| 16:51 | While PRAGMA full_column_names is off (the default) do not make changes to the short_column_names pragma when computing the column names for subqueries. (Leaf check-in: 718ead555b user: drh tags: literal-column-names) | |
| 16:27 | Fix a problem with running ALTER TABLE on a schema that contains expressions of the type "col IN ()" (empty set on RHS of IN operator). (check-in: 2d9cd06715 user: dan tags: trunk) | |

| 20:42 | When unpacking a sorter record, do so from right to left instead of left to right, since by starting with the right-most column, the work done by OP_Column opcodes is reduced. (check-in: 8055e4f424 user: drh tags: trunk) | |
| 18:28 | Reorganize spellfix.c to make it easier to edit automatically (e.g. using a script). No changes to functionality. (check-in: 090a64faaa user: dan tags: trunk) | |
| 16:04 | Rearrange fields of the BtCursor object so that it is smaller and requires less initialization, for a small performance improvement. (check-in: 0ddf5292cc user: drh tags: trunk) | |
| 15:07 | Add the normalize.c extension. (check-in: 16ebe558d2 user: drh tags: trunk) | |

| 14:58 | • Edit [cbec1bfe4b9f0e9f|cbec1bfe4b]: Mark "Closed". (artifact: e02af0b9b4 user: drh) | |
| 14:40 | Interchange the numeric codes for CURSOR_VALID and CURSOR_INVALID to obtain a small size decrease and performance increase. (check-in: e0f192ea6d user: drh tags: trunk) | |
| 14:39 | Adjust the fts3rank.test module so that it works on big-endian systems (hopefully - I don't have a big-endian machine to test the change on.) (check-in: e4766cabdf user: drh tags: trunk) | |
| 13:15 | Improved error message output when the btreeinfo.c extension is run in a connection that lacks sqlite_dbpage support. (check-in: 461b0b81b2 user: drh tags: trunk) | |

| 11:25 | Fix the sqlite3ext.h header file so that it correctly accesses the new sqlite3_value_nochange() and sqlite3_vtab_collation() interfaces. (check-in: 6185d190e2 user: drh tags: trunk) | |
| 06:30 | Update a couple of test scripts so that they work on F2FS file-systems that support atomic transactions. (check-in: 49e58e645e user: dan tags: trunk) | |
| 01:58 | Make the shell functional even if compiled with SQLITE_OMIT_COMPLETE. Omit the sqlite3_complete() call from the fuzzing interface if it is compiled with SQLITE_OMIT_COMPLETE. (check-in: c3e816cca4 user: drh tags: trunk) | |
| 01:02 | Invoke the sqlite3_complete() interface from the fuzzer. (check-in: 332bf84625 user: drh tags: trunk) | |

| 16:07 | • Edit [8063197ef141c0c6|8063197ef1]: Change branch background color to "#b0b28e". (artifact: 10ecfdd8bd user: drh) | |
| 16:00 | Ensure that if a deferred FK constraint is violated by a statement that creates its own implicit transaction, the statement is not an "active-write" after sqlite3_step() returns. (Closed-Leaf check-in: 8063197ef1 user: dan tags: deferred-fk-quirk) | |
| 15:11 | Change the cost estimator in the query planner to take into account the logN rowid lookup cost when going from an index to a table. (check-in: b442525b0b user: drh tags: stat2-enhancement) | |
