Subject: [PATCH 8/8] ssh: 'simple' variant does not support --port
Date: Mon, 20 Nov 2017 13:31:01 -0800
Message-ID: <20171120213101.yquv2ywyjajjtr5x@aiede.mtv.corp.google.com> (raw)
In-Reply-To: <20171120212134.lh2l4drdzu6fh5g2@aiede.mtv.corp.google.com>

When trying to connect to an ssh:// URL with port explicitly specified
and the ssh command configured with GIT_SSH does not support such a
setting, it is less confusing to error out than to silently suppress
the port setting and continue.

This requires updating the GIT_SSH setting in t5603-clone-dirname.sh.
That test is about the directory name produced when cloning various
URLs.  It uses an ssh wrapper that ignores all its arguments but does
not declare that it supports a port argument; update it to set
GIT_SSH_VARIANT=ssh to do so.  (Real-life ssh wrappers that pass a
port argument to OpenSSH would also support -G and would not require
such an update.)

As before.

That's the end of the series.  Thanks for reading.
