git clone https://github.com/scikit-hep/pyhf.git
and install all necessary packages for development
python -m pip install --ignore-installed -U -e .[complete]
Then setup the Git pre-commit hook for Black by running
rev gets updated through time to track changes of different hooks,
to have pre-commit install the new version.
A function-scoped fixture called
datadir exists for a given test module
which will automatically copy files from the associated test modules data
directory into a temporary directory for the given test execution. That is, for
example, if a test was defined in
test_schema.py, then data files located
test_schema/ will be copied to a temporary directory whose path is made
available by the
datadir fixture. Therefore, one can do:
def test_patchset(datadir): data_file = open(datadir.join("test.txt")) ...
which will load the copy of
text.txt in the temporary directory. This also
works for parameterizations as this will effectively sandbox the file
pyhf tests packaging and distributing by publishing each commit to
master to TestPyPI.
In addition, installation of the latest test release from TestPyPI can be tested
by first installing
pyhf normally, to ensure all dependencies are installed
from PyPI, and then upgrading
pyhf to a dev release from TestPyPI
python -m pip install pyhf python -m pip install --upgrade --extra-index-url https://test.pypi.org/simple/ --pre pyhf
This adds TestPyPI as an additional package index to search
PyPI will still be the default package index
pip will attempt to install
from for all dependencies, but if a package has a release on TestPyPI that
is a more recent release then the package will be installed from TestPyPI instead.
Note that dev releases are considered pre-releases, so
0.1.2 is a “newer”
Publishing to PyPI and TestPyPI
is automated through the PyPA’s PyPI publish GitHub Action
pyhf Tag Creator GitHub Actions workflow.
A release can be created from any PR created by a core developer by adding a
bumpversion tag to it that corresponds to the release type:
Once the PR is tagged with the label, the GitHub Actions bot will post a comment
with information on the actions it will take once the PR is merged. When the PR
has been reviewed, approved, and merged, the Tag Creator workflow will automatically
create a new release with
bump2version and then deploy the release to PyPI.
Context Files and Archive Metadata¶
codemeta.json files have the version number
automatically updated through
bump2version, though their additional metadata
should be checked periodically by the dev team (probably every release).
codemeta.json file can be generated automatically from a PyPI install
codemetapy --no-extras pyhf > codemeta.json
author metadata will still need to be checked and revised by hand.
.zenodo.json is currently generated by hand, so it is worth using
codemeta.json as a guide to edit it.
