[PATCH 0/1] configure: prefer python's sphinx module

[John Snow]

Hi, this is a followup to my patch which attempted to prefer
'sphinx-build' to 'sphinx-build-3' which intended to prefer a VENV
installation of sphinx over Fedora's system installation.

That got confusing, though, so here's something that's simpler and
better: use python to invoke sphinx so we don't have to worry about
python/sphinx version mismatches.

This should essentially always DTRT. In cases where a specific sphinx is
preferred, you would use a virtual environment with sphinx installed and
configure QEMU with e.g. --python /path/to/my/venv/python35

[PATCH 1/1] configure: prefer python's sphinx module

[John Snow]

Using an explicit entry path script for sphinx can lead to confusing
results: If the python binary belongs to a virtual environment, our
configure script may still select a sphinx script that belongs to the
system distribution packages.

It is likely best to use python itself (whichever one the user provides)
to resolve the sphinx script. This has a few benefits:

1. It will always be Python 3. Script entry points like 'sphinx-build'
might attempt to invoke python2 -- or indeed, any version of python that
the user did not specify with --python.

2. When using a user installation of sphinx, it will naturally prefer
that version.

3. When using a virtual environment, it will naturally prefer that
version.

4. Removing explicit python script entry points gives us greater control
within the QEMU build ecosystem; we can be confident we are respecting
the user's --python configuration, if any.

It's my hope that this will make it simpler to integrate some optional
pipenv functionality into the build for adding regression testing to our
python module -- by offloading more of the python environment
configuration and testing directly to the python tooling ecosystem.

This would, ideally, free us up to use more modern python packages not
always offered in older system distributions. (For instance, we already
violate this requirement with sphinx, which does not have the necessary
versions in our oldest build platforms.)

I'm not convinced. How do I find out which sphinx-build this
is actually going to use ? ("python3 -m sphinx" doesn't list a
path to anything.)

How do I use the system python but a venv sphinx-build? At the
moment I can easily do that with
  --sphinx-build=/home/petmay01/python-env/bin/sphinx-build
because scripts inside a venv have #! lines that make them
work without having to manually activate the venv. I don't
want to have to use some random non-system Python just
because I have a newer Sphinx.

Put another way, I don't think the fact that sphinx-build
happens to be implemented in Python means that we should
let the user's decision about which Python they want us to
use control which version of sphinx-build we should use.

thanks

The venv uses symlinks, so it will continue to use your system version,
but you can install sphinx here.

I'm proposing you do either one of:

A) ./configure --python=/home/petmay01/python-env/bin/python3

B) source ~/python-env/bin/activate
   ./configure

I was under the impression that it would be best if sphinx was executed
using the user's specified python binary instead of allowing
scripts/qapi to run under the user's python but sphinx to run under a
different python.

One of the reasons I came to this belief was to ensure that when
operating inside of a venv that QEMU was always using that venv's python
and sphinx instead of "leaking" out to the system's installation. It
felt more explicit.

A problem with looking for 'sphinx-build-3' and 'sphinx-build' entry
scripts is that the /usr/bin/xxx namespace is shared between python2 and
python3 packages and we may wind up selecting a sphinx for the wrong
python version entirely -- and from what I could tell, there wasn't a
way to interrogate sphinx to get it to tell us what python it was using,
or any other way to force this kind of scripted entrypoint to use *my*
python.

Fedora gets into trouble here because we want 'sphinx-build-3', but this
ignores our venv version because the script entrypoint in a venv is
'sphinx-build' -- which might be the system's python2 version.

Using `python -m sphinx` seemed nice because:

1. Works the same inside and outside of venv
2. Don't need to interrogate python version, we already know it
3. We are confident it uses the venv.

Or, put another way, I think it's quite odd to:

1. Activate a venv
2. Specify an explicit python version to ./configure
3. Have sphinx use a python/sphinx that is not necessarily correlated
with either #1 or #2.

I see your point: Why not treat sphinx-build as a black box executable
instead of treating it like a python plugin?

Mostly,

(1) The aforementioned problems locating and interrogating the correct
script entrypoint to use based on the user's environment and configure
options

(2) By treating it as a Python dependency instead, I can ensure that we
have a correctly modern sphinx in a venv as a repeatable build step for
platforms that do not ship a modern-enough sphinx.

This seems strictly worse than what we have now (where I can
just tell configure to use the sphinx-build I want it to).
I don't want to do A because I'd rather just use the system
python, and I don't want to use B because it requires an
entire extra step (and also I think it will end up using the
python from the venv rather than the one from the system).

I'm not sure that's right. We should run sphinx with whatever
python it wants to run as, not feed it something different
it doesn't expect.

Well, if we're in a venv then by default it makes sense for us
to be using the venv's setup.

configure's checks should mean we reject a sphinx-build
that uses a too-old python, though.

Mmm. That seems to me like it's basically Fedora having made a
mistake :-) Maybe we should say "try sphinx-build, if that
exists and works then great, otherwise try sphinx-build-3 next" ?
