CustomLogin + HRC + isForceLogout

[Fraggle]

Hi,

I'm trying to handle nicely the various connexion events that may happen in my game.

From what I understand, here are the important bits:

• isForceLogout set to true in the zone config will force an existing logged in user with the same username to be disconnected if a new connexion from the same username is attempted.

• userReconnectionSeconds controls the amount of seconds that a socket will remain opened if there is a network issue between the client and the server, allowing the smartfox client lib to reconnect gracefully.


Here are the various scenarios I think might happen:

• A: User log in with a client, then log in with another client while the first one is still there.

• B: User log in with a client, a network error happen but it come back quick enough.

• C: user log in with a client, the network is disconnect long enough, the connection cannot not be re-established.


In scenari A:

With isForceLogout true and userReconnectionSeconds : 0, the first client is disconnected, the second client is connected but the login does not complete, here is a log from the server:

I did not try scenario B and C as A is already puzzling me.
I dont understand what I am doing wrong... can someone help me?

Thanks,

Hi.

Are you using SFS2x RC3?
And can you please give some more details about what procedure you're using to test this?
I created a simple client that connects and logs in with an username, launched 2 of these clients and the 1st one was successfully kicked when the 2nd one logged in, with no errors on the server side.

Hi!

Yes, I'm using RC3. As the title said, I'm using customLogin as well....
Basically:

Client connect with oauth key/secret, smartfox does an http call to our rest api (using oauth), get the user details, fill in the username (using out data) and that's it.

Hi Fraggle,
I have tested your case A by adding a custom login extension to a test Zone.

ReconnectionTime == 0:
I am not able to reproduce/detect any errors, the old user gets properly disconnected first and the new one enters without problems. There might be something going on in your extension?

ReconnectionTime == 6:
I do see the same error, but it's not a problem, in fact you can ignore the issue and you should have noticed that the user does login.

The idea here is that the Reconnection system sees user LAPO disconnect and then LAPO opens a new socket and attempts a new connection.
HRC checks the sessionId and it doesn't match with the previous session, hence the message.

In theory the forceLogout feature should not be used with the HRC turned on for the reason I just explained, so you might want to turn it off. Otherwise if you decide to keep it active you will get the message but the system will work correctly, so no big deal.

Hope it helps

I'm having the same issue and errors as in scenario A, in that the first user is disconnected correctly but the server throws this error

Code: Select all

::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
Exception: com.smartfoxserver.v2.exceptions.SFSRuntimeException
Message: java.nio.channels.ClosedChannelException
Description: Error during event handling: com.smartfoxserver.v2.exceptions.SFSRuntimeException: java.nio.channels.ClosedChannelException, Listener: { Ext: battleMonkeys, Type: JAVA, Lev: ZONE, { Zone: BattleMonkeys }, {} }

com.smartfoxserver.v2.entities.SFSZone.applyForceLogin(SFSZone.java:1453)
...

and the second user is left in limbo as his login doesn't seem to complete.

I do have custom login extension but both cases seems to proceed correctly through it, I'm not sure what I could be doing in there that is causing this?

Thanks

Did you read my previous reply? The answer is valid for you too.
