Hacking on :mod:`zope.event` ============================ Getting the Code ----------------- The main repository for :mod:`zope.event` is in the Zope Subversion repository: http://svn.zope.org/zope.event You can get a read-only Subversion checkout from there: .. code-block:: sh $ svn checkout svn://svn.zope.org/repos/main/zope.event/trunk zope.event The project also mirrors the trunk from the Subversion repository as a Bazaar branch on Launchpad: https://code.launchpad.net/zope.event You can branch the trunk from there using Bazaar: .. code-block:: sh $ bzr branch lp:zope.event Running the tests in a ``virtualenv`` ------------------------------------- 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.event Next, get this package registered as a "development egg" in the environment: .. code-block:: sh $ /tmp/hack-zope.event/bin/python setup.py develop Finally, run the tests using the build-in ``setuptools`` testrunner: .. code-block:: sh $ /tmp/hack-zope.event/bin/python setup.py test running test ... test_empty (zope.event.tests.Test_notify) ... ok test_not_empty (zope.event.tests.Test_notify) ... ok ---------------------------------------------------------------------- Ran 2 tests in 0.000s OK If you have the :mod:`nose` package installed in the virtualenv, you can use its testrunner too: .. code-block:: sh $ /tmp/hack-zope.event/bin/easy_install nose ... $ /tmp/hack-zope.event/bin/python setup.py nosetests running nosetests ... ---------------------------------------------------------------------- Ran 3 tests in 0.011s OK or: .. code-block:: sh $ /tmp/hack-zope.event/bin/nosetests ... ---------------------------------------------------------------------- Ran 3 tests in 0.011s 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.event/bin/easy_install nose coverage ... $ /tmp/hack-zope.event/bin/python setup.py nosetests \ --with coverage --cover-package=zope.event running nosetests ... Name Stmts Exec Cover Missing ------------------------------------------ zope.event 5 5 100% ---------------------------------------------------------------------- Ran 3 tests in 0.019s OK Building the documentation in a ``virtualenv`` ---------------------------------------------- :mod:`zope.event` 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.event/bin/easy_install Sphinx ... $ cd docs $ PATH=/tmp/hack-zope.event/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.event/bin:$PATH make doctest sphinx-build -b doctest -d _build/doctrees . _build/doctest ... running tests... Document: index --------------- 1 items passed all tests: 17 tests in default 17 tests in 1 items. 17 passed and 0 failed. Test passed. Doctest summary =============== 17 tests 0 failures in tests 0 failures in setup code build succeeded. Testing of doctests in the sources finished, look at the \ results in _build/doctest/output.txt. Running the tests using :mod:`zc.buildout` ------------------------------------------- :mod:`zope.event` ships with its own :file:`buildout.cfg` file and :file:`bootstrap.py` for setting up a development buildout: .. code-block:: sh $ /path/to/python2.6 bootstrap.py ... Generated script '.../bin/buildout' $ bin/buildout Develop: '/home/tseaver/projects/Zope/BTK/event/.' ... Generated script '.../bin/sphinx-quickstart'. Generated script '.../bin/sphinx-build'. 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 2 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. Building the documentation using :mod:`zc.buildout` --------------------------------------------------- The :mod:`zope.event` buildout installs the Sphinx scripts required to build the documentation, including testing its code snippets: .. code-block:: sh $ cd docs $ PATH=../bin:$PATH make doctest html .../bin/sphinx-build -b doctest -d .../docs/_build/doctrees .../docs .../docs/_build/doctest running tests... Document: index --------------- 1 items passed all tests: 17 tests in default 17 tests in 1 items. 17 passed and 0 failed. Test passed. Doctest summary =============== 17 tests 0 failures in tests 0 failures in setup code build succeeded. Testing of doctests in the sources finished, look at the results in .../docs/_build/doctest/output.txt. .../bin/sphinx-build -b html -d .../docs/_build/doctrees .../docs .../docs/_build/html ... build succeeded. Build finished. The HTML pages are in .../docs/_build/html. Running Tests on Multiple Python Versions via :mod:`tox` -------------------------------------------------------- `tox <http://tox.testrun.org/latest/>`_ 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.event` configures the following :mod:`tox` environments via its ``tox.ini`` file: - The ``py26`` environment builds a ``virtualenv`` with ``python2.6``, installs :mod:`zope.event`, and runs the tests via ``python setup.py test -q``. - The ``py27`` environment builds a ``virtualenv`` with ``python2.7``, installs :mod:`zope.event`, and runs the tests via ``python setup.py test -q``. - The ``py32`` environment builds a ``virtualenv`` with ``python3.2``, installs :mod:`zope.event` and dependencies, and runs the tests via ``python setup.py test -q``. - The ``pypy`` environment builds a ``virtualenv`` with ``pypy``, installs :mod:`zope.event`, and runs the tests via ``python setup.py test -q``. - The ``coverage`` environment builds a ``virtualenv`` with ``python2.6``, installs :mod:`zope.event`, installs :mod:`nose` and :mod:`coverage`, and runs ``nosetests`` with statement coverage. - The ``docs`` environment builds a virtualenv with ``python2.6``, installs :mod:`zope.event`, 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: .../zope.interface/setup.py py26 sdist-reinst: .../zope.interface/.tox/dist/zope.interface-4.0.2dev.zip py26 runtests: commands[0] ... ---------------------------------------------------------------------- Ran 2 tests in 0.000s 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.interface/setup.py py26 sdist-reinst: .../zope.interface/.tox/dist/zope.interface-4.0.2dev.zip py26 runtests: commands[0] ... Doctest summary =============== 17 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 pypy: commands succeeded coverage: commands succeeded docs: commands succeeded congratulations :) Submitting a Bug Report ----------------------- :mod:`zope.event` tracks its bugs on Launchpad: https://bugs.launchpad.net/zope.event 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 you got a read-only checkout from the Subversion repository, and you have made a change you would like to share, the best route is to let Subversion help you make a patch file: .. code-block:: sh $ svn diff > zope.event-cool_feature.patch You can then upload that patch file as an attachment to a Launchpad bug report. 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:~tseaver/zope.event/cool_feature After pushing your branch, you can link it to a bug report on Launchpad, or request that the maintainers merge your branch using the Launchpad "merge request" feature.
