| 15:59 | Add an English language error message to corresponding to SQLITE_PROTOCOL. "locking protocol". check-in: ca327e32 user: dan tags: trunk | |
| 12:22 | Add test for the code that detects an inconsistent pair of wal-index headers to wal2.test. check-in: 157feba1 user: dan tags: trunk | |
| 11:56 | If an attempt to sync the database file as part of a checkpoint fails, do not update the shared "nBackfill" variable. Otherwise, another process could wrap the log and overwrite content before it is synced into the database. check-in: b813233d user: dan tags: trunk | |
