Thanks for the patches!

I'm going to review these superficially; I won't try to actually build
or run them until the django test suite is ready to be tested, unless
you can tell me how to do so.

We use the phrase "New variables" when adding new package definitions to
an existing package module.

Can you say what the difficulty is? We prefer to run upstream tests when
possible.

Did you check if this is really needed? Usually, only the python-2
package variants require setuptools as an input. You can see commit
13f3ff35 for an example of how to do this.

A nit-pick, but it would be nice if this was a little less
"conversational". That is, things like "That's it! What you do [...]"
can be removed.

Should the maxminddb be packaged so that we can run the tests?

Can you explain to the reader what the purpose of the MaxMind DB is?

I see you already know to use the python2-variant system. Feel free to
move setuptools here if that works for python-maxminddb.

The maxminddb database?

If setuptools is necessary, it should typically be a native-input, since
it is typically only used at build-time; there are a few exceptions. Is
that not the case for geoip2?

Again, can you give a little more context for the reader?

Can you add a comment explaining why we have to replace the check phase
and what these options are doing?

Please see the package definition of python-debian for an example of how
to make these sorts of lists in texinfo (which is what the description
is).

You can figure out where package foo is defined with `guix package
--show=foo`. That is more discoverable than a comment in the code base.

Is this running the python3 interpreter with no arguments in order to
see if it exists, and then doing 2to3 if it does?

I'll briefly answer on your comments. Please not that mot motivation for
including these tests is solely to enhance the django test-suite.

When installing the package, this database in not installed. The
installation instructions of that package does not a hint on it. I
assume this database being quite large (several GB), since it contains
geo-information. I would not require everybody rebuilding this package
to download that much data.

Sorry, I can't. it is used by geoip2 and this is the reason for
including it.

Pardon? That's all the project seay. What more would you expect?

Ack. I asume one could do this by manipulating the output of
"packaged-wiht-python2". But I only learned of how to manipulate this
long after.

Also, the output of --show is in the recutils format [0], so if you
install recutils, then you can do things like this:

$ guix package --show=python-requests-mock | recsel -P location 
gnu/packages/openstack.scm:238:2

Yeah, it's hard to invent a description when the upstream doesn't
provide it.  What about this:

  IPaddr is a fast and lightweight Python library used to create and
  manipulate IPv4 and IPv6 addresses and networks.

This is derived from the python module description:
<https://github.com/google/ipaddr-py/blob/master/ipaddr.py>

Note: I'm bad at writing descriptions.

Alternatively, you can do "guix edit foo" and look what module it is.

Sounds good!

But yeah, I agree that it’s hard to do any better if upstream doesn’t
even bother.

(For the record, Hartmut,
<https://www.gnu.org/software/guix/manual/html_node/Synopses-and-Descriptions.html>
gives guidelines about these things.)

Thanks,
