+# Due to https://bugs.mysql.com/bug.php?id=115953, in Mysql 8, if ANSI_QUOTES is enabled,
+# backticks will be used instead of double quotes to quote functions or procedures name.
+# As a consequence, mysql_user and mysql_roles will always report "changed" for functions
+# and procedures no matter the privileges are granted or not.
+# Workaround for the mysql bug 116953 is removing ANSI_QUOTES from the module's session 
+# sql_mode. But because issue 671, ANSI_QUOTES is always got from GLOBAL sql_mode, thus 
+# this workaround can't work. Even without the Mysql bug, because sql_mode in session 
+# precedes GLOBAL sql_mode. we should check for sql_mode in session variable instead of 
+# the GLOBAL one.
