19:35
Add the xPhraseFirstColumn() and xPhraseNextColumn() API functions to fts5. For iterating through the set of columns that contain intances of a phrase. (check-in: 8c30605b user: dan tags: fts5-offsets)
2015-12-28
19:55
Change the name of the offsets=0 option to "detail=column". Have the xInst, xPhraseFirst and other API functions work by parsing the original text for detail=column tables. (check-in: 228b4d10 user: dan tags: fts5-offsets)
2015-12-24
14:53
Avoid a harmless compiler warning on systems where the byteorder cannot be determined at compile-time. (check-in: 7c7b7f26 user: drh tags: trunk)
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)
2015-12-22
18:54
Updates so that fts5 API functions xInst, xPhraseFirst and xPhraseNext work with the offsets=0 option. (check-in: 69bffc16 user: dan tags: fts5-offsets)
2015-12-21
18:45

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)
2015-12-18
19:07
Fix a problem with prefix queries on fts5 offsets=0 tables. (check-in: ad0987d8 user: dan tags: fts5-offsets)

2015-12-17
20:36
Add the "offsets=0" option to fts5, to create a smaller index without term offset information. A few things are currently broken on this branch. (check-in: 40b5bbf0 user: dan tags: fts5-offsets)
19:17
Make the VdbeCursor object even smaller. But the resulting library is bigger and slower than trunk. This branch is a failed experiment. (Leaf check-in: 896a06cc user: drh tags: optimize-vdbecursor)
17:30
Reduce the size of the VdbeCursor object by a pointer (the pBt pointer used for ephemeral tables). (check-in: 98b710c3 user: drh tags: optimize-vdbecursor)
14:18
Fix the spellfix1_scriptcode() function to ignore whitespace and punctuation, and to recognize hebrew and arabic scripts. (check-in: 7adfa4a5 user: drh tags: trunk)
13:28
Fixes for harmless compiler warnings. (check-in: 85ebd46c user: drh tags: trunk)

Add a new assert() statement to the snapshot-specific part of sqlite3WalBeginReadTrans(). (check-in: d8a12023 user: dan tags: trunk)
13:59
Merge recent changes from trunk. Also remove unused variables to permit compiling with -Werror. (check-in: 57b700ba user: drh tags: onepass-delete-or)
13:51
Simplified alignment constraints in the memory reuse logic of sqlite3VdbeMakeReady(). (check-in: e998513e user: drh tags: trunk)
12:53
Merge recent trunk enhancements, and in particular the snapshot interface. (check-in: 7e7b2406 user: drh tags: apple-osx)

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)

19:44
Add tests to snapshot.test. (check-in: f3b74362 user: dan tags: snapshot-get)

2015-12-09
20:05
Update sqlite3_snapshot_open() to reduce the chances of reading a corrupt snapshot created by a checkpointer process exiting unexpectedly. (check-in: 7315f7cb user: dan tags: snapshot-get)

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)

16:58
Changes to avoid undefined behavior in memset() and memcpy() and in the comparisons of pointers from different allocations. All problems are found by analysis tools - none have been seen in the wild. (check-in: 901d0b8f user: drh tags: trunk)
16:08
