1169673 - Add RSS feed for article revisions

Status: RESOLVED FIXED

(developer.mozilla.org Graveyard :: General, enhancement)

Description

[Eric Shepherd [:sheppy]]

What problem would this feature solve?
======================================
We used to have a badly broken "revisions" RSS feed, which listed all articles which have changed recently, including in the body of each entry details about what changed (tags, review flags, content diff, etc).

The old feed was removed because the code behind it was running amok and obliterating site performance.

We need to build this feature again, from the ground up, so that it works and is regularly available for use. We have users whose preferred workflow is to see as much as possible in their feed reader so they can do all their work in one place (I admit to being one of these people).

Who has this problem?
=====================
All contributors to MDN

How do you know that the users identified above have this problem?
==================================================================
Not having this feed is a problem because without it, I'm using hacked up methods for tracking work that needs to be done. We have gotten occasional complaints about the broken RSS feeds, so I'm pretty sure this would be used if it existed and worked well.

How are the users identified above solving this problem now?
============================================================
Revision dashboard, although this is an active rather than passive mechanism for watching for changes.

Do you have any suggestions for solving the problem? Please explain in detail.
==============================================================================
Nope. It seems straightforward from my end, but I'm sure it's not. :)

Is there anything else we should know?
======================================

:groovecoder, LOE?

Comment 2

[Luke Crouch [:groovecoder]]

I'd say LOE:5 days because we could probably fix the existing feed code. E.g., the RevisionsFeed.item_description includes a call to Revision.get_previous() which makes a SELECT query for all 50 items in the feed. We could fix the Revision QuerySet to pre-fetch corresponding previous revisions.

If we think we can fix the existing code, then that's probably a smart move. We had known problems with the existing code where some changes were getting reported repeatedly, sometimes for weeks, though. I don't know if we know what would solve that.
