Using the following regex filter:

[MySetOptionFilter]
type=filter
module=regexfilter
options=ignorecase
match=SET OPTION SQL_QUOTE_SHOW_CREATE
replace=SET SQL_QUOTE_SHOW_CREATE

Sending the following query hangs MaxScale:

SET OPTION SQL_QUOTE_SHOW_CREATE = 1;

This happens because modutil_replace_SQL doesn't modify the SQL packet length if the resulting replacement is shorter.
Comment 1 Markus Mäkelä 2015-02-16 10:27:20 UTC
Added SQL packet length modifications to modutil_replace_SQL when the original length is different from the replacement length.
