Most of the relevant build machinery is in the Makefile. And looking at this 
there’s already precedent for checking for macOS there, “python-config” is a 
shell script on all platforms except macOS, and the makefile fragment for 
building it checks if we’re on macOS without using autoconf.

In the end it is a workaround for a platform feature that’s causing problems, 
but Python.app in the framework build is a proper app bundle.  Using a shell 
script for the same functionality is a hack (he says without having looked at 
that script) ;-)

on a personal level, it's because the conda folks really want to use a
plain vanilla unix build -- and I want things to work with conda.

As to why conda wants to do that, my thoughts:

conda manages not just Python, but also a full set of other libraries, and
even other languages (R, Julia, Java).

In that way, it's a bit like homebrew or macports.

However, It also tries to be as platform-neutral as possible, so anything
that works one way on conda works that same way on all platforms.

And in practice, it solves a LOT of problems, problems that were a pain in
the neck for years on the Mac.

Also in practice, treating OS-X as "just another unix" works quite well in
almost all ways -- there are a few addicted here than there, though those
are mostly about clang than OS-X per se. But most things "just work".

Another practical consideration is that the vast majority of Python
developers that use Macs use them like a Unix system: data analysis, web
development, etc, etc. It's only desktop GUI software that poses any
issues, and this is the only issue (that I know of) for that.

There was an experiment with using a Framework build in conda a while back
-- it immediately ran into the issue that it would be incompatible with all
existing conda-python packages, so that's not good. It could be that that
could be addressed with appropriate symlinks, but not one did a thorough
testing.

Another issue is that conda now supports platform-independent Python
packages -- and that would get a lot harder with a Framework build. (though
again, maybe a full set of links could solve that)

It's also the case that using a Framework build inside conda buys us
absolutely nothing -- it just makes things gratuitously different from the
other *nix systems for no gain. I appreciate the idea of frameworks, but a)
I don't think Frameworks were really designed for things like python
anyway, and b) conda is solving all the problems that Frameworks solve but
-- in a different, and platform independent way.

In short: building python as a framework in conda would create an
incompatibility with no gain. The only reason to do it would be to get the
"pythonw" executable, and that doesn't actually require a Framework --
"just" some new build scripts.

Anyway, if the folks that want this do the work, it looks like it can
happen, and if not, then I guess we won't get it.

Fair enough.

Christopher,
it still isn't clear to me _why_ you wouldn’t want to use a framework build…

The whole exercise feels a bit like discussions from 15 years ago, with Unix 
wizards who wanted MacOS to behave as if it was plain vanilla Unix without all 
the things Apple changed. And that is much less true today than it was then…

Glad to hear that -- in earlier conversations, I got the impression that
you thought the executable wrapper was kind of a hack :-).

Maybe they should switch to a framework build instead :-)

As mentioned on python-dev adding the “pythonw” functionality to the unix build 
is not very hard. I expect that integrating with the build system 
(Makefile/configure script) will be the hardest part due to introducing 
different behaviour for the macOS platform.

The framework build does not have a workaround for these problems, it has a 
proper solution ;-).

It's interesting that brew python has decided to use a Framework build 

But the problem at hand is conda python which used a plain unix build.

They have provided a shell script "pythonw" that re-directs to a python
inside an app bundle, and that works OK on the command line, but it does
not work with, e.g. setuptools entry points.

I could dig up the threads, but this has been discussed on this list, and
few gitHub issues.

In short, there are a few ways to work around these issues, but no one (the
conda people, the setuptools devs) wants to put the kludgy work around in
their code.

And we already have a work around in the core python code, it's just that
the build system needs to be set up to build it outside of a Framework.

Re: [Pythonmac-SIG] "pythonw" in a Unix build

2021-01-14 Thread Jack Jansen 
I’m not sure there is a point anymore?

For example, the brew Python is installed into a framework tucked away deep in 
/usr/local/Cellar but you don’t notice this at all: you can just use “python 
foo.py” and the moment the script does GUI calls it’ll get an icon in the doc 
and all that.

What problem are you trying to solve?

[Pythonmac-SIG] "pythonw" in a Unix build

2021-01-14 Thread Chris Barker via Pythonmac-SIG 
Ned suggested I bring this conversation over here from python-dev, so here
it is.

What I'd like to see done is have the "pythonw" wrapper buildable in an
otherwise non-framework build.

I *think* there are no real technical show stoppers, but it would take some
auto-conf magic, which I am fully unqualified to take on.

Anyone interested in helping make this happen ?
