René Cannaò	c15ee49797	Add support for wildcard in mysql_query_rules.client_addr #1450 ... Input validation: - client_addr not longer than INET6_ADDRSTRLEN - % allowed only at the end of client_addr Query rule itself remembers if there is a wildcard or not. If there is a wildcard compares string till the wildcard. If client_addr=='%' , it is a match all.	8 years ago

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

René Cannaò	bc8c5e175a	Added column mirror_flagOUT in mysql_query_rules ... Mirroring starts when either mirror_hostgroup or mirror_flagOUT is set	10 years ago
René Cannaò	2e276f06f4	Second commit to implement mirroring ... Expanded table `mysql_query_rules` to add `mirror_hostgroup` Expanded struct `_Query_Processor_rule_t` and class `Query_Processor_Output` to support `mirror_hostgroup` Added new variable `mirror_hostgroup` in `MySQL_Session` The following logic ensure that a mirror_hostgroup set when processing the query in the original session is preserved when reprocessing the query in the mirror session: * when a new mirror session is *created* `mirror_hostgroup` is set according to the result of Query_Processor * when a mirror session is *executed* , `mirror_hostgroup` is copied into `default_hostgroup` Current limitations: * queries larger than 15MB aren't mirrorred * upgrade from 1.1 is still not possible it will wipe table mysql_query_rules	10 years ago
