Subject: [PATCH 06/15] pretty: limit recursion in format_commit_one()
Date: Tue, 9 Jul 2013 16:02:17 +0530 [thread overview]
Message-ID: <1373365946-9230-7-git-send-email-artagnon@gmail.com> (raw)
In-Reply-To: <1373365946-9230-1-git-send-email-artagnon@gmail.com>
To make sure that a pretty_ctx->format substitution doesn't result in an
infinite recursion, change the prototype of format_commit_one() to
accept one last argument: no_recurse. So, a single substitution by
format() must yield a result that can be parsed by format_commit_one()
without the help of format().
