8# @BLURB: many extra (but common) functions that are used in ebuilds
9# @DESCRIPTION:
10# The eutils eclass contains a suite of functions that complement
11# the ones that ebuild.sh already contain. The idea is that the functions
12# are not required in all ebuilds but enough utilize them to have a common
13# home rather than having multiple ebuilds implementing the same thing.
14#
15# Due to the nature of this eclass, some functions may have maintainers
16# different from the overall eclass!

728# new convenience patch wrapper function to eventually replace epatch(),
729# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and
730# /usr/bin/patch
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 :-)
751# - no support as yet for patches applying outside $S (and not directly in $WORKDIR).

1130# @DESCRIPTION:
1131# Unpack those pesky pdv generated files ...
1132# They're self-unpacking programs with the binary package stuffed in
1133# the middle of the archive. Valve seems to use it a lot ... too bad
1134# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1135#
1136# You have to specify the off_t size ... I have no idea how to extract that
1137# information out of the binary executable myself. Basically you pass in
1138# the size of the off_t type (in bytes) on the machine that built the pdv
1139# archive.
1140#
1141# One way to determine this is by running the following commands:
1142#
1143# @CODE
1144# strings <pdv archive> | grep lseek
1145# strace -elseek <pdv archive>
1146# @CODE
1147#
1148# Basically look for the first lseek command (we do the strings/grep because
1149# sometimes the function call is _llseek or something) and steal the 2nd
1150# parameter. Here is an example:
1151#
1152# @CODE
1153# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1154# lseek
1155# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1156# lseek(3, -4, SEEK_END) = 2981250
1157# @CODE
1158#
1159# Thus we would pass in the value of '4' as the second parameter.
