| 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) | |
| 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) | |

| 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) | |
| 20:44 | Remove (newly) incorrect preprocessor check to fix build on WinRT. (check-in: ba78265429 user: mistachkin tags: trunk) | |

| 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) | |
| 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) | |
| 01:40 | Enhance the PRAGMA integrity_check command to detect UNIQUE and NOT NULL constraint violations. (check-in: 9abcf2698c user: drh tags: trunk) | |

| 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) | |
| 17:35 | 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) | |

| 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) | |
| 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) | |
| 17:21 | Mark some invariants in the vdbesort.c logic when SQLITE_MAX_WORKER_THREADS==0. (check-in: 721cd96585 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) | |

| 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) | |

| 12:40 | Merge recent trunk changes, and especially the fix for the R-Tree problem described in ticket [d2889096e7bdeac6]. (check-in: 8f1beeade0 user: drh tags: sessions) | |
| 11:54 | Have calls to the xFilter() method of rtree virtual tables ensure that cursor is initialized before proceeding. Fix for [d2889096e7bdeac]. (check-in: 8cc41b0bf3 user: dan tags: trunk) | |
| 05:49 | Enhancements and updates to the Win32 mutex subsystem. (check-in: 18984c3210 user: mistachkin tags: winMutex) | |

| 20:16 | Remove an unnecessary parameter from vdbeMergeEngineStep(). Rename a couple other routines to be more descriptive of what they do. (check-in: f2407a40f3 user: drh tags: threads) | |
| 19:58 | Rename vdbeIncrMergerInit() to vdbeMergeEngineInit() - a much more accurate name. (check-in: 5b084a2dd5 user: drh tags: threads) | |
| 18:57 | In vdbesort.c, rename vdbeSorterDoCompare() to vdbeMergeEngineCompare() and move it closer to the one place where it is called. Other minor comment changes. (check-in: 09d50d9f0f user: drh tags: threads) | |
| 17:18 | In vdbesort.c, rename all pointers to sqlite3_file objects "pFd" and use the name "pFile" only for pointers to SortFile objects. Other comment enhancements. (check-in: 518290a7fc user: drh tags: threads) | |
