00:56 | Fix a compiler warning associated with USE_PREAD64. (check-in: c299e55a66 user: drh tags: trunk) | |
00:49 | Fix over-length source code lines in os_unix.c. (check-in: 7560a9fa50 user: drh tags: trunk) | |
00:19 | Keep track of the optimal number of reserved bytes (by looking at reserve byte requests in calls to sqlite3BtreeSetPageSize()) and then change the reserve byte count to the optimal when doing a VACUUM or when using the backup API. (check-in: 28c2b72628 user: drh tags: trunk) | |
