| 02:02 | Enhance the ALTER TABLE RENAME COLUMN feature so that it works on tables that have redundant UNIQUE and/or PRIMARY KEY constraints. Fix for ticket [bc8d94f0fbd633fd9a051e3] (check-in: f09aa3248e user: drh 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) | |

| 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) | |
| 01:46 | Give symbolic names to the special prepared statements used to implement incremental blob I/O. (Leaf check-in: 2a1cc6327a user: drh tags: named-blob-I/O) | |

| 21:56 | Add the exprNodeCopy() routine that will safely memcpy() an Expr node that might be a size-reduced node. (check-in: a874c64996 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) | |

| 23:39 | Give a meaningful error on an attempt to use UPSERT on a virtual table, rather than simply not working. (check-in: fa98748f95 user: drh tags: trunk) | |
| 19:39 | Fix the experimental sqlite3_wal_info() API so that it works with wal2 mode. (check-in: 079daedbe4 user: dan tags: begin-concurrent-pnu-wal2) | |
| 19:25 | Add the "-external" option to the tserver_test.tcl program.. (check-in: ae7c5ed15d user: dan tags: begin-concurrent-pnu-wal2) | |
| 17:12 | Update the "tserver" program to report the amount of time spent in COMMIT commands. (check-in: cf494b412c user: dan tags: begin-concurrent-pnu-wal2) | |
| 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: d7f55c62c3 user: drh tags: trunk) | |
| 12:46 | Remove debugging pragmas accidently left in by a prior change. (check-in: 26275fc7e8 user: drh tags: trunk) | |

|

| 19:12 | Fix some problems with sqlite3_interrupt() handling in fts5. (check-in: c0eb839a3c user: dan tags: trunk) | |
| 16:03 | Fix the csv01.test module so that it works on systems with \r\n line endings. (check-in: 36eaf5a5e5 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: df939c89fa user: drh tags: trunk) | |
| 15:22 | Fix a harmless compiler warning in the CSV extension. (check-in: fbcd72565f user: drh tags: trunk) | |

| 23:49 | Fix harmless compiler warnings in the unicode2 logic of FTS3 and FTS5. (check-in: 703029ac6d user: drh tags: trunk) | |
| 19:46 | Merge changes from begin-concurrent-wal2. Also modify the unix-excl shm-locks on this branch so that it is not an error to attempt to release an EXCLUSIVE lock that is not held. (check-in: 86685679b4 user: dan tags: begin-concurrent-pnu-wal2) | |
| 17:08 | 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: fcb7348ba1 user: dan tags: begin-concurrent-wal2) | |
| 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: 8445fb6d5d user: dan tags: wal2) | |
| 16:30 | Merge latest wal2 changes into this branch. (check-in: c31eeb3c87 user: dan tags: begin-concurrent-wal2) | |

| 19:17 | Fix another fts5 problem caused by a corrupt database. (check-in: 911342f751 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: 5c188361a9 user: dan tags: trunk) | |
| 13:59 | Fix another case in fts5 where a corrupt database could cause a buffer overread. (check-in: f7e6cdc562 user: dan tags: trunk) | |

| 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) | |

| 15:04 | Here is the beginnings of an effort to factor out the implementation of scalar subqueries to be implemented as subroutines at the end of the main body of bytecode, after the jump back to the OP_Init opcode. This is an incremental check-in that contains only preliminary changes. (check-in: 50e5f390fb user: drh tags: factor-out-scalar-subselect) | |
|
2018-12-25
| ||
| 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) | |
| 14:30 | Restore a line of code that was previously commented out for debugging. (check-in: e53781f5bd user: drh tags: reuse-subqueries) | |
