[33fa041049] Leaf: 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). (user: drh, tags: threads)
18:06
[2ab4b5adc6] Fix the speedtest1.c test program to set the worker thread count using the threads pragma. (user: drh, tags: threads)
16:20
[1b598c68f3] Add SQLITE_LIMIT_WORKER_THREADS for controlling the maximum number of worker threads. (user: drh, tags: threads)
14:40
[35c44a3c73] Merge recent performance enhancements from trunk onto the threads branch. (user: drh, tags: threads)
14:20
[2a74129a21] Note a fault after all, rather a testing mistake. Move this change back to trunk. Was: Avoid an unnecessary OP_Move operation for expression subqueries. (user: drh, tags: trunk)
12:29
[462f42af52] Closed-Leaf: Contains a fault. Was: Avoid an unnecessary OP_Move operation for expression subqueries. (user: drh, tags: mistake)
11:24
[8c57bcc327] Closed-Leaf: Add the sqlite3VdbeChangeDest() routine that can be used to eliminate OP_Move opcodes. (user: drh, tags: experimental)
2014-08-28
19:38
[fdd478bb11] Improved WHERETRACE messages for the estimated output row reductions from range scans. (user: drh, tags: trunk)
17:30
[a9daf3ac44] Fix a problem causing an inaccurate stat4-based estimate for the number of rows visited by a range scan. (user: drh, tags: trunk)
17:20
[6ba609522e] Closed-Leaf: Add a testcase() macro to help verfity the row estimation logic. (user: drh, tags: stat4-experimental)
16:01
[052d89b554] Fix a problem causing an inaccurate stat4-based estimate for the number of rows visited by a range scan. (user: dan, tags: stat4-experimental)
13:42
[c931ca2b77] Fix a formatting error ("%d" needed in place of "%g") on a WHERETRACE macro inside of the query planner. This fix applies to debugging logic only. (user: drh, tags: trunk)
2014-08-27
23:18
[bdb6e4978d] Refactor the sqlite3PcacheFetch() routine into three separate routines, which are significantly faster overall and about 100 bytes smaller in size as well. (user: drh, tags: trunk)
17:53
[029a6dc744] Add a VDBE synopsis comment for clarification. (user: mistachkin, tags: trunk)
17:48
[d8b1c43361] Add a missing ticket number to a comment in index7.test. (user: dan, tags: trunk)
17:37
[fcebca166f] When determining whether or not a partial index is usable, do not assume that the cursor number assigned to each table in the query is the same as its index in the FROM clause. Fix for ticket [98d973b8f5]. (user: dan, tags: trunk)
14:14
[6c1ee3e388] In the sqlite3_context object, keep a pointer to the result value rather than storing the result value in the sqlite3_context object and using memcpy() to move the value back into its register after the function returns. This runs faster and saves over 500 bytes of code space. (user: drh, tags: trunk)
