All RAP source code is hosted in Git repositories. We use GitHub to review changes by committers and contributors.

See for current information.

Common Repository Structure

We've agreed on a common structure for all our Git repositories:

all bundle projects
feature projects
projects for release engineering
unit test projects
for bundles containing exemplary applications and demo code

Git Practices


  • Make commits of logical units, do not mix different topics in a single commit.
  • When splitting up bigger tasks into logical units, every single commit should produce a consistent version, i.e. the test suite must pass after every commit.
  • Make sure your commit does not introduce any unnecessary whitespace.
  • Make sure your commit does not include any commented code, sysouts, etc.
  • Make sure that the tests are included together with the fix.

Commit messages

Commit messages should follow the recommended format described in this article:

Capitalized, short (50 chars or less) summary

More detailed explanatory text, if necessary.  Wrap it to about 72
characters or so.  In some contexts, the first line is treated as the
subject of an email and the rest of the text as the body.  The blank
line separating the summary from the body is critical (unless you omit
the body entirely); tools like rebase can get confused if you run the
two together.

Write your commit message in the present tense: "Fix bug" and not "Fixed
bug."  This convention matches up with commit messages generated by
commands like git merge and git revert.

Further paragraphs come after blank lines.

- Bullet points are okay, too

- Typically a hyphen or asterisk is used for the bullet, preceded by a
  single space, with blank lines in between, but conventions vary here

- Use a hanging indent

Some further advice can be found here.

  • The commit message should be understandable when reading through the commit log. That's why it should be simple and should make sense also without context.
  • The body should explain the problem and the solution. It should also point out why the solution has been chosen, and what other alternatives have been considered, but discarded.
  • The explanation should be understandable without external resources. It's good to provide the URL to a discussion or a bug, but the important points should also be summarized in the commit message.

Committing patches

  • Make use the Author field in the commit is set to the original author.
  • When committing a patch from someone else, add a "Signed-off-by: Committer Name <committer@email>" line to the commit message, to confirm that you agree with the patch and made sure the patch is IP clean.
