Plugin throws an exception and fails if connection to MusicBrainz fails

[Maxr1998]

Occasionally, my ISP assigns me a shared IP that's banned by MusicBrainz/ListenBrainz, causing listen submission to fail. This failure is expected. However, it appears that the retry policy doesn't actually work in that case. Additionally, it doesn't print the raw JSON request (anymore). I think this was introduced when recording attributes started to be resolved through MusicBrainz directly.

Yeah, this should be fixed pretty easily by handling that cancellation exception.

Additionally, it doesn't print the raw JSON request (anymore).

The request should be in the log as the request is logged before it is sent. Or do you mean that the subsequent requests are not logged? That sounds like a complete plugin crash.

I think this was introduced when recording attributes started to be resolved through MusicBrainz directly.

MB is integrated basically from the beginning as Jellyfin does not store recording MBIDs. Or do you think that IP got banned because of this plugin? I can think of a scenario where it could happen, but that depends on multiple assumtions and I'm not sure if it would be realistically possible.

I was referring to the JSON that's logged for the HTTP request, like this:

Jellyfin.Plugin.Listenbrainz.ServerEntryPoint:
Sending request (98e159b>
Method: POST
URI: https://api.listenbrainz.org/1/submit-listens
Data: {"listen_type":"single","payload":[…]}

This wasn't logged when the requests didn't go through, but would have been useful.

I think I misunderstood 37288baefb0564ce1f4d5025d1687fba051b6127 back then, sorry the confusion.

No, I doubt that's the reason, it's just that my ISP regular assigns me a new IPv4 address, usually nightly, and I was simply unlucky to have received one that was previously banned.

I see, you mean the ListenBrainz one. That actually makes sense, since the plugin is too busy crashing.

Anyway, I improved the handling of exceptions in #21. Now the exception should be caught and eventually a retry exception should be raised for the MB request, which in turn should allow LB client to attempt submit without MB metadata.

If you want, you can get the new plugin build from this job.

Thank you! I'll give the preview build a test run and report back if I encounter any issues.
