import os
import threading, zipfile
import tarfile
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)
tar = tarfile.open("temp.tar","w")
for file in files:
tar.add(file)
tar.close()
background = AsyncZip("temp.tar",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")
当然还不够，因为这里虽然加入了tar环节，但是最后还是zip压缩。
