# The test verifies a few server/engine recovery option combinations.
|
|
# Specifically, MDEV-13437,13438 are concerned with no crashes
|
|
# due to InnoDB being read-only during --tc-heuristic-recover=ROLLBACK|COMMIT.
|
|
#
|
|
# Initially the test commits a transaction and in the following proceeds
|
|
# throughout some phases.
|
|
# Within them the server is shut down and attempted to restart, to succeed
|
|
# that in the end.
|
|
# All this proves no crashes and effective rollback of the transaction.
