From 199722a65a88f9c28b554b180ec36415ed3a51ac Mon Sep 17 00:00:00 2001 From: Dan Smith Date: Wed, 9 Nov 2022 07:33:37 -0800 Subject: [PATCH] Fix unintentional exception inspecting VMDK It looks like a raise statement was left in the virtual_size property handler for VMDK, which should have been converted to a log at some point. All the other inspectors return zero for virtual_size if the format does not match or they are unable to parse the data. This converts that raise to a log, and adds a test to make sure we make it far enough in the processing of the complex VMDK format to ensure that behavior.
