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
René Cannaò	c101fad268	First draft on mirroring feature ... Add new variable MySQL_Session::mirror (false by default) Add new struct MySQL_Session::mirrorPkt (false by default) These functions return immediately if this is a mirror session: * MySQL_Protocol::generate_pkt_EOF() * MySQL_Protocol::generate_pkt_ERR() * MySQL_Protocol::generate_pkt_OK() * MySQL_Protocol::generate_pkt_column_count() * MySQL_Protocol::generate_pkt_field() * MySQL_Protocol::generate_pkt_row3() MySQL_ResultSet::MySQL_ResultSet() exits almost immediately if this is a mirror session Most of the code of these functions is not executed if this is a mirror session: * MySQL_ResultSet::add_eof() * MySQL_ResultSet::get_resultset() In MySQL_Session::writeout() : * `client_myds->write_to_net_poll()` is called only if this is not a mirror session In MySQL_Session::handler(): * if query is a `SELECT` (hardcoded for now) : ** create a new session and mark it as `mirror=true` ** duplicate the query and send it to the new session * if `mirror==true` : ** pretend to read a new query from c`lient_myds` ** proceed normally (with the only exception that no data can be sent to a client) In MySQL_Thread::process_all_sessions() : * if `mirror==true` and `status==WAITING_CLIENT_DATA` it means the session is "completed" so it get destroyed Limitations: * it currently doesn't support large packets * doesn't support different charset * doesn't support transactions	10 years ago
