From 13b281d74380d9622574bd546e7f9084054ae289 Mon Sep 17 00:00:00 2001 From: Xavier Chantry Date: Fri, 22 May 2009 00:24:26 +0200 Subject: xdelta : only handle gz compression specifically There is apparently no need to handle the re-compression manually when applying a xdelta patch in case of bzip2 or xz. Only gzip needs to be handled specifically for disabling timestamp with the -n option. After this patch, if xdelta is enhanced with xz support (1-line patch), it will be transparent from pacman side.
