  15 See the manual for useful hacking informations, either by running

  19 or by checking the [[http://www.gnu.org/software/guix/manual/guix.html#Contributing][web copy of the manual]].

  21 * Commit Access
  22
  23 For frequent contributors, having write access to the repository is
  24 convenient.  When you deem it necessary, feel free to ask for it on the
  25 mailing list.  When you get commit access, please make sure to follow the
  26 policy below (discussions of the policy can take place on guix-devel@gnu.org.)
  27
  28 Non-trivial patches should always be posted to guix-patches@gnu.org (trivial
  29 patches include fixing typos, etc.)  This mailing list fills the
  30 patch-tracking database at [[https://bugs.gnu.org/guix-patches]]; see
  31 "Contributing" in the manual for details.
  32
  33 For patches that just add a new package, and a simple one, it’s OK to commit,
  34 if you’re confident (which means you successfully built it in a chroot setup,
  35 and have done a reasonable copyright and license auditing.)  Likewise for
  36 package upgrades, except upgrades that trigger a lot of rebuilds (for example,
  37 upgrading GnuTLS or GLib.)  We have a mailing list for commit notifications
  38 (guix-commits@gnu.org), so people can notice.  Before pushing your changes,
  39 make sure to run ‘git pull --rebase’.
  40
  41 All commits that are pushed to the central repository on Savannah must be
  42 signed with an OpenPGP key, and the public key should be uploaded to your user
  43 account on Savannah and to public key servers, such as ‘pgp.mit.edu’.  To
  44 configure Git to automatically sign commits, run:
  45
  46   git config commit.gpgsign true
  47   git config user.signingkey CABBA6EA1DC0FF33
  48
  49 You can prevent yourself from accidentally pushing unsigned commits to Savannah
  50 by using the pre-push Git hook called 'pre-push'. It's located at
  51 'etc/git/pre-push'.
  52
  53 When pushing a commit on behalf of somebody else, please add a Signed-off-by
  54 line at the end of the commit log message (e.g. with ‘git am --signoff’).
  55 This improves tracking of who did what.
  56
  57 For anything else, please post to guix-patches@gnu.org and leave time for a
  58 review, without committing anything.  If you didn’t receive any reply
  59 after two weeks, and if you’re confident, it’s OK to commit.
  60
  61 That last part is subject to being adjusted, allowing individuals to commit
  62 directly on non-controversial changes on parts they’re familiar with.
