| 20:05 | Remove an unnecessary conditional. (Closed-Leaf check-in: 7473c4df user: drh tags: query-plan-experiments) | |
| 19:57 | Add the SQLITE_MAX_WORKER_THREADS compile time option. And the SQLITE_CONFIG_WORKER_THREADS sqlite3_config() switch. (check-in: 2774710d user: dan tags: threads) | |
| 19:49 | Also make sure an index that is a proper subset of some other index has a higher cost than that other index. Add test cases. (check-in: b7830d23 user: drh tags: query-plan-experiments) | |
| 18:24 | Make sure that an index that covers a proper superset of the WHERE clause terms of some other index has a lower cost than the other index. (check-in: ea8b0910 user: drh tags: query-plan-experiments) | |
| 16:53 | • Edit [83a105c864247a02|83a105c8]: Move to branch threads-closed. (artifact: b3cbb445 user: dan) | |
| 16:53 | • Edit [83a105c864247a02|83a105c8]: Mark "Closed". Add tag "threads-closed". (artifact: a4ca9392 user: dan) | |
| 13:42 | Avoid a (harmless) buffer overread that is possible on an OOM when MEMSYS5 is engaged. (check-in: b3296267 user: drh tags: trunk) | |
|
2014-03-29
| ||
| 21:16 | Experiments in picking better query plans, especially when the usage of one index is a subset of another. (check-in: 8f869ca7 user: drh tags: query-plan-experiments) | |
| 19:48 | Changes to make the multi-threaded sorter sort stably. (Closed-Leaf check-in: 83a105c8 user: dan tags: threads-closed) | |
| 10:01 | Fix a broken assert() in vdbesort.c. (check-in: 18d1b402 user: dan tags: threads) | |
| 09:34 | Fix a problem in vdbesort.c causing spurious SQLITE_NOMEM errors when using memsys3 or memsys5. (check-in: a683c05f user: dan tags: threads) | |
| 06:27 | Add the optimization to avoid some unnecessary calls to sqlite3VdbeRecordUnpack() added to the trunk by [707ea170b3]. (check-in: fc4d04e6 user: dan tags: threads) | |
|
2014-03-28
| ||
| 19:47 | Fix a compiler warning and an after-OOM memory leak. (check-in: 58f7ca29 user: drh tags: orderby-planning) | |
| 19:18 | Merge latest changes from orderby-planning branch. (check-in: 4c7fb542 user: dan tags: threads) | |
| 18:35 | Merge the latest changes from trunk. (check-in: 3047a25f user: drh tags: orderby-planning) | |
| 14:41 | Disable the wal64k.test script for non-unix systems since it depends on unix-only features. (check-in: 27deb6e4 user: drh tags: trunk) | |
| 12:56 | 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) | |
|
2014-03-27
| ||
| 19:25 | 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) | |
| 14:05 | Enhance the logest.c utility with new operators: "dup", "inv", "log", and "nlogn". Provide help on an invalid input. (check-in: b4bd2a06 user: drh tags: trunk) | |
| 00:09 | Merge the latest trunk changes and the fix for the crash on a corrupt database. (check-in: 0b35346c user: drh tags: orderby-planning) | |
|
2014-03-26
| ||

| 19:43 | Merge in fixes (including the corrupt-database crash fix) and performance enhancements from trunk. (check-in: fc8ca1a8 user: drh tags: sessions) | |
| 18:51 | Version 3.8.4.2 (check-in: 02ea1663 user: drh tags: release, version-3.8.4.2, branch-3.8.4) | |
| 16:25 | Increase the version number to 3.8.4.2. (check-in: 59978a2e user: drh tags: branch-3.8.4) | |
| 16:22 | Fix a potential buffer overread that could have occurred when searching a corrupt database file. (check-in: db293547 user: drh tags: branch-3.8.4) | |
| 15:14 | Add an extra test case for the potential buffer overread patched by [28ddecff04]. (check-in: f585f5d7 user: dan tags: trunk) | |
| 15:05 | Add a test case to verify that the previous change avoids excess buffer overread in sqlite3VdbeRecordCompare(). (check-in: 2b28e8d5 user: drh tags: trunk) | |
| 14:51 | Earlier detection of corruption in sqlite3VdbeRecordCompare() in order to avoid a potential buffer overread. (check-in: 28ddecff user: drh tags: trunk) | |
| 12:02 | Add an assert() and a comment to clarify the operation of the vdbeRecordCompareInt() routine. (check-in: 851abdb8 user: drh tags: trunk) | |
|
2014-03-25
| ||
| 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: 7922809e user: drh tags: trunk) | |
| 18:29 | Merge enhancements and fixes from trunk. (check-in: e005f2d6 user: drh tags: orderby-planning) | |
| 17:45 | Add another performance test case to speedtest1. This case is another ORDER BY test but this time without LIMIT. (check-in: 9ab7ffd5 user: drh tags: trunk) | |
| 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) | |
| 14:54 | Add an ORDER BY test case to speedtest1.c (check-in: 58812264 user: drh tags: trunk) | |
| 14:12 | Enable four sorting threads by default in the command-line shell. (check-in: 1cab8357 user: drh tags: threads) | |
| 13:17 | Merge all fixes and enhancements from trunk. (check-in: b415dfb6 user: drh tags: threads) | |
| 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: e6798871 user: drh tags: trunk) | |
|
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) | |
| 15:02 | • Fixed ticket [a8a0d299]: Incorrect column data type reported plus 3 other changes (artifact: 7badd139 user: drh) | |
| 15:01 | • Edit [0b95b7a8748df19a|0b95b7a8]: Mark "Closed". Edit check-in comment. (artifact: 0445642a user: drh) | |
| 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) | |
| 12:55 | • Ticket [a8a0d299] Incorrect column data type reported status still Open with 4 other changes (artifact: a8a9f0a1 user: drh) | |
| 12:46 | • Edit [0b95b7a8748df19a|0b95b7a8]: Move to branch tkt-a8a0d2996a. (artifact: 1b6c1c41 user: drh) | |
| 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) | |
| 11:32 | • Ticket [a8a0d299] Incorrect column data type reported status still Open with 6 other changes (artifact: 533558fc user: drh) | |
| 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) | |

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) | |
| 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: 45d8cc67 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: 1f413aca user: dan tags: trunk) | |
| 18:45 | Merge the OFFSET-on-query-without-FROM fix from trunk. (check-in: 71e9ae72 user: drh tags: orderby-planning) | |
| 18:16 | • Fixed ticket [07d6a045]: OFFSET ignored if there is no FROM clause plus 5 other changes (artifact: 9c43cbdc user: drh) | |
| 18:16 | Fix the OFFSET clause so that it works correctly on queries that lack a FROM clause. Ticket [07d6a0453d4ed8]. (check-in: 179ef816 user: drh tags: trunk) | |
| 18:04 | • New ticket [07d6a045] OFFSET ignored if there is no FROM clause. (artifact: c9ba18a7 user: drh) | |
| 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) | |
| 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) | |
| 13:32 | • Edit [eae6dfbe5535f481|eae6dfbe]: Mark "Closed". (artifact: 5d2bec0f user: drh) | |
| 13:31 | • Fixed ticket [e39d0325]: Assertion fault on a query containing "x IN (?)" plus 6 other changes (artifact: 8a7c5a08 user: drh) | |
| 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) | |
| 11:52 | • New ticket [e39d0325] Assertion fault on a query containing "x IN (?)". (artifact: c3311ddb user: drh) | |
| 09:42 | Add a test to ensure os_unix.c works with 64KiB OS pages. (Closed-Leaf check-in: e3d2be3b 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: 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) | |
|
2014-03-17
| ||
| 15:43 | Add an experimental multi-threaded capability to vdbesorter.c. (check-in: ff0b5c85 user: dan tags: threads) | |

| 15:41 | Merge latest trunk changes into this branch. (check-in: d17231b6 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: 6504aa47 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: c67a52c3 user: dan tags: trunk) | |
| 12:44 | Prevent the rtree module from reading sqlite_stat1 data from the wrong database. (check-in: 7ce03c1b user: dan tags: trunk) | |

|
2014-03-11
| ||
| 23:44 | 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) | |
| 20:34 | • Edit [da59198505990a4f|da591985]: Edit check-in comment. (artifact: d21fe9a6 user: dan) | |
| 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) | |
