21:35
Testability improvement. (Closed-Leaf check-in: eed6a331 user: drh tags: btree-opt2)
18:47
Improve test coverage of fts5. (check-in: df5ccea8 user: dan tags: fts5)
18:24
Multiple overflow cells are always adjacent and sequential. Exploit this invariant for a small size reduction and performance increase and add assert()s to prove the invariant. (check-in: f77f2f48 user: drh tags: btree-opt2)
17:09
Faster loading of cell pointers into the b.apCell array in balance_nonroot. (check-in: fda89b05 user: drh tags: btree-opt2)
16:00
Avoid unnecessary cachedCellSize() calls in the cell partition adjustment phase of balance_nonroot(). (check-in: 6319ee12 user: drh tags: btree-opt2)
15:36
Change pageInsertArray() and pageFreeArray() so that they use the CellArray object and compute cell sizes as needed, resulting in smaller and faster code. (check-in: f7f41818 user: drh tags: btree-opt2)
15:06
Merge latest trunk changes with this branch. Add tests for columnsize=0. (check-in: ef44c71a user: dan tags: fts5)

12:19
Test that the left and right sides of a compound SELECT operator have the same number of expressions in the expanded expression list before beginning to generate code. (check-in: 4df852ce user: dan tags: trunk)
02:37
Avoid computing cell sizes in balance_nonroot() until they are really needed. This gives an overall 1.7% performance gain for about 1000 extra bytes of code space. (check-in: 43844537 user: drh tags: btree-opt2)
2015-06-22
20:02

2015-06-20
18:13
Split out all four cases of cellSizePtr() into different methods, each optimized for the specific page type. This gives a 0.36% performance increase at a cost of about 300 bytes of code. (Leaf check-in: 522502ec user: drh tags: btree-opt)
14:11
Update the fuzztest data using the latest test vectors discovered by AFL. (check-in: b97f9cf7 user: drh tags: trunk)

Performance improvements in btreeParseCell() by inlining the varint decoder. (check-in: faab0ed9 user: drh tags: btree-opt)
17:19
Add the MemPage.xParseCell method and provide various implementations (variations on the former btreeParseCellPtr()) depending on the page type. (check-in: 41d03d88 user: drh tags: trunk)
15:07
Make cellSizePtr() a method on the MemPage object, with alternative implementations depending on the page type. This results is a small performance improvement and size reduction. (check-in: 02f7e9d7 user: drh tags: trunk)
2015-06-18
15:26
Further #ifdef changes in speedtest1.c in order to support SQLite back to version 3.3.9 and perhaps even earlier. (check-in: 9246eca5 user: drh tags: trunk)

01:31
Optimizations to two VDBE accessory routines for a 0.2% performance increase. (check-in: 66d033b9 user: drh 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)

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

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)
19:23
Fix a comment in fts5.h. (check-in: e964b587 user: dan tags: fts5)
18:30
Code simplifications in select.c and where.c. (check-in: 4f20ac90 user: drh tags: view-optimization)
16:28

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)
19:05
Make use of range constraints on the rowid field of an fts5 table in full-text queries. (check-in: 32cbc0ed user: dan tags: fts5)
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)
2015-06-03
11:23
Fix an fts5 problem in extracting columns from position lists containing large varints. (check-in: 4ea015ab user: dan tags: fts5)
2015-06-02

Rename SQLITE_AFF_NONE to SQLITE_AFF_BLOB to avoid confusion with "no affinity". (check-in: 29ad9e91 user: drh tags: trunk)
16:09

15:32
Rename SQLITE_AFF_NONE to SQLITE_AFF_BLOB. (Closed-Leaf check-in: bce3f041 user: drh tags: blob-affinity-rename)

17:51
Move two unreachable conditionals inside of NEVER() or assert(). (check-in: db4e9728 user: drh tags: trunk)

13:55
An attempt to allow automatic index creation on subqueries accessed via co-routine. (check-in: 521345ad user: drh tags: coroutine-autoindex)
01:35
Using "SELECT ALL" instead of just "SELECT" on a query that uses a single unflattenable subquery or view in its FROM clause will force the subquery to be manifested into a temporary table rather than run incrementally using a co-routine. This is a stop-gap means of controlling the decision to manifest while we try to work out a better to make that decision automatically. (check-in: a29e117d user: drh tags: trunk)
2015-05-28
15:14

15:10
Disallow the use of "rowid" in CTEs - it has never worked correctly and it makes no sense, so we might as well make it an explicit error. Also: add the PRAGMA cell_size_check=ON command. (check-in: 19e2cebc user: drh tags: trunk)
14:21
A different approach to preventing buffer overreads when comparing a vector of values with a corrupt index record that spans at least one overflow page. (Closed-Leaf check-in: 7e9e1b61 user: dan tags: avoid-buffer-overread)
13:06

20:07
Avoid branching on an uninitalized variable when comparing SQL values with the undefined serial types 10 and 11 (which only appear in corrupt databases). (check-in: b4a45d3b user: dan tags: trunk)
19:08
