731# Features:
732# - bulk patch handling similar to epatch()'s
733# - automatic patch level detection like epatch()'s
734# - automatic patch uncompression like epatch()'s
735# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
736# manually instead
737# - once I decide it's production-ready, it'll be called from base_src_unpack
738# to handle $PATCHES to avoid defining src_unpack just to use xpatch
739
740# accepts zero or more parameters specifying patchfiles and/or patchdirs
741
742# known issues:
743# - only supports unified style patches (does anyone _really_ use anything
744# else?)
745# - because it doesn't use --dry-run there is a risk of it failing
746# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
747# any of the backup heuristics that patch employs to discover a filename.
748# however, this isn't dangerous because if it works for the developer who's
749# writing the ebuild, it'll always work for the users, and if it doesn't,
750# then we'll fix it :-)

798#
799# Usage: unpack_pdv [file to unpack] [size of off_t]
800# - you have to specify the off_t size ... i have no idea how to extract that
801# information out of the binary executable myself. basically you pass in
802# the size of the off_t type (in bytes) on the machine that built the pdv
803# archive. one way to determine this is by running the following commands:
804# strings <pdv archive> | grep lseek
805# strace -elseek <pdv archive>
806# basically look for the first lseek command (we do the strings/grep because
807# sometimes the function call is _llseek or something) and steal the 2nd
808# parameter. here is an example:
809# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
810# lseek
811# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
812# lseek(3, -4, SEEK_END) = 2981250
813# thus we would pass in the value of '4' as the second parameter.
