Subject: [PATCH v6 1/3] branch: accept multiple upstream branches for tracking
Date: Tue, 14 Dec 2021 15:44:54 -0800 [thread overview]
Message-ID: <43d6f83fedc022c44d6a3be249e7fd8cd2a25007.1639524556.git.steadmon@google.com> (raw)
In-Reply-To: <cover.1639524556.git.steadmon@google.com>
Add a new static variant of install_branch_config() that accepts
multiple remote branch names for tracking. This will be used in an
upcoming commit that enables inheriting the tracking configuration from
a parent branch.
Currently, all callers of install_branch_config() pass only a single
remote. Make install_branch_config() a small wrapper around
install_branch_config_multiple_remotes() so that existing callers do not
need to be changed.
