28 check-ins using file src/vdbeaux.c version 5078ca7d
2014-03-25
| ||
17:07 | Fix a problem in the code added by [707ea170b3] causing vdbesort.c to sort unstably. (check-in: d3e640af user: dan tags: orderby-planning) | |
15:04 | Remove the sequence values from sorter records used by ORDER BY as well. (check-in: c3ae3697 user: dan tags: orderby-planning) | |
2014-03-24
| ||
20:19 | Omit the sequence value from sorter records used by GROUP BY queries that cannot use an index. (check-in: 3f90abdd user: dan tags: orderby-planning) | |
18:08 | Avoid unnecessary moving of content between registers during an ORDER BY. (check-in: 4f472acc user: drh tags: orderby-planning) | |
16:30 | Remove unused variables Parse.nColCache and Parse.iColCache. (check-in: 4d7551ce user: dan tags: trunk) | |
15:00 | 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) | |
11:23 | 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: db7d62c8 user: dan tags: trunk) | |
09:34 | Remove an unnecessary temporary register allocation. (check-in: 5d506743 user: dan tags: orderby-planning) | |
02:20 | Remove a pointless OP_Once operation in ORDER BY clauses with LIMIT. (check-in: e6c59d23 user: drh tags: orderby-planning) | |
01:43 | Further enhancements to generated VDBE code for ORDER BY. (check-in: e7188fad user: drh tags: orderby-planning) | |
2014-03-23
| ||
18:47 | merge fixes from trunk (check-in: faf7f9ca user: drh tags: orderby-planning) | |
17:45 | Use only a single OP_MakeRecord instead of two when constructing entries to go onto a sorter. (check-in: d696cded user: drh tags: orderby-planning) | |
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) | |
18:45 | Merge the OFFSET-on-query-without-FROM fix from trunk. (check-in: 71e9ae72 user: drh tags: orderby-planning) | |
15:24 | New test case for block-sorting. (check-in: e70cfa28 user: drh tags: orderby-planning) | |
2014-03-20
| ||
20:56 | Merge trunk fixes for "x IN (?)" handling. (check-in: eca35871 user: drh tags: orderby-planning) | |
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) | |
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) | |
