Contribution guide

First, thank you for contributing! We love and encourage pull requests from everyone. Please follow the guidelines:

• Check the open issues and pull requests for existing discussions.

• Open an issue first, to discuss a new feature or enhancement.

• Write tests, and make sure the test suite passes locally and on CI.

• 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 tzhash 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 repository

Fork TZHash upstream source repository to your own personal repository. Copy the URL of your fork (you will need it for the git clone command below).

$ git clone https://git.frostfs.info/TrueCloudLab/tzhash

Set up git remote as upstream

$ cd tzhash
$ git remote add upstream https://git.frostfs.info/TrueCloudLab/tzhash
$ git fetch upstream
$ git merge upstream/master
...

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.

$ git checkout -b feature/123-something_awesome

Test your changes

After your code changes, make sure

• To add test cases for the new code.
• To squash your commits into a single commit or a series of logically separated commits run git rebase -i. It's okay to force update your pull request.
• To run make test and make all completes.

Commit changes

After verification, commit your changes. This is a great post on how to write useful commit messages. Try following this template:

[#Issue] <component> Summary

Description

<Macros>

<Sign-Off>

$ git commit -sam '[#123] Add some feature'

Push to the branch

Push your locally committed changes to the remote origin (your fork)

$ git push origin feature/123-something_awesome

Create a Pull Request

Pull requests can be created via git.frostfs.info. Refer to this document for detailed steps on how to create a pull request. After a Pull Request gets peer reviewed and approved, it will be merged.
