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	53d24f4e53	Speed up LOAD/SAVE mysql_servers #829 A further optimization in `MySQL_HostGroups_Manager::generate_mysql_servers_table()` makes `LOAD MYSQL SERVERS TO RUNTIME` around 35 times faster than original implementation. `SAVE MYSQL SERVERS TO MEMORY` is now over 10 times faster than the original implementation.	9 years ago
René Cannaò	ba7e37091b	Speed up LOAD MYSQL SERVERS TO RUNTIME #829 This commit is able to speed up LOAD MYSQL SERVERS TO RUNTIME up to 10x for very large mysql_servers table with tens of thousands of servers. Main improvements: * removed 1 unnecessary call to `generate_mysql_servers_table()` * replaced 1 call to `generate_mysql_servers_table()` with UPDATE statements when necessary * implemented new function `servers_add()` that replaces `server_add()` to perform bulk operation * replaced calls to `sqlite3_exec()` with proper parameters bindings * use of multirows INSERT statements (32 rows at the time) Miror improvements: * added new variable mysql-hostgroup_manager_verbose , 1 by default for backward compatibility and debugging * in not debug mode, access to HGM db has no shared cache * in not debug mode, tables in HGM have checks disabled Further note: * Once issue #797 is completed, `mysql_servers` in MyHGM can be simplified further	9 years ago
