| 20:03 | Add the SQLITE_FCNTL_TRACE file control and generate it for OP_Trace when compiled with SQLITE_USE_FCNTL_TRACE. Update vfslog.c to make use of the new file control. Also update vfslog.c to log UNLOCK events before the fact, rather than afterwards. check-in: e801f35a user: drh tags: trunk | |
