Re: [cross-project-issues-dev] Strange Hudson test failures


Correction: EMF's one change is a major rewrite of the URI class.
raised concerning thread safety.

The change was authored on 5-Mar and committed on 12-Mar.

Is it possible that the evolving Tycho platform builds distributed the change on 8-Mar and retracted it on 9-Mar?

Hi David

Is there anything more that you can share with us?

Currently my three projects OCL, QVTd and QVTo are all showing unexpected test failures. These are not the usual early collapses attributable to a bad Hudson day. So my suspicions point to EMF or platform. EMF has only had one change against which I've raised a critical regression (Bug 403289), but that does not correlate well with the actual test failure pattern. I would only expect Bug 403289 to give build failures if a 1.5 JRE is present, which it isn't on our Hudson jobs.

On 8-Mar I spent a long time trying to reproduce QVTo test failures that appeared after I removed the org.junit4 dependency. I was unsuccessful and when I continued on 9-Mar the problems had vanished. Perhaps it was Hudson, perhaps it was the platform that went through a significant change.

Looking at the dashboard, I see quite a few recent completions with amber status. Is anyone else seeing these issues?

[Hudson UI, particularly the Configure-Save response is incredibly slow at the moment, indeed Save frequently doesn't refresh at all, but Back-Configure confirms whether the change has occurred.]
