| 19:20 | Ensure that test tool "tserver" finalizes all statements before attempting to close a database handle. (check-in: d8568aacf0 user: dan tags: server-edition) | |
| 18:19 | Rename the azCompileOpt global constant to avoid a harmless compiler warning about a name conflict with a local variable. (check-in: 94e420ecfb user: drh tags: trunk) | |
| 18:13 | • Fixed ticket [892fc34f17]: Incorrect query result when a LEFT JOIN subquery is flattened plus 5 other changes (artifact: 879fcac86a user: drh) | |
| 17:43 | Ensure that the query planner knows that any column of a flattened LEFT JOIN can be NULL even if that column is labeled with "NOT NULL". Fix for ticket [892fc34f173e99d8]. (check-in: 483462682d user: dan tags: trunk) | |
| 16:15 | • New ticket [892fc34f17] Incorrect query result when a LEFT JOIN subquery is flattened. (artifact: d28d654485 user: drh) | |

| 17:25 | For a table on the rhs of a LEFT JOIN operator, do not include terms like "IS NULL" from the WHERE clause in the cursor-hint. These may be false for rows that the cursor would otherwise visit, but true for a row of all NULL values generated by the LEFT JOIN. (check-in: 913e595615 user: dan tags: trunk) | |
| 17:22 | Allow LIKE operators that appear in a WHERE clause to be included in the cursor-hint for a cursor on the rhs of a LEFT JOIN. (Closed-Leaf check-in: 7455d932f5 user: dan tags: cursor-hints) | |

| 18:13 | Split out all four cases of cellSizePtr() into different methods, each optimized for the specific page type. This gives a 0.36% performance increase at a cost of about 300 bytes of code. (Leaf check-in: 522502ec18 user: drh tags: btree-opt) | |
| 14:11 | Update the fuzztest data using the latest test vectors discovered by AFL. (check-in: b97f9cf73e user: drh tags: trunk) | |
| 13:18 | Make sure that the likelihood() function does not mess up generation of result-set code when it is used (inappropropriately) in a result-set expression. (check-in: 7cdbae625e user: drh tags: trunk) | |

| 13:55 | Improved display of record data in the "NNNbd" output of the showdb.exe utility program. (check-in: f735c2497e user: drh tags: trunk) | |
| 01:32 | In the showdb.exe utility, for the "NNNbd" command, also show data fields in addition to header fields on each record decoded. Improvements to formatting. (check-in: b451fe0cb9 user: drh tags: trunk) | |

| 19:55 | Add tests for modifying the docid and languageid fields of an fts table with a non-zero languageid_bits field. (Closed-Leaf check-in: 949425d467 user: dan tags: fts-languageid-bits) | |
| 19:07 | Use the target platorm version in the VS props file as well. (check-in: ce5a8cc1cf user: mistachkin tags: vsix2013) | |
| 18:53 | VSIX tooling changes to support Visual Studio 2013. (check-in: c5954c58c0 user: mistachkin tags: vsix2013) | |
| 18:32 | Fix some issues related to ORDER BY and fts tables with a non-zero languageid_bits setting. (check-in: 81527768ef user: dan tags: fts-languageid-bits) | |
| 17:32 | Add a NEVER() macro and an explanation comment around an unreachable branch in the STAT3 logic. (check-in: 604c3c5de6 user: drh tags: nextgen-query-plan-exp) | |
| 16:22 | Add extra tests for fts with a non-zero languageid_bits setting. Fix querying by docid with the same. (check-in: b1df00f3f1 user: dan tags: fts-languageid-bits) | |
| 14:17 | Pull in the posix_fallocate() change from trunk. (check-in: d94db3fd92 user: drh tags: nextgen-query-plan-exp) | |
| 14:07 | Disable posix_fallocate() for all systems, all the time, unless the HAVE_POSIX_FALLOCATE compile-time macro is supplied. (check-in: b674462243 user: drh tags: trunk) | |
| 11:48 | Add tests (and a fix) for large and small fts docid values with various languageid_bits settings. (check-in: 8dc261b765 user: dan tags: fts-languageid-bits) | |
| 11:01 | Fix fts handling of the case where both a rowid and docid are specified as part of an insert statement. (check-in: 610e7e9612 user: dan tags: fts-languageid-bits) | |
| 01:27 | The vtshim xCreate and xConnect functions need to store the pAux pointer into the newly created vtable object. Style fixes. (check-in: 43913c7bd5 user: mistachkin tags: disposable-vtable) | |
| 00:20 | Integration adjustments for the vtshim module. (check-in: bf2e28ddb2 user: mistachkin tags: disposable-vtable) | |

| 18:13 | Add new Compare and Jump codes to the virtual machine. Use them in the implementation of aggregate queries. (CVS 5257) (check-in: 083113652f user: drh tags: trunk) | |
| 17:51 | Add a test to check that opening a second connection to a shared cache does not reset the cache size to its default value. (CVS 5256) (check-in: 3546e245aa user: danielk1977 tags: trunk) | |
| 15:24 | Change the SRT_Subroutine mode into SRT_Coroutine. Use co-routines in the INSERT processing logic. (CVS 5255) (check-in: 6b9d92fc3f user: drh tags: trunk) | |
| 14:59 | Add a mode to the sqlite3_test_control() interface to register hooks called at the beginning and end of "benign malloc failure" blocks. This allows malloc() failure testing to be done using public APIs only. (CVS 5254) (check-in: 56c8af1452 user: danielk1977 tags: trunk) | |
| 11:05 | Move (almost all) malloc failure test logic from fault.c to test_malloc.c. (CVS 5253) (check-in: 4ae21e3419 user: danielk1977 tags: trunk) | |
