Add "make venv" to create the pipenv-managed virtual environment that contains our explicitly pinned dependencies. Add "make check" to run the python linters [in the host execution environment]. Add "make venv-check" which combines the above two: create/update the venv, then run the linters in that explicitly managed environment. Add "make develop" which canonizes the runes needed to get both the linting pre-requisites (the "[devel]" part), and the editable live-install (the "-e" part) of these python libraries. make clean: delete miscellaneous python packaging output possibly created by pipenv, pip, or other python packaging utilities make distclean: delete the above, the .venv, and the editable "qemu" package forwarder (qemu.egg-info) if there is one.

QEMU Python Tooling
|
|
===================
|
|
|
|
This directory houses Python tooling used by the QEMU project to build,
|
|
configure, and test QEMU. It is organized by namespace (``qemu``), and
|
|
then by package (e.g. ``qemu/machine``, ``qemu/qmp``, etc).
|
|
|
|
``setup.py`` is used by ``pip`` to install this tooling to the current
|
|
environment. ``setup.cfg`` provides the packaging configuration used by
|
|
``setup.py`` in a setuptools specific format. You will generally invoke
|
|
it by doing one of the following:
|
|
|
|
1. ``pip3 install .`` will install these packages to your current
|
|
environment. If you are inside a virtual environment, they will
|
|
install there. If you are not, it will attempt to install to the
|
|
global environment, which is **not recommended**.
|
|
|
|
2. ``pip3 install --user .`` will install these packages to your user's
|
|
local python packages. If you are inside of a virtual environment,
|
|
this will fail; you likely want the first invocation above.
|
|
|
|
If you append the ``-e`` argument, pip will install in "editable" mode;
|
|
which installs a version of the package that installs a forwarder
|
|
pointing to these files, such that the package always reflects the
|
|
latest version in your git tree.
|
|
|
|
Installing ".[devel]" instead of "." will additionally pull in required
|
|
packages for testing this package. They are not runtime requirements,
|
|
and are not needed to simply use these libraries.
|
|
|
|
Running ``make develop`` will pull in all testing dependencies and
|
|
install QEMU in editable mode to the current environment.

|
|
- ``avocado.cfg`` Configuration for the Avocado test-runner.
|
|
Used by ``make check`` et al.
|
|
- ``Makefile`` provides some common testing/installation invocations.
|
|
Try ``make help`` to see available targets.
|
|
- ``MANIFEST.in`` is read by python setuptools, it specifies additional files
|
|
that should be included by a source distribution.
|
|
- ``PACKAGE.rst`` is used as the README file that is visible on PyPI.org.
|
|
- ``Pipfile`` is used by Pipenv to generate ``Pipfile.lock``.
|
|
- ``Pipfile.lock`` is a set of pinned package dependencies that this package
|
|
is tested under in our CI suite. It is used by ``make venv-check``.
|
|
- ``README.rst`` you are here!
|
|
- ``VERSION`` contains the PEP-440 compliant version used to describe
|
|
this package; it is referenced by ``setup.cfg``.
|
|
- ``setup.cfg`` houses setuptools package configuration.
|
|
