Description

Downloading torrents from 1337 resulting in 404 even directly from cached screen in jackett.

Should a magnet link be downloaded if the torrent fails?

The 1337x web site does not have its own .torrent cache, relying instead on 3rd party providers, such as iTorrents.org for instance. Which is why .torrents from this site are not always available when the link is followed to initiate a download.

Switching a failed .torrent download to magnet is not as simple as it first appears.
The download processor expects the given link to yield a valid .torrent file, and when it is in control is not aware that an indexer might be able to provide an alternate magnet link if the .torrent download fails.

The Jackett core processor could be amended so that it could optionally accept two download links, and so in theory the download processor could try the alternate link if the first fails.
But this will require a C# dev to provide the supporting logic, as well as amend the cardigann processor to accept two links in the download block.
Maybe someone will volunteer a PR.

Note: to make the fallback DL option available/functional, users will need to use their Jackett dashboard and edit the 1337x config and save.
Otherwise the existing config with the single DL option will continue to be active.
It is currently not possible to automate updating configs during auto-updates or over the top full installs.

Thanks! Will this be part of fresh installs going forward, though? I saw in the PR there were several config updated.

Each indexer will be updated individually to include a fallback if available, as each corresponding web site needs to be checked to determine if an alternate download is available.

For now, the upcoming Jackett release (in about 20 minutes) will include the ability to support fallback downloads, but only the 1337x indexer actually makes use of this feature.
More indexers to come as they are updated.

arenabg, badasstorrents, limetorrents, and torrentdownloads will have this setting in the next release

I'm able to think of three options for now:

1. Create an option testlinktorrent just like followredirect which defaults to true but, if false, prevents the double GETs which only selective trackers dislike.
2. We only check the torrent link if multiple download selectors are present.
3. We try to download the link in first attempt and add error handling.

Personally, I think 1st option is the best since it allows for more control over the behaviour of indexers through yml itself.
