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	7b3757a273	Remember if the current connection has an unknown transaction status ... The fix for bug #1038 was to not return a connection to the connection pool if it has an error. Although this is correct, it also has the side effect that connections coming from connection pool and failing during the first query because the connection was already broken, would be considered as possibly to run a transaction. That is incorrect. Now at connection level it is tracked if the transaction status is known or not.	8 years ago

René Cannaò	f0a2edce4a	Drafting tracking of GTID	8 years ago
René Cannaò	7ab67dc685	Bug fix for #1333 ... Prepared statements counters are now computed at runtime instead of on-demand. Now MySQL_STMT_Manager_v14::get_metrics() doesn't depend anymore from the number of prepared stataments cached. The old code (slow code) is still present in the DEBUG version, and used to validate the new counters. That also means that DEBUG versions are way slower than non debug versions.	8 years ago

René Cannaò	7eccd347e3	Add support for Percona Heartbeat #1248 ... This commits adds a new variable: mysql-monitor_replication_lag_use_percona_heartbeat This variable defines the percona heartbeat table used to check replication lag. If set, replication lag is checked against the defined table, otherwise `SHOW SLAVE STATUS` is used.

René Cannaò	7dbcbc3e7a	Bug fix for #1188 ... * all commands expected in Admin are serialized * Cluster get mysql servers information directly from MyHGM * Before applying MySQL servers changes, Cluster fetch again the checksum to verify it didn't change	9 years ago
René Cannaò	18f6826ef7	Added new variable to limit the number of backend connections per second ... Variable name is `mysql-throttle_connections_per_sec_to_hostgroup` . Curently it is a global variable and limits the number of new connections per hostgroup, and not per specific node. For example, if mysql-throttle_connections_per_sec_to_hostgroup=100, no more than 100 new connections can be created on any hostgroup no matter the number of servers in that hostgroup. The default is very high (1000000) thus not changing default behaviour. Tuning this variable allows to control and throttle connections spikes to the backend servers. Added also new status variable `Server_Connections_delayed`. This is a counter of how many times Hostgroup Manager didn't return a connection because the limit was reached. It is worth to note that a single client request could make multiple requests, therefore this variable counts the number of time a new connection wasn't created and not how many requests were delayed.	9 years ago

René Cannaò	b211e9903f	Merge branch 'v1.4.2-checksum' into v1.4.2	9 years ago
René Cannaò	e3c4cb9964	A lot of changes all related to Cluster ... In `MySQL_Cluster` class added functions to sync with remote node, like: - `pull_mysql_query_rules_from_peer()` - `pull_mysql_servers_from_peer()` - `pull_mysql_users_from_peer()` - `pull_proxysql_servers_from_peer()` Added 8 new global variables in Admin. 4 variables determine after how many different checks the remote configuration will be synced: - cluster_mysql_query_rules_diffs_before_sync - cluster_mysql_servers_diffs_before_sync - cluster_mysql_users_diffs_before_sync - cluster_proxysql_servers_diffs_before_sync 4 variables determine if after a remote sync the changes need to be written to disk: - cluster_mysql_query_rules_save_to_disk - cluster_mysql_servers_save_to_disk - cluster_mysql_users_save_to_disk - cluster_proxysql_servers_save_to_disk Table `proxysql_servers` is now automatically loaded from disk to memory and into runtime at startup. Added new Admin's command `LOAD PROXYSQL SERVERS FROM CONFIG` to load `proxysql_servers` from config file to memory (not runtime). Internal structures with credentials in MySQL_Authentication moved from `unsorted_map` to `map` : this to ensure the right order when generating the checksum. Config file supports both `address` and `hostname` for `mysql_servers` and `proxysql_servers` , #1091 `ProxySQL_Admin::load_proxysql_servers_to_runtime()` now has a lock or no lock option, to avoid deadlock For now, Cluster module is quite verbose.	9 years ago

René Cannaò	ee8110a515	Enhancement on Cluster solution ... This commit introduces: 2 new tables: * `runtime_checksums_values` : stores checksums of configurations in runtime.

TO RUNTIME` * `admin-checksum_mysql_query_rules` * `admin-checksum_mysql_servers` * `admin-checksum_mysql_users` ProxySQL Cluster connections now have timeouts: * 1 second timeout for CONNECT and WRITE * 60 seconds timeout for READ (useful for long poll)	9 years ago

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	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	10 years ago
