{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Fix \"known\" Windows errored test cases","articleBody":"Currently, _Windows_  TestCases on Appveyor established on #519 are [\"artifically\" ok](https://ci.appveyor.com/project/ankostis/gitpython/build/1.0.199).\nBecause in the code, the Test Cases known to fail on have been marked with the [`HIDE_WINDOWS_KNOWN_ERRORS`](https://github.com/gitpython-developers/GitPython/blob/master/git/test/lib/helper.py#L38) variable so that we get an ALL GREEN response; that way we can _detect when new commits break additional TCs on Windows_.\n\nCurrently there are 10 failing TCs (search them with the above var-name), and you can view the errors in this Appveyor job:\n\n  https://ci.appveyor.com/project/ankostis/gitpython/build/1.0.196\n\nThe errors are mostly related to 2 issues:\n1. **Unicode:** for those with reading time, I would suggest these 2 contradictory sources: \n    - problem: [Everything you did not want to know about Unicode in Python 3](http://lucumr.pocoo.org/2014/5/12/everything-about-unicode/)\n    - solution: [PEP 383 -- Non-decodable Bytes in System Character Interfaces](https://www.python.org/dev/peps/pep-0383/) - so using text-mode \n2. **Leaked resources:** these are (possibly memmory-mapped) files that are not deallocated (and hence, not deleted afterwards). Unfortunately, dealing with them might mean that you have to jump projects, as some are inherited from the library projects [_smmp_](https://github.com/gitpython-developers/smmap) and (mostly) [_gitdb_](https://github.com/gitpython-developers/gitfb).\n\nIn order to reproduce the failed TCs on your PC, change locally [`git/test/lib/helper.py:#L38`](https://github.com/gitpython-developers/GitPython/blob/master/git/test/lib/helper.py#L38) from this:\n\n``` python\n    HIDE_WINDOWS_KNOWN_ERRORS = os.environ.get('HIDE_WINDOWS_KNOWN_ERRORS', True)\n```\n\ninto this:\n\n``` python\n    HIDE_WINDOWS_KNOWN_ERRORS = os.environ.get('HIDE_WINDOWS_KNOWN_ERRORS', False)\n```\n\nThis issue is about not forgetting these TCs - _asking for help to fix them_.\n","author":{"url":"https://github.com/ankostis","@type":"Person","name":"ankostis"},"datePublished":"2016-10-03T02:33:47.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/525/GitPython/issues/525"}
