01:08 | Fix typos in the opcode documentation. Comment changes only. No changes to code. (check-in: 717245d487 user: drh tags: trunk) | |
00:29 | A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code. The error message is not quite as good, but as this error has apparently not previously occurred in over 8 years of heavy use, that is not seen as a serious problem. (check-in: 0ad1ed8ef0 user: drh tags: trunk) | |
2014-08-05

21:31 | Ensure that aggregate functions are not used when evaluating a default value for a table column. Candidate fix for ticket [3a88d85f36704eebe134f7]. (check-in: 29ba812825 user: drh tags: trunk) | |
19:35 | Use doclist indexes for AND queries as well as phrases. (check-in: 5d38e6edc4 user: dan tags: fts5) | |
19:16 | Add the ability to evaluate IN operators as a sequence of comparisons as an alternative to the long-standing algorithm of building a lookup table. Use the new implementation in circumstances where it is likely to be faster, such as when the RHS of the IN changes between successive evaluations. (check-in: 9528682168 user: drh tags: trunk) | |
19:00 | Use doclist-indexes with "ORDER BY rowid ASC" fts5 queries as well. (check-in: d028ba6589 user: dan tags: fts5) | |
11:04 | Rename the internal Schema.flags field to Schema.schemaFlags. (check-in: 5ae80b3c8f user: drh tags: trunk) | |
00:53 | Improved VdbeCoverage() macros. A few minor simplifications to generated VDBE code. (Closed-Leaf check-in: 01f60027ad user: drh tags: IN-operator-improvements) | |
2014-08-04
| ||
21:26 | Part of the change in the previous check-in was incorrect and can result in an incorrect UPDATE for WITHOUT ROWID tables. This check-in fixes the problem. (check-in: ee5f6eae57 user: drh tags: IN-operator-improvements) | |
20:07 | Fix fts5_index.c to use doclist-indexes when possible. Only some cases work so far. (check-in: 90b82d3ef6 user: dan tags: fts5) | |
18:50 | Further enhancements to IN-operator processing. (check-in: 7fdf26da1d user: drh tags: IN-operator-improvements) | |
16:39 | Refinements to the enhanced IN-operator logic. (check-in: 92ba282146 user: drh tags: IN-operator-improvements) | |
15:12 | Changed my mind: This opcode name changes mere creates unnecessary diff marks between older and newer versions without significantly improving readability. Was: Rename the IsNull opcode to IfNull and rename the NotNull opcode to IfNotNull. (Closed-Leaf check-in: 2f724cbac9 user: drh tags: deadend) | |
2014-08-02
| ||
21:03 | Enhancements to the code generator for the IN operator that result in much faster queries in some cases, for example when the RHS of the IN operator changes for each row of a large table scan. (check-in: 436e884215 user: drh tags: IN-operator-improvements) | |
20:49 | Start changing things to use doclist indexes as required. code is not activated yet. (check-in: b8864da95d user: dan tags: fts5) | |
20:44 | Remove (newly) incorrect preprocessor check to fix build on WinRT. (check-in: ba78265429 user: mistachkin tags: trunk) | |
2014-08-01

21:12 | A better comment on the generated code for the NULL-in-RHS-of-IN detection logic. (check-in: 9bc1c730a3 user: drh tags: trunk) | |
21:00 | Improved detection and handling of NULL values on the RHS of a IN operator. (check-in: 468e730036 user: drh tags: trunk) | |
20:13 | Add a special case to the integrity-check code to check that the final integer in a doclist index is as expected. (check-in: c98934155c user: dan tags: fts5) | |
19:27 | Have the fts5 integrity-check verify that doclist indexes match the contents of the leaf pages that they index. (check-in: 37a7d3035e user: dan tags: fts5) | |
18:00 | Remove an unnecessary OP_Null in the IN-operator logic. Attempt to clarify comments explaining the IN-operator code, though it is not clear that the comments are correct even yet - more work to be done. (check-in: c11e55fabb user: drh tags: trunk) | |
15:51 | Clean up the IN operator code generation logic to make it easier to reason about. In the process, improve code generation to omit some unused OP_Null operations. (check-in: 7c6fbcfe6e user: drh tags: trunk) | |
15:34 | The idea of coding IN operator with a short list on the RHS as an OR expression turns out to be helpful. If the list is of length 1 or 2, the OR expression is very slightly faster, but the ephemeral table approach is clearly better for all list lengths greater than 2. Better to keep the code simple. (Closed-Leaf check-in: e13175d357 user: drh tags: IN-operator-improvements) | |
14:46 | Begin making changes to the IN operator in an attempt to make it run faster and to make the code easier to understand. (check-in: ee0fd6aaf9 user: drh tags: IN-operator-improvements) | |
11:16 | Add "doclist index" records to the database. These are to make navigating within very large doclists faster. They are not yet used by queries. (check-in: 89377421ff user: dan tags: fts5) | |
01:40 | Enhance the PRAGMA integrity_check command to detect UNIQUE and NOT NULL constraint violations. (check-in: 9abcf2698c user: drh tags: trunk) | |
2014-07-31
| ||
22:59 | Refactoring: Change "pIndex->onError!=OE_None" to use a macro: "IsUniqueIndex(pIndex)". Easier to understand that way. (check-in: e75b26ee35 user: drh tags: trunk) | |
20:16 | Omit a pointless OP_Null when processing a value-list RHS of an IN operator where the LHS is a rowid. (check-in: 1361450a9d user: drh tags: trunk) | |
18:54 | Optimizations to the OS sub-type checking in the Win32 VFS. (check-in: 1e5489faff user: mistachkin tags: trunk) | |
18:14 | Add a missing call to "test_sqlite3_log" to multiplex.test. (check-in: 0708f9df23 user: dan tags: trunk) | |
17:53 | Add a comment explaining why fts5 cannot cache "sorter statements". (check-in: e6af3b7a3c user: dan tags: fts5) | |
17:47 | Try to reuse sorter statements in fts5. Does not work due to circular references on VTable object. (Leaf check-in: bc14e64bdf user: dan tags: save_sorter_stmt) | |
17:35 | Fix a leaked database handle in pager2.test. (check-in: 47457b0488 user: dan tags: trunk) | |
15:44 | Deactivate the DISTINCT in a SELECT on the right-hand side of an IN operator, since it should not make any difference in the output but dues consume extra memory and CPU time. (check-in: f4cb53651b user: drh tags: trunk) | |
11:57 | Add further tests for the extension APIs with "ORDER BY rank" queries. (check-in: 37a417d27e user: dan tags: fts5) | |
2014-07-30
| ||
23:11 | Re-integrate the recent changes from the 'winMutex' branch back into the Win32 mutex subsystem. (check-in: 5360ecb0b8 user: mistachkin tags: trunk) | |
21:10 | Add three new static mutexes for use by the application. This is a partial import of changes from the threads branch. (check-in: 3aad01960f user: drh tags: trunk) | |
20:26 | Fix things so that the fts5 extension API works with "ORDER BY rank" queries. (check-in: f1b4e1a98d user: dan tags: fts5) | |
19:41 | Add hidden column "rank". Currently this always returns the same value as the bm25() function. (check-in: 4cc048c365 user: dan tags: fts5) | |
18:47 | Add a new sqlite3FaultSim() call to vdbePmaReaderSeek() to facilitate tests of error handling in the sorter. (check-in: 655d8cfc75 user: drh tags: threads) | |

15:43 | Add the "eForce" parameter to the sqlite3_multiplex_shutdown() entry point in test_multiplex.c. Shutdown is forced if true. Shutdown is not done if there are pending database connections and eForce is false, but an error log entry is made instead. (check-in: c7303d0139 user: drh tags: trunk) | |
14:57 | Merge in the CREATE UNIQUE INDEX fix of ticket [9a6daf340df99ba93c53bcf]. (check-in: fa7912320f user: drh tags: apple-osx) | |

14:29 | Merge the fix for the CREATE UNIQUE INDEX problem into the sessions branch. (check-in: 43401ee624 user: drh tags: sessions) | |
13:56 | Ensure that the correct number of columns in a UNIQUE index are checked for uniqueness, regardless of whether or not the original table has a ROWID or if the columns are NOT NULL, etc. Ticket [9a6daf340df99ba93c]. (check-in: 6b785e92f2 user: drh tags: trunk) | |
11:49 | Merge all recent trunk changes, and especially the R-Tree IN operator fix of ticket [d2889096e7bdeac]. (check-in: 654c6c658b user: drh tags: apple-osx) | |

13:40 | Change the hex literal processing so that only the SQL parser understands hex literals. Casting and coercing string literals into numeric values does not understand hexadecimal integers. This preserves backwards compatibility. Also: Throw an error on any hex literal that is too big to fit into 64 bits. (check-in: 6c6f0de59b user: drh tags: hex-literal) | |

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) | |

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) | |
