KeyError when i get subscription list

[gu1llohm]

Hey hey !!

First, thanks for your job, this is amazing ! I tested it on a linux machine connected to a tons of Dante devices.
When i'm trying netaudio subscription list, not every time, i get in the list, a lot of :

timed out getting mDNS service
or
Failed to get a service by type.
or
Failed to get Dante device name

then a correct list of devices, and for finishing :

KeyError

69

at /usr/local/lib/python3.9/dist-packages/netaudio/dante/subscription.py:25 in status_text
21│
22│ return text
23│
24│ def status_text(self):
→ 25│ return subscription_status.labels[self.status_code]
26│
27│ def to_json(self):
28│ as_json = {
29│ "rx_channel": self.rx_channel_name,

let says, this error is happening 4 / 10.

Do you have an idea how to workaround this ?

Thanks for your help !

I need to implement a configurable timeout for mDNS and/or some server that runs separately that is always checking for devices. It's currently set to 1.5 seconds in a few places; check the code for DanteBrowser(mdns_timeout=1.5) if you want to override it. If you send commands with an IP address it will talk directly to the device and doesn't use mDNS at all. Since you have a lot of devices, it would be interesting to hear how many of them report channel counts and other information correctly. Any problems there? I of course can't test every device. I just looked at it and this particular status code is SUBSCRIPTION_STATUS_RX_UNSUPPORTED_SUB_MODE, which is something I just got on any of my devices. I should make this at least check for unlabeled status code types and give some generic message at least.

Thanks Chris !
I can modify your work, but maybe it will be more accurate to add as an argument this mDNS timeout in your project ?
If you are interested to get forward on this project, we have a perfect test environment for it ( more than 100, different types ).
Please contact me in PM gro@acs-cabling.com. Many thanks.

Dear Chris,
Do you know how to tell properly as an argument for listening a specific network interface ?

[chris-ritsen]

The configurable mDNS timeout is done, but the branch hasn't been merged yet. Will look into specifying a network interface.

Thanks Chris ! About KeyError, i bypass the issue using netaudio/dante/subscription.py, remplacing line 38 :

return SUBSCRIPTION_STATUS_LABELS.setdefault(self.status_code, f"Unknown status ({self.status_code})")
