Subject: [PATCH 2/4] clone: call git_config before parse_options
Date: Fri, 11 Sep 2020 18:25:25 +0000	[thread overview]
Message-ID: <51ef776f8523d29dfe03d15f0d1958f5c456c057.1599848727.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.727.git.1599848727.gitgitgadget@gmail.com>

From: Sean Barag <sean@barag.org>

While Junio's request [1] was to avoids the unusual  "write config then
immediately read it" pattern that exists in `cmd_clone`, Johannes
mentioned that --template can write new config values that aren't
automatically included in the environment [2]. This requires a config
re-read after `init_db` is called.

Moving the initial config up does allow settings from config to be
overwritten by ones provided via CLI options in a more natural way
though, so that part of Junio's suggestion remains.
