[PATCH] D128645: Update developer policy.

[Edd Barrett via Phabricator via cfe-commits]

vext01 added inline comments.


================
Comment at: llvm/docs/DeveloperPolicy.rst:87
 
-#. Patches should be made with ``git format-patch``, or similar (see special
-   commands for `Requesting Phabricator review via the web interface
-   <Phabricator.html#phabricator-request-review-web>`_ ). If you use a
-   different tool, make sure it uses the ``diff -u`` format and that it
-   doesn't contain clutter which makes it hard to read.
-
-Once your patch is ready, submit it by emailing it to the appropriate project's
-commit mailing list (or commit it directly if applicable). Alternatively, some
-patches get sent to the project's development list or component of the LLVM bug
-tracker, but the commit list is the primary place for reviews and should
-generally be preferred.
-
-When sending a patch to a mailing list, it is a good idea to send it as an
-*attachment* to the message, not embedded into the text of the message.  This
-ensures that your mailer will not mangle the patch when it sends it (e.g. by
-making whitespace changes or by wrapping lines).
-
-*For Thunderbird users:* Before submitting a patch, please open *Preferences >
-Advanced > General > Config Editor*, find the key
-``mail.content_disposition_type``, and set its value to ``1``. Without this
-setting, Thunderbird sends your attachment using ``Content-Disposition: inline``
-rather than ``Content-Disposition: attachment``. Apple Mail gamely displays such
-a file inline, making it difficult to work with for reviewers using that
-program.
-
-When submitting patches, please do not add confidentiality or non-disclosure
-notices to the patches themselves.  These notices conflict with the LLVM
-licensing terms and may result in your contribution being excluded.
+#. Patches should be unified diffs with "infinte context" (i.e. using something
+   like `git diff -U 999999 main`).

Woah! I just realized that `-U 999999` and `-U999999` are interpreted differently by `git`. We need the latter.
