Performance improvement on the instr() function, especially for large haystacks. check-in: ce51f1a2 user: drh tags: trunk

Fix a possible memory leak when trying to UPDATE a corrupt RTREE index. check-in: 63eb803d user: drh tags: trunk

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

The page size becomes fixed as soon as page1 from a non-empty database file is read. check-in: 6064584d user: drh tags: trunk

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

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

Fix a typo in a comment used to generate documentation. No functional changes. check-in: ccc4f742 user: drh tags: trunk

Fix some problems with sqlite3_interrupt() handling in fts5. check-in: c0eb839a user: dan tags: trunk

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

Fix the geopoly_svg() function so that it returns NULL when given zero arguments. check-in: 120cb176 user: drh tags: trunk
