| 04:45 | Fix a problem in the omit-table-from-left-join optimization from check-in [0cd82ee9a8413cf] that was discovered by OSSFuzz. (check-in: b016c28fa5 user: drh tags: trunk) | |
| 00:45 | Completely disable the skip-ahead-distinct optimization for all but the inner-most loop of a DISTINCT join. Fix for ticket [ef9318757b152e3a26e9592] (check-in: b7595cf2ca user: drh tags: trunk) | |

| 23:47 | An experimental optimization to DISTINCT that causes an immediate exit of the inner loop of a join following each output row if the inner loop does not contribute any columns to the result set. (Leaf check-in: a33f88acd7 user: drh tags: distinct-early-out) | |
| 23:38 | Fix the skip-ahead-distinct optimization on joins for cases there the table in the inner loop of the join does not contribute any columns to the result set. Proposed fix for ticket [ef9318757b152e3a2] (check-in: 2dcef5a9ae user: drh tags: trunk) | |

| 15:46 | Fix a problem preventing the planner from identifying scans that visit at most one row in cases where that property is guaranteed by a unique, not-null, non-IPK column that is the leftmost in its table. (check-in: 7fdb1e2ac2 user: dan tags: trunk) | |

| 21:01 | Improved fix for ticket [da78413751863] that does not require disabling the query flattener as was done in [005d5b870625]. This also makes the code generator for vector IN operators a little easier to understand. (check-in: 723f1be3d4 user: drh tags: trunk) | |

| 20:48 | In the LSM extension, ensure that empty space on pages is zeroed before they are written to disk. This helps with compressed databases, and stops valgrind complaining about uninitialized bytes and write(). (check-in: 5ffec5db33 user: dan tags: trunk) | |
| 19:17 | Merge the latest changes, and the stmtvtab1.test fix, from trunk. (check-in: 85247880a6 user: drh tags: apple-osx) | |

| 23:48 | In the parse tree, combine LIMIT and OFFSET into a single expression rooted on a TK_LIMIT node, for a small code size reduction and performance increase, and a reduction in code complexity. (check-in: 3925facd94 user: drh tags: trunk) | |
| 21:06 | Fix a typo that prevented successful builds on macs. (check-in: adf83060a6 user: drh tags: apple-osx) | |

| 20:06 | Merge changes from trunk. This fixes the SQLITE_ENABLE_UPDATE_DELETE_LIMIT functionality so that it works with views and WITHOUT ROWID tables. (check-in: d90e5f346b user: dan tags: begin-concurrent) | |

| ||
| 05:51 | Remove some branches in walTryBeginRead() that were added by check-in [ce5d13c2de] but became unreachable with the addition of logic in check-in [18b26843] that enabled read-only clients to parse the WAL file into a heap-memory WAL-index, thus guaranteeing that the WAL-index header is always available. (check-in: 9c6b38b9a9 user: drh tags: readonly-wal-recovery) | |
|
2017-11-11
| ||
