no need to sync on slave if server is null ?!

Hi Maxim,

I found this fix from you:

Server s = clientSessionInfo.getServerId() != null ?
serverDao.get(clientSessionInfo.getServerId()) : null;
            if (s != null) {
                // no need to sync on slave if server is null
                clusterSlaveJob.syncMessageToClientOnSlave(s,
clientSessionInfo.getRcl().getPublicSID() , message);
            }

What should that mean and what enhancements should it bring?

Actually if server == null it means that the client is handled on the same
server.
Basically on a slave ALL sessions have the server == null, because from the
perspective of the slave every session is locally. In fact the slave does
not even know that he is a slave. He handles every connection as if there
is no difference.

So why should the slave NOT sync that message ? That makes no sense to me.

Server == null is a correct implementation and it should not throw any
NullPointerException.
It simply means that the Session is local and not on another server.
Actually only this kind of session could have a s != null:
A session that is synced from the slave to the master. The master would
have this session with a Server != null.

So your comment does not makes sense to me.
Of course slaves do sync messages. On the slave the "server" argument is
_always_ null. But of course the slave should still sync that message.

Re: no need to sync on slave if server is null ?!

Posted by "seba.wagner@gmail.com" <se...@gmail.com>.

Hi Maxim,

thanks I also fixed the other exception when the server is null.
There was actually just missing a return statement. In case the RoomClient
is already found locally, by:
this.clientListManager
                                .getClientByPublicSID(publicSID, false,
null);
then you simply sync the message to this client locally, no need to look it
up in the cache if there is a RoomClient session open on any other server.
So there was simply a "return" missing to exit the method in that if-clause.
I have added another Exception now when the "server == null" case happens
again (but actually it should not).

Thanks!
Sebastian

Re: no need to sync on slave if server is null ?!

Posted by "seba.wagner@gmail.com" <se...@gmail.com>.

Thanks,

let me try to debug that. I think the root of the issue is somewhere else.

Re: no need to sync on slave if server is null ?!

Posted by Maxim Solodovnik <so...@gmail.com>.

the steps are very simple:

0) no servers are configured
1) select system restore in SWF admin
2) select backup
3) click "upload"
Result: Server is NULL, NPE without a fix (seems it affects nothing)

Hello Sebastian,

I catch NPE while debugging :(
Clean just imported DB was used. The NPE was 100% reproducible on my server

I'll doublecheck

Re: no need to sync on slave if server is null ?!

Posted by "seba.wagner@gmail.com" <se...@gmail.com>.

In fact by reading this method, logically your if-statement should never be
true.

Cause:
the method "sendUploadCompletMessageByPublicSID" first tries to get the
RoomClient with:
RoomClient currentClient = this.clientListManager
                                .getClientByPublicSID(publicSID, false,
null);

The null at the end means it searches a RoomClient with that publicSID and
the serverId = null. That means it searches for a Connection/Session
LOCALLY.

If RoomClient is != null => Then it can directly use the regular sync
methods. Cause it means that the session is handled on the same server.
If tRoomClient is NULL, then it means it is handled on a slave server.
I have impelemented this so that the master can sync the upload complete
message to the slave.

What you have implemented then at the end with that if-clause, actually the
implementation logically can never run into that.
If the serverId == null, the RoomClient would have already be found by the
first getClientByPublicSID(publicSID, false, null);

>From my point of view an Exception should here be thrown and we should find
out how and when it could happen that the "server" argument is null here.
Cause actually it would mean a much bigger issue.

Where did you find any kind of issue that makes you think that this
if-clause is needed?

Sebastian
