mysql_common.c:gw_MySQL_get_next_packet didn't handle case where an insert command followed by alter table in the same read buffer. It shouldn't been possible without multi-statement being set.

mysql_common.c:mysql_protocol_done: added protocol state check. Used not to check it which caused double free of allocated memory.

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.

Improvements to CLI commands and client
2014-06-16 07:57:12 +01:00
5bcae64538
When protocol closes DCB it calls dcb_close instead of dcb->func.close. dcb_close then calls dcb->func.close. This is now changed to all protocols and routers.
...
Rwsplit handles ERRACT_NEW_CONNECTION by clearing backend reference, removing callbacks and associating backend reference with new backend server. If it succeeds and the router session can continue, handleError returns true. Otherwise false. When ever false is returned it means that session must be closed.
Rwsplit now tolerates backend failures in a way that it searches new backends when monitor, backend, or client operation fails due to backend failure.

Whenever monitored server's state changes, a callback, router_handle_state_switch is called for each DCB in MaxScale session. The DCB referring to the server in question will be passed as parameter to backend DCB's hangup function.
...
The logic that solves the situation is not in place yet.
2014-06-13 13:30:50 +03:00

Added callback for rwsplit router which traverses through every rwsplit router session and for each rses, all backend references. Each bref is checked whether it is connected to non responsive server and if it is flagged to be waiting for response from the non-responsive backend. For matching ones, backend protocol's hangup function is called.
