From cb08dd8b14bf4900c7974dd1ce5a3d553016585a Mon Sep 17 00:00:00 2001 From: Martin Fick Date: Tue, 25 Aug 2015 07:48:50 -0600 Subject: [PATCH] Add public isStaleFileHandle() API, improve detection. Add a public API to the FileUtils to determine if an IOException is a stale NFS file handle exception. This will make it easier to detect such errors, and interpret them consistently throughout the codebase. This new API is a bit more lenient in its detection than the previous detection, and should be able to detect some errors which previously were not identified as stale file handle exceptions because they had the word NFS in the error message. Adjust the packfile handling code to use this new API for detection.
