16:20
Change the name of SQLITE_FCNTL_SYNC to SQLITE_FCNTL_SYNC_OMITTED and only send it when PRAGMA synchronous=OFF. Add better documentation to explain what that file-control opcode is used for. (check-in: 6491498085 user: drh tags: trunk)
13:43
Fix a couple of typos in comments. No changes to actual code. (check-in: 9167fdb356 user: dan tags: trunk)
11:33
Fix a broken assert() in pager.c. (check-in: 13108ce13c user: dan tags: trunk)
09:54
Fix a problem in memsubsys1.test. Modifications to test code only. (check-in: 7ef3f7cba7 user: dan tags: trunk)
04:34
Shave a few cycles so that performance is better than 3.7.4 in speed tests. (check-in: e146493011 user: drh tags: trunk)
2011-01-24
20:18
Modify the test_quote.c demonstration shim so that it works when SQLITE_THREADSAFE=0 is defined. (check-in: b70bcccaf5 user: drh tags: trunk)
19:45
Fix a typo in the documentation for sqlite3_snprintf(). No changes to code. (check-in: 8d1065411a user: drh tags: trunk)
19:14
Fix a harmless compiler warning (a shadowed local variable) in analyze.c. (check-in: a1ad7fb38b user: drh tags: trunk)
17:46
Restructuring and generalizing analyze5.test. The whole script is currently disabled and will need to be reenabled prior to merging with trunk. (check-in: 31fcc7067b user: drh tags: stat2-enhancement)
16:00
Ensure that if a deferred FK constraint is violated by a statement that creates its own implicit transaction, the statement is not an "active-write" after sqlite3_step() returns. (Closed-Leaf check-in: 8063197ef1 user: dan tags: deferred-fk-quirk)
15:11
Change the cost estimator in the query planner to take into account the logN rowid lookup cost when going from an index to a table. (check-in: b442525b0b user: drh tags: stat2-enhancement)
2011-01-22
13:32
Modify the trace callback mechanism so that SQL commands executed from within virtual table or user function callbacks are passed to the trace callback without parameter expansion and enclosed in SQL comments. (check-in: a764915b87 user: dan tags: trunk)
00:10
Add the ability to use indices for constraints of the form "x IS NOT NULL" when sqlite_stat2 is available and most entries for column x are NULL. (check-in: 5d5bddd290 user: drh tags: stat2-enhancement)
2011-01-21
18:25
Change sqlite3StrAccumAppend() to use realloc instead of malloc. (check-in: 380f61df07 user: dan tags: trunk)
18:18
Adjustments to the result row estimator for the IN operator so that it gives the same estimates as the equivalent OR operator. Test cases for the same. (check-in: c82cb9c028 user: drh tags: stat2-enhancement)
16:27
Make use of histogram data to make better estimates for the number of rows that will be returned from "x IN (v1,v2,v3,...)" constraints. (check-in: fd3977a27a user: drh tags: stat2-enhancement)
15:52
Add options to test command [do_faultsim_test] to support testing VFS implementations. (check-in: 503ad889da user: dan tags: trunk)
14:37
Add the ability to use indices when a range contraint is bounded on the lower end by NULL. (check-in: f73a167b43 user: drh tags: stat2-enhancement)
2011-01-20
20:36
Update ANALYZE test cases to check out the use of histograms for equality constraints. (check-in: c7b59afaf0 user: drh tags: stat2-enhancement)
16:52
Use histogram data to improve the row-count estimates on equality constraints. (check-in: 6bfc5c69eb user: drh tags: stat2-enhancement)
02:56
The first of a planned series of enhancements to the query planner that enable it to make better use of sqlite_stat2 histograms when the table has many repeated values. (check-in: 2cd374cd23 user: drh tags: stat2-enhancement)
2011-01-19
21:58
Comment improvements in pcache1.c. No changes to code. (check-in: 9660a0a225 user: drh tags: trunk)
2011-01-18
17:34
Pull over all the latest trunk changes. (check-in: ca86d04be1 user: drh tags: wal-trace-375)
17:03
Do not use mutexes in the pcache implementation unless SQLITE_ENABLE_MEMORY_MANAGMENT is defined. This is a performance enhancement. A side effect is that pcaches will not steal pages from one another unless ENABLE_MEMORY_MANAGEMENT is set, or unless SQLITE_THREADSAFE=0. (check-in: e5ca59e63b user: drh tags: trunk)
16:13
Get all test cases working with the mutex-free-pcache implementation. (Closed-Leaf check-in: 2dc98d2999 user: drh tags: mutex-free-pcache)
15:17
Do not use SQLITE_MUTEX_STATIC_MEM2 since it has been reused as STATIC_OPEN. Instead, create a new static mutex STATIC_PMEM which is an alias for the unused STATIC_LRU2. (check-in: f1cf02efcb user: drh tags: mutex-free-pcache)
2011-01-17
21:32
Here is a completely new implementation of the mutex-free-pcache. This one uses a common code base and automatically selects whether or not to use mutexes depending on compile-time and start-time options. (check-in: d094a1bfb7 user: drh tags: mutex-free-pcache)
18:30
Fix a typo in the documentation for sqlite3_stmt_readonly(). (check-in: 56417a3386 user: drh tags: trunk)
17:42
Add the SQLITE_OMIT_AUTORESET compile-time option which if enabled causes the sqlite3_step() routine to return SQLITE_MISUSE if it is called after it has previously returned anything other than SQLITE_ROW, SQLITE_BUSY, or SQLITE_LOCKED. (check-in: 053ce76deb user: drh tags: trunk)
02:24
Add back an ALWAYS() to regain full test coverage. (check-in: b93f6f3e67 user: drh tags: trunk)
2011-01-16
22:37
On a backup from a smaller to a larger page size, do not begin committing the transaction until the source pages after the pending byte have been copied. (check-in: 612e2599d3 user: drh tags: trunk)
00:56
Make sure the change-counter and SQLite-version fields of the header are set correctly even when doing a VACUUM with locking_mode=EXCLUSIVE. Ticket [5d863f876ee9561b]. (check-in: 04fa1e1690 user: drh tags: trunk)
2011-01-15
21:42
Make sure the change counter and SQLite version numbers in the header are set correctly, even when running in WAL mode and when VACUUMing in WAL mode. Ticket [5d863f876ee9561b9]. (check-in: 0be92a7576 user: drh tags: trunk)
18:11
Fix the change-counter increment for WAL pages so that it works even when invoked from xStress. Ticket [5d863f876ee9561b95e2]. (Closed-Leaf check-in: 228e7c34c6 user: drh tags: bug-5d863f87)
17:12
Increment the change counter and update the SQLite version number whenever page 1 is added to the WAL. Ticket [5d863f876ee9561b9] (check-in: c1e0d09cd3 user: drh tags: bug-5d863f87)
16:52
Add a test case demonstrating the problem described by ticket [5d863f876e]. (check-in: af54963f0f user: dan tags: trunk)
2011-01-14
16:43
Rerun autoconf to bring the configure script up-to-date. (check-in: 142174640d user: drh tags: trunk)
16:12
Provide an alternative and experimental pcache implementation that avoids the use of mutexes at the expense of using more memory. (Closed-Leaf check-in: 2ea5bd1287 user: drh tags: mutex-free-pcache)
15:17
Fix comments, including some documentation comments, in the page cache logic. No code changes. (check-in: c80e9c1a0d user: drh tags: trunk)
11:51
Fix a bug in test code (test_vfs.c). (check-in: 772a3845f8 user: dan tags: trunk)
2011-01-13
16:10
Fix a typo on the sqlite3_open_v2() documentation. (check-in: b0add45abc user: drh tags: trunk)
11:20
Fix a couple of crashes in fts3 that can occur if the database contents are inconsistent. (check-in: 811e12cddf user: dan tags: trunk)
10:58
Fix a segfault that can occur in matchinfo if an fts4 table contains mostly zero-length documents. Specifically, if the table contains more rows than it does bytes of text. (check-in: fe9047668e user: dan tags: trunk)
2011-01-12
17:56
Do not raise an SQLITE_CORRUPT error in Recoverymode if the database size in the header is larger than the physical file size. This facilitates recovery of a database in which the database size field has been corrupted. (check-in: 114640d920 user: drh tags: trunk)
2011-01-11
17:40
Merge accidentally created fork. (check-in: b7d080b8e8 user: dan tags: trunk)
17:39
Add the SQLITE_FCNTL_SYNC file-control. (check-in: b3f2f465c3 user: dan tags: trunk)
17:38
Change the page size of the destination database in a backup, if it is changeable, prior to starting the backup. (check-in: a5e4e0caad user: drh tags: trunk)
16:09
If a rollback is attempted in journal_mode=off mode, force SQLite to discard the contents of the pager cache before processing any subsequent queries. (check-in: ece7efce27 user: dan 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: 3513bf6ee0 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: d1b3c54f42 user: drh tags: step-autoreset)
2011-01-10
21:01
Update pager requirements to account for the ZIPVFS extension. (check-in: d94e59b514 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: 378a1d13af 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: cda5eab18f 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: 57ffa07e26 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: 65a13faf1e user: drh tags: trunk)
21:20
Enhancements to the "showdb" debugging tool. Add the ability to display the content of a cell. (check-in: e9023a4e1e user: drh tags: trunk)
13:43
Increment the version number to 3.7.5. (check-in: 9ec3896e2f user: drh tags: trunk)
12:20
Add the sqlite3_vsnprintf() interface. (check-in: fc67adea41 user: drh tags: trunk)
2011-01-04
20:06
Fix a null-pointer dereference that can occur on an OOM error while running ANALYZE with SQLITE_ENABLE_STAT2. (check-in: 73128d4ef5 user: drh tags: trunk)
19:01
Fix the ANALYZE command so that it takes collating sequences into account when gathering index statistics. (check-in: a5867cfc4c 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: 824c8dd301 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: 430635dacf user: dan tags: trunk)
10:49
Fix some off-by-one errors in the comments for API functions create_function() and value_blob(). No changes to code or tests. (check-in: 7ded90baeb 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: 7088d9450f user: dan tags: trunk)
2010-12-22
21:48
Do not include <sys/mmap.h> if SQLITE_OMIT_WAL is defined. (check-in: b82e85ece9 user: drh tags: trunk)
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: b0888047bb 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: 8c3b06c299 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: 09f6c053ff 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: 39bbd35599 user: drh tags: trunk)
2010-12-20
17:00
Clarify the documentation of the SQLITE_STATUS_MALLOC_COUNT parameter to sqlite3_status(). (check-in: 3b41bcc3e3 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: 34613f1dc5 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: 74fff69234 user: drh tags: trunk)
01:00
Fix minor typos in the sqlite3_backup documentation. (check-in: df430be59d user: drh tags: trunk)
2010-12-16
20:35
Improvements to the documentation for sqlite3_backup. No code changes. (check-in: f83609f470 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: 70a3d81742 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: cf86affcb7 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: d0e4375b8a 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: e1660764f2 user: drh tags: trunk)
2010-12-10
17:06
Fix a performance regression in matchinfo(). (check-in: fa37d8eb7c user: dan tags: trunk)
2010-12-09
19:15
Add support for the SQLITE_DEFAULT_FOREIGN_KEYS compile-time option. (check-in: c959945ab7 user: drh tags: trunk)
18:55
Mention the SQLITE_DEFAULT_WAL_AUTOCHECKPOINT compile-time option in the documentation for the sqlite3_wal_autocheckpoint() interface. (check-in: 5a52dd59ff 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: 9c19b7ae35 user: drh tags: trunk)
03:28
The command-line shell ignore errors in sqlite3_close() when shutting down. (check-in: 925332c3d7 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: e474fd9e7f user: drh tags: trunk)
2010-12-07
23:24
Improved documentation for SQLITE_FCNTL_FILE_POINTER. (check-in: 43935548ae user: drh tags: trunk)
20:14
Version 3.7.4 (check-in: a586a4deeb user: drh tags: trunk, release, version-3.7.4)
17:12
Work around restriction in Windows file locking. (check-in: fe441df9ba user: shaneh tags: trunk)
16:39
Fix a bug in the demo "superlock" code preventing locks from being released in some circumstances. (check-in: 65c393793f user: dan tags: trunk)
14:59
Version 3.7.4 release candidate 3 (check-in: 11c74c0dae user: drh tags: trunk)
14:32
Run some of the existing test scripts with optimizations disabled as part of all.test. (check-in: b0634d2f90 user: dan tags: trunk)
07:57
Add tests to tkt-80ba201079.test. (check-in: c370338c77 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: fabcb6b95e user: drh tags: trunk)
21:06
Add the ability to disable constant factoring using sqlite3_test_control(). Add a TCL interface to this new capability and add tests cases to the TCL test scripts to actually use the new capability. (check-in: ad8bc68197 user: drh tags: trunk)
18:59
Back out part of the previous change that was not really necessary in order to fix [80ba201079ea60], and which in fact serves no useful purpose. (check-in: fa9eef865f user: drh tags: trunk)
18:50
Initialize all constants at the very beginning of a prepared statement. Do not allow constant initialization to occur once control flow has a chance to diverge, to avoid the possibility of having uninitialized registers. Ticket [80ba201079ea60807]. (check-in: c5c53152d6 user: drh tags: trunk)
17:11
Have sqlite3_blob_bytes() return 0 following a failed call to sqlite3_reopen_blob(). (check-in: 476a8b4921 user: dan tags: trunk)
2010-12-04
19:35
Version 3.7.4 release candidate 2. (check-in: 40756fe1f1 user: drh tags: trunk)
18:20
Fix a memory leak in fts3 that can occur in an OOM condition. (check-in: 507027b70f user: dan tags: trunk)
2010-12-03
18:57
Remove an over-zealous call to memAboutToChange() from OP_MustBeInt. OP_MustBeInt will never invalidate the Mem.z pointer so the memAboutToChange() call is not necessary. (check-in: 841cf7a7db user: drh tags: trunk)
15:41
Version 3.7.4 release candidate 1 (check-in: 2e800cb87d user: drh tags: trunk)
15:04
Add tests for fts3 to backcompat.test. (check-in: b4eafde823 user: dan tags: trunk)
