Contributor License Agreement
|
|
=============================
|
|
|
|
In order for us to accept code submissions (merge git pull-requests), contributors
|
|
need to sign the Contributor License Agreement (CLA). There are two CLAs, one for
|
|
individuals and one for corporations. As for the end-user license, both are based
|
|
on Apache. They are found in the code repository (`individual form
|
|
<https://github.com/PixarAnimationStudios/OpenSubdiv/blob/master/OpenSubdivCLA_individual.pdf>`__,
|
|
`corporate form <https://github.com/PixarAnimationStudios/OpenSubdiv/blob/master/OpenSubdivCLA_corporate.pdf>`__).
|
|
Please email the signed CLA to opensubdiv-cla@pixar.com.

Understand Git
|
|
==============
|
|
|
|
First, you should familiarize yourself with the Git data model and commands.
|
|
|
|
For small changes you may not need to understand Git deeply, but for larger
|
|
changes or working with the codebase over a long period of time, it becomes
|
|
critical to understand more of what's going on under the hood.
|
|
|
|
There are many free resources on the internet, one which we've found useful is
|
|
the following e-book:
|
|
|
|

Recommended Git Workflow
|
|
========================
|
|
|
|
Once you have a local development tree cloned and working, you can start making
|
|
changes. You will need to integrate changes from the source tree as you work;
|
|
the following outlines the workflow used by core OpenSubdiv engineers at Pixar
|
|
and DreamWorks:
|
|
|
|
#. Fork the master repository into your own local copy. This can be done via the
|
|
GitHub website using the "fork" button.
|
|
|
|
#. Clone your fork locally:
|
|
|
|
| git clone <your_fork_url> OpenSubdiv.<your_name>
|
|
|
|
|
| e.g.:
|
|
| git clone https://github.com/jcowles/OpenSubdiv.git OpenSubdiv.jcowles
|
|
|
|
#. Setup two remotes, **origin** and **upstream**. Origin will be setup as a
|
|
result of cloning your remote repository, but upstream must be setup manually:
|
|
|
|
| git remote add **upstream** https://github.com/PixarAnimationStudios/OpenSubdiv.git
|
|
|
|
Verify your remotes are setup correctly:
|
|
|
|
| git remote -v
|
|
|
|
Which should look something like:
|
|
|
|
| origin https://github.com/jcowles/OpenSubdiv.git (fetch)
|
|
| origin https://github.com/jcowles/OpenSubdiv.git (push)
|
|
| upstream https://github.com/PixarAnimationStudios/OpenSubdiv.git (fetch)
|
|
| upstream https://github.com/PixarAnimationStudios/OpenSubdiv.git (push)
|
|
|
|
Finally, fetch the upstream content (this is required for the next step):
|
|
|
|
| git fetch upstream
|
|
|
|
#. Setup a new branch for each change. Working with branches in Git is its
|
|
greatest pleasure, we strongly suggest setting up a new branch for each
|
|
change which you plan to pull-request.
|
|
|
|
All work is done in the "dev" branch, so be sure to keep your change in sync
|
|
with this upstream branch. To begin, start your new branch from the dev
|
|
branch:
|
|
|
|
| git checkout -b dev-feature upstream/dev
|
|
|
|
#. As you are working on your feature, new changes will be merged into the
|
|
upstream repository, to sync these changes down and preserve your local
|
|
edits, you can continually rebase your local work:
|
|
|
|
| git pull --rebase upstream dev
|
|
|
|
Notice the "--rebase" option here. It updates the current branch to the
|
|
upstream/dev branch and rebases all edits so they are at the head of your
|
|
local feature branch.
|
|
|
|
Alternatively, you can rebase all your work at once when your feature is
|
|
complete.
|
|
|
|
Sending a Pull Request
|
|
======================
|
|
|
|
First, rebase and squash your changes appropriately to produce a clean set of
|
|
changes at the head of your tree. We require changes to be grouped locally to
|
|
ensure that rolling back changes can be done easily.
|
|
|
|
If you've followed the steps above, your pending change should already be queued
|
|
up as required. If you have not, you may need to rebase and squash changes at
|
|
this point.
|
|
|
|
Once the change is clean, push your changes to "origin" and go to the GitHub
|
|
website to submit your pull request.
|
|
|
|
Be sure to submit your request against the "dev" branch.
