Subject: [PATCH v4 02/11] connect: call get_host_and_port() earlier
Date: Tue, 3 May 2016 17:50:43 +0900 [thread overview]
Message-ID: <1462265452-32360-3-git-send-email-mh@glandium.org> (raw)
In-Reply-To: <1462265452-32360-1-git-send-email-mh@glandium.org>
Currently, get_host_and_port() is called in git_connect() for the ssh
protocol, and in git_tcp_connect_sock() for the git protocol. Instead
of doing this, just call it from a single place, right after
parse_connect_url(), and pass the host and port separately to
git_*_connect() functions.
We however preserve hostandport, at least for now.
Note that in git_tcp_connect_sock, the port was set to "<none>" in a
case that never can happen, so that code path was removed.
