From bf39e1548cf4dc4642803da931e69b56365fe1b1 Mon Sep 17 00:00:00 2001 From: P. J. McDermott Date: Wed, 19 Jun 2013 08:27:38 -0400 Subject: Fuzz is fatal. Update indentation in patch. Apparently, some indentation changed between versions 4.7.2 and 4.7.3 of GCC. BusyBox patch "does not use the location information, but instead treats a hunk as a sort of regex" (BusyBox 1.21.0 editors/patch.c:209). It ignores line numbers and relies on context matching to find hunks to patch. Therefore, changes to the context in the original file cause BusyBox patch to fail to apply a hunk. Fuzz is fatal. A patch needs to be refreshed when a new upstream version modifies its context.
