| 03:38 | Do not record a page-size change if the attempt to change the page size failed due to an OOM error. check-in: 4d4fb197 user: drh tags: trunk | |
| 03:16 | Add the sqlite3_memdebug_title_count global variable, used during debugging to count the number of invocations of test_memdebug_settitle. By examining this variable in the debugger after a segfault, one can then set a breakpoint on test_memdebug_settitle that will fire just before the problem. check-in: 27e3ca3e user: drh tags: trunk | |
| 02:00 | Fix a couple of typos in comments. No changes to code. check-in: a758465e user: mistachkin tags: trunk | |
| 01:35 | Query planner heuristic update: When doing a full table scan on a table that has an equality constraint on an unindexed column, do not allow the estimated number of output rows to be greater than half the total number of rows in the table. check-in: 73954f93 user: drh tags: trunk | |

| 19:05 | Avoid ever running a checkpoint in ota mode. check-in: 9ae44447 user: dan tags: ota-update | |
| 18:05 | Fix showwal.c so that it works with 64KiB pages. check-in: fc4f7c11 user: dan tags: ota-update | |
| 11:03 | Avoid calling sqlite3OsFetch() on a file-handle for which the xFetch method is NULL. check-in: 071f7f2d user: dan tags: ota-update | |
|

| ||
| 19:30 | Split part of "PRAGMA ota_mode" off into "PRAGMA pager_ota_mode". This allows some specialized custom VFS implementations to intercept and implement the expected pager-related effects of this pragma. check-in: 209f672e user: dan tags: ota-update | |
| 08:25 | Add a command line program that uses the extension. This serves as example code and is also useful for performance testing. check-in: ffa1524e user: dan tags: ota-update | |
|
2014-09-02

| 23:06 | Update comments in the ANALYZE command that describe how the Stat4Accum objecct is passed around within the VDBE. No changes to functional code. check-in: 9779c7a9 user: drh tags: trunk | |
| 22:34 | Avoid a confusing (though correct) argument to the sqlite3_result_blob() function in the implementation of ANALYZE. check-in: 4cae93f8 user: drh tags: trunk | |
| 19:29 | For sqlite3_win32_is_nt(), assume WinRT is NT-based and revise #ifdef ordering to prefer the ANSI version of GetVersionEx, when available. check-in: be0a0372 user: mistachkin tags: trunk | |
| 18:21 | Tweak the documentation for SQLITE_LIMIT_WORKER_THREADS. No changes to executable code. check-in: 672e7387 user: drh tags: trunk | |
| 17:36 | Add support for using separate worker threads to speed large sorts. The SQLITE_MAX_WORKER_THREADS and SQLITE_DEFAULT_WORKER_THREADS compile-time options and the SQLITE_LIMIT_WORKER_THREADS argument to sqlite3_limit() and the "PRAGMA threads=N" pragma are added. check-in: b1c0f0bc user: drh tags: trunk | |
| 13:37 | Attempt to make the xDelete method of the unix VFS more robust on VxWorks. check-in: b0f6b91f user: drh tags: trunk | |

| 19:06 | Disable worker threads when SQLITE_THREADSAFE=0. Set the default compile-time maximum number of worker threads to 8 and honor the SQLITE_DEFAULT_WORKER_THREADS compile-time constant (which defaults to 0). Closed-Leaf check-in: 33fa0410 user: drh tags: threads | |
| 18:06 | Fix the speedtest1.c test program to set the worker thread count using the threads pragma. check-in: 2ab4b5ad user: drh tags: threads | |
| 16:20 | Add SQLITE_LIMIT_WORKER_THREADS for controlling the maximum number of worker threads. check-in: 1b598c68 user: drh tags: threads | |
| 14:40 | Merge recent performance enhancements from trunk onto the threads branch. check-in: 35c44a3c user: drh tags: threads | |
| 14:20 | Not a fault after all, rather a testing mistake. Move this change back to trunk. Was: Avoid an unnecessary OP_Move operation for expression subqueries. check-in: 2a74129a user: drh tags: trunk | |
| 12:29 | Contains a fault. Was: Avoid an unnecessary OP_Move operation for expression subqueries. Closed-Leaf check-in: 462f42af user: drh tags: mistake | |

| 19:38 | Improved WHERETRACE messages for the estimated output row reductions from range scans. check-in: fdd478bb user: drh tags: trunk | |
| 17:30 | Fix a problem causing an inaccurate stat4-based estimate for the number of rows visited by a range scan. check-in: a9daf3ac user: drh tags: trunk | |
| 17:20 | Add a testcase() macro to help verfity the row estimation logic. Closed-Leaf check-in: 6ba60952 user: drh tags: stat4-experimental | |
| 16:01 | Fix a problem causing an inaccurate stat4-based estimate for the number of rows visited by a range scan. check-in: 052d89b5 user: dan tags: stat4-experimental | |
| 13:42 | Fix a formatting error ("%d" needed in place of "%g") on a WHERETRACE macro inside of the query planner. This fix applies to debugging logic only. check-in: c931ca2b user: drh tags: trunk | |

| 23:18 | Refactor the sqlite3PcacheFetch() routine into three separate routines, which are significantly faster overall and about 100 bytes smaller in size as well. check-in: bdb6e497 user: drh tags: trunk | |
| 17:53 | Add a VDBE synopsis comment for clarification. check-in: 029a6dc7 user: mistachkin tags: trunk | |
| 17:48 | Add a missing ticket number to a comment in index7.test. check-in: d8b1c433 user: dan tags: trunk | |
| 17:37 | When determining whether or not a partial index is usable, do not assume that the cursor number assigned to each table in the query is the same as its index in the FROM clause. Fix for ticket [98d973b8f5]. check-in: fcebca16 user: dan tags: trunk | |
| 14:14 | In the sqlite3_context object, keep a pointer to the result value rather than storing the result value in the sqlite3_context object and using memcpy() to move the value back into its register after the function returns. This runs faster and saves over 500 bytes of code space. check-in: 6c1ee3e3 user: drh tags: trunk | |
| 03:28 | Factor out the exception paths from sqlite3ValueToText() into a separate function so that the main routine is much faster for the common case of no required type or encoding conversions. check-in: 1624916c user: drh tags: trunk | |
| 00:50 | Performance enhancement in sqlite3VdbeMemNulTerminate(). check-in: f94cacc3 user: drh tags: trunk | |
|
2014-08-26
| ||
| 15:06 | Change the page cache so that a new sqlite3_pcache object is allocated as soon as the page cache is opened, not delayed until the first fetch request. This give a noticable performance boost. The interface between pager and the page cache has changed slightly, which might break ZIPVFS. check-in: f1f94a97 user: drh tags: trunk | |
|
2014-08-25
| ||
| 23:44 | Remove the SQLITE_CONFIG_WORKER_THREADS configuration parameter. The number of worker threads in the sorter is now determined only by the PRAGMA threads=N setting. check-in: e3305d4b user: drh tags: threads | |
| 22:43 | Merge the CAST operator enhancements from trunk. check-in: 6c8f86e4 user: drh tags: threads | |
| 22:37 | Add an assert() and five testcase() macros to the OP_Cast opcode implementation to help verify that it is fully tested. check-in: af364cce user: drh tags: trunk | |
| 21:11 | Minor changes to the CAST logic to make it more testable. check-in: 1ad70ec5 user: drh tags: trunk | |
| 20:21 | Test cases added for using unary "+" and CAST operators on the RHS of range constraints and verifying that STAT3/4 can use those constraints. check-in: 42505e5a user: drh tags: trunk | |
| 20:11 | Allow CAST expressions and unary "+" operators to be used in the DEFAULT argument of an ALTER TABLE ADD COLUMN and to be understand on the RHS of range constraints interpreted by STAT3/4. This involves a rewrite of the implementation of the CAST operator. check-in: 91d8a8d0 user: drh tags: trunk | |
| 18:29 | In cases where stat4 data is available but cannot be used because the rhs of a range constraint is too complex a expression, fall back to using the default estimates for number of rows scanned. check-in: e06dc6f0 user: dan tags: trunk | |
| 15:13 | Query or change the maximum number of worker threads allowed on each database connection separately using the "PRAGMA threads" command. check-in: 29c5e8a7 user: drh tags: threads | |
| 13:27 | Merge the recent performance enhancements implemented on trunk into the threads branch. check-in: dfdc900f user: drh tags: threads | |
| 11:33 | Remove the pager_lookup() function since it is redundant with sqlite3PagerLookup(). check-in: 54164ce4 user: drh tags: trunk | |
| 11:20 | Change the name of the VdbeMemRelease() macro to VdbeMemReleaseExtern() to more accurately reflect what it does. Performance enhancement to the sqlite3VdbeMemRelease() function. check-in: 3ca5846d user: drh tags: trunk | |
|
2014-08-24
| ||
| 02:53 | The sqlite3VdbeChangeEncoding() routine goes about 3x faster if the sqlite3VdbeMemTranslate() subroutine is not inlined. check-in: 0c7e1b87 user: drh tags: trunk | |
| 01:32 | Patch the sqlite3PagerWrite() method in the Pager to run a bit faster. check-in: c63311e2 user: drh tags: trunk | |

| 23:15 | Faster implementation of pcache1Fetch() check-in: 0371cc3b user: drh tags: trunk | |
| 20:25 | Faster implementation of the sqlite3ApiExit() routine. check-in: bd41d394 user: drh tags: trunk | |
| 19:42 | Another memory allocator performance optimization. check-in: 6da6f46d user: drh tags: trunk | |
| 19:08 | Fix a variable-declaration after code problem in btree.c. Harmless in GCC and CLANG but unacceptable for MSVC. check-in: 45abd5c0 user: drh tags: trunk | |
| 19:04 | Changes to sqlite3ScratchMalloc() that make the entire memory allocation interface a little faster and about 100 bytes smaller. check-in: f83daa16 user: drh tags: trunk | |
| 18:17 | Make the implementation of the sqlite3_aggregate_context() interface faster for second an subsequent invocations. This helps all aggregate functions to perform better. check-in: 802148f3 user: drh tags: trunk | |
| 17:41 | Improved performance in the type handling of arithmetic operators in the VDBE. check-in: 0c0a6039 user: drh tags: trunk | |
| 17:21 | Performance optimization in the applyAffinity() logic inside the VDBE. check-in: 25f2246b user: drh tags: trunk | |
