A little script I wrote to pull all of the raw objects out of a local git repo and decompress them

git_object_walker.py

import os
import zlib
import sys
from fnmatch import fnmatch

root = './.git/objects'
pattern = "*"

for path, subdirs, files in os.walk(root):
	for name in files:
		if fnmatch(name, pattern):
			try:
				filename = os.path.join(path, name)
				object_raw = open(filename, 'rb').read()
				object_full = zlib.decompress(object_raw)
				outfile = open(name + '.dump', 'wb')
				null_byte = object_full.find(b'\x00')
				outfile.write(object_full[null_byte+1:])
				outfile.close()
			except:
				print 'cannot even with ' + filename
