| 19:59 | Within a loop that uses a non-covering index test, test non-indexed terms that can be tested without seeking the main table cursor before those that cannot. (check-in: afe68f0a80 user: dan tags: pushdown-optimization) | |
| 17:32 | Fix various bugs revealed by running performance tests. (check-in: a40b42c422 user: dan tags: server-edition) | |
| 14:09 | Add a missing releasePage() call to the server-mode free-list management code. (check-in: a5a085483c user: dan tags: server-edition) | |
| 10:20 | Use a different free-list format for server-mode databases in order to reduce contention. (check-in: 778e8a102d user: dan tags: server-edition) | |

| 22:29 | Further simplifications and improved commentting on the rowset.c module, including several optimization comments. (check-in: 9f15a520de user: drh tags: trunk) | |
| 20:11 | Comment changes only: Add several optimization marks in rowset.c. Add a header comment that explains what the various special comments mean. (check-in: 8cdbe89ac6 user: drh tags: trunk) | |
| 19:23 | Fix typo in comment. No changes to code. (check-in: 9f6f17b5c9 user: mistachkin tags: trunk) | |
| 18:53 | Rearrange some code in the RowSet logic for clarity of presentation, while adding an /*OPTIMIZATION-IF-TRUE*/ comment. It should operate identically. (check-in: 5748e64376 user: drh tags: trunk) | |
| 14:59 | Merge latest changes from trunk with this branch. (check-in: 45467ee498 user: dan tags: permutations-fix) | |
| 14:54 | Avoid running sessionfault.test and sessionfault2.test as part of the "inmemory_journal" permutation. (check-in: 5973d3bf2e user: dan tags: permutations-fix) | |
| 14:15 | Use comments to mark several branches as optimizations. No changes to code. (check-in: 33e6274727 user: drh tags: trunk) | |
| 09:53 | Ensure that quota.test deletes the directory named "test.db" that it creates. (check-in: 045edd4b17 user: dan tags: permutations-fix) | |
| 03:52 | Remove an unnecessary conditional from the sqlite3DecOrHexToI64() routine. (check-in: fcf85bfe50 user: drh tags: trunk) | |
| 00:32 | Change the sqlite3Atoi64() routine so that it returns failure if not all of the input characters are consumed, even if it consumed all characters up to the first 0x00. This has no impact on external APIs as far as I can tell. (check-in: 46d4ffff3b user: drh tags: trunk) | |

| 23:34 | Revise when the sqlite3ErrName() function is defined. (Closed-Leaf check-in: 9e593fb3db user: mistachkin tags: winTest) | |
| 20:24 | Fix an fts5 bug in handling writes while there are active cursors. (check-in: 07f7095539 user: dan tags: fts5) | |
| 18:35 | Improve coverage of fts5 tests. (check-in: 8e8136f2dc user: dan tags: fts5) | |
| 14:49 | Update the test/fuzzdata1.txt file with the latest cases discovered by AFL. (check-in: f2063f5320 user: drh tags: trunk) | |
| 14:07 | Fix an assert() failure that could occur if the internal sqlite3_rename_parent() SQL scalar function was invoked directly. (check-in: 36e5152618 user: dan tags: trunk) | |
| 14:00 | Fix sqlite3VdbeMakeWritable() to always clear the MEM_Ephem flag. Change the OP_Move opcode to always deephemeralize moved content. (check-in: fbb0672718 user: drh tags: trunk) | |
| 13:20 | • Edit [091cfe8e0a89c64f|091cfe8e0a]: Move to branch mistake. Mark "Closed". Edit check-in comment. (artifact: c22b0dcf8f user: drh) | |
| 13:11 | Oops - the deephemerialization needs to occur before the move, not after. Was: Rather than try to keep track of the parent of an ephermeral register when the register moves, just deephemeralize all registers touched by the OP_Move opcode. (Closed-Leaf check-in: 091cfe8e0a user: drh tags: mistake) | |
| 12:44 | Shift the Mem.pScopyFrom pointer in the correct direction in OP_Move. Fix for a defective check-in [a2135ad13049] and ticket [d6352363751]. Debugging code only - does not affect normal operation. (check-in: add4e043b3 user: drh tags: trunk) | |
| 12:27 | Add code to the shell to optionally initialize the dbstat virtual table. (Closed-Leaf check-in: 7ed86dd3b8 user: drh tags: stat-vtab-in-shell) | |
| 01:28 | Fix comment typos. No code changes. (check-in: 60174cf572 user: drh tags: trunk) | |
| 00:53 | Add a TCL script that can be run to generate the fuzzdata1.txt file. (check-in: fdc79fd14a user: drh tags: trunk) | |

| 20:11 | Do not reduce the number of rows scanned at all for "IS NOT NULL" constraints. Fix a bug in calculating the number of rows visited by scans of partial indicies. (check-in: a8ae93f0cf user: dan tags: experimental-costs) | |
| 19:34 | The trunk assumes that an open range constraint on an indexed term (col>?) term matches 1/4 of the indexed rows, and that a closed constraint (col BETWEEN ? AND ?) matches 1/64. Change this branch to do the same. (check-in: 4047ac75e2 user: dan tags: experimental-costs) | |
| 18:02 | Merge all recent trunk enhancements and fixes into the sessions branch. (check-in: e158812c34 user: drh tags: sessions) | |
| 17:57 | • Edit [02610cd9b77caa2c|02610cd9b7]: Mark "Closed". (artifact: f911f866d8 user: drh) | |
| 17:56 | Add the sqlite3_rtree_query_callback() API to the RTree virtual table. (Cherrypick from the sessions branch.) (check-in: af2cbe64ad user: drh tags: trunk) | |
| 17:51 | Add the sqlite3_rtree_query_callback() API to the RTree virtual table. (check-in: 3dca280935 user: drh tags: sessions) | |
| 15:11 | Update unordered.test to take into account for the fact that SQLite now prefers a full-table scan over a non-covering index scan that visits a large percentage of the table rows. (check-in: 20f468dfbc user: dan tags: experimental-costs) | |
| 12:08 | Add an extra column to a table in analyze9.test to give the planner a little more reason to select an index. (check-in: 1b95544f84 user: dan tags: experimental-costs) | |
| 10:00 | Update test script analyze3.test to account for the fact that SQLite now prefers a full-table scan over a non-covering index scan that visits a large percentage of the table rows. (check-in: 35f46a55d8 user: dan tags: experimental-costs) | |
| 09:35 | Modify internal function whereLoopAdjustCost() so that it does not prefer a skip-scan over a regular index scan even if the regular scan uses a subset of the WHERE terms used by the skip-scan. (check-in: 88a5758dcc user: dan tags: experimental-costs) | |
| 08:49 | Fix an error in estimating of the number of rows visited by a range scan. (check-in: d491de62fc user: dan tags: experimental-costs) | |

| 20:35 | Allow SQLITE_MAX_COLUMN to be set to zero at compile-time in order to disable the checks. Also SQLITE_MAX_EXPR_DEPTH. Ticket #3069. (CVS 5065) (check-in: e6f71abb22 user: drh tags: trunk) | |
| 20:27 | Add test cases to verify that multiple virtual tables can be updated within a trigger and that xSync, xCommit, and xRollback are never called except following xBegin or xCreate. Ticket #3083. (CVS 5064) (check-in: 76175199ac user: drh tags: trunk) | |
| 18:46 | Make sure that transactions are started on all virtual tables that changes in a single statement, not just the first. Ticket #3083. Need to add test cases. (CVS 5063) (check-in: 133b7ee50e user: drh tags: trunk) | |
| 17:41 | Modified Varint32 functions to disable code for single-byte handling as it is already handled by their respective macro forms. (CVS 5062) (check-in: be10f5dda6 user: shane tags: trunk) | |
| 17:12 | Add tests to create and drop a virtual table during a recursive call from an application-defined function. Ticket #3080. (CVS 5061) (check-in: d4d6eff353 user: drh tags: trunk) | |
| 16:55 | Change the implementation of the NaN recognition to be more cross-platform. Ticket #3089. (CVS 5060) (check-in: 07fd9a8c6c user: drh tags: trunk) | |
