23 check-ins using file src/test1.c version 363a5089

2014-09-06
16:49
Fixes to os_unix.c to support database (and other) files larger than 2GiB. (check-in: e7fae33c user: dan tags: android-large-filles)
03:38
Do not record a page-size change if the attempt to change the page size failed due to an OOM error. (check-in: 4d4fb197 user: drh tags: trunk)
03:16
Add the sqlite3_memdebug_title_count global variable, used during debugging to count the number of invocations of test_memdebug_settitle. By examining this variable in the debugger after a segfault, one can then set a breakpoint on test_memdebug_settitle that will fire just before the problem. (check-in: 27e3ca3e user: drh tags: trunk)
02:00
Fix a couple of typos in comments. No changes to code. (check-in: a758465e user: mistachkin tags: trunk)
01:35
Query planner heuristic update: When doing a full table scan on a table that has an equality constraint on an unindexed column, do not allow the estimated number of output rows to be greater than half the total number of rows in the table. (check-in: 73954f93 user: drh tags: trunk)
2014-09-05
05:58
Fix harmless compiler warning. (check-in: 73311906 user: mistachkin tags: trunk)
2014-09-02
15:49
Merge the latest trunk changes, including the multi-threaded sorter, into the sessions branch. (check-in: d4cce2c7 user: drh tags: sessions)
2014-09-01
23:06
Update comments in the ANALYZE command that describe how the Stat4Accum objecct is passed around within the VDBE. No changes to functional code. (check-in: 9779c7a9 user: drh tags: trunk)
22:34
Avoid a confusing (though correct) argument to the sqlite3_result_blob() function in the implementation of ANALYZE. (check-in: 4cae93f8 user: drh tags: trunk)
19:29
For sqlite3_win32_is_nt(), assume WinRT is NT-based and revise #ifdef ordering to prefer the ANSI version of GetVersionEx, when available. (check-in: be0a0372 user: mistachkin tags: trunk)
18:21
Tweak the documentation for SQLITE_LIMIT_WORKER_THREADS. No changes to executable code. (check-in: 672e7387 user: drh tags: trunk)
17:36
Add support for using separate worker threads to speed large sorts. The SQLITE_MAX_WORKER_THREADS and SQLITE_DEFAULT_WORKER_THREADS compile-time options and the SQLITE_LIMIT_WORKER_THREADS argument to sqlite3_limit() and the "PRAGMA threads=N" pragma are added. (check-in: b1c0f0bc user: drh tags: trunk)
2014-08-29
19:06
Disable worker threads when SQLITE_THREADSAFE=0. Set the default compile-time maximum number of worker threads to 8 and honor the SQLITE_DEFAULT_WORKER_THREADS compile-time constant (which defaults to 0). (Closed-Leaf check-in: 33fa0410 user: drh tags: threads)
18:06
Fix the speedtest1.c test program to set the worker thread count using the threads pragma. (check-in: 2ab4b5ad user: drh tags: threads)
16:20
Add SQLITE_LIMIT_WORKER_THREADS for controlling the maximum number of worker threads. (check-in: 1b598c68 user: drh tags: threads)
14:40
Merge recent performance enhancements from trunk onto the threads branch. (check-in: 35c44a3c user: drh tags: threads)
2014-08-25
23:44
Remove the SQLITE_CONFIG_WORKER_THREADS configuration parameter. The number of worker threads in the sorter is now determined only by the PRAGMA threads=N setting. (check-in: e3305d4b user: drh tags: threads)
22:43
Merge the CAST operator enhancements from trunk. (check-in: 6c8f86e4 user: drh tags: threads)
15:13
Query or change the maximum number of worker threads allowed on each database connection separately using the "PRAGMA threads" command. (check-in: 29c5e8a7 user: drh tags: threads)
13:27
Merge the recent performance enhancements implemented on trunk into the threads branch. (check-in: dfdc900f user: drh tags: threads)
2014-08-15
15:46
Merge the 3.8.6 release into the threads branch. (check-in: 05807c41 user: drh tags: threads)
2014-08-14
14:02
Merge the pre-3.8.6 changes into the threads branch. (check-in: a608fd1d user: drh tags: threads)
2014-08-06
02:03
Merge all recent changes from trunk. (check-in: a353a851 user: drh tags: threads)
