f103d8 user: drh tags: trunk)

Add miscellaneous test cases for concurrent transactions. (check-in: 779b1d0e user: dan tags: begin-concurrent)
17:16
If "PRAGMA integrity_check" is run while the database is being written by a CONCURRENT transaction, do not consider unreferenced pages to be an error. They may be part of the free-page list, which is not visible at the b-tree layer when running a CONCURRENT transaction. (check-in: f32b57b4 user: dan tags: begin-concurrent)
16:57
Add code to maintain indexes with expression arguments across DELETE, INSERT, and UPDATE statements. Legacy tests pass, but the new code paths are still largely untested. The query planner currently makes no effort to use expression indexes. (check-in: efaabdb7 user: drh tags: index-expr)
16:01
Test that if a corrupt wal-index header is encountered when attempting to commit a concurrent transaction, SQLITE_BUSY_SNAPSHOT is returned to the caller. (check-in: c746e0bd user: dan tags: begin-concurrent)

22:06
Remove duplicated line of code. (check-in: 47280f2a user: mistachkin tags: begin-concurrent)

20:21
Enhances the parser so that it accepts arbitrary expressions for the arguments of an index, though the code generator still rejects everything other than simple column names. The sqlite3RestrictColumnListSyntax() routine is removed since that feature is now handled by the parser. (check-in: bed42116 user: drh tags: trunk)

Add a specially formatted comment to shell.c to make it easier for scripts to edit. No code changes. (check-in: 6d47b35a user: dan tags: trunk)
09:42
Within a write-transaction on a wal database in mmap mode, check the page-cache for an entry before the wal file. This can be faster if the wal file is very large. (Leaf check-in: 3a82c8e6 user: dan tags: mmap-wal-bigtrans)

Improve the usage comment on sqlite3_analyzer: show the available switches. (check-in: 783f78e3 user: drh tags: trunk)
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)

14:10
The "PRAGMA cache_size" reads the database schema, as it has done in all prior versions of SQLite. This side-effect of cache_size is undocumented, but apparently it does get used and its absence from 3.8.11 was causing problems. (check-in: 4489722a user: drh tags: branch-3.8.11)

17:26
New makefile target "fastfuzztest" runs the same tests as "fuzztest" but with a 100M memory size limit. This more than doubles the speed. The original unlimited "fuzztest" is still run on a "fulltest". (check-in: cfeb1b1c user: drh tags: trunk)

"test" targets on all makefiles use --verbose=file --output=test-out.txt. Add the new "quicktest" target to all makefiles - designed to run in under three minutes. The --quick option on releasetest.tcl now uses quicktest. (check-in: 6ddef2ad user: drh tags: trunk)
17:20
Resolve FROM-clause subqueries after query planning instead of before. Greatly reduce the estimated cost of automatic indexes for VIEWs and ephemeral tables since performance problems there cannot be mitigated via a CREATE INDEX. (check-in: a1eaf171 user: drh tags: view-optimization)

2015-06-08
22:59
Code refactoring to try to shift FROM-clause subquery manifesting until after the query planner runs.

01:35
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. This is a stop-gap means of controlling the decision to manifest while we try to work out a better to make that decision automatically. (check-in: a29e117d user: drh tags: trunk)

Oops - the deephemerialization needs to occur before the move, not after. Was: Rather than try to keep track of the parent of an ephermeral register when the register moves, just deephemeralize all registers touched by the OP_Move opcode. (Closed-Leaf check-in: 091cfe8e user: drh tags: mistake)
12:44
Shift the Mem.pScopyFrom pointer in the correct direction in OP_Move. Fix for a defective check-in [a2135ad13049] and ticket [d6352363751]. Debugging code only - does not affect normal operation. (check-in: add4e043 user: drh tags: trunk)

17:22
Modify the sqlite3session_diff() API so that tables with no PRIMARY KEYs are ignored. This matches the other sessions APIs.

Experimental sqlite_db_config() setting to disable writing to all btrees except for one btree with a particular root page. (check-in: 23054110 user: drh tags: one-writable-btree)
2015-01-28
20:37
Add missing VdbeCoverage() macros to the sqlite3_index_writer() implementation. (check-in: 6f8cda26 user: drh tags: ota-update)
15:30
When a "full", "restart" or "truncate" checkpoint is attempted, return SQLITE_BUSY if a reader prevents the checkpointer from copying any frames at all into the database file. (check-in: f2700040 user: dan tags: ota-update)
12:27
Correctly detect errors returned by walCheckpointStart() due to OOM. (check-in: 8e878c20 user: drh tags: ota-update)

Fix a problem with fts5 doclist-indexes that occured if the first rowid of the first non-term page of a doclist is zero. (check-in: f704bc05 user: dan tags: fts5)
19:01
Fix a bug in the fts3 snippet() function causing it to omit leading separator characters from snippets that begin with the first token in a column. (check-in: adc9283d user: dan tags: trunk)
18:43
Improve the performance of fts3/4 queries that use the OR operator and at least one auxiliary fts function. (check-in: 245e8730 user: dan tags: trunk)
13:17
Fix a (almost always harmless) read past the end of a memory allocation that comes about because the Expr.pTab field is checked on an EXPR_REDUCEDSIZE Expr object before checking the Expr.op field to know that the Expr.pTab field is meaningless. (check-in: e098de69 user: drh tags: trunk)
2015-01-25
20:19
The va_list argument cannot take on a NULL value and cannot be compared with NULL on some platforms (ex: ARM). So do not attempt to do so. (check-in: 1964e656 user: drh tags: trunk)
2015-01-24
19:57
Have fts5 store rowids in ascending order. Query speed is virtually the same regardless of rowid order, and ascending order makes some insert optimizations easier. (check-in: 5206ca60 user: dan tags: fts5)
12:12
In the command-line shell, make sure stderr is unbuffered so that it automatically flushes. This has always been the case already for unix and on Windows when the output is a console, but apparently was not the case on Windows when the output was a pipe. (check-in: 2a9ea9b4 user: drh tags: trunk)
2015-01-23

Add further tests and fixes for fts5. (check-in: 5b295897 user: dan tags: fts5)
12:00
Make sure errors in the FROM clause of a SELECT cause analysis to abort and unwind the stack before those errors have a chance to mischief in the "*" column-name wildcard expander. Fix for ticket [32b63d542433ca67]. (check-in: 9e6eae66 user: drh tags: trunk)

2015-01-19
21:38
Ensure that the KeyInfo.nXField value for ephemeral tables used to implement ORDER BY or GROUP BY clauses is set correctly, so that the sqlite3VdbeFindCompare() routine can choose the correct comparison function. Add assert() statements to the high-speed comparison functions to detect cases where they are inappropriately chosen. Fix for ticket [f97c4637102a3ae72b7911]. (check-in: 59e592f6 user: drh tags: branch-3.8.8)
21:36
Ensure that the KeyInfo.nXField value for ephemeral tables used to implement ORDER BY or GROUP BY clauses is set correctly, so that the sqlite3VdbeFindCompare() routine can choose the correct comparison function.

Improve precision of the new test case by removing a superfluous carriage-return from the shell command input. (check-in: 913c41b2 user: mistachkin tags: expShell)
21:11
Add comments and improve the new test case. (check-in: 4ec2aead user: mistachkin tags: expShell)
21:10
There are asserts in place now that will prevent a recurrence of ticket [f97c4637102a3ae7]. Nevertheless, it is good to add some test cases as well. (Closed-Leaf check-in: e02959b9 user: drh tags: tkt-f97c4637)
20:59
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)

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)

Makefile enhancements: (1) Rename autoconf/tea/configure.in to autoconf/tea/configure.ac so that it works with the latest versions of autoconf. (2) Add the "amalgamation-tarball" targets to Makefile.in and main.mk (renamed from "dist" in the latter case). (3) Update the README.first file in autoconf/ (4) The TOP macro in Makefile.in is now an absolute rather than a relative path. (check-in: 3bafeec9 user: drh tags: trunk)

21:26
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)
15:21
Add the ability to put comments in the Config and Platform setup sections of the releasetest.tcl script. (check-in: d6f8c899 user: drh tags: trunk)

02:15
In releasetest.tcl: (1) Add the Failure-Detection platform. (2) Re-add the --disable-shared argument on Default that was mistakenly removed by the previous commit. (3) Remove the -ftrapv tests, as we read that -ftrapv does not work in GCC. (check-in: 1f2fb777 user: drh tags: trunk)
01:05
In releasetest.tcl: add options --veryquick and pass-through compiler optimization settings (ex: -O0). Collect the SQLite version number from the main.test output and show it during the summary report at the end. (check-in: e7e7bc1d user: drh tags: trunk)
2015-01-07
19:38
In releasetest.tcl, always use --disable-shared together with --disable-amalgamation because mingw generates a binary that crashes and cannot be debugged using gdb if you don't. (check-in: 19982439 user: drh tags: trunk)

In releasetest.tcl, change the --dryrun option to work as it does in multitest.tcl of TH3. Add the new --trace option that work like the --dryrun option used to work. Add the ability to specify additional configure-script options in the Config array, and create configurations that use --disable-shared and --disable-amalgamation for testing. (check-in: be17ef03 user: drh tags: trunk)

20:41
Tests and fixes for fts5 external content tables. (check-in: 047aaf83 user: dan tags: fts5)
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)
19:16
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)
15:48
Remove some needless recursion from compound SELECT processing. (check-in: fe677d13 user: drh tags: trunk)

Add logic to releasetest.tcl that detects -fsanitize=undefined errors. Fix a few false-positivies that come up when running the sanitize=undefined test. (check-in: 2835e79a user: drh tags: trunk)
19:53
Add the ability to specify an alternative compiler (clang instead of gcc) on the default Makefile. Use this in releasetest.tcl to implement an -fsanitize=undefined test. (check-in: c55c05fe user: drh tags: trunk)
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)
18:54
Fix an error in the computation of the number of hours of runtime for individual test runs in the releasetest.tcl script. (check-in: e2b0ebe2 user: drh tags: trunk)

00:20
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. We might later add the keyinfo cache back but only enable it when shared-cache mode is off. (check-in: b7489f94 user: drh tags: threadtest4)

Fix the sqlite3_table_column_metadata() routine so that it gives the correct answer for the "rowid" column in a WITHOUT ROWID table.

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)

Remove an unnecessary branch from balance_nonroot(). (check-in: 9fc7c88e user: drh tags: trunk)
00:05
In the balance_nonroot() routine, protect the values in aPgno[] array from change during the page sort, so that aPgno[] can be used to avoid unnecessary pointer-map updates for auto_vacuum databases. (check-in: 69c3924f user: drh tags: trunk)
2014-10-30
23:14

11:25
Add test file e_wal.test. (check-in: fc6920b5 user: dan tags: trunk)
08:02
If a free-slot is found within a page, but using that free-slot would fragment the page further and there are already at least 60 fragmented bytes, degragment the page. This matches the behaviour of the trunk. (Closed-Leaf check-in: 1f80f8c1 user: dan tags: defrag-opt)
07:01
Merge trunk with this branch. (check-in: a13df301 user: dan tags: defrag-opt)

01:01
Implement sqlite3_create_collation() by invoking sqlite3_create_collation_v2() with a NULL destructor argument. This saves a little space. (check-in: 9762ad06 user: drh tags: trunk)
2014-10-22
20:07
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)
18:42
Merge latest trunk with this branch. (check-in: 854a54c6 user: dan tags: defrag-opt)
16:25
The _beginthreadex() / _endthreadex() functions should only be used when compiling with MSVC. (Closed-Leaf check-in: 1a5a5da3 user: mistachkin tags: msvcThreads)

16:01
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)

11:31
Rearrange an expression in vdbemem.c to avoid a (harmless) reference to a possibly unitialized variable. (check-in: 4a7b3fa0 user: dan tags: trunk)
2014-10-14
20:25
Make sure new sqlite3_vtab objects created by the xCreate() virtual table method are initialized by the system, in accordance with the documentation. (check-in: eab82330 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)
18:09
Merge trunk changes into this branch. (check-in: d5b7c5a8 user: dan tags: defrag-opt)
18:03
Further work on balance_nonroot(). (check-in: 6594f9b4 user: dan tags: defrag-opt)
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. (check-in: 91384a7d user: drh tags: trunk)
2014-10-11
23:31
Performance optimization and very slight size reduction for OP_Column. (check-in: 869c30e4 user: drh tags: trunk)

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)

Fix a failing test case in index5.test. Also tweak the way cache memory is divided between read-only and dirty pages when using SQLITE_CONFIG_PAGECACHE to reduce IO in some cases. (check-in: 8541dfb3 user: dan tags: trunk)
18:09
Changes to enable compiling using VC6. (check-in: 9ee5686a user: drh tags: trunk)
17:47
When using the -config option to releasetest.tcl, default the testing type to "fulltest" if it is not specified on the command line. (check-in: cf291cbe 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)
15:01
Fix a potential problem in the whereRangeScanEst() routine when STAT4 is active. The problem was introduced by recent enhancements. (check-in: 68e1b4de user: drh tags: trunk)

2014-10-09
19:35
Change the balance_nonroot() routine to reduce the amount of memcpy work that takes place. This is a work in progress. (check-in: 29304499 user: dan tags: defrag-opt)
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)
14:00

Add a test to show that the change on this branch is effective. (Closed-Leaf check-in: fc619be0 user: dan tags: stat4-avgeq)
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)

2014-09-27
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)
19:51
Merge recent trunk changes (performance enhancements) into the sessions branch. (check-in: 497367cb 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
If an SQL function makes a recursive call to do an INSERT into the same database, make sure that the last_insert_rowid() for that INSERT is recorded. (check-in: e93aecc0 user: drh tags: trunk)

04:38
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)
02:05
Have the clearCell() routine return the cell size to the caller, rather than have the caller make a separate call to cellSizePtr(). (check-in: f21d2175 user: drh tags: trunk)
01:23
Shorten all lines of source code in btree.c to at most 80 characters. No logical changes. (check-in: 5dd41cdb user: drh tags: trunk)

22:36
Avoid calling btreeParseCellPtr() from within fillInCell() since most of what btreeParseCellPtr() computes is ignored by fillInCell(). Instead, have fillInCell() compute the values it needs inline. Performance improvement. (check-in: 4147f667 user: drh tags: trunk)
21:25
Simplify the CellInfo structure for a size reduction and performance improvement. (check-in: bf59df66 user: drh tags: trunk)

22:01
Tighten the conditions under which applyNumericAffinity() be called and add assert() statements to prove that it is never called otherwise. (check-in: e996ca32 user: drh tags: trunk)
20:13
Fix the affinity on inserts into the ANALYZE tables. Change the affinity characters to be upper case, to make the P5 parameter of comparison operators easier to read. (check-in: 3f3ca76a user: drh tags: trunk)

00:43
Add the sqlite3VdbeMemClearAndResize() interface to be used in place of sqlite3VdbeMemGrow(). A C++ style comment was left in this check-in by mistake, and so it has been moved into a branch to avoid problems in any future bisects on windows. (check-in: 5b9b8987 user: drh tags: Cplusplus-comment)

14:14
In the sqlite3_context object, keep a pointer to the result value rather than storing the result value in the sqlite3_context object and using memcpy() to move the value back into its register after the function returns.

20:11
Allow CAST expressions and unary "+" operators to be used in the DEFAULT argument of an ALTER TABLE ADD COLUMN and to be understand on the RHS of range constraints interpreted by STAT3/4. This involves a rewrite of the implementation of the CAST operator. (check-in: 91d8a8d0 user: drh tags: trunk)
19:58
Add documentation for tokenizer api to fts5.h. Also add a script to extract extension API docs and format them as html. (check-in: e240d467 user: dan tags: fts5)

2014-08-22
23:33
Another performance tweak: Split the sqlite3BtreeCursorHasMoved() routine into two with the second routine named sqlite3BtreeCursorRestore(). The first now only reports whether or not the cursor has moved and the second tries to restore the cursor. This allows the sqlite3VdbeCursorMoveto() routine to be refactored to avoid stack pointer movements, for a noticable performance gain. (check-in: ce123b5c user: drh tags: trunk)

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)

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

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)

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.

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)

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)

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)

Add experimental "costmult" logic. Only enabled when compiled with -DSQLITE_ENABLE_COSTMULT. (check-in: 729ece40 user: drh tags: trunk)
19:37
Ugh. Consecutive UNIQUE index entries are only distinct if the index is on NOT NULL columns. So the previous version was not quite right. This check-in fixes the problem. (check-in: 30033f96 user: drh tags: faster-analyze)

13:40
Change the hex literal processing so that only the SQL parser understands hex literals. Casting and coercing string literals into numeric values does not understand hexadecimal integers. This preserves backwards compatibility. Also: Throw an error on any hex literal that is too big to fit into 64 bits. (check-in: 6c6f0de5 user: drh tags: hex-literal)

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)

15:33
Correction: The maximum SQLITE_MAX_ATTACHED value to avoid overflowing a signed 8-bit integer is 125, not 127. (check-in: 48e37802 user: drh tags: trunk)

2014-07-21
20:07
Limit the maximum SQLITE_MAX_ATTACHED to 127, since a signed character is sometimes used to store the database index. (check-in: f1c76c7c 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

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.

12:33
Cancel column-cache entries that are involved in a comparison operator since the comparison might have forced an affinity change. Originally proposed as a fix for ticket [a8a0d2996a], but later determined to be incorrect. (Closed-Leaf check-in: 0b95b7a8 user: drh tags: tkt-a8a0d2996a)

Clear the sort-order flags on the KeyInfo object associated with the OP_Compare/OP_Jump of the block-sort logic, in order to make the OP_Jump fully testable. (check-in: 9b2838f2 user: drh tags: trunk)
01:52
Increase the version number to 3.8.5. (check-in: 9760879d user: drh tags: trunk)
00:27
Fix the ORDER BY optimization logic so that it will do a block-sort on a partial DESC ORDER BY. This enhancement uncovered a memory leak in pushUntoSorter() which is also fixed. (check-in: c36f7461 user: drh tags: trunk)
2014-03-21
20:58
Add the ability to use indices for the first few terms of an ORDER BY clause, then sort in batches to handle the later terms. (check-in: fa06a6fe 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)
18:56
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

Make it possible for block-sort to use the OP_SorterOpen sorter in addition to a generic OP_OpenEphemeral. (check-in: 7ce2daaf user: drh tags: orderby-planning)
16:56
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)

23:40
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)
20:33
Enable the b-tree cursor object's overflow page-number cache, which is normally enabled only for incr-blob cursors, for all cursors. (check-in: da591985 user: dan tags: overflow-pgno-cache)

Enhance the test harness for the sessions interface so that it does not use SQLite operations that can encounter an OOM error in places where it is unable to report an OOM error back up to the test script. (check-in: bc0e6610 user: drh tags: sessions)
13:48
Merge the latest 3.8.4 tweaks from trunk. (check-in: 1ed463d9 user: drh tags: sessions)

Merge in various obscure bug fixes and the removal of Mem.memType from trunk. (check-in: 0828975d user: drh tags: sessions)
14:40
When converting a result type from TEXT to BLOB using the sqlite3_value_blob() interface, continue to report SQLITE_TEXT as the true type from sqlite3_value_text() as long as that text is still valid. The maintains legacy behavior from before the noMemType change. (check-in: 1d134ba2 user: drh tags: trunk)

Refactor the sqlite3VdbeRecordCompare() routine used to compare btree records. Create fast-track special case routines to handle the common cases more quickly. This gives a significant performance boost. (check-in: 3325ad5b user: drh tags: trunk)
04:04
Fix more instances of assuming 'char' is signed. And, make sure to never shift a signed integer. (Closed-Leaf check-in: f10130ed user: drh tags: broken-on-arm)

2014-03-03
21:59
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)
21:46
Fix a couple of harmless compiler warnings. (Closed-Leaf check-in: fcf480cc user: drh tags: experimental)

Fix a segfault that can occur following an OOM error. (check-in: 7fdd378d user: dan tags: trunk)
00:12
Change the MEM_Dyn flag so that it means that Mem.xDel exists and must be used to free the string or blob. Add tighter invariant checks on Mem. (check-in: e3f6c61e user: drh tags: trunk)
2014-03-01
19:45

Factor the Mem invariant checker into a separate procedure (rather than a macro) so that it can be more easily extended. (check-in: 354699d5 user: drh tags: enhanced-mem-check)
14:45
Add extra assert() statements trying to catch a Mem object in an inconsistent state. (check-in: 4aeb3ae4 user: drh tags: enhanced-mem-check)
2014-02-28
20:47
In the command-line shell add the (undocumented and unsupported) ".eqp" command and -eqp command-line option, to cause EXPLAIN QUERY PLAN to be run on each SQL statement as it is evaluated. Intended use is for analysis of the query planner. (check-in: e6ecf733 user: drh tags: trunk)

Further changes to sqlite3VdbeRecordCompare(). (check-in: 57089374 user: dan tags: experimental)
15:11
A better way of handling the USE_SYSTEM_SQLITE #define in shell.c. (check-in: 51ce713c user: drh tags: trunk)
15:04
Add #defines to the command-line shell source code (shell.c) so that it can be imported directly into other projects (ex: Fossil) and used without editing. (check-in: a6690400 user: drh tags: trunk)
05:47

2014-02-26
21:35
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. (Leaf check-in: 3ad687b7 user: drh tags: open-only-once)
13:53
In the command-line shell for CSV import, if the lines are \r\n terminated and the last field is blank, make sure an empty string and not a "\r" string is imported. (check-in: 9c2e7612 user: drh tags: trunk)
02:26
Improved handling of constants and especially constant functions in the ORDER BY clause of a query. Do not optimize out "ORDER BY random()". Fix for ticket [65bdeb9739605cc2296]. (check-in: dca1945a user: drh tags: trunk)
2014-02-25
21:55
Do not allow temporary registers to be in use across an OP_Yield within a co-routine. Fix for ticket [8c63ff0eca81a9132d8]. (check-in: 97a8c973 user: drh tags: trunk)
21:01
Attempt to speed up sqlite3VdbeRecordCompare() by various means. This code is in an interim state. (check-in: 85206e0b user: dan tags: experimental)
19:38
Make sure temporary registers used within a co-routine are not also used outside of that co-routine, in order to prevent concurrent use of the same register for two different things. Ticket [8c63ff0eca81a9132d8] (Closed-Leaf check-in: cc5eda54 user: drh tags: tkt-8c63ff0eca)
18:12
Also adjust the order of files in the amalgamation to ensure that _FILE_OFFSET_BITS is defined before any #include, for QNX. (check-in: 23001a85 user: drh tags: trunk)
14:52
QNX requires that _FILE_OFFSET_BITS be set prior to any system #include. (check-in: 953cdd6a user: drh tags: trunk)

Fix several small style/consistency issues with the previous check-in. (check-in: 2477b3a2 user: mistachkin tags: trunk)

Enhance testing support for the Win32 VFS dynamic extension loading facilities. (check-in: 53081e72 user: mistachkin tags: trunk)
19:49
Close some stray connections in walro.test. (check-in: d6746cab user: dan tags: trunk)
19:07
In memsys5, initialize new allocations to non-zero bytes. Change the content of freed allocations to prevent use after free. These changes in SQLITE_DEBUG only. (check-in: ba5f0a55 user: drh tags: trunk)
14:24
Remove an unused variable from the VDBE_PROFILE compile-time option. Keep the opcode count in an u32 instead of an int. (check-in: 4df0ac90 user: drh tags: trunk)
2014-02-21
10:48
Merge updates from trunk. (check-in: 09cf240a user: mistachkin tags: winHdr)

Better loadable extension handling in the Win32 VFS when compiled for Cygwin. (check-in: 6676475c user: mistachkin tags: cygDlOpen)
2014-02-20
19:42
Fix the text of a comment used to generate VDBE opcode documentation so that it omits symbols that can be mistaken for a hyperlink by the parser. (check-in: b46d4e89 user: drh tags: trunk)
19:32
Fix a harmless shadowed-variable warning. (check-in: 82402909 user: drh tags: trunk)

Make sure that the difference between two string pointers is passed into sqlite3_mprintf() as type "int". (check-in: d5d973fe user: drh tags: trunk)
2014-02-19
19:14
Add the VdbeCoverageNeverTaken() macro, and comments that better describe how the VDBE branch coverage measurement works. Add some tags to provide 100% VDBE branch coverage. (check-in: c1e94169 user: drh tags: trunk)
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)
01:31
Make sure a multi-row VALUES clause works correctly in a compound SELECT. (check-in: 85b355cf user: drh tags: trunk)

Enhance the Win32 VFS I/O retry logic. (check-in: adba783c user: mistachkin tags: winIoRetry)
03:07
Add VdbeCoverage() and VdbeCoverageIf() macros for improved VDBE coverage testing. (check-in: b92d31a9 user: drh tags: trunk)
01:07
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. (check-in: 915f6f1c user: drh tags: trunk)
2014-02-17
23:52
Merge in performance enhancements for INSERT operations, especially INSERTs on tables that have no affinity columns or that have many indices or INSERTs with content coming from a SELECT. Add the SQLITE_TESTCTRL_VDBE_COVERAGE test control and the SQLITE_VDBE_COVERAGE compile-time option used for measure coverage of branches in VDBE programs. (check-in: a7268769 user: drh tags: trunk)
22:40
Add logic to do test coverage measurements on the VDBE code. (Closed-Leaf check-in: ce184c7b user: drh tags: insert-optimization)

Merge the VDBE_PROFILE fixes from trunk. (check-in: 2914e419 user: drh tags: insert-optimization)
14:59
Avoid unnecessary calls to applyAffinity() during INSERT and UPDATE operations, especially for table that have indices and tables for which all columns have affinity "NONE". (check-in: 35b4d6e9 user: drh tags: insert-optimization)
01:13
Fix the VDBE_PROFILE logic. Add a script to process the output file. (check-in: 7adb3da2 user: drh tags: trunk)
2014-02-16
19:20
Use the modern MinGW major version macro, not the deprecated one. (Closed-Leaf check-in: 057c16ee user: mistachkin tags: mingw4x)
01:55
Enhance the code generator for INSERT INTO ... SELECT so that the SELECT generates output directly in the registers that INSERT INTO will be using, in many cases, and OP_SCopy operations can thus be avoided. (check-in: aa2d8b0e user: drh tags: insert-optimization)
2014-02-14

Better support for MinGW 4.x. (check-in: e1472307 user: mistachkin tags: mingw4x)
20:59
Reduce the number of cases where it is necessary to check for NULL after the loop terminating condition. (check-in: 3c1ae447 user: drh tags: trunk)
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. (check-in: b6bea903 user: drh tags: trunk)
00:25
Revise how the Tcl system encoding is handled by the test suite. (check-in: 9e573198 user: mistachkin tags: trunk)

Improvements to the makefile and README for MSVC. (check-in: b22b6140 user: mistachkin tags: trunk)
19:27
Ensure that if the "psow=0" URI option or FCNTL_POWERSAFE_OVERWRITE file-control is used to clear the power-safe overwrite flag, extra padding frames are added to the WAL file. (check-in: 48c821fd user: dan tags: trunk)
19:10
Change README to README.md and expand it. Remove unrelated and obsolete files. (check-in: 18d4e258 user: drh tags: trunk)

Minor simplifications to the "zeroPage()" routine in btree.c. (check-in: cc8f10bc user: drh tags: trunk)
21:31
Remove the "rowid cache" that sought to remember the largest rowid for a table and thereby speed up OP_NewRowid. That cache was ineffective. Removing it results in a performance increase of 0.4%, less memory usage, and a slightly smaller library size. (check-in: 56bc5ce8 user: drh tags: trunk)
15:05
Various fixes and test case updates so that veryquick.test passes again. (Leaf check-in: f352ef57 user: dan tags: deferred-open)

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.

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.

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)

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)
15:46
Fix the ".echo on" dot-command of the shell so that it echos comments in addition to SQL statements and dot-commands.

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.

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.

Avoid using the GetVersionEx functions if they are considered deprecated. (check-in: afdca299 user: mistachkin tags: trunk)
03:01
Avoid using the GetVersionEx functions if they are considered deprecated. (Closed-Leaf check-in: 0ea9e472 user: mistachkin tags: vs2013)
01:23
Add additional test cases for skip-scan. (check-in: 1ae4915d user: drh tags: trunk)

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)
21:18
Changing the CAST behavior of REAL values actually changed a documented requirement. So we also have to change the requirement evidence text to match. (check-in: d84aa44e user: drh tags: trunk)

Do not try to run the atof1.test test script on ARM hardware which lacks the "long double" type. (check-in: fafca560 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 SQLITE_CONFIG_WIN32_HEAPSIZE option to configure the maximum isolated heap size on Windows. (check-in: 914e6c9d user: mistachkin tags: trunk)
22:24
Change a while-loop into a do-loop in sqlite3VdbeRecordCompare() and add an assert() to verify that the do-loop really is appropriate. This gives about a 10% performance boost in that routine, or a 0.9% boost overall. (check-in: 011a6be4 user: drh tags: trunk)
21:49
Clarify docs for the SQLITE_CONFIG_WIN32_HEAPSIZE option. (Closed-Leaf check-in: 51e87607 user: mistachkin tags: winHeapSize)
21:41
Remove a NEVER() from a branch that is now reachable during OOM faults. (check-in: 18bdcb05 user: drh tags: trunk)
20:50
Optimizations to the sqlite3BtreeMovetoUnpacked() routine in storage engine making it about 17.8% faster, which in turn makes SQLite over 1.2% faster overall. (check-in: 032e8993 user: drh tags: trunk)
20:14
Return an SQLITE_CORRUPT error if the content size field of a table record extends off the end of a page. (Closed-Leaf check-in: b48c4e40 user: drh tags: btree-optimization)
17:38
Uses shifts rather than division for arithmetic on the cell indices, since those indices are always non-negative. (check-in: 5bf2a3fe user: drh tags: btree-optimization)
16:52
Optimize the skipping of the payload size field when doing a binary search for a rowid. (check-in: 55e5bfa2 user: drh tags: btree-optimization)

Arrange for sqlite3BtreeMovetoUnpacked() to always leave the cursor cell parse cache invalidated. This fixes issues with previous check-ins on this branch and also runs faster. (check-in: a7467560 user: drh tags: btree-optimization)
15:01
More optimizations to sqlite3BtreeMovetoUnpacked(). But there are failures in TH3. Committing this intermediate state to facilitate bisecting. (check-in: f80497be user: drh tags: btree-optimization)
14:10
More improvements to sqlite3BtreeMovetoUnpacked() performance. (check-in: 88680698 user: drh tags: btree-optimization)

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)
21:29
Add newlines at the end of some error messages in speedtest1. (check-in: 6b98f0af user: drh tags: trunk)

Changes some offset and amount parameters from "int" to "u32" to avoid harmless signed/unsigned comparison warnings. (check-in: 4e8c5d07 user: drh tags: trunk)
21:40
Modify wordcount so that timer information appears on standard error instead of standard output. Rename the run-wordcount.bash script to run-wordcount.sh and simplify it so that it stands a better chance of running on non-GNU systems. (check-in: 586c11ed user: drh tags: trunk)

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).

2013-10-26
15:40
Work on the UPDATE and INSERT logic. This is an incremental check-in so that can switch over to trunk to work on an unrelated issue there. (check-in: 086ec2a1 user: drh tags: omit-rowid)
13:36
Replace the OP_IsUnique opcode with OP_NoConflict. This code simplification might be useful to move onto trunk even if this branch is never merged. (check-in: e6650e16 user: drh tags: omit-rowid)

2013-10-24
19:48
Update the interface to the sqlite3GenerateRowDelete() utility so that it is able to handle WITHOUT ROWID tables. The implementation still needs to be completed. (check-in: 85daf517 user: drh tags: omit-rowid)
15:20
Add the ".open" command to the command-line shell. (check-in: 21eccb91 user: drh tags: trunk)

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)
14:28
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)
2013-10-21

2013-10-19
23:31
Experimental changes toward "index only" tables. Add the ability to specify options on CREATE TABLE statements using the WITH clause modeled after PostgreSQL and SQL Server. Only the "omit_rowid" option is currently recognized and that option is currently a no-op. (check-in: 0248ec5e user: drh tags: omit-rowid)
16:51
Improved header comment with better instructions on the vfslog.c extension. (check-in: 4bd592c8 user: drh tags: trunk)

20:03
Add the SQLITE_FCNTL_TRACE file control and generate it for OP_Trace when compiled with SQLITE_USE_FCNTL_TRACE. Update vfslog.c to make use of the new file control. Also update vfslog.c to log UNLOCK events before the fact, rather than afterwards. (check-in: e801f35a user: drh tags: trunk)
17:42

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.

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)

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)

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).

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.

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.

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)

Fix a bug in SQLITE_TRACE_SIZE_LIMIT that was introduced by check-in [1a1cf5aa86734c8]. That check-in was to remove harmless compiler warnings. So once again, we have introduced a real bug into SQLite by attempting to eliminate a harmless compiler warning. (check-in: cec2bcb4 user: drh tags: trunk)
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)

18:33
Enhance the command-line shell so that adding a non-zero numeric argument to the ".exit" command causes an immediate exit without cleaning up. This can be used (for example) to cause journal files to be left behind. (check-in: 8ba951d1 user: drh tags: trunk)
15:59
Add btree-page decoding logic to showwal.c. Commands of the form: "showwal $FILE 123bmc" show the content of the btree page in frame 123. "b" means decode the btree. "c" means show cell content. "m" means give a map of the btree page. (check-in: 93b159da user: drh tags: trunk)

Refactor collating-sequence handling as a fix for ticket [71e333e7d2e642]. The Expr.pColl field is removed from the Expr object.

Fix some corner case behavior in the new ORDER BY optimization logic. Remove the SQLITE_OrderByIdx bit from the SQLITE_TESTCTRL_OPTIMIZATIONS mask, since enabling it caused many TH3 tests to fail when the NO_OPT configuration parameter was engaged, and since there really isn't any need to turn that optimization off.
