| 13:57 | Merge enhancements from trunk. check-in: 9e10d88b user: drh tags: apple-osx | |
| 13:51 | On the first connection to a WAL-mode database that was not cleanly shut down and contains a left-over -shm file, truncate the -shm file to 3 bytes instead of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file. Such a rogue process might think it is being helpful by cleaning up old files, but there is a race condition that can cause damage to the database. check-in: 90cf32cd user: drh tags: trunk | |

| 20:09 | When the left-hand side of a WHERE clause contraint is a UNIQUE column, and that term of the WHERE clause is not used for indexing, assume that the term reduces the number of output rows by half. This is one proposed fix for ticket [e8b674241947eb3ba4] Leaf check-in: 5c243eec user: drh tags: unique-constraint-weights | |

2018-10-04
| ||
| 18:17 | The 0x8000 optimization flag associated with SQLITE_TESTCTRL_OPTIMIZATIONS causes a large penalty (200) to be added to all sorting costs, which encourages the query planner avoid using the sorter. This flag can be used in experiments to help come up with a more accurate estimate of the true cost of sorting. Leaf check-in: 857a1b01 user: drh tags: query-planner-debug | |

| 23:57 | Small performance optimization in the JSON parser of Geopoly. check-in: fb520e71 user: drh tags: trunk | |
| 20:37 | Enhance the GeoPOLY extension so that it always stores its polygons in the binary format, which is faster and more compact. check-in: dc35f7b1 user: drh tags: trunk | |
| 20:20 | Ensure that the OP_VColumn opcode does set sqlite3_vtab_nochange() unless the OPFLAG_NOCHNG bit is set in P5. Fix for ticket [69d642332d25aa3b7315a6d385] check-in: 322ab1fc user: drh tags: trunk | |

| 20:48 | Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index. Enable the legacy behavior by default when running the xRename method of virtual tables. check-in: 31dc8b19 user: drh tags: branch-3.25 | |
