| 20:13 | Fix to token destructors in Lemon. This does not impact SQLite. Ticket #2175. (CVS 3753) (check-in: 6195af4982 user: drh tags: trunk) | |
| 18:46 | Add the sqlite3_clear_bindings() API to the loadable extension interface. Ticket #2135. (CVS 3752) (check-in: 3111b43ec3 user: drh tags: trunk) | |
| 18:41 | Buffer updates per-transaction rather than per-update. If lots of updates happen within a single transaction, there was a lot of wasted encode/decode overhead due to segment merges. This code buffers updates in memory and writes out larger level-0 segments. It only works when documents are presented in ascending order by docid. Comparing a test set running 100 documents per transaction, the total runtime is cut almost in half. (CVS 3751) (check-in: 0229cba696 user: shess tags: trunk) | |
