Development Resources/Handling Git Contributions
Git makes it easy to pull contributions from other repositories and make them part of your own. It feels wrong to do the same thing we do with CVS: attach a patch that is later added to the repository by a committer. The natural thing to do in Git is to pull the contribution in question from the contributor's Git repository. Regardless of the mechanism used to actually get the code into an Eclipse project's Git repository, the Eclipse IP Policy and Due Diligence Process must be followed.
An individual has forked one of the eclipse.org projects and has issued a pull request for a commit record that they would like to contribute to the eclipse.org project.
- Eclipse project committer agrees the contribution is something they would like to include in their project.
- Contributor or project committer creates a bugzilla that includes a URL pointer to the commit record in the source repository.
- A copy of the code is attached (in patch format, see below) to the Bugzilla entry for archival purposes.
- The contributor provides a statement regarding the provenance, rights, and license of the code (see below)
- If required by the IP Due Diligence Process (e.g. if the contribution exceeds 250 lines), the committer creates a CQ and waits for "check in" permission
- Project committer merges the pull request back into the eclipse.org project git repository.
- Note that the committer does not need to take the code from bugzilla.
The Git show command can be used to generate a "patch format" suitable for attachment to the bug:
git show [commit] > patch.txt
Provenance, Rights, and License
We require that the contributor assert the following on each contribution before any code is introduced into an eclipse.org repository:
- I authored 100% of the contribution
- I have the rights to contribute the content to Eclipse
Gerrit provides facilities to capture all of the required information and can be used to do so. As of this writing, however, only the EGit and JGit projects have been authorized by the Eclipse Foundation to use Gerrit. Implementing Gerrit is a priority for the webmaster and we are hopeful that it will be addressed in the near future.
