2019-01-09
21:12
Fix an out-of-bounds read in SQL function fts5_decode() that could occur if it was passed a corrupt record. (check-in: 931278b257 user: dan tags: trunk)

16:52
Fix another potential buffer overread in fts5. (check-in: d0e943d957 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: 6281ef974c 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: 6064584d57 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: 598d7358e7 user: drh tags: trunk)
07:17
Fix two more problems with corrupt database handling in fts5. (check-in: 444c7c99be user: dan tags: trunk)
2019-01-04

13:59

2018-12-31
21:43
Fix harmless compiler warnings. (check-in: b57c545a38 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: e130319317 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Remove an optimization that can no longer occur, being superceded by the subquery-reuse optimization.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: 4fcdc7a293 user: drh tags: reuse-subqueries)
18:30
Merge enhancements and bug fixes from trunk. (check-in: 9fb646f29c user: drh tags: reuse-subqueries)
17:58
Small changes to the OP_OpenEphemeral opcode to improve testability. (check-in: f856676c84 user: drh tags: trunk)
16:36
Fix the OP_OpenEphemeral opcode in the bytecode engine so that if it is called a second or subsequent time, it merely clears the existing table rather than creating a new one. Proposed fix for ticket [d0866b26f83e9c55e30de0821f5d]. (check-in: 4678cb1044 user: drh tags: trunk)
2018-12-29
14:23
Additional small performance increase and size reduction to the sqlite3VdbeMakeLabel() mechanism. (check-in: 1bdee199a7 user: drh tags: trunk)
02:26
A new implementation of sqlite3VdbeMakeLabel() is faster and makes fewer memory allocations by deferring memory allocation until sqlite3VdbeResolveLabel() is called, at which point the code generator has a better idea of how big the relocation table needs to be. The sqlite3VdbeMakeLabel() routine now takes a Parse* parameter instead of Vdbe*. (check-in: 4a0929ac76 user: drh tags: trunk)
2018-12-28
21:32
Merge performance enhancements from trunk. (check-in: 0f1b9ff9e1 user: drh tags: reuse-subqueries)

Faster allocation of new sqlite3_stmt objects. (check-in: 891f1f7218 user: drh tags: trunk)
20:14
Move the nOpAlloc field from Parse into Vdbe to avoid an extra pointer deference on the fast path in sqlite3VdbeAddOp3(). (check-in: 8f10efc29d user: drh tags: trunk)
19:23
Merge patches and enhancements from trunk. (check-in: da53f3d3ff user: drh tags: reuse-subqueries)

Fix another problem with loading the structure record from a corrupt fts5 database. (check-in: c4d44542d2 user: dan tags: trunk)
17:45

14:33
Avoid an undefined left-shift operation in fts5 caused by malformed utf-8 text. (check-in: c3a3a11194 user: dan tags: trunk)
13:57
Fix a buffer overwrite in fts5 triggered by a corrupt database. (check-in: a385298df2 user: dan tags: trunk)

Fix another problem in fts5 caused by a corrupt schema record. (check-in: ff45f9dd69 user: dan tags: trunk)

07:46
Fix a null-pointer dereference that could occur in fts5 with a corrupt database. (check-in: b0a49d5e6d user: dan tags: trunk)
02:16
Fix a problem in which nested CTEs with the same table name trick the code generator into thinking they are the same CTE, which then tries to use the manifest them both into the same transient table. (check-in: 202dd03301 user: drh tags: trunk)
00:30
In the treeview debugging output, provide additional details for the Table object associated with each FROM clause term. (check-in: 11d4682d2e user: drh tags: trunk)
2018-12-26
18:34
Update the coverage-wal permutation to cover branches enabled by SQLITE_ENABLE_SNAPSHOT. (check-in: 6821c61f1d user: dan tags: trunk)
17:49
Add a few more test cases to walvfs.test. (check-in: 14a64df36e user: dan tags: trunk)

Fix a typo in a comment that is used to generate session documentation. (check-in: a1f50d57ce user: drh tags: trunk)
00:15
Increase the number of parameters to sqlite3WhereCodeOneLoopStart() to encourage the compiler to inline that routine within sqlite3WhereBegin(). This gives a performance improvement. (check-in: 3c2ad0e915 user: drh tags: reuse-subqueries)
2018-12-24
20:21
Improvements to EXPLAIN QUERY PLAN formatting. The MULTI-INDEX OR now shows a separate "INDEX" subtree for each index. SCALAR SUBQUERY entries provide a subquery number that is related back to the .selecttrace output. (check-in: 7153552bac user: drh tags: reuse-subqueries)
20:00
Add a few more test cases to walfault2.test and walvfs.test. (check-in: 3873941c4f user: dan tags: trunk)
