Pass large -j value to ninja when use_rbe = true The goma-on-borg backend is turning down. While chromium can continue using the goma client for build acceleration, the backend is swapped out to instead use Remote Build Execution, a gcloud service. Other downstream projects (e.g. Nest) switched out the goma frontend as well as the backend to RBE. These projects use a |use_rbe| gn flag to enable build acceleration through RBE. This change allows autoninja to recognize this flag and treat it as if it was using goma for the purposes of passing an appropriate -j flag. Bug: None Test: run on an out/ directory with use_rbe enabled Change-Id: I52d5771e92e9163234811b154fd36816639bf1b8 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/tools/depot_tools/+/2391009 Reviewed-by: Bruce Dawson <brucedawson@chromium.org> Commit-Queue: Simeon Anfinrud <sanfin@chromium.org>
Tools for working with Chromium development. It requires python 2.7 or 3.8 for python 3 support.
The most important tools are:
fetch
: A gclient
wrapper to checkout a project. Use fetch --help
for more details.gclient
: A meta-checkout tool. Think repo or git submodules, except that it support OS-specific rules, e.g. do not checkout Windows only dependencies when checking out for Android. Use gclient help
for more details and README.gclient.md.git cl
: A code review tool to interact with Rietveld or Gerrit. Use git cl help
for more details and README.git-cl.md.roll-dep
: A gclient dependency management tool to submit a dep roll, updating a dependency to a newer revision.There are a lot of git utilities included.
depot_tools
updates itself automatically when running gclient
tool. To disable auto update, set the environment variable DEPOT_TOOLS_UPDATE=0
.
To update package manually, run update_depot_tools.bat
on Windows, or ./update_depot_tools
on Linux or Mac.
On Windows only, running gclient
will install git
and python
.

Until 2018, our cpplint.py
was a copy of the upstream version at https://github.com/google/styleguide/tree/gh-pages/cpplint. Unfortunately, that repository is not maintained any more. If you want to update cpplint.py
in depot_tools
, just upload a patch to do so. We will figure out a long-term strategy via issue https://crbug.com/916550.
Note that the cpplint.py
here is also used by the Tricium analyzer, so if the cpplint.py here changes, we should also update the copy used there.
