552# @FUNCTION: epatch_user
553# @USAGE:
554# @DESCRIPTION:
555# Applies user-provided patches to the source tree. The patches are
556# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
557# of these three directories to exist will be the one to use, ignoring
558# any more general directories which might exist as well. They must end
559# in ".patch" to be applied.
560#
561# User patches are intended for quick testing of patches without ebuild
562# modifications, as well as for permanent customizations a user might
563# desire. Obviously, there can be no official support for arbitrarily
564# patched ebuilds. So whenever a build log in a bug report mentions that
565# user patches were applied, the user should be asked to reproduce the
566# problem without these.
567#
568# Not all ebuilds do call this function, so placing patches in the
569# stated directory might or might not work, depending on the package and
570# the eclasses it inherits and uses. It is safe to call the function
571# repeatedly, so it is always possible to add a call at the ebuild
572# level. The first call is the time when the patches will be
573# applied.
574#
575# Ideally, this function should be called after gentoo-specific patches
576# have been applied, so that their code can be modified as well, but
577# before calls to e.g. eautoreconf, as the user patches might affect
578# autotool input files as well.

1223# Unpack those pesky pdv generated files ...
1224# They're self-unpacking programs with the binary package stuffed in
1225# the middle of the archive. Valve seems to use it a lot ... too bad
1226# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1227#
1228# You have to specify the off_t size ... I have no idea how to extract that
1229# information out of the binary executable myself. Basically you pass in
1230# the size of the off_t type (in bytes) on the machine that built the pdv
1231# archive.
1232#
1233# One way to determine this is by running the following commands:
1234#
1235# @CODE
1236# strings <pdv archive> | grep lseek
1237# strace -elseek <pdv archive>
1238# @CODE
1239#
1240# Basically look for the first lseek command (we do the strings/grep because
1241# sometimes the function call is _llseek or something) and steal the 2nd
1242# parameter. Here is an example:
1243#
1244# @CODE
1245# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1246# lseek
1247# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1248# lseek(3, -4, SEEK_END) = 2981250
1249# @CODE
1250#
1251# Thus we would pass in the value of '4' as the second parameter.
