| 02:08 | Fix a (harmless) off-by-one error in the unix VFS logic that fsync()s a directory after deleting a file. (check-in: 3d02711a user: drh tags: trunk) | |
| 01:04 | Simplification of the logic used to take the process-wide lock in the unix-excl VFS. (check-in: 73defd52 user: drh tags: trunk) | |
| 00:05 | Remove all traces of SQLITE_FCNTL_WAL_BLOCK from the unix VFS - that feature had been disabled for a long time and never actually worked. (check-in: e1d5320c user: drh tags: trunk) | |
