fetchart hangs forever if server doesn't respond

Problem

Running this command in verbose (-vv) mode:

$ beet -vvv fetchart album:"TRON: Legacy R3C0NF1GUR3D"

Led to this problem:

<hangs indefinitely>

https://coverartarchive.org/release/d0ddc2ca-5300-38ba-bb7d-83053369319c redirects to https://archive.org/download/mbid-d0ddc2ca-5300-38ba-bb7d-83053369319c/index.json but archive.org is currently down.

Setup

• OS: NixOS 24.11 (Vicuna)
• Python version: 3.12.5
• beets version: 2.0.0 (although beet version reports 1.6.1 because 33ab22d didn't make it into 2.0.0)
• Turning off plugins made problem go away (yes/no): plugin issue

My configuration is:

fetchart:
  sources:
    - filesystem
    - itunes
    - coverart
    - amazon
    - albumart

Interestingly we do set a timeout but it hangs anyway:

beets/beetsplug/fetchart.py

Lines 271 to 272 in 03f1205

	if "timeout" not in send_kwargs:
	send_kwargs["timeout"] = 10

Hopefully archive.org is back soon: https://x.com/brewster_kahle/status/1844790609573277792

Trying to curl your URL gives me

$ curl https://coverartarchive.org/release/d0ddc2ca-5300-38ba-bb7d-83053369319c -L
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the webpage mentioned above.

fetchart returns a similar error and does not hang on my side:

fetchart: downloading image: https://coverartarchive.org/release/d0ddc2ca-5300-38ba-bb7d-83053369319c
fetchart: error fetching art: HTTPSConnectionPool(host='archive.org', port=443): Max retries exceeded with url: /download/mbid-d0ddc2ca-5300-38ba-bb7d-83053369319c/index.json (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1007)')))

[jackwilsdon]

I think I was attempting this whilst archive.org was actively being DDoS'd, so curl would hang at Trying <archive.org ip>:443... after the coverartarchive.org redirect.

I feel like there's probably still an issue here, as fetchart shouldn't hang if a service never responds.

[jackwilsdon]

I can't reproduce this now even if I try it with a test server that hangs in the same way archive.org did (no ACK).

I still have this problem, either it makes it through after some (mostly very long) time or just hangs forever. But it never times out. I guess disabling fetchart or using a different source is best for now?

[snejus]

You can try excluding the coverart source by specifying every other one in your configuration:

fetchart:
  sources:
    - filesystem
-   - coverart
    - itunes
    - amazon
    - albumart
    - wikipedia
    - google
    - fanarttv
    - lastfm
    - cover_art_url

Since I've got store_source: yes configured, you can see which ones have been useful in my library:

$ beet list art_source::.. -f '$art_source' | sort | uniq -c | sort -n
      1 fanarttv
      7 wikipedia
     19 lastfm
     22 spotify
    118 cover_art_url
    320 coverart
    386 filesystem
   1950 itunes
   3985 bandcamp

Reopening as I can reproduce this again and I think I've found the root cause. We have a timeout set for _logged_get, but we don't set one when we're actually downloading the artwork:

beets/beetsplug/fetchart.py

Lines 364 to 366 in f8b1071

	self.request(
	candidate.url, stream=True, message="downloading image"
	)

By default, requests has no timeout, but it does end up timing out eventually (seemingly after a few minutes). We should set a reasonable timeout here (maybe 10s like in _logged_get?)

I've also noticed that the Wikipedia source has a timeout of 2500 seconds, which seems a bit high - maybe it was meant to be 2.5s?

Interestingly, the link opens just fine in my browser, so the archive server doesn't seem to be down at the moment?
UPD: never mind, that was just cached
