python API stalling out on followers call

[John Scholvin]

I've got a script that has worked forever, which (among other things) pulls the followers for a blog. I had to write some code around it to kind of baby the calls into it, finding out the hard way that you can only request 20 at a time, and you might get fewer than 20 back. What I'm finding is that after a certain number of fetches that changes, the call into followers just never returns. This happens after returning about 600 followers for a blog that has maybe 1200. I upgraded to the latest version of pytumblr and it made no difference. Code is below. Any insight would be appreciated.

import pytumblr

import time

# Authenticate via OAuth

client = pytumblr.TumblrRestClient(

  'xxx',   # consumer key

  'xxx',   # consumer secret

  'xxx',   # oauth token  (27-Dec-2014)

  'xxx'    # oauth secret (27-Dec-2014)

)

block_size = 20

followers = True

verbose = True

blog = "xxx.tumblr.com"

if followers:

    users = []

    offset = 0

    while True:

        if verbose:

            print "grabbing followers at", offset

        response = client.followers(blog, limit=block_size, offset=offset)

        try:

            bunch = len(response["users"]) # can be fewer than requewted

        except KeyError:

            bunch = 0

        if verbose:

            print "bunch is", bunch

        if bunch == 0:

            break

        j = 0;

        while j < bunch:

            if verbose:

                print response["users"][j]["name"]

            users.append(response["users"][j]["name"])

            j = j + 1

        offset += bunch

        time.sleep(1) # to give the API a break
