If you prefer to use a web user interface for code reviews, you can now submit your patches for Clang and LLVM at LLVM’s Phabricator.
There are two options to get an account on Phabricator. You can sign up immediately with one of the supported OAuth account types if you’re comfortable with OAuth, but you can also email firstname.lastname@example.org to request an account to be created manually without using OAuth. We’re working to get support in Phabricator to directly create new accounts, but currently this is a manual process.
Note that if you use your Subversion user name as Phabricator user name, Phabricator will automatically connect your submits to your Phabricator user in the Code Repository Browser.
Phabricator has a tool called Arcanist to upload patches from the command line. To get you set up, follow the Arcanist Quick Start instructions.
You can learn more about how to use arc to interact with Phabricator in the Arcanist User Guide.
The tool to create and review patches in Phabricator is called Differential.
Note that you can upload patches created through various diff tools, including git and svn. To make reviews easier, please always include as much context as possible with your diff! Don’t worry, Phabricator will automatically send a diff with a smaller context in the review email, but having the full file in the web interface will help the reviewer understand your code.
To get a full diff, use one of the following commands (or just use Arcanist to upload your patch):
To upload a new patch:
To submit an updated patch:
Phabricator allows you to add inline comments as well as overall comments to a revision. To add an inline comment, select the lines of code you want to comment on by clicking and dragging the line numbers in the diff pane.
You can add overall comments or submit your comments at the bottom of the page.
Phabricator has many useful features, for example allowing you to select diffs between different versions of the patch as it was reviewed in the Revision Update History. Most features are self descriptive - explore, and if you have a question, drop by on #llvm in IRC to get help.
