Subject: [PATCH 3/9] vcs-svn: simplify cleanup in apply_one_window
Date: Fri, 6 Jul 2012 12:18:00 -0500 [thread overview]
Message-ID: <20120706171759.GD31001@burratino> (raw)
In-Reply-To: <20120706171040.GA31001@burratino>
From: David Barr <davidbarr@google.com>

Currently the cleanup code looks like this:
free resources
return 0;
error_out:
free resources
return -1;
Avoid duplicating the "free resources" part by keeping the return
value in a variable and sharing code between the success and
exceptional case:
ret = 0;
out:
free resources
return ret;
Noticed in the svn-dump-fast-export project, where using the error()
macro in void context produces a warning.
