Subject: [GSoC][PATCH v4 1/3] sequencer: extract a function to silence a command, except if it fails
Date: Mon, 25 Jun 2018 15:44:17 +0200 [thread overview]
Message-ID: <20180625134419.18435-2-alban.gruin@gmail.com> (raw)
In-Reply-To: <20180625134419.18435-1-alban.gruin@gmail.com>
This extracts the part of run_git_commit() that redirects the stdout and
stderr of a command to a strbuf, and prints it if the command fails, to
a helper function: run_command_silent_on_success(). It is intended to
replace output() from git-rebase.sh in the rewrite of
setup_reflog_action() and checkout_onto().
