12:33
Cancel column-cache entries that are involved in a comparison operator since the comparison might have forced an affinity change. Originally proposed as a fix for ticket [a8a0d2996a], but later determined to be incorrect. Closed-Leaf check-in: 0b95b7a8 user: drh tags: tkt-a8a0d2996a

16:29
Avoid a possible use of an uninitialized variable following an I/O or OOM error. check-in: 641408a1 user: drh tags: trunk
2014-03-22
02:19
Clear the sort-order flags on the KeyInfo object associated with the OP_Compare/OP_Jump of the block-sort logic, in order to make the OP_Jump fully testable. check-in: 9b2838f2 user: drh tags: trunk
01:52
Increase the version number to 3.8.5. check-in: 9760879d user: drh tags: trunk
00:27
Fix the ORDER BY optimization logic so that it will do a block-sort on a partial DESC ORDER BY. This enhancement uncovered a memory leak in pushUntoSorter() which is also fixed. check-in: c36f7461 user: drh tags: trunk
2014-03-21
20:58
Add the ability to use indices for the first few terms of an ORDER BY clause, then sort in batches to handle the later terms. check-in: fa06a6fe user: drh tags: trunk

20:56
Merge trunk fixes for "x IN (?)" handling. check-in: eca35871 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: d5a1530b 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: d8e1f75d 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: 01944c53 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: 2ea4a9f7 user: drh tags: trunk
15:14
Fix harmless compiler warnings. check-in: b1435f26 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: 2ff3b25f 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: e68b427a 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: eae6dfbe user: drh tags: tkt-e39d0325
12:17
Fix an unnecessarily obtuse use of a bitmask flag. check-in: ca314081 user: drh tags: trunk

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: 6f3a5c24 user: dan tags: shm-mapping-fix
2014-03-19
23:42
Merge the vdbesort.c optimization from trunk. check-in: e4bfffb9 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: 01afbf97 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: 707ea170 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: 7ce2daaf 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: 62f3a220 user: drh tags: orderby-planning
15:17
Avoid reusing temporary registers in co-routines when doing block-sorting. check-in: 463d921b 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: b186d8d1 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: 59742dd4 user: drh tags: orderby-planning
2014-03-18
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: e258df23 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: 59d49b7f user: drh tags: orderby-planning
15:30
Experiments with the optimization of ORDER BY and GROUP BY clauses. check-in: b1509025 user: drh tags: orderby-planning

Remove a stray C99-style comment. check-in: f500e87d 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: 968fec44 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: da591985 user: dan tags: overflow-pgno-cache

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: 0769eebd 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: 0a5318bc 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: 1c318ef3 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: fdc651e2 user: mistachkin tags: trunk
2014-03-06
18:16
Do not run corruptH.test in mmap mode. check-in: c0d54b4e user: dan tags: trunk

Fix a harmless compiler warning in the sessions test harness. check-in: d389e20a user: drh tags: sessions
14:53
Enhance the test harness for the sessions interface so that it does not use SQLite operations that can encounter an OOM error in places where it is unable to report an OOM error back up to the test script. check-in: bc0e6610 user: drh tags: sessions
13:48
Merge the latest 3.8.4 tweaks from trunk. check-in: 1ed463d9 user: drh tags: sessions

12:36
Remove a branch that is never taken from where.c. check-in: 4a499722 user: dan tags: trunk

Reduce the number of cases where it is necessary to check for NULL after the loop terminating condition. check-in: 3c1ae447 user: drh tags: trunk
15:13
Add OP_IdxGT and OP_IdxLE as distinct opcodes. Formerly these operations where done using OP_IdxGE and OP_IdxLT with the P5 flag set. But VDBE code is easier to read with distinct opcode names.

Minor simplifications to the "zeroPage()" routine in btree.c. check-in: cc8f10bc user: drh tags: trunk
21:31
Remove the "rowid cache" that sought to remember the largest rowid for a table and thereby speed up OP_NewRowid. That cache was ineffective. Removing it results in a performance increase of 0.4%, less memory usage, and a slightly smaller library size. check-in: 56bc5ce8 user: drh tags: trunk
14:43
Make sure "rowid" columns are correctly resolved in joins between normal tables and WITHOUT ROWID tables. Fix for ticket [c34d0557f740c45070]. check-in: 5d01426d user: drh tags: trunk

Do not mark the ephemeral tables used to hold the RHS of IN clauses as unordered because the NGQP will use those ephemeral tables to help order the output. This is not an issue for standard SQLite since ephemeral tables there are always ordered, regardless of the hint. It only affects systems that substitute an alternative storage engine. check-in: f2504089 user: drh tags: trunk
20:46
Remove the SF_Materialize flag from the SELECT object as it does not accomplish anything useful. check-in: 65d5dcdd user: drh tags: trunk

Change the recursive common table expression algorithm to use a queue instead of a pair of tables. Runs about 25% faster on the sudoku solver query. The OP_SwapCursors opcode is no longer required. The current implementation uses just a fifo, but the plan is to change it into a queue that will support ORDER BY and LIMIT in a recursive query. check-in: b2671e11 user: drh tags: cte-via-queue
15:04
Remove the undocumented requirement for applications that use an SQLITE_ENABLE_SQLLOG build to define a sqlite3_init_sqllog() function. check-in: 5e43bf01 user: dan tags: trunk
2014-01-20
