| 20:12 | Remove an unreachable branch from the sqlite3_value_numeric_type() interface. (check-in: 5350229b user: drh tags: trunk) | |
| 16:47 | Avoid unnecessary no-op calls to applyNumericAffinity() for a small performance improvement. (check-in: 413d7287 user: drh tags: trunk) | |

| 21:35 | Try to fix harmless compiler warnings reported by Fortify. (check-in: e0fa6fdc user: drh tags: trunk) | |
| 18:37 | Improved comments on VDBE opcodes, for better documentation. No code or logic changes. (check-in: 2d32e487 user: drh tags: trunk) | |
| 18:01 | Add constraints (enforced only when SQLITE_DEBUG is enabled) on the use of OP_Next and OP_Prev. (check-in: 2230c74f user: drh tags: trunk) | |

| 23:23 | Improve the performance of the ANALYZE command by taking advantage of UNIQUE constraints on indices. (check-in: 114dcf33 user: drh tags: trunk) | |
| 22:41 | Fix a bug in the whereRangeSkipScanEst() procedure (added by check-in [d09ca6d5efad3e4cfa]) where it fails to consider the possibility of a ROWID column when computing the affinity of a table column. (check-in: 6aea2258 user: drh tags: trunk) | |
| 20:25 | Avoid trying to allocation zero bytes when analyzing a unique non-null index. (Closed-Leaf check-in: 85e2bade user: drh tags: faster-analyze) | |
| 19:54 | Avoid change tests when analyzing single-column unique indexes after getting past the initial NULL entries. (check-in: 4690e99c user: drh tags: faster-analyze) | |
| 12:39 | Add the readfile(FILENAME) and writefile(FILENAME,CONTENT) SQL functions to the command-line shell. (check-in: fb1048cb user: drh tags: trunk) | |
| 12:19 | Add support for hexadecimal integer literals in the parser. (check-in: f8f79f28 user: drh tags: trunk) | |
| 12:09 | In the command-line shell, in CSV output mode, terminate rows with CRNL but do not expand NL characters in data into CRNL. Provide the extra -newline command-line option and the extra argument to .separator to designate an alternative newline character sequence for CSV output. (check-in: 16c8ce10 user: drh tags: trunk) | |

| 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) | |
| 19:04 | Enhancements to the hex literal tests. (Closed-Leaf check-in: a3cc027f user: mistachkin tags: hex-literal) | |
| 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) | |
| 02:07 | Casting hex literals directly from string to float always results in a positive number. (check-in: 4b86ccdf user: drh tags: hex-literal) | |
| 01:59 | Reformatting a few test cases for clarity. (check-in: 7e1bbacb user: drh tags: hex-literal) | |
