13:45
Save a few bytes in the parser by using "int" instead of "u8" or "u16" for all small integer types. (check-in: 5dcd212b user: drh tags: trunk)

Fix a comment typo in the lempar.c template that was missed by the prior check-in. (check-in: c4a7e93f user: drh tags: parser-enhancements)
19:33
Change the parser to use the standard "lempar.c" template over in the tool/ folder rather than the customized "lempar.c" found in src/. (check-in: 0a72991f user: drh tags: parser-enhancements)
15:06
Avoid recursion in the yy_find_shift_action() routine of the Lemon-generated parser, so that routine can be inlined, for a size reduction and performance increase. (check-in: 0557a179 user: drh tags: trunk)

Enhance TreeView to show WITH clauses. Add an assert to detect the infinite loop behavior when certain kinds of errors occur on a nested WITH clause. (check-in: 2040d88e user: drh tags: infinite-with-loop-bug)
01:33
Merge recent enhancements and bug fixes from trunk. (check-in: 78bc42e6 user: drh tags: sessions)
01:19
The OPFLAG_SEEKEQ optimization is only applicable to equality comparisons against an index, not against a rowid table. (check-in: 0f5b147d user: drh tags: trunk)
00:51
Fix a harmless sanitizer warning in the ieee754 extension. (check-in: dd9a26ec user: drh tags: trunk)
2015-11-06
20:22
Avoid an unnecessary key comparison when doing an indexed lookup against an equality constraint. (check-in: d741e1cc user: drh tags: trunk)
20:13
Work around a sign-extension bug in the optimizer on the HP C compiler that comes with HP/UX. (check-in: 46c36b15 user: drh tags: trunk)
20:04
Test changes: Omit numindex1.test from valgrind, since valgrind uses a none-standard floating-point processor which gives inconsistent answers. Run one releasetest.tcl module using LONGDOUBLE_TYPE=double. (check-in: d421efbf user: drh tags: trunk)
19:53
Enforce consistent comparison results between integer and floating point values. Fix for ticket [38a97a87a6e4e83]. (check-in: 849e686d user: drh tags: trunk)

17:01
Test cases for the ieee754 extension. (check-in: 840cbda8 user: drh tags: trunk)
14:59
A different approach to handling integer/float comparisons. This seems to work better on systems where "long double" and "double" are the same type, but still needs refinement and testing. (check-in: a3f7614b user: drh tags: int-float-precision)
12:50
Have fts5 load its configuration from the xConnect() method is invoked. This ensures that the very first query run uses the correct value of the 'rank' option. (check-in: 33e6606f user: dan tags: trunk)
04:14
More test cases for indexes on large numeric values. (check-in: c220741a user: drh tags: int-float-precision)
03:37
Some simple test cases from the mailing list. (check-in: 1d642b73 user: drh tags: int-float-precision)
01:04
Increase the precision of integer vs. floating-point comparisons. Candidate fix for ticket [38a97a87a6e4e8]. (check-in: cfcaa0ff user: drh tags: int-float-precision)
2015-11-05
22:30
Improvements and simplifications to the equality seek logic. Tests are adjusted so that they all pass now. (Closed-Leaf check-in: 997ce6c9 user: drh tags: seekeq-experiment)
21:49
Fix typo in help information for an FTS5 script. (check-in: 777ae800 user: mistachkin tags: trunk)
20:25
The top of an index equality loop normally starts with OP_SeekGE and OP_IdxGT. This check-in adds a flag to OP_SeekGE such that it fails immediately if the key is not equal, then jumps over the OP_IdxGT, saving a call to the key comparison functions. Consider this check-in a proof-of-concept. It needs improvement before going on trunk. Some tests fail, but only because they new use fewer key comparisons than expected (which is a good thing!). (check-in: 32e31b9b user: drh tags: seekeq-experiment)
18:09
Add the 'hashsize' configuration option to fts5, for configuring the amount of memory allocated to the in-memory hash table while writing. (check-in: 44548009 user: dan tags: trunk)
11:47
Remove a #pragma used to work around an issues with MSVC 2012 that has been overcome but subsequent changes. (check-in: 8303e4cf user: drh tags: trunk)
03:26
Remove #pragma that was used to work around an obsolete issue with MSVC 2012. (Closed-Leaf check-in: b9b22fae user: mistachkin tags: reoptimizeArm)
2015-11-04
22:31
Performance improvements in the getAndInitPage() routine of btree.c. (check-in: 2aa50f6f user: drh tags: trunk)
20:22
Rename the sqlite3PagerAcquire() function to sqlite3PagerGet(). The former macro called sqlite3PagerGet() has been removed. (check-in: 708253be user: drh tags: trunk)
