Trying to unzip large files

unzip.py

# Make sure you add the -Xmx512M options or jython will throw a heap exception

# METHOD 1
import zipfile, os, sys

z = zipfile.ZipFile(sys.argv[1])
for name in z.namelist():
    destdir = os.path.dirname(name)
    if not os.path.isdir(destdir) :
        os.makedirs(destdir)
    print name
    data = z.read(name)
    outfile = open(name, 'wb')
    outfile.write(data)
    outfile.close()
z.close()

# METHOD 2
import zipfile
import zlib
import os
import sys

src = open( sys.argv[1], "rb" )
zf = zipfile.ZipFile( src )
for m in  zf.infolist():

	destdir = os.path.dirname(m.filename)
	if not os.path.isdir(destdir) :
		os.makedirs(destdir)

	# Examine the header
	print m.filename, m.header_offset, m.compress_size, repr(m.extra), repr(m.comment)
	src.seek( m.header_offset )
	src.read( 30 ) # Good to use struct to unpack this.
	nm= src.read( len(m.filename) )
	if len(m.extra) > 0: ex= src.read( len(m.extra) )
	if len(m.comment) > 0: cm= src.read( len(m.comment) ) 

	# Build a decompression object
	decomp= zlib.decompressobj(-15)

	# This can be done with a loop reading blocks
	out= open( m.filename, "wb" )
	result= decomp.decompress( src.read( m.compress_size ) )
	out.write( result )
	result = decomp.flush()
	out.write( result )
	# end of the loop
	out.close()

zf.close()
src.close()
