16:40

16:09
Fix a harmless comment typo. No code changes. check-in: ae687652 user: drh tags: trunk
14:43
Fix harmless compiler warnings. check-in: b0badb99 user: drh tags: trunk
12:58
Improved detection of database corruption in freeSpace(). check-in: 29bcb568 user: drh tags: trunk
10:49
Comment typo fix. No code changes. check-in: 17f185ad user: drh tags: trunk
2015-06-13
19:05
Added test cases based on Bruce Momjian's talk on SQL NULLs. Leaf check-in: 68c168b5 user: drh tags: is-distinct-from
11:48
Add the IS DISTINCT FROM and IS NOT DISTINCT FROM operators. check-in: 0be44782 user: drh tags: is-distinct-from
11:19
Omit mutex calls in pcache1 when the mutex is NULL, for a significant performance improvement. check-in: caf8f574 user: drh tags: trunk
11:10
Avoid unnecessary mutex usage in pcache1, for a significant speedup. Closed-Leaf check-in: dcf4fb8d user: drh tags: faster-pcache1-fetch
2015-06-12
13:49
Add a fast-path implementation of pcache1Fetch() for the common case of separate caches that do not use a mutex. check-in: 760700ed user: drh tags: faster-pcache1-fetch
13:04
Minor performance optimization in pcache1.c. check-in: 2e8ad2ea user: drh tags: trunk
12:54
Add the OP_ColumnsUsed opcode (when compiled with SQLITE_ENABLE_COLUMN_USED_MASK) as a hint to the b-tree layer as to which columns of a btree cursor will be used. check-in: 711a176c user: drh tags: trunk
2015-06-11
18:01
Merge recent trunk enhancements and fixes. check-in: c39cb0e2 user: drh tags: sessions
17:58
Merge trunk fixes. Leaf check-in: 1df8cbbe user: drh tags: view-optimization
14:19
Remove stray outputs from the test suite. check-in: afc6db9b user: drh tags: trunk
13:58
When generating code for partial indexes, be sure not to modify the index condition expression in the schema. check-in: e63d01c6 user: drh tags: trunk
2015-06-10
23:02
More test output refinements. Closed-Leaf check-in: e64a5681 user: mistachkin tags: testerOutput
22:51
Remove possibly stray output from various tests. check-in: f38e0be5 user: mistachkin tags: testerOutput
22:03
Fix minor typo in the quicktest MSVC makefile target. check-in: 75b65f9d user: mistachkin tags: trunk
20:00
Merge enhancements from trunk. check-in: 0e23a079 user: drh tags: view-optimization
18:53
"test" targets on all makefiles use --verbose=file --output=test-out.txt. Add the new "quicktest" target to all makefiles - designed to run in under three minutes. The --quick option on releasetest.tcl now uses quicktest. check-in: 6ddef2ad user: drh tags: trunk
17:20
Resolve FROM-clause subqueries after query planning instead of before. Greatly reduce the estimated cost of automatic indexes for VIEWs and ephemeral tables since performance problems there cannot be mitigated via a CREATE INDEX. check-in: a1eaf171 user: drh tags: view-optimization
14:27
Avoid passing constraints that are unusable due to LEFT or CROSS joins to virtual table xBestIndex() methods. check-in: 7b446771 user: dan tags: trunk
2015-06-09
15:58
Add the --output=$file and --verbose=(0|1|file) options to tester.tcl. check-in: f7b2c703 user: dan tags: trunk
10:58
Remove some repeated lines of source code. Probably introduced by careless cut'n'pasting. Closed-Leaf check-in: a34cd71c user: dan tags: vtab-left-join
2015-06-08
22:59
Code refactoring to try to shift FROM-clause subquery manifesting until after the query planner runs. Except this does not currently work because the query planner needs an estimated of the number of rows in the manifested table. Work in progress. check-in: cabf2187 user: drh tags: view-optimization
19:15
Add the valgrindfuzz target to unix makefile. check-in: e62aed01 user: drh tags: trunk
18:48
If a query contains "FROM t1 LEFT JOIN t2, t3, t4", ensure that tables t3 and t4 are not scanned before t2. The trunk already does this. check-in: 0d9edfab user: dan tags: vtab-left-join
18:05
Avoid passing constraints that are unusable due to LEFT or CROSS joins to virtual table xBestIndex() methods. check-in: 80ee56dd user: dan tags: vtab-left-join
17:42
Fix typo in comment. No changes to code. check-in: e49c2917 user: mistachkin tags: trunk
17:40
Split out some source code into new files: wherecode.c, whereexpr.c, and treeview.c. Other minor refactoring changes. check-in: 50f33681 user: drh tags: trunk
15:08
Factor out the TreeView parse tree printing module into a separate file. check-in: c32ce54c user: drh tags: view-optimization
14:23
Split more subfunctions of where.c out into a new whereexpr.c source file, for improved maintainability. check-in: 46ef95c1 user: drh tags: view-optimization
2015-06-06
20:12
Split out the bulk of the actual VDBE code generation logic from where.c into a new file, leaving behind the analysis logic. This makes the original where.c smaller and hopefully easier to edit. check-in: faa0e420 user: drh tags: view-optimization
18:30
Code simplifications in select.c and where.c. check-in: 4f20ac90 user: drh tags: view-optimization
00:18
Minor cleanup of the sqlite3Select() procedure. check-in: f4c90d06 user: drh tags: view-optimization
2015-06-05
22:33
Split FROM-clause subquery flattening and code generation into separate loops. check-in: be8e3fc7 user: drh tags: view-optimization
20:27
Provide one final Select tree dump prior to WHERE clause analysis when ".selecttrace 0x400" tracing bit is set with SELECTTRACE_ENABLED. Analysis and debug changes only - normal builds are unaffected. check-in: 283bf0b6 user: drh tags: trunk
15:59
Add a new opcode to the VDBE that gives the b-tree a hint about the set of columns in a table or index that are actually used by the query. Closed-Leaf check-in: f167bba4 user: drh tags: column-usage-hint
2015-06-04
12:08
Change the name of SrcList.a[].zIndex to the more descriptive SrcList.a[0].zIndexedBy. check-in: 6a9cf063 user: drh tags: trunk
