715# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and 768find_unpackable_file() {
716# /usr/bin/patch
717# Features:
718# - bulk patch handling similar to epatch()'s
719# - automatic patch level detection like epatch()'s
720# - automatic patch uncompression like epatch()'s
721# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
722# manually instead
723# - once I decide it's production-ready, it'll be called from base_src_unpack
724# to handle $PATCHES to avoid defining src_unpack just to use xpatch
725
726# accepts zero or more parameters specifying patchfiles and/or patchdirs
727
728# known issues:
729# - only supports unified style patches (does anyone _really_ use anything
730# else?)
731# - because it doesn't use --dry-run there is a risk of it failing
732# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
733# any of the backup heuristics that patch employs to discover a filename.
734# however, this isn't dangerous because if it works for the developer who's
735# writing the ebuild, it'll always work for the users, and if it doesn't,
736# then we'll fix it :-)
737# - no support as yet for patches applying outside $S (and not directly in $WORKDIR).

789# Unpack those pesky pdv generated files ...
790# They're self-unpacking programs with the binary package stuffed in
791# the middle of the archive. Valve seems to use it a lot ... too bad
792# it seems to like to segfault a lot :(. So lets take it apart ourselves.
793#
794# Usage: unpack_pdv [file to unpack] [size of off_t]
795# - you have to specify the off_t size ... i have no idea how to extract that
796# information out of the binary executable myself. basically you pass in
797# the size of the off_t type (in bytes) on the machine that built the pdv
798# archive. one way to determine this is by running the following commands:
799# strings <pdv archive> | grep lseek
800# strace -elseek <pdv archive>
801# basically look for the first lseek command (we do the strings/grep because
802# sometimes the function call is _llseek or something) and steal the 2nd
803# parameter. here is an example:
804# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
805# lseek
806# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
807# lseek(3, -4, SEEK_END) = 2981250
808# thus we would pass in the value of '4' as the second parameter.
