Subject: [GSoC][PATCH v4 3/3] rebase -i: rewrite setup_reflog_action() in C
Date: Mon, 25 Jun 2018 15:44:19 +0200 [thread overview]
Message-ID: <20180625134419.18435-4-alban.gruin@gmail.com> (raw)
In-Reply-To: <20180625134419.18435-1-alban.gruin@gmail.com>
This rewrites (the misnamed) setup_reflog_action() from shell to C. The
new version is called checkout_onto().
A new command is added to rebase--helper.c, “checkout-base”. The shell
version is then stripped.
As $GIT_REFLOG_ACTION is no longer set at the first call of
checkout_onto(), a call to comment_for_reflog() is added at the
beginning of this function.
If the commit OID provided to checkout_onto() is empty, nothing happens
and no errors are returned, otherwise it would break some
tests (t3404.92 and t3404.93).
