Re: [ptp-dev] Hang in RemoteServicesProxy.getConnectionManager
|
Greg
I'm using the preferences dialog I get by going to
preferences->PTP->Service Configurations then adding service
configurations there
This seems to work better after updating to the latest PTP, although any
launch service (PE proxy) I add doesn't seem to get added to the service
configuration. If I add the PE proxy to the service configuration thru the
dialogs invoked from the resource managers view, then the launch service
gets added to the service configuration. I'm not sure if this is a problem
or I'm going thru a wrong sequence in adding launch services.
The hang seems to be a timing/race condition at plugin startup. My plugin
has registered a listener for IServiceModelEvents. I register it for
IServiceModelEvent.SERVICE_CONFIGURATION_CHANGED and
IServiceModelEvent.SERVICE_CONFIGURATION_SELECTED events. My listener is
pasted below. I can see where it gets
IServiceModelEvent.SERVICE_CONFIGURATION_CHANGED events pretty early in
Eclipse startup, and I never get an Eclipse main window.
If I only handle IServiceModelEvent.SERVICE_CONFIGURATION_SELECTED
events, I don't get a hang.
private void setServiceAttributes() {
IResourceManager resourceManagers[];
IResourceManager resourceManager;
String remoteServiceID;
IPUniverse universe;
IServiceProvider launchServiceProvider;
IServiceProvider newToolServiceProvider;
IRemoteConnection newRemoteConnection;
IRemoteServices newRemoteServices;
IRemoteFileManager newFileManager;
newToolServiceProvider = newServiceConfiguration
.getServiceProvider(hpctService);
if (newToolServiceProvider == null) {
MessageDialog
.openError(null, Messages.
PTPRemoteOperations_0,
"Performance
analysis service not defined in active service configuration");
return;
}
launchServiceProvider = newServiceConfiguration
.getServiceProvider(launchService);
if (launchServiceProvider == null) {
MessageDialog
.openError(null, Messages.
PTPRemoteOperations_0,
"Launch service
provider not defined in active service configuration");
return;

if (newFileManager == null) {

PTPRemoteOperations_0,

return;
}
// Update to new attributes for newly selected service

Dave,
Please update everything as I've made a large number of changes in the
last couple of days.
Service configurations should be saved when the services core plugin is
stopped. This should happen when Eclipse is shut down, but it may be
unreliable. If you kill the Eclipse session then it definitely won't be
saved. I plan to change this to save whenever a configuration is changed
which should make it more robust.
Which preferences dialog are you using to edit the service configuration?
These are still in a bit of transition at the moment.
What sort of RSE connection are you using? Is RSE running before you see
the hang (i.e can you browse files in the Remote Systems view?

I updated to the current PTP head this morning and I am now running into a
hang on a call to RemoteServicesProxy.getConnectionManager().
I started an Eclipse runtime instance using the debugger and suspended the
main thread. I consistently get the traceback in the attached screen
capture. It looks like RSE is waiting for an operation to complete.
The remote service I see displayed in the preceding println call is
'Remote service is
org.eclipse.ptp.remote.internal.core.RemoteServicesProxy@d0c3d5'
The method in my code where the hang happens is the following, where I
have set up currentServiceConfiguration when my code gets an
IServiceConfiguration event notification. It also seems that service
configurations, resource managers and services within a service
configuration are not always being saved in persistent storage, since if I
shut down and restart the runtime Eclipse instance these objects aren't
always restored. Finally, it seems that if I use the service configuration
preferences dialog to edit a service configuration, and there is a launch
service defined, then when I add a performance analysis service, the
launch service seems to disappear. Could this be related to the hang?
Any other ideas?
