#***********************************************************************
# 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
