Subject: [PATCH 3/4] clone: validate --origin option before use
Date: Fri, 11 Sep 2020 18:25:26 +0000 [thread overview]
Message-ID: <0dff8cd66930130ffd5f0d7d068ad3ed47cd1c81.1599848727.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.727.git.1599848727.gitgitgadget@gmail.com>
From: Sean Barag <sean@barag.org>
Providing a bad origin name to `git clone` currently reports an
'invalid refspec' error instead of a more explicit message explaining
that the `--origin` option was malformed. Per Junio, it's been this way
since 8434c2f1 (Build in clone, 2008-04-27). This patch reintroduces
validation for the provided `--origin` option, but notably _doesn't_
include a multi-level check (e.g. "foo/bar") that was present in the
original `git-clone.sh`. It seems `git remote` allows multi-level
remote names, so applying that same validation in `git clone` seems
reasonable.

Thanks-to: Junio C Hamano <gitster@pobox.com>
