| 20:03 | Update the sqlite3_snapshot_get() API so that if the caller does not have an open read transaction on the named database, one is automatically opened. (check-in: b9c90f10 user: dan tags: snapshot-get) | |
| 19:44 | Add tests to snapshot.test. (check-in: f3b74362 user: dan tags: snapshot-get) | |
| 19:11 | Return SQLITE_BUSY (not SQLITE_BUSY_SNAPSHOT) if sqlite3_snapshot_open() fails to obtain the shared checkpointer lock. (check-in: 5343060b user: dan tags: snapshot-get) | |
