File gcei-handle-missing-gsutil.patch of Package google-compute-engine-init.3436
From 6dfc6c00613fb2d5e51f13fa77d5258188489732 Mon Sep 17 00:00:00 2001 From: Robert Schweikert <rjschwei@suse.com> Date: Fri, 14 Oct 2016 12:16:35 -0400 Subject: [PATCH] - Check for existence of external executable + With the check we can exit early and provide a message to the user that the executable is missing, rather than having the information about the missing executable intermingled with a failed call thereof. Last but not least it avoids the message that indicates that a download is being attempted, which could lead to confusion. --- google_compute_engine/metadata_scripts/script_retriever.py | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/google_compute_engine/metadata_scripts/script_retriever.py b/google_compute_engine/metadata_scripts/script_retriever.py index a5c77a5..0625b0a 100644 --- a/google_compute_engine/metadata_scripts/script_retriever.py +++ b/google_compute_engine/metadata_scripts/script_retriever.py @@ -50,6 +50,18 @@ class ScriptRetriever(object): Returns: string, the path to the file storing the metadata script.
