*
|
|
* - 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)

|
Added a check for server status before routing the query. Now if the server is down it returns an error.
