02:28
Make sure all bytes of the WAL file are initialized even if the checksums are not being computed until commit due to WAL overwrite. check-in: 1f44a9bd user: drh tags: trunk
02:00
Fix an uninitialized field in the Select object when SELECTTRACE is enabled. check-in: fc628516 user: drh tags: trunk
00:37
Various #ifdef enhancements for improved VxWorks support. check-in: 75cd41ff user: drh tags: trunk
2016-01-11
22:58
Performance optimization in the sqlite3VdbeChangeP4() routine of the code generator. check-in: 28bd8d5f user: drh tags: trunk
22:43
Fix duplicate test number in 'waloverwrite'. check-in: f5fb8268 user: mistachkin tags: trunk
18:05
Performance optimization on the Column opcode. check-in: ecc98bef user: drh tags: trunk
14:19
Performance optimization in sqlite3WalkExpr(). check-in: 2f8bd5fa user: drh tags: trunk
12:52
Increase the version number to 3.11.0 due to the WAL overwrite enhancement. check-in: 8e807bfa user: drh tags: trunk
12:13
If a single page is written to the wal file more than once, instead of appending the second and subsequent copy to the wal file, overwrite the first. Update: See the important bug fix at [f694e60a]! check-in: d493d4f1 user: dan tags: trunk
08:12
Add a test case to waloverwrite.test to check that savepoint rollback does not cause a problem. Closed-Leaf check-in: 87dae56c user: dan tags: wal-overwrite-frames
03:48
Slightly smaller and faster LIKE/GLOB comparison implementation. check-in: 5dddcc78 user: drh tags: trunk
00:52

2016-01-09
23:55
All WAL frame overwrites even if there are active savepoints. This is safe because a ROLLBACK TO will cause all reverted pages to be rewritten to the WAL file prior to COMMIT. check-in: 99b31a6b user: drh tags: wal-overwrite-frames
18:57
If it is known that checksums will be recalculated on transaction commit, skip calculating checksums when appending frames to the wal file. When recalculating checksums, recalculate them starting with the first overwritten frame - not the first frame in the transaction. check-in: 16b34f25 user: dan tags: wal-overwrite-frames
16:39
If a single page is written to the wal file more than once, have each subsequent copy overwrite the original frame. check-in: 5d113aef user: dan tags: wal-overwrite-frames

17:19

17:09
Small performance and size optimization spotted while working on the shared-cache problem. check-in: 828958ff user: drh tags: trunk

Add some assert() statements to verify, where possible, that BtShared.db is set correctly. Closed-Leaf check-in: 359277e0 user: dan tags: shared-cache-fix
16:06
Have the vdbe layer call sqlite3BtreeEnter() on all b-trees in use from within sqlite3VdbeExec() even in SQLITE_THREADSAFE=0 builds. This ensures that BtShared.db is set correctly. check-in: d0214602 user: dan tags: shared-cache-fix
02:06
Add the "sqlite3 -sourceid" command in the TCL interface. Use that command and others to output additional information about the test configuration at the conclusion of a TCL test. check-in: 4f80440b user: drh tags: trunk
2016-01-06
15:54
Disable the --limit-mem option on fuzzcheck unless the SQLITE_ENABLE_MEMSYS5 or SQLITE_ENABLE_MEMSYS3 compile-time options are used. check-in: 55a11fd6 user: drh tags: trunk
11:01
Version 3.10.0 check-in: fd0a50f0 user: drh tags: trunk, release, version-3.10.0
2016-01-05
03:39
Always use -DSQLITE_ENABLE_MEMSYS5 for fuzzcheck so that the --limit-mem option will work. check-in: a8556977 user: drh tags: trunk
03:39
Another attempt to get reuse of excess opcode array space working correctly on all architectures and platforms. check-in: 2f858374 user: drh tags: trunk

13:06
Fix the conflict2.test module which was broken by check-in [e30062e9f6c]. check-in: b779ca8a user: drh tags: trunk
12:07
A new approach to very large sqlite3_mprintf() strings: Back out the [d655a665] check-in and instead make the size fields in StrAccum unsigned. Strings generated by sqlite3_mprintf() can now be as large as 2^31-1 bytes. check-in: 7adb789f user: drh tags: trunk
04:44
Improved comment on the vtabH-3.1 test. check-in: 22abe080 user: drh tags: trunk

16:26
Avoid misaligned memory allocations on Sparc in sqlite3VdbeMakeReady(). This fixes a problem introduced by check-in [a9e819082b]. check-in: a304e346 user: drh tags: trunk

Enhance the command-line shell so that it can handle MBCS characters on input and output. check-in: 3d81dfe3 user: drh tags: trunk
16:51
Changes to the way that the default BINARY collating sequence is recorded result in a slightly smaller and slightly faster executable. More work could be done to make this cleaner. check-in: 2081d757 user: drh tags: trunk
15:18
Simplification to the xfer-optimization logic. check-in: f35ba018 user: drh tags: trunk
14:06

2015-12-23
16:42
Fix some harmless gcc compiler warnings. Mostly in fts5, but also two in the core code. check-in: 5d44d4a6 user: dan tags: trunk
10:54
Enhance the 'utc' modifier on date/time functions so that if the LHS is already known to be in UTC, the modifier becomes a no-op. This is not an incompatibility because the behavior is documented as "undefined" in that scenario. check-in: b910a3d5 user: drh tags: trunk
2015-12-21
15:22
Ensure that the Expr objects that describe indexed expressions are not modified by code generation. Fix for an assert() problem found by Jon Metzman using AFL. check-in: 34073ce8 user: drh tags: trunk

14:59
Add a new assert() statement to the snapshot-specific part of sqlite3WalBeginReadTrans(). check-in: d8a12023 user: dan tags: trunk
13:51
Simplified alignment constraints in the memory reuse logic of sqlite3VdbeMakeReady(). check-in: e998513e user: drh tags: trunk
12:44
Add the experimental snapshot interface. Because it is experimental, it is subject to change or removal at a later date. check-in: 9b124a5a user: drh tags: trunk
04:11
Fix a memory allocation bug introduced last week by check-in [a9e819082ba]. The bug only appears on systems where the size of a structure is not always a multiple of 8 - which in practice means only on 32-bit windows systems. check-in: 96d3e99f user: drh tags: trunk
03:27
Mention that the snapshot interfaces are only available if SQLite is compiled with SQLITE_ENABLE_SNAPSHOT. Closed-Leaf check-in: 843c15a5 user: drh tags: snapshot-get

20:03
Update the sqlite3_snapshot_get() API so that if the caller does not have an open read transaction on the named database, one is automatically opened. check-in: b9c90f10 user: dan tags: snapshot-get
19:44
Add tests to snapshot.test. check-in: f3b74362 user: dan tags: snapshot-get
19:11
Return SQLITE_BUSY (not SQLITE_BUSY_SNAPSHOT) if sqlite3_snapshot_open() fails to obtain the shared checkpointer lock. check-in: 5343060b user: dan tags: snapshot-get
18:06
Add tests to ensure that an sqlite3_snapshot_open() client cannot be tricked into reading a corrupt snapshot even if another process fails mid-checkpoint. check-in: b908048b user: dan tags: snapshot-get
17:59
Move pointer range comparisons into a macro, where they can be dealt with in a more portable way. check-in: 05bc4f92 user: drh tags: trunk

17:23
Further simplifications to the VDBE code generation logic that flow out of the previous check-in. check-in: 6a5dfe85 user: drh tags: trunk
16:26
Simplification of the DROP TRIGGER logic using sqlite3NestedParse() instead of hand-coded VDBE code. This is a manual cherry-pick of the key change from check-in [c80bbf14b365d]. check-in: 8021b4c8 user: drh tags: trunk
16:04
Merge unrelated fixes from trunk. check-in: 362615b4 user: drh tags: snapshot-get
2015-12-08

16:08
Avoid doing comparisons with pointers that might have been previously been passed to realloc() and/or free(). check-in: f20396ad user: drh tags: trunk
04:18
Add a test case of the form "WHERE a<2 OR a<3" using PRAGMA count_changes. This test case was failing before the 3.9.0 release. check-in: 177862c1 user: drh tags: trunk
