Subject: [PATCH v2 1/9] config: introduce set_or_die wrappers
Date: Thu, 28 Jan 2016 10:00:29 +0100	[thread overview]
Message-ID: <1453971637-22273-2-git-send-email-ps@pks.im> (raw)
In-Reply-To: <1453971637-22273-1-git-send-email-ps@pks.im>

A lot of call-sites for the existing family of `git_config_set`
functions do not check for errors that may occur, e.g. the
configuration file being locked. In many cases we simply want to
die when such a situation arises.

Introduce wrappers that will cause the program to die in those
cases.
