# Bug 12902967: Creating self referencing fk on same index unhandled,
|
|
# confusing error
|
|
#
|
|
# Creating a self referencing foreign key on the same
|
|
# column/index is an unhandled exception, it should throw a sensible
|
|
# error but instead implies that your data dictionary may now be out
|
|
# of sync:
|
|
|
|
--source include/have_innodb.inc
|
|
--source include/not_embedded.inc
|
|
|
|
let error_log= $MYSQLTEST_VARDIR/log/mysqld.1.err;
|
|
--source include/restart_mysqld.inc
|
|
|
|
create table t1 (f1 integer primary key) engine innodb;
|
|
|
|
# The below statement should produce error message in error log.
|
|
# This error message should mention problem with foreign keys
|
|
# rather than with data dictionary.
|
|
--replace_regex /'\.\/test\/#sql-[0-9a-f_]*'/'#sql-temporary'/
|
|
--error ER_ERROR_ON_RENAME
|
|
alter table t1 add constraint c1 foreign key (f1) references t1(f1);
|
|
--source include/restart_mysqld.inc
|
|
perl;
|
|
|
|
$file = "$ENV{'error_log'}";
|
|
open ( FILE, $file) || die "can't open file! ($file)\n";
|
|
@lines = <FILE>;
|
|
close (FILE);
|
|
$count = 0;
|
|
foreach $line (reverse @lines) {
|
|
if ($line =~ "^InnoDB:") {
|
|
++$count;
|
|
print "$line";
|
|
if ($count == 2) {

break;
