| 23:57 | Add experimental "costmult" logic. Only enabled when compiled with -DSQLITE_ENABLE_COSTMULT. (check-in: 729ece40 user: drh tags: trunk) | |
| 19:37 | Ugh. Consecutive UNIQUE index entries are only distinct if the index is on NOT NULL columns. So the previous version was not quite right. This check-in fixes the problem. (check-in: 30033f96 user: drh tags: faster-analyze) | |
| 19:31 | Add a snippet() function to fts5. (check-in: bdc58fd2 user: dan tags: fts5) | |

| 18:36 | Improve the performance of the ANALYZE command by taking advantage of the fact that every row of a UNIQUE index is distinct. (check-in: 3e1e79e1 user: drh tags: faster-analyze) | |
| 15:51 | Updated documentation on sqlite3_temp_directory. No changes to code. (check-in: e6225a7b user: drh tags: trunk) | |
| 14:52 | Remove a surplus function prototype. #ifdef code that is not used when hex integers are omitted at compile time. (check-in: a5b383e0 user: drh tags: hex-literal) | |
| 13:40 | Change the hex literal processing so that only the SQL parser understands hex literals. Casting and coercing string literals into numeric values does not understand hexadecimal integers. This preserves backwards compatibility. Also: Throw an error on any hex literal that is too big to fit into 64 bits. (check-in: 6c6f0de5 user: drh tags: hex-literal) | |

| 22:46 | When running ANALYZE, it is not necessary to check the right-most key column for changes since that column will always change if none of the previous columns have. (check-in: 48f40861 user: drh tags: trunk) | |
| 20:02 | Add the OP_ReopenIdx opcode that works like OP_OpenRead except that it becomes a no-op if the cursor is already open on the same index. Update the OR-optimization logic to make use of OP_ReopenIdx in order to avoid unnecessary cursor open requests sent to the B-Tree layer. (check-in: 77f412ca user: drh tags: trunk) | |
| 19:14 | The optimization of check-in [b67a6e33f2] does not work (it generates incorrect VDBE code) if an OR term is AND-ed with a constant expression. So back that optimization out and add a test case to make sure it does not get added back in. (check-in: eed754fe user: drh tags: trunk) | |
| 16:00 | Fix the index name for the shadow tables in the spellfix1 extension so that multiple instances of the spellfix1 virtual table can each have their own index. (check-in: 438c348a user: drh tags: trunk) | |
| 15:33 | Correction: The maximum SQLITE_MAX_ATTACHED value to avoid overflowing a signed 8-bit integer is 125, not 127. (check-in: 48e37802 user: drh tags: trunk) | |
| 14:58 | Enhance the sqlite_stat1.stat parsing to allow additional text parameters at the end. Unrecognized parameters are silently ignored. (check-in: ca2a5a2c user: drh tags: trunk) | |
| 14:42 | Expire prepared statements after running ANALYZE. (check-in: b083a961 user: drh tags: trunk) | |

Today is a sad day. But the warnings from GCC grow increasingly verbose and irksome with each new release and so something had to be done. (check-in: df056798 user: drh tags: trunk) | |

Earlier versions did not access this part of the file in order to avoid triggering an assert in os_unix.c. But the assert() has since been removed.
