Hacking on :mod:`zope.location` =============================== Getting the Code ################ The main repository for :mod:`zope.location` is in the Zope Foundation Github repository: https://github.com/zopefoundation/zope.location You can get a read-only checkout from there: .. code-block:: sh $ git clone https://github.com/zopefoundation/zope.location.git or fork it and get a writeable checkout of your fork: .. code-block:: sh $ git clone git@github.com/jrandom/zope.location.git The project also mirrors the trunk from the Github repository as a Bazaar branch on Launchpad: https://code.launchpad.net/zope.location You can branch the trunk from there using Bazaar: .. code-block:: sh $ bzr branch lp:zope.location Working in a ``virtualenv`` ########################### Installing ---------- If you use the ``virtualenv`` package to create lightweight Python development environments, you can run the tests using nothing more than the ``python`` binary in a virtualenv. First, create a scratch environment: .. code-block:: sh $ /path/to/virtualenv --no-site-packages /tmp/hack-zope.location Next, get this package registered as a "development egg" in the environment: .. code-block:: sh $ /tmp/hack-zope.location/bin/python setup.py develop Running the tests ----------------- Then, you canrun the tests using the build-in ``setuptools`` testrunner: .. code-block:: sh $ /tmp/hack-zope.location/bin/python setup.py test -q ............................................................................... ---------------------------------------------------------------------- Ran 83 tests in 0.037s OK If you have the :mod:`nose` package installed in the virtualenv, you can use its testrunner too: .. code-block:: sh $ /tmp/hack-zope.location/bin/nosetests ....................................................................................... ---------------------------------------------------------------------- Ran 87 tests in 0.037s OK If you have the :mod:`coverage` pacakge installed in the virtualenv, you can see how well the tests cover the code: .. code-block:: sh $ /tmp/hack-zope.location/bin/easy_install nose coverage ... $ /tmp/hack-zope.location/bin/nosetests --with coverage ....................................................................................... Name Stmts Miss Cover Missing -------------------------------------------------------- zope.location 5 0 100% zope.location._compat 2 0 100% zope.location.interfaces 23 0 100% zope.location.location 61 0 100% zope.location.pickling 14 0 100% zope.location.traversing 80 0 100% -------------------------------------------------------- TOTAL 185 0 100% ---------------------------------------------------------------------- Ran 87 tests in 0.315s OK Building the documentation -------------------------- :mod:`zope.location` uses the nifty :mod:`Sphinx` documentation system for building its docs. Using the same virtualenv you set up to run the tests, you can build the docs: .. code-block:: sh $ /tmp/hack-zope.location/bin/easy_install \ Sphinx repoze.sphinx.autoitnerface zope.component ... $ cd docs $ PATH=/tmp/hack-zope.location/bin:$PATH make html sphinx-build -b html -d _build/doctrees . _build/html ... build succeeded. Build finished. The HTML pages are in _build/html. You can also test the code snippets in the documentation: .. code-block:: sh $ PATH=/tmp/hack-zope.location/bin:$PATH make doctest sphinx-build -b doctest -d _build/doctrees . _build/doctest ... running tests... ... Doctest summary =============== 187 tests 0 failures in tests 0 failures in setup code 0 failures in cleanup code build succeeded. Testing of doctests in the sources finished, look at the results in _build/doctest/output.txt. Using :mod:`zc.buildout` ######################## Setting up the buildout ----------------------- :mod:`zope.location` ships with its own :file:`buildout.cfg` file and :file:`bootstrap.py` for setting up a development buildout: .. code-block:: sh $ /path/to/python2.7 bootstrap.py ... Generated script '.../bin/buildout' $ bin/buildout Develop: '/home/jrandom/projects/Zope/zope.location/.' ... Got coverage 3.7.1 Running the tests ----------------- You can now run the tests: .. code-block:: sh $ bin/test --all Running zope.testing.testrunner.layer.UnitTests tests: Set up zope.testing.testrunner.layer.UnitTests in 0.000 seconds. Ran 79 tests with 0 failures and 0 errors in 0.000 seconds. Tearing down left over layers: Tear down zope.testing.testrunner.layer.UnitTests in 0.000 seconds. Using :mod:`tox` ################ Running Tests on Multiple Python Versions ----------------------------------------- `tox `_ is a Python-based test automation tool designed to run tests against multiple Python versions. It creates a ``virtualenv`` for each configured version, installs the current package and configured dependencies into each ``virtualenv``, and then runs the configured commands. :mod:`zope.location` configures the following :mod:`tox` environments via its ``tox.ini`` file: - The ``py26``, ``py27``, ``py33``, ``py34``, and ``pypy`` environments builds a ``virtualenv`` with ``pypy``, installs :mod:`zope.location` and dependencies, and runs the tests via ``python setup.py test -q``. - The ``coverage`` environment builds a ``virtualenv`` with ``python2.6``, installs :mod:`zope.location`, installs :mod:`nose` and :mod:`coverage`, and runs ``nosetests`` with statement coverage. - The ``docs`` environment builds a virtualenv with ``python2.6``, installs :mod:`zope.location`, installs ``Sphinx`` and dependencies, and then builds the docs and exercises the doctest snippets. This example requires that you have a working ``python2.6`` on your path, as well as installing ``tox``: .. code-block:: sh $ tox -e py26 GLOB sdist-make: /home/jrandom/projects/Zope/Z3/zope.location/setup.py py26 create: /home/jrandom/projects/Zope/Z3/zope.location/.tox/py26 py26 installdeps: zope.configuration, zope.copy, zope.interface, zope.proxy, zope.schema py26 inst: /home/jrandom/projects/Zope/Z3/zope.location/.tox/dist/zope.location-4.0.4.dev0.zip py26 runtests: PYTHONHASHSEED='3489368878' py26 runtests: commands[0] | python setup.py test -q running test ... ................................................................................... ---------------------------------------------------------------------- Ran 83 tests in 0.066s OK ___________________________________ summary ____________________________________ py26: commands succeeded congratulations :) Running ``tox`` with no arguments runs all the configured environments, including building the docs and testing their snippets: .. code-block:: sh $ tox GLOB sdist-make: .../zope.location/setup.py py26 sdist-reinst: .../zope.location/.tox/dist/zope.location-4.0.2dev.zip ... Doctest summary =============== 187 tests 0 failures in tests 0 failures in setup code 0 failures in cleanup code build succeeded. ___________________________________ summary ____________________________________ py26: commands succeeded py27: commands succeeded py32: commands succeeded py33: commands succeeded py34: commands succeeded pypy: commands succeeded coverage: commands succeeded docs: commands succeeded congratulations :) Contributing to :mod:`zope.location` #################################### Submitting a Bug Report ----------------------- :mod:`zope.location` tracks its bugs on Github: https://github.com/zopefoundation/zope.location/issues Please submit bug reports and feature requests there. Sharing Your Changes -------------------- .. note:: Please ensure that all tests are passing before you submit your code. If possible, your submission should include new tests for new features or bug fixes, although it is possible that you may have tested your new code by updating existing tests. If have made a change you would like to share, the best route is to fork the Githb repository, check out your fork, make your changes on a branch in your fork, and push it. You can then submit a pull request from your branch: https://github.com/zopefoundation/zope.location/pulls If you branched the code from Launchpad using Bazaar, you have another option: you can "push" your branch to Launchpad: .. code-block:: sh $ bzr push lp:~jrandom/zope.location/cool_feature After pushing your branch, you can link it to a bug report on Github, or request that the maintainers merge your branch using the Launchpad "merge request" feature.
