Currently, if you attempt to stream an upload from an iterator, as in
def data():
yield 'foo'
yield ''
yield 'bar'
conn.put_object('c', 'o', data())
... requests will faithfully emit a zero-length chunk, ending the
transfer. Swift will then close the connection, possibly (if Connection:
keep-alive was set) after attempting to parse the next chunk as a new
request.
Now, Swift will receive all of the bytes from the iterable, and any
zero-byte chunks will be ignored.
This will be fixed in requests [1], but not until an eventual 3.0.0
release.
