Subject: [PATCH v2 07/11] bisect--helper: reimplement `bisect_autostart` shell function in C
Date: Sat, 21 Mar 2020 17:10:16 +0100 [thread overview]
Message-ID: <20200321161020.22817-8-mirucam@gmail.com> (raw)
In-Reply-To: <20200321161020.22817-1-mirucam@gmail.com>
From: Pranit Bauva <pranit.bauva@gmail.com>
Reimplement the `bisect_autostart()` shell function in C and add the
C implementation from `bisect_next()` which was previously left
uncovered. Also add a subcommand `--bisect-autostart` to
`git bisect--helper` be called from `bisect_state()` from
git-bisect.sh .
Using `--bisect-autostart` subcommand is a temporary measure to port
shell function to C so as to use the existing test suite. As more
functions are ported, this subcommand will be retired and
bisect_autostart() will be called directly by `bisect_state()`.
