Subject: [PATCH v3 4/6] bisect--helper: `bisect_reset` shell function in C
Date: Sun, 26 Jun 2016 17:53:54 +0530 [thread overview]
Message-ID: <20160626122356.28999-5-pranit.bauva@gmail.com> (raw)
In-Reply-To: <20160626122356.28999-1-pranit.bauva@gmail.com>
In-Reply-To: <20160607205454.22576-1-pranit.bauva@gmail.com>
Reimplement `bisect_reset` shell function in C and add a `--bisect-reset`
subcommand to `git bisect--helper` to call it from git-bisect.sh .
Using `bisect_reset` subcommand is a temporary measure to port shell
functions to C so as to use the existing test suite. As more functions
are ported, this subcommand would be retired and will be called by some
other method.
Note: --bisect-clean-state subcommand has not been retired as there are
still a function namely `bisect_start()` which still uses this
subcommand.
