Revision 8ed0a740dd42bd0724aebed6e3b07c4ea2a2d5e8 authored by Matt McCutchen on 17 October 2008, 02:32:14 UTC, committed by Junio C Hamano on 17 October 2008, 02:37:27 UTC
This test creates files with several different umasks and expects their permissions to be initialized according to the umask, so a default ACL on the trash directory (which overrides the umask for files created in that directory) causes the test to fail. To avoid that, remove the default ACL if possible with setfacl(1). Signed-off-by: Matt McCutchen <matt@mattmccutchen.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
