# ==== Purpose ====
#
# If a server is crashed after preparing a XA transaction and right before
# committing the XA transaction, which is used to select from the system
# gtid_executed table explicitly by users, verify that the following
# recovery is not aborting due to an innodb_lock_wait_timeout error
# when it is reading the system gtid_executed table.
#
# ==== Implementation ====
#
#  - Start a XA transaction and select from the mysql.gtid_executed
#    table explicitly.
#  - Check the ER_ERROR_ON_MODIFYING_GTID_EXECUTED_TABLE error is not caused.
#  - Crash the server after preparing a XA transaction and right before
#    committing the XA transaction.
#  - Verify that the following recovery is not aborting due to an
#    innodb_lock_wait_timeout error when it is reading the system
#    gtid_executed table.
