11 # This file implements regression tests for SQLite library. The
12 # focus of this file is testing the CREATE UNIQUE INDEX statement
13 # to verify that ticket 9a6daf340df99ba93c53bcf8fa83d9f28040d2a8

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