# Bug#42438: Crash ha_partition::change_table_ptr
|
|
# Test when remove partitioning is done while drop table is waiting
|
|
# for the table.
|
|
# After MDL was introduced, there is no longer any race, so test is done
|
|
# by adding a small sleep to verify that the delete waits. This happens
|
|
# only until ALTER tries to upgrade its MDL lock, which ends up in MDL
|
|
# deadlock which is correctly reported.
