Details ======= This introduces a Python virtual environment that will be setup within the QEMU build directory, that will contain the exact environment that tests may require. There's one current caveat: it requires Python 3, as it's based on the venv module. This was based on some discussions and perception about standardizing on Python 3, but can easily be made to accommodate Python 2 as well.

Changes from v6: ================ * Fixed the whitespace .vs. tab mistake in the $(error) action printing the Python 3 requirements for venvs. (Wainer) * Changed the Python version check approach so that shell output with Python version is not generated any time. This requires GNU Make >= 4.2, a ~2 year old release, which seems to a safe assumption, but I couldn't find any hard information about mininum versions required for building QEMU. (Wainer) Changes from v5: ================ * Renamed tests/venv-requirements.txt to tests/requirements.txt (Caio). * Moved the Travis package dependencies (python3-pip and Python3.4-venv) to the specific job block (Philippe / Alex). Changes from v4: ================ * Added Python 3 version check and error message when running under Python 2. (Philippe) * Added notes about using Avocado from the virtual environment without previous activation. (Philippe) Ideas discussed, but not implemented: * Instructions to activate/deactivate the venv: the idea is to be use the venv as transparently as possible. * Move/rename tests/venv-requirements: the ideal, as per the first commit is to provide one venv for all Python based tests to run. * Changed the Travis package requirements (python3-pip, python3.4-venv) from the global setting to the job specific one: waiting on further feedback from'Alex Bennée. Changes from v3: ================ * Fixed typo in commit message (s/requiment/requirement/). (Eric) Changes from v2: ================ * Make the $(TESTS_VENV_DIR) target depend on the venv-requirements.txt file, and touch $(TESTS_VENV_DIR) after venv runs. With this, updates on the file are reflected on the venv. (Philippe) * Run pip with "python -m pip". It may have been installed reusing the system wide packages, and then the script may not be available on the venv. (Philippe) * Dropped Python version on Travis, and using the version supplied by the distro (3.4). (Philippe) * Added "python3.4-venv" package requirement on Travis. (Philippe) * Added variable (AVOCADO_SHOW) with logging streams to be shown while running the acceptance tests. By default it's set to none, the equivalent of the quiet mode used on previous versions. (Philippe) * On Travis, set the AVOCADO_SHOW variable to "app", so that the individual test results can be easily seen. (Philippe) Ideas discussed, but not implemented: * Run pip with "$(PYTHON) -m pip -q install ..." because it points to the system wide Python installation. (Philippe) * Drop the "--system-site-packages" flag. Waiting on another round of tests to determine if they are really the cause of some package installation problems. Changes from v1: ================ * TESTS_VENV_REQ (the path of "venv-requirements.txt") now points to the source path ($SRC_PATH instead of $BUILD_DIR) * Create the venv with "--system-site-packages", which allows the reuse of packages (and no additional downloads) in case there's a package installed system wide providing the same package and version. * Run Avocado with "python -m avocado". It may have been installed reusing the system wide packages, and then the script may not be available on the venv. * Improved documentation describing the Python 3, venv and pip requirements. * Updated avocado-framework requirement to latest released version (65.0) * (New commit) Added support for running the acceptance tests on Travis. Ideas discussed, but not implemented: * Install external packages such as python3-pip on Debian based systems, deemed too invasive on developer's systems. * Allow the use of Python 2, and consequently the "virtualenv" module.
