Before You Begin

To familiarize yourself with Solum, try it out using the information in our Getting Started Guide. When you are ready to start contributing, you will need to execute an OpenStack CLA. This is required before you can submit reviews to our Solum StackForge Repo. For information about how prepare for contribution, please consult the How To Contribute wiki page.

Learn About Gerrit

Be sure to read the Gerrit Workflow wiki page for information about how to submit your commit for review so it can be merged into the Solum code base.

Setting up your git review settings

 git config --global user.name "Firstname Lastname"
 git config --global user.email "your_email@youremail.com"
 git config --global gitreview.username "your_launchpad_username"

To check your git configuration:

 git config --list

Installing git-review

On Ubuntu, MacOSx, or most other Unix-like systems, it is as simple as:

 pip install git-review

There are other installation options detailed in the Installation Instructions. You can now check out the Solum code and begin working on it:

Your first commit

Set up your local branch

 git clone git://git.openstack.org/stackforge/solum
 cd solum
 git checkout -b [branch name]
 git review -s

Write some awesome code

At this point can write your code and push it to Gerrit for review.

 git add <list of files you added/changed>
 git commit -a
 git review -v --draft

Once you are happy with your code and want it to be reviewed you want to convert it from a Draft. "Sign In" at https://review.openstack.org/ and after verifying the review yourself hit the "Publish" button on the page.

If you know you are ready for others to review your code, you can skip the draft step and just do:

git review -v

If you want to revise your patchset in the review system in response to feedback, make your changes, then use:

git commit -a --amend
git review -v

Upon approval of the review your code will be automatically merged.

Reviews

The OpenStack CI system uses the concept of core reviewers. These are individuals who have consistently reviewed code for the project, and helped over a considerable period of time to improve the quality and consistency of what we merge into the code base. Project contributors will feel that this reviewer is a positive influence on the team and that they maintain the values and traditions of the OpenStack development community.

Policies

Existing core reviewers may nominate new ones in an ML thread. Consent among the current reviewers shall result in the declaration of the new core reviewer by the PTL. Lack of unanimous consent shall be carefully considered, and a final decision informed by input from from active team members shall be made by the PTL. Core reviewers who are judged by their peers in the core review group to fall short of the expectations for contribution of a core reviewer may be nominated for return to regular reviewer status.

The current Gerrit policy is:

label-Code-Review = -2..+2 group solum-core
label-Approved = +0..+1 group solum-core

Patches require a core reviewer to mark a review as "Approved" before they are merged.

Review Guidelines

A -1 vote is an opportunity to make our code better before it is merged. Please do your best to make helpful, actionable -1 votes.

  • Avoid the temptation to blindly +1 code without reviewing it in sufficient detail to form an opinion.
  • For Approval, two core reviewers should supply a +2.
  • If a patch submitted by one contributor is picked up and completed by another contributor, special handling of the resolution should be used.
  • When voting -1 on a contribution, it means that you want the submitter to make a revision in accordance with your feedback before core reviewers should consider this code for merge.
  • If you ask a question, you should vote -0 unless you anticipate that the answer to that question is likely to cause you to vote against the submission without further revisions.
  • If you use a -1 vote for a question, and the contributor answers the question, please respond acknowledging the question. Either change your vote or follow up with additional rationale for why this should remain a -1 comment.
