BlockList class is obsolete

[huguesv]

We no longer use this class to submit block list. We now use a list of strings. Not to be confused with BlobBlockList, which is used to receive block lists.

The code that is obsolete is:

class BlockList(WindowsAzureData): ''' BlockList used to submit block list. '''

def __init__(self):
    self.committed = []
    self.uncommitted = []
    self.latest = []
