#!/usr/bin/python3
# Given a merge proposal URL (eg.
# https://code.launchpad.net/~paelzer/ubuntu/+source/open-vm-tools/+git/open-vm-tools/+merge/352237)
# this script clones the proposer's branch, upload tags it, and pushes the
# upload tag to the official repository. This can be used by members of
# ~git-ubuntu-import to easily push an upload tag for contributors, until we
# have a mechanism to do this better.
#
# This does minimal checking. The target repository must be correct; otherwise
# the upload tag will be pushed to the wrong place. There are races (for
# example if the proposer pushes a new commit after you reviewed but before
# this script completes). However this script only pushes upload tags, so is
# generally safe since the importer always verifies before incorporating an
# upload tag. We intend to allow uploaders to push upload tags (or their
# equivalent) directly anyway; this is a stop-gap because using the current tag
# mechanism is awkward because Launchpad doesn't currently have per-ref ACLs.
#
# Prerequisites:
# python3-launchpadlib installed
# You have a Launchpad login that # belongs to ~git-ubuntu-import
