2011-08-18
13:45
Fix the stat3 analysis loader to be compatible with sqlite3_db_status(). Also fix some OOM issues with the stat3 analysis loader. (Closed-Leaf check-in: eaf447ea user: drh tags: stat3-enhancement)
02:51
Fix a bug in the cleanup of stat tables on a DROP TABLE in autovacuum mode. (check-in: 3fe5d54f user: drh tags: stat3-enhancement)
01:10
Fix an error with OOM processing in the ANALYZE logic. (check-in: b26ec79c user: drh tags: stat3-enhancement)
2011-08-17
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)
2011-08-16
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)
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)
12:58
Update some test cases to work with sqlite_stat3 instead of sqlite_stat2. (check-in: 2504bcfb user: drh tags: stat3-enhancement)
12:02
Fix a couple of typos in comments in analyze.c. (check-in: ae31dc67 user: dan tags: stat3-enhancement)
2011-08-13
19:35
Further testing and bug fixing for sqlite_stat3. Added the Index.avgEq field to index statistics. Fixed several problems in the query planner associated with stat3. (check-in: 89b2f708 user: drh tags: stat3-enhancement)
15:25
Add the sqlite_stat3.nDLT field. Use an linear congruence PRNG to choose which samples to select from among those with the same nEq field. (check-in: 1dcd2428 user: drh tags: stat3-enhancement)
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)
00:58
The ANALYZE command picks for 15 samples for sqlite_stat3 with the largest nEq fields, plus 5 other evenly spaced samples. (check-in: 8225924e user: drh tags: stat3-enhancement)
2011-08-12
16:47
Merge the experimental changes to use a merge-sort when creating an index into the trunk. (check-in: 346a453d user: dan tags: trunk)
16:34
Update Makefile.in and configure to account for new source file vdbesort.c. (Closed-Leaf check-in: 69e4b41d user: dan tags: experimental)
16:30
Merge latest trunk changes into experimental branch. (check-in: 7e515055 user: dan tags: experimental)
01:51
Begin a branch that experimentally replaces sqlite_stat2 with a new table called sqlite_stat3 that will hopefully facilitate better query planning decisions. (check-in: 52e1d7e8 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)
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)
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)
02:03
Merge together the fork in the query-planner-tweaks branch. (check-in: 2daab6bd user: drh tags: query-planner-tweaks)
01:22
Fix a compiler warning when STAT2 is off. More test cases. Fix legacy tests to deal with the new STAT2 logic. (check-in: 7e914aa9 user: drh tags: query-planner-tweaks)
2011-08-05
22:31
Bug fixes to the sample-count logic for STAT2. A few test cases added. (check-in: e93c248c user: drh tags: query-planner-tweaks)
21:13
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)
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)
2011-08-02
23:45
Add explanatory comment to the win32lock-2.2 test case. (Closed-Leaf check-in: 4cb17881 user: mistachkin tags: winopen-retry-logic)
23:34
Correct subtle timing issues in the win32lock test cases and in the lock_win32_file Tcl command. Also, eliminate superfluous MSVC compiler warnings. (check-in: 7baf0294 user: mistachkin tags: winopen-retry-logic)
