Two issues on default TrueNAS SCALE from macOS client

[ivan98]

I've a simple script like this running on my macOS laptop, against a TrueNAS SCALE 24.10 destination.

from truenas_api_client import Client

with Client(uri="ws://FQDN/websocket") as c:
    c.call("auth.login_with_api_key", key)
    dat = c.call("system.info")

Issue 1

Running this script gives:

(venv) ivanl@ilmac1513 truenas % ./test.py
Websocket client error: ValueError('scheme https is invalid')
Traceback (most recent call last):
  File "/Users/ivanl/Documents/src/truenas/./test.py", line 16, in <module>
    with Client(uri="ws://FQDN/websocket") as c:
         ~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/Users/ivanl/Documents/src/truenas/venv.nosync/lib/python3.13/site-packages/truenas_api_client/__init__.py", line 93, in __init__
    self.__client = client_class(uri, reserved_ports, py_exceptions, log_py_exceptions, call_timeout, verify_ssl)

    raise ClientException(self._connection_error)
truenas_api_client.exc.ClientException: WebSocket connection closed with code=None, reason=None

This is traced to the "Web Interface HTTP -> HTTPS Redirect" setting in TrueNAS UI. By default, this is enabled which causes ws: to be redirected to https which confuses middleware at port 6000.

Issue 2

Once the setting "Web Interface HTTP -> HTTPS Redirect" is disabled, the error msg changes to:

(venv) ivanl@ilmac1513 truenas % ./test.py
Websocket client error: AttributeError("module 'socket' has no attribute 'TCP_KEEPIDLE'")

macOS do not use TCP_KEEPIDLE like in Linux; instead it uses TCP_KEEPALIVE. Hence it works if line 119 in truenas_api_client/legacy.py is changed from

self.socket.setsockopt(socket.IPPROTO_TCP, socket.TCP_KEEPIDLE, 1)

self.socket.setsockopt(socket.IPPROTO_TCP, socket.TCP_KEEPALIVE, 1)

Thanks for the report! I fixed Issue 2 in #21. Issue 1 will be a bit more involved. Will fix that in a separate PR.
