18:10
In the "unix-excl" VFS, use the heap for shared memory, since only a single process is able to read or write the database. (Closed-Leaf check-in: a05a6d40 user: drh tags: unix-excl)
17:22
Fix some issues with UPDATE changes in the session module. (check-in: 57862efe user: dan tags: sessions)
17:02
Add the new optional "unix-excl" VFS. This VFS grabs an exclusive lock on the database preventing other processes from accessing it, but continues to allow other database connections from the same process. (check-in: 00051c32 user: drh tags: unix-excl)
04:58
More tests for SQLITE_OMIT_UNIQUE_ENFORCEMENT and minor change to implementation. (check-in: b8699943 user: shaneh tags: trunk)

19:22
Add start of sessions feature. (check-in: 269a81a3 user: dan tags: sessions)
16:39
Merge the syscall-override changes into trunk. (check-in: 36d79e6f user: drh tags: trunk)

2011-03-05
21:41
Simplifications to the overflow-free multiplier. Also remove some commented-out code that was left in that subroutine by mistake on the previous check-in. (check-in: 55fc25fd user: drh tags: trunk)
20:59
Fix all known instances of signed-integer overflow. Within SQL expressions, integer overflow now forces coercion to floating point. The shift operators work with any integer right-hand operand with negative values reversing the direction of the shift. (check-in: abf21394 user: drh tags: trunk)
13:54
Fix an instance of signed arithmetic overflow and an one bit-shift overflow. Mark six other signed arithmetic overflow locations that need fixing. (check-in: 04abab71 user: drh tags: trunk)

15:09
Proof-of-concept prototype for the proposed xSetSystemCall extension method on the VFS. (check-in: 92b5a76a user: drh tags: syscall-override)
02:08
Log all error from close() in os_unix.c to sqlite3_log() but do not attempt to report errors back up to the application. Update the unix error logging to put the most important information earlier in the message. (check-in: 7b6e30e6 user: drh tags: trunk)
2011-03-01
18:42

2011-02-17
15:58
Remove a no-op code path from sqlite3ExprIsInteger(). Replace it with an assert() that proves it always does nothing. (check-in: 7af66d1b user: drh tags: trunk)

17:46
Prevent a segfault when automatic indices try to use a column with an unknown collating function. Ticket [77aa3b1e6592582e38605d36]. This check-in also removes some stray \r characters unrelated to the problem. (check-in: f01030a0 user: drh tags: trunk)
00:08
Refactor the cost function in the query planner. Give extra cost (thus reduce likelihood of selection) to full table scans. (check-in: 878da276 user: drh tags: trunk)
2011-02-09
19:55
Make sure code *compiles* with each OMIT and ENABLE option. Mostly changes to test modules. (check-in: 7cc515ed user: shaneh tags: trunk)

Update Makefile.in for fts3_aux changes. (check-in: 38b7cb33 user: shaneh tags: trunk)
03:04
Use macros to define the relative costs of search and seek operations when computing costs in the query planner. Current constants seems wrong and need to be fixed, but doing so will alter test results. Need more experimentation to determine accurate relative costs. (check-in: 5f2ec44b user: drh tags: trunk)
03:03
Simplifications to the sqlite3_wal_checkpoint_v2() logic. (check-in: 652b8835 user: drh tags: trunk)
2011-02-07
23:56
Cleanup to the OP_Checkpoint opcode. (check-in: f611a5a8 user: drh tags: trunk)
16:24
Fix some test cases in walfault.test. Extend one test case to restore code coverage. Add wal5.test to the "coverage-wal" permutation. (check-in: f83b07ac user: dan tags: trunk)
15:12
Change blocking-checkpoint tests so that they run once using "PRAGMA wal_checkpoint" and once using calls to sqlite3_wal_checkpoint_v2(). Also fix edge cases surrounding the output variables set by wal_checkpoint_v2(). (check-in: 5a4b6652 user: dan tags: trunk)
2011-02-05
15:47
Ensure fts4aux can handle a table name in single or double quotes as a constructor argument. (check-in: 929d62e4 user: dan tags: trunk)

Merge the stat2 query planner enhancements into the trunk. (check-in: 499edcbc user: drh tags: trunk)
05:47
If a deferred foreign key constraint fails on a statement that is not part of a larger transation, make sure that the statement fully ends so that subsequent invocations of the same statement will not pass the constraint because they think the transaction is not closed. This is a merge of the deferred-fk-quirk branch together with a test case. (check-in: 2f94d462 user: drh tags: trunk)
00:51
Fix the ATTACH command so that the filename argument can be any expression and so that if authorizer callback gets a NULL pointer for the filename if the filename argument is anything other than a string literal. Ticket [9013e13dba5b58c7] (check-in: e64e1453 user: drh tags: trunk)
2011-02-03

Add test script pagerfault3.test. No changes to code or existing tests. (check-in: 682fe41e user: dan tags: trunk)
15:46
Change pager_truncate() to a different method for extending files while also ensuring that writes are page-size and page-aligned. (check-in: 874bc884 user: drh tags: trunk)
15:07
When extending a database file, do so by writing one or more page-size chunks of data to the file, instead of just a single byte to the end. (check-in: 58577135 user: dan tags: trunk)

2011-01-26
19:46
Update all built-in VFSes to return SQLITE_OK for the SQLITE_FCNTL_SYNC_OMITTED file-control operation. Also change the xFileControl methods to return SQLITE_NOTFOUND for unrecognized operation codes. (check-in: 6f2c72a0 user: drh tags: trunk)
15:23
Update test file mutex1.test to account for [e3b500fb5d]. (check-in: c86e46f4 user: dan tags: trunk)

07:25
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
Rename the PCache1.mxPinned field to n90pct (since it is 90% of nMax) in order to distinguish it from PGroup.mxPinned. Fix the computation of n90pct so that it does not overflow adversely on excessively large cache sizes. (check-in: c85202ba user: drh tags: trunk)
2011-01-25
18:30
Fix new compiler warnings in pcache1.c that were introduced by the recent performance enhancement patches of [e14649301138b684]. (check-in: c17703ec user: drh tags: trunk)
18:19
Add a missing call to sqlite3PagerSync() removed by [ce552d975] to the backup code. (check-in: 1965b853 user: dan tags: trunk)
16:48
Make sure the return code from doing an xSync is correctly initialized so that a valid return code is produced regardless of the path taken through the logic. (check-in: f12b5d76 user: drh tags: trunk)
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: 64914980 user: drh tags: trunk)
13:43
Fix a couple of typos in comments. No changes to actual code. (check-in: 9167fdb3 user: dan tags: trunk)
11:33
Fix a broken assert() in pager.c. (check-in: 13108ce1 user: dan tags: trunk)
09:54
Fix a problem in memsubsys1.test. Modifications to test code only. (check-in: 7ef3f7cb user: dan tags: trunk)
04:34
Shave a few cycles so that performance is better than 3.7.4 in speed tests. (check-in: e1464930 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: b70bccca user: drh tags: trunk)
19:45
Fix a typo in the documentation for sqlite3_snprintf(). No changes to code. (check-in: 8d106541 user: drh tags: trunk)
19:14
Fix a harmless compiler warning (a shadowed local variable) in analyze.c. (check-in: a1ad7fb3 user: drh tags: trunk)
2011-01-22
13:32

2011-01-18
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
Get all test cases working with the mutex-free-pcache implementation. (Closed-Leaf check-in: 2dc98d29 user: drh tags: mutex-free-pcache)

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: f1cf02ef user: drh tags: mutex-free-pcache)
2011-01-17

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)

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)

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)

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

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: fa9eef86 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: c5c53152 user: drh tags: trunk)
