| 20:56 | Merge trunk fixes for "x IN (?)" handling. (check-in: eca35871c3 user: drh tags: orderby-planning) | |
| 19:04 | Remove a testcase() that is now always true due to the "x IN (?)" optimization. Add an ALWAYS() around a conditional in the parser that cannot be false. (check-in: d5a1530bdc user: drh tags: trunk) | |
| 18:45 | Fix the EXPLAIN indenter in the command-line shell to correctly handle NextIfOpen and PrevIfOpen opcodes. (check-in: 01944c53f5 user: drh tags: trunk) | |
| 17:03 | The "x IN (?)" optimization in check-ins [2ff3b25f40] and [e68b427afb] is incorrect, as demonstrated by the in4-5.1 test case in this check-in. The "COLLATE binary" that was being added to the RHS of IN was overriding the implicit collating sequence of the LHS. This change defines the EP_Generic expression node property that blocks all affinity or collating sequence information in the expression subtree and adds that property to the expression taken from RHS of the IN operator. (check-in: 2ea4a9f75f user: drh tags: trunk) | |
| 15:14 | Fix harmless compiler warnings. (check-in: b1435f26b0 user: drh tags: trunk) | |
| 14:56 | Previous check-in is not quite correct. "x IN (?)" is not exactly the same as "x==?" do to collation and affinity issues. The correct converstion should be to "x==(+? COLLATE binary)". The current check-in fixes this problem and provides test cases. Ticket [e39d032577df69] (check-in: 2ff3b25f40 user: drh tags: trunk) | |
| 13:26 | Convert expressions of the form "X IN (?)" with exactly one value on the RHS of the IN into equality tests: "X=?". Add test cases to verify that statements work correctly on this corner case. Fix for ticket [e39d032577df6942]. (check-in: e68b427afb user: drh tags: trunk) | |
| 12:17 | Fix an unnecessarily obtuse use of a bitmask flag. (check-in: ca31408131 user: drh tags: trunk) | |

| 23:42 | Merge the vdbesort.c optimization from trunk. (check-in: e4bfffb988 user: drh tags: orderby-planning) | |
| 23:24 | Fix query planner weights associated with choosing block-sorting. Fix block sorting of tables with collating functions. Fix various test cases. All "veryquick" tests are now passing, though more tests need to be added. (check-in: 01afbf97c0 user: drh tags: orderby-planning) | |
| 20:01 | Avoid some unnecessary calls to sqlite3VdbeRecordUnpack() that were being made when merging data from two or more temp files together in vdbesort.c (check-in: 707ea170b3 user: dan tags: trunk) | |
| 17:41 | Make it possible for block-sort to use the OP_SorterOpen sorter in addition to a generic OP_OpenEphemeral. (check-in: 7ce2daafd3 user: drh tags: orderby-planning) | |
| 16:56 | Fix a problem in the block-sort logic that can arise if the VDBE opcode array is resized while the block-sort logic is being coded. "make test" now runs to completion, though there are still 17 failures. (check-in: 62f3a22050 user: drh tags: orderby-planning) | |
| 15:17 | Avoid reusing temporary registers in co-routines when doing block-sorting. (check-in: 463d921b51 user: drh tags: orderby-planning) | |
| 14:30 | Make sure the where.c query planner never reports that the number of ORDER BY terms that are satisfied by indices is negative. (check-in: b186d8d15a user: drh tags: orderby-planning) | |
| 14:10 | First attempt at getting block-sort to work. This is an incremental check-in. There are many problems still to be worked out. (check-in: 59742dd4c5 user: drh tags: orderby-planning) | |

| 20:33 | Make the partial-ORDER-BY information in the query planner available to the SELECT code generator. Still doesn't make a difference in the generated code. (check-in: e258df236b user: drh tags: orderby-planning) | |
| 18:59 | Adjust the query planner to keep track of the number of ORDER BY terms satisfied. Still doesn't do anything with this information. Some tests fail after this check-in, but all failures are believed to be benign. The failures will be addressed at a later stage. (check-in: 59d49b7fc4 user: drh tags: orderby-planning) | |
| 15:30 | Experiments with the optimization of ORDER BY and GROUP BY clauses. (check-in: b150902579 user: drh tags: orderby-planning) | |

| 20:12 | Adjustments to the cost computation for the skip-scan query plan, to take into account the fact that a seek has to occur on each skip. (check-in: 0769eebd02 user: drh tags: trunk) | |
| 18:03 | Attempt to work around MSVC's treatment of __LINE__ as a non-constant value in "Edit and Continue" mode by avoiding the use of __LINE__ when SQLITE_VDBE_COVERAGE is not defined. (check-in: 0a5318bc27 user: drh tags: trunk) | |

|
2014-03-07

| 14:57 | Improved comment on the pager.c PERSIST rollback journal delete logic inside of hasHotJournal(). No changes to code. (check-in: e5b17a9d07 user: drh tags: trunk) | |
| 03:31 | Revise change from the previous check-in to clarify the situation when handling open journal files, regardless of journal mode. (check-in: 1c318ef3b7 user: mistachkin tags: trunk) | |
| 02:29 | Avoid calling sqlite3OsDelete() on a file that is open, since this causes Windows to run *very* slowly. Comes up on error recovery in journal_mode=PERSIST. (check-in: fdc651e2ec user: mistachkin tags: trunk) | |
|
2014-03-06
| ||

| 13:38 | Improved EXPLAIN indentation of a loop in the ANALYZE logic for STAT4. Mark the not-found jump of a seek operation in that loop as never taken. (check-in: 0a4200f95c user: drh tags: trunk) | |
| 12:36 | Remove a branch that is never taken from where.c. (check-in: 4a4997221f user: dan tags: trunk) | |

| 01:56 | Fix some incorrect comments and typos in comments. Add testcase() macros to some of the new record comparison code. (check-in: b83cfe899d user: drh tags: trunk) | |

| 15:04 | Add a test case for the problem fixed by [1d134ba2ed]. (check-in: d4fbc05df9 user: dan tags: trunk) | |
| 14:40 | When converting a result type from TEXT to BLOB using the sqlite3_value_blob() interface, continue to report SQLITE_TEXT as the true type from sqlite3_value_text() as long as that text is still valid. The maintains legacy behavior from before the noMemType change. (check-in: 1d134ba2ed user: drh tags: trunk) | |
| 12:47 | Separate the column NULL value constant into a separate routine for greater commonality with the sessions branch. (check-in: 12cbebb997 user: drh tags: trunk) | |
