Hi,

these two patches add couchdb. First, an upgrade to erlang is essential, since
our version is quite outdated and has known issues with couchdb. I’m only
bumping to a newer maintenance release of 21.x for now. `guix refresh
--list-dependent` lists only elixir, which builds fine with the new version and
emacs-erlang, build from the same sources, seems to work too.

The second patch adds couchdb. I’ve got almost the entire test suite up and
running. It is very extensive and takes a lot of time (compared to
compilation). Some patching is required to unbundle Erlangs ERTS, so an update
to Erlang in the future might break 'install due to the hard-coded version. Any
thoughts?

Future work: Shepherd service.

Cheers,
Lars

I've pushed the erlang update for now. I haven't taken a look at the
couchdb package at all as of yet.

I touched up the couchdb patch a bit and there were a couple of things
that stood out to me. The test suite passed for me without any problems.

There are a couple of bundled fonts as well as bundled javascript inside
the share directory, which also makes it to the output.

Looking at %out/lib/ it looks like there are a bunch of other libraries
bundled with couchdb. I don't know much about erlang but I assume all
these libraries should be unbundled. Looking inside erlang I see there
are also a lot of what looks like bundled libraries so I'm not really
sure how that goes.

On the other hand, after talking to you on IRC and looking at how Debian
takes erlang¹ and seems to split it into dozens of package outputs I'm
far more uncertain of how it works.

Anyway, take a look at the changes I made and see if anything/everything
works :)

Hi Efraim,

we can probably unbundle fontawesome, but not their own font. The web frontend
(fauxton) depends on NPM and a bunch of JavaScript packages – nothing we can do
about that.

As far as I see there is a mix between bundled external libraries and those
internal to couchdb. External libraries in src/ are:

- bear (https://github.com/boundary/bear)
- dreyfus (https://github.com/cloudant-labs/dreyfus)
- folsom (https://github.com/boundary/folsom)
- hyper (https://github.com/GameAnalytics/hyper)
- jiffy (https://github.com/davisp/jiffy)
- meck (https://github.com/eproxus/meck)
- mochiweb (https://github.com/mochi/mochiweb/)
- proper (https://github.com/proper-testing/proper)
- rebar (https://github.com/rebar/rebar)
- recon (https://github.com/ferd/recon)
- snappy (https://github.com/skunkwerks/snappy-erlang-nif)

All modules are also mirrored by the Apache project here
https://github.com/apache?q=couchdb&type=&language=
so it might be possible to build most of them “out of tree”, i.e. create
separate packages and somehow “link” to them. I’ll look into that when I have
some time, but I’m not an Erlang guru. In the meantime I’ll be maintaining the
package over here[1], since the current state is not good enough for inclusion
into guix.

Yep, I can confirm the server and web interface are working.

Thanks for the review,
Lars

Alright, what is the status of this patch? Does it need more work? Or is
it ready?

Hi,

I don’t have time to work on this any more. The package works fine, but
probably does not satisfy guix’ requirements regarding bundled and precompiled
(JavaScript) sources.

Oh well, that's too bad. I'll close this ticket and anyone should feel
free to reopen it if they'd like to continue the work.
