python 压缩文件(1)
首先这里是最简单的将文件压缩成压缩文件：# -*- coding:utf-8 -*-

import os
import threading, zipfile
class AsyncZip(threading.Thread):
def __init__(self, infile, outfile):
threading.Thread.__init__(self)
self.infile = infile
self.outfile = outfile
def run(self):
state = 'w'
if os.path.isfile(self.outfile) == True:
state = 'a'
f = zipfile.ZipFile(self.outfile, state, zipfile.ZIP_DEFLATED)
f.write(self.infile)
f.close()
print 'Finished background zip of: ', self.infile
def zipDir(src,dst):
initPath = os.getcwd()
tempDST = os.path.join(os.getcwd(),dst)
tempSRC = os.path.join(os.getcwd(),src)
os.chdir( tempSRC )
files = os.listdir(os.curdir)
print files
for file in files:
background = AsyncZip(file,dst)
background.start()
background.join() # Wait for the background task to finish
os.chdir( initPath )
print os.getcwd()
#test ok
if __name__ == '__main__':
zipDir("D:\\AutoUpdate\\DataDist\\viruswall\\Data\\KSVW-VirusDB\\","d:\\AutoUpdate\\DataDist\\viruswall\\Data\\update\\KSVW-VirusDB.tgz")
显然这里压缩成功了，但是压缩采用的是zip算法。
还希望是采用 tar+ GZIP 的方式。。。。。
