34 check-ins using file src/pager.c version 817f7f71

2011-09-02
18:03
Combine two malloc calls in vdbesort.c. (check-in: cf48ad83 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: 065b0c98 user: dan 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)
2011-08-26
20:55
Fix several harmless compiler warnings and a documentation bug. (check-in: 5454d0fe user: drh tags: trunk)
19:20
Merge the latest trunk changes into the sessions branch. (check-in: eb036d6f user: drh tags: sessions)
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)
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)
