[Announcement] Gerrit is now open for business!

[Aaron Gable]

Hi Chromium and Blink devs,

tl;dr: Use gerrit in chromium/src with git cl upload --gerrit! File bugs here! Let us know what you think!

As we've announced before, Chromium is in the process of changing over from using Rietveld for code review to using Gerrit. As of today, Gerrit is ready for the full force of your usage and testing. We'd like to invite all Chromium contributors to dogfood Gerrit for your code reviews.

Here are some things we've improved thanks to early dogfood feedback:

• Re-authentication after credentials expire is now easy and nearly seamless

• We no longer send separate emails to each person on the CC line

• Image diffs are now just as fast as text diffs

We also have some exciting stuff coming up soon:

• Themes for different hosts (e.g. external and internal), so you can tell them apart at a glance

• A Work-In-Progress mode that won't send any emails until you Publish your CL

• An easy way to reland CLs which have been reverted

Whenever you're uploading a code review against chromium/src.git, please consider uploading the change to Gerrit instead of Rietveld.

To upload a change to Gerrit instead of Rietveld, just run

   git cl upload --gerrit

when uploading the change for the first time. Additional patchsets after the first will automatically upload to the same review. If you would like all of your Chromium reviews to go to Gerrit without having to pass the flag, simply run

   git config --local gerrit.host true

in your local repository checkout. If you have done the above and need a temporary escape hatch, you can upload with git cl upload --rietveld, and please file a bug or send feedback about why you needed to switch back.

When using Gerrit, you should get the new UI (PolyGerrit) by default. If you don't (because you have used Gerrit in the past and expressed a UI preference then), please click the "New UI" link in the footer or follow this link to use the new one instead.

This FAQ should hopefully address any questions you might have. The settings page also has a lot of things you can tweak if they aren't to your liking. If you run into any issues interacting with your CLs from the command line or landing them via the commit queue, please file a bug here. If you run into any issues using the PolyGerrit web application, please file a bug at here.

We really value your feedback on Gerrit and want to hear about your experience using it so that we can continue improving it and make this transition as smooth as possible. We look forward to hearing from you!

Thanks,

Aaron

P.S. Yes, this does mean that we'll be using both Gerrit and Rietveld side-by-side for the near future. The more helpful the feedback we receive is, the quicker we'll be able to switch away from Rietveld entirely.
