Hi,

there is at least one broken package on NonGNU ELPA
(color-theme-tangotango) that was added, then removed as dependencies
were missing, but it remained in the archive because it was added to the
archive-contents file.  The following patch would make sure that any
package not listed in elpa-packages is also remove from
archive-contents:

It might be a good idea to cache the interpretation of elpa-packages, so
I would also suggest the following:

While this would fix the above problem, two points remain:

1. This does not remove any tarballs.  It wouldn't be hard to do, but I
   am not sure if there would be any unintended side effects of doing
   so -- at least immediately.

2. There are functioning packages on NonGNU ELPA like haskell-mode that
   were also added to elpa-packages then removed, and still linger in
   the archive without being updated.  This would get rid of those too,
   which might not be a good idea.

Thanks, but I don't think `elpaa--update-archive-contents` is the right
place for that.  This can be called N times for a given invocation of
`elpaa-batch-make-all-packages`.
Why not call a dedicated function from `elpaa-batch-make-all-packages`
(i.e. alongside the call to `elpaa--publish-package-specs`)?

Not sure it's worth the trouble: the way the code is written, it should
be called only once per Emacs session in the majority of cases, no?

I think we should keep the old HTML page and tarballs.

Indeed, `haskell-mode` should be re-added to `elpa-packages`
because IIRC it's still actively depended-upon (by GNU ELPA's `hcel`).

That can be done.

Right, ideally somewhen around the beginning.

I agree.

The issue here is that upstream isn't responsive and has asked for
haskell-mode to not be added until further notice :/

I'm copying in the haskell-mode maintainer Steve Purcell.

If necessary, we could also revert to what we were doing initially with
the :version-map, preventing any updates but ensuring the package is
available.

Hmm... in `elpaa--scrub-archive-contents` you `elpaa--get-specs` but you
could skip that if you called this function a tiny bit later and passed
`specs` to it instead, right?


        Stefan


PS: Haven't really looked at the rest of the patch, actually, this part
just jumped at me.  But now that I see how this is more complex than
your original patch, maybe doing it N times is the better option (and if
not, we can add a global boolean var telling us if we've done it
already).

No, you are absolutely right, I just didn't see that.
