Bug-Tracker

How to close Trac issues automatically via email

It searches commit messages for text in the form of:

• command #1
• command #1, #2
• command #1 & #2
• command #1 and #2
  

You can have more then one command in a message. The following commands are supported. There is more then one spelling for each command, to make this as user-friendly as possible.

• closes, fixes

  The specified issue numbers are closed with the contents of this
  commit message being added to it.

• references, refs, addresses, re

  The specified issue numbers are left in their current status, but
  the contents of this commit message are added to their notes.

A fairly complicated example of what you can do is with a commit message of:

   Changed blah and foo to do this or that. Fixes #10 and #12, and refs #12.

This will close #10 and #12, and add a note to #12.

License Issues

• Contributed code must be GPL'd (preferrably GPLv2 or any later version), or at least have a GPL-compatible license.

Sign-off Procedure

Verbatim copy from the Linux kernel (we might modify this a bit):

To improve tracking of who did what, especially with patches that can
percolate to their final resting place in the kernel through several
layers of maintainers, we've introduced a "sign-off" procedure on
patches that are being emailed around.

The sign-off is a simple line at the end of the explanation for the
patch, which certifies that you wrote it or otherwise have the right to
pass it on as a open-source patch.  The rules are pretty simple: if you
can certify the below:

       Developer's Certificate of Origin 1.1

       By making a contribution to this project, I certify that:

       (a) The contribution was created in whole or in part by me and I
           have the right to submit it under the open source license
           indicated in the file; or

       (b) The contribution is based upon previous work that, to the best
           of my knowledge, is covered under an appropriate open source
           license and I have the right under that license to submit that
           work with modifications, whether created in whole or in part
           by me, under the same open source license (unless I am
           permitted to submit under a different license), as indicated
           in the file; or

       (c) The contribution was provided directly to me by some other
           person who certified (a), (b) or (c) and I have not modified
           it.

       (d) I understand and agree that this project and the contribution
           are public and that a record of the contribution (including all
           personal information I submit with it, including my sign-off) is
           maintained indefinitely and may be redistributed consistent with
           this project or the open source license(s) involved.

then you just add a line saying

       Signed-off-by: Random J Developer <random@developer.example.org>

Some people also put extra tags at the end.  They'll just be ignored for
now, but you can do this to mark internal company procedures or just
point out some special detail about the sign-off.
