762# new convenience patch wrapper function to eventually replace epatch(), 762# for internal use only (unpack_pdv and unpack_makeself)
763# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and 763find_unpackable_file() {
764# /usr/bin/patch 764 local src="$1"
765# Features:
766# - bulk patch handling similar to epatch()'s
767# - automatic patch level detection like epatch()'s
768# - automatic patch uncompression like epatch()'s
769# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
770# manually instead
771# - once I decide it's production-ready, it'll be called from base_src_unpack
772# to handle $PATCHES to avoid defining src_unpack just to use xpatch
773
774# accepts zero or more parameters specifying patchfiles and/or patchdirs
775
776# known issues:
777# - only supports unified style patches (does anyone _really_ use anything
778# else?)
779# - because it doesn't use --dry-run there is a risk of it failing
780# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
781# any of the backup heuristics that patch employs to discover a filename.
782# however, this isn't dangerous because if it works for the developer who's
783# writing the ebuild, it'll always work for the users, and if it doesn't,
784# then we'll fix it :-)
785# - no support as yet for patches applying outside $S (and not directly in $WORKDIR).

784# Unpack those pesky pdv generated files ...
785# They're self-unpacking programs with the binary package stuffed in
786# the middle of the archive. Valve seems to use it a lot ... too bad
787# it seems to like to segfault a lot :(. So lets take it apart ourselves.
788#
789# Usage: unpack_pdv [file to unpack] [size of off_t]
790# - you have to specify the off_t size ... i have no idea how to extract that
791# information out of the binary executable myself. basically you pass in
792# the size of the off_t type (in bytes) on the machine that built the pdv
793# archive. one way to determine this is by running the following commands:
794# strings <pdv archive> | grep lseek
795# strace -elseek <pdv archive>
796# basically look for the first lseek command (we do the strings/grep because
797# sometimes the function call is _llseek or something) and steal the 2nd
798# parameter. here is an example:
799# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
800# lseek
801# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
802# lseek(3, -4, SEEK_END) = 2981250
803# thus we would pass in the value of '4' as the second parameter.
