Subject: [PATCH v3 5/6] bisect--helper: `is_expected_rev` & `check_expected_revs` shell function in C
Date: Sun, 26 Jun 2016 17:53:55 +0530	[thread overview]
Message-ID: <20160626122356.28999-6-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 `is_expected_rev` & `check_expected_revs` shell function in
C and add a `--check-expected-revs` subcommand to `git bisect--helper` to
call it from git-bisect.sh .

Using `--check-expected-revs` 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.
