20 check-ins using file src/vdbe.c version fee8286f

2014-10-11
17:22
Simplification to the insertCell() routine in btree.c, resulting in a performance boost and a very small size decrease. It turns out that the extra work involved in sometimes avoiding an memcpy() of the first four bytes of a record takes more time than just unconditionally copying those four bytes. (check-in: 66de1558 user: drh tags: trunk)
10:52
Require the SQLITE_ENABLE_RTREE compile-time option in speedtest1.c in order to enable the R-Tree tests. (check-in: 5d29a033 user: drh tags: trunk)
02:12
Make sure that a GROUP BY that also implements an ORDER BY scans the table in the correct order. Fix for ticket [ba7cbfaedc7e6]. (check-in: 7a32fdfd user: drh tags: trunk)
01:22
Remove an unnecessary conditional from the EXPLAIN QUERY PLAN logic. (check-in: c5dc83eb user: drh tags: trunk)
2014-10-10
20:52
Account for the ASC/DESC properties of ORDER BY expressions when using the same index for GROUP BY and ORDER BY. Candidate fix for [ba7cbfaedc]. (Closed-Leaf check-in: 2a957396 user: dan tags: experimental)
19:15
Restrict the scope of the explainIndexRange() function in where.c. (check-in: c3012452 user: drh tags: trunk)
19:10
Fix a failing test case in index5.test. Also tweak the way cache memory is divided between read-only and dirty pages when using SQLITE_CONFIG_PAGECACHE to reduce IO in some cases. (check-in: 8541dfb3 user: dan tags: trunk)
18:09
Changes to enable compiling using VC6. (check-in: 9ee5686a user: drh tags: trunk)
17:47
When using the -config option to releasetest.tcl, default the testing type to "fulltest" if it is not specified on the command line. (check-in: cf291cbe user: drh tags: trunk)
17:44
Provide the new "-config CONFIG" option to the test/releasetest.tcl script, which allows one to run a single test configuration selected by name. (check-in: d479e32b user: drh tags: trunk)
17:20
Add the estimated number of output rows to the EXPLAIN QUERY PLAN output if compiled with SQLITE_EXPLAIN_ESTIMATED_ROWS. This feature is off by default for the time being. (check-in: daa8314f user: drh tags: trunk)
15:47
Simplify the code used to generate the text for EXPLAIN QUERY PLAN. (check-in: beea1efc user: drh tags: trunk)
15:01
Fix a potential problem in the whereRangeScanEst() routine when STAT4 is active. The problem was introduced by recent enhancements. (check-in: 68e1b4de user: drh tags: trunk)
13:08
Cause the command-line shell to return non-zero if the final SQL statement is incomplete. (check-in: 177fff3b user: drh tags: trunk)
2014-10-09
15:08
Allow FTS tokenizers to choose whether or not to consider the "*" character part of tokens or not. This restores the pre-[e21bf7a2ad] behaviour. Also fix a problem causing FTS to interpret tokens beginning with "*" characters as EOF. (check-in: 49dfee7c user: dan tags: trunk)
14:10
Add a test case for the memory leak fixed by the previous check-in. (check-in: bae36d54 user: drh tags: trunk)
14:00
Fix a memory leak associated with the FTS4 matchinfo() function. (check-in: fb8da824 user: drh tags: trunk)
2014-10-08
19:33
Remove an always-true branch in whereRangeScanEst(). Replace it with an assert(). (check-in: 42e48fd3 user: drh tags: trunk)
15:53
Fix up test cases to account for the new SQLITE_LIMIT_WORKER_THREADS limit. (check-in: 6483d426 user: drh tags: trunk)
14:28
Set the connection-specific lastRowid value before calling any SQL function. (check-in: dff0f642 user: drh tags: trunk)
