| 19:19 | Check in the instrumented code for the mptest test case that appears to show a spontaneously disappearing journal file. (Closed-Leaf check-in: 96f04d99f3 user: dan tags: missing-journal-file) | |
| 16:19 | Add extra #ifndef statements in os_unix.c and os_win.c to make sure the memory mapped I/O really is disabled when SQLITE_DISABLE_MMAP is set. (check-in: c1e2523c90 user: drh tags: trunk) | |

| 20:47 | Disable the use of memory-mapped I/O if the SQLITE_DISABLE_MMAP macro is defined. Automatically define this macro for OpenBSD and QNX. Other systems are likely to be added to the disabled list over time. (check-in: 8a4314a398 user: drh tags: trunk) | |
| 19:13 | In mptester, handle startScript no-change commits using a retry rather than grabbing an exclusive transaction. (check-in: ae8bb24bfb user: drh tags: trunk) | |
