Description Eike Stepper

2012-09-06 13:22:31 EDT

For some time now my builds have recurring but not permanent problems when they (Buckminster) accesses (resolves or materializes) external dependencies:

https://hudson.eclipse.org/hudson/job/emf-cdo-maintenance/
https://hudson.eclipse.org/hudson/job/emf-cdo-integration/

It seems to fail randomly and I have no clue why. 
Maybe "just" an instable route?

Does this problem get any attention?

More failures:

I can't fix sourceforge  :/

http://net4j.sourceforge.net/update/content.xml

Hmm, the last time I tried some of the URLs in question they all worked for me locally but not from Hudson. Now you seem to be right, though. I'll close this bug and watch sourceforge...

When I tried the URL from my browser, it seemed to work.  I wonder if sourceforge isn't filtering based on the Java user agent.

Comment 6 Eike Stepper

Darned! You confused me with the URL you gave in comment #3.

The p2 repo has a content.jar, not an XML. And I can download that with my local browser. http://net4j.sourceforge.net/update also works.

That makes me think again that there's a sporadic problem on/from the Hudson server. Reopening.

If I look at my proxy logs, I see hundreds of these errors:
[Fri Sep 28 04:12:00 2012] [error] [client 172.x.x.x] (104)Connection reset by peer: proxy: error reading status line from remote server net4j.sourceforge.net
[Fri Sep 28 04:12:00 2012] [error] [client 172.x.x.x] proxy: Error reading from remote server returned by http://net4j.sourceforge.net/update/p2.index


net4j.sourceforge.net is the only site in my error logs.  You'll have to either mirror that dependency locally or fetch it from somewhere else.

Maybe sourceforge got tired or concerned about so many failed requests for "p2.index" it assumes there's something wrong with that client request :/

Comment 9 Eike Stepper

2012-09-28 10:20:28 EDT

Hmm, may be. I'll try to move that stuff to GitHub and build it with something like travis. Then I'll also add p2.index files and try how that works. Thank you for the hints!

Just a random data point: I got a 500 from Sourceforge while trying to grab the Vine VNC server for the new Mac slave yesterday.  Maybe with the myPHPAdmin mirror hack they're doing a review?
