| 20:57 | Add experimental mode that uses two wal files. Activated using "PRAGMA journal_mode = wal2". (check-in: e2fc5c814c user: dan tags: wal2) | |
| 18:26 | Updates to requirements marks. (check-in: 40964a4ef7 user: drh tags: trunk) | |
| 17:05 | Update the speedtest1 program so that it prints the output of "PRAGMA compile_options" if the -stats option is specified. (check-in: 7c69f8f108 user: dan tags: trunk) | |
| 16:35 | Fix typos in session extension header comments. No changes to code. (check-in: 182ec9d6f6 user: mistachkin tags: trunk) | |
| 14:13 | New test cases for ticket [b899b6042f97f5] derived from a bug report on the mailing list from Wout Mertens. (check-in: ef94ea061d user: drh tags: trunk) | |
| 12:08 | Amend recent changes to busy.test to avoid failing with SQLITE_ENABLE_STAT4 builds. (check-in: 9ff4944194 user: dan tags: trunk) | |
| 12:06 | Turn restriction 20 on the query flattener into an assert since the situation restricted can no longer occur because of the more aggressive use of co-routines. (check-in: 4464f40ccd user: drh tags: trunk) | |
| 10:39 | Add tests to verify that the busy-handler is invoked correctly when processing "PRAGMA optimize" and ANALYZE commands. (check-in: fb83c3d8df user: dan tags: trunk) | |
| 05:59 | Remove a redundant restriction from the query flattener. (check-in: 66629b2a09 user: drh tags: trunk) | |
| 02:30 | Fix a minor typo in the query flattener header comment. No code changes. (check-in: d050dc605c user: drh tags: trunk) | |

| 12:20 | Fix a problem with the lempar.c parser template. (check-in: 3a9d802fda user: drh tags: trunk) | |
| 00:47 | Do not bother to initialize unused fields in the BtreePayload object. (check-in: b10d0f939c user: drh tags: trunk) | |

| ||
| 19:31 | Tweaks to documentation on sqlite3_open() and sqlite3_bind(). No code changes. (check-in: b8f7f19dc0 user: drh tags: trunk) | |
| 11:59 | Updates to documentation and requirements marks. No code changes. (check-in: 0f8102d71a user: drh tags: trunk) | |
| 10:22 | Add a test to show that the change on this branch is effective. (Closed-Leaf check-in: fc619be057 user: dan tags: stat4-avgeq) | |
| 00:07 | Avoid leaking Index.aiRowEst memory if an OOM causes a rollback which deletes the index before the aiRowEst deletion code in sqlite3AnalysisLoad() routine has a chance to run. Since the aiRowEst now might be deleted from freeIndex() which does not always have a db pointer, make sure the aiRowEst memory is not held in lookaside.

| 20:39 | Merge trunk changes. (check-in: c6ac80ed8d user: drh tags: index-scan-rate) | |
| 18:29 | Further refinements of the index scanning speed logic. (check-in: e5d9371da9 user: drh tags: index-scan-rate) | |
| 18:17 | If an "INSERT INTO ... SELECT" can use the xfer optimization, pass the OPFLAG_BULKCSR hint to btree cursors used to update indices. This results in a tighter key packing. (check-in: 087af29ee2 user: dan tags: trunk) | |
| 15:58 | Fix test cases so that they work when the query planner uses index size estimates to determine whether or not to try an covering index scan. (check-in: 2f394de88f user: drh tags: index-scan-rate) | |
| 15:30 | Improved estimates of the relative speed of index scans based on declared datatypes of columns in the table. Add "r" column to PRAGMA index_info, showing the estimated relative scan rate. (check-in: 07462bb605 user: drh tags: index-scan-rate) | |
| 02:36 | Progress toward using the iScanRatio information on indices. Many tests are still failing. (check-in: 6c352edbba user: drh tags: index-scan-rate) | |
| 00:07 | • Fixed ticket [a5c8ed66ca]: Incorrect count(*) when partial indices exist plus 5 other changes (artifact: ec7c3f4ce7 user: drh) | |
| 00:00 | Make sure the count(*) optimization works correctly even when partial indices are present. Ticket [a5c8ed66cae]. (check-in: 9f2f4c0a50 user: drh tags: trunk) | |
