Add an optional no-auto-gc flag for the git fetch. Bug: b/458222057 Recipe-Nontrivial-Roll: chromiumos Change-Id: If00eb0639871b060bc5efc507e79620382c0dfe5 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/tools/depot_tools/+/7153382 Reviewed-by: Gavin Mak <gavinmak@google.com> Commit-Queue: Marc Jin <jmarc@google.com>
Tools for Chromium development. Requires Python 3.8+.
gsutil: Python 3.9–3.13 required.
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.
Also, includes shell script/batch file for tools required to build chromium, e.g.
gn: a meta-build system that generates build files for Ninjaautoninja: a wrapper for siso and ninja.siso: a build tool that aims to significantly speed up Chromium's build.ninja: a small build system with a focus on speed. deprecated by Siso.These shell script/batch file runs python script with python-bin/python3 that find binaries in chromium checkout, and run with proper setup/check. To use these wrappers, you need to initialize/bootstrap depot_tools (using gclient, update_depot_tools or ensure_bootstrap).
See set-up documentation.
depot_tools is also available in
chromium's third_party/depot_tools: propagated by autoroller.
on builder: infra_internal/recipe_bundles/chrome-internal.googlesource.com/chrome/tools/build bundles depot_tools. propagated by build_internal recipe roller
These depot_tools would not be initialized/bootstrapped (i.e. no python-bin/python3 binary available), so the build tool wrapper won't work, unless it is explicitly initialized by ensure_bootstrap. Or, directly call the python script instead of using the shell script/batch file.
depot_tools updates itself automatically when running gclient tool. To disable auto update, set the environment variable DEPOT_TOOLS_UPDATE=0 or run ./update_depot_tools_toggle.py --disable.
To update package manually, run update_depot_tools.bat on Windows, or ./update_depot_tools on Linux or Mac.
Running gclient will install python3 binary.

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.
