155# This is meant for variables where using `local` does not work (such as

220# @FUNCTION: eshopts_push
221# @USAGE: [options to `set` or `shopt`]
222# @DESCRIPTION:
223# Often times code will want to enable a shell option to change code behavior.
224# Since changing shell options can easily break other pieces of code (which
225# assume the default state), eshopts_push is used to (1) push the current shell
226# options onto a stack and (2) pass the specified arguments to set.
227#
228# If the first argument is '-s' or '-u', we assume you want to call `shopt`
229# rather than `set` as there are some options only available via that.
230#
231# A common example is to disable shell globbing so that special meaning/care
232# may be used with variables/arguments to custom functions. That would be:
233# @CODE
234# eshopts_push -s noglob
235# for x in ${foo} ; do
236# if ...some check... ; then
237# eshopts_pop
238# return 0

95# This function is for bulk patching, or in theory for just one 353# @FUNCTION: epatch
96# or two patches. 354# @USAGE: [options] [patches] [dirs of patches]
355# @DESCRIPTION:
356# epatch is designed to greatly simplify the application of patches. It can
357# process patch files directly, or directories of patches. The patches may be
358# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
359# the -p option as epatch will automatically attempt -p0 to -p4 until things
360# apply successfully.
97# 361#
98# It should work with .bz2, .gz, .zip and plain text patches. 362# If you do not specify any patches/dirs, then epatch will default to the
99# Currently all patches should be the same format. 363# directory specified by EPATCH_SOURCE.
100# 364#
101# You do not have to specify '-p' option to patch, as it will 365# Any options specified that start with a dash will be passed down to patch
102# try with -p0 to -p5 until it succeed, or fail at -p5. 366# for this specific invocation. As soon as an arg w/out a dash is found, then
367# arg processing stops.
103# 368#
104# Above EPATCH_* variables can be used to control various defaults, 369# When processing directories, epatch will apply all patches that match:
105# bug they should be left as is to ensure an ebuild can rely on 370# @CODE
106# them for. 371# if ${EPATCH_FORCE} != "yes"
107#
108# Patches are applied in current directory.
109#
110# Bulk Patches should preferibly have the form of:
111#
112# ??_${ARCH}_foo.${EPATCH_SUFFIX} 372# ??_${ARCH}_foo.${EPATCH_SUFFIX}
373# else
374# *.${EPATCH_SUFFIX}
375# @CODE
376# The leading ?? are typically numbers used to force consistent patch ordering.
377# The arch field is used to apply patches only for the host architecture with
378# the special value of "all" means apply for everyone. Note that using values
379# other than "all" is highly discouraged -- you should apply patches all the
380# time and let architecture details be detected at configure/compile time.
113# 381#
114# For example: 382# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
383# for patches to apply.
115# 384#
116# 01_all_misc-fix.patch.bz2 385# Refer to the other EPATCH_xxx variables for more customization of behavior.
117# 02_sparc_another-fix.patch.bz2
118#
119# This ensures that there are a set order, and you can have ARCH
120# specific patches.
121#
122# If you however give an argument to epatch(), it will treat it as a
123# single patch that need to be applied if its a file. If on the other
124# hand its a directory, it will set EPATCH_SOURCE to this.

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.

1079# Unpack those pesky pdv generated files ...
1080# They're self-unpacking programs with the binary package stuffed in
1081# the middle of the archive. Valve seems to use it a lot ... too bad
1082# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1083#
1084# You have to specify the off_t size ... I have no idea how to extract that
1085# information out of the binary executable myself. Basically you pass in
1086# the size of the off_t type (in bytes) on the machine that built the pdv
1087# archive.
1088#
1089# One way to determine this is by running the following commands:
1090#
1091# @CODE
1092# strings <pdv archive> | grep lseek
1093# strace -elseek <pdv archive>
1094# @CODE
1095#
1096# Basically look for the first lseek command (we do the strings/grep because
1097# sometimes the function call is _llseek or something) and steal the 2nd
1098# parameter. Here is an example:
1099#
1100# @CODE
1101# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1102# lseek
1103# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1104# lseek(3, -4, SEEK_END) = 2981250
1105# @CODE
1106#
1107# Thus we would pass in the value of '4' as the second parameter.
