| 22:42 | Add support for the 'lsm1.c' target in the MSVC makefile. check-in: 6de21dea user: mistachkin tags: trunk | |

| 20:02 | New result code SQLITE_READONLY_DIRECTORY is returned when an attempt is made to write on a database file that is in a read-only directory and hence the journal file could not be created. This situation formerly returned SQLITE_CANTOPEN, which less helpful. check-in: 3ec73c38 user: drh tags: trunk | |
