| 23:18 | Enhance the btree search routine so that it does early detection of impossibly large keys and thereby avoids a large malloc() call. (check-in: 3ecaaee69f user: drh tags: trunk) | |
| 17:57 | Avoid deferencing a freed pointer following an OOM or SQLITE_CORRUPT error in the fts3 xDestroy method. (check-in: 505ed9a478 user: dan tags: trunk) | |
| 16:12 | Remove a faulty assert() from fts3. (check-in: 6c33a303eb user: dan tags: trunk) | |
| 16:01 | Make sure the extra bytes allocated for the saved cursor position by check-in [160b1e31c0f27257] are initialized to zero. (check-in: 2737564929 user: drh tags: trunk) | |
| 14:55 | Add the --memtrace option to the CLI. (check-in: a1e12fa2a8 user: drh tags: trunk) | |
| 14:49 | Minor fix the fallocate.test module change from [7cd56cad5efead5] (check-in: 94fb7a4700 user: drh tags: trunk) | |
| 13:47 | Add the --max-data and --max-as options to dbfuzz2. Also cause dbfuzz2 to show its maximum RSS size upon exit in standalone mode with the -v option. (check-in: 7ce93e824a user: drh tags: trunk) | |

| 21:47 | A better implementation of the moveto-neighbor optimization that checks for nearby rows on adjacent pages. (Closed-Leaf check-in: 2c4ecb85a4 user: drh tags: btree-moveto-neighbor) | |
| 21:47 | • Edit [8e5cfb2039126da7|8e5cfb2039]: Move to branch btree-moveto-neighbor. (artifact: 3be615f545 user: drh) | |
| 16:54 | B-tree optimization: When seeking on a rowid table that has already been positioned, check to see if the new row happens to be the next row on the same leaf page. That is a reasonably common case, and if it is true it avoids a full binary search. (check-in: 8e5cfb2039 user: drh tags: btree-moveto-neighbor) | |
| 16:27 | Change sqlite3_blob_reopen() to call sqlite3VdbeExec() directly rather than going through sqlite3_step(). Performance enhancement. (check-in: 347df3c1fd user: drh tags: trunk) | |
| 16:21 | Fix problems in the previous commit. (Leaf check-in: 74ad80eb74 user: dan tags: trigger-trace) | |
| 15:58 | Add extra (somewhat inefficient) trace callbacks for triggers if SQLITE_TRACE_TRIGGER is defined. (check-in: ffda1d1e1c user: dan tags: trigger-trace) | |
| 15:55 | In the kvtest.c test utility, reuse the buffer into which blobs are read, rather than reallocating it for each row. This is a closer match to how other test programs work, and thus provides a better comparison. (check-in: 0d1ad13a29 user: drh tags: trunk) | |
| 15:30 | A proof-of-concept for running sqlite3_blob_open() without using OP_Column when operating on a pure key/value table. This demo does not include any corrupt database checking. Uses about 3% fewer CPU cycles on a key/value performance test. (Leaf check-in: 4cda3b305b user: drh tags: kv-access-opt-demo) | |
| 14:11 | Remove an unnecessary sqlite3_bind_int64() call from sqlite3_blob_open(). Also other minor refactoring of the sqlite3_blob implementation. (check-in: 9d197a5323 user: drh tags: trunk) | |

| 18:56 | Fix typo in 'Makefile.in'. (check-in: 29a51c6dcc user: mistachkin tags: trunk) | |
| 17:25 | Disable the RESTRICT foreign key action if "PRAGMA defer_foreign_keys" is set. (Closed-Leaf check-in: 82470d1c3a user: dan tags: disable-restrict) | |
| 17:06 | Add a new hint bit on the flags parameter of sqlite3BtreeDelete(). The new BTREE_IDXDELETE bit indicates that the call is to delete an index entry corresponding to a table row that has already been deleted. (check-in: ac2cbadd80 user: drh tags: btree-fordelete-flag) | |
| 15:55 | Improved comments on the FORDELETE hint. No logic changes. (check-in: a3cec529f0 user: drh tags: trunk) | |

| 18:23 | Fix an fts5 issue with loading doclist-indexes for a term that is the last thing on its leaf page. (check-in: e0d614425f user: dan tags: fts5) | |
| 17:20 | Merge trunk changes with this branch. (check-in: f8699a1a3b user: dan tags: fts5) | |
| 17:00 | Fix an assert() that may fail following an OOM error. (check-in: 5f592359d6 user: dan tags: trunk) | |
| 16:10 | Add further tests for fts5 backend. (check-in: 09dabb3b9e user: dan tags: fts5) | |
| 06:36 | Merge latest trunk changes with this branch. (check-in: b3348b1e07 user: dan tags: fts5) | |
| 00:51 | Fix harmless compiler warning seen with MSVC. (check-in: 78c2e62bb4 user: mistachkin tags: trunk) | |
| 00:48 | Enhancements to entropy generation for the Win32 VFS. (check-in: 26190b3c63 user: mistachkin tags: trunk) | |

| 23:13 | • Fixed ticket [1258875e07]: Undefined collating sequence on LIKE causes segfault plus 3 other changes (artifact: 69302bfe88 user: drh) | |
| 23:11 | Fix a segfault that can occur when the LHS of a LIKE operator has an undefined collating sequence. Ticket [1258875e07553]. (check-in: a82e6b4585 user: drh tags: trunk) | |
| 23:05 | • New ticket [1258875e07] Undefined collating sequence on LIKE causes segfault. (artifact: 6477f5ee07 user: drh) | |
| 01:53 | Redesign the string to numeric value caster so that it is more likely to work on unusual floating point hardware. (check-in: 8bb1104c6f user: drh tags: trunk) | |
