# The test verifies binlogging of XA transaction and state of prepared XA
# as far as binlog is concerned.
#
# The prepared XA transactions can be disconnected from the client,
# discovered from another connection and commited or rolled back
# later. They also survive the server restart. The test runs two
# loops each consisting of prepared XA:s generation, their
# manipulation and a server restart followed with survived XA:s
# completion.
#
# Prepared XA can't get available to an external connection
# until connection that either leaves actively or is killed
# has completed a necessary part of its cleanup.
# Selecting from P_S.threads provides a method to learn that.
