# Testing of atomic create table with crashes in a lot of different places
#
# Things tested:
# With myisam and InnoDB engines to ensure that cover both normal and
# online alter table paths.
# Alter table with new columns
# Alter table which only touches .frm
# Alter table disable keys (has it own code path)
# Alter table with rename
# Alter table with rename and only options that touches .frm
# Alter table with rename and add new columns
# Alter table with storage engine change (with and without column definition
# changes)
# Alter table with storage engine change and rename
# Alter table to another database
