# 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
|
|
# on table columns
