René Cannaò	4188d2009c	mysql_query_rules.OK_msg #1045 ... Extending mysql_query_rules with a new field: OK_msg If OK_msg is not NULL, an OK packet is sent to the client with an optional message as specified in OK_msg itself. If OK_msg is an not NULL empty string, an OK packet is sent to the client without any message. If both error_msg and OK_msg are present, error_msg is returned. This commit includes also few minor bugs, mostly related to typo that would prevent online upgrade of mysql_query_rules from early release of 1.4.0 .	9 years ago

Christopher Troup	0f75916a2e	Ensure that users num_connections_used doesn't get incremented if connection rejected ...
