25 check-ins using file src/pager.c version 3910579b

2016-05-20
15:53
Performance optimization and size reduction on the freeP4() routine. check-in: 4dc56e86 user: drh tags: trunk
15:24
Increase the version number to 3.14.0 since we are already making significant code changes. check-in: 1a0d0576 user: drh tags: trunk
15:15
Use sqlite3VdbeAddOp0() to code OP_Expire, to save a few bytes. check-in: 3d55d24d user: drh tags: trunk
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
18:56
Clean up the WHERE_* macros used for the wctrlFlags parameter on the sqlite3WhereBegin() interface, freeing up some bits to be used for other things. check-in: d0130584 user: drh tags: trunk
17:51
Optimization marks in vdbe.c. No logic changes. check-in: cf273741 user: drh tags: trunk
16:58
Performance improvement in the OP_Column opcode. check-in: 4737cadc user: drh tags: trunk
16:21
Add test cases to test some fts3/4 edge case behaviour surrounding the '*' character. check-in: 1f577e1f user: dan tags: trunk
11:12
Small size reduction and performance improvement in the OP_Column opcode. check-in: 0d773061 user: drh tags: trunk
2016-05-18
21:03
Add the "scrub" utility program that simultaneously backs-up a live database and erases all deleted content. check-in: c981ab2a user: drh tags: trunk
21:01
Omit the unnecessary WHERE_REOPEN_IDX flag in the WHERE interface. check-in: 915416d1 user: drh tags: trunk
10:57
Version 3.13.0 check-in: fc49f556 user: drh tags: trunk, release, version-3.13.0
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
2016-05-16
14:35
Do not run snapshot_fault.test as part of the inmemory_journal permutation. check-in: 995c084b user: dan tags: trunk
11:55
Disable shell.exe test cases for UTF8 filenames as they do not work on MinGW. check-in: 386bcbba user: drh tags: trunk
2016-05-13
17:22
Improvements to a comment in the pcache.c file. No changes to code. check-in: b369980f user: drh tags: trunk
15:22
Remove the unused PGHDR_NEED_READ flag. Add invariant checking (during SQLITE_DEBUG builds only) for the PgHdr object. check-in: 771c5411 user: drh tags: trunk
