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

1232# @FUNCTION: unpack_pdv
1233# @USAGE: <file to unpack> <size of off_t>
1234# @DESCRIPTION:
1235# Unpack those pesky pdv generated files ...
1236# They're self-unpacking programs with the binary package stuffed in
1237# the middle of the archive. Valve seems to use it a lot ... too bad
1238# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1239#
1240# You have to specify the off_t size ... I have no idea how to extract that
1241# information out of the binary executable myself. Basically you pass in
1242# the size of the off_t type (in bytes) on the machine that built the pdv
1243# archive.
1244#
1245# One way to determine this is by running the following commands:
1246#
1247# @CODE
1248# strings <pdv archive> | grep lseek
1249# strace -elseek <pdv archive>
1250# @CODE
1251#
1252# Basically look for the first lseek command (we do the strings/grep because
1253# sometimes the function call is _llseek or something) and steal the 2nd
1254# parameter. Here is an example:
1255#
1256# @CODE
1257# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1258# lseek
1259# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1260# lseek(3, -4, SEEK_END) = 2981250
1261# @CODE
1262#
1263# Thus we would pass in the value of '4' as the second parameter.
