Contributions are welcome, and they are greatly appreciated! Every little bit helps, and credit will always be given.
You can contribute in many ways:
Report bugs at the GitHub Issues page.
If you are reporting a bug, please include:
- Your operating system name and version.
- Any details about your local setup that might be helpful in troubleshooting.
- Detailed steps to reproduce the bug.
Look through the GitHub issues for bugs. Anything tagged with "bug" and "help wanted" is open to whoever wants to implement it.
Look through the GitHub issues for features. Anything tagged with "enhancement" and "help wanted" is open to whoever wants to implement it.
CTGAN could always use more documentation, whether as part of the official CTGAN docs, in docstrings, or even on the web in blog posts, articles, and such.
The best way to send feedback is to file an issue at the GitHub Issues page.
If you are proposing a feature:
- Explain in detail how it would work.
- Keep the scope as narrow as possible, to make it easier to implement.
- Remember that this is a volunteer-driven project, and that contributions are welcome :)
Ready to contribute? Here's how to set up CTGAN for local development.
Fork the CTGAN repo on GitHub.
Clone your fork locally:
$ git clone [email protected]:your_name_here/CTGAN.git
Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:
$ mkvirtualenv CTGAN $ cd CTGAN/ $ make install-develop
Create a branch for local development:
$ git checkout -b name-of-your-bugfix-or-feature
Try to use the naming scheme of prefixing your branch with
gh-X
where X is the associated issue, such asgh-3-fix-foo-bug
. And if you are not developing on your own fork, further prefix the branch with your GitHub username, likegithubusername/gh-3-fix-foo-bug
.Now you can make your changes locally.
While hacking your changes, make sure to cover all your developments with the required unit tests, and that none of the old tests fail as a consequence of your changes. For this, make sure to run the tests suite and check the code coverage:
$ make lint # Check code styling $ make test # Run the tests $ make coverage # Get the coverage report
When you're done making changes, check that your changes pass all the styling checks and tests, including other Python supported versions, using:
$ make test-all
Make also sure to include the necessary documentation in the code as docstrings following the Google docstrings style. If you want to view how your documentation will look like when it is published, you can generate and view the docs with this command:
$ make view-docs
Commit your changes and push your branch to GitHub:
$ git add . $ git commit -m "Your detailed description of your changes." $ git push origin name-of-your-bugfix-or-feature
Submit a pull request through the GitHub website.
Before you submit a pull request, check that it meets these guidelines:
- It resolves an open GitHub Issue and contains its reference in the title or the comment. If there is no associated issue, feel free to create one.
- Whenever possible, it resolves only one issue. If your PR resolves more than one issue, try to split it in more than one pull request.
- The pull request should include unit tests that cover all the changed code
- If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the documentation in an appropriate place.
- The pull request should work for all the supported Python versions. Check the Travis Build Status page and make sure that all the checks pass.
All the Unit Tests should comply with the following requirements:
- Unit Tests should be based only in unittest and pytest modules.
- The tests that cover a module called
ctgan/path/to/a_module.py
should be implemented in a separated module calledtests/ctgan/path/to/test_a_module.py
. Note that the module name has thetest_
prefix and is located in a path similar to the one of the tested module, just inside thetests
folder. - Each method of the tested module should have at least one associated test method, and each test method should cover only one use case or scenario.
- Test case methods should start with the
test_
prefix and have descriptive names that indicate which scenario they cover. Names such astest_some_methed_input_none
,test_some_method_value_error
ortest_some_method_timeout
are right, but names liketest_some_method_1
,some_method
ortest_error
are not. - Each test should validate only what the code of the method being tested does, and not cover the behavior of any third party package or tool being used, which is assumed to work properly as far as it is being passed the right values.
- Any third party tool that may have any kind of random behavior, such as some Machine
Learning models, databases or Web APIs, will be mocked using the
mock
library, and the only thing that will be tested is that our code passes the right values to them. - Unit tests should not use anything from outside the test and the code being tested. This includes not reading or writing to any file system or database, which will be properly mocked.
To run a subset of tests:
$ python -m pytest tests.test_ctgan
$ python -m pytest -k 'foo'
The process of releasing a new version involves several steps combining both git
and
bumpversion
which, briefly:
- Merge what is in
main
branch intostable
branch. - Update the version in
setup.cfg
,ctgan/__init__.py
andHISTORY.md
files. - Create a new git tag pointing at the corresponding commit in
stable
branch. - Merge the new commit from
stable
intomain
. - Update the version in
setup.cfg
andctgan/__init__.py
to open the next development iteration.
Note
Before starting the process, make sure that HISTORY.md
has been updated with a new
entry that explains the changes that will be included in the new version.
Normally this is just a list of the Pull Requests that have been merged to main
since the last release.
Once this is done, run of the following commands:
If you are releasing a patch version:
make release
If you are releasing a minor version:
make release-minor
If you are releasing a major version:
make release-major
Sometimes it is necessary or convenient to upload a release candidate to PyPi as a pre-release, in order to make some of the new features available for testing on other projects before they are included in an actual full-blown release.
In order to perform such an action, you can execute:
make release-candidate
This will perform the following actions:
- Build and upload the current version to PyPi as a pre-release, with the format
X.Y.Z.devN
- Bump the current version to the next release candidate,
X.Y.Z.dev(N+1)
After this is done, the new pre-release can be installed by including the dev
section in the
dependency specification, either in setup.py
:
install_requires = [
...
'ctgan>=X.Y.Z.dev',
...
]
or in command line:
pip install 'ctgan>=X.Y.Z.dev'
