All Pull Requests should be based off of and opened against the `master` branch. + + +2. Search [Existing PRs](https://github.com/fetchai/fetchd/pulls) for an open or closed PR that relates to your submission. + You don't want to duplicate existing efforts. + + +3. Be sure that an issue exists describing the problem you're fixing, or the design for the feature you'd like to add. + + +4. [Fork](https://docs.github.com/en/github/getting-started-with-github/fork-a-repo) the [repository](https://github.com/fetchai/fetchd). + + +5. In your forked repository, make your changes in a new git branch created off of the `master` branch. + +6. Make your changes, **including test cases and documentation updates where appropriate**. + +7. Follow our [coding rules](#rules). + + +8. Run all tests and checks locally, as described in the [development guide](DEVELOPING.md), and ensure they pass. This saves CI hours and ensures you only commit clean code. + + +9. Commit your changes using a descriptive commit message that follows our [commit message conventions](#commit). + +10. Push your branch to GitHub. + +11. In GitHub, send a pull request to `fetchai:master`. + +#### Reviewing a Pull Request + + +The repository maintainers reserve the right not to accept pull requests from community members who haven't been good citizens of the community. Such behavior includes not following our [code of conduct](CODE_OF_CONDUCT.md) and applies within or outside the managed channels. + + +When you contribute a new feature, the maintenance burden is transferred to the core team. This means that the benefit of the contribution must be compared against the cost of maintaining the feature. + +#### Addressing review feedback + +If we ask for changes via code reviews then: + +1. Make the required updates to the code. + +2. Re-run the tests and checks to ensure they are still passing. + +3. Create a new commit and push to your GitHub repository (this will update your Pull Request). + +#### After your pull request is merged + +After your pull request is merged, you can safely delete your branch and pull the changes from the (upstream) repository. + +## Coding Rules + +To ensure consistency throughout the source code, keep these rules in mind as you are working: + + +- All code must pass our code quality checks (linters, formatters, etc). See the [development guide](DEVELOPING.md) section for more detail. + + +- All features **must be tested** via unit-tests and if applicable integration-tests. Bug fixes also require tests, because the presence of bugs usually indicates insufficient test coverage. Tests help to: + + 1. Prove that your code works correctly, and + 2. Guard against future breaking changes and lower the maintenance cost. + +- All public features **must be documented**. +- Keep API compatibility in mind when you change any code. Above version `1.0.0`, breaking changes can happen across versions with different left digit. Below version `1.0.0`, they can happen across versions with different middle digit. Reviewers of your pull request will comment on any API compatibility issues. + +## Commit Message Convention + +This project uses Conventional Commits to generate release notes and to determine versioning. Please follow the [Conventional Commits v1.0.0](https://www.conventionalcommits.org/en/v1.0.0/). The commit types must be one of the following: + +- **chore**: Commits that don't directly add features, fix bugs, or refactor code, but rather maintain the project or its surrounding processes. +- **ci**: Changes to our CI configuration files and scripts +- **docs**: Changes to the documentation +- **feat**: A new feature +- **fix**: A bug fix +- **refactor**: A code change that neither fixes a bug nor adds a feature +- **test**: Adding missing tests or correcting existing tests +- **revert**: Reverts a previous commit that introduced an issue or unintended change. This essentially undoes a previous commit. +- **style**: Changes that only affect code formatting or style, without affecting functionality. This ensures consistency and readability of the codebase. +- **perf**: Changes that improve the performance of the project. + +Commit messages should adhere to this standard and be of the form: + + ```bash + git commit -m "feat: add new feature x" + git commit -m "fix: fix bug in feature x" + git commit -m "docs: add documentation for feature x" + git commit -m "test: add test suite for feature x" + ``` + +Further details on `conventional commits` can be found [here](https://www.conventionalcommits.org/en/v1.0.0/). + +## Merging Pull Requests + +When merging a branch, PRs should be squashed into one conventional commit by selecting the `Squash and merge` option. This ensures Release notes are useful and readable when releases are created. + +See [Merge strategies](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/incorporating-changes-from-a-pull-request/about-pull-request-merges#squash-and-merge-your-commits) from the official GitHub documentation. diff --git a/SECURITY.md b/SECURITY.md index 205758488..4c272026a 100644 --- a/SECURITY.md +++ b/SECURITY.md @@ -1,16 +1,22 @@ # Security Policy -Security is very important for Fetch.ai and its community.
