646# Features:
647# - bulk patch handling similar to epatch()'s
648# - automatic patch level detection like epatch()'s
649# - automatic patch uncompression like epatch()'s
650# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
651# manually instead
652# - once I decide it's production-ready, it'll be called from base_src_unpack
653# to handle $PATCHES to avoid defining src_unpack just to use xpatch

660# - because it doesn't use --dry-run there is a risk of it failing 742#
661# to find the files to patch, ie detect the patchlevel, properly. It doesn't use 743# make_desktop_entry(<binary>, [name], [icon], [type], [path])
662# any of the backup heuristics that patch employs to discover a filename. 744#
663# however, this isn't dangerous because if it works for the developer who's 745# binary: what binary does the app run with ?
664# writing the ebuild, it'll always work for the users, and if it doesn't, 746# name: the name that will show up in the menu

980#
981# Usage: unpack_pdv [file to unpack] [size of off_t]
982# - you have to specify the off_t size ... i have no idea how to extract that
983# information out of the binary executable myself. basically you pass in
984# the size of the off_t type (in bytes) on the machine that built the pdv
985# archive. one way to determine this is by running the following commands:
986# strings <pdv archive> | grep lseek
987# strace -elseek <pdv archive>
988# basically look for the first lseek command (we do the strings/grep because
989# sometimes the function call is _llseek or something) and steal the 2nd
990# parameter. here is an example:
991# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
992# lseek
993# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
994# lseek(3, -4, SEEK_END) = 2981250
995# thus we would pass in the value of '4' as the second parameter.
