metadata: use os.walk to speedup metadata file discovery os.walk is more efficient than the current handwritten traversal. Measured the time to scan reduced from 30s+ to 8s on p920 on chromium/src. `followlinks=True` is set to preserve behavior that os.path.isdir returns True for symlink to directories, and the current traversal code will descend into those.

Tools for working with Chromium development. It requires python 3.8.
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
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.
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.
