First of all, thank you for wanting to contribute to Bau.MSBuild! We really appreciate all the awesome support we get from our community. We want to keep it as easy as possible to contribute changes that get things working in your environment. There are a few guidelines we need contributors to follow to keep the project flowing smoothly.
Before starting work on a functional change, i.e. a new feature, a change to an existing feature or a bug, please ensure an issue has been raised. If not, go ahead and raise one. Indicate your intention to work on the issue by writing a comment against it. This will prevent duplication of effort. If the change is non-trivial, it's usually best to propose a design in the issue comments.
It is not necessary to raise an issue for non-functional changes, e.g. refactoring, adding tests, reformatting code, documentation, updating packages, etc.
All new features must be covered by unit tests in the Bau.MSBuild.Test.Unit project. Unit tests should be structured as Arrange, Act and Assert steps, labelled with comments.
Pull requests containing tabs will not be accepted. Make sure you set your editor to replace tabs with spaces. Indents for all file types should be 4 characters wide.
The repository is configured to preserve line endings both on checkout and commit (the equivalent of autocrlf set to false). This means you are responsible for line endings. We recommend that you configure your diff viewer so that it does not ignore line endings. Any wall of pink pull requests will not be accepted.
Try to keep lines of code no longer than 120 characters wide. This isn't a strict rule. Occasionally a line of code can be more readable if allowed to spill over slightly. A good way to remember this rule is to use the 'Column Guides' feature of the Productivity Power Tools extension for Visual Studio.
Try to keep your coding style in line with the existing code. It might not exactly match your preferred style but it's better to keep things consistent. StyleCop compliance is enforced through analysis on each build and the treatment of warnings as errors for release builds. Any StyleCop settings changes or suppressions must be clearly justified.
Try and avoid introducing code analysis violations. The non-test projects have largely been kept free of code analysis violations and we would like to keep it that way. Any code analysis rule changes or suppressions must be clearly justified.
Please do not add Resharper suppressions to code using comments. You may tweak your local Resharper settings but do not commit these to the repo.
- Fork on GitHub
- Clone your fork locally
- Configure the upstream repo (
git remote add upstream git://github.com/bau-build/bau.git) - Checkout the master branch (
git checkout master) - Create a local branch (
git checkout -b my-branch). The branch name should be descriptive, or it can just be the GitHub issue number which the work relates to, e.g.123. - Work on your feature
- Rebase if required (see 'Handling Updates from Upstream' below)
- Test the build locally by running
bau.bat
(see 'How to build') - Push the branch up to GitHub (
git push origin my-branch) - Send a Pull Request on GitHub (see 'Sending a Pull Request' below)
You should never work on a clone of master, and you should never send a pull request from master - always from a branch. The reasons for this are detailed below.
While you're working away in your branch it's quite possible that your upstream master may be updated. If this happens you should:
- Stash any un-committed changes you need to
git checkout mastergit pull upstream mastergit checkout my-branchgit rebase master my-branchgit push origin master(optional) this keeps the master branch in your fork up to date
These steps ensure your history is "clean" i.e. you have one branch from master followed by your changes in a straight line. Failing to do this ends up with several "messy" merges in your history, which we don't want. This is the reason why you should always work in a branch and you should never be working in or sending pull requests from master.
If you're working on a long running feature you may want to do this quite often to reduce the risk of tricky merges later on.
While working on your feature you may well create several branches, which is fine, but before you send a pull request you should ensure that you have rebased back to a single "Feature branch" - we care about your commits, and we care about your feature branch; but we don't care about how many or which branches you created while you were working on it :-)
When you're ready to go you should confirm that you are up to date and rebased with upstream master (see "Handling Updates from Upstream" above) and then:
git push origin my-branch- Send a descriptive Pull Request on GitHub.
- Make sure the pull request is from the branch on your fork to the bau-build/bau master branch.
- If your changes relate to a GitHub issue, add the issue number to the pull request description in the format #123.
- If GitHub determines that the pull request can be merged automatically, a test build will commence approximately one minute after you raise the pull request. The build status will reported on the pull request.
- If the build fails there may be a problem with your changes which you will have to fix before the pull request can be accepted. Follow the link to the build server (you can either create an account or login as guest) and inspect the build logs to see what caused the failure.
- Occasionally, build failures may be due to problems on the build server rather than problems in your changes. If you determine this to be the case, please add a comment on the pull request and one of the coordinators will address the problem.
The coordinators will review your pull request and provide any feedback required. If your pull request is accepted, your changes will be included in the next release. Look out for your name in the release notes 🏆.
If you contributed a new feature or a change to an existing feature then we are always very grateful to receive updates to the documentation (after the release to prevent confusion).
