| 13:14 | Rework automatically acquired OPFS locks to be released during idle time. This eliminates the performance hit reported in [46304ba057707c]. (Closed-Leaf check-in: a7fe91af user: stephan tags: opfs-lock-without-xlock) | |
| 11:35 | OPFS: if an op which needs a lock is called when no lock has been obtained, automatically lock it at the start of the op and unlock it at the end of that op. This is an attempt to alleviate the cross-tab contention described in forum post 58a377083cd24a but it increases speedtest1 run time by approximately 4x. Perhaps auto-lock can be combined with the older idle-time-based auto-unlock to unlock such locks (but not those from xLock()) to improve this?

This problem appears to go all the way back to the beginning of the push-down optimization in check-in 6df18e949d367629 in SQLite 3.8.11. (check-in: ed14863d user: dan tags: trunk) | |

| 21:08 | This experimental branch attempts to use columns for an index-on-expression in place of the expression that is being indexed. This particular check-in mostly works, but there are still issues. (check-in: 2e8d4fd4 user: drh tags: index-expr-opt) | |
| 16:48 | Move the rest of testing1.js into tester1.js and eliminate the dependency on jaccwabyt_test.c. Extend the list of default config-related #defines in sqlite3-wasm.c and reorganize them for maintainability. (check-in: 4e2a8aff user: stephan tags: trunk) | |
| 15:09 | Optimize the IS NULL and IS NOT NULL operators so that they avoid loading large strings or blobs off of disk if all it needs to know is whether or not the string or blob is NULL. (check-in: cb943501 user: drh tags: trunk) | |
