524# @FUNCTION: epatch_user

526# @DESCRIPTION:
527# Applies user-provided patches to the source tree. The patches are
528# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
529# of these three directories to exist will be the one to use, ignoring
530# any more general directories which might exist as well. They must end
531# in ".patch" to be applied.
532#
533# User patches are intended for quick testing of patches without ebuild
534# modifications, as well as for permanent customizations a user might
535# desire. Obviously, there can be no official support for arbitrarily
536# patched ebuilds. So whenever a build log in a bug report mentions that
537# user patches were applied, the user should be asked to reproduce the
538# problem without these.
539#
540# Not all ebuilds do call this function, so placing patches in the
541# stated directory might or might not work, depending on the package and
542# the eclasses it inherits and uses. It is safe to call the function
543# repeatedly, so it is always possible to add a call at the ebuild
544# level. The first call is the time when the patches will be
545# applied.
546#
547# Ideally, this function should be called after gentoo-specific patches
548# have been applied, so that their code can be modified as well, but
549# before calls to e.g. eautoreconf, as the user patches might affect
550# autotool input files as well.

1193# Unpack those pesky pdv generated files ...
1194# They're self-unpacking programs with the binary package stuffed in
1195# the middle of the archive. Valve seems to use it a lot ... too bad
1196# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1197#
1198# You have to specify the off_t size ... I have no idea how to extract that
1199# information out of the binary executable myself. Basically you pass in
1200# the size of the off_t type (in bytes) on the machine that built the pdv
1201# archive.
1202#
1203# One way to determine this is by running the following commands:
1204#
1205# @CODE
1206# strings <pdv archive> | grep lseek
1207# strace -elseek <pdv archive>
1208# @CODE
1209#
1210# Basically look for the first lseek command (we do the strings/grep because
1211# sometimes the function call is _llseek or something) and steal the 2nd
1212# parameter. Here is an example:
1213#
1214# @CODE
1215# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1216# lseek
1217# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1218# lseek(3, -4, SEEK_END) = 2981250
1219# @CODE
1220#
1221# Thus we would pass in the value of '4' as the second parameter.
