From bb571486ae93d02746c4bcc8032bde306f6d399a Mon Sep 17 00:00:00 2001 From: Allan Caffee Date: Sun, 31 Jul 2011 21:52:41 -0400 Subject: [PATCH] describe: Refresh the index when run with --dirty When running git describe --dirty the index should be refreshed. Previously the cached index would cause describe to think that the index was dirty when, in reality, it was just stale. The issue was exposed by python setuptools which hardlinks files into another directory when building a distribution.
