Avoid a (harmless) buffer overread that is possible on an OOM when MEMSYS5 is engaged. check-in: b3296267 user: drh tags: trunk

Fix a harmless compiler warning. check-in: a4e47150 user: drh tags: trunk
03:12
Enhance the sqlite3VdbeRecordCompare() routines so that if they encounter database corruption, they will set the UnpackedRecord.isCorrupt field and return 0. The sqlite3BtreeMovetoUnpacked() routine detects this and returns SQLITE_CORRUPT, causing the corruption to be reported back to the top-level. check-in: 7fa85eaa user: drh tags: trunk

Instead of allocating a single large buffer at the beginning of each sort operation, start with a small buffer and extend it using realloc() as required. check-in: 81987c8c user: dan tags: orderby-planning
18:36
Minor cleanup of the code in the query planner that computes the costs estimates for the various plans. There are no changes to the costs at this time. But the code is slightly more readable now and that might facilitate future enhancements. check-in: 9b4d7226 user: drh tags: trunk
17:23
Use xFetch() to access temporary files in vdbesort.c. Use a single large allocation instead of many small allocations when accumulating records in vdbesort.c. This is an interim commit - it allocates a buffer the size of the page-cache every time data is sorted. check-in: f4ac1bf2 user: dan tags: orderby-planning

Fix arithmetic operators so that they do not change the affinity of their input operands. Ticket [a8a0d2996a]. check-in: 221f8f94 user: drh tags: trunk
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

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

Increase the version number to 3.8.5. check-in: 9760879d user: drh tags: trunk

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

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

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

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
