| 16:04 | The RTREE extension behaves has if data columns have type REAL, so we should actually declare them as REAL so that automatic indexes handle them correctly. Ticket [e63b4d1a65546532] (Leaf check-in: 85a9b6a9 user: drh tags: trunk) | |

| 17:16 | In sqlite3changeset_apply(), ensure that DELETE and UPDATE changes are always executed on main database tables, not similarly named temp tables, as documented. INSERT statements are already being handled correctly. (check-in: f71a13d0 user: dan tags: trunk) | |

| 11:32 | Ensure that the filename passed into the xFullPathname method of the VFS is acceptable as an argument to sqlite3_uri_parameter().

| ||
| 13:01 | In the OP_Column opcode, if the cursor is marked NullRow (due to being the right table of a LEFT JOIN that does not match) and the cursor is the table cursor for an OR-optimization with a covering index, then do not substitute the covering index cursor, since the covering index cursor does not have the NullRow flag set.

| 11:57 | When determining whether an == or IS constraint in a WHERE clause makes an ORDER BY term redundant, consider the collation sequence used by the == or IS comparison, not the collation sequence of the comparison expression itself.

|
2020-02-03
| ||
| 19:56 | Cosmetic change to the xfer-optimization to put the OP_RowData opcode closer to the corresponding OP_Insert opcode. This makes it slightly easier to read and understand the code. (check-in: 0ea2dbfc user: drh tags: trunk) | |

| 14:40 | Revise the layout of filenames in the Pager object so that it is unchanged from prior versions. It turns out that some important 3rd-party software does questionable pointer manipulations on those filenames that depend on that legacy layout.

| 12:29 | Fix the series.c and spellfix.c extensions to use SQLITE_VTAB_INNOCUOUS correctly. Fix the documentation on sqlite3_vtab_config() to take into account SQLITE_VTAB_INNOCUOUS and SQLITE_VTAB_DIRECTONLY. (check-in: 9265cb7f user: drh tags: trunk) | |

|
2020-01-19
| ||
| 20:37 | Enhancement to the CLI to allow the ".parameter init" command to work even if defensive mode is turned on. (check-in: 4d462550 user: drh tags: trunk) | |
|
2020-01-18

| 22:20 | In the TCL interface, add the ability to change the SQLITE_DBCONFIG_TRUSTED_SCHEMA setting using the "db config" method. (check-in: 1accfa8c user: drh tags: trunk) | |
| 21:34 | Allow non-deterministic function in CHECK constraints. It turns out that PostgreSQL, MySQL, and SQLServer all allow this. We should be the the exception. Ticket [830277d9db6c3ba1] (check-in: 8c8ce526 user: drh tags: trunk) | |
| 19:46 | Do not use memcpy() of zero bytes when initializing a pager. This avoids a warning. (check-in: cca43778 user: drh tags: trunk) | |

|
2020-01-17
| ||
| 23:27 | Fix a typo in a comment. No code changes. (check-in: 4363f69c user: drh tags: trunk) | |
| 21:12 | The compress() function should not be deterministic since the same input can have multiple possible compressed outputs. The uncompress() function, on the other hand, is deterministic. (check-in: 84f31490 user: drh tags: trunk) | |

| 11:18 | Fix a case in "fuzz.test" that could fail, as non-deterministic functions may no longer appear in CHECK constraints. (check-in: a370871e user: dan tags: trunk) | |

|
2020-01-15
| ||
| 16:20 | Do not allow the "PRAGMA encoding" statement to change the database encoding if TEMP content exists, or content in any other attached database. Formerly, encoding changes were allowed if just the main database file was empty. Ticket [a08879a4a476eea9]. (check-in: 03b003c9 user: drh tags: trunk) | |
|
2020-01-14

2020-01-12
| ||
| 22:38 | Better than removing the incorrect assert() is to change it into a testcase() together with a comment indicating where an appropriate test case can be found, and the ticket that provoked the change. Ticket [614b25314c766238] (check-in: 3e3c60d8 user: drh tags: trunk) | |
| 22:25 | Change the zipfile virtual table so that the xBestIndex method gives a reasonable cost estimate even if no filename is specified. The missing filename error continues to be raised in the xFilter method. Meanwhile, the more reasonable cost estimate avoids unnecessary wierdness in the query planner. (check-in: 0e468aa6 user: drh tags: trunk) | |
