Error in zipfile module: Zip files with no compressed files may contain only
[end of central directory record] bloc
without anything else. In that case, when _EndRecData(fpin) function tries to call:
return _EndRecData64(fpin, -sizeEndCentDir, endrec)
it makes _EndRecData64() trying to seek data in the file before the beginning of the file and generates IOError "Invalid Argument" which is :
* either badly (in is_zipfile()),
* or not catched (in __init()__._GetContents()._RealGetContents().EndRecData()).
Correction seems easy (not tested) and just need to replace:
# Try to read the "Zip64 end of central directory" structure
return _EndRecData64(fpin, -sizeEndCentDir, endrec)
by:
# check if other block are present
if filesize > sizeEndCentDir:
# Try to read the "Zip64 end of central directory" structure
return _EndRecData64(fpin, -sizeEndCentDir, endrec)
else:
# no other block present
return endrec |
