lint: Broken links reported from urlchecker #5470

davorpa · 2021-08-08T16:43:02Z

It seems that some links are down 😟 like in the past #2541. It's rare, because ci build didn't fail

Last full update: July 5, 2022

🛠️ How to proceed

First look up for an alternative link:

Try to change protocol http-https.
On the same site. Maybe was moved due to a website redesign.
In the author/editorial/publisher site
In The Wayback Machine or Unglue.it
In third-party websites, specially public libraries, universities or colleges.

If in none of ⬆️ was found, then delete it

What we could do to fix it?

Improve github action adding a cron/manual job to detect in all files ❓
Review bot config to catch bad process exits as part of Linting Errors as PR Comments #4416

Related with

The text was updated successfully, but these errors were encountered:

eshellman · 2021-08-10T13:08:54Z

The link checking CI doesn't fail because we don't want submitters to be distracted by unrelated link failures and there is a background of false negatives. We've discussed having the link checker autogenerate issues, but no one has really worked on it much.

davorpa · 2021-08-10T14:20:54Z

Yes. I've see first step would be take bot report and publish as PR comment or attach to a pinned issue as recurrent comment using a cron job.

Another good option would be send a backup to wayback machine of each link on push over master branch (merge). It could be also a cron to catch updates.

Let me research a bit more about GitHub actions, and maybe I can help.
