| 16:57 | Fix a problem causing SQLite to return false "foreign key violation" errors when there is a partial (i.e. WHERE constrained) UNIQUE index on the parent key columns. This bug did not cause SQLite to allow illegal data to be inserted into the database, only to reject legal operations. (check-in: 850877d1 user: dan tags: trunk) | |
| 14:32 | Make the sqlite3PagerGet() interface into a virtual method, with different implementations based on the current state of the pager. This gives a small performance increase by avoiding unnecessary branches inside the various methods. (check-in: df5bb90d user: drh tags: pager-get-method) | |
