| ||
| 18:45 | Merge the OFFSET-on-query-without-FROM fix from trunk. check-in: 71e9ae72c2 user: drh tags: orderby-planning | |
| 18:16 | Fix the OFFSET clause so that it works correctly on queries that lack a FROM clause. Ticket [07d6a0453d4ed8]. check-in: 179ef81648 user: drh tags: trunk | |
| 15:24 | New test case for block-sorting. check-in: e70cfa28aa user: drh tags: orderby-planning | |

| 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 | |
| 18:56 | Only use the direct-overflow-read optimization if all data from the overflow page in question is being read. check-in: d8e1f75ddf user: dan tags: overflow-pgno-cache | |
| 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 | |
| 12:36 | One possible fix for the [e39d032577d] problem it to replace the failing assert() with a testcase() as shown here. Closed-Leaf check-in: eae6dfbe55 user: drh tags: tkt-e39d0325 | |
| 12:17 | Fix an unnecessarily obtuse use of a bitmask flag. check-in: ca31408131 user: drh tags: trunk | |
| 09:42 | Add a test to ensure os_unix.c works with 64KiB OS pages. Closed-Leaf check-in: e3d2be3ba4 user: dan tags: shm-mapping-fix | |
| 08:59 | Add an experimental fix to avoid attempting to mmap memory from an offset that is not a multiple of the system page size on systems with page sizes larger than 32KB. check-in: 6f3a5c24d2 user: dan tags: shm-mapping-fix | |

| 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 | |
|
2014-03-17
| ||
| 15:43 | Add an experimental multi-threaded capability to vdbesorter.c. check-in: ff0b5c851b user: dan tags: threads | |
| 15:06 | Clean up some obsolete "register" declarations in printf.c. check-in: ecd9d3f945 user: drh tags: trunk | |
| 14:24 | Performance enhancements and size reduction for sqlite3VXPrintf() check-in: eb071eb58c user: drh tags: trunk | |
|
2014-03-14
| ||
| 11:46 | Fix a harmless compiler warning that crops up with SQLITE_MAX_MMAP_SIZE=0. check-in: 1277932b7e user: drh tags: trunk | |
|
2014-03-13
| ||
| 15:41 | Merge latest trunk changes into this branch. check-in: d17231b63d user: dan tags: threads | |
|
2014-03-12
| ||
| 19:38 | Fix an obscure bug causing sqlite3_close() to fail if there are virtual tables on the disconnect list when it is called. check-in: 6504aa47a8 user: dan tags: trunk | |
| 19:20 | Changes to FTS to ensure that it does not access the database from within the xConnect method. check-in: c67a52c356 user: dan tags: trunk | |
| 12:44 | Prevent the rtree module from reading sqlite_stat1 data from the wrong database. check-in: 7ce03c1b55 user: dan tags: trunk | |
| 10:03 | Bump the version number to 3.8.4.1., to conform with trunk. check-in: 42c9d8fc5f user: drh tags: sessions | |
|
2014-03-11
| ||
| 23:44 | Remove a stray C99-style comment. check-in: f500e87d6e user: drh tags: overflow-pgno-cache | |
| 23:40 | Combine the various boolean fields of the BtCursor object into a single bit-vector. This allows setting or clearing more than one boolean at a time and makes the overflow-pgno-cache branch faster than trunk on speedtest1. check-in: 968fec44d7 user: drh tags: overflow-pgno-cache | |
| 20:33 | Enable the b-tree cursor object's overflow page-number cache, which is normally enabled only for incr-blob cursors, for all cursors. check-in: da59198505 user: dan tags: overflow-pgno-cache | |
| 15:27 | Version 3.8.4.1 check-in: 018d317b12 user: drh tags: trunk, release, version-3.8.4.1 | |
| 15:25 | Update version number to 3.8.4.1 check-in: 33f5694fa4 user: drh tags: trunk | |
| 14:44 | Forgot to change the VERSION file. Closed-Leaf check-in: 04caffcef3 user: drh tags: mistake | |
| 09:19 | Add a test to see what happens if an rtree constructor encounters an SQLITE_BUSY error. No changes to code. check-in: 5527e23636 user: dan tags: trunk | |
| 01:48 | Version 3.8.4 for sessions (plus two minor fixes). check-in: 917c410808 user: drh tags: sessions | |
|
2014-03-10
| ||
| 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 | |
| 12:20 | Version 3.8.4 check-in: 530a1ee7dc user: drh tags: trunk, release, version-3.8.4 | |

|
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 | |
| 14:36 | Merge the fix for the journal_mode=PERSIST error recovery delay bug. check-in: bb6a75f4bb user: drh tags: sessions | |
| 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 | |
