| # This file implements regression tests for SQLite library. The |
| # focus of this file is testing the CREATE UNIQUE INDEX statement |
| # to verify that ticket 9a6daf340df99ba93c53bcf8fa83d9f28040d2a8 |
| # has been fixed: |

| # The CREATE UNIQUE INDEX on the third line below does not fail even |
| # though the x column values are not all unique. |
| # |
| # CREATE TABLE t1(x NOT NULL); |
| # INSERT INTO t1 VALUES(1),(2),(2),(3); |
| # CREATE UNIQUE INDEX t1x ON t1(x); |
| # |
| # If the index is created before the INSERT, then uniqueness is enforced |
| # at the point of the INSERT. Note that the NOT NULL on the indexed column |
| # seems to be required in order to exhibit this bug. |
| # |
| # "PRAGMA integrity_check" does not detect the resulting malformed database. |
| # That might be considered a separate issue. |
| # |
| # Bisecting shows that this problem was introduced by the addition of |
| # WITHOUT ROWID support in version 3.8.2, specifically in check-in |
| # [c80e229dd9c1230] on 2013-11-07. This problem was reported on the mailing |
| # list by Pavel Pimenov. and primary keys, and the UNIQUE constraint |
| # on table columns |
