From 8cad84ccfbca7d9a3865c090e971c64700fd2ad5 Mon Sep 17 00:00:00 2001 From: Matthias Sohn Date: Sun, 27 Jan 2019 02:22:34 +0100 Subject: [PATCH] Fix GC.deleteEmptyRefsFolders This method tried to iterate spurious files which may exist in the .git/refs folder, e.g. on Mac a .DS_Store may have been created there by inspecting the folder using the finder application. This led to a NotDirectoryException when deleteEmptyRefsFolders tried to create an iterator for such a file entry. Skip files contained in the refs folder to ensure the method only tries to iterate contained folders but not files.
