| 16:52 | Attempt to detect physical sector sizes on Windows 8 and higher. check-in: 381fd34b user: mistachkin tags: winSectorSize | |
| 14:15 | In the STAT4 computations, ensure that the aAvgEq values do not go negative. check-in: f58f75b5 user: drh tags: trunk | |

| 17:37 | Add a test case for ticket [25e335f802dd]. check-in: e500c15a user: dan tags: trunk | |
| 17:33 | Throw an error if the ON clause of a LEFT JOIN references tables to the right of the ON clause. Fix for ticket [25e335f802dd]. check-in: c92ecff2 user: drh tags: trunk | |
| 16:09 | Avoid unnecessary calls to the xRoundup() method of the memory allocator when the soft heap limit is not set. check-in: 4209b89e user: drh tags: trunk | |
| 15:08 | Fix a potential assertion fault discovered by OSS-Fuzz. check-in: 71c03b59 user: drh tags: trunk | |

| 20:57 | Merge latest changes from trunk, and also move the perf-counter into the inner loop of sqlite3BtreeMovetoUnpacked(). Leaf check-in: ff9eab95 user: drh tags: vdbe-aux-perf | |
| 19:55 | Remove a redundant assignment statement. check-in: a5fa0965 user: drh tags: trunk | |
| 19:27 | Performance optimization and size reduction in the OP_Variable opcode. check-in: 237aa974 user: drh tags: trunk | |
| 18:22 | Fix typo in a comment. No changes to code. check-in: d38fd229 user: mistachkin tags: trunk | |
| 18:20 | Try to move OP_Concat operations outside the inner loop. This turns out to make things very slightly slower, at least in speedtest1.c. Closed-Leaf check-in: 8a90f691 user: drh tags: failed-optimization | |
| 15:44 | Modify the OP_RowData opcode so that when P3!=0 it is allowed to hold an ephemeral copy of the content. This avoids unnecessary memcpy() operations in the xfer-optimization and VACUUM. check-in: 6e106acd user: drh tags: trunk | |
| 13:43 | Add the SQLITE_UINT64_TYPE compile-time option. check-in: a5fe03bc user: drh tags: trunk | |

| 14:47 | Improvements to the iIdxNoSeek optimization of sqlite3GenerateRowDelete() so that it is automatically disabled for BEFORE triggers but works in all other cases. check-in: 3178ec4c user: drh tags: trunk | |
| 14:26 | Critical fix to the previous check-in so that it works when there are BEFORE triggers that move the cursor before the OP_Delete has a chance to be applied. check-in: db2c0960 user: drh tags: trunk | |
| 03:26 | Avoid an unnecessary btree seek while deleting an index entry due to a conflict on a REPLACE operation. check-in: f0495c51 user: drh tags: trunk | |
| 00:56 | Avoid duplicate b-tree searches in the duplicate row detector used to implement DISTINCT. check-in: d577dda0 user: drh tags: trunk | |
