| 17:41 | Add the --verify option to speedtest1. Add verification test cases to the "rtree" testset and a case that uses a custom geometry callback. (check-in: 9d485c4207 user: drh tags: rtree-enhancements) | |
| 16:14 | Update comments in the R-Tree module in preparation for some big changes. Add an "rtree" performance test to speedtest1. (check-in: 20a73ec0b2 user: drh tags: rtree-enhancements) | |

2014-04-03
| ||
| 16:35 | Merge all recent changes from trunk, including the fix for the OP_SCopy-vs-OP_Copy problem. (check-in: 9515c8344a user: drh tags: sessions) | |
| 16:29 | Use OP_Copy instead of OP_SCopy when moving results out of a subquery, to prevent the subquery results from changing out from under the outer query. Fix for ticket [98825a79ce1456]. Problem introduced by check-in [1e64dd782a126f48d78]. (check-in: d5513dfa23 user: drh tags: trunk) | |
| 16:16 | Use OP_Copy instead of OP_SCopy when moving results out of a subquery, to prevent the subquery results from changing out from under the outer query. Fix for ticket [98825a79ce1456]. Problem introduced by check-in [1e64dd782a126f48d78]. (check-in: ec6a06246e user: drh tags: branch-3.8.4) | |
| 14:31 | Fix a typo in the "Synopsis:" comment for the OP_VFilter opcode. (check-in: 48ecdd4aff user: drh tags: trunk) | |
| 00:32 | In the command-line shell, run set writable_schema before running the ".clone" command. (check-in: 9d2ae6342c user: drh tags: trunk) | |

| 13:42 | Avoid a (harmless) buffer overread that is possible on an OOM when MEMSYS5 is engaged. (check-in: b3296267fb user: drh tags: trunk) | |
|
2014-03-28
| ||
| 14:41 | Disable the wal64k.test script for non-unix systems since it depends on unix-only features. (check-in: 27deb6e49b user: drh tags: trunk) | |
| 12:56 | Fix a harmless compiler warning. (check-in: a4e47150f3 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: 7fa85eaaaf user: drh tags: trunk) | |
|
2014-03-27
| ||
| 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: 9b4d7226bc user: drh tags: trunk) | |
| 14:05 | Enhance the logest.c utility with new operators: "dup", "inv", "log", and "nlogn". Provide help on an invalid input. (check-in: b4bd2a062c user: drh tags: trunk) | |
|
2014-03-26
| ||
| 19:43 | Merge in fixes (including the corrupt-database crash fix) and performance enhancements from trunk. (check-in: fc8ca1a87e user: drh tags: sessions) | |
| 15:14 | Add an extra test case for the potential buffer overread patched by [28ddecff04]. (check-in: f585f5d7a0 user: dan tags: trunk) | |
| 15:05 | Add a test case to verify that the previous change avoids excess buffer overread in sqlite3VdbeRecordCompare(). (check-in: 2b28e8d582 user: drh tags: trunk) | |
| 14:51 | Earlier detection of corruption in sqlite3VdbeRecordCompare() in order to avoid a potential buffer overread. (check-in: 28ddecff04 user: drh tags: trunk) | |
| 12:02 | Add an assert() and a comment to clarify the operation of the vdbeRecordCompareInt() routine. (check-in: 851abdb8fd user: drh tags: trunk) | |
|

| 20:28 | Adjust the repeat counts on several tests in speedtest1 so that the relative time spent on the test is roughly the same regardless of --size. (check-in: 7922809ee0 user: drh tags: trunk) | |
| 17:45 | Add another performance test case to speedtest1. This case is another ORDER BY test but this time without LIMIT. (check-in: 9ab7ffd592 user: drh tags: trunk) | |
| 14:54 | Add an ORDER BY test case to speedtest1.c (check-in: 588122641e user: drh tags: trunk) | |
| 11:00 | Detect when a VdbeCursor is still pointing at a valid row but that row has moved, and invalidated the return from prior sqlite3BtreeDataFetch() or sqlite3BtreeKeyFetch() calls. (check-in: e6798871ce user: drh tags: trunk) | |
|
2014-03-24
| ||
| 16:30 | Remove unused variables Parse.nColCache and Parse.iColCache. (check-in: 4d7551ce46 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: 221f8f9447 user: drh tags: trunk) | |
| 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: db7d62c8d5 user: dan tags: trunk) | |
|
2014-03-23
| ||
| 16:29 | Avoid a possible use of an uninitialized variable following an I/O or OOM error. (check-in: 641408a139 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: 9b2838f23e user: drh tags: trunk) | |
| 01:52 | Increase the version number to 3.8.5. (check-in: 9760879d08 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: c36f74611c 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: fa06a6fed9 user: drh tags: trunk) | |
| 19:56 | Change the names of SRT_DistTable and SRT_Table used by CTE to more meaningful SRT_DistFifo and SRT_Fifo, respectively. Simplify the IgnorableOrderby() macro in the process. (check-in: 45d8cc678d user: drh tags: trunk) | |
| 19:27 | Avoid leaking memory in an obscure case where the flattener adds an ORDER BY clause to the recursive part of a recursive query. (check-in: 1f413aca00 user: dan tags: trunk) | |
| 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) | |
|
2014-03-20
| ||
| 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) | |
| 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) | |
