Hi Terry,
just did:
./testClusterServer.exe -w pipe0 &
./testDynamicClusterClient.exe pipe0
and it works fine how did you test it?
I followed the instructions in testDynamicClusterClient.cpp, which say
to also run testClusterClient. I thought that seemed a little
strange. Anyway, it works now. However, testDynamicClusterClient
dies with a "broken pipe" if I kill testClusterServer, so I might need
to modify testDynamicClusterClient a bit to make it behave the way I
want.
ups cut and paste error but that's quite obvious ;-)
You can use a try/catch block for detecting a killed server.
try
{
// redraw the server windows
_cluster_win->render((RenderAction *) _mgr->getAction());
}
catch(OSG_STDEXCEPTION_NAMESPACE::exception &e)
{
printf("error: '%s'\n", e.what());
}
Moving on... if I understand correctly, storeChangeList merges all
current changes into the _clStore and restoreChangeList pulls all
those changes back out all at once. Is that right?
yes
I tried to use this in my app as simply as possible. I set it up so
that every time changes are sent to my server, I do
mRemoteAspect->storeChangeList(OSG::Thread::getCurrentChangeList());
OSG::Thread::getCurrentChangeList()->clearAll();
which should keep an up to date store off all changes that I have
made. Then if my connection fails and I have to reconnect, I do this
mRemoteAspect->storeChangeList(OSG::Thread::getCurrentChangeList());
OSG::Thread::getCurrentChangeList()->clearAll();
mRemoteAspect->restoreChangeList(OSG::Thread::getCurrentChangeList());
mRemoteAspect->getStore().clear(); // tried with and without this
line, but I think it should be here. I get the same warnings with or
without it.
But after connecting and I try to send all these changes to my newly
started server, I get a long stream of warnings like these:
WARNING: Unknown TypeID: 726 for remote id 183
WARNING: Can't change unknown FC:202 skip 24 bytes.
So I'm pretty confused now. There's probably something simple that I
don't understand here, but I can't think of a simpler way to put this
in my app.
hmm difficult to say what's wrong just do exactly the same as in the
example.
What I was looking for originally was a way to artificially create a
complete change list from an existing model. I would think that would
be a simpler way to reestablish a broken connection because you
wouldn't have to keep a record of all changes since the start of the
client. Has this method been considered?
Yes I actually wanted the same but that's not so easy to implement so I
hacked this workaround.
Andreas
Internaly it keeps a changelist with all created objects, so before
clearing the cuurent changelist you save it via
RemoteAspect::storeChangeList(). And before connecting to the cluster
you restore the saved changelist via RemoteAspect::restoreChangeList()
into your current changelist.
Andreas
Thanks, but I'm still having some trouble understanding all this. Is
RemoteAspect::restoreChangeList() the call that is supposed to say
that everything in the graph is a new change. I'm afraid I haven't
gotten it to work in my code yet. And testDynamicClusterClient only
hangs when I run it on line 138:
_cluster_win->init();

Hi Terry,
there is an example in
OpenSG/Source/System/Cluster/Base/testDynamicClusterClient.cpp showing
how to dynamicly connect to the cluster servers without restarting the app.

I want to gracefully recover from network disconnections. Currently,
I am using RemoteAspect::sendSync() and ChangeList::clearAll() over
and over again to keep my server fed with scene graph updates.
But if my server gets disconnected and then reconnected I want to send
the entire graph over without having to rebuild the graph. I was
looking for something like ChangeList::setAll() to tell the server
that everything had changed, but I can't find anything like that. Is
there a simple way to just send over my whole scene graph?
