In DEPS, comment out the part that looks like this.
# "src/third_party/angle": # Var("chromium_git") + "/angle/angle.git@" + Var("angle_revision"),
Delete or rename third_party/angle.
(Optional) sync and make sure the third_party/angle directory doesn't come back. It shouldn’t because it is no longer referenced from DEPS.
gclient sync -r CURRENT_REVISION
Clone the ANGLE git repository.
> git clone https://chromium.googlesource.com/angle/angle third_party/angle > gclient runhooks
To check ANGLE builds (assumes you ran hooks with GYP_GENERATORS=ninja) without building all of Chromium.
ninja -C out\Release libEGL.dll
Change files then commit locally.
Upload to Gerrit for review. You will need to have installed the git hook as described in the “Getting started with Gerrit for ANGLE” section of the ContributingCode doc before committing them locally.
git cl upload
As with subversion and Rietveld: visit the upload link for the review site, check the diff and the commit message then add reviewer(s) and publish.
Land your changes to the upstream repository from the Gerrit web interface.
If there are upstream changes, you may need to rebase your patches and reupload them.
git pull git cl upload
To roll DEPS, make sure this is not commented out and update the hash associated with “angle_revision”. (Your hash will be different than the one below.)
Your changes should now be in third_party/angle.
