Subject: [PATCH 20/26] bisect--helper: `bisect_replay` shell function in C
Date: Sun, 24 Feb 2019 02:11:30 -0800 (PST) [thread overview]
Message-ID: <1e9034bb9de0e44be8ecfcc27ebc97d0dd4b44fd.1551003074.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.117.git.gitgitgadget@gmail.com>
From: Pranit Bauva <pranit.bauva@gmail.com>
Reimplement the `bisect_replay` shell function in C and also add
`--bisect-replay` subcommand to `git bisect--helper` to call it from
git-bisect.sh
Using `--bisect-replay` 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 will be called by some
other method.
