[Spacewalk-list] Empty "Overview" page after upgrading from 2.7 to 2.8

Tue Apr 24 09:14:37 UTC 2018

Hello,

Our instance is running Scientific Linux 7.4 , PostgreSQL 9.2 local

root at spacewalk ~ # rpm -qa | grep spacewalk-java
spacewalk-java-config-2.8.78-1.el7.centos.noarch
spacewalk-java-lib-2.8.78-1.el7.centos.noarch
spacewalk-java-2.8.78-1.el7.centos.noarch
spacewalk-java-postgresql-2.8.78-1.el7.centos.noarch
root at spacewalk ~ # rpm -qa | grep dwr
dwr-3.0.2-1.el7.centos.noarch

The upgrade was done yesterday afternoon, exactly according to the documentation.
With spacewalk 2.7 we used dwr-3.0rc2-8.el7.noarch , I can't find the dwr-3.0rc2-9 in the old yum logs anywhere so it was never installed on this system.

I'm only seeing one error in the catalina log, related to the AJP connector :

Other than that the catalina.out log is clear.

Subject: Re: [Spacewalk-list] Empty "Overview" page after upgrading from 2.7 to 2.8

Hello,

could you please provide information on which system you have tried? I've just tested the scenario on different systems and didn't bump at the issue - I can see Overview page after upgrade. However, the behavior you described is the same as having spacewalk-java-2.8 and dwr-3.0rc2-9. This combination causes blank main page (BUT traceback in catalina.out as well) but it should not happen as there's a dependency on it. So far it really looks as some sort of caching issue.

Thank you for your info

Jiri

Hi all,
after upgrading my Spacewalk server from 2.7 to 2.8 I'm experiencing a weird bug: the "Overview" page that Spacewalk shows after the login is empty. I can see the page header and the left-side menu but It doesn't display all the nice summaries of the Spacewalk infra.

The weird thing is that nothing strange appears on the log files (both catalina.out and rhn_server_xmlrpc.log). No stacktraces, no errors at all.

Maybe I'm wrong but I suppose that something got broken in this commit:
https://github.com/spacewalkproject/spacewalk/commit/ace6add83252e33c776e5803947fff9ef361885a

For now, my workaround was to downgrade the drw package from the 3.0.2-1 to the 3.0rc2-9 version. I also needed to downgrade the spacewalk-java package to spacewalk-java-2.8.73-1 since it's a tightly-coupled dependency of dwr.

After the downgrade, I'm able to see the "Overview" page again.
I've also tried to clean the tomcat cache and restart my spacewalk setup but the issue was still present.

Thanks for your help.
Angelo Lisco
