AffectedFiles carefully added a slash to dir_with_slash, but then called
normpath - which trims trailing path separators. This meant that
ui/views/PRESUBMIT.py would analyze files in ui\views_content_client,
leading to spooky action at a distance. This was noticed when this
command triggered a presubmit error:
git cl presubmit "--files=ui/views_content_client/*.cc;ui/views/readme.md"
when running presubmit on either file individually found nothing.
This change was tested by getting CheckChangeLintsClean to print the
files that it was asked to analyze, making the behavior quite obvious.
This bug appears to have existed for about thirteen years, but only
triggers in rare cases, and even then the incorrect behavior was almost
impossible to notice.
One of the tests was inadvertently testing the broken AffectedFiles
behavior and another seemed to be requiring it to handle '.'
correctly which I'm not sure we want to support.

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 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.

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.
