| 01:18 | The ALTER TABLE fix of check-in [7e5ad8e0ab7ee91a] is no longer needed due to the changes at check-in [4cf8721f5ceb1fda]. But, we keep the defense in place as an assert() for extra safety. (Leaf check-in: 230556e8 user: drh tags: trunk) | |
| 00:54 | Remove dead code that was added during initial development of RENAME COLUMN but never actually served a purpose. (check-in: c95c4cda user: drh tags: trunk) | |

Also, avoid factoring out constant expressions on the LHS of an IN(...) operator, as the IN(...) operation may affect the affinity of these values. Fix for [fd1bda016d1]. (Leaf check-in: 43612157 user: drh tags: branch-3.31) | |

|
2020-03-27
| ||
| 17:23 | Modifications to the way blocking locks are used in SQLITE_ENABLE_SETLK_TIMEOUT builds so that multiple processes or threads may not deadlock when operating on a single database. (Closed-Leaf check-in: c516027d user: dan tags: setlk-deadlock-fix) | |
|
2020-03-26

Ticket [82b588d342d515d1] (check-in: 8b437b47 user: drh tags: trunk) | |

| 19:56 | Do not factor out constant functions into the initialization section of a prepared statement, because even though they are constant, they can still throw exceptions. Instead, put such functions in an OP_Once block. This fixes ticket [3c9eadd2a6ba0aa5] and causes COALESCE() and CASE...END to be short-circuit. (check-in: c5f96a08 user: drh tags: trunk) | |
| 19:41 | Rename sqlite3ExprCodeAtInit() to sqlite3ExprCodeRunJustOnce(). Other changes to make the new code cleaner. Test cases added. (Closed-Leaf check-in: d7f18489 user: drh tags: do-not-factor-functions) | |

| 17:58 | Do not factor out constant functions into the initialization section at the end of the prepared statement, be cause if they throw an exception, it will abort the statement even if the function is never called. Better to put constant functions in an OP_Once block. (check-in: 97a18a5c user: drh tags: do-not-factor-functions) | |
| 16:46 | Support reporting of blob fields. (check-in: 724a4a84 user: dan tags: begin-concurrent-report) | |

| 11:50 | Apply the correct affinity transformations when pulling values off of the sorter index used for GROUP BY. Ticket [e0c2ad1aa8a9c691] (check-in: 101f7dea user: drh tags: trunk) | |
| 02:57 | The sqlite3ExprCodeFactorable() routine should make a copy of non-factorable expressions, as they might be coming from a DEFAULT or generated column in a table constraint. (check-in: a2d6f108 user: drh tags: trunk) | |
| 01:24 | Background work for experiments trying to enhance ANALYZE so that it runs off of samples of the entire index and does not need to read the entire index. (check-in: 29d1cc5c user: drh tags: approximate-analyze) | |
|
2020-03-09

| 18:04 | Report an error if the main, or any other, database encoding is modified by an external process (perhaps using the backup API) after the db has been opened. (check-in: 895bd20b user: dan tags: trunk) | |
| 16:13 | Change the sqlite3.pDfltColl (the default collating sequence for the database connection) so that it is the collating sequence appropriate for the database encoding, not the UTF8 collating sequence. This helps to ensure that the database encoding collation is always used, even for expressions that do not have an defined collating sequence. Ticket [1b8d7264567eb6fc]. (check-in: 4a585189 user: drh tags: trunk) | |
| 14:19 | When printing the OP_CollSeq opcode for EXPLAIN listings, include the text encoding with the name of the collating sequence. (check-in: eb5c1b77 user: drh tags: trunk) | |

|
2020-02-28
| ||
| 16:04 | The RTREE extension behaves as if data columns have type REAL, so we should actually declare them as REAL so that automatic indexes handle them correctly. Ticket [e63b4d1a65546532] (check-in: 85a9b6a9 user: drh tags: trunk) | |
|
2020-02-27
| ||
