|
2020-10-22
| ||
| 18:50 | Minor tweaks to query planning weights so that when STAT4 is enabled and functioning, a full table scan is more likely to be selected if that seems like the fastest solution.

| 11:55 | For the OP_SeekScan optimization, the OP_IdxGT does not necessarily come right after the OP_SeekGE. So use the P2 operand of OP_SeekScan to point to the first instruction after OP_IdxGT. Problem found by dbsqlfuzz. (check-in: 091d719394 user: drh tags: trunk) | |
| 02:02 | Disable the OP_SeekScan opcode of the in-scan-vs-index optimization when in PRAGMA reverse_unordered_selects mode, as the OP_SeekScan only works with forwards scans. Thanks to OSSFuzz for pointing out the problem to us. (check-in: c75c3a3b75 user: drh tags: trunk) | |

|
2020-09-30
| ||
| 18:06 | Improved query optimization for multi-column indexes where the second or later columns are constrained by an IN operator and the earlier index columns limit the search to a small number of rows. Use the new OP_SeekScan opcode which does scanning of the relevant range of the index but gives up and falls back to doing a seek if the number of rows scanned grows to large, in order to guard against pathological cases where the estimated number of rows to be scanned is far too small. (check-in: 4a43430fd2 user: drh tags: trunk) | |
| 17:32 | Back out the incorrect optimization of check-in [e51ecadcbdef5ce6] as ticket [5c4e7aa793943803] reports a case where the optimization does not work. (check-in: 7395e96b8c user: drh tags: trunk) | |
| 15:36 | In the query flattener when substituting expression Y in place of expression X, if X is marked has having come from an ON or USING clause of a LEFT JOIN, then be sure that all subexpressions of Y, not just the root node of Y, are similarly marked. Otherwise, if Y is an AND operator, it will be split up during WHERE clause analysis and the subexpressions will not get the special treatment needed by LEFT JOIN ON/USING clauses. Fix for ticket [66e4b0e271c47145]. (check-in: 69f9eb7343 user: drh tags: trunk) | |
| 09:17 | Better understanding of savepoint code (check-in: ce6d8d6215 user: shearer tags: trunk) | |

| 18:49 | New test-control that returns the number of calls to sqlite3BtreeMovetoUnpacked() on the main database and then resets the counter. This only works for SQLITE_DEBUG builds. (check-in: dca5b91926 user: drh tags: trunk) | |
| 12:29 | Fix the documentation for the OP_IdxGT family of opcodes to show that the P5 operand is not used. (check-in: 62f7d2a612 user: drh tags: trunk) | |

| 19:07 | Enhance the ".databases" command in the CLI so that it shows the result of sqlite3_db_readonly() and sqlite3_txn_state() for each database file. (check-in: 0ffd16d23d user: drh tags: trunk) | |
| 10:50 | If the argument to the ".read" command in the CLI begins with "|" then run the remainder of the argument as a command and read input from the output of that command. (check-in: 6c716f4b55 user: drh tags: trunk) | |

| 23:44 | Reduce the N in the logN term for the sorting cost associated with computing DISTINCT by B-Tree by half, under the assumption that the DISTINCT will eliminate about half the rows of output. This is really a wild guess. But we do not have any better way of estimating what the row-count reduction due to DISTINCT will actually be. (check-in: 8787417ec1 user: drh tags: trunk) | |
| 10:52 | Correctly handle expressions like "x IS (not) true/false" within the rhs of IN() expressions. Fix for [f3ff1472]. (check-in: 493a25949b user: dan tags: trunk) | |

| 23:51 | Try to make SQLite easier to compiler for Mac Catalyst. See forum post 803387a1c5. (check-in: e1595a20d7 user: drh tags: trunk) | |
| 23:32 | Do not skip over TK_IF_NULL_ROW operators when bypassing TK_COLLATE operators. Fix to check-in [ac31edd3eeafcef4] which was itself a fix for ticket [45f4bf4eb4ffd788]. (check-in: 871f2ddcfb user: drh tags: trunk) | |
| 15:24 | Update releasetest_data.tcl so that the "Fast-One" configuration runs bigmmap.test as part of release testing. (check-in: a0aa35aaa5 user: dan tags: trunk) | |

| 22:23 | Remove more unnecessary sqlite3GetVdbe() calls, replacing them with assert()s. (check-in: b7dc932197 user: drh tags: trunk) | |
| 21:55 | Avoid unnecessary calls to the sqlite3GetVdbe() routine. Add assert() statements to prove each call is unnecessary. (check-in: 86d3790caf user: drh tags: trunk) | |
| 19:58 | Omit the unnecessary not-NULL check on the upper bound of a forward index range scan. The subsequent OP_IdxGT will always catch the NULL. Similarly, omit the not-NULL check on the lower bound of a reverse index range scan, as the SeekLE opcode will disallow the NULL. (check-in: e51ecadcbd user: drh tags: trunk) | |

| 21:51 | When doing an UPDATE or DELETE using a multi-column index where only a few of the earlier columns of the index are useful for the index lookup, postpone doing the main table seek until after all WHERE clause constraints have been evaluated, in case those constraints can be covered by unused later terms of the index, thus avoiding unnecessary main table seeks. (check-in: 7fee0b1075 user: drh tags: trunk) | |
