Blog feed does not validate

[crd477]

I want to subscribe to the blog in Thunderbird but the feed does not seem to validate. validator.w3.org implicates Undefined root element: atom:tag:

http://validator.w3.org/feed/check.cgi?url=https%3A%2F%2Fmirage.io%2Fblog%2Fatom.xml

Has anyone had a chance to look at this? I'd love to get notifications for new entries to your blog.

Thanks for the report, @crd477 , and your patience on a reply . @samoht @djs55 or @avsm , do you know how the RSS feed is generated (I suspect via Cowabloga)?

[djs55]

My guess is that cowabloga uses cow. This looks suspicious: https://github.com/mirage/ocaml-cow/blob/master/src/cow_atom.ml

Ah, indeed; some attention there could probably resolve this issue as well as https://github.com/mirage/mirage-www/issues/319 .

I recently watched @yomimono's 34c3 talk (great job, BTW) and was reminded of this problem. I just did some manual XML dorking and it looks like simply replacing <tag ...> and </tag> with <feed ...> and </feed> allows it to pass the W3 Feed Validation Service.

good news, everyone: I analysed and debugged the same issue as @crd477 @djs55 and provided a pull request https://github.com/mirage/ocaml-cow/pull/101 (this won't solve #319) once that is merged + released, and mirage-www is redeployed, there'll be a validating feed again :)

sorry that it took so long (and I only after debugging and opening the PR came across this issue)

https://github.com/ocaml/opam-repository/pull/11896 and https://github.com/ocaml/opam-repository/pull/11979 have been merged, and I have just re-trigered a TravisCI build for mirage-www so hopefully the feed should validate pretty soon now.

[samoht]

Re-opening as the feed is still broken ...

[samoht]

Right, it took a bit of time to shutdown the previous VM, but the new one has now valid feed. Yay!

Awesome! Thank you very much!
