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!

83# example of this is xorg-x11, where lib32 isnt a supported configuration,
84# and where lib64 -must- be used on amd64 (for applications that need lib
85# to be 32bit, such as adobe acrobat). Note that this override also bypasses

101# in some cases when linking dynamic, the .a in /usr/lib is used

182# This function is for bulk patching, or in theory for just one 259# @FUNCTION: epatch
183# 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.
184# 267#
185# 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
186# Currently all patches should be the same format. 269# specified by EPATCH_SOURCE.
187# 270#
188# You do not have to specify '-p' option to patch, as it will 271# When processing directories, epatch will apply all patches that match:
189# try with -p0 to -p5 until it succeed, or fail at -p5. 272# @CODE
190# 273# if ${EPATCH_FORCE} != "yes"
191# Above EPATCH_* variables can be used to control various defaults,
192# bug they should be left as is to ensure an ebuild can rely on
193# them for.
194#
195# Patches are applied in current directory.
196#
197# Bulk Patches should preferibly have the form of:
198#
199# ??_${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.
200# 283#
201# For example: 284# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
285# for patches to apply.
202# 286#
203# 01_all_misc-fix.patch.bz2 287# Refer to the other EPATCH_xxx variables for more customization of behavior.
204# 02_sparc_another-fix.patch.bz2
205#
206# This ensures that there are a set order, and you can have ARCH
207# specific patches.
208#
209# If you however give an argument to epatch(), it will treat it as a
210# single patch that need to be applied if its a file. If on the other
211# hand its a directory, it will set EPATCH_SOURCE to this.

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

544# level. The first call is the time when the patches will be

548# have been applied, so that their code can be modified as well, but

987# - you have to specify the off_t size ... i have no idea how to extract that

989# the size of the off_t type (in bytes) on the machine that built the pdv
990# archive. one way to determine this is by running the following commands:
991# strings <pdv archive> | grep lseek
992# strace -elseek <pdv archive>
993# basically look for the first lseek command (we do the strings/grep because
994# sometimes the function call is _llseek or something) and steal the 2nd
995# parameter. here is an example:
996# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
997# lseek
998# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
999# lseek(3, -4, SEEK_END) = 2981250
