| 16:52 | Attempt to detect physical sector sizes on Windows 8 and higher. check-in: 381fd34b97 user: mistachkin tags: winSectorSize | |
| 15:42 | Fix a problem preventing UPDATE statements that use a range-scan on the PK index of a WITHOUT ROWID table from using a one-pass strategy. check-in: cab86c9094 user: dan tags: onepass-update | |
| 14:21 | In the STAT4 computations, ensure that the aAvgEq values do not go negative. check-in: 4f83f6806a user: drh tags: branch-3.8.9 | |
| 14:15 | In the STAT4 computations, ensure that the aAvgEq values do not go negative. check-in: f58f75b5a0 user: drh tags: trunk | |

| 20:04 | Changes to allow some multi-row UPDATE statements to avoid the two-pass approach. check-in: 46db23ccd1 user: dan tags: onepass-update | |
| 17:37 | Add a test case for ticket [25e335f802dd]. check-in: e500c15a9f 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: c92ecff2ec 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: 4209b89eab user: drh tags: trunk | |
| 15:08 | Fix a potential assertion fault discovered by OSS-Fuzz. check-in: 71c03b59b6 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: ff9eab9587 user: drh tags: vdbe-aux-perf | |
| 19:55 | Remove a redundant assignment statement. check-in: a5fa09657b user: drh tags: trunk | |
| 19:27 | Performance optimization and size reduction in the OP_Variable opcode. check-in: 237aa97452 user: drh tags: trunk | |
| 18:22 | Fix typo in a comment. No changes to code. check-in: d38fd22935 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: 8a90f69139 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: 6e106acd74 user: drh tags: trunk | |
| 13:43 | Add the SQLITE_UINT64_TYPE compile-time option. check-in: a5fe03bc41 user: drh tags: trunk | |
| 07:00 | Merge the "changebatch" functionality into this branch. check-in: 50fb1eb368 user: dan tags: begin-concurrent | |
| 06:53 | Disable the optimization from [8cb8516d] (omit TableLock instructions for non-sharable databases) on this branch. This branch uses the TableLock instructions to ensure that the db schema is not written from within a BEGIN CONCURRENT transaction. check-in: c8ca3e0a8d user: dan tags: begin-concurrent | |
| 06:33 | Upgrade this branch to 3.16 plus the various fixes that appeared after its release. check-in: d0e212d08f user: dan tags: begin-concurrent | |

| 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: 3178ec4c27 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: db2c0960ff 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: f0495c5133 user: drh tags: trunk | |
| 00:56 | Avoid duplicate b-tree searches in the duplicate row detector used to implement DISTINCT. check-in: d577dda0a7 user: drh tags: trunk | |
| 00:42 | This hack illustrates how to use the VDBE_PROFILE mechanism to show which bytecode operators are using resources other than time. In this case, the number of loops through the binary search code in sqlite3BtreeMovetoUnpacked() is measured, for the purpose of helping to identify unnecessary btree searches. check-in: 746b183683 user: drh tags: vdbe-aux-perf | |

| 13:52 | Ensure that "PRAGMA case_sensitive_like" and "PRAGMA shrink_memory" set the number of output columns to 0 (as they are statements that return no data). check-in: 4a97ba4ee0 user: dan tags: branch-3.16 | |
| 13:49 | Ensure that "PRAGMA case_sensitive_like" and "PRAGMA shrink_memory" set the number of output columns to 0 (as they are statements that return no data). check-in: 6696cd1878 user: dan tags: trunk | |

| 20:01 | Ensure that sqlite3_column_count() returns 0 for the "set" mode of "get/set" PRAGMA statements that do not return a value in that case (e.g. page_size, cache_size, auto_vacuum). check-in: e745da6b14 user: dan tags: branch-3.16 | |
| 20:00 | Ensure that sqlite3_column_count() returns 0 for the "set" mode of "get/set" PRAGMA statements that do not return a value in that case (e.g. page_size, cache_size, auto_vacuum). check-in: 2f57939a55 user: dan tags: trunk | |

| 17:27 | Version 3.16.2 second release candidate check-in: 285c5a54dd user: drh tags: branch-3.16 | |
| 17:25 | Fix handling the case where a sub-query in a FROM clause is itself a UNION ALL, and one side of that UNION ALL is a query on a view that includes an ORDER BY. Fix for ticket [190c2507]. check-in: ec1e85a657 user: dan tags: branch-3.16 | |
| 17:23 | Fix handling the case where a sub-query in a FROM clause is itself a UNION ALL, and one side of that UNION ALL is a query on a view that includes an ORDER BY. Fix for ticket [190c2507]. check-in: 590ca83b8e user: dan tags: trunk | |

| 13:52 | Ensure that the sqlite3_value_text() interface returns a buffer that is long enough to hold the complete string plus the zero terminator even when the input is a zeroblob. Fix for a problem detected by OSS-Fuzz. check-in: ca185808ad user: drh tags: branch-3.16 | |
| 13:50 | Fix problems in trigger and foreign key handling when doing REPLACE on a WITHOUT ROWID table that has no secondary indexes. Fix for ticket [30027b613b4]. check-in: 571f166ea8 user: drh tags: trunk | |

| 22:02 | Improved the comment on the block of code the provides the performance optimization originally added by check-in [925840cfdb]. The original check-in omitted condition 4, which was the cause of bug [30027b613b]. check-in: c6506b82aa user: drh tags: replace-fix | |
