OE has quite many patches that are just too valuable to keep to ourselves. OE encourages the following soft policy for adding patches to the repository.

By the way, Debian, [Ubuntu], Gentoo as well as Fedora are of course always a great source for grabbing high-quality patches to include in OE.


1) first line in a patch starts with upstream: and goes on to list the
   URL where the bug has been reported upstream or "OE-only" if the patch 
   is just a hack or applicable only to OE.
2) further information can optionally be listed in the following fields.
   Adding them is strongly encouraged where appropriate.

   * status: pending, accepted in XXX, rejected (upstream)
   * origin: where the patch has been stolen  ;-) 
   * comment: any further detail such as description or reason for
              application of the patch

Take a look at an example


These are sprints in the spirit of our bug-squashing weekends when we try to push our patches to the upstream projects. The first such sprint was held on short notice from Friday, February 15th 2008 to Monday, the 18th. A few patches were already pushed upstream. Second sprint is scheduled for first weekend in August.

Pushing our bugs upstream is beneficial for us (easier maintainability) and them (we give back our work). The following two commands can give you a list of patches still in need of being documented in line with above policy.

find recipes/ \( -name '*.patch' -or -name '*.diff' \) -print0 | xargs -0 egrep -L \^upstream\:

You can push those patches upstream even if you are only a normal user of OE. Let us know via the bug tracker if you have reported one of our patches upstream. Please be sure to test if the patch is still being applied to the most recent version of the package in OE.
