Reading corrupted/partial zip files in python (See related posts)

First a simple script for reading non-corruted zipfiles in python:

filename = 'foo.zip'

import zipfile

z = zipfile.ZipFile(filename)

for i in z.infolist():
    print i.filename, i.file_size

z.read('somefile')


Next we use 'zip -FF foo.zip' to fix the zipfile, before reading it:

filename = 'foo.zip'

import zipfile

try:
    z = zipfile.ZipFile(filename)
except zipfile.BadZipfile:
    import commands
    commands.getoutput('zip -FF '+filename)
    z = zipfile.ZipFile(filename)

for i in z.infolist():
    print i.filename, i.file_size

try: 
    z.read('somefile')
except zipfile.BadZipfile:
    print 'Bad CRC-32'



In short: use 'zip -FF file.zip' to fix the file. It will restore the filelist.
