518# of these three directories to exist will be the one to use, ignoring
519# any more general directories which might exist as well.
520#
521# User patches are intended for quick testing of patches without ebuild
522# modifications, as well as for permanent customizations a user might
523# desire. Obviously, there can be no official support for arbitrarily
524# patched ebuilds. So whenever a build log in a bug report mentions that
525# user patches were applied, the user should be asked to reproduce the
526# problem without these.
527#
528# Not all ebuilds do call this function, so placing patches in the
529# stated directory might or might not work, depending on the package and
530# the eclasses it inherits and uses. It is safe to call the function
531# repeatedly, so it is always possible to add a call at the ebuild
532# level. The first call is the time when the patches will be
533# applied.
534#
535# Ideally, this function should be called after gentoo-specific patches
536# have been applied, so that their code can be modified as well, but
537# before calls to e.g. eautoreconf, as the user patches might affect

1205# @USAGE: <file to unpack> <size of off_t>
1206# @DESCRIPTION:
1207# Unpack those pesky pdv generated files ...
1208# They're self-unpacking programs with the binary package stuffed in
1209# the middle of the archive. Valve seems to use it a lot ... too bad
1210# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1211#
1212# You have to specify the off_t size ... I have no idea how to extract that
1213# information out of the binary executable myself. Basically you pass in
1214# the size of the off_t type (in bytes) on the machine that built the pdv
1215# archive.
1216#
1217# One way to determine this is by running the following commands:
1218#
1219# @CODE
1220# strings <pdv archive> | grep lseek
1221# strace -elseek <pdv archive>
1222# @CODE
1223#
1224# Basically look for the first lseek command (we do the strings/grep because
1225# sometimes the function call is _llseek or something) and steal the 2nd
1226# parameter. Here is an example:
1227#
1228# @CODE
1229# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1230# lseek
1231# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1232# lseek(3, -4, SEEK_END) = 2981250
1233# @CODE
1234#
1235# Thus we would pass in the value of '4' as the second parameter.
