A Major Overhaul of Eclipse’s IP Process: CLAs, signed-off-by and more

Thursday, February 21, 2013 - 08:00 by Mike Milinkovich

I’m very happy to announce that we are going to be making some fairly significant changes to the workflows and processes around how contributions flow into Eclipse projects, and how Eclipse committers will process them. The good news is that we think that the new approaches are going to make things a lot easier for everyone. For more details, you can take a look at the presentation I did at a recent Architecture Council meeting.

First, a quick summary of how contributions come into Eclipse today.

  • A contributor makes some changes to an Eclipse project and sends them to Eclipse for review and acceptance by an Eclipse committer. The first complication is that there are several different ways that can happen: contributions can come as push to Gerrit, or a patch in Bugzilla. Which means that the conversations about contributions can occur in multiple places.
  • Assuming the committer likes the contribution and wants to take it, they are then required to ask the contributor “The Three Questions” on either Gerrit or Bugzilla. The Three Questions are:
    1. Did you author 100% of the content you’re contributing?
    2. Do you have the rights to contribute this content to Eclipse?
    3. Are you willing to contribute the content under the project’s license(s) (e.g. EPL)

The problem with this approach is that it’s very manual, error prone, and annoying. In particular, asking a prolific contributor the same three questions each and every time they try to help you out is just not helpful. It is particularly annoying in the context of the normal git workflows, where there there are numerous conventions for dealing with contributions.

So here’s how we are going to make it better:

  • First, we are going to implement Contributor License Agreements (CLAs) for all contributors at Eclipse. The CLA will be a short document that essentially asks The Three Questions once. We will collect some information about the contributor so that we have a record on file of who is giving us code or documentation. Note that the Eclipse Foundation CLA will be quite different from those in use at other organizations. For example, Apache’s CLAs basically give the ASF a license equivalent to ownership for contributions. The Oracle Contributor Agreement (OCA) used by OpenJDK community gives Oracle joint ownership of contributions. The Eclipse CLA is much more modest. In terms of licenses, all it says is that the contributor agrees that their contributions will be provided under the license(s) for the project they’re contributing to. You can review and discuss the draft CLA on bug 401349.
  • Second, we are going to support signed-off-by for contributions which flow to Eclipse project via git and Gerrit. The goal here is to make it as simple as possible for Eclipse projects to accept contributions via the community best practices which have grown up around git. As part of this, we will be developing a contributor certificate of originality, inspired by the one used by the Linux community.
  • And finally, we are going to automate as much of this workflow as possible. Our CLAs will be presented and completed on-line. There will be Gerrit support so committers get an immediate indication as to whether a contributor has a CLA on file. There will be git triggers which will reject a commit where there is no CLA on file for the author of the code commit.

There are a ton of details to be worked out, not least of which is the timetable to roll all of this out. Stay tuned for that. If you want to get involved in the conversation, please join in on bug 401236.

Update: fixed typo “we think we think” in the first paragraph.
