Posting to a frozen room should fail, but doesn't about chatexchange

[tripleee]

I'm getting a slightly better traceback with this simple demo.

#!/usr/bin/env python3

from os import environ as env
from time import sleep

from chatexchange.client import Client


client = Client('stackexchange.com', env['CHAT_EMAIL'], env['CHAT_PASSWORD'])
room = client.get_room(111121)
room.send_message('Testing')
q = client._request_queue
while not q.empty():
    print("waiting for queue to drain (%i items in queue)" % q.qsize())
    sleep(15)
client.logout()

Without the loop to wait for the queue to drain, it just quits with no indication of any error at the end of the script. (I have been wishing for other reasons that an explicit logout should make sure all messages are delivered before it disconnects, but I digress.)

The traceback shows that raise_for_status() is actually being called correctly, but there is no longer any obvious way at this point to relay the status back to the calling client.

waiting for queue to drain (1 items in queue)

https://stackoverflow.com/questions/2829329/catch-a-threads-exception-in-the-caller-thread has some ideas to explore. Ultimately perhaps an async solution would be more manageable and robust, but then that would entail giving up compatibility with Python 2 and older versions of Python 3.
