+# 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
