gsutil utilizes as many cores as possible, and will create many threads too. In combination with gclient doing the same thing (utilize as many cores as possible), this results in creating way too many processes and some builders are running out of resources (e.g. can't create threads). This limits number of gsutil cp commands in git_cache to two.

depot_tools
Tools for working with Chromium development. It requires python 2.7 or 3.8 for python 3 support.
Tools
The most important tools are:
fetch: Agclientwrapper to checkout a project. Usefetch --helpfor 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. Usegclient helpfor more details and README.gclient.md.git cl: A code review tool to interact with Rietveld or Gerrit. Usegit cl helpfor 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.
Updating
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.

cpplint.py
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.
