|
|
* - Maxscale.cnf with "filters=QLA|testfilter" for RWSplit router service, 'testfilter' is not defined.

I mistyped a module name (for a filter in this case)
|
|
|
|
[testfilter]
|
|
type=filter
|
|
module=foobar
|
|
|
|
There were no warnings about this on startup at all, but at the first time trying to connect to a service this filter was used in maxscale crashed with a segmentation fault after writing the following error log entries:
|
|
|
|
2014 09/08 15:00:53 Error : Unable to find library for module: foobar.
|
|
2014 09/08 15:00:53 Failed to create filter 'testfilter' for service 'testrouter'.
|
|
2014 09/08 15:00:53 Error : Failed to create Read Connection Router session.
|
|
2014 09/08 15:00:53 Error : Invalid authentication message from backend. Error : 28000, Msg : Access denied for user 'maxuser'@'localhost' (using password: YES)
|
|
2014 09/08 15:00:53 Error : Backend server didn't accept authentication for user denied for user 'maxuser'@'localhost' (using password: YES).
|
|
|
|
Two problems here:
|
|
|
|
1) can't check up front that my configuration is valid / without errors without connecting to each defined service
|
|
|
|
2) maxscale crashes instead of handling this situation gracefully (e.g. ignoring the misconfigured filter, or disabling the service that refers to it alltogether)
