| 14:03 | The sqlite3_snapshot_describe() interface useful for debugging snapshot logic. Leaf check-in: 3fbfa9a8 user: drh tags: sqlite3_snapshot_describe | |
| 10:24 | Fix a bug in tool/mksourceid.c: The mksourceid.c program was incorrectly including the "# Remove this line" line of the Fossil-generated "manifest" file in the SHA3 hash. That means that all SQLITE_SOURCE_IDs for trunk versions going back to check-in [30966d56] (2017-08-22) are incorrect. check-in: 65765222 user: drh tags: trunk | |
