It looks like, when doing PUT together with a file-like object to send, http.client will try to send the whole file before analysing the response from the server.

If you do the following:
$ dd if=/dev/zero of=/tmp/ bs=1M count=300

And then run following code in Python 3.4 (tested 3.4.3 on Linux and FreeBSD):
import http.client
conn = http.client.HTTPSConnection('')
req = conn.request(
    body=open("/tmp/", "rb"))
resp = conn.getresponse()

You'll notice the hang. After some time, it will aborted with BrokenPipeError: [Errno 32] Broken pipe. If you run the following code within pdb debugger, and interrupt, you'll probably interrupt somewhere within write loop. You can call and see, that HTTP 413 is waiting to be interpreted.

Doing similar action with curl:
$ $ curl -v -T /tmp/

Gives you immediate HTTP 413 error. Can we have the same behaviour in http.client library?
