| 12:05 | Update the version number to 3.35.5. (check-in: d917b70a user: drh tags: branch-3.35) | |
|
2021-04-18
| ||
| 06:03 | Ensure that all records are updated by setting the OPFLAG_SAVEPOSITION flag when updating records as part of ALTER TABLE DROP COLUMN. Fix for [c88f3036a2]. (check-in: 11c368f2 user: dan tags: branch-3.35) | |
| 05:52 | Modify the drop column code to handle WITHOUT ROWID tables for which a single column appears more than once in the primary key. (check-in: cfa8912a user: dan tags: branch-3.35) | |
|
2021-04-13
| ||
| 18:39 | Fix a problem with handling expressions like "(col IS NULL AND <expr1>) OR col == NULL" in WHERE clauses. Reported at https://sqlite.org/forum/forumpost/1c4f2fdcc4. (check-in: e8c7bd34 user: drh tags: branch-3.35) | |

|
2021-03-19

| 16:13 | Change the sqlite3.pDfltColl (the default collating sequence for the database connection) so that it is the collating sequence appropriate for the database encoding, not the UTF8 collating sequence. This helps to ensure that the database encoding collation is always used, even for expressions that do not have an defined collating sequence. Ticket [1b8d7264567eb6fc].

| 13:54 | Extra zero terminators on the end of the blank filename returned by sqlite3PagerFilename() for an in-memory database. This helps the result work better with sqlite3_filename_journal() and similar functions. (check-in: 63e533d2 user: drh 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().

This backs out the SQLITE_ACCESS_SYMLINK value but adds the new SQLITE_OK_SYMLINK return code from the xFullPathname method of sqlite3_vfs when that routine resolves symbolic links. O_NOFOLLOW is always included in open() system calls for journal files. (check-in: 6a64fb6a user: drh tags: trunk) | |
