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. To be set, the value should match the following regex: ``` `?([a-z\d_]+)`?\.`?([a-z\d_]+)`? ```	8 years ago
René Cannaò	6fc08b3f3d	Added variable mysql-verbose_query_error #1059 #1060 ... If variable mysql-verbose_query_error is set, "Error during query" message will be extended adding: - username - client IP - schemaname - digest of the original query (not the original query itself)	9 years ago
René Cannaò	2dce7013df	Added variable autocommit_false_is_transaction #1256 ... If autocommit_false_is_transaction=true (false by default), a connection with autocommit=0 is treated as a transaction. If forward_autocommit=true (false by default), the same behavior applies.	9 years ago

René Cannaò	44cc349a09	Merge branch 'v1.4.1-1034' into v1.4.4-bandwidth	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

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
