Can you prove that the second one is useless (did it cause you any problem or did you just find it reading the source)? There might be reasons why there are two calls to fp.tell() (e.g. the result is different in the two places and/or zinfo.header_offset is read/changed somewhere else between the two calls). |

I just find it while reading the source, for fixing #11980 zinfo.header_offset is only read in self._write_check, and it seems to me that no file operation are performed on self.fp between the two call. So I can't see see how it could different. Also the tests suite still pass after removing the second one :) Let me know if you want me to do more investigation. |

Here is a log that shows zinfo.header_offset value after each .tell() when running test_zipfile |

I double checked the code on py3k and I think the second occurrence can be removed. |

I also can't see any file operations that might occur between the two .tell() calls, and a full test pass (including test_zipfile64) on the py3k development branch doesn't turn up any problems on Linux (2.6.38, x86_64) for me, so I agree the second .tell() could be removed. |
