| 20:08 | Add window functions lag() and lead(). (check-in: ef34207073 user: dan tags: exp-window-functions) | |
| 18:13 | The IN-early-out optimization: When doing a look-up on a multi-column index and an IN operator is used on a column other than the left-most column, then if no rows match against the first IN value, check to make sure there exist rows that match the columns to the right before continuing with the next IN value. (check-in: 09fffbdf9f user: drh tags: trunk) | |
| 18:01 | Fix the assert()s in the byte-code engine that prove that cursors are unidirectional. (Closed-Leaf check-in: 4b0b4e1403 user: drh tags: multikey-opt-idea) | |
| 17:45 | Add support for window function first_value(). (check-in: 060b264028 user: dan tags: exp-window-functions) | |
| 17:32 | Remove the NextIfOpen and PrevIfOpen opcodes which are no longer needed when the IN-early-out optimization is working. (check-in: 439c816227 user: drh tags: multikey-opt-idea) | |
| 16:07 | Test cases. (check-in: 085e863713 user: drh tags: multikey-opt-idea) | |
| 15:54 | Fix problems with the nth_value() function. (check-in: 63002b9a09 user: dan tags: exp-window-functions) | |
| 15:28 | Merge the ".stat/.eqp" CLI fix from trunk. (check-in: a91cad3381 user: drh tags: multikey-opt-idea) | |
| 15:23 | • Fixed ticket [7be932dfa6]: Adverse interaction between .stats and .eqp in the CLI plus 5 other changes (artifact: 07775835d6 user: drh) | |
| 15:23 | Avoid using a prepared statement for ".stats on" after it has been closed by the ".eqp full" logic. Fix for ticket [7be932dfa60a8a6b3b26bcf76]. (check-in: bb87c054b1 user: drh tags: trunk) | |
| 15:11 | • New ticket [7be932dfa6] Adverse interaction between .stats and .eqp in the CLI. (artifact: facdb8d39f user: drh) | |
| 14:59 | Add the WHERE_IN_EARLYOUT flag and use it to clarify the logic of this optimization. (check-in: 522f1eacc2 user: drh tags: multikey-opt-idea) | |
| 14:32 | Merge recent trunk enhancements. (check-in: e9d7bf4f7b user: drh tags: multikey-opt-idea) | |

| 22:32 | In SQLITE_DEBUG mode, attempt to log the page number of the database that contained the problem when SQLITE_CORRUPT errors are seen. (check-in: e39795d7d7 user: drh tags: trunk) | |
| 19:46 | Fix another lsmtest build problem. Add the "-trans BOOLEAN" option to "lsmtest speed2". (check-in: 61853bc171 user: dan tags: lsm-vtab) | |
| 16:25 | Merge in trunk enhancements. (check-in: f8bbb608cb user: drh tags: prepare_v3) | |
| 15:55 | Add too/tserver.c - the implementation of a simple multi-threaded server designed for interactive testing of concurrency between connections used by different threads of the same process. (check-in: 05b4fc4340 user: dan tags: server-edition) | |
| 10:55 | Cause the ANALYZE command to build sqlite_stat1 table entries for empty tables with the assumption that such tables really contain 10 elements. This gives better query plans for tables that are truely empty, but is likely to cause problems in legacy systems, so the change is kept off trunk. Some TCL tests fail on this check-in due to the new stat1 entries. (Leaf check-in: c81f260c2d user: drh tags: analyze-empty-tables) | |
