Introduction

You are here to help BitShares and the python-bitshares library? Awesome, feel welcome and read the following sections in order to know how to ask questions and how to work on something.

Code of Conduct

All members of our community are expected to follow our Code of Conduct. Please make sure you are welcoming and friendly in all of our spaces.

Get in touch

Feel free to get in contact with the developer community on Telegram.

Contributing to development

When contributing to this repository, please first discuss the change you wish to make via issue, email, or any other method with the owners of this repository before making a change.

Please note we have a code of conduct, please follow it in all your interactions with the project.

Your First Contribution

To familiarize yourself with the code and procedures, we recommend to get started with:

  • review a Pull Request
  • fix an Issue
  • update the documentation
  • make a website
  • write a tutorial

Git Flow

This project makes heavy use of git flow. If you are not familiar with it, then the most important thing for you to understand is that:

pull requests need to be made against the develop branch!

Contributor License Agreement

Upon submission of a pull request, you will be asked to sign the Contributor License Agreement digitally through a github-connected service.

1. Where do I go from here?

If you've noticed a bug or have a question, [search the issue tracker][https://github.com/bitshares/python-bitshares/issues] to see if someone else in the community has already created a ticket. If not, go ahead and [make one][https://github.com/bitshares/python-bitshares/issues/new]!

2. Fork & create a branch

If this is something you think you can fix, then fork the repository and create a branch with a descriptive name.

A good branch name would be (where issue #325 is the ticket you're working on):

git checkout -b 325-new-fancy-feature

3. Get the test suite running

Make sure to add a unit tests for your your code contribution in tests/. You may use other unit tests as template for your own tests.

Individual unit tests can be run by:

python3 -m unittests tests/test_NEWFEATURE.py

The entire test suite can be run in a sandbox through

tox

4. Did you find a bug?

  • Ensure the bug was not already reported by [searching all issues][https://github.com/bitshares/python-bitshares/issues].

  • If you're unable to find an open issue addressing the problem, [open a new one][https://github.com/bitshares/python-bitshares/issues/new]. Be sure to include a title and clear description, as much relevant information as possible, and a code sample or an executable test case demonstrating the expected behavior that is not occurring.

  • If possible, use the relevant bug report templates to create the issue. Simply copy the content of the appropriate template into a .py file, make the necessary changes to demonstrate the issue, and paste the content into the issue description.

5. Implement your fix or feature

At this point, you're ready to make your changes! Feel free to ask for help; everyone is a beginner at first

6. Get the style right

Your patch should follow the same conventions & pass the same code quality checks as the rest of the project. Codeclimate will give you feedback in this regard. You can check & fix codeclimate's feedback by running it locally using Codeclimate's CLI, via codeclimate analyze.

7. Make a Pull Request

Pull requests are supposed to go against the develop branch, only!

At this point, you should switch back to your develop branch and make sure it's up to date with python-bitshares's develop branch:

git remote add upstream git@github.com:bitshares/python-bitshares.git
git checkout develop
git pull upstream develop

Then update your feature branch from your local copy of develop, and push it!

git checkout 325-new-fancy-feature
git rebase develop
git push --set-upstream origin 325-new-fancy-feature

Finally, go to GitHub and make a Pull Request :D

Travis CI will run our test suite against all supported Rails versions. We care about quality, so your PR won't be merged until all tests pass. It's unlikely, but it's possible that your changes pass tests in one Rails version but fail in another. In that case, you'll have to setup your development environment (as explained in step 3) to use the problematic Rails version, and investigate what's going on!

7. Keeping your Pull Request updated

If a maintainer asks you to "rebase" your PR, they're saying that a lot of code has changed, and that you need to update your branch so it's easier to merge.

To learn more about rebasing in Git, there are a lot of good git rebasing resources but here's the suggested workflow:

git checkout 325-new-fancy-feature
git pull --rebase upstream develop
git push --force-with-lease 325-new-fancy-feature

8. Merging a PR (maintainers only)

A PR can only be merged into develop by a maintainer if:

  • Pull request goes against develop branch.
  • It is passing CI.
  • It has been approved by at least two maintainers. If it was a maintainer who opened the PR, only one extra approval is needed.
  • It has no requested changes.
  • It is up to date with current develop.
  • Did the contributor sign the CLA

Any maintainer is allowed to merge a PR if all of these conditions are met.

9. Shipping a release (maintainers only)

Maintainers need to do the following to push out a release:

git checkout develop
git fetch origin
git rebase origin/develop
# get latest tag
git tag -l
# git flow
git flow release start x.y.z
# bump version in setup.py
git add setup.py; git commit -m "version bump"
git flow release finish

Bundling and pushing the release:

make release
