12 check-ins using file src/btree.c version 2a483a80
|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)|
|05:58||Fix harmless compiler warning. (check-in: 73311906 user: mistachkin tags: trunk)|
|15:49||Merge the latest trunk changes, including the multi-threaded sorter, into the sessions branch. (check-in: d4cce2c7 user: drh tags: sessions)|
|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.
