Update mutex1.test so that it works with the memsubsys1 permutation (pagecache memory). Change a few instances of SQLITE_MUTEX_STATIC_LRU2 in comments and test code to STATIC_PMEM. check-in: 456bd5c6 user: dan tags: trunk
06:13
Changes to exclusive2.test to make it more deterministic. check-in: 84b0c2bc user: dan tags: trunk
00:07

Ensure that if a deferred FK constraint is violated by a statement that creates its own implicit transaction, the statement is not an "active-write" after sqlite3_step() returns. Closed-Leaf check-in: 8063197e user: dan tags: deferred-fk-quirk
15:11
Change the cost estimator in the query planner to take into account the logN rowid lookup cost when going from an index to a table. check-in: b442525b user: drh tags: stat2-enhancement
2011-01-22
13:32

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: 5d5bddd2 user: drh tags: stat2-enhancement
2011-01-21
18:25
Change sqlite3StrAccumAppend() to use realloc instead of malloc. check-in: 380f61df user: dan tags: trunk
18:18

17:03
Do not use mutexes in the pcache implementation unless SQLITE_ENABLE_MEMORY_MANAGMENT is defined. This is a performance enhancement. A side effect is that pcaches will not steal pages from one another unless ENABLE_MEMORY_MANAGEMENT is set, or unless SQLITE_THREADSAFE=0. check-in: e5ca59e6 user: drh tags: trunk
16:13

2011-01-17
21:32
Here is a completely new implementation of the mutex-free-pcache. This one uses a common code base and automatically selects whether or not to use mutexes depending on compile-time and start-time options. check-in: d094a1bf user: drh tags: mutex-free-pcache
18:30
Fix a typo in the documentation for sqlite3_stmt_readonly(). check-in: 56417a33 user: drh tags: trunk
17:42
Add the SQLITE_OMIT_AUTORESET compile-time option which if enabled causes the sqlite3_step() routine to return SQLITE_MISUSE if it is called after it has previously returned anything other than SQLITE_ROW, SQLITE_BUSY, or SQLITE_LOCKED. check-in: 053ce76d user: drh tags: trunk
02:24
Add back an ALWAYS() to regain full test coverage. check-in: b93f6f3e 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: 612e2599 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: 04fa1e16 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: 0be92a75 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: 228e7c34 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: c1e0d09c user: drh tags: bug-5d863f87
16:52
Add a test case demonstrating the problem described by ticket [5d863f876e]. check-in: af54963f user: dan tags: trunk
2011-01-14
16:43
Rerun autoconf to bring the configure script up-to-date. check-in: 14217464 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: 2ea5bd12 user: drh tags: mutex-free-pcache
15:17

Fix a typo on the sqlite3_open_v2() documentation. check-in: b0add45a user: drh tags: trunk
11:20
Fix a couple of crashes in fts3 that can occur if the database contents are inconsistent. check-in: 811e12cd 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: fe904766 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: 114640d9 user: drh tags: trunk
2011-01-11
17:40
Merge accidentally created fork. check-in: b7d080b8 user: dan 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: ece7efce 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: 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

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
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: 7ded90ba 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
21:48
Do not include <sys/mmap.h> if SQLITE_OMIT_WAL is defined. check-in: b82e85ec 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: 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

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

2010-12-10
17:06
Fix a performance regression in matchinfo(). check-in: fa37d8eb user: dan tags: trunk
