Unable to do range requests (regression from python-cloudfiles)

[joeshaw]

As far as I can tell, there's no way to do a partial download from cloudfiles using the Range header via pyrax.

In python-cloudfiles you could do this:

obj.read(size=8192)

But there doesn't seem to be an equivalent in pyrax/swiftclient. AFAICT the best you can do is pass in a chunk_size to fetch() but then you still have to read the rest of the data and discard it:

g = obj.fetch(chunk_size=8192)
data = g.next()
for chunk in g:
    pass

Obviously this has a pretty serious impact on performance for files of any size above the chunk_size.

That sounds like a good idea for an enhancement. In the meantime, you could manually close the connection like this:

g = obj.fetch(chunk_size=8192)
data = g.next()
cf.connection.http_conn[1].close()
