How to contribute to finschia-kt

First of all, thank you so much for taking your time to contribute! It will be amazing if you could help us by doing any of the following:

Contributor license agreement

When you are sending a pull request and it's a non-trivial change beyond fixing typos, please sign the ICLA (individual contributor license agreement). Please contact us if you need the CCLA (corporate contributor license agreement).

Code of conduct

We expect contributors to follow our code of conduct.

Commit message and Pull Request message

  • Follow Conventional Commit to release note automation.
  • Don't mention or link that can't accessible from public.
  • Use English only. Because this project will be published to the world-wide open-source world. But no worries. We are fully aware of that most of us are not the English-native.

Pull Requests

To accommodate review process we suggest that PRs are categorically broken up. Ideally each PR addresses only a single issue. Additionally, as much as possible code refactoring and cleanup should be submitted as a separate PRs from bugfixes/feature-additions.

Process for reviewing PRs

All PRs require two Reviews before merge (except docs changes, or variable name-changes which only require one). When reviewing PRs please use the following review explanations:

  • LGTM without an explicit approval means that the changes look good, but you haven't pulled down the code, run tests locally and thoroughly reviewed it.
  • Approval through the GH UI means that you understand the code, documentation/spec is updated in the right places, you have pulled down and tested the code locally. In addition:
    • You must also think through anything which ought to be included but is not
    • You must think through whether any added code could be partially combined (DRYed) with existing code
    • You must think through any potential security issues or incentive-compatibility flaws introduced by the changes
    • Naming must be consistent with conventions and the rest of the codebase
    • Code must live in a reasonable location, considering dependency structures (e.g. not importing testing modules in production code, or including example code modules in production code).
    • if you approve of the PR, you are responsible for fixing any of the issues mentioned here and more
  • If you sat down with the PR submitter and did a pairing review please note that in the Approval, or your PR comments.
  • If you are only making "surface level" reviews, submit any notes as Comments without adding a review.

Forking

For instance, to create a fork and work on a branch of it, I would:

  • Create the fork on github, using the fork button.
  • Go to the original repo checked out locally
  • git remote rename origin upstream
  • git remote add origin [email protected]:someone/finshia-kt.git

Now origin refers to my fork and upstream refers to the finshia-kt version. So I can git push -u origin main to update my fork, and make pull requests to finshia-kt from there. Of course, replace someone with your git handle.

To pull in updates from the origin repo, run

  • git fetch upstream
  • git rebase upstream/main (or whatever branch you want)

Please don't make Pull Requests from main.

Dependencies

We use gradle to manage dependency versions.

The main branch of every Finshia-kt repository should just build with ./gradlew build

Testing

Tests can be ran by running ./gradlew test at the top level of the finshia-kt repository.

We expect tests to use Junit5 and Mockito.

Branching Model and Release

User-facing repos should adhere to the trunk based development branching model: https://trunkbaseddevelopment.com/.

Libraries need not follow the model strictly, but would be wise to.

This repo utilizes semantic versioning.

PR Targeting

Ensure that you base and target your PR on the main branch.

All feature additions should be targeted against main. Bug fixes for an outstanding release candidate should be targeted against the release candidate branch.

Development Procedure

  • the latest state of development is on main
  • main must never fail ./gradlew build test
  • no --force onto main (except when reverting a broken commit, which should seldom happen)
  • create a development branch either on github.com/Finschia/finschia-kt, or your fork (using git remote add origin)
  • before submitting a pull request, begin git rebase on top of main

Pull Merge Procedure

  • ensure pull branch is rebased on main
  • run ./gradlew test to ensure that all tests pass
  • merge pull request (We are using squash and merge for small features)

Release Procedure

  • Start on main
  • Create the release candidate branch rc/v* (going forward known as RC) and ensure it's protected against pushing from anyone except the release manager/coordinator
    • no PRs targeting this branch should be merged unless exceptional circumstances arise
  • On the RC branch, prepare a new version section in the CHANGELOG.md
    • All links must be link-ified
    • Copy the entries into a RELEASE_CHANGELOG.md, this is needed so the bot knows which entries to add to the release page on github.
  • After all test has successfully completed, create the release branch (release/vX.XX.X) from the RC branch
  • Create a PR to main to incorporate the CHANGELOG.md updates
  • Tag the release (use git tag -a) and create a release in Github
  • Delete the RC branches
