a68d83ff7f Moved error messages about broken pipe to DEBUG build since in cases we've seen it is due to socket closing in same host. Other case is that MaxScale attempts to write COM_QUIT (ending message) to socket that other thread already closed. 
Added counter clean-up code to readwritesplit closeSession. If operation counters have leaked, that is, due to some error in query routing some counter have been left positive, it is zeroed at session ending. This ensures that there is no garbage in global counter even if individual session wouldn't clean up its counters.

e944ae2e70 http://bugs.skysql.com/show_bug.cgi?id=453 
Fixed bug in session command resul handling. In case where backend sent error message the session command cursor wasn't updated properly.

Added check to bref_clear_state, if bref's waiter counter would go negative, decrement to global operation counter is skipped.

5c2333430d Removed configuration consistency checks, since monitor's configuration can't be easily read when router instance is created.

b875936a21 MAX-94, Added configuration parameter, max_slave_replication_lag=<longest allowed replication lag in seconds> to router section. 
Parameter can be changed runtime but it requires reloading of config.

6d672cb967 Added status bit BREF_QUERY_ACTIVE to indicate if a query, other than session command, sent to backend for execution. The flag is cleared when the first packet belonging to the response arrives. 
The flag is part of the active operation counting, which is utilized in load balancing. The active operation count per backend is used by default as criteria when router chooses to which backend a query should be routed.

862d504a74 Enabled set and clear the flag BREF_WAITING_RESULT. It is actually a counter which is modified with atomic operations only. Setting and clearing BREF_WAITING_RESULT also includes atomic increment and decrement of corresponding backend server's current operations counter, backend_server->stats.n_current_ops. 2014-06-30 11:00:04 +03:00

fcf67716fd Added mechanism for choosing slave for a query based on the current load in all connected slaves. Counting operations is not correctly done here. Reading values and choosing accordingly is done. 
Fixed several things in session command reply processing.
