Reporting Bugs -------------- Bugs should be reported to https://github.com/aragilar/pytest-mpi. Please include what version of Python this occurs on, as well as which operating system. Information about your h5py and HDF5 configuration is also helpful. Patches and Pull Requests ------------------------- The main repository is https://github.com/aragilar/pytest-mpi, please make pull requests against that repository, and the branch that pull requests should be made on is master (backporting fixes will be done separately if necessary). Running the tests ----------------- pytest-mpi uses tox_ to run its tests. See https://tox.readthedocs.io/en/latest/ for more information about tox, but the simplest method is to run:: tox in the top level of the git repository. .. note:: If you want to run pytest directly, remember to include ``-p pytester``, as pytester needs to be manually activated. .. _tox: https://tox.readthedocs.io/en/latest/ Making a release ---------------- Current minimal working method (this doesn't produce a release commit, deal with DOIs needing to be preregistered, not automated, not signed etc.): #. Checkout the latest commit on the ``master`` branch on the main repository locally. Ensure the work directory is clean (``git purge``/``git clean -xfd``). #. Tag this commit with an annotated tag, with the format being ``v*.*.*`` (``git tag -a v*.*.*``; I should sign these...). The tag should mention the changes in this release. #. Push tag to github. #. Create a release on github using the web interface, copying the content of the tag. #. Build sdist and wheel (``python setup.py sdist bdist_wheel``), and upload to PyPI (``twine upload dist/*``). pytest-mpi-0.6/docs/fixtures.rst000066400000000000000000000002221416616756300170400ustar00rootroot00000000000000Fixtures ======== .. autofunction:: pytest_mpi.mpi_file_name .. autofunction:: pytest_mpi.mpi_tmp_path .. autofunction:: pytest_mpi.mpi_tmpdir pytest-mpi-0.6/docs/index.rst000066400000000000000000000017421416616756300163060ustar00rootroot00000000000000.. pytest-mpi documentation master file, created by sphinx-quickstart on Wed Jun 26 22:34:19 2019.

For example: .. code-block:: python import pytest @pytest.mark.mpi(minsize=4) def test_mpi_feature(): ... .. py:function:: pytest.mark.mpi_skip Mark that this test should be skipped when run under MPI. .. py:function:: pytest.mark.mpi_xfail Mark that this test should be xfailed when run under MPI. pytest-mpi-0.6/docs/usage.rst000066400000000000000000000023441416616756300163020ustar00rootroot00000000000000Usage ===== The important thing to remember is that `pytest-mpi` assists with running tests when `pytest` is run under MPI, rather than launching `pytest` under MPI. To actually run the tests under MPI, you will want to run something like:: $ mpirun -n 2 python -m pytest --with-mpi Note that by default the MPI tests are not run—this makes it easy to run the non-MPI parts of a test suite without having to worry about installing MPI and mpi4py. An simple test using the `mpi` marker managed by `pytest-mpi` is: .. code-block:: python import pytest @pytest.mark.mpi def test_size(): from mpi4py import MPI comm = MPI.COMM_WORLD assert comm.size > 0 This test will be automatically be skipped unless `--with-mpi` is used. We can also specify a minimum number of processes required to run the test: .. code-block:: python import pytest @pytest.mark.mpi(min_size=2) def test_size(): from mpi4py import MPI comm = MPI.COMM_WORLD assert comm.size >= 2 There are also `mpi_skip`, for when a test should not be run under MPI (e.g. it causes a lockup or segmentation fault), and `mpi_xfail`, for when a test should succeed when run normally, but fail when run under MPI. pytest-mpi-0.6/known_broken_constraints.txt000066400000000000000000000000161416616756300213720ustar00rootroot00000000000000pytest!=5.3.0 pytest-mpi-0.6/old_pytest.txt000066400000000000000000000000111416616756300164300ustar00rootroot00000000000000pytest<6 pytest-mpi-0.6/pylintrc000066400000000000000000000221421416616756300153010ustar00rootroot00000000000000[MASTER] # Specify a configuration file. #rcfile= # Python code to execute, usually for sys.path manipulation such as # pygtk.require(). #init-hook= # Add files or directories to the blacklist.

The Versioneer ============== * like a rocketeer, but for versions! * https://github.com/python-versioneer/python-versioneer * Brian Warner * License: Public Domain * Compatible with: Python 3.6, 3.7, 3.8, 3.9 and pypy3 * [![Latest Version][pypi-image]][pypi-url] * [![Build Status][travis-image]][travis-url] This is a tool for managing a recorded version number in distutils-based python projects. The goal is to remove the tedious and error-prone "update the embedded version string" step from your release process. Making a new release should be as easy as recording a new tag in your version-control system, and maybe making new tarballs. ## Quick Install * `pip install versioneer` to somewhere in your $PATH * add a `[versioneer]` section to your setup.cfg (see [Install](INSTALL.md)) * run `versioneer install` in your source tree, commit the results * Verify version information with `python setup.py version` ## Version Identifiers Source trees come from a variety of places: * a version-control system checkout (mostly used by developers) * a nightly tarball, produced by build automation * a snapshot tarball, produced by a web-based VCS browser, like github's "tarball from tag" feature * a release tarball, produced by "setup.py sdist", distributed through PyPI Within each source tree, the version identifier (either a string or a number, this tool is format-agnostic) can come from a variety of places: * ask the VCS tool itself, e.g. "git describe" (for checkouts), which knows about recent "tags" and an absolute revision-id * the name of the directory into which the tarball was unpacked * an expanded VCS keyword ($Id$, etc) * a `_version.py` created by some earlier build step For released software, the version identifier is closely related to a VCS tag. Some projects use tag names that include more than just the version string (e.g. "myproject-1.2" instead of just "1.2"), in which case the tool needs to strip the tag prefix to extract the version identifier. For unreleased software (between tags), the version identifier should provide enough information to help developers recreate the same tree, while also giving them an idea of roughly how old the tree is (after version 1.2, before version 1.3). Many VCS systems can report a description that captures this, for example `git describe --tags --dirty --always` reports things like "0.7-1-g574ab98-dirty" to indicate that the checkout is one revision past the 0.7 tag, has a unique revision id of "574ab98", and is "dirty" (it has uncommitted changes). The version identifier is used for multiple purposes: * to allow the module to self-identify its version: `myproject.__version__` * to choose a name and prefix for a 'setup.py sdist' tarball ## Theory of Operation Versioneer works by adding a special `_version.py` file into your source tree, where your `__init__.py` can import it. This `_version.py` knows how to dynamically ask the VCS tool for version information at import time. `_version.py` also contains `$Revision$` markers, and the installation process marks `_version.py` to have this marker rewritten with a tag name during the `git archive` command. As a result, generated tarballs will contain enough information to get the proper version. To allow `setup.py` to compute a version too, a `versioneer.py` is added to the top level of your source tree, next to `setup.py` and the `setup.cfg` that configures it. This overrides several distutils/setuptools commands to compute the version when invoked, and changes `setup.py build` and `setup.py sdist` to replace `_version.py` with a small static file that contains just the generated version data. ## Installation See [INSTALL.md](./INSTALL.md) for detailed installation instructions. ## Version-String Flavors Code which uses Versioneer can learn about its version string at runtime by importing `_version` from your main `__init__.py` file and running the `get_versions()` function. From the "outside" (e.g. in `setup.py`), you can import the top-level `versioneer.py` and run `get_versions()`. Both functions return a dictionary with different flavors of version information: * `['version']`: A condensed version string, rendered using the selected style. This is the most commonly used value for the project's version string. The default "pep440" style yields strings like `0.11`, `0.11+2.g1076c97`, or `0.11+2.g1076c97.dirty`. See the "Styles" section below for alternative styles. * `['full-revisionid']`: detailed revision identifier. For Git, this is the full SHA1 commit id, e.g. "1076c978a8d3cfc70f408fe5974aa6c092c949ac". * `['date']`: Date and time of the latest `HEAD` commit. For Git, it is the commit date in ISO 8601 format. This will be None if the date is not available. * `['dirty']`: a boolean, True if the tree has uncommitted changes. Note that this is only accurate if run in a VCS checkout, otherwise it is likely to be False or None * `['error']`: if the version string could not be computed, this will be set to a string describing the problem, otherwise it will be None. It may be useful to throw an exception in setup.py if this is set, to avoid e.g. creating tarballs with a version string of "unknown". Some variants are more useful than others. Including `full-revisionid` in a bug report should allow developers to reconstruct the exact code being tested (or indicate the presence of local changes that should be shared with the developers). `version` is suitable for display in an "about" box or a CLI `--version` output: it can be easily compared against release notes and lists of bugs fixed in various releases. The installer adds the following text to your `__init__.py` to place a basic version in `YOURPROJECT.__version__`: from ._version import get_versions __version__ = get_versions()['version'] del get_versions ## Styles The setup.cfg `style=` configuration controls how the VCS information is rendered into a version string. The default style, "pep440", produces a PEP440-compliant string, equal to the un-prefixed tag name for actual releases, and containing an additional "local version" section with more detail for in-between builds. For Git, this is TAG[+DISTANCE.gHEX[.dirty]] , using information from `git describe --tags --dirty --always`. For example "0.11+2.g1076c97.dirty" indicates that the tree is like the "1076c97" commit but has uncommitted changes (".dirty"), and that this commit is two revisions ("+2") beyond the "0.11" tag. For released software (exactly equal to a known tag), the identifier will only contain the stripped tag, e.g. "0.11". Other styles are available. See [details.md](details.md) in the Versioneer source tree for descriptions. ## Debugging Versioneer tries to avoid fatal errors: if something goes wrong, it will tend to return a version of "0+unknown". To investigate the problem, run `setup.py version`, which will run the version-lookup code in a verbose mode, and will display the full contents of `get_versions()` (including the `error` string, which may help identify what went wrong). ## Known Limitations Some situations are known to cause problems for Versioneer. This details the most significant ones. More can be found on Github [issues page](https://github.com/python-versioneer/python-versioneer/issues). ### Subprojects Versioneer has limited support for source trees in which `setup.py` is not in the root directory (e.g. `setup.py` and `.git/` are *not* siblings). The are two common reasons why `setup.py` might not be in the root: * Source trees which contain multiple subprojects, such as [Buildbot](https://github.com/buildbot/buildbot), which contains both "master" and "slave" subprojects, each with their own `setup.py`, `setup.cfg`, and `tox.ini`. Projects like these produce multiple PyPI distributions (and upload multiple independently-installable tarballs). * Source trees whose main purpose is to contain a C library, but which also provide bindings to Python (and perhaps other languages) in subdirectories. Versioneer will look for `.git` in parent directories, and most operations should get the right version string. However `pip` and `setuptools` have bugs and implementation details which frequently cause `pip install .` from a subproject directory to fail to find a correct version string (so it usually defaults to `0+unknown`). `pip install --editable .` should work correctly. `setup.py install` might work too. Pip-8.1.1 is known to have this problem, but hopefully it will get fixed in some later version. [Bug #38](https://github.com/python-versioneer/python-versioneer/issues/38) is tracking this issue. The discussion in [PR #61](https://github.com/python-versioneer/python-versioneer/pull/61) describes the issue from the Versioneer side in more detail. [pip PR#3176](https://github.com/pypa/pip/pull/3176) and [pip PR#3615](https://github.com/pypa/pip/pull/3615) contain work to improve pip to let Versioneer work correctly. Versioneer-0.16 and earlier only looked for a `.git` directory next to the `setup.cfg`, so subprojects were completely unsupported with those releases. ### Editable installs with setuptools <= 18.5 `setup.py develop` and `pip install --editable .` allow you to install a project into a virtualenv once, then continue editing the source code (and test) without re-installing after every change. "Entry-point scripts" (`setup(entry_points={"console_scripts": ..})`) are a convenient way to specify executable scripts that should be installed along with the python package. These both work as expected when using modern setuptools. When using setuptools-18.5 or earlier, however, certain operations will cause `pkg_resources.DistributionNotFound` errors when running the entrypoint script, which must be resolved by re-installing the package. This happens when the install happens with one version, then the egg_info data is regenerated while a different version is checked out. Many setup.py commands cause egg_info to be rebuilt (including `sdist`, `wheel`, and installing into a different virtualenv), so this can be surprising. [Bug #83](https://github.com/python-versioneer/python-versioneer/issues/83) describes this one, but upgrading to a newer version of setuptools should probably resolve it. ## Updating Versioneer To upgrade your project to a new release of Versioneer, do the following: * install the new Versioneer (`pip install -U versioneer` or equivalent) * edit `setup.cfg`, if necessary, to include any new configuration settings indicated by the release notes. See [UPGRADING](./UPGRADING.md) for details. * re-run `versioneer install` in your source tree, to replace `SRC/_version.py` * commit any changed files ## Future Directions This tool is designed to make it easily extended to other version-control systems: all VCS-specific components are in separate directories like src/git/ . The top-level `versioneer.py` script is assembled from these components by running make-versioneer.py . In the future, make-versioneer.py will take a VCS name as an argument, and will construct a version of `versioneer.py` that is specific to the given VCS. It might also take the configuration arguments that are currently provided manually during installation by editing setup.py . Alternatively, it might go the other direction and include code from all supported VCS systems, reducing the number of intermediate scripts. ## Similar projects * [setuptools_scm](https://github.com/pypa/setuptools_scm/) - a non-vendored build-time dependency * [minver](https://github.com/jbweston/miniver) - a lightweight reimplementation of versioneer * [versioningit](https://github.com/jwodder/versioningit) - a PEP 518-based setuptools plugin ## License To make Versioneer easier to embed, all its code is dedicated to the public domain.
