Javier Jaramago Fernández	abccb39201	Add new variable 'mysql-query_rules_fast_routing_algorithm' ... - Implemented new variable 'query_rules_fast_routing_algorithm' that allows choosing between the classic per-thread hashmaps for 'query_rules_fast_routing' searches (1), and a new unique global hashmap (2). - Improved locking time on 'QueryProcessor::rwlock' during 'load_mysql_query_rules_to_runtime'. - Changed computation of 'mysql_query_rules_memory' to be lazily updated by threads themselves while building the per-threads maps. - Fixed 'ProxySQL_Admin::stats___memory_metrics' report of the memory metrics. - Improved 'PROXYSQLTEST 17' command, for being able to micro-benchmark and check 'query_rules_fast_routing_algorithm'.	3 years ago

René Cannaò	51df157f3b	Rename query_cache_soft_ttl_percentage to query_cache_soft_ttl_pct	3 years ago
Javier Sánchez Parra	f5281b236b	Add soft TTL to Query Cache entries ... When Query Cache entries reach the soft ttl, the next query hit the backend and refresh the entry. While the refresh happens, other queries keeps getting the "old" Query Cache entry. Soft ttl is a percentage of the cache ttl and is defined by a global variable for all the entries. If the value is 0, soft ttl is disabled and no used.	3 years ago

René Cannaò	4bfe3e5878	Added mysql-monitor_replication_lag_group_by_host ... If variable mysql-monitor_replication_lag_group_by_host=false: (default) Monitor will perform 1 replication lag check per server per hostgroup. If variable mysql-monitor_replication_lag_group_by_host=true: Monitor will perform 1 replication lag check per server. This variable need to be set only in setups in which the same server is configured in many hostgroups, thus reducing the number of checks	4 years ago

René Cannaò	fdff65daea	Implementation of max_transaction_idle_time ... Former max_transaction_time is now renamed to max_transaction_idle_time. mysql-max_transaction_idle_time defines the maximum time a transaction can stay idle. mysql-max_transaction_time defines the maximum time of a transaction since its start.	6 years ago
René Cannaò	b8161c7fc4	Allow compile on FreeBSD	6 years ago
René Cannaò	507a68db29	Variable mysql-monitor_replication_lag_count ... Renamed variable mysql-monitor_replication_lag_retries to mysql-monitor_replication_lag_count to match other variables naming convention. As it is a counter, it minimum value is changed to 1. Maximum value sets to 10. Use of thread storage variable mysql_thread___monitor_replication_lag_count instead of GloMTH->variables.monitor_replication_lag_retries to avoid dirty reads .	6 years ago

René Cannaò	848ddb2177	Added variable mysql-connect_timeout_client ... This also fix bug #1132	6 years ago
René Cannaò	33d8db02a6	Change the mapping logic for SESSION_TRACK_GTIDS ... Changing the mapping logic in SESSION_TRACK_GTIDS in frontend and backend connections. Up to now, frontend and backend `SESSION_TRACK_GTIDSs match. This is now changed: * backend connections are by default set to `mysql-default_session_track_gtids` * if `mysql-default_session_track_gtids=OFF` (the default) , `session_track_gtids` is not changed on backend * if the client asks for `session_track_gtids=OFF` , proxysql ignores it (it just acknowledge it) * if the client asks for `session_track_gtids=OWN_GTID` , proxysql will apply it * if the client asks for `session_track_gtids=ALL_GTIDS` , proxysql will switch to OWN_GTID and generate a warning * if the backend doesn't support `session_track_gtids` (for example in MySQL 5.5 and MySQL 5.6), proxysql won't apply it. It knows checking server capabilities This commit also deprecates function `MySQL_Session::handler_again___verify_backend__generic_variable()` ProxySQL is now also able to know when proxysql binlog reader is perhaps in use tracking all gtid_port in mysql_servers. This feature in future will be used to deprecate `mysql-default_session_track_gtids`	6 years ago
René Cannaò	4748c7d052	Various bug fixes related to deprecated mysql-default_ variables ... Extended `mysql_variable_st` to add a new variable `is_global_variable`. Using this variable we define the global variables. Modified `mysql_tracked_variables[]` to also specify `is_global_variable`. Removed `default_charset` from `MySQL_Threads_Handler::variables` to use `mysql_tracked_variables[]` instead. Removed `default_charset` also from `mysql_thread_variables_names[]`. Fixed `MySQL_Threads_Handler::get_variable_string()` : it was *not* returning `mysql-default_` variables. `MySQL_Threads_Handler::set_variable()` adds `mysql-default_` variables only if `is_global_variable` is set. In `MySQL_Threads_Handler::set_variable()` replaced a `strcasecmp()` with `strcmp()` for `mysql-default_` variables. `MySQL_Threads_Handler::get_variables_list()` returns only `mysql-default_` variables with `is_global_variable` enabled. `MySQL_Threads_Handler::has_variable()` for `mysql-default_` variables returns true only if variable has `is_global_variable` enabled. `MySQL_Thread::refresh_variables()` does not refresh `mysql-default_` variables if `is_global_variable` is not enabled. `MySQL_Thread::MySQL_Thread()` initializes to NULL all `mysql_thread___default_variables[]` variables. Completely disabled in `ProxySQL_Admin::flush_mysql_variables___database_to_runtime()` the logic applied to all charset variables. In the same methos was implemented the logic described in #1785 : `mysql-default_charset` and `mysql-default_collation_connection` must be compatible: * if only one is present, the other is configured automatically * if not compatible, `mysql-default_charset` is configured from `mysql-default_collation_connection`	6 years ago

René Cannaò	c28deb7c7d	Generalize the use of session variables ... Added new array mysql_tracked_variables[] that defines the tracked variables. Ideally, tracking a new session variable will requires adding only a couple of lines of code. Removed session variables from mysql_thread_variables_names: - now both MySQL_Threads_Handler::get_variables_list() and MySQL_Threads_Handler::has_variable() rely on mysql_tracked_variables[] Simplified MySQL_Variables, as it now also uses mysql_tracked_variables[] . Simplify parser in MySQL_Session Generalized code to handle two variables together: - sql_auto_is_null - sql_safe_updates Migrating more session variables to new algorithm - collation_connection - net_write_timeout - max_join_size Migrating more session variables to new algorithm - collation_connection - net_write_timeout - max_join_size	6 years ago

René Cannaò	e9dc7a9b60	Implementation of SQLI fingerprints whitelist ... libsqlinjection generates a lot of false positives. This commit introduces a new table: mysql_firewall_whitelist_sqli_fingerprints This table can list fingerprints generated by libsqlinjection: if the fingerprint is listed in this table, proxysql will consider it as a false positive.

René Cannaò	485d313514	Further development of firewall whitelist. ... * introduced 2 new variables: - mysql-firewall_whitelist_enabled : defines if the firewall with whitelist algorithm is enabled or not - firewall_whitelist_errormsg : error message returned to the client if an error message is not already set * Query_Processor returns firewall_whitelist_mode to the calling MySQL_Session, but the logging on error log currently happens within the Query_Processor itself * if mysql-firewall_whitelist_enabled is turned on and a user it is not found in mysql_firewall_whitelist_users , the default behavior is that query is rejected * lookup on mysql_firewall_whitelist_users happens for username@ip (specific IP) and username@'' (all IPs) . Match on network subnet is currently not implemented * implemented SAVE MYSQL FIREWALL FROM RUNTIME * fixed implementation of SAVE MYSQL FIREWALL TO DISK * runtime configuration can be viewed in runtime_mysql_firewall_whitelist_rules and runtime_mysql_firewall_whitelist_users	6 years ago
