50 check-ins using file src/build.c version d65be622

2016-05-20
14:54
Optimizations to link list merge sort code in vdbesort.c, pcache.c, and rowset.c. Resulting binaries are 10 bytes smaller and use 0.03% fewer CPU cycles. check-in: 9033afbb user: drh tags: trunk
14:11
For queries with both ORDER BY and LIMIT, if the rows of the inner loop are emitted in ORDER BY order and the LIMIT has been reached, then optimize by exiting the inner loop and continuing with the next cycle of the first outer loop. check-in: 559733b0 user: drh tags: trunk
13:44
Set the NULLEQ flag on the sequence counter comparison in the ORDER BY LIMIT optimization, to avoid coverage complaints about not testing the NULL case. Closed-Leaf check-in: ed1b30dc user: drh tags: orderby-limit
12:22
Autoconf configure.ac adjustment to try to get it to look for both editline and readline automatically. check-in: 645bd696 user: drh tags: trunk
00:21
A few simple test cases for the ORDER BY LIMIT optimization. check-in: 08849eab user: drh tags: orderby-limit
2016-05-19
22:40
Appears to work now. Needs test cases, more comments, and code optimization. check-in: 990fe50c user: drh tags: orderby-limit
22:13
In a query with both ORDER BY and LIMIT, if the inner loop satisfies the ORDER BY then try to cut short each invocation of the inner loop once the LIMIT has been satisfied. This check-in is a partial implementation only. check-in: 852d1eda user: drh tags: orderby-limit
19:31
Fixup comments on wctrlFlags value definitions. check-in: 58b516e8 user: drh tags: trunk

2016-05-17
21:17
Enhance the scrub utility program so that it does a FULL checkpoint prior to starting the backup, to ensure that the database file content matches what needs to be backed up without having to look at the WAL file. Closed-Leaf check-in: ab1c5ce5 user: drh tags: scrub-backup
17:11
Merge the latest changes from trunk. check-in: 5021dfe1 user: drh tags: scrub-backup
