Fix another issue to do with window-functions in aggregate queries. (check-in: 6413e38a17 user: dan tags: exp-window-functions)
19:35
Documentation update: clarify that sqlite3_errcode() and related interfaces do not themselves modify the error code. (check-in: 858fc52b23 user: drh tags: trunk)
19:22
Documentation updates: clarify the behavior of sqlite3_column and sqlite3_value interfaces following an OOM error. (check-in: 428c581e4b user: drh tags: trunk)
18:40
Fix some problems with using window-functions in aggregate queries. (check-in: fe7081e095 user: dan tags: exp-window-functions)
13:52
Improvements to SCopy correctness tracking when SQLITE_DEBUG is enabled. (check-in: b2973f2357 user: drh tags: trunk)
13:16
Fix the "Synopsis" on the OP_BitNot opcode. (check-in: acd78df611 user: drh tags: trunk)

23:44
Ensure pointer map entries are always added when a row that does use overflow pages replaces one that does not in an auto-vacuum database. Fix for [fda22108]. (check-in: 30c50f0e06 user: drh tags: branch-3.18)

13:49
Add a fast-path implementation of pcache1Fetch() for the common case of separate caches that do not use a mutex. (check-in: 760700edb3 user: drh tags: faster-pcache1-fetch)
13:04
Minor performance optimization in pcache1.c. (check-in: 2e8ad2ead9 user: drh tags: trunk)
12:54
Add the OP_ColumnsUsed opcode (when compiled with SQLITE_ENABLE_COLUMN_USED_MASK) as a hint to the b-tree layer as to which columns of a btree cursor will be used. (check-in: 711a176cbf user: drh tags: trunk)

17:10
Increase the WAL-mode SQLITE_PROTOCOL timeout to 10 seconds. (check-in: 2aeacf81df user: drh tags: trunk)
15:46

Change lemon so that it does not generate yytestcase() macros on destructor cases since destructors are commonly unreachable in a reasonable grammar. For the reduce-rule switch, gather all no-ops into the "default:" case. (CVS 6757) (check-in: caebfe82cb user: drh tags: trunk)
15:47
The previous check-in ((6755)) put in more yytestcase() macros than are called for. This check-in addresses that problem. (CVS 6756) (check-in: a5b182f93b user: drh tags: trunk)
13:53
The lemon parser generator now inserts yytestcase() macros on reduce action and on each destructor, to verify that all have been executed. yytestcase() is a no-op by default but can be set to something more useful inside of %include. (CVS 6755) (check-in: fe9c917734 user: drh tags: trunk)
12:50
In lemon: omit unused entries from the end of the yyFallback array. (CVS 6754) (check-in: 9cfbe2ba68 user: drh tags: trunk)
12:04
Enable the SQLITE_LIMIT_FUNCTION_ARG limiter. (CVS 6753) (check-in: a17e331717 user: drh tags: trunk)
11:42
Remove a C++-ism from the code. Ticket #3912. (CVS 6752) (check-in: bc729bc3e6 user: drh tags: trunk)
03:47
An additional memory leak in the parser fixed. Ticket #3911. (CVS 6751) (check-in: 6197b49271 user: drh tags: trunk)
03:27
Make sure nested queries with USING clauses do not leak memory. Preliminary fix for ticket #3911. (CVS 6750) (check-in: bd341a103c user: drh tags: trunk)
02:27
Modifications to the parser to eliminate unreachable code. (CVS 6749) (check-in: 457e0b245b user: drh tags: trunk)

The VDBE aggregate functions use an in-memory btree instead of a disk-based btree for improved performance. (CVS 1579) (check-in: 8029f1e465 user: drh tags: trunk)
20:12
Speed up in the handling of VDBE cursors. (CVS 1578) (check-in: e42316f570 user: drh tags: trunk)
18:12
Improve the speed of OP_Column through better caching. (CVS 1577) (check-in: f687977a28 user: drh tags: trunk)
14:11
Fix typo in the locking document. (CVS 1576) (check-in: 99a7bd83ac user: drh tags: trunk)
09:25
(1) Modifications to the user-function interface and (2) Internal changes to automatically created indices. (CVS 1575) (check-in: 5903f53828 user: danielk1977 tags: trunk)
02:17
Bug fix in the unix locking code. (CVS 1574) (check-in: dcad244f58 user: drh tags: trunk)
01:43
Change prototype for busy callbacks to "int xBusy(void *, int);" (CVS 1573) (check-in: 4f1cfca5ca user: danielk1977 tags: trunk)
00:42
Use the SQLITE_UTF* symbols instead of the old internal TEXT_Utf* symbols. (CVS 1572) (check-in: 9b84f2f488 user: danielk1977 tags: trunk)
