Ping O:-) Looking for feedback from at least Cleber and Eduardo before I barge ahead and send a PR to include this on master. Additional packaging and versioning feedback from Dan would be nice. (I know we have a very busy two weeks here; I will continue pinging, but I have every intention of merging this prior to 5.2.) --js On 10/20/20 3:35 PM, John Snow wrote: > Based-on: https://gitlab.com/jsnow/qemu/-/tree/python > > This series factors the python/qemu directory as an installable > package.

Too pythonic for me, so I'll defer that to Python experts. It would be nice to have this in 5.2 indeed... Regards, Phil.
Based-on: https://gitlab.com/jsnow/qemu/-/tree/python This series factors the python/qemu directory as an installable package. It does not yet actually change the mechanics of how any other python source in the tree actually consumes it (yet), beyond the import path. The point of this series is primarily to formalize our dependencies on mypy, flake8, isort, and pylint alongside versions that are known to work. It also adds explicitly pinned versions of these dependencies that should behave in a repeatable and known way for developers and CI environments both. With the python tooling as a proper package, you can install this package in editable or production mode to a virtual environment, your local user environment, or your system packages. The primary benefit of this is to gain access to QMP tooling regardless of CWD, without needing to battle sys.path. For example: when developing, you may go to qemu/python/ and invoke `pipenv shell` to activate a virtual environment that contains the qemu packages. This package will always reflect the current version of the source files in the tree. When you are finished, you can simply exit the shell to remove these packages from your python environment. When not developing, you could install a version of this package to your environment outright to gain access to the QMP and QEMUMachine classes for lightweight scripting and testing by using pip: "pip install [--user] ." Finally, this package is formatted in such a way that it COULD be uploaded to https://pypi.org/project/qemu and installed independently of qemu.git with `pip install qemu`, but that button remains unpushed. TESTING THIS SERIES: CD to qemu/python first, and then: 1. Try "pipenv shell" to get a venv with the package installed to it in editable mode. Ctrl+d exits this venv shell. While in this shell, any python script that uses "from qemu.[qmp|machine] import ..." should work correctly regardless of your CWD. 2. Try "pipenv sync --dev" to create/update the venv with the development packages without actually entering the venv. This should install isort, mypy, flake8 and pylint to the venv. 3. After the above sync, try "pipenv shell" again, and from the python project root, try any of the following: - pylint qemu - flake8 qemu - isort -c qemu - mypy qemu 4. Leave any venv you are in, and from the project root, try the following commands: - pipenv run pylint qemu - pipenv run flake8 qemu - pipenv run isort -c qemu - pipenv run mypy qemu V3: - Changed "qemu.core" to "qemu.qmp" and "qemu.machine", Partly to accommodate forthcoming work which would benefit from a separate qemu.qmp namespace. - Changed the initial version from 5.2.0a1 to 0.5.2.0a1, to allow for more rapid development while we smooth out the initial kinks. - 001: Renamed patch title; differences implement the new names. - 002: Readme changes for above. - 003: Version change. - 004: New readme for the new qmp directory. - 006: A few more import exceptions for pylint, hopefully temporary. - 009: Updated flake8 config comment to match qapi's - 012: Added namespace_package configuration value 001/15:[down] 'python: create qemu packages' 002/15:[0009] [FC] 'python: add qemu package installer' 003/15:[0002] [FC] 'python: add VERSION file' 004/15:[0015] [FC] 'python: add directory structure README.rst files' 005/15:[----] [--] 'python: Add pipenv support' 006/15:[down] 'python: add pylint import exceptions' 007/15:[----] [--] 'python: move pylintrc into setup.cfg' 008/15:[----] [--] 'python: add pylint to pipenv' 009/15:[0002] [FC] 'python: move flake8 config to setup.cfg' 010/15:[----] [--] 'python: Add flake8 to pipenv' 011/15:[----] [-C] 'python: move mypy.ini into setup.cfg' 012/15:[0001] [FC] 'python: add mypy to pipenv' 013/15:[----] [--] 'python: move .isort.cfg into setup.cfg' 014/15:[----] [--] 'python/qemu: add isort to pipenv' 015/15:[----] [--] 'python/qemu: add qemu package itself to pipenv' John Snow (15): python: create qemu packages python: add qemu package installer python: add VERSION file python: add directory structure README.rst files python: Add pipenv support python: add pylint import exceptions python: move pylintrc into setup.cfg python: add pylint to pipenv python: move flake8 config to setup.cfg python: Add flake8 to pipenv python: move mypy.ini into setup.cfg python: add mypy to pipenv python: move .isort.cfg into setup.cfg python/qemu: add isort to pipenv python/qemu: add qemu package itself to pipenv python/PACKAGE.rst | 26 +++ python/README.rst | 27 +++ python/qemu/README.rst | 8 + python/qemu/machine/README.rst | 9 + python/qemu/qmp/README.rst | 9 + python/Pipfile | 16 ++ python/Pipfile.lock | 207 ++++++++++++++++++++ python/VERSION | 1 + python/mypy.ini | 4 - python/qemu/.flake8 | 2 - python/qemu/.isort.cfg | 7 - python/qemu/__init__.py | 11 -- python/qemu/machine/__init__.py | 44 +++++ python/qemu/{ => machine}/accel.py | 0 python/qemu/{ => machine}/console_socket.py | 0 python/qemu/{ => machine}/machine.py | 16 +- python/qemu/{ => machine}/qtest.py | 3 +- python/qemu/{qmp.py => qmp/__init__.py} | 12 +- python/{qemu/pylintrc => setup.cfg} | 67 ++++--- python/setup.py | 23 +++ tests/acceptance/boot_linux.py | 3 +- tests/qemu-iotests/297 | 2 +- tests/qemu-iotests/300 | 4 +- tests/qemu-iotests/iotests.py | 2 +- tests/vm/basevm.py | 3 +- 25 files changed, 437 insertions(+), 69 deletions(-) create mode 100644 python/PACKAGE.rst create mode 100644 python/README.rst create mode 100644 python/qemu/README.rst create mode 100644 python/qemu/machine/README.rst create mode 100644 python/qemu/qmp/README.rst create mode 100644 python/Pipfile create mode 100644 python/Pipfile.lock create mode 100644 python/VERSION delete mode 100644 python/mypy.ini delete mode 100644 python/qemu/.flake8 delete mode 100644 python/qemu/.isort.cfg delete mode 100644 python/qemu/__init__.py create mode 100644 python/qemu/machine/__init__.py rename python/qemu/{ => machine}/accel.py (100%) rename python/qemu/{ => machine}/console_socket.py (100%) rename python/qemu/{ => machine}/machine.py (98%) rename python/qemu/{ => machine}/qtest.py (98%) rename python/qemu/{qmp.py => qmp/__init__.py} (96%) rename python/{qemu/pylintrc => setup.cfg} (50%) mode change 100644 => 100755 create mode 100755 python/setup.py -- 2.26.2
