    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
    14  # has been fixed:

    18  #  The CREATE UNIQUE INDEX on the third line below does not fail even
    19  #  though the x column values are not all unique.
    20  #
    21  #     CREATE TABLE t1(x NOT NULL);
    22  #     INSERT INTO t1 VALUES(1),(2),(2),(3);
    23  #     CREATE UNIQUE INDEX t1x ON t1(x);
    24  #
    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.
    28  #
    29  # "PRAGMA integrity_check" does not detect the resulting malformed database.
    30  # That might be considered a separate issue.
    31  #
    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
