PycURL RESUME_FROM
- by excid3
I can't seem to get the RESUME_FROM option to work. Here's some example code that I have been testing with:
import os
import pycurl
import sys
def progress(total, existing, upload_t, upload_d):
try:
frac = float(existing)/float(total)
except:
frac = 0
sys.stdout.write("\r%s %3i%%" % ("file", frac*100) )
url = "http://launchpad.net/keryx/stable/0.92/+download/keryx_0.92.4.tar.gz"
filename = url.split("/")[-1].strip()
def test(debug_type, debug_msg):
print "debug(%d): %s" % (debug_type, debug_msg)
c = pycurl.Curl()
c.setopt(pycurl.URL, url)
c.setopt(pycurl.FOLLOWLOCATION, 1)
c.setopt(pycurl.MAXREDIRS, 5)
# Setup writing
if os.path.exists(filename):
f = open(filename, "ab")
c.setopt(pycurl.RESUME_FROM, os.path.getsize(filename))
else:
f = open(filename, "wb")
c.setopt(pycurl.WRITEDATA, f)
#c.setopt(pycurl.VERBOSE, 1)
c.setopt(pycurl.DEBUGFUNCTION, test)
c.setopt(pycurl.NOPROGRESS, 0)
c.setopt(pycurl.PROGRESSFUNCTION, progress)
c.perform()
