# ==== Purpose ====
#
# This test will try to rotate the binary log of the server while binary log
# group commit sync stage tries to sync the recently flushed binary log group.
#
# As binary log group commit releases the binary log's LOCK_log right after
# finishing the flush stage and entering the sync stage, the rotate procedure
# (executed by MYSQL_BIN_LOG::new_file_impl) will be able take LOCK_log, but
# it will delay the binary log rotation until the amount of prepared
# transactions not yet committed be zero or the binary log group commit sync
# stage has finished.
