| 11:09 | Follow-up to [0bf0fd242b93c3bd30]: only reset the pager when adding a new codec, not when overwriting an existing codec. Also, improve a comment in the pcache1 subsystem. (check-in: 5c040fdb user: drh tags: trunk) | |

| 13:51 | On the first connection to a WAL-mode database that was not cleanly shut down and contains a left-over -shm file, truncate the -shm file to 3 bytes instead of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file. Such a rogue process might think it is being helpful by cleaning up old files, but there is a race condition that can cause damage to the database. (check-in: 90cf32cd user: drh tags: trunk) | |
