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

74# This function is for bulk patching, or in theory for just one 259# @FUNCTION: epatch
75# or two patches. 260# @USAGE: [patches] [dirs of patches]
261# @DESCRIPTION:
262# epatch is designed to greatly simplify the application of patches. It can
263# process patch files directly, or directories of patches. The patches may be
264# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
265# the -p option as epatch will automatically attempt -p0 to -p5 until things
266# apply successfully.
76# 267#
77# It should work with .bz2, .gz, .zip and plain text patches. 268# If you do not specify any options, then epatch will default to the directory
78# Currently all patches should be the same format. 269# specified by EPATCH_SOURCE.
79# 270#
80# You do not have to specify '-p' option to patch, as it will 271# When processing directories, epatch will apply all patches that match:
81# try with -p0 to -p5 until it succeed, or fail at -p5. 272# @CODE
82# 273# if ${EPATCH_FORCE} != "yes"
83# Above EPATCH_* variables can be used to control various defaults,
84# bug they should be left as is to ensure an ebuild can rely on
85# them for.
86#
87# Patches are applied in current directory.
88#
89# Bulk Patches should preferibly have the form of:
90#
91# ??_${ARCH}_foo.${EPATCH_SUFFIX} 274# ??_${ARCH}_foo.${EPATCH_SUFFIX}
275# else
276# *.${EPATCH_SUFFIX}
277# @CODE
278# The leading ?? are typically numbers used to force consistent patch ordering.
279# The arch field is used to apply patches only for the host architecture with
280# the special value of "all" means apply for everyone. Note that using values
281# other than "all" is highly discouraged -- you should apply patches all the
282# time and let architecture details be detected at configure/compile time.
92# 283#
93# For example: 284# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
285# for patches to apply.
94# 286#
95# 01_all_misc-fix.patch.bz2 287# 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.

524# @FUNCTION: epatch_user
525# @USAGE:
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.

1058# the middle of the archive. Valve seems to use it a lot ... too bad
1059# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1060#
1061# You have to specify the off_t size ... I have no idea how to extract that

1063# the size of the off_t type (in bytes) on the machine that built the pdv
1064# archive.
1065#
1066# One way to determine this is by running the following commands:
1067# strings <pdv archive> | grep lseek
1068# strace -elseek <pdv archive>
1069# Basically look for the first lseek command (we do the strings/grep because
1070# sometimes the function call is _llseek or something) and steal the 2nd
1071# parameter. Here is an example:
1072# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1073# lseek
1074# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
