| 14:20 | Refactor the sqlite3VdbeRecordUnpack() interface to better accommodate the vdbesort.c module. (check-in: f115b230 user: dan tags: trunk) | |
|
2011-09-04
| ||
| 01:27 | Fix a compiler warning about an unused parameter in the merge-sort code. (check-in: 6b657ae7 user: drh tags: trunk) | |
| 01:11 | Improve the testability of the merge-sort logic. (check-in: b5179baf 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: 4c43e8b2 user: drh tags: trunk) | |
| 16:42 | Simplification and performance tweaks in vdbeSorterMerge(). (Closed-Leaf check-in: 99e34bdc user: drh tags: merge-sort) | |
| 14:36 | Reduce the number of VdbeRecordUnpack() calls made in vdbesort.c. (check-in: 666c2c3c 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: 68e26c44 user: drh tags: merge-sort) | |
|
2011-09-02
| ||
| 21:42 | Remove some dead code. Fix a faulty assert(). Improve some variable names. (check-in: a9a64592 user: drh tags: merge-sort) | |

| 15:08 | Remove unused local variable. (check-in: 61bda876 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: 71075673 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: 7769fb98 user: dan tags: merge-sort) | |
|
2011-09-01
| ||
| 16:01 | Use OP_SorterOpen instead of OP_OpenEphemeral to implement GROUP BY. (check-in: ebf819aa user: drh tags: merge-sort) | |
| 15:32 | Experimental code-generator changes to utilize new opcodes for sorting. (check-in: bab2e560 user: drh tags: merge-sort) | |
|
2011-08-31
| ||
| 23:57 | Avoid using uninitialized variables after failures in the merge sort code. (check-in: 2869ed28 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: 70b5b309 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: 1b124af4 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: 64898485 user: drh tags: trunk) | |
| 18:35 | Always include the unixShm.id field, even when not debugging. (check-in: 07803476 user: drh tags: trunk) | |
| 18:04 | Only create the sqlite3OSTrace global variable if compiling with SQLITE_TEST. (check-in: 9e6a4c14 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: df550066 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: d0b347b4 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: 20ddfb47 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: f1bd5bba 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: 88b763e8 user: mistachkin tags: trunk) | |
| 00:58 | Fix a total unimportant file descriptor leak in lemon. This is to silence warning messages. (check-in: e95cf2c5 user: drh tags: trunk) | |
| 00:53 | Fix a buffer overrun in test logic. No impact on the core SQLite. (check-in: 49cd60e3 user: drh tags: trunk) | |
|
2011-08-29
| ||
| 18:24 | Fix a broken assert() statement in select.c. (check-in: ad78ef2b user: dan tags: trunk) | |
| 11:56 | Back out [05c9832e5f6eb] since it was causing a performance regression with no obvious benefit. (check-in: 639cc85a user: drh tags: trunk) | |
| 03:08 | Merge performance enhancements into trunk. (check-in: 5a00d24b 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: ff71d20a user: drh tags: experimental) | |
| 02:16 | Small performance improvement to OP_Column. (check-in: b6b73a74 user: drh tags: experimental) | |
|
2011-08-28
| ||
| 02:15 | About a 3% improvement in the performance of OP_Column. (check-in: edff9d4a 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: 087dc960 user: drh tags: experimental) | |
|
2011-08-27
| ||
| 18:48 | Experimental changes to improve the performance of OP_Next. (check-in: 1a249845 user: dan tags: experimental) | |

| 13:16 | Merge the stat3-enhancement branch with trunk, but keep the resulting merge in a separate branch for now. (check-in: 63f2c785 user: drh tags: stat3-trunk) | |
| 11:25 | Update compiler error message regarding the choice of memory allocator defines. (check-in: 1dada515 user: mistachkin tags: trunk) | |
| 11:18 | Merge Win32 native heap support into trunk. (check-in: 5238a749 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: 5ed7633d user: mistachkin tags: winNativeHeap) | |
| 01:45 | Disable checking the winMemData structure signature when compiled with NDEBUG. (check-in: 50edc2f9 user: mistachkin tags: winNativeHeap) | |
| 01:32 | Allow the Win32 native heap flags to be overridden at compile-time. (check-in: 1c2ecec8 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: c71d7320 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: 2c443d47 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: 472c74b3 user: dan tags: trunk) | |
| 18:54 | Fix harmless compiler warnings in test code. No changes to the core. (check-in: 16f83fec user: drh tags: trunk) | |
| 18:01 | Disable external merge source when SQLITE_TEMP_STORE==3. Add documentation to the OP_OpenSorter opcode. (check-in: 5a690486 user: drh tags: trunk) | |
| 13:46 | Fix the SQLITE_DISABLE_DIRSYNC compile time option. (check-in: 6deb3ea1 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: 40185923 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: ddb8d3e8 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: 4257e9b7 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: 67ff8d27 user: drh tags: trunk) | |
| 01:42 | Add the sqlite3_quota_file() interface to test_quota.c. (check-in: 2b7fe8e5 user: drh tags: trunk) | |
| 01:16 | Make sure that SQLITE_FCNTL_SIZE_HINT on Windows does not shrink the file. (check-in: d4f6437f user: mistachkin tags: winNativeHeap) | |
| 00:14 | Add the SQLITE_EXTRA_INIT macro. (check-in: a3220f36 user: drh tags: trunk) | |
|
2011-08-24

| 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: 04111ce9 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: d5d835fe 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: 880b5115 user: drh tags: trunk) | |
| 19:46 | Change the way the "crash" VFS (test6.c) handles SQLITE_FCNTL_SIZE_HINT. (check-in: 40dd8a60 user: dan tags: trunk) | |
| 18:06 | Merge latest trunk changes into the apple-osx branch. (check-in: c5f7977b user: dan tags: apple-osx) | |
| 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: fac8bc8f user: dan tags: trunk) | |
| 13:27 | Ifdef out routines in pcache1.c that are used only when SQLITE_PAGECACHE_BLOCKALLOC is defined. (check-in: 0da292da user: drh tags: trunk) | |
| 12:50 | Merge the PAGECACHE_BLOCKALLOC changes into trunk. (check-in: 768c1846 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: 35e6ac18 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: ca47da2a user: dan tags: pager-blockalloc) | |
| 00:01 | Remove a branch that is always true. (check-in: a6568192 user: drh tags: trunk) | |
|
2011-08-22
| ||
| 20:33 | Remove an unreachable branch in the FK code. (check-in: 6c227cc8 user: drh tags: trunk) | |
| 14:55 | Modify test cases so that veryquick.test passes with PAGECACHE_BLOCKALLOC defined. (check-in: c6100070 user: dan tags: pager-blockalloc) | |
| 09:54 | Fix for [b1d3a2e531]. (check-in: 3f3acee4 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: 63597097 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: 21452f3a 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: 928bcaf0 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: d5936324 user: mistachkin tags: trunk) | |
| 02:19 | Add vdbesort.c to the MSVC makefile. (check-in: 8eaa2cd3 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: f01766f4 user: drh tags: trunk) | |
|
2011-08-15
| ||
| 19:44 | Updated comments on the multiplexor extension. No changes to code. (check-in: 0f42ef69 user: drh tags: trunk) | |
| 15:37 | Fix an assert() in the merge-sort logic to account for I/O errors. (check-in: c1daa809 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: 26f2da24 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: bd04756b 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: 30919808 user: drh tags: trunk) | |
|
2011-08-12

|
2011-08-06
| ||
| 15:09 | Fix a problem with building large indexes introduced by the previous commit. (check-in: 038ec9ea 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: 8051c176 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: 9ddc324a user: dan tags: experimental) | |
|
2011-08-04
| ||
| 18:43 | Fix a comment in vdbesort.c. (check-in: db8518ca 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: a4770d07 user: dan tags: experimental) | |
|
2011-08-02
| ||
| 10:56 | Minor fixes to vdbesort.c code in preparation for a major rework. (check-in: 7f339c0e user: dan tags: experimental) | |
