We follow the Chromium code of conduct in our our repos and organizations, mailing lists, and other communications.
Please use crbug.com issue tracker. Relevant components to file bugs to include "Speed", "Test>Telemetry", "Speed>Dashboard", "Speed>Tracing", and "Speed>Bisection".
Do not use the github issue tracker.
Note: If you are a chromium project contributor and already have a chromium/src checkout,
you probably want to use the clone of this repo under that checkout's third_party
directory instead of cloning and editing this repo directly.
See Contributing from a Chromium checkout
for details.
Install depot_tools.
Then checkout the catapult repo.
git clone https://chromium.googlesource.com/catapult
You can then create a local branch, make and commit your change.
cd catapult
git checkout -t -b foo origin/master
... edit files ...
git commit -a -m "New files"
Once you're ready for a review do:
git cl upload
Once uploaded you can view the CL in Gerrit and request a review by clicking the "Start Review" button, and adding a reviewer from the OWNERS file. You can also click the "CQ Dry Run" button to run all the tests on your change.
If you get review feedback, edit and commit locally and then do another upload with the new files. Before you commit you'll want to sync to the tip-of-tree. You can either merge or rebase, it's up to you.
Then, submit your changes through the commit queue by checking the "Commit" box.
Once everything is landed, you can cleanup your branch.
git checkout master
git branch -D foo
If you get errors running git cl:
Credentials for the following hosts are required:
github-review.com
github.com
Then you cloned the github url of this repository. That confuses git cl /o.
To make things work, you'll need to re-clone from
https://chromium.googlesource.com/catapult for things to work.
If you're new to the chromium-family of projects, you will also need to sign the chrome contributors license agreement. You can sign the Contributor License Agreement, which you can do online. It only takes a minute. If you are contributing on behalf of a corporation, you must fill out the Corporate Contributor License Agreement and send it to us as described on that page.
If you've never submitted code before, you must add your (or your organization's) name and contact info to the Chromium AUTHORS file.
Next, ask an admin to add you (see adding committers)
If you already have catapult checked out as part of a Chromium checkout and want to edit it in place (instead of having a separate clone of the repository), you will probably want to disconnect it from gclient at this point so that it doesn't do strange things on updating. This is done by editing the .gclient file for your Chromium checkout and adding the following lines:
'custom_deps': {
'src/third_party/catapult': None,
},
In order to be able to land patches, you will most likely need to update the
origin remote in your catapult checkout to point directly to this GitHub
repository. You can do this by executing the following command inside the
catapult folder (third_party/catapult):
git remote set-url origin https://chromium.googlesource.com/catapult
See the style guide.
Look to individual project documentation for more info on getting started:
Check individual project documentation for instructions on how to run tests. You can also check the current status of our tests on the waterfall. Use the "Submit to CQ" button in Gerrit to commit through the commit queue, which automatically runs all tests. Run the tests before committing with the "CQ dry run" button.
Chromium's DEPS file needs to be rolled to the catapult revision containing your change in order for it to appear in Chrome's about:tracing or other third_party/catapult files. Follow the directions for rolling DEPS to do this.
Please read the directory structure guide to learn the conventions for new directories.
