| 21:05 | Merge all recent trunk enhancements into the apple-osx branch. (check-in: 53b14a38 user: drh tags: apple-osx) | |
| 19:38 | • Ticket [b9f01010] Violation of the Query Planner Stability Guarantee status still Open with 6 other changes (artifact: ecf53365 user: drh) | |
| 19:21 | • New ticket [b9f01010]. (artifact: 81c613f2 user: drh) | |
| 15:47 | • Edit [e4a022be4b069b08|e4a022be]: Mark "Closed". (artifact: 85d116ac user: dan) | |
| 15:47 | When generating individual loops for each ORed term of an OR scan, move any constant WHERE expressions outside of the loop, as is done for top-level loops. (check-in: 712267c9 user: dan tags: trunk) | |

| 16:48 | Update the sqldiff utility so that if the --vtab switch is specified "rtree", "fts3", "fts4" and "fts5" tables are diff'd directly and the underlying real database tables ignored. Without this switch, all virtual tables are ignored and the diff is performed on the underlying real tables. (check-in: b8671e94 user: dan tags: trunk) | |
| 12:35 | Fix the build for -DSQLITE_OMIT_VIRTUALTABLE (check-in: 91113142 user: drh tags: trunk) | |

| 23:31 | Mark some branches as unreachable after the recent change that recognizes mismatch result set sizes on compound SELECT statements sooner. (check-in: c8d1f305 user: drh tags: trunk) | |
| 21:35 | Testability improvement. (Closed-Leaf check-in: eed6a331 user: drh tags: btree-opt2) | |
| 18:47 | Improve test coverage of fts5. (check-in: df5ccea8 user: dan tags: fts5) | |
| 18:24 | Multiple overflow cells are always adjacent and sequential. Exploit this invariant for a small size reduction and performance increase and add assert()s to prove the invariant. (check-in: f77f2f48 user: drh tags: btree-opt2) | |
| 17:09 | Faster loading of cell pointers into the b.apCell array in balance_nonroot. (check-in: fda89b05 user: drh tags: btree-opt2) | |
| 16:00 | Avoid unnecessary cachedCellSize() calls in the cell partition adjustment phase of balance_nonroot(). (check-in: 6319ee12 user: drh tags: btree-opt2) | |
| 15:36 | Change pageInsertArray() and pageFreeArray() so that they use the CellArray object and compute cell sizes as needed, resulting in smaller and faster code. (check-in: f7f41818 user: drh tags: btree-opt2) | |
| 15:06 | Merge latest trunk changes with this branch. Add tests for columnsize=0. (check-in: ef44c71a user: dan tags: fts5) | |
| 14:49 | Improvements to the way balance_nonroot() constructs the b.apCell array of pointers to cells. (check-in: ee44bb25 user: drh tags: btree-opt2) | |
| 13:02 | Merge the compound SELECT operator fix from trunk. (check-in: a7be554f user: drh tags: btree-opt2) | |
| 12:19 | Test that the left and right sides of a compound SELECT operator have the same number of expressions in the expanded expression list before beginning to generate code. (check-in: 4df852ce user: dan tags: trunk) | |
| 02:37 | Avoid computing cell sizes in balance_nonroot() until they are really needed. This gives an overall 1.7% performance gain for about 1000 extra bytes of code space. (check-in: 43844537 user: drh tags: btree-opt2) | |

| 22:00 | Fix and/or improve comments in wal.c. No code changes. (check-in: ee9991be user: drh tags: trunk) | |
| 19:27 | Add test case for SQLITE_FULL errors to pagerfault.test. Remove a NEVER macro in pager.c that this hits. (check-in: 3e9680c4 user: dan tags: trunk) | |
| 17:59 | Include the SOURCE_ID value in the log messages output for corruption, misuse, and CANTOPEN errors. (check-in: 1727a81f user: drh tags: trunk) | |
| 17:58 | Adjust the shared-memory locking range to account for the new version number values in the wal-index header. (check-in: a6dc0df3 user: drh tags: trunk) | |
| 15:55 | Add a version number to the wal-index header. If SQLite encounters a version number in either the wal or wal-index files that it does not understand, the operation is abandoned and SQLITE_CANTOPEN returned. (check-in: 8d0f8a7f user: dan tags: trunk) | |
| 15:18 | Fix the xCurrentTimeInt64 interface on windows. It was off by a factor of 10. (check-in: 51ef43b9 user: drh tags: trunk) | |
| 15:04 | Simplifications to the pager_delmaster() implementation. (check-in: 8bfbdec6 user: drh tags: trunk) | |
