| 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) | |

| 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) | |

| 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) | |
| 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) | |
| 14:44 | Merge recent trunk changes, and especially the fix for the CREATE UNIQUE INDEX problem of ticket [9a6daf340df99ba9]. (check-in: 5b50a8380b user: drh tags: threads) | |
| 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) | |

| 18:53 | Add a couple more assert statements. (check-in: 4e816db235 user: mistachkin tags: threads) | |
| 18:46 | Fix unreachable branches in the threads.c module. (check-in: 3175e366bb user: drh tags: threads) | |
| 18:03 | Merge updates from trunk. (Closed-Leaf check-in: 08c9a4ea63 user: mistachkin tags: winMutex) | |
| 17:22 | Fix a harmless compiler warning. (check-in: 216d21d0e6 user: drh tags: threads) | |
| 16:37 | Make the Win32 thread handles are available after the threads exit. (check-in: 565c5af7a7 user: mistachkin tags: threads) | |
| 15:18 | Fix the threads build on Windows when SQLITE_MAX_WORKER_THREADS is greater than 0. (check-in: f37db3a03d user: drh tags: threads) | |
| 14:16 | Merge the R-Tree fix and the new SQLITE_TESTCTRL_ISINIT test control from trunk. (check-in: b2f7eb3cc2 user: drh tags: threads) | |
| 14:09 | Add the SQLITE_TESTCTRL_ISINIT file control. (check-in: 8b651d4d6c user: drh tags: trunk) | |
| 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) | |

| 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) | |
| 20:14 | Add the "loadfts" program, for performance testing the loading of data into fts3/fts4/fts5 tables. (check-in: 770b9540c1 user: dan tags: fts5) | |
| 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) | |
