Subject: [PATCH v9 5/5] bisect: allow any terms set by user
Date: Thu, 25 Jun 2015 20:50:57 +0200 [thread overview]
Message-ID: <1435258257-29047-6-git-send-email-Matthieu.Moy@imag.fr> (raw)
In-Reply-To: <1435258257-29047-1-git-send-email-Matthieu.Moy@imag.fr>
From: Antoine Delaite <antoine.delaite@ensimag.grenoble-inp.fr>
Introduction of the git bisect terms command. The user can set his own
terms. It will work exactly like before. The terms must be set before the
start.

`git bisect new <rev>`/`git bisect old <rev>...` after to add the
commits.
+Alternative terms: use your own terms
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If the builtins terms bad/good and new/old do not satisfy you, you can
+set your own terms.
+
+------------------------------------------------
+git bisect terms <term-new> <term-old>
+------------------------------------------------
+
+This command has to be used before a bisection has started. <term-old>
+must be associated with the latest revisions and <term-new> with the
+ancestors of <term-old>. For example, if something was buggy in the
+old part of the history, you know somewhere the bug was fixed, and you
+want to find the exact commit that fixed it, you may want to say `git
+bisect terms fixed broken`; this way, you would mark a commit that
+still has the bug with `broken`, and a newer one after the fix with
+`fixed`.
+
+Only the first bisection following the `git bisect terms` will use the
+terms. If you mistyped one of the terms you can do again `git bisect
+terms <term-old> <term-new>`.
