| 18:19 | Remove 'const' from a variable that might actually be written when an OOM error occurs. Also, fix a couple MSVC/Win32 compiler warnings. (check-in: 3035dc1c73 user: mistachkin tags: trunk) | |
| 13:41 | Remove unused parameters from internal routines in vdbesort.c. This is an additional simplification made possible by recent optimizations. (check-in: a1f3aeeb09 user: drh tags: trunk) | |
| 13:23 | Remove code from vdbesort.c that was made unreachable by the recent sqlite3VdbeRecordUnpack() optimizations. (check-in: 607aba6cd7 user: drh tags: trunk) | |
|
2011-09-13
| ||
| 19:09 | Merge the latest trunk changes into the stat3-trunk branch. (check-in: 11ca4ed8bf user: drh tags: stat3-trunk) | |
| 19:08 | Allocate the correct size for the output buffer in fts3DoclistOrMerge(). Fix for [56be976859]. (check-in: 07788c0f7f user: dan tags: trunk) | |
|
2011-09-11

| 01:11 | Improve the testability of the merge-sort logic. (check-in: b5179baf87 user: drh tags: trunk) | |
|
2011-09-03
| ||
| 17:07 | Performance improvements to the external merge-sorter. Keep content on an in-memory linked lists rather than an ephemeral table prior to spilling to disk. Use the external merge-sorter to implement ORDER BY and GROUP BY in addition to CREATE INDEX. (check-in: 4c43e8b2d2 user: drh tags: trunk) | |
| 16:42 | Simplification and performance tweaks in vdbeSorterMerge(). (Closed-Leaf check-in: 99e34bdce4 user: drh tags: merge-sort) | |
| 14:36 | Reduce the number of VdbeRecordUnpack() calls made in vdbesort.c. (check-in: 666c2c3cff user: dan tags: merge-sort) | |
| 00:17 | The build works again with -DSQLITE_OMIT_MERGE_SORT. The merge-sorter now avoids spilling to disk (letting the in-memory linked list grow without bound) if PRAGMA temp_store=3. (check-in: 68e26c4487 user: drh tags: merge-sort) | |
|
2011-09-02
| ||
| 21:42 | Remove some dead code. Fix a faulty assert(). Improve some variable names. (check-in: a9a64592cf user: drh tags: merge-sort) | |
| 18:03 | Combine two malloc calls in vdbesort.c. (check-in: cf48ad8353 user: dan tags: merge-sort) | |
| 15:41 | Reduce the number of malloc() calls made when creating an index on more than 2 columns. (check-in: 065b0c9858 user: dan tags: merge-sort) | |
| 15:08 | Remove unused local variable. (check-in: 61bda876af user: mistachkin tags: trunk) | |
| 11:45 | If all data being sorted fits in memory, avoid writing any data out to temporary files in vdbesort.c. (check-in: 71075673c6 user: dan tags: merge-sort) | |
| 10:31 | Instead of a temporary b-tree, use a linked-list and merge-sort to sort records in main memory in vdbesort.c. (check-in: 7769fb988d user: dan tags: merge-sort) | |
|
2011-09-01
| ||
| 16:01 | Use OP_SorterOpen instead of OP_OpenEphemeral to implement GROUP BY. (check-in: ebf819aaa5 user: drh tags: merge-sort) | |

|
2011-08-31
| ||
| 23:57 | Avoid using uninitialized variables after failures in the merge sort code. (check-in: 2869ed2829 user: drh tags: trunk) | |
| 21:01 | Formerly, we enabled fdatasync() on linux only. But now we learn that fdatasync() is not supported on Android. So we disable fdatasync() on Linux too. It can be reenabled at compile-time for those who really need it. (check-in: 70b5b30956 user: drh tags: trunk) | |
| 20:47 | Add the SQLITE_MAX_SCHEMA_RETRY compile-time option to the set of options understood by "PRAGMA compile_options;" and by the "sqlite_compileoption_used()" function. (check-in: 1b124af40a user: drh tags: trunk) | |
| 19:40 | The server1.test script should only run if mutexes are functional. Fix to the #ifdef change of check-in [9e6a4c1473]. (check-in: 6489848590 user: drh tags: trunk) | |
| 18:35 | Always include the unixShm.id field, even when not debugging. (check-in: 0780347620 user: drh tags: trunk) | |
| 18:04 | Only create the sqlite3OSTrace global variable if compiling with SQLITE_TEST. (check-in: 9e6a4c1473 user: drh tags: trunk) | |
| 17:46 | Backslash escaping is not working right in tostr.awk on the latest ubuntu. The easiest fix is to simply not use any backslashes in the spaceanal.tcl script. (check-in: df55006665 user: drh tags: trunk) | |
| 13:27 | Add checks to make sure cells in corrupt database files do not overflow a page when doing autovacuum. Problem detected by valgrind. (check-in: d0b347b412 user: drh tags: trunk) | |
|
2011-08-30
| ||
| 19:52 | Enable the thread test logic to work with the SQLITE_HAS_CODEC compile-time option. (check-in: 20ddfb4780 user: drh tags: trunk) | |
| 01:29 | Change the build process so that it does not require the unix "sort" command. This avoids confusion between ms-sort and mingw-sort on windows systems. (check-in: f1bd5bbae5 user: drh tags: trunk) | |
| 01:23 | Make sure SQLITE_FCNTL_SIZE_HINT a no-op if the chunk size is not greater than zero. (check-in: 88b763e8d7 user: mistachkin tags: trunk) | |
| 00:58 | Fix a total unimportant file descriptor leak in lemon. This is to silence warning messages. (check-in: e95cf2c576 user: drh tags: trunk) | |
| 00:53 | Fix a buffer overrun in test logic. No impact on the core SQLite. (check-in: 49cd60e38b user: drh tags: trunk) | |
|
2011-08-29
| ||
| 18:24 | Fix a broken assert() statement in select.c. (check-in: ad78ef2b3a user: dan tags: trunk) | |
| 11:56 | Back out [05c9832e5f6eb] since it was causing a performance regression with no obvious benefit. (check-in: 639cc85a91 user: drh tags: trunk) | |
| 03:08 | Merge performance enhancements into trunk. (check-in: 5a00d24b27 user: drh tags: trunk) | |
| 02:49 | About a 1% overall performance improvement by using a macro to avoid no-op calls to sqlite3MemReleaseExternal(). (Closed-Leaf check-in: ff71d20a9e user: drh tags: experimental) | |
| 02:16 | Small performance improvement to OP_Column. (check-in: b6b73a747a user: drh tags: experimental) | |
|
2011-08-28
| ||
| 02:15 | About a 3% improvement in the performance of OP_Column. (check-in: edff9d4a99 user: drh tags: experimental) | |
| 00:19 | Correctly display P4_ADVANCE values on opcode traces. Mark an always-taken branch in OP_Column as such. (check-in: 087dc96086 user: drh tags: experimental) | |
|
2011-08-27
| ||
| 18:48 | Experimental changes to improve the performance of OP_Next. (check-in: 1a24984525 user: dan tags: experimental) | |

| 20:55 | Fix several harmless compiler warnings and a documentation bug. (check-in: 5454d0fe22 user: drh tags: trunk) | |
| 19:20 | Merge the latest trunk changes into the sessions branch. (check-in: eb036d6f81 user: drh tags: sessions) | |
| 19:18 | Merge the latest trunk changes into the apple-osx branch. (check-in: 55af80035f user: drh tags: apple-osx) | |
| 13:16 | Merge the stat3-enhancement branch with trunk, but keep the resulting merge in a separate branch for now. (check-in: 63f2c7859f user: drh tags: stat3-trunk) | |
| 11:25 | Update compiler error message regarding the choice of memory allocator defines. (check-in: 1dada51582 user: mistachkin tags: trunk) | |
| 11:18 | Merge Win32 native heap support into trunk. (check-in: 5238a74987 user: mistachkin tags: trunk) | |
| 05:40 | In the MSVC makefile, allow symbols to be enabled without NDEBUG defined. Also, for the win32lock test, make sure the database is closed prior to shutdown. (Closed-Leaf check-in: 5ed7633d41 user: mistachkin tags: winNativeHeap) | |
| 01:45 | Disable checking the winMemData structure signature when compiled with NDEBUG. (check-in: 50edc2f914 user: mistachkin tags: winNativeHeap) | |
| 01:32 | Allow the Win32 native heap flags to be overridden at compile-time. (check-in: 1c2ecec8e7 user: mistachkin tags: winNativeHeap) | |
|
2011-08-25
| ||
| 04:09 | Add comments for the various debug levels. When debugging, disable optimizations. Prevent the win32lock tests from spinning forever. (check-in: 401859236b user: mistachkin tags: winNativeHeap) | |
| 02:02 | In the MSVC makefile, support several levels of debugging, each one building on the previous. Also, add comment about the SQLITE_WIN32_MALLOC_VALIDATE macro. (check-in: 4257e9b7ca user: mistachkin tags: winNativeHeap) | |
| 01:16 | Make sure that SQLITE_FCNTL_SIZE_HINT on Windows does not shrink the file. (check-in: d4f6437f8d user: mistachkin tags: winNativeHeap) | |
|
2011-08-24
| ||
| 17:42 | Add error logging to native Win32 heap support. (check-in: 7fca5a284c user: mistachkin tags: winNativeHeap) | |
| 16:13 | Experimental work to allow SQLite to use the native Win32 heap API. (check-in: bf3d0ab538 user: mistachkin tags: winNativeHeap) | |
| 15:18 | Updates to the sqlite3_mem_methods documentation. (check-in: 988998fe7b user: drh tags: trunk) | |
| 15:12 | Fix some harmless compiler warnings. (check-in: 46f5a68bfa user: drh tags: trunk) | |
| 01:25 | Changes to test_quota.c to make quota groups persistent even after files are closed. Files remain a part of the quota group until they are deleted. (check-in: 04111ce980 user: drh tags: trunk) | |
|
2011-08-23
| ||
| 23:41 | Simplifications to the SQLITE_PAGECACHE_BLOCKALLOC logic. Reduce the number of difficult-to-reach branches. (check-in: d5d835fe83 user: drh tags: trunk) | |
| 20:11 | If the application-defined openDirectory() function returns SQLITE_CANTOPEN, then silently ignore the error. This allows the chromium sandbox to disallow opening of directories without causing errors. (check-in: 880b51150a user: drh tags: trunk) | |
| 19:46 | Change the way the "crash" VFS (test6.c) handles SQLITE_FCNTL_SIZE_HINT. (check-in: 40dd8a60be user: dan tags: trunk) | |
| 16:41 | Have the "crash" VFS used by the tcl tests (test6.c) handle SQLITE_FCNTL_SIZE_HINT internally, instead of passing it directly through to the underlying VFS. This is important if the crash VFS is simulating non-default device characteristics such as SQLITE_DEVCAP_SEQUENTIAL or ATOMIC. (check-in: fac8bc8f34 user: dan tags: trunk) | |
| 13:27 | Ifdef out routines in pcache1.c that are used only when SQLITE_PAGECACHE_BLOCKALLOC is defined. (check-in: 0da292da3b user: drh tags: trunk) | |
| 12:50 | Merge the PAGECACHE_BLOCKALLOC changes into trunk. (check-in: 768c1846d4 user: drh tags: trunk) | |
| 11:47 | When copying a rollback mode database over a WAL database using the backup API, leave the destination database in WAL mode (instead of switching it to rollback mode). Fix for [af95b8c609]. (check-in: 35e6ac18e3 user: dan tags: trunk) | |
| 05:10 | Change to test instrumentation of os_unix.c: Regard IO errors that occur within SQLITE_FCNTL_SIZE_HINT requests as benign. (This check-in was intended for trunk and went onto the branch accidentally.) (Closed-Leaf check-in: ca47da2a1f user: dan tags: pager-blockalloc) | |
| 00:01 | Remove a branch that is always true. (check-in: a65681926d user: drh tags: trunk) | |
|
2011-08-22
| ||
| 20:33 | Remove an unreachable branch in the FK code. (check-in: 6c227cc853 user: drh tags: trunk) | |
| 14:55 | Modify test cases so that veryquick.test passes with PAGECACHE_BLOCKALLOC defined. (check-in: c61000705b user: dan tags: pager-blockalloc) | |
| 09:54 | Fix for [b1d3a2e531]. (check-in: 3f3acee465 user: dan tags: trunk) | |
|
2011-08-19
| ||
| 18:15 | Experimental change: If SQLITE_PAGECACHE_BLOCKALLOC is defined, instead of allocating pages one at a time, allocate blocks of between 15 and 63 pages in a single allocation. (check-in: 63597097ee user: dan tags: pager-blockalloc) | |
| 14:54 | When retrying a write() after an EINTR error on unix, be sure to also rerun the previous lseek(). Ticket [e59bdf6116036a] (check-in: 21452f3ae6 user: drh tags: trunk) | |
|
2011-08-18
| ||
| 17:47 | Ensure that the Tcl "db onecolumn" command returns an empty string if the SELECT statement returns zero rows. (check-in: 928bcaf0f0 user: dan tags: trunk) | |
|
2011-08-17
| ||
| 07:46 | Properly process x64 DLL exports, which do not contain a leading underscore, in the MSVC makefile. (check-in: d5936324d2 user: mistachkin tags: trunk) | |
| 02:19 | Add vdbesort.c to the MSVC makefile. (check-in: 8eaa2cd3f4 user: mistachkin tags: trunk) | |
| 00:40 | Use OP_Sort rather than OP_Rewind in order to sort the content of a new index on the CREATE INDEX statement. Add an ALWAYS() to the merge sort logic to document an unreachable branch. (check-in: f01766f423 user: drh tags: trunk) | |
|
2011-08-15
| ||
| 19:44 | Updated comments on the multiplexor extension. No changes to code. (check-in: 0f42ef697e user: drh tags: trunk) | |
| 15:37 | Fix an assert() in the merge-sort logic to account for I/O errors. (check-in: c1daa809a1 user: drh tags: trunk) | |
| 15:27 | New makefile target "sqlite3-debug.c" builds an amalgamation that include appropriate "#line" macros relating the code back to the original source files. (check-in: 26f2da24b0 user: drh tags: trunk) | |
| 14:41 | When opening a temporary file to use in a merge-sort, pass SQLITE_OPEN_TEMP_JOURNAL instead of SQLITE_OPEN_TEMP_DB. This is a better fit, as merge-sort files are written and read sequentially like journal files. (check-in: bd04756b66 user: dan tags: trunk) | |
|
2011-08-13
| ||
| 10:47 | Fix the header comment on the implementation of the file_control_sizehint_test TCL command in test1.c. (check-in: 309198085f user: drh tags: trunk) | |
|
2011-08-12
| ||
| 16:47 | Merge the experimental changes to use a merge-sort when creating an index into the trunk. (check-in: 346a453d1f user: dan tags: trunk) | |

2011-08-10
| ||
| 01:52 | Make the openDirectory routine in os_unix.c overrideable so that it can be turned into a harmless no-op for the chromium sandbox. (check-in: 6b236069e1 user: drh tags: trunk) | |
|
2011-08-09
| ||
| 18:14 | Add command-line utilities "offsets.c" and "extract.c" for use in low-level analyzsis of database files. (check-in: dfa22ed438 user: drh tags: trunk) | |
|
2011-08-08
| ||
| 23:48 | In os_unix.c, do not open the directory containing the database file when the database file is opened. Instead, wait until time to fsync() the directory. And do not report an error if the open fails, since some systems (Ex: AIX and a chromium sandbox) are unable to open and fsync directories. (check-in: 713b1b7dc1 user: drh tags: trunk) | |
| 23:18 | Allow the unlink() system call to be overridden in os_unix.c. (check-in: 8d1b5c3ac0 user: drh tags: trunk) | |
| 19:26 | Remove redundant parameter from vdbeSorterInitMerge() in vdbesort.c. (check-in: eec8c0df07 user: dan tags: experimental) | |

|
2011-08-07
| ||
| 01:31 | Remove relevant elements from the sqlite_stat2 table when doing a DROP INDEX or DROP TABLE. (check-in: 3c8f97ae52 user: drh tags: trunk) | |
|
2011-08-06
| ||
| 15:09 | Fix a problem with building large indexes introduced by the previous commit. (check-in: 038ec9ea92 user: dan tags: experimental) | |
| 12:01 | In temp files used for merge sorting, store the size of each packed-memory-array at the start of the array itself. This is to avoid having to store the offsets of all arrays in the (potentially very large) file in main-memory. (check-in: 8051c1767c user: dan tags: experimental) | |
|
2011-08-05
| ||
| 11:49 | Minor internal changes to vdbesort.c. Also, default to merging lists together 16 at a time. (check-in: 9ddc324a34 user: dan tags: experimental) | |
|
2011-08-04
| ||
| 18:43 | Fix a comment in vdbesort.c. (check-in: db8518cab8 user: dan tags: experimental) | |
| 12:14 | Change to using packed-memory-arrays instead of b-trees when performing an offline merge-sort for CREATE INDEX. This makes it easier to control the number of disc seeks required when merging. (check-in: a4770d079c user: dan tags: experimental) | |
