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``. 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 want the first invocation above.
If you append the ``--editable`` or ``-e`` argument to either invocation
above, pip will install in "editable" mode. This installs the package as
a forwarder ("qemu.egg-link") that points to the source tree. In so
doing, the installed package always reflects the latest version in your
source 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.
(It is a shortcut for ``pip3 install -e .[devel]``.)
See `Installing packages using pip and virtual environments
<https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/>`_
for more information.
Files in this directory
-----------------------
- ``qemu/`` Python 'qemu' namespace package source directory.
- ``tests/`` Python package tests directory.
- ``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.
- ``setup.py`` is the setuptools installer used by pip; See above.
