-# 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:
-#
-#  drh added on 2014-07-30 12:33:04:

-#  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
