- exec -a "$0" so git.real sees the correct argv[0] (e.g. git-upload-pack) and dispatches correctly; without this SSH clone was broken - Check only $1 for "merge-file" instead of scanning all args, preventing accidental ifcmerge invocation from commit messages or other arg positions - Use absolute path /usr/local/bin/ifcmerge to prevent PATH hijacking Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# Forgejo checks PR mergeability by calling 'git merge-file current base other'
|
|
# directly. This bypasses gitattributes merge drivers entirely — there is no
|
|
# way to configure ifcmerge via /etc/gitconfig for this code path.
|
|
#
|
|
# This wrapper intercepts 'git merge-file' calls where the file being merged
|
|
# is an IFC/STEP file (identified by the ISO-10303 header) and delegates to
|
|
# ifcmerge instead of git's built-in text merge.
|
|
#
|
|
# Installation:
|
|
# mv /usr/bin/git /usr/bin/git.real
|
|
# cp git-wrapper /usr/bin/git
|
|
# chmod +x /usr/bin/git
|
|
#
|
|
# The wrapper is transparent for all other git commands.
|
|
#
|
|
# NOTE: apt upgrades to the git package will overwrite /usr/bin/git.
|
|
# After any git package upgrade, reinstall this wrapper.
