Re: [incquery-dev] Xtext 2.4 compatibility branch created
|
I also faced memory issues, but this is not only related to the incquery
workflow. With the new xtext version several other languages needed more
memory during workflow execution for me.
Hi,
is this still thrown by the workflow (if I understand the trace correctly, it is)? If yes, then could you try to add some memory to the workflow execution (-Xmx, -XX:MaxPermSize)?
Now that you mention, I also had memory issues, but simply adding more memory solved it (in my case I have added -Xmx512m to the Run configuration).

Hi,
I will check it tomorrow - there should be no such error message during generation, but maybe I missed it during generation and introduced some issue in the grammar.

Hi,
after quite a lot of work (thanks for the help to Gábor and István), I created the first working version of EMF-IncQuery that uses Xtext 2.4.
Because of the required stability for other projects (and as I am not 100% sure that all bugs are ironed out), I have only put it to a new branch on git, and would wait till Monday to merge it for real.
If someone would be kind to test it, he should install Xtext 2.4 (e.g. from the Kepler update site or the Xtext release site), check out the xtext-2.4 branch from git, and test it out. It is normal, that all IncQuery projects are to be cleaned and rebuilt, as there are some changes internally in the EMF metamodel, so the generated code does not work out of the box.
If some issue is found, please write a comment for https://bugs.eclipse.org/bugs/show_bug.cgi?id=398809
Thanks,
