# ==== Purpose ====
#
# This test will set a value for binlog_group_commit_sync_delay
# which will be a non multiple of delta(the waiting time is
# broken into smaller chunks called as delta), and execute some
# transactions after that.
#
# The test verifies that server does not hang when a non multiple of 10
# is assigned to binlog_group_commit_sync_delay variable.
#
# Related bugs and Worklogs
#
# Bug#28091735:COMMIT WILL HANG IF BINLOG_GROUP_COMMIT_SYNC_DELAY
#              IS NOT A MULTIPLE OF 10
