What to do if your CL broke the Node.js integration build
Node.js master uses V8 stable or beta. For additional integration, the V8 team builds Node with V8 master, i.e., with a V8 version from today. We provide integration bots for Linux, Windows, and Mac.
node_ci_linux64_rel bot fails on the V8 Commit Queue, there is either a legitimate problem with your CL (fix it) or Node must be modified. If the Node tests failed, search for “Not OK” in the log files. This document describes how to reproduce the problem locally and how to make changes to V8’s Node fork if your V8 CL causes the build to fail.
Follow the instructions at the node-ci repository to check out source.
Test changes to V8 #
V8 is set up as a DEPS dependency of node-ci. You may want to apply changes to V8 for testing or to reproduce failures. To do so, add your main V8 checkout as remote:
git remote add v8 <your-v8-dir>/.git
git fetch v8
git checkout v8/<your-branch>
Remember to run gclient hooks before compiling.
JOBS=4 make test
Make changes to Node.js #
Node.js is also set up as a
DEPS dependency of node-ci. You may want to apply changes to Node.js to fix breakages that V8 changes may cause. V8 tests against a fork of Node.js. You need a GitHub account to make changes to that fork.
Get the Node sources #
Fork V8’s Node.js repository on GitHub (click the fork button) unless you already did previously.
Add your both your fork and V8’s fork as remotes to the existing checkout:
git remote add v8 http://github.com/v8/node
git remote add <your-user-name> http://github.com//<your-user-name>/node
git checkout node-ci-<sync-date>
git checkout -b make-changes
Make your changes to the Node.js checkout, and commit them. Then push the changes to GitHub and create a pull request against the branch
<sync-date> is the date we sync’ed with upstream Node.js. Choose the latest date.
git push <your-user-name> make-changes
Once the pull request has been merged to V8’s fork of Node.js, you need to update node-ci’s
DEPS file, and create a CL.
git checkout -b update-deps
gclient setdep --var=node_revision=`(cd node && git rev-parse make-changes)`
git add DEPS
git commit -m 'Update Node'
git cl upload
