Subject: [dpdk-ci] [PATCH v2 4/4] guess_git_tree: fix crash caused by empty diff
Date: Wed, 13 Oct 2021 10:00:10 -0400
Message-ID: <20211013140010.25400-4-ohilyard@iol.unh.edu> (raw)
In-Reply-To: <20211013140010.25400-1-ohilyard@iol.unh.edu>

From: Owen Hilyard <ohilyard@iol.unh.edu>

A sanity check has been added to find_filenames. Occasionally, due to
how the community lab internally handles getting patches from
patchworks, a patch will result in no diff. This patch adds handling for
this case.
