# ==== Purpose ====
#
# Verify that calling a function updating temporary table should be
# compatible with FLUSH TABLES WITH READ LOCK (FTWRL) in row binlog
# formart. Which is split from flush_read_lock.test, because we set
# binlog format to statement for writing a 'function call' top
# statement into binary log if the function contains DML statement(s)
# on temporary table in mixed mode after fixing Bug #28258992. Which
# causes an known timeout issue in statement binlog format. So we can
# just run the script in row format.
#
# ==== Implementation ====
#
# 1. If function used as argument updates temporary tables
# CALL statement should be compatible with FTWRL.
# 2. DO which calls SF updating temporary table should be
# compatible with FTWRL.
# 3. SELECT which calls SF updating temporary table should be
# compatible with FTWRL.
# 4. Ordinary SET which calls SF updating temporary table
# should be compatible with FTWRL.
