Reland "Check whether goma is running when it is enabled" This reverts commit 428143ee24c5f084c8dfb38cd17f07b4f7ba9bf7. Reason for revert: Fixing the issues revealed by the original change by avoiding python3 and by checking for the existence of gomacc[.exe] before running it. This also relands 2241db8a1f6c05325c8a0c9eb5426d96cd6fa984 - "Avoid capture_output to support Python 3.6", to simplify relanding and any possible reverts.

This can > > lead to ~1,000 failed compile steps, which is messy. > > > > This change teaches autoninja.py to check whether goma is running. If > > not then it tells autoninja to just print a warning message. The > > check costs roughly 30 ms which seems reasonable. > > > > In fact, because this change also switches away from vpython (necessary > > to use python3 to use subprocess.run) it actually runs about 600 ms > > _faster_ than before this change. > > > > If build acceleration is requested through use_rbe then no checking for > > whether the service is running is done.

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
.
To contribute change for review:
git new-branch <somename> # Hack git add . git commit -a -m "Fixes goat teleporting" # find reviewers git cl owners git log -- <yourfiles> # Request a review. git cl upload -r reviewer1@chromium.org,reviewer2@chromium.org --send-mail # Edit change description if needed. git cl desc # If change is approved, flag it to be committed. git cl set-commit # If change needs more work. git rebase-update ... git cl upload -t "Fixes goat teleporter destination to be Australia"

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.
