8# @BLURB: many extra (but common) functions that are used in ebuilds
9# @DESCRIPTION:
10# The eutils eclass contains a suite of functions that complement
11# the ones that ebuild.sh already contain. The idea is that the functions
12# are not required in all ebuilds but enough utilize them to have a common
13# home rather than having multiple ebuilds implementing the same thing.
14#
15# Due to the nature of this eclass, some functions may have maintainers
16# different from the overall eclass!

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

142# This function is for bulk patching, or in theory for just one 259# @FUNCTION: epatch
143# 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.
144# 267#
145# 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
146# Currently all patches should be the same format. 269# specified by EPATCH_SOURCE.
147# 270#
148# You do not have to specify '-p' option to patch, as it will 271# When processing directories, epatch will apply all patches that match:
149# try with -p0 to -p5 until it succeed, or fail at -p5. 272# @CODE
150# 273# if ${EPATCH_FORCE} != "yes"
151# Above EPATCH_* variables can be used to control various defaults,
152# bug they should be left as is to ensure an ebuild can rely on
153# them for.
154#
155# Patches are applied in current directory.
156#
157# Bulk Patches should preferibly have the form of:
158#
159# ??_${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.
160# 283#
161# For example: 284# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
285# for patches to apply.
162# 286#
163# 01_all_misc-fix.patch.bz2 287# Refer to the other EPATCH_xxx variables for more customization of behavior.
164# 02_sparc_another-fix.patch.bz2
165#
166# This ensures that there are a set order, and you can have ARCH
167# specific patches.
168#
169# If you however give an argument to epatch(), it will treat it as a
170# single patch that need to be applied if its a file. If on the other
171# hand its a directory, it will set EPATCH_SOURCE to this.

911# it seems to like to segfault a lot :(. So lets take it apart ourselves.
912#
913# Usage: unpack_pdv [file to unpack] [size of off_t]
914# - you have to specify the off_t size ... i have no idea how to extract that
915# information out of the binary executable myself. basically you pass in
916# the size of the off_t type (in bytes) on the machine that built the pdv
917# archive. one way to determine this is by running the following commands:
918# strings <pdv archive> | grep lseek
919# strace -elseek <pdv archive>
920# basically look for the first lseek command (we do the strings/grep because
921# sometimes the function call is _llseek or something) and steal the 2nd
922# parameter. here is an example:
923# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
924# lseek
925# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
926# lseek(3, -4, SEEK_END) = 2981250
927# thus we would pass in the value of '4' as the second parameter.
