Subject: [PATCH 00/??] Improve Ren'py package
Date: Fri, 02 Jul 2021 14:39:52 +0200

Hi Guix,

Being one of the first package I've ever contributed to Guix, the renpy
package contains a few mistakes, some of which were fixed over time,
but many of which still remain.  This series aims to address a few of
them.  At the time of writing, I haven't yet finished it, I just want
to claim the bug ID, so that I can 'git send-email' later today.

Thanks

Hi Leo,

Just a general comment about Python 2. :-)

Is Ren’py working only with Python 2?  Or does it also work with Python
3?  Because Python 2 is EOL, officially since January 2020, if Ren’py is
Python 2 only, maybe it could go to the channel guix-past [1], soon or
later. :-) WDYT?

Ren'py does have a Python 3 compatibility layer, but I haven't gone
around to doing a pure Python 3 build yet.  I imagine it could also be
used with Tauthon[1], which was suggested to be used as python2
replacement in places where projects can't trivially be ported to the
newer python 3 stuffs.

Furthermore, Ren'py 8 will use Python 3 as a base.  I don't know if
it'll be backwards compatible with Ren'py 7 then – probably not.  If
not, moving Ren'py 7 to Guix-Past sounds like a good idea.

I must admit, I haven't been following the Python 2 removal plan too
closely.  Is it already time to move working leaf packages?

Cheers,
Leo

It sounds like the plan is in flux, but essentially yes:

https://lists.gnu.org/archive/html/guix-devel/2021-06/msg00179.html

It seems to me that Python 2 will likely remain in Guix for some time,
but the various Python 2 packages will over time become hidden or
removed in favor of their Python 3 variants.

The Ren'Py plan is outlined here (I think?):

https://github.com/renpy/renpy/issues/2003

It sounds like it's going to be a slow (years) process for them.  Other
issues can be found here:

https://github.com/renpy/renpy/issues?q=is%3Aissue+is%3Aopen+%22python+3%22

Personally, I don't think it would be bad to add Ren'Py 7 to Guix
proper, even if it still depends on Python 2 and Python 2 libraries.
Until upstream supports Python 3, there is no other option, and for now
it sounds like we are not planning on removing all of the Python 2
libraries just yet.

If the maintenance burden becomes too great or we decide to eliminate
more Python 2 dependencies from Guix proper, we can always drop Ren'Py 7
or move it to Guix-Past along with its dependencies.  Hopefully Ren'Py 8
will bring Python 3 support sooner sooner than that, though, and we can
just drop Ren'Py 7 in favor of Ren'Py 8 at that time.

What's the motivation for doing this?  It seems like the new version
deletes duplicates, but has the downside of being a little more
complicated and relying on the package names to determine what goes into
the PYTHONPATH.

Duplicate entries in the PYTHONPATH should not be a problem for
correctness or performance, right?  I feel like this section was perhaps
better the way it was originally.  Am I missing something?

Could we pre-compile those sources on installation, instead of deleting
the common directory?  I haven't used Ren'Py much (or at all in Guix),
so I don't really understand the purpose of the common directory.  I
could just be missing some context/info.

Other than that, this patch seems OK as far as I can tell.

LGTM.  If this isn't meant to be installed by users, should it be

The reason is that I want to avoid having native-inputs in PYTHONPATH
(which the naïve getenv-based solution will always return).  For native
builds these currently can't be avoided even with the above snippet,
but for cross-builds and maybe future native-builds which separate
inputs and native-inputs, this ought to do "the correct thing".

delete-duplicates is more of a style thing than anything else, in my
personal opinion the wrapper script is more readable with it.

Leo

"Inherit" as in "use the code that was originally written for python2-
pygame-sdl2".  Did the inherit field change with this patch?  If so, I
should reflect it in the commit message.

You need Ren'py (as in the package you're currently compiling) to
compile these sources.  These sources will get compiled just fine in
the renpy package given that we already have python2-renpy available by
then, so they are shipped as part of that instead of this package.

Leo

Good point, but I don't think users will accidentally install it like
they do with gcc.  This description was written to address a point made
by Ludovic in IRC concerning the package's lack of one.  Having the
package publicly exported also makes my own life easier when updating
the recipe.  Last, but not least, these are functional modules and
could be used to develop code, that depends on Ren'py's internals, but
none of the "common" renpy stuff (or the common renpy stuff could
otherwise be extracted from the renpy package and changed to the
developer's desires).

Leo

The Python EOL is January, 1rst 2020 [1].  So now, we are 1.5 years
ahead, so yes it seems already time to cook a plan. :-)

However, there is no consensus about such plan. ;-)  Some related
discussions:

From my understanding, the “implemented” plan is described by Maxim
here:

   <https://yhetil.org/guix/87pn1oxv0m.fsf <at> gmail.com/>

I just want to point that it is less work to transfer a functional and
supported by upstream package than to transfer a package starting to
have issues.  Other said, I think it is easier to find motivation to do
the transfer for this previous case than to do some “janitor” work
later.  For what my opinion is worth. :-)

About Ren’Py 7, I do not have an opinion.  Yeah, waiting Ren’Py 8 seems
The Right Thing™ to do. :-)

Hope that helps,
simon

I know, but to be fair, we aren't the only ones behind on the Python
removal.  Python 2 is very much a zombie at this point, still kept
alive by other (mostly dead, but some live) projects that people rely
on for various reasons.

Using this plan as a starting point, I think renpy counts as a non-
variant package relying on some python2-variant.

Fair enough, I could open up a merge request to have renpy in Guix Past
"ahead of time", but OTOH I feel like `guix time-machine` offers
similar benefits.  If we're going to *mirror* python packages, because
they will soon be broken, I think it would also be a good idea to start
from python2 instead of leaf packages.

Leo

I feel like keeping it all in Guix proper but vaguely "moving things
toward Python 3 wherever possible" is the best approach for now.  An
approach like the one Maxim suggested in the above link sounds good.

Moving Ren'Py to Guix-Past would be fine, I guess, but I have to admit
it feels a little strange.  After all, Ren'Py is neither stale nor
unmaintained.  However, some of its dependencies are (like Python 2),
and their plan for upgrading to Python 3 sounds like it will take years.

OK.  I'm fine with that, then.

I see now what you mean.  It's fine.

Personally, I think the word "re-use" would have been clearer, since it
is not possible to confuse it with the "inherit" feature of package
records.

OK, I think I understand.  This seems fine.

I've changed the commit message to say "reuse" and pushed this now.  
Thanks!
