# ==== Purpose ====
#
# Verify that 'FLUSH LOGS' does not cause assertion failure any more,
# even if there is no binlog file before executing it.
#
# ==== Implementation ====
#
# 1) SET GLOBAL debug='d,error_unique_log_filename' to
# cause 'FLUSH LOGS' and 'RESET MASTER' commands to error out.
# 2) Execute 'FLUSH LOGS' to verify that it does not cause
# assertion failure any more.

# Test in this file is binlog format agnostic, thus no need
