| 19:41 | Merge latest changes from the trunk into the sessions branch. (check-in: c00e45ede7 user: dan tags: sessions) | |
| 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
| ||
| 19:08 | Allocate the correct size for the output buffer in fts3DoclistOrMerge(). Fix for [56be976859]. (check-in: 07788c0f7f user: dan 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

| 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

|
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
| ||

| 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) | |

| 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) | |
| 00:34 | Create a new pager type, PAGER_SORTER, for use in the external merge sort. Such pagers are always held in memory but do report when they are under memory pressure by calling pagerStress. (check-in: c71d73201d user: drh tags: trunk) | |
|
2011-08-25
| ||
| 20:18 | Reorder some of the branches in backup.c in order to make the code easier to test. (check-in: 2c443d47ec user: drh tags: trunk) | |
| 19:28 | Replace an assert() that a condition may not occur in backup.c with code to handle that condition, which can occur. (check-in: 472c74b345 user: dan tags: trunk) | |
| 18:54 | Fix harmless compiler warnings in test code. No changes to the core. (check-in: 16f83fec77 user: drh tags: trunk) | |

| 13:46 | Fix the SQLITE_DISABLE_DIRSYNC compile time option. (check-in: 6deb3ea1f0 user: dan tags: trunk) | |
| 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) | |
| 03:38 | Fix an file separator character issue with test_quota.c that was causing it to fail on windows. (check-in: ddb8d3e80d user: drh tags: trunk) | |
| 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) | |
| 01:58 | Cherrypick the [d4f6437f8d] change so that SQLITE_FCNTL_SIZE_HINT is always honored and never undone by memory pressure on windows. (check-in: 67ff8d27f6 user: drh tags: trunk) | |
| 01:42 | Add the sqlite3_quota_file() interface to test_quota.c. (check-in: 2b7fe8e5b7 user: drh tags: trunk) | |
| 01:16 | Make sure that SQLITE_FCNTL_SIZE_HINT on Windows does not shrink the file. (check-in: d4f6437f8d user: mistachkin tags: winNativeHeap) | |

|
2011-08-23
| ||
| 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) | |

| 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) | |

| 15:27 | 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

|
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) | |
