2011-02-20
03:22
Backport the sqlite3.h generator fix so that it works with newer versions of Fossil. See [3513bf6ee090d9b] for the original. check-in: 29597a71 user: drh tags: branch-3.7.4
03:20
Backport the changes of checkin [cf86affcb7d308949] ("Make wal_checkpoint a no-op if a prior checkpoint has already copied all WAL content into the database.") to the 3.7.4 release. check-in: e6e540ab user: drh tags: branch-3.7.4
03:11
Backport the SQLITE_PROTOCOL fix and the extra defensive measure to version 3.7.4. check-in: bcc22c4b user: drh tags: branch-3.7.4

17:40
Merge accidentally created fork. check-in: b7d080b8 user: dan tags: trunk
17:39

17:38
Change the page size of the destination database in a backup, if it is changeable, prior to starting the backup. check-in: a5e4e0ca user: drh tags: trunk

12:46
Fix the sqlite3.h generator script so that it generates the correct SQLITE_SOURCE_ID string with the latest versions of Fossil that include fractional seconds on the date/time stamp. check-in: 3513bf6e 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
2011-01-10
21:01
Update pager requirements to account for the ZIPVFS extension. check-in: d94e59b5 user: drh tags: trunk
2011-01-07
02:50
Reorder the fields in private structures in an effort to reduce alignment gaps and thus make the structures smaller, and to put frequently accessed fields first. Also update some obsolete comments. Valgrind shows a very slight performance improvement. check-in: 378a1d13 user: drh tags: trunk
2011-01-06
15:51
Enhance the showdb tool to show overflow page pointers at the end of overflow cells. check-in: cda5eab1 user: drh tags: trunk
01:26
Enhance the showdb tool to show a btree page layout. Add limit checks so that overflow content does not overflow the buffer. check-in: 57ffa07e user: drh tags: trunk
2011-01-05
21:46
Fix a bug in the showdb utility: the serial types for BLOB and TEXT where reversed. check-in: 65a13faf user: drh tags: trunk

12:20
Add the sqlite3_vsnprintf() interface. check-in: fc67adea user: drh tags: trunk

Fix a null-pointer dereference that can occur on an OOM error while running ANALYZE with SQLITE_ENABLE_STAT2. check-in: 73128d4e user: drh tags: trunk
19:01
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
2010-12-29
18:24
Have testfixture invoke C routine Zipvfs_Init() when creating a new interpreter if SQLITE_ENABLE_ZIPVFS is defined. check-in: 430635da user: dan tags: trunk

2010-12-24
15:49
Reduce the number of calls to sqlite3_realloc() made by fts3 when querying for position information of a term prefix. check-in: 7088d945 user: dan tags: trunk
2010-12-22

2010-12-21
21:28
Add test cases for the new lookaside hit and miss status outputs. Add the output of lookaside hit and miss to the command-line shell statistics. check-in: b0888047 user: drh tags: trunk
20:36
Merge into the trunk the experimental enhancements to sqlite3_db_status() for measuring lookaside memory allocator performance. check-in: 8c3b06c2 user: drh tags: trunk
00:20
Remove the obsolete compile-time option SQLITE_THREAD_OVERRIDE_LOCK from the autoconf makefile. Needed only for LinuxThreads, which we no longer support. check-in: 09f6c053 user: drh tags: trunk
00:16
Rearrange a variable declaration in the proxy locking code to avoid a harmless compiler warning on recent MacOS versions. check-in: 39bbd355 user: drh tags: trunk
2010-12-20
17:00
Clarify the documentation of the SQLITE_STATUS_MALLOC_COUNT parameter to sqlite3_status(). check-in: 3b41bcc3 user: drh tags: trunk
15:51
Add additional DBSTATUS options for measuring the hit and miss rates against the lookaside memory pool - information useful in tuning the lookaside size. Currently experimental pending analysis of performance impact. Closed-Leaf check-in: 34613f1d user: drh tags: experimental
2010-12-17
14:03
Add the "-heap" option to the command-line shell - to allocate a fixed heap for use with SQLITE_ENABLE_MEMSYS5. check-in: 74fff692 user: drh tags: trunk
01:00
Fix minor typos in the sqlite3_backup documentation. check-in: df430be5 user: drh tags: trunk

20:35
Improvements to the documentation for sqlite3_backup. No code changes. check-in: f83609f4 user: drh tags: trunk
19:52
Fix an assertion fault that can only occur if SQLITE_ENABLE_STAT2 is defined and the constant folding optimization is disabled using sqlite3_test_control(). Problem introduced by [ad8bc68197f2b4] but we missed it prior to the 3.7.4 release due to taking shortcuts and skipping tests in the release checklist. check-in: 70a3d817 user: drh tags: trunk
02:06
Make wal_checkpoint a no-op if a prior checkpoint has already copied all WAL content into the database. This prevents a concurrent write to the database from resetting the wal-index out from under the WalIterator of the checkpoint as it is initializing. check-in: cf86affc user: drh tags: trunk
2010-12-15
21:02
Enhanced comments in wal.c and declare some procedure parameters "const". No changes to the generated code. check-in: d0e4375b user: drh tags: trunk
18:54
When registering the built-in LIKE and GLOB functions, make sure that they are tagged with SQLITE_UTF8 so that if other application-defined LIKE and GLOB implementations are provided for UTF16, then the appropriate function will be selected. check-in: e1660764 user: drh tags: trunk
2010-12-10
17:06

18:55
Mention the SQLITE_DEFAULT_WAL_AUTOCHECKPOINT compile-time option in the documentation for the sqlite3_wal_autocheckpoint() interface. check-in: 5a52dd59 user: drh tags: trunk
2010-12-08
18:30
Update the sqlite3_stmt_readonly() interface so that its output is well-defined for all prepared statements, and so that it gives the correct result for VACUUM. check-in: 9c19b7ae user: drh tags: trunk
03:28
The command-line shell ignore errors in sqlite3_close() when shutting down. check-in: 925332c3 user: drh tags: trunk
00:02
Changes to the shell which should, in theory, allow it to work with libeditline as an alternative to libreadline. check-in: e474fd9e user: drh tags: trunk
2010-12-07
23:24

15:49
Merge in all changes to the trunk through version 3.7.4rc3. check-in: d2ccf7fc user: drh tags: apple-osx
14:59
Version 3.7.4 release candidate 3 check-in: 11c74c0d user: drh tags: trunk
14:32
Run some of the existing test scripts with optimizations disabled as part of all.test. check-in: b0634d2f user: dan tags: trunk
07:57
Add tests to tkt-80ba201079.test. check-in: c370338c user: dan tags: trunk
2010-12-06
21:09
Fix the build so that it once again works with SQLITE_OMIT_SHARED_CACHE and SQLITE_OMIT_AUTOVACUUM. check-in: fabcb6b9 user: drh tags: trunk
