update-v8

CLI to simplify updates of V8 in the Node.js project

Installation

$ npm install -g update-v8

Please note that this tool uses async/await syntax and therefore requires Node.js 7.6.0 or higher.

Usage

This tool will maintain a clone of the V8 repository in ~/.update-v8/v8

update-v8 minor

Compare current V8 version with latest upstream of the same major. Applies a patch if necessary.
If the git apply command fails, a patch file will be written in the current directory.

update-v8 major --branch=branchName

Replaces deps/v8 with the lkgr branch or with branchName if it is specified. Resets the embedder version number to 0.

update-v8 backport --sha=SHA

Fetches and applies the patch corresponding to SHA. Increments the V8 patch version or embedder version number and commits the changes.
If the git apply command fails, a patch file will be written in the current directory.

Options

--no-bump

In case of backports, do not bump the V8 patch number or embedder string.

--node-dir=/path/to/node

Specify path to the Node.js git repository. Defaults to current working directory.
