And now another case

https://travis-ci.org/wikimedia/pywikibot-core/jobs/40263130

FAIL: test_image_usage_no_redirect_filter (tests.site_tests.TestImageUsage)

Test the site.imageusage() method with redirects.

Traceback (most recent call last):

File "/home/travis/build/wikimedia/pywikibot-core/tests/site_tests.py", line 698, in test_image_usage_no_redirect_filter
  self.assertFalse(using.isRedirectPage())

AssertionError: True is not false

The three builds have all been en.wikipedia.

One potential possibility is that the page stops being a redirect during the test run, in which case the 'bug' is in the test case, and not in pywikibot.

Change 171814 had a related patch set uploaded by XZise:
Identify which page is no redirect

https://gerrit.wikimedia.org/r/171814

Change 171814 merged by jenkins-bot:
Identify which page is no redirect

https://gerrit.wikimedia.org/r/171814

Okay due to the patch we now know it's not that suddenly the page became a non-redirect:

https://travis-ci.org/wikimedia/pywikibot-core/jobs/40348621#L446

So there is something else wrong.

Maybe there is a side effect. I checked all four occurences listed here and for all of them the test before 'test_image_usage_in_redirects' failed. I also checked a some other successful tests and there 'test_image_usage_in_redirects' hasn't failed.

The four also are always python 3.3 builds.

Again .. a python 3.3 build, and the error occurs after 'test_image_usage_in_redirects' failed.

https://travis-ci.org/wikimedia/pywikibot-core/jobs/40715242

Same scenario:
https://travis-ci.org/wikimedia/pywikibot-core/jobs/40988525

And again in both cases the test before that failed.

Again a failure and again the previous failed too: https://travis-ci.org/wikimedia/pywikibot-core/jobs/41080800#L483

And another
https://travis-ci.org/wikimedia/pywikibot-core/jobs/41216356

they all match the same scenario - py3, incorrect data after an exception, so im making this block our py3 port bug and increasing the importance, as incorrect data leaking across page generators doesnt sound particularly good.

And another: https://travis-ci.org/wikimedia/pywikibot-core/jobs/41313071#L483

This issue is weird as I can't see how something could get stuck, except maybe in httplib so it returns the value on the next request. Unfortunately I don't know how I could disrupt it locally so that I get that error too. I tried throwing exceptions in the loop but it didn't care.

Aklapper added a project: Pywikibot.Nov 27 2014, 4:10 PM

jayvdb moved this task from Backlog to Test failures on the Pywikibot-tests board.Nov 29 2014, 4:56 PM

And another. https://travis-ci.org/jayvdb/pywikibot-core/jobs/43413736

When nosetests is working, we can switch the 3.3 enwp build to nosetests, which .. 'should' .. give us a log.

py 3.3 is no longer supported by pwb
