| 23:23 | Improve the performance of the ANALYZE command by taking advantage of UNIQUE constraints on indices. (check-in: 114dcf3367 user: drh tags: trunk) | |
| 22:51 | Correct help text and make consistent use of snprintf. (check-in: 9c424a5c50 user: mistachkin tags: asciiMode) | |
| 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: 6aea2258dd user: drh tags: trunk) | |
| 22:33 | Update a shell test case. (check-in: b84008cb96 user: mistachkin tags: asciiMode) | |
| 22:20 | Fix typo in comment and update help text. (check-in: 289092bb64 user: mistachkin tags: asciiMode) | |
| 22:13 | Merge updates from trunk. (check-in: 8dc0cdf652 user: mistachkin tags: asciiMode) | |
| 20:25 | Avoid trying to allocation zero bytes when analyzing a unique non-null index. (Closed-Leaf check-in: 85e2badeeb 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: 4690e99c07 user: drh tags: faster-analyze) | |
| 16:43 | Merge recent trunk changes into the apple-osx branch. (check-in: 3810dc62d2 user: drh tags: apple-osx) | |
| 12:39 | Add the readfile(FILENAME) and writefile(FILENAME,CONTENT) SQL functions to the command-line shell. (check-in: fb1048cb2b user: drh tags: trunk) | |
| 12:19 | Add support for hexadecimal integer literals in the parser. (check-in: f8f79f2878 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: 16c8ce10e1 user: drh tags: trunk) | |

| 23:57 | Add experimental "costmult" logic. Only enabled when compiled with -DSQLITE_ENABLE_COSTMULT. (check-in: 729ece4088 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: 30033f9650 user: drh tags: faster-analyze) | |
| 19:04 | Enhancements to the hex literal tests. (Closed-Leaf check-in: a3cc027fa7 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: 3e1e79e133 user: drh tags: faster-analyze) | |
| 15:51 | Updated documentation on sqlite3_temp_directory. No changes to code. (check-in: e6225a7bf7 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: a5b383e077 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: 6c6f0de59b user: drh tags: hex-literal) | |
| 02:07 | Casting hex literals directly from string to float always results in a positive number. (check-in: 4b86ccdf4f user: drh tags: hex-literal) | |
| 01:59 | Reformatting a few test cases for clarity. (check-in: 7e1bbacb11 user: drh tags: hex-literal) | |
| 01:56 | Test cases for hex literals. (check-in: 19054339c4 user: drh tags: hex-literal) | |
| 01:26 | Add support for parsing C-style hexadecimal literals. (check-in: 34a1f38b7a 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: 48f40861db 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: 77f412caf0 user: drh tags: trunk) | |
