Subject: [PATCH v10 5/7] bisect: simplify the addition of new bisect terms
Date: Fri, 26 Jun 2015 18:58:14 +0200 [thread overview]
Message-ID: <1435337896-20709-6-git-send-email-Matthieu.Moy@imag.fr> (raw)
In-Reply-To: <1435337896-20709-1-git-send-email-Matthieu.Moy@imag.fr>
From: Antoine Delaite <antoine.delaite@ensimag.grenoble-inp.fr>
We create a file BISECT_TERMS in the repository .git to be read during a
bisection. The fonctions to be changed if we add new terms are quite
few.
In git-bisect.sh :
check_and_set_terms
bisect_voc
