Antoine Pitrou pit...@free.fr added the comment: Attached test file a.zip. Happening with 2.7.1.3. The changes came with /python/branches/release27-maint/Lib/zipfile.py revision 83961 I tested with 2.7.x and 3.2 (both from latest SVN) and couldn't reproduce (I used testzip() and extractall()), both in 32-bit and 64-bit builds. Can you clarify which OS you are using? Also, what is 2.7.1.3? We don't have a such version (see http://python.org/download/releases/ for official releases). If you are using a Python provided by a third-party distributor (such as ActiveState or a Linux distribution), you might want to report the bug to them, since AFAICT the bug doesn't exist on the official builds. -- nosy: +srid ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10903 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

arindam arindampa...@gmail.com added the comment: Legacy code in my module was setting zipfile.structCentralDir to 4s4B4H3l5H2L (was added to fix some issues with older version of python) was the root cause of this issue. Sorry, should have checked before filing. Thanks for your time. Sorry once again. -- resolution: - invalid status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10903 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10903] ZipExtFile:_update_crc fails for CRC = 0x80000000
New submission from arindam arindampa...@gmail.com: File: zipfile.py Function: _update_crc statement: if eof and self._running_crc != self._expected_crc: Due to comparison of long with int, if eof and self._running_crc != self._expected_crc: fails when _expected_crc is negative (0x8000 or more). Type of _running_crc is long while _expected_crc is int. How to reproduce: Unzip a zip file containing a file having CRC = 0x8000. The issue is seen with 3.1 also. -- components: Library (Lib) messages: 126250 nosy: arindam priority: normal severity: normal status: open title: ZipExtFile:_update_crc fails for CRC = 0x8000 type: behavior versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10903 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
