| 20:33 | Update RBU so that it supports indexes on expressions. (check-in: 6bfa44da user: dan tags: trunk) | |

| 23:54 | Add a test case demonstrating the collation problem with constant propagation. (check-in: 50add839 user: drh tags: propagate-const-opt) | |
| 23:47 | Generalize the constant propagation optimization so that it applies on every WHERE close, not just those that contain a subquery. This then demonstrates that the current implementation is inadequate since it does not take into account collating sequences. (check-in: 57eb2abd user: drh tags: propagate-const-opt) | |
| 21:48 | In the unix VFS, give every unixInodeInfo object its own mutex, rather than using the global VFS mutex, to improve concurrency in cases where there are many threads operating on separate database files. (check-in: 22f47cf4 user: drh tags: trunk) | |
| 21:16 | Initial implementation of the WHERE-clause constant propagation optimization. (check-in: 2fb82ad8 user: drh tags: propagate-const-opt) | |

| ||
| 19:59 | Add the new sqlite3.mDbFlags field. Factor out bits of sqlite3.flags that do not interact with PRAGMA statements into sqlite3.mDbFlags. (check-in: 3808a00f user: drh tags: trunk) | |
| 18:26 | Allow ATTACH and DETACH to occur inside of a transaction. (Closed-Leaf check-in: ac1fd6be user: drh tags: attach-in-trans) | |
| 10:04 | Fix a comment on the UnpackedRecord.r1 and UnpackedRecord.r2 fields. No changes to code. (check-in: 622b1089 user: drh tags: trunk) | |

| 18:06 | Fix where.c handling of "IN (SELECT ...)" expressions when the SELECT returns more than one result column. Also error handling for other row value constructor cases. (check-in: 061b8006 user: dan tags: rowvalue) | |
| 15:17 | Merge fixes to sqlite3_scrub_backup() from trunk. (check-in: 91e811f5 user: drh tags: apple-osx) | |
| 10:46 | Ensure that the sqlite3_scrub_backup() extension creates a backup database at least as large as indicated by the database header, even if the last page of the input database is a free-list leaf. (check-in: 483994a5 user: dan tags: trunk) | |
| 04:54 | Merge the cache_spill VACUUM fix from trunk. (check-in: cc6bfdf8 user: drh tags: apple-osx) | |
| 04:49 | Copy the cache_spill setting from the main database over to the vacuum_db transient database when running a VACUUM. (check-in: c0e7d98e user: drh tags: trunk) | |
| 04:31 | Make sure affinity is applied correctly on lower-bound range constraints in the min() optimization. Fix for ticket [a0bac8b3c3d1bb]. (check-in: b819bace user: drh tags: trunk) | |
| 04:24 | • Fixed ticket [a0bac8b3]: CREATE INDEX changes the answer plus 3 other changes (artifact: 17eb1530 user: drh) | |
| 04:23 | Make sure affinity is applied correctly on lower-bound range constraints in the min() optimization. Fix for ticket [a0bac8b3c3d1bb]. (check-in: 0e9f534f user: drh tags: apple-osx) | |
| 04:21 | • Ticket [a0bac8b3] CREATE INDEX changes the answer status still Open with 6 other changes (artifact: af44096d user: drh) | |
