| 17:36 | Change an OP_SCopy into an OP_Copy in a case where the destination might be used after the source has changed. (check-in: c0fa0c0e2d user: drh tags: trunk) | |
| 16:48 | Change the "explain_i" tcl test command so that xterm color codes are only added if the output is actually a terminal. (check-in: 559835e54e user: dan tags: trunk) | |
| 15:13 | Fix a harmless compiler warning. (check-in: d7f6837e69 user: drh tags: experimental) | |

| 14:20 | Fix a segfault that can occur following an OOM error. (check-in: 7fdd378d54 user: dan tags: trunk) | |
| 00:12 | Change the MEM_Dyn flag so that it means that Mem.xDel exists and must be used to free the string or blob. Add tighter invariant checks on Mem. (check-in: e3f6c61e03 user: drh tags: trunk) | |

| 19:45 | Merge trunk changes. (check-in: 9c1747b5de user: dan tags: experimental) | |
| 19:44 | Remove the vdbeRecordCompareLargeHeader function. Fix some other details. (check-in: 3861e85310 user: dan tags: experimental) | |
| 18:13 | Change the MEM_Dyn flag so that it means that Mem.xDel exists and must be used to free the string or blob. Add tighter invariant checks on Mem. (Closed-Leaf check-in: 44e1c33767 user: drh tags: enhanced-mem-check) | |
| 16:24 | Factor the Mem invariant checker into a separate procedure (rather than a macro) so that it can be more easily extended. (check-in: 354699d50e user: drh tags: enhanced-mem-check) | |
| 14:45 | Add extra assert() statements trying to catch a Mem object in an inconsistent state. (check-in: 4aeb3ae435 user: drh tags: enhanced-mem-check) | |
|

| 20:47 | In the command-line shell add the (undocumented and unsupported) ".eqp" command and -eqp command-line option, to cause EXPLAIN QUERY PLAN to be run on each SQL statement as it is evaluated. Intended use is for analysis of the query planner. (check-in: e6ecf73376 user: drh tags: trunk) | |
| 19:37 | Provide an #ifdef in shell.c to work around issues when cross-compiling from Ubuntu to windows. (check-in: 0a3579d9b9 user: drh tags: trunk) | |
| 18:39 | Update some test cases that deal with corrupt databases. (check-in: 3a09f5605a user: dan tags: experimental) | |
| 09:48 | Minor tweak to vdbeRecordCompareInt(). (check-in: 284bde0ee2 user: dan tags: experimental) | |

| 20:52 | Merge in latest trunk changes. (check-in: 8f30b09518 user: dan tags: experimental) | |
| 20:44 | Further changes to sqlite3VdbeRecordCompare(). (check-in: 5708937400 user: dan tags: experimental) | |
| 15:11 | A better way of handling the USE_SYSTEM_SQLITE #define in shell.c. (check-in: 51ce713c6e user: drh tags: trunk) | |
| 15:04 | Add #defines to the command-line shell source code (shell.c) so that it can be imported directly into other projects (ex: Fossil) and used without editing. (check-in: a669040023 user: drh tags: trunk) | |
| 05:47 | Merge updates from trunk. (check-in: ed0bfcfadc user: mistachkin tags: winIoRetry) | |
|
2014-02-26
| ||
| 21:35 | More efficient removal of duplicates in recursive queries using the UNION compound operator. (check-in: 06c2db875e user: drh tags: trunk) | |
| 19:05 | Only run the OP_OpenRead opcodes for a correlated subquery once, on the initial iteration. Keep the cursor open for subsequent runs. This was suppose to be a performance enhancement, but it is difficult to come up with a query where is makes a significant difference. Hence, the change is getting parked in a branch. (Leaf check-in: 3ad687b7aa user: drh tags: open-only-once) | |
| 13:53 | In the command-line shell for CSV import, if the lines are \r\n terminated and the last field is blank, make sure an empty string and not a "\r" string is imported. (check-in: 9c2e7612cd user: drh tags: trunk) | |
| 02:26 | Improved handling of constants and especially constant functions in the ORDER BY clause of a query. Do not optimize out "ORDER BY random()". Fix for ticket [65bdeb9739605cc2296]. (check-in: dca1945aeb user: drh tags: trunk) | |

| 21:55 | Do not allow temporary registers to be in use across an OP_Yield within a co-routine. Fix for ticket [8c63ff0eca81a9132d8]. (check-in: 97a8c9733c user: drh tags: trunk) | |
| 21:01 | Attempt to speed up sqlite3VdbeRecordCompare() by various means. This code is in an interim state. (check-in: 85206e0bba user: dan tags: experimental) | |
| 19:38 | Make sure temporary registers used within a co-routine are not also used outside of that co-routine, in order to prevent concurrent use of the same register for two different things. Ticket [8c63ff0eca81a9132d8] (Closed-Leaf check-in: cc5eda5422 user: drh tags: tkt-8c63ff0eca) | |
| 18:12 | Also adjust the order of files in the amalgamation to ensure that _FILE_OFFSET_BITS is defined before any #include, for QNX. (check-in: 23001a85cd user: drh tags: trunk) | |
| 14:52 | QNX requires that _FILE_OFFSET_BITS be set prior to any system #include. (check-in: 953cdd6ada user: drh tags: trunk) | |

| 21:42 | Fix several small style/consistency issues with the previous check-in. (check-in: 2477b3a294 user: mistachkin tags: trunk) | |
| 21:23 | Merge updates from trunk. (Closed-Leaf check-in: 854d410ad3 user: mistachkin tags: cygDlOpen) | |
| 21:20 | Enhance testing support for the Win32 VFS dynamic extension loading facilities. (check-in: 53081e7202 user: mistachkin tags: trunk) | |
| 19:49 | Close some stray connections in walro.test. (check-in: d6746cabaa user: dan tags: trunk) | |
| 19:07 | In memsys5, initialize new allocations to non-zero bytes. Change the content of freed allocations to prevent use after free. These changes in SQLITE_DEBUG only. (check-in: ba5f0a5599 user: drh tags: trunk) | |
| 14:24 | Remove an unused variable from the VDBE_PROFILE compile-time option. Keep the opcode count in an u32 instead of an int. (check-in: 4df0ac9023 user: drh tags: trunk) | |
|

| 10:48 | Merge updates from trunk. (check-in: 09cf240a7f user: mistachkin tags: winHdr) | |
| 05:44 | Better loadable extension handling in the Win32 VFS when compiled for Cygwin. (check-in: 6676475c47 user: mistachkin tags: cygDlOpen) | |
|
2014-02-20
| ||
| 19:42 | Fix the text of a comment used to generate VDBE opcode documentation so that it omits symbols that can be mistaken for a hyperlink by the parser. (check-in: b46d4e8923 user: drh tags: trunk) | |
| 19:32 | Fix a harmless shadowed-variable warning. (check-in: 824029090d user: drh tags: trunk) | |
| 19:23 | Make sure that the difference between two string pointers is passed into sqlite3_mprintf() as type "int". (check-in: d5d973fedc user: drh tags: trunk) | |
|
2014-02-19
| ||
| 19:14 | Add the VdbeCoverageNeverTaken() macro, and comments that better describe how the VDBE branch coverage measurement works. Add some tags to provide 100% VDBE branch coverage. (check-in: c1e94169dd user: drh tags: trunk) | |
| 14:20 | Add the SQLITE_NOTNULL P5 code for comparison operations - really a composite of SQLITE_NULLEQ and SQLITE_JUMPIFNULL. This flag indicates that NULL operands are not possible and raises and assert() if NULL operands are seen. Also omit an unnecessary scan of the sqlite_sequence table when writing into an AUTOINCREMENT table. (check-in: d2c047f304 user: drh tags: trunk) | |
| 01:31 | Make sure a multi-row VALUES clause works correctly in a compound SELECT. (check-in: 85b355cfb4 user: drh tags: trunk) | |
| 00:53 | Tweaks in support of VDBE branch test coverage. (check-in: b978256469 user: drh tags: trunk) | |
|
2014-02-18
| ||
| 11:31 | Fix VDBE branch accounting on comparison operators. (check-in: b287520c92 user: drh tags: trunk) | |
| 05:18 | Enhance the Win32 VFS I/O retry logic. (check-in: adba783c70 user: mistachkin tags: winIoRetry) | |
| 03:07 | Add VdbeCoverage() and VdbeCoverageIf() macros for improved VDBE coverage testing. (check-in: b92d31a97d user: drh tags: trunk) | |
| 01:07 | Improvements to "NOT IN (SELECT ...)" processing. Only test for NULL values on the RHS on the first iteration, then remember the result. There has been logic to do this for year, but it didn't work right and ended up repeating the NULL test on every iteration. This inefficiency was found using the VDBE coverage testing tools. (check-in: 915f6f1c7a user: drh tags: trunk) | |
