{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"BrokenPipeError on KeyboardInterrupt","articleBody":"I am using the latest GitPython on pip and I have bumped into a weird behavior, that seems to be buggy. I have replicated the behavior both with Python 2.7 and 3.4 and has emerged after updating to newer versions of GitPython. Consider the following snippet (assumes a git repository on the current directory):\n\n``` [python]\nimport time\nfrom git import Repo, TagReference\n\nrepository = Repo('.')\ncurrent_commit = repository.head.commit\ntag_object = TagReference.create(repository, 'test', message='msg')\n\ntry:\n    for i in range(10):\n        time.sleep(1)\n\nexcept KeyboardInterrupt:\n    print(\"Interrupted. Exiting gracefully...\")\n\ndata = tag_object.tag.message\n```\n\nIf you interrupt (Ctrl+C) the loop, then the last statement fails with a broken pipe exception (full stack trace below). If the code is _not_ interrupted everything succeeds. Also removing the `current_commit = repository.head.commit` line, makes the problem go away, even if you interrupt a loop.\n\nI presume that it has to do with the handling of the SIGTERM emitted with a Ctrl+C, but I am not sure if this is true.\n\nThe stack trace:\n\n```\nTraceback (most recent call last):\n  File \"./bugreplicate.py\", line 15, in \u003cmodule\u003e\n    data = tag_object.tag.message\n  File \"/usr/local/lib/python2.7/dist-packages/git/refs/tag.py\", line 40, in tag\n    obj = self.object\n  File \"/usr/local/lib/python2.7/dist-packages/git/refs/symbolic.py\", line 176, in _get_object\n    return Object.new_from_sha(self.repo, hex_to_bin(self.dereference_recursive(self.repo, self.path)))\n  File \"/usr/local/lib/python2.7/dist-packages/git/objects/base.py\", line 65, in new_from_sha\n    oinfo = repo.odb.info(sha1)\n  File \"/usr/local/lib/python2.7/dist-packages/git/db.py\", line 40, in info\n    hexsha, typename, size = self._git.get_object_header(bin_to_hex(sha))\n  File \"/usr/local/lib/python2.7/dist-packages/git/cmd.py\", line 984, in get_object_header\n    return self.__get_object_header(cmd, ref)\n  File \"/usr/local/lib/python2.7/dist-packages/git/cmd.py\", line 972, in __get_object_header\n    cmd.stdin.flush()\nIOError: [Errno 32] Broken pipe\n```\n\nSome more context: I am using GitPython for `experimenter` [link](https://github.com/mallamanis/experimenter) and need a way to handle `KeyboardInterruption`s. When a Ctrl+C is pressed, I want to be able to safely store data into the git repository.\n","author":{"url":"https://github.com/mallamanis","@type":"Person","name":"mallamanis"},"datePublished":"2016-05-06T13:02:16.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/427/GitPython/issues/427"}
