18:44 | Remove an unnecessary column-cache flush operation. Add code to trace the column cache when compiled with SQLITE_DEBUG and using PRAGMA vdbe_addoptrace=ON. (check-in: 58704ed1 user: drh tags: trunk) | |
16:27 | Remove an unnecessary column-cache flush. Add another test case to the speedtest1.c program to accentuate the benefit of not flushing the cache at that point. (Closed-Leaf check-in: 97fdfc6b user: drh tags: column-cache-debug) | |
