René Cannaò	a6c53d0d12	Revert "Refactor header includes."	9 years ago
Maxim Bublis	30dbcc21a8	Refactor header includes. ... * reduce build time by 25%; * remove circular dependency on `cpp.h` and other headers. * fixes issue with `my_global.h` from mariadbclient which redefines `__attribute__`, that leads to broken STL and GCC intrinsics if `<algorithm>` wasn't included prior including this header; * fixes another issue with redefined `__attribute__` which leads to `_conn_exchange_t` not being aligned to cache line size; * removes `pthread_setstacksize` calls as `my_global.h` redefines `pthread_setstacksize` to be `pthread_dummy(0)` which led to stack size being never adjusted; * add missing include guards to some headers; * remove unused proxysql_hash.h header.	9 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
