# Bug #18734396 INNODB IN-PLACE ALTER FAILURES BLOCK FUTURE ALTERS
|
|
#
|
|
# Temporary tablename will be unique. This makes sure that future
|
|
# in-place ALTERs of the same table will not be blocked due to
|
|
# temporary tablename.
|
|
# Crash the server in ha_innobase::commit_inplace_alter_table()
|
|
CREATE TABLE t1 (f1 INT NOT NULL, f2 INT NOT NULL) ENGINE=innodb;
|
|
SET debug='d,innodb_alter_commit_crash_before_commit';
