Separate makefile targets for "dbfuzz2", "dbfuzz2-asan", and "dbfuzz2-msan". (check-in: ea119641 user: drh tags: trunk)

19:26
Fix a memory leak in fts5 that could occur if scalar function fts5_decode() was passed a corrupt record. (check-in: 240f1c0c user: dan tags: trunk)
18:35
Fix a memory leak in fts5. (check-in: ff3b011f user: dan tags: trunk)
17:08
Avoid use-after-free and double-free errors that could occur if an fts5 table is modified in certain ways while there are active cursors. (check-in: 3291b2a6 user: dan tags: trunk)

Fix further problems with fts5 handling corrupt databases. (check-in: 83c467d7 user: dan tags: trunk)

Fix the fts3DecodeIntArray() function so that it will not read off the end of the buffer it is handed. Any unread integers are set to zero. (check-in: 666cf8f6 user: drh tags: trunk)
2019-01-09
21:12

2019-01-07
16:52
Fix another potential buffer overread in fts5. (check-in: d0e943d9 user: dan tags: trunk)
15:57
For SQLITE_ENABLE_PREUPDATE_HOOK builds, disable the optimization for a REPLACE command on a WITHOUT ROWID table with no indexes, triggers or foreign key constraints that causes SQLite to clobber any existing row without separately checking for it. This optimization causes SQLite to omit the expected pre-update-hook callbacks. (check-in: 6281ef97 user: dan tags: trunk)
2019-01-06
02:06
The page size becomes fixed as soon as page1 from a non-empty database file is read. (check-in: 6064584d user: drh tags: trunk)

Give symbolic names to the special prepared statements used to implement incremental blob I/O. (Leaf check-in: 2a1cc632 user: drh tags: named-blob-I/O)
2019-01-05
21:56
Add the exprNodeCopy() routine that will safely memcpy() an Expr node that might be a size-reduced node. (check-in: a874c649 user: drh tags: trunk)
21:09
If the OP_ParseSchema opcode with a non-NULL P4 operand does not parse any rows out of the sqlite_master table, that indicates that the sqlite_master table is corrupt, so raise an SQLITE_CORRUPT error. (check-in: 598d7358 user: drh tags: trunk)
07:17
Fix two more problems with corrupt database handling in fts5. (check-in: 444c7c99 user: dan tags: trunk)
2019-01-04
23:39
Give a meaningful error on an attempt to use UPSERT on a virtual table, rather than simply not working. (check-in: fa98748f user: drh tags: trunk)
14:29
If the ".open" command fails in the CLI, reopen to :memory: so that at least some database is available for subsequent commands. (check-in: d7f55c62 user: drh tags: trunk)
12:46
Remove debugging pragmas accidently left in by a prior change. (check-in: 26275fc7 user: drh tags: trunk)
12:35
Fix a typo in a comment used to generate documentation. No functional changes. (check-in: ccc4f742 user: drh tags: trunk)
11:20
Fix another fts5 assert() that may fail if the database is corrupt. (check-in: 0888fc2e user: dan tags: trunk)
2019-01-03
19:12
Fix some problems with sqlite3_interrupt() handling in fts5. (check-in: c0eb839a user: dan tags: trunk)
16:03
Fix the csv01.test module so that it works on systems with \r\n line endings. (check-in: 36eaf5a5 user: drh tags: trunk)
16:00
Fix the shmlock.test script so that it works with the Windows restriction that UnlockFile must exactly correspond to a prior LockFile. (check-in: df939c89 user: drh tags: trunk)
15:22
Fix a harmless compiler warning in the CSV extension. (check-in: fbcd7256 user: drh tags: trunk)
15:17
Fix a problem with the second and subsequent sqlite3rbu_savestate() calls made on an RBU vacuum handle. (check-in: bef216df user: dan tags: trunk)
00:44
Fix the geopoly_svg() function so that it returns NULL when given zero arguments. (check-in: 120cb176 user: drh tags: trunk)
2019-01-02
23:49
Fix harmless compiler warnings in the unicode2 logic of FTS3 and FTS5. (check-in: 703029ac user: drh tags: trunk)
17:00
Reinstate assert() statements in os_unix.c that were removed to allow wal-mode SHARED locks to be taken over more than one locking slot (this branch no longer does that, so the assert() statements can go back in). (check-in: 8445fb6d user: dan tags: wal2)
16:15
Merge latest trunk changes into this branch. (check-in: 87ef68f9 user: dan tags: wal2)
16:01
Add another test case to vacuum-into.test. (check-in: 0465d2fc user: dan tags: trunk)
15:27
Add test cases for commit [6c6fb1c6]. (check-in: 3961995c user: dan tags: trunk)
14:34
Raise an error if the argument to VACUUM INTO is an identifier. (check-in: 6c6fb1c6 user: drh tags: trunk)
2019-01-01
19:17
Fix another fts5 problem caused by a corrupt database. (check-in: 911342f7 user: dan tags: trunk)
18:00
Ensure that when a new cursor is opened by OP_OpenDup, any existing cursor with the same id opened by a previous OP_OpenDup is closed first. (check-in: 5c188361 user: dan tags: trunk)
13:59
Fix another case in fts5 where a corrupt database could cause a buffer overread. (check-in: f7e6cdc5 user: dan tags: trunk)
2018-12-31
21:43
Fix harmless compiler warnings. (check-in: b57c545a user: drh tags: trunk)
20:39
Additional steps to help ensure that scalar subqueries are only evaluated once even if they are used in multiple places within the query. This fixes a performance regression reported on the mailing list and caused by check-in [531eca6104e41e43] which was a fix for ticket [787fa716be3a7f650c]. Think of this check-in as an improved fix for that ticket. (check-in: e1303193 user: drh tags: trunk)
20:13
Remove an optimization that can no longer occur, being superceded by the subquery-reuse optimization. Put an assert in place of the optimization to detect if the need for this optimization ever returns. (Closed-Leaf check-in: 4fcdc7a2 user: drh tags: reuse-subqueries)
18:30
Merge enhancements and bug fixes from trunk. (check-in: 9fb646f2 user: drh tags: reuse-subqueries)
