658# @FUNCTION: epatch_user
659# @USAGE:
660# @DESCRIPTION:
661# Applies user-provided patches to the source tree. The patches are
662# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>[:SLOT]/, where the first
663# of these three directories to exist will be the one to use, ignoring
664# any more general directories which might exist as well. They must end
665# in ".patch" to be applied.
666#
667# User patches are intended for quick testing of patches without ebuild
668# modifications, as well as for permanent customizations a user might
669# desire. Obviously, there can be no official support for arbitrarily
670# patched ebuilds. So whenever a build log in a bug report mentions that
671# user patches were applied, the user should be asked to reproduce the
672# problem without these.
673#
674# Not all ebuilds do call this function, so placing patches in the
675# stated directory might or might not work, depending on the package and
676# the eclasses it inherits and uses. It is safe to call the function
677# repeatedly, so it is always possible to add a call at the ebuild
678# level. The first call is the time when the patches will be
679# applied.
680#
681# Ideally, this function should be called after gentoo-specific patches
682# have been applied, so that their code can be modified as well, but
683# before calls to e.g. eautoreconf, as the user patches might affect
684# autotool input files as well.

1211# Unpack those pesky pdv generated files ...
1212# They're self-unpacking programs with the binary package stuffed in
1213# the middle of the archive. Valve seems to use it a lot ... too bad
1214# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1215#
1216# You have to specify the off_t size ... I have no idea how to extract that
1217# information out of the binary executable myself. Basically you pass in
1218# the size of the off_t type (in bytes) on the machine that built the pdv
1219# archive.
1220#
1221# One way to determine this is by running the following commands:
1222#
1223# @CODE
1224# strings <pdv archive> | grep lseek
1225# strace -elseek <pdv archive>
1226# @CODE
1227#
1228# Basically look for the first lseek command (we do the strings/grep because
1229# sometimes the function call is _llseek or something) and steal the 2nd
1230# parameter. Here is an example:
1231#
1232# @CODE
1233# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1234# lseek
1235# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1236# lseek(3, -4, SEEK_END) = 2981250
1237# @CODE
1238#
1239# Thus we would pass in the value of '4' as the second parameter.

1464# the whole 'non-interactive' policy, but damnit I want CD support !
1465#
1466# With these cdrom functions we handle all the user interaction and
1467# standardize everything. All you have to do is call cdrom_get_cds()
1468# and when the function returns, you can assume that the cd has been
1469# found at CDROM_ROOT.
1470#
1471# The function will attempt to locate a cd based upon a file that is on
1472# the cd. The more files you give this function, the more cds
1473# the cdrom functions will handle.
1474#
1475# Normally the cdrom functions will refer to the cds as 'cd #1', 'cd #2',
1476# etc... If you want to give the cds better names, then just export
1477# the appropriate CDROM_NAME variable before calling cdrom_get_cds().
1478# Use CDROM_NAME for one cd, or CDROM_NAME_# for multiple cds. You can
1479# also use the CDROM_NAME_SET bash array.
