| 18:54 | Optimizations to the OS sub-type checking in the Win32 VFS. (check-in: 1e5489faff user: mistachkin tags: trunk) | |
| 18:14 | Add a missing call to "test_sqlite3_log" to multiplex.test. (check-in: 0708f9df23 user: dan tags: trunk) | |
| 17:35 | Fix a leaked database handle in pager2.test. (check-in: 47457b0488 user: dan tags: trunk) | |
| 15:44 | Deactivate the DISTINCT in a SELECT on the right-hand side of an IN operator, since it should not make any difference in the output but dues consume extra memory and CPU time. (check-in: f4cb53651b user: drh tags: trunk) | |

| 23:11 | Re-integrate the recent changes from the 'winMutex' branch back into the Win32 mutex subsystem. (check-in: 5360ecb0b8 user: mistachkin tags: trunk) | |
| 21:10 | Add three new static mutexes for use by the application. This is a partial import of changes from the threads branch. (check-in: 3aad01960f user: drh tags: trunk) | |
| 15:43 | Add the "eForce" parameter to the sqlite3_multiplex_shutdown() entry point in test_multiplex.c. Shutdown is forced if true. Shutdown is not done if there are pending database connections and eForce is false, but an error log entry is made instead. (check-in: c7303d0139 user: drh tags: trunk) | |
| 13:56 | Ensure that the correct number of columns in a UNIQUE index are checked for uniqueness, regardless of whether or not the original table has a ROWID or if the columns are NOT NULL, etc. Ticket [9a6daf340df99ba93c]. (check-in: 6b785e92f2 user: drh tags: trunk) | |

| 19:54 | Enhancements and updates to the Win32 mutex subsystem. (check-in: ca9868cdae user: mistachkin tags: trunk) | |
| 18:03 | Merge updates from trunk. (Closed-Leaf check-in: 08c9a4ea63 user: mistachkin tags: winMutex) | |
| 14:09 | Add the SQLITE_TESTCTRL_ISINIT file control. (check-in: 8b651d4d6c user: drh tags: trunk) | |
| 11:54 | Have calls to the xFilter() method of rtree virtual tables ensure that cursor is initialized before proceeding. Fix for [d2889096e7bdeac]. (check-in: 8cc41b0bf3 user: dan tags: trunk) | |
| 05:49 | Enhancements and updates to the Win32 mutex subsystem. (check-in: 18984c3210 user: mistachkin tags: winMutex) | |

| 20:12 | Remove an unreachable branch from the sqlite3_value_numeric_type() interface. (check-in: 5350229b52 user: drh tags: trunk) | |
| 16:47 | Avoid unnecessary no-op calls to applyNumericAffinity() for a small performance improvement. (check-in: 413d728797 user: drh tags: trunk) | |
|

| ||
| 21:35 | Try to fix harmless compiler warnings reported by Fortify. (check-in: e0fa6fdc14 user: drh tags: trunk) | |
| 18:37 | Improved comments on VDBE opcodes, for better documentation. No code or logic changes. (check-in: 2d32e4876e 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: 2230c74f1e user: drh tags: trunk) | |
|

| 23:23 | Improve the performance of the ANALYZE command by taking advantage of UNIQUE constraints on indices. (check-in: 114dcf3367 user: drh tags: trunk) | |
| 22:41 | 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) | |
| 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) | |
| 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) | |
| 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: eed754fe93 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: 438c348a40 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: 48e3780295 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: ca2a5a2c77 user: drh tags: trunk) | |
| 14:42 | Expire prepared statements after running ANALYZE. (check-in: b083a961f8 user: drh tags: trunk) | |
| 12:05 | Enhance the comment on whereLoopAddBtree(). No changes to code. (check-in: b22dd165da user: drh tags: trunk) | |
| 00:40 | For the OR-optimization, avoid generating OP_OpenRead opcodes that reopen exactly the same index. (check-in: b67a6e33f2 user: drh tags: trunk) | |
|

| 20:07 | Limit the maximum SQLITE_MAX_ATTACHED to 127, since a signed character is sometimes used to store the database index. (check-in: f1c76c7c4c user: drh tags: trunk) | |
| 15:44 | Allow the SQLITE_MAX_ATTACHED compile-time option to be larger than 62. The default limit on the number of attached databases remains 10. (check-in: 1a817ae2f3 user: drh tags: trunk) | |
|
2014-07-19
| ||
| 17:57 | Update the sqlite3_stmt_busy() function so that it correctly returns true for "ROLLBACK" statements that have been stepped but not yet reset. (check-in: 61cee3c067 user: dan tags: trunk) | |
| 17:49 | Fix harmless compiler warnings in the showdb and showwal tools and in the unicode tokenizer of FTS3. (check-in: 574cc8eb14 user: drh tags: trunk) | |
| 15:44 | Fix some harmess compiler warnings in the FTS3 Unicode module. (Closed-Leaf check-in: c01caea5d6 user: mistachkin tags: toolWarnings) | |
| 15:40 | Fix warnings related to having a 64-bit size_t. (check-in: 29ac9336db user: mistachkin tags: toolWarnings) | |
