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.

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

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

09:54
Fix for [b1d3a2e531]. check-in: 3f3acee4 user: dan tags: trunk
2011-08-19
18:15

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

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

2011-08-16
17:06
Fix a few harmless compiler warnings. Add SQLITE_ENABLE_STAT3 to the standard compiler warning script. check-in: 3d68f9af user: drh tags: stat3-enhancement
02:07
Allow the sqlite3VdbeJumpHere() routine to accept a negative or zero address if a prior memory allocation error has occurred. The new sqlite_stat3 logic needs this. check-in: 9650d796 user: drh tags: stat3-enhancement
01:15
Add the analyze8.test test module for sqlite_stat3. check-in: 2c83ac89 user: drh tags: stat3-enhancement

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
12:58
Update some test cases to work with sqlite_stat3 instead of sqlite_stat2. check-in: 2504bcfb user: drh tags: stat3-enhancement

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: 6b236069 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: dfa22ed4 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: 713b1b7d user: drh tags: trunk
23:18
Allow the unlink() system call to be overridden in os_unix.c. check-in: 8d1b5c3a user: drh tags: trunk
19:26
Remove redundant parameter from vdbeSorterInitMerge() in vdbesort.c. check-in: eec8c0df user: dan tags: experimental
17:18
Add code to actually use the sqlite_stat2.cnt field in the query planner. This changes some plans resulting in a few failures in analyze5.test. Closed-Leaf check-in: d1248165 user: drh tags: query-planner-tweaks
16:44
Add fault-injection and other tests (and fixes) to improve coverage of vdbesort.c. check-in: 0e6defa6 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: 3c8f97ae user: drh tags: trunk
00:21
The ANALYZE command adds the sqlite_stat2.cnt column if it does not already exist. check-in: 794fde6f user: drh tags: query-planner-tweaks
2011-08-06
19:48
The sqlite_stat2.cnt field is parsed if it is present. But it is not yet used. A large comment added to analyze.c to explain the format of the ANALYZE system tables. check-in: 6d1e2372 user: drh tags: query-planner-tweaks
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
02:03
Merge together the fork in the query-planner-tweaks branch. check-in: 2daab6bd user: drh tags: query-planner-tweaks
