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`_.
|
|
|
|
Sign up
|
|
-------
|
|
|
|
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`_.
|
|
|
|
|
|
Requesting a review via the command line
|
|
----------------------------------------
|
|
|
|
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`_.
|
|
|
|
Requesting a review via the web interface
|
|
-----------------------------------------
|
|
|
|
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):
|
|
|
|
* ``git diff -U999999 other-branch``
|
|
* ``svn diff --diff-cmd=diff -x -U999999``
|
|
|
|
To upload a new patch:
|
|
|
|
* Click *Differential*.
|
|
* Click *Create Diff*.
|
|
* Paste the text diff or upload the patch file.
|
|
Note that TODO
|
|
* Leave the drop down on *Create a new Revision...* and click *Continue*.
|
|
* Enter a descriptive title and summary; add reviewers and mailing
|
|
lists that you want to be included in the review. If your patch is
|
|
for LLVM, cc llvm-commits; if your patch is for Clang, cc cfe-commits.
|
|
* Click *Save*.
|
|
|
|
To submit an updated patch:
|
|
|
|
* Click *Differential*.
|
|
* Click *Create Diff*.
|
|
* Paste the updated diff.
|
|
* Select the review you want to from the *Attach To* dropdown and click
|
|
*Continue*.
|
|
* Click *Save*.

Reviewing code with Phabricator
|
|
-------------------------------
|
|
|
|
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.
|
|
|
|
Note that as e-mail is the system of reference for code reviews, and some
|
|
people prefer it over a web interface, we do not generate automated mail
|
|
when a review changes state, for example by clicking "Accept Revision" in
|
|
the web interface. Thus, please type LGTM into the comment box to accept
|
|
a change from Phabricator.
|
|
|
|
Committing a change
|
|
-------------------
|
|
|
|
When committing an LLVM change that has been reviewed using
|
|
Phabricator, the convention is for the commit message to end with the
|
|
line:
|
|
|
|
::
|
|
|
|
Differential Revision: <URL>
|
|
|
|
where ``<URL>`` is the URL for the code review, starting with
|
|
``http://reviews.llvm.org/``.
|
|
|
|
Note that Arcanist will add this automatically.
|
|
|
|
This allows people reading the version history to see the review for
|
|
context. This also allows Phabricator to detect the commit, close the
|
|
review, and add a link from the review to the commit.
|
|
|
