The previous recommendation, running ‘make authenticate’, was insecure because it led users to run code from the very repository they want to authenticate: https://lists.gnu.org/archive/html/guix-devel/2024-04/msg00252.html * Makefile.am (commit_v1_0_0, channel_intro_commit) (channel_intro_signer, GUIX_GIT_KEYRING, authenticate): Remove. * Makefile.am (.git/hooks/%): New target, generalization of previous ‘.git/hooks/pre-push’ target. (nodist_noinst_DATA): Add ‘.git/hooks/post-merge’. * doc/contributing.texi (Building from Git): Suggest ‘guix git authenticate’ instead of ‘make authenticate’. * etc/git/post-merge: New file. * etc/git/pre-push: Run ‘guix git authenticate’ instead of ‘make authenticate’.

# This hook script prevents the user from pushing to Savannah if any of the new
|
|
# commits' OpenPGP signatures cannot be verified, or if a commit is signed
|
|
# with an unauthorized key.

# Called by "git push" after it has checked the remote status, but before
|
|
# anything has been pushed. If this script exits with a non-zero status nothing
|
|
# will be pushed.
|
|
#
|
|
# This hook is called with the following parameters:
|
|
#
|
|
# $1 -- Name of the remote to which the push is being done
|
|
# $2 -- URL to which the push is being done
|
|
#
|
|
# If pushing without using a named remote those arguments will be equal.
|
|
#
|
|
# Information about the commits which are being pushed is supplied as lines to
|
|
# the standard input in the form:
|
|
#
|
|
# <local ref> <local sha1> <remote ref> <remote sha1>
|
|
|
|
# This is the "empty hash" used by Git when pushing a branch deletion.
