| 15:31 | Fix a problem causing the LEFT JOIN strength reduction optimization to be incorrectly applied in some cases where the WHERE clause of the query contains a filter expression of the form "lhs.x IS NOT ?". check-in: 1fdaf2c344 user: dan tags: trunk | |

| 20:36 | Minor changes to the input grammar resulting in a faster and slightly smaller parser. check-in: a2c443c0ee user: drh tags: trunk | |
| 15:57 | Enhance the query planner so that it detects when the xBestIndex method of a virtual table gives out-of-sequence argvIndex values and reports an error. Secondary fix for ticket [2b8aed9f7c9e6]. check-in: 9506ec14fb user: drh tags: trunk | |
| 14:26 | Fix the fts5 xBestIndex method so that it is not confused by "IS", "!=", "REGEXP", "GLOB" or "LIKE" operators. Fix for ticket [2b8aed9f]. check-in: a0ca4ddbbf user: dan tags: trunk | |
| 13:58 | Improvements to ".wheretrace" output. check-in: ea2e5b34bf user: drh tags: trunk | |

|

| 15:04 | More complete parsing of UPSERT, including UPSERT within a trigger. The sqlite3Insert() logic to actually perform the UPSERT is not yet implemented, however. check-in: 5cc2a5a315 user: drh tags: upsert | |
|
2018-04-06
| ||
| 19:36 | Demonstration of how the parser can be augmented to recognize a PostgreSQL-style UPSERT. This check-in implements parsing only. check-in: 9b22905b15 user: drh tags: upsert | |

| 16:22 | Fix a problem in the sessions module causing sqlite3session_apply_strm() to allocate enough memory for the entire input buffer - which defeats the point of a streaming interface. check-in: 7594e60935 user: dan tags: trunk | |
|
2018-04-05
| ||
| 16:26 | Fix an instance where an uninitialized VM register might be accessed. Fix for [093420fc0]. This problem was found by OSSFuzz. check-in: a3b02db746 user: dan tags: trunk | |

| 14:25 | Fix the generate_series virtual table so that it correctly returns no rows if any of its constraints are NULL. Ticket [fac496b61722daf28]. check-in: 3328e828e2 user: drh tags: trunk | |
| 14:04 | Change the LEFT JOIN strength reduction optimization so that assumes that virtual table constraints can be true even if terms within the constraint are NULL. This works around dodgy virtual table implementations. Fix for ticket [fac496b61722daf2]. check-in: cbb977fe19 user: drh tags: trunk | |

| 00:16 | Better solution to the LIKE problem from the previous check-in that works even if the SQLITE_LIKE_DOESNT_MATCH_BLOBS compile-time option is used. check-in: b850dd1599 user: drh tags: trunk | |
|
2018-03-31
| ||

|
2018-03-30

| 21:05 | Do not inject OOM errors on SQLITE_FCNTL_LOCK_TIMEOUT calls as an OOM is not possible in that context. Closed-Leaf check-in: 5474e560ee user: drh tags: lowlevel-lock-timeout | |
