| 21:01 | Begin adding instrumentation to record and report on the set of key-ranges a concurrent transaction reads from the database. (check-in: c39e3c14a9 user: dan tags: begin-concurrent-report) | |
| 16:31 | Update test file exclusive.test so that it works with the "journaltest" permutation. (check-in: 4daf94d833 user: dan tags: trunk) | |
| 16:23 | Fix a problem with using views in SQLITE_OMIT_VIRTUAL_TABLE builds. Also some test case fixes required for the same builds. (check-in: 934ee8bdb4 user: dan tags: trunk) | |
| 15:01 | Fix a case in fts3auto.test that fails for SQLITE_DISABLE_FTS4_DEFERRED builds. (check-in: d241055ead user: dan tags: trunk) | |
| 14:42 | Fix an assert() that could fail in SQLITE_MUTATION_TEST builds following an error in a query that uses CTEs. (check-in: c7e29458a7 user: dan tags: trunk) | |
| 13:40 | Fix a problem in the userauth extension causing it to occasionally set "PRAGMA count_changes" (and some others) to true. (check-in: 3a62f64222 user: dan tags: trunk) | |
| 12:29 | Fix the series.c and spellfix.c extensions to use SQLITE_VTAB_INNOCUOUS correctly. Fix the documentation on sqlite3_vtab_config() to take into account SQLITE_VTAB_INNOCUOUS and SQLITE_VTAB_DIRECTONLY. (check-in: 9265cb7f02 user: drh tags: trunk) | |
| 01:45 | Improvements to the autoconf TEA Makefile for MSVC. (check-in: cffcf12f03 user: mistachkin tags: trunk) | |

| 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) | |

| 18:25 | Change sqlite3StrAccumAppend() to use realloc instead of malloc. (check-in: 380f61df07 user: dan tags: trunk) | |
| 18:18 | Adjustments to the result row estimator for the IN operator so that it gives the same estimates as the equivalent OR operator. Test cases for the same. (check-in: c82cb9c028 user: drh tags: stat2-enhancement) | |
| 16:27 | Make use of histogram data to make better estimates for the number of rows that will be returned from "x IN (v1,v2,v3,...)" constraints. (check-in: fd3977a27a user: drh tags: stat2-enhancement) | |
| 15:52 | Add options to test command [do_faultsim_test] to support testing VFS implementations. (check-in: 503ad889da user: dan tags: trunk) | |
| 14:37 | Add the ability to use indices when a range contraint is bounded on the lower end by NULL. (check-in: f73a167b43 user: drh tags: stat2-enhancement) | |

| 22:19 | Do not flatten subqueries in a join where the subquery includes a LIMIT. Ticket #1634. This is just an initial fix. Many test cases need to be added prior to closing the ticket. (CVS 2987) (check-in: af18c0f431 user: drh tags: trunk) | |
| 19:57 | Fix a bug in os.h. How did this slip by before now? (CVS 2986) (check-in: 29725de474 user: drh tags: trunk) | |
| 12:08 | Fix more problems with malloc() and IO failures. (CVS 2985) (check-in: 29281dea81 user: danielk1977 tags: trunk) | |
