| 17:24 | Fix a faulty assert() in the WAL-mode logic for read-only shared memory. (check-in: a13cfe61 user: drh tags: trunk) | |
| 15:48 | Add a missing check for out-of-memory in the lemon code generator. (check-in: efb20b9d user: drh tags: trunk) | |
| 13:04 | Merge the read-only shared memory branch into trunk. After this merge, an unprivileged process can open WAL-mode databases owned by another user as long as a database connection with write permission exists on the database file and if the readonly_shm=1 URI query parameter is supplied.
