How diffs could be visible again in the RSS or Atom feeds even-though
restricting viewing of pages has been set ?

It seems like you could do that by introducing the bug that was fixed in 1.12 back into the software.

Otherwise, I don't think this is what most users would want since it provides a way around the access restriction.

Why you want this sort of control (protect the wiki, but not the diffs)? It almost sounds like you want to be using a real CMS (as the warning on the "Preventing access" page says) instead of a Wiki.

Updating summary.

Differences show content of the wiki. If read permission is restricted users without access may not view page content unless they are in $wgWhitelistRead [0].

Special:Recent_changes could be added to the whitelist, and then that page would be visible. However diffs are not visible on Special:Recent_changes so anything else that whitelisting Special:Recent_changes enables (like RSS feeds) should not show diffs either.
Else people that have Recent_changes whitelisted will be surprised if suddenly random people can see snippets of their restricted wiki through the RSS feed.

I think the situation Dieudonné wants (diffs in feeds of a read restricted wiki) should not be possible by whitelisting RecentChanges.

Maybe it was better explained there, because it is still marked as unresolved.

And I confirm the problem remains for me : I have a wiki in 1.11.2 version, and I can't upgrade it because if I do the benefit of following it's changes via the feeds is lost :(

And the configuration offered by 1.11.2 version is not a problem since people supposed not being able to access the wiki, can't access the feed either.

To access the feed on a restricted wiki (with MW < 1.11.2), I use the Brief addon on Firefox. And it's fine. Recent changes become very easy to follow and to read within Brief.
