# This test script is to check the behaviour of applying XA transaction from
# a binlog dump if the XA transaction split across binary logs.
#
# Steps to reproduce:
# 1) Reset the master and set max_binlog_size to a smaller value 4KB.
# 2) Start a XA transaction which is more than max_binlog_size (4KB).
# 3) Prepare the XA trx.
# (trx content will be written to master-bin.000001 and the binlog
# will be rotated because of the size limit).
# 4) Commit the XA trx (commit will be written to binlog2).
# 5) Save the binlog dump for the reapply purpose.
# 6) Cleanup the server and make it ready to apply the binlog dump.
# 7) Apply the binlog dump.
# 8) Verify that the old data is restorted properly without any issues.
# 9) Cleanup.
