| 17:58 | Merge trunk fixes. (Leaf check-in: 1df8cbbea6 user: drh tags: view-optimization) | |
| 17:26 | Add the sqlite3changegroup_xxx() APIs to the sessions module. For combining multiple changesets or patchsets. (check-in: 0c1a901cd6 user: dan tags: sessions) | |
| 14:19 | Remove stray outputs from the test suite. (check-in: afc6db9b10 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: e63d01c69c user: drh tags: trunk) | |

| 23:02 | More test output refinements. (Closed-Leaf check-in: e64a568179 user: mistachkin tags: testerOutput) | |
| 22:51 | Remove possibly stray output from various tests. (check-in: f38e0be56f user: mistachkin tags: testerOutput) | |
| 22:03 | Fix minor typo in the quicktest MSVC makefile target. (check-in: 75b65f9d49 user: mistachkin tags: trunk) | |
| 20:00 | Merge enhancements from trunk. (check-in: 0e23a079bd 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: 6ddef2ad35 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: a1eaf1718e 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: 7b446771ca user: dan tags: trunk) | |
| 10:45 | Fix the fts5 xRename() method. (check-in: 0f7fd51325 user: dan tags: fts5) | |
|
2015-06-09
| ||
| 20:58 | Add the "columnsize=" option to fts5, similar to fts4's "matchinfo=fts3". (check-in: aa12f9d9b7 user: dan tags: fts5) | |
| 15:58 | Add the --output=$file and --verbose=(0|1|file) options to tester.tcl. (check-in: f7b2c70362 user: dan tags: trunk) | |
| 10:58 | Remove some repeated lines of source code. Probably introduced by careless cut'n'pasting. (Closed-Leaf check-in: a34cd71c8a 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: cabf218716 user: drh tags: view-optimization) | |
| 19:15 | Add the valgrindfuzz target to unix makefile. (check-in: e62aed01f1 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: 0d9edfab9f 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: 80ee56dda7 user: dan tags: vtab-left-join) | |
| 17:42 | Fix typo in comment. No changes to code. (check-in: e49c291735 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: 50f336818c user: drh tags: trunk) | |
| 15:08 | Factor out the TreeView parse tree printing module into a separate file. (check-in: c32ce54ca4 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: 46ef95c108 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: faa0e420e9 user: drh tags: view-optimization) | |
| 19:23 | Fix a comment in fts5.h. (check-in: e964b58774 user: dan tags: fts5) | |
| 18:30 | Code simplifications in select.c and where.c. (check-in: 4f20ac90bc user: drh tags: view-optimization) | |
| 16:28 | Fix handling of fts5 rowid constraints in the absence of a MATCH clause. Add tests to cover recently added branches. (check-in: 3a9cb64813 user: dan tags: fts5) | |
| 00:18 | Minor cleanup of the sqlite3Select() procedure. (check-in: f4c90d06bb user: drh tags: view-optimization) | |
|
2015-06-05
| ||
| 22:33 | Split FROM-clause subquery flattening and code generation into separate loops. (check-in: be8e3fc70e 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: 283bf0b64d 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: 32cbc0ed36 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: f167bba446 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: 6a9cf06337 user: drh tags: trunk) | |
|
2015-06-03
| ||
| 11:23 | Fix an fts5 problem in extracting columns from position lists containing large varints. (check-in: 4ea015ab98 user: dan tags: fts5) | |
|
2015-06-02
| ||
| 19:38 | Change the fts5 multi-column syntax to use parenthesis instead of square brackets. (check-in: ab85a6fc4f user: dan tags: fts5) | |
| 19:36 | Always check for cell overflow before returning a slot from the pageFindSlot routine in btree.c. (check-in: 9f035c45a4 user: drh tags: trunk) | |
| 18:09 | For FROM-clause subqueries that cannot be flattened, try to push relevant WHERE clause terms of the outer query down into the subquery in order to help the subquery run faster and/or use less memory. Call this the "WHERE-clause push-down optimization". Do not confuse this with the completely different MySQL push-down optimization. (check-in: 6df18e949d user: drh tags: trunk) | |
| 18:07 | Merge latest trunk changes with this branch. (check-in: c9ffda4abb user: dan tags: fts5) | |
| 17:57 | Reimplement [ec69e09a] so that each call to the xNext() method does not involve two iterations of the match expression tree (only one). (check-in: 80fe305b3e user: dan tags: fts5) | |
| 17:25 | Add test cases for type affinity rules. (check-in: 9678646d9a user: drh tags: trunk) | |
| 16:19 | Rename SQLITE_AFF_NONE to SQLITE_AFF_BLOB to avoid confusion with "no affinity". (check-in: 29ad9e9173 user: drh tags: trunk) | |
| 16:09 | Add the built-in affinity() SQL function. This turns out to be not as useful as originally envisioned, so abandon it on a branch. (Leaf check-in: 80889306bf user: drh tags: affinity-func) | |
| 15:32 | Rename SQLITE_AFF_NONE to SQLITE_AFF_BLOB. (Closed-Leaf check-in: bce3f04186 user: drh tags: blob-affinity-rename) | |
| 14:02 | Fix a faulty assert() in btree.c. Update the database fuzz test file with new test cases. (check-in: 4e621af134 user: drh tags: trunk) | |
| 09:20 | Add the "finish_test" command to the end of new test script sessionE.test. (check-in: fb39140707 user: dan tags: sessions) | |
| 09:19 | Modify the sessions module to ignore all operations on tables with no primary keys as documented. (check-in: bdaf9575cd user: dan tags: sessions) | |

| 20:28 | For FROM-clause subqueries that cannot be flattened, try to push WHERE clause terms of the outer query down into the subquery in order to help the subquery run faster and/or use less memory. (Closed-Leaf check-in: 297fae7551 user: drh tags: subquery-opt) | |
| 19:17 | Improve performance of the fts5 AND operator. (check-in: b43e9a5b7a user: dan tags: fts5) | |
| 18:13 | Corrections to comments in expr.c. No code changes. (check-in: f925389eaf user: drh tags: trunk) | |
| 17:32 | Break out the query flattener into a separate source-code file. (Closed-Leaf check-in: e3fa8b936b user: drh tags: flattener-in-new-file) | |
