| 19:54 | Begin fleshing out the key/value accessor implementation. This is an incremental check-in. (check-in: 02d60e196f user: drh tags: sqlite3_kv) | |
| 19:36 | Improve and update comments. (check-in: 2dc16d345b user: mistachkin tags: winSectorSize) | |
| 19:06 | Minimize the requested permissions when opening the volume on Windows 7 and Vista. (check-in: 8d429a59cd user: mistachkin tags: winSectorSize) | |
| 17:20 | Baseline interface definition for the experimental sqlite3_kv accessor object. (check-in: a435841e71 user: drh tags: sqlite3_kv) | |
| 01:11 | Add runtime version checking for winSectorSize. (check-in: cb9d1ab33d user: mistachkin tags: winSectorSize) | |
| 00:27 | When determining sector sizes on Windows 7 and Vista, make sure the target file is on the same volume as corresponding root directory. (check-in: de699ead5a user: mistachkin tags: winSectorSize) | |

| 10:41 | Fix a problem that could cause a spurious SQLITE_NOMEM error when attempting to resume an RBU operation if the previous client failed right after completing the incremental checkpoint. Also a "cannot vacuum wal db" error that could occur when resuming an RBU vacuum if an error (OOM or IO error) occurs during the incremental checkpoint. (check-in: 681d96eb82 user: dan tags: trunk) | |
| 00:10 | Disable intrinsic functions for Windows using Clang, due to reports of linkage errors. This causes a 0.6% performance reduction. We will want to revisit this change in the future. (check-in: 7fd560c6d2 user: drh tags: trunk) | |

| 18:10 | Back out check-in [0b3174e0b1364c] and replace it with a better fix for \ticket [91e2e8ba6ff2e2] - a fix that does not cause the problem identified by ticket [7ffd1ca1d2ad4ec]. Add new test cases for both tickets. (check-in: 9b64af7b52 user: drh tags: trunk) | |
| 16:43 | Back out check-in [0b3174e0b1364c] and replace it with a better fix for ticket [91e2e8ba6ff2e2] - a fix that does not cause the problem identified by ticket [7ffd1ca1d2ad4ec]. (Closed-Leaf check-in: 0613665274 user: drh tags: automatic-index-affinity) | |
| 16:01 | Add test cases for tickets [91e2e8ba6ff2e2] and [7ffd1ca1d2ad4ec]. (check-in: 9d0dfe0b08 user: drh tags: automatic-index-affinity) | |
| 11:54 | An example showing how to improve performance of sqlite3VdbeSerialPut() using the GCC intrinsic function __builtin_bswap64(). (Leaf check-in: e42ed9b4ad user: drh tags: builtin-bswap64) | |

| 22:21 | Merge updates from trunk. (check-in: 8b42b8e31a user: mistachkin tags: winSectorSize) | |
| 18:24 | Fix a problem preventing resumption of RBU operations after recovering from a process or system failure that occurs during the incremental-checkpoint phase. (check-in: 97914266cb user: dan tags: trunk) | |
| 12:53 | Fix the build for SQLITE_ENABLE_MEMORY_MANAGEMENT. (check-in: 8c85b8fdd7 user: drh tags: trunk) | |

| 23:37 | Attempt to detect physical sector sizes on Windows Vista and higher. (check-in: 6e388423c4 user: mistachkin tags: winSectorSize) | |
| 19:10 | Remove a branch that is probably unreachable, and which adds no value. (check-in: 9acc72381c user: drh tags: trunk) | |
| 16:21 | Fix harmless compiler warnings in the UPDATE code generator. (check-in: 385db26667 user: drh tags: trunk) | |
| 16:14 | Remove an unnecessary corruption test from the btree balancer. If corruption is present, it will be found harmlessly by later tests. (check-in: bddf39562d user: drh tags: trunk) | |
| 15:19 | Test case macros to show that the previous check-in is well tested. (Leaf check-in: bd8b977abb user: drh tags: extra-testcase-macros) | |
| 15:11 | Improved detection of cells that extend into the reserved space at the end of the page while adjusting overflow page pointers during autovacuum. (check-in: 8097712c9c user: drh tags: trunk) | |
| 11:52 | Remove invalid test case from cursorhints2.test (check-in: 163cc1b2f7 user: drh tags: trunk) | |
| 11:50 | Make sure Tcl_AppendResult() always has a NULL-pointer argument at the end. (check-in: c07aef6f90 user: drh tags: trunk) | |

| 21:03 | Changes to allow some multi-row UPDATE statements to avoid the two-pass approach. (check-in: 7ae6104a3e user: dan tags: trunk) | |
| 20:10 | Fix a problem causing the pre-update hook to be passed an incorrect rowid value in some single-pass multi-row updates. (Closed-Leaf check-in: 62257eb53c user: dan tags: onepass-update) | |
| 19:03 | Fix a problem with single-pass multi-row UPDATE statements that invoke REPLACE conflict handling. (check-in: 0a2b8e1b9d user: dan tags: onepass-update) | |
| 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.
