Configuring Git
===============
This chapter describes maintainer level git configuration.
Tagged branches used in pull requests (see
Documentation/maintainer/pull-requests.rst) should be signed with the
developers public GPG key. Signed tags can be created by passing
``-u <key-id>`` to ``git tag``. However, since you would *usually* use the same
key for the project, you can set it in the configuration and use the ``-s``
flag. To set the default ``key-id`` use::
git config user.signingkey "keyname"
Alternatively, edit your ``.git/config`` or ``~/.gitconfig`` file by hand::
[user]
name = Jane Developer
email = jd@domain.org
signingkey = jd@domain.org
You may need to tell ``git`` to use ``gpg2``::
[gpg]
program = /path/to/gpg2
You may also like to tell ``gpg`` which ``tty`` to use (add to your shell
rc file)::
export GPG_TTY=$(tty)
Creating commit links to lore.kernel.org
----------------------------------------
The web site
https://lore.kernel.org is meant as a grand archive of all mail
list traffic concerning or influencing the kernel development. Storing archives
of patches here is a recommended practice, and when a maintainer applies a
patch to a subsystem tree, it is a good idea to provide a Link: tag with a
reference back to the lore archive so that people that browse the commit
history can find related discussions and rationale behind a certain change.
The link tag will look like this::
Link:
https://lore.kernel.org/r/<message-id>
This can be configured to happen automatically any time you issue ``git am``
by adding the following hook into your git::
$ git config am.messageid true
$ cat >.git/hooks/applypatch-msg <<'EOF'
#!/bin/sh
. git-sh-setup
perl -pi -e 's|^Message-I[dD]:\s*<?([^>]+)>?$|Link:
https://lore.kernel.org/r/$1|g;' "$1
"
test -x "$GIT_DIR/hooks/commit-msg" &&
exec "$GIT_DIR/hooks/commit-msg" ${1+"$@"}
:
EOF
$ chmod a+x .git/hooks/applypatch-msg
