From f182ebc11c9ea7a5bf75e35d8e061f3ac68482fd Mon Sep 17 00:00:00 2001 From: Matt Farina Date: Fri, 22 May 2020 12:04:37 -0400 Subject: [PATCH] Fix issue with unhandled error on Stat If stat returns an error other than the directory not existing it was unhandled. When IsDir is called in one of these situations it causes a panic.
