Hi,

I am encountering some problems of Java Heap Space during building workspace (then Xtext building I suppose) given the fact I have 1500 sources in my project.
Changing Eclipse memory settings does not change anything.

I am running Xtext 1.0.1.v201008100627 and Eclipse Helios.

I saw there is already something similar to my problem https://bugs.eclipse.org/bugs/show_bug.cgi?id=307665. But I am not sure fix is already available...

Thanks,
Alexandre

Hi Alexandre,

the ticket was closed today. Documentation on how to use the clustered
builder will follow. Expect it to be available in Xtext 1.0.1

Sebastian

Hi Sebastian,

That is great news!

Actually I updated Xtext with the latest nightly build. I was wondering if you could give me a quick hint on how to use this new functionality.

Thanks
Regards,
Alexandre

I guess this would be a good candidate for a generator fragment ;-)

Hi,

I followed the blog entry but I am now encountering another problem reproductible on different platforms. Actually, the building project job blocks at resource 21, 25 or 1421 for 1466 resources.

Do you have any idea about this problem?

Thanks,
Regards,
Alexandre

Hi Alexandre,

do you mean the job is stuck and will never complete or does it just
take some time to finish the resource?
I'ld assume you are refering the the task "updating resource
description" during the build process? A long delay may be caused by
strong dependencies on many other resources which have to be loaded to
establish cross references for a certain resource. This may take some time.

If you feel that the build process is too slow or you have other
scalability issues, I'ld recommend to perform an in-depth analysis /
profiling for your particular language. Please don't hesitate to contact
us (see footer) if you need any project specific help that goes beyond
the support in this newsgroup.

Regards,
Sebastian

Hi Sebastian,

Indeed the job is stuck. Letting it continue for several hours does not change anything and stopping it does not work which means that you need to restart eclipse.

The problem is still there even I have something like that for my scope provider :

@Override
public IScope getScope(EObject context, EReference reference) {
   return IScope.NULLSCOPE;
}

To add to what you mentioned about long delays and strong dependencies, I am now wondering how the xtext building really works. My problem occurs during "loading affected resource 25 of 1466". What does xtext really do when loading a resource? Do I have to build some "core" resources before the others as my language is dynamic (dependencies resolved at runtime : no "import" key)?

Regards,
Alexandre

Hi Alexandre,

it does what it tells. Loading resources just calls getResource for each
available uri. Can you create a thread dump when the builder is stuck?
I'ld assume that it loops endlessly although I've no idea why or where
this may happen.

Sebastian

Hi Sebastian,

I went further on the debugging and found the file causing the problem. It seems that indeed this specific resource can not be loaded (see loadResourceCluster#ClusteringUpdater and getResource(uri) calling).

Moreover, I am not able to open this file in my language editor (in text editor view it is fine). It is looping endlessly during the initialization of the corresponding XtextEditor. Do you have any idea that may cause the problem ?

Thank you very much,
Regards,
Alexandre

Hi Alexandre,

please provide a stacktrace from the never ending loop. It may be copied
from the debug view (just pause the vm when the editor is stuck).

Sebastian

I've encountered another problem:

I'm using the last nightly (since clustering is not in 1.0.1RC1).

I get this Message:

!MESSAGE Platform filter did not match: (& (osgi.os=linux) (osgi.arch=x86))
0 [main] ERROR org.eclipse.xtext.ui.shared.internal.Activator - org.eclipse.core.runtime.CoreException: Plug-in de.stelzer.sntsworkbench.ui was unable to load class org.eclipse.xtext.builder.clusterin.ClusteringModule.

I'm on Windows 7 x64 here...

Hi Johannes,

do you face the same problem with Xtext 1.0.1 which was released last
Wednesday? Do you get any other errors in the log? Which platform do you
use?

Sebastian

Hi Sebastian,

it was my fault - as you can see I mispelled the full qualified classname!
