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.

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)

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)

2011-08-16
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)

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

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)

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)

Remove relevant elements from the sqlite_stat2 table when doing a DROP INDEX or DROP TABLE. (check-in: 3c8f97ae user: drh tags: trunk)

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)

Add a column to the sqlite_stat2 table that contains the number of entries with exactly the same key as the sample. We do not yet do anything with this extra value. Some tests in analyze2.test are failing. (check-in: eb434228 user: drh tags: query-planner-tweaks)
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)
01:09
Allow the sqlite_stat2 table to contain a number of samples other than the default of 10. (check-in: b9d41c34 user: drh tags: query-planner-tweaks)

2011-08-03
22:06
Merge the winopen-retry-logic branch into trunk. The biggest change here is to test scripts, which should now use such as copy_file and delete_file from tester.tcl rather than the raw file commands of TCL. (check-in: b90c28be user: drh tags: trunk)
21:46
Merge the latest trunk changes into the sessions branch. (check-in: c5709036 user: drh tags: sessions)

Merge in the permutation changes from trunk. (check-in: b30a5e30 user: drh tags: winopen-retry-logic)
