Serhiy Storchaka added the comment: The specification of ZIP files is not pretty clear, but the unzip utility first try to interpret offsets relatively to the start of the archive that can be different from the start of the file. Go's standard archive/zip package interprets offsets as absolute file positions and doesn't support concatenated ZIP files.
In any case there is a regression. Proposed patch partially reverts issue26293. Offsets in created ZIP file are now absolute when create with modes 'w' and 'x'. But they are relative when create with mode 'a'. This should fix a regression in pex, but keep the case of issue26293. I'm going to push the patch before tagging 3.5.3 rc1. ---------- keywords: +patch nosy: +benjamin.peterson, larry, ned.deily priority: normal -> release blocker stage: -> patch review type: -> behavior versions: +Python 3.5, Python 3.6, Python 3.7 Added file: http://bugs.python.org/file46107/zipfile_write_absolute_offsets.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29094> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
