151# @FUNCTION: eshopts_push
152# @USAGE: [options to `set` or `shopt`]
153# @DESCRIPTION:
154# Often times code will want to enable a shell option to change code behavior.
155# Since changing shell options can easily break other pieces of code (which
156# assume the default state), eshopts_push is used to (1) push the current shell
157# options onto a stack and (2) pass the specified arguments to set.
158#
159# If the first argument is '-s' or '-u', we assume you want to call `shopt`
160# rather than `set` as there are some options only available via that.
161#
162# A common example is to disable shell globbing so that special meaning/care
163# may be used with variables/arguments to custom functions. That would be:
164# @CODE
165# eshopts_push -s noglob
166# for x in ${foo} ; do
167# if ...some check... ; then
168# eshopts_pop
169# return 0
170# fi

74# This function is for bulk patching, or in theory for just one 267# @FUNCTION: epatch
75# or two patches. 268# @USAGE: [options] [patches] [dirs of patches]
269# @DESCRIPTION:
270# epatch is designed to greatly simplify the application of patches. It can
271# process patch files directly, or directories of patches. The patches may be
272# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
273# the -p option as epatch will automatically attempt -p0 to -p5 until things
274# apply successfully.
76# 275#
77# It should work with .bz2, .gz, .zip and plain text patches. 276# If you do not specify any patches/dirs, then epatch will default to the
78# Currently all patches should be the same format. 277# directory specified by EPATCH_SOURCE.
79# 278#
80# You do not have to specify '-p' option to patch, as it will 279# Any options specified that start with a dash will be passed down to patch
81# try with -p0 to -p5 until it succeed, or fail at -p5. 280# for this specific invocation. As soon as an arg w/out a dash is found, then
281# arg processing stops.
82# 282#
83# Above EPATCH_* variables can be used to control various defaults, 283# When processing directories, epatch will apply all patches that match:
84# bug they should be left as is to ensure an ebuild can rely on 284# @CODE
85# them for. 285# if ${EPATCH_FORCE} != "yes"
86#
87# Patches are applied in current directory.
88#
89# Bulk Patches should preferibly have the form of:
90#
91# ??_${ARCH}_foo.${EPATCH_SUFFIX} 286# ??_${ARCH}_foo.${EPATCH_SUFFIX}
287# else
288# *.${EPATCH_SUFFIX}
289# @CODE
290# The leading ?? are typically numbers used to force consistent patch ordering.
291# The arch field is used to apply patches only for the host architecture with
292# the special value of "all" means apply for everyone. Note that using values
293# other than "all" is highly discouraged -- you should apply patches all the
294# time and let architecture details be detected at configure/compile time.
92# 295#
93# For example: 296# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
297# for patches to apply.
94# 298#
95# 01_all_misc-fix.patch.bz2 299# Refer to the other EPATCH_xxx variables for more customization of behavior.
96# 02_sparc_another-fix.patch.bz2
97#
98# This ensures that there are a set order, and you can have ARCH
99# specific patches.
100#
101# If you however give an argument to epatch(), it will treat it as a
102# single patch that need to be applied if its a file. If on the other
103# hand its a directory, it will set EPATCH_SOURCE to this.

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

1061# They're self-unpacking programs with the binary package stuffed in
1062# the middle of the archive. Valve seems to use it a lot ... too bad
1063# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1064#
1065# You have to specify the off_t size ... I have no idea how to extract that
1066# information out of the binary executable myself. Basically you pass in
1067# the size of the off_t type (in bytes) on the machine that built the pdv

1069#
1070# One way to determine this is by running the following commands:

1073# strings <pdv archive> | grep lseek
1074# strace -elseek <pdv archive>
1075# @CODE

1078# sometimes the function call is _llseek or something) and steal the 2nd
1079# parameter. Here is an example:
1080#
1081# @CODE
1082# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1083# lseek
1084# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1085# lseek(3, -4, SEEK_END) = 2981250
1086# @CODE
