* @file bug658.cpp regression case for bug 658 ("readconnroute: client is not closed if backend fails")
|
|
*
|
|
* - Connect all MaxScale
|
|
* - block Mariadb server on Master node by Firewall
|
|
* - execute query
|
|
* - unblock Mariadb server
|
|
* - do same test, but block all backend nodes
|
|
* - check if Maxscale is alive

|
|
* Reproduce:
|
|
* 1. connect readconnroute with mysql client
|
|
* 2. fail the backend server
|
|
* 3. execute query by using mysql client
|
|
*
|
|
* >> client hangs if write to backend socket doesn't return error (which doesn't happen in many cases)
|
|
* Comment 1 Markus Mäkelä 2014-12-23 09:19:17 UTC
|
|
* Added a check for server status before routing the query. Now if the server is down it returns an error.
