Evolving ChakraCore on Node.js with rebases instead of merges

The Node.js master branch is constantly evolving. The chakracore-master branch is also evolving, both by fixing breaking changes from master and by landing new things, making it better. The goal of the chakracore-master branch is to produce a set of easy to review commits, that can be used to open a pull request against master.

For the master branch in a given moment (tagged master-DATE), we can create a chakracore-DATE branch that represents the state of ChakraCore on Node for that revision of master. When updating master, the dated chakracore branch should be rebased against the new dated master branch, creating a new dated chakracore branch using a pull request. Updates to ChakraCore and ChakraShim should either replace the commits of the original versions, or, if the update should be separated, have a different pull request. A chakracore-master branch can be created pointing to the most recent version of ChakraCo
