[PATCH v3 00/15] Python: packaging cleanups

[John Snow]

This series is a collection of touchups and small fixes to the Python
packaging series that was initiated with commit ea1213b7.

It fixes a small handful of annoyances and adjusts some readme files,
help text, and so on.

I'd like to make sure this is included prior to the 6.1 RC testing
period. (And now, at the very least, patch #01 needs to go in ASAP.)

V3:
  001/15:[down] 'python/qom: Do not use 'err' name at module scope'
  010/15:[down] 'python: only check qemu/ subdir with flake8'
  015/15:[down] 'python: Fix broken ReST docstrings'

 - 01: Update library for pylint 2.9.0 which happened ~2hrs ago
 - 10: Fix pylint checking stuff it shouldn't (Wainer)
 - 15: Also new, it helps me along with Sphinx doc work.

V2:
  007/12:[0002] [FC] 'python: update help text for check-tox'
  008/12:[down] 'python: Fix .PHONY Make specifiers'
  009/12:[down] 'python: add 'make check-dev' invocation'

 - 07: Changed '3.6-3.10' to '3.6 - 3.10'.
       (Kept Willian's RB)
 - 08: New, based on Wainer's observation I had missed 'check-tox'.
 - 09: Renamed targets based on Wainer's review.

[PATCH v3 01/15] python/qom: Do not use 'err' name at module scope

[John Snow]

Pylint updated to 2.9.0 upstream, adding new warnings for things that
re-use the 'err' variable. Luckily, this only breaks the
python-check-tox job, which is allowed to fail as a warning.

I guess that's good enough evidence that check-pipenv and check-tox both
have their place :)

[PATCH v3 02/15] python: expose typing information via PEP 561

[John Snow]

https://www.python.org/dev/peps/pep-0561/#specification

Create 'py.typed' files in each subpackage that indicate to mypy that
this is a typed module, so that users of any of these packages can use
mypy to check their code as well.

Note: Theoretically it's possible to ditch MANIFEST.in in favor of using
package_data in setup.cfg, but I genuinely could not figure out how to
get it to include things from the *source root* into the *package root*;
only how to include things from each subpackage. I tried!

[PATCH v3 03/15] python: Remove global pylint suppressions

[John Snow]

These suppressions only apply to a small handful of places. Instead of
disabling them globally, disable them just in the cases where we
need. The design of the machine class grew quite organically with tons
of constructor and class instance variables -- there's little chance of
meaningfully refactoring it in the near term, so just suppress the
warnings for that class.

[PATCH v3 04/15] python: Re-lock pipenv at *oldest* supported versions

[John Snow]

tox is already testing the most recent versions. Let's use pipenv to
test the oldest versions we claim to support. This matches the stylistic
choice to have pipenv always test our oldest supported Python version, 3.6.

The effect of this is that the python-check-pipenv CI job on gitlab will
now test against much older versions of these linters, which will help
highlight incompatible changes that might otherwise go unnoticed.

Update instructions for adding and bumping versions in setup.cfg. The
reason for deleting the line that gets added to Pipfile is largely just
to avoid having the version minimums specified in multiple places in
config checked into the tree.

(This patch was written by deleting Pipfile and Pipfile.lock, then
explicitly installing each dependency manually at a specific
version. Then, I restored the prior Pipfile and re-ran `pipenv lock
--dev --keep-outdated` to re-add the qemu dependency back to the pipenv
environment while keeping the "old" packages. It's annoying, yes, but I
think the improvement to test coverage is worthwhile.)

[PATCH v3 05/15] python: README.rst touchups

[John Snow]

Clarifying a few points; removing the reference to 'setuptools' because
it isn't referenced anywhere else in this document and doesn't really
provide any useful information to a Python newcomer.

Adjusting the language elsewhere to be less ambiguous and have fewer
run-on sentences.

+Using these packages without installing them
+--------------------------------------------
+
+These packages may be used without installing them first, by using one
+of two tricks:
+
+1. Set your PYTHONPATH environment variable to include this source
+   directory, e.g. ``~/src/qemu/python``. See
+   https://docs.python.org/3/using/cmdline.html#envvar-PYTHONPATH
+
+2. Inside a Python script, use ``sys.path`` to forcibly include a search
+   path prior to importing the ``qemu`` namespace. See
+   https://docs.python.org/3/library/sys.html#sys.path
+
+A strong downside to both approaches is that they generally interfere
+with static analysis tools being able to locate and analyze the code
+being imported.
+
+Package installation also normally provides executable console scripts,
+so that tools like ``qmp-shell`` are always available via $PATH. To
+invoke them without installation, you can invoke e.g.:
+
+``> PYTHONPATH=~/src/qemu/python python3 -m qemu.qmp.qmp_shell``
+
+The mappings between console script name and python module path can be
+found in ``setup.cfg``.

[PATCH v3 07/15] python: rename 'venv-check' target to 'check-pipenv'

[John Snow]

Well, Cleber was right, this is a better name.

In preparation for adding a different kind of virtual environment check
(One that simply uses whichever version of Python you happen to have),
rename this test 'check-pipenv' so that it matches the CI job
'check-python-pipenv'.

Remove the "If you don't know which test to run" hint, because it's not
actually likely you have Python 3.6 installed to be able to run the
test. It's still the test I'd most prefer you to run, but it's not the
test you are most likely to be able to run.

Rename the 'venv' target to 'pipenv' as well, and move the more
pertinent help text under the 'check-pipenv' target.

[PATCH v3 08/15] python: update help text for check-tox

[John Snow]

Move it up near the check-pipenv help text, and update it to suggest parity.

(At the time I first added it, I wasn't sure if I would be keeping it,
but I've come to appreciate it as it has actually helped uncover bugs I
would not have noticed without it. It should stay.)

[PATCH v3 09/15] python: Fix .PHONY Make specifiers

[John Snow]

I missed the 'check-tox' target. Add that, but split the large .PHONY
specifier at the top into its component pieces and move them near the
targets they describe so that they're much harder to forget to update.

[PATCH v3 10/15] python: only check qemu/ subdir with flake8

[John Snow]

flake8 is a little eager to check everything it can. Limit it to
checking inside the qemu namespace directory only. Update setup.cfg now
that the exclude patterns are no longer necessary.

[PATCH v3 11/15] python: add 'make check-dev' invocation

[John Snow]

This is a *third* way to run the Python tests. Unlike the first two
(check-pipenv, check-tox), this version does not require any specific
interpreter version -- making it a lot easier to tell people to run it
as a quick smoketest prior to submission to GitLab CI.

Summary:

  Checked via GitLab CI:
    - check-pipenv: tests our oldest python & dependencies
    - check-tox: tests newest dependencies on all non-EOL python versions
  Executed only incidentally:
    - check-dev: tests newest dependencies on whichever python version

('make check' does not set up any environment at all, it just runs the
tests in your current environment. All four invocations perform the
exact same tests, just in different execution environments.)

[PATCH v3 14/15] python: remove auto-generated pyproject.toml file

[John Snow]

For reasons that at-present escape me, pipenv insists on creating a stub
pyproject.toml file. This file is a nuisance, because its mere presence
changes the behavior of various tools.

For instance, this stub file will cause "pip install --user -e ." to
fail in spectacular fashion with misleading errors. "pip install -e ."
works okay, but for some reason pip does not support editable installs
to the user directory when using PEP517.

References:
  https://github.com/pypa/pip/pull/9990
  https://github.com/pypa/pip/issues/7953

As outlined in ea1213b7ccc, it is still too early for us to consider
moving to a PEP-517 exclusive package. We must support older
distributions, so squash the annoyance for now. (Python 3.6 shipped Dec
2016, PEP517 support showed up in pip sometime in 2019 or so.)

Add 'pyproject.toml' to the 'make clean' target, and also delete it
after every pipenv invocation issued by the Makefile.

[PATCH v3 15/15] python: Fix broken ReST docstrings

[John Snow]

This patch *doesn't* update all of the docstring standards across the
QEMU package directory to make our docstring usage consistent. It
*doesn't* fix the formatting to make it look pretty or reasonable in
generated output. It *does* fix a few small instances where Sphinx would
emit a build warning because of malformed ReST -- If we built our Python
docs with Sphinx.

Signed-off-by: John Snow <jsnow@redhat.com>

You'll have to take my word for it for now, or, to test that (ugly
though it may be) a theoretical Sphinx build would produce no build
errors:

> cd ~/src/qemu/python
> sphinx-apidoc --separate --private --no-toc --module-first \
    --implicit-namespaces --full --ext-intersphinx --ext-coverage \
    --ext-viewcode qemu/ -o docs/
> sed -i '1s|^|import os; import sys; sys.path.insert(0, os.path.abspath("../"))\n|' docs/conf.py
> make -C docs html
> rm -rf docs/

I am preparing to add Sphinx, but need to fix these annoyances first so
that regressions are easy to spot as fixes are applied across the
tree. I plan to use my forthcoming Asynchronous QMP series as a test
pilot for documenting our docstring standards. Assuming it goes well, I
will update the docstrings elsewhere in this package at that time.
