WebSocket onClose/onError/onAbort is not being called
Hello,
I'm having weird situation: WebSocket connection is closed on page reload,
but none of my onClose/onError/onAbort handlers are being called
I have changed wicket version to latest SNAPSHOT and got some debug logs:
*ERROR* 05-01 16:10:21.740 o.a.w.p.w.j.WicketEndpoint:100
[EventExec-e2-t9] - An error occurred in web socket connection with id

with code '1006' and reason: Broken pipe
apache-tomcat-9.0.34 is being used as Web server
Standard WebSocketSettings is being used (notifyOnClose and notifyOnError
are ON)
Not sure if quickstart is possible here :(
Can it be fixed inside Wicket? Or shall I add some guards in my application?

we
check
whether the connection is still opened or it is a ClosedMessage.
ClosedMessage is broadcasted exactly for this reason:
https://github.com/apache/wicket/commit/ffa34c6bfbd2ccd8340e23ff1601edd3e0e941d6
We should simplify this condition to allow ErrorMessage too. Maybe even
AbortedMessage.
For the erroneous kind of messages we can even remove the connection from
the registry at the bottom of this method.
Please play with it and suggest a change!

Re: WebSocket onClose/onError/onAbort is not being called
Posted by Maxim Solodovnik <so...@gmail.com>.
Here are some more details on this issue
In our code I'm using IWebSocketConnection.sendMessage(String) method
The call is wrapped with try/catch to correctly handle any exception [1]
The problem is hard to reproduce due to IOException should happen exactly
at time of sendMessage do it's job
(in original report author hammer the page with F5 until error will occur)
As a result my try/catch doesn't play, I got "zombie" IWebSocketConnection
in IWebSocketConnectionRegistry
and incorrect application state due to I'm expecting to get disconnect
from onClose/onError/onAbort of my WebSocketBehavior
I see no other option than create periodic task to check for "zombies"
in IWebSocketConnectionRegistry
and restore application state
Are there any other options?

Re: WebSocket onClose/onError/onAbort is not being called
Posted by Maxim Solodovnik <so...@gmail.com>.
Hello Martin,
WicketEndpoint#onError is being called
"*ERROR* 05-01 16:10:21.740 o.a.w.p.w.j.WicketEndpoint:100
[EventExec-e2-t9] - An error occurred in web socket connection with id : 10"
The problem WebSocketBehavior#onError is not being called
So my application doesn't get notified the connection has been closed ....
:(

Re: WebSocket onClose/onError/onAbort is not being called
Posted by Martin Grigorov <mg...@apache.org>.
Hi Maxim,
If WicketEndpoint#onError() [1] is not called then probably there is a bug
in Tomcat.
I suggest you to post this question at Tomcat's users@.
