Hi,

The error don't occurs all the time, only with some subtitle result.

Is it always with LegendasTV?

[tadeucruz]

Yes, but not for all results.

[morpheus65535]

I've done some changes to the scoring system in dev branch. Would you be able to give it a try? Thanks!

[tadeucruz]

Hi,

I tried but the problem still exists.
I was debugging and e found when s.archive.content != None the errors occurs.
LegendasTV uses RAR (rarfile.RarFile) or ZIP (zipfile.ZipFile) for subtitles and the look likes pickle.dumps(s) doesn't work with this king of Object.

Some time I don't have problems because on the https://github.com/morpheus65535/bazarr/blob/05fb7088f847eebc9f1fb085038a5910cfb73cc1/libs/subliminal/providers/legendastv.py#L453 check if the subtitles is in the cache and don't try download the file and set a value None to s.archive.content

Thanks.

You want to be the first member of the official Bazarr testing team? :-)

I've never had someone giving me that level of useful informations when opening an issue! Thanks a lot.

I'll look at it tomorrow, but, I can say that we are working on an issue where download_subtitles() return no content sometime. I haven't been able to pin point the root cause for now but your test give me more input.

I'll come back to you as soon as I have something to test about this issue. Thanks again.

[tadeucruz]

Hi,

Good to know that I helped with the problem. When you fix this problem I can test this case.

About testing team I can't at the moment but thanks 😃

Thanks!!

[morpheus65535]

Do you still have this issue with 0.6.7?

[tadeucruz]

Hi,

Yes.

I was looking into and I think one idea is to put this code before the serialization of the object

s.archive.content = None

Because when you call the

download_subtitles([subtitle], providers=provider, provider_configs=providers_auth)

The code in legendas.tv look if the subtitle.archive.content is None and redownload the file.

https://github.com/morpheus65535/bazarr/blob/da505bf087daa9e25c9cbb13273e586da2be8867/libs/subliminal/providers/legendastv.py#L510

Need to check with other providers does in this part of code.

[morpheus65535]

Would you like to add it and submit a PR? Or at least confirm if it fix your issue? It would be greatly appreciated as I do not use legendastv. :-/

[tadeucruz]

Yes,

I'll work in PR this weekend.

Thanks.

[pannal]

This issue has always been there with the legendastv provider. It'll be fixed when subliminal_patch is integrated.

Legendas tries to cache the archive stream data inside dogpile, which fails.

[morpheus65535]

BTW I've merged your PR to dev branch. Could you give it a try? Thanks!

[tadeucruz]

Hi, sorry for the delay.

I tested and everything looks fine.

Thanks.

[morpheus65535]

I'm going to merge it to master in next version. Thanks!
