# Contribution guide First, thank you for contributing! We love and encourage pull requests from everyone. Please follow the guidelines: - Check the open [issues](https://git.frostfs.info/TrueCloudLab/frostfs-testcases/issues) and [pull requests](https://git.frostfs.info/TrueCloudLab/frostfs-testcases/pulls) for existing discussions. - Open an issue first, to discuss a new feature or enhancement. - Write tests, and make sure the test suite passes locally. - Open a pull request, and reference the relevant issue(s). - Make sure your commits are logically separated and have good comments explaining the details of your change. - After receiving feedback, amend your commits or add new ones as appropriate. - **Have fun!** ## Development Workflow Start by forking the `frostfs-testcases` repository, make changes in a branch and then send a pull request. We encourage pull requests to discuss code changes. Here are the steps in details: ### Set up your Git Repository Fork [FrosfFS testcases upstream](https://git.frostfs.info/TrueCloudLab/frostfs-testcases/forks) source repository to your own personal repository. Copy the URL of your fork and clone it: ```shell $ git clone <url of your fork> ``` ### Set up git remote as ``upstream`` ```sh $ cd frostfs-testcases $ git remote add upstream https://git.frostfs.info/TrueCloudLab/frostfs-testcases $ git fetch upstream ``` ### Set up development environment To setup development environment for `frosfs-testcases`, please, take the following steps: 1. Prepare virtualenv ```shell $ make venv $ source frostfs-testcases-3.10/bin/activate ``` Optionally you might want to integrate code formatters with your code editor to apply formatters to code files as you go: * isort is supported by [PyCharm](https://plugins.jetbrains.com/plugin/15434-isortconnect), [VS Code](https://cereblanco.medium.com/setup-black-and-isort-in-vscode-514804590bf9). Plugins exist for other IDEs/editors as well. * black can be integrated with multiple editors, please, instructions are available [here](https://black.readthedocs.io/en/stable/integrations/editors.html). ### Create your feature branch Before making code changes, make sure you create a separate branch for these changes. Maybe you will find it convenient to name branch in `<type>/<issue>-<changes_topic>` format. ```shell $ git checkout -b feature/123-something_awesome ``` ### Commit changes After verification, commit your changes. There is a [great post](https://chris.beams.io/posts/git-commit/) on how to write useful commit messages. Try following this template: ``` [#Issue] Summary Description <Macros> <Sign-Off> ``` ```shell $ git commit -am '[#123] Add some feature' ``` ### Push to the branch Push your locally committed changes to the remote origin (your fork): ```shell $ git push origin feature/123-something_awesome ``` ### Create a Pull Request Pull requests can be created via Git. Refer to [this document](https://docs.codeberg.org/collaborating/pull-requests-and-git-flow/) for detailed steps on how to create a pull request. After a Pull Request gets peer reviewed and approved, it will be merged. ## Code Style The names of Python variables, functions and classes must comply with [PEP8](https://peps.python.org/pep-0008) rules, in particular: * Name of a variable/function must be in snake_case (lowercase, with words separated by underscores as necessary to improve readability). * Name of a global variable must be in UPPER_SNAKE_CASE, the underscore (`_`) symbol must be used as a separator between words. * Name of a class must be in PascalCase (the first letter of each compound word in a variable name is capitalized). * Names of other variables should not be ended with the underscore symbol. Line length limit is set as 100 characters. Imports should be ordered in accordance with [isort default rules](https://pycqa.github.io/isort/). We use `black` and `isort` for code formatting. Please, refer to [Black code style](https://black.readthedocs.io/en/stable/the_black_code_style/current_style.html) for details. Type hints are mandatory for library's code: - class attributes; - function or method's parameters; - function or method's return type. The only exception is return type of test functions or methods - there's no much use in specifying `None` as return type for each test function. Do not use relative imports. Even if the module is in the same package, use the full package name. To format docstrings, please, use [Google Style Docstrings](https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html). Type annotations should be specified in the code and not in docstrings (please, refer to [this sample](https://sphinxcontrib-napoleon.readthedocs.io/en/latest/index.html#type-annotations)). ## DCO Sign off All authors to the project retain copyright to their work. However, to ensure that they are only submitting work that they have rights to, we are requiring everyone to acknowledge this by signing their work. Any copyright notices in this repository should specify the authors as "the contributors". To sign your work, just add a line like this at the end of your commit message: ``` Signed-off-by: Samii Sakisaka <samii@nspcc.ru> ``` This can easily be done with the `--signoff` option to `git commit`.
