15 8# @BLURB: many extra (but common) functions that are used in ebuilds
16DEPEND="!bootstrap? ( sys-devel/patch )" 9# @DESCRIPTION:
17 10# The eutils eclass contains a suite of functions that complement
18DESCRIPTION="Based on the ${ECLASS} eclass" 11# the ones that ebuild.sh already contain. The idea is that the functions
19 12# are not required in all ebuilds but enough utilize them to have a common
20# ecpu_check 13# home rather than having multiple ebuilds implementing the same thing.
21# Usage:
22# 14#
23# ecpu_check array_of_cpu_flags 15# Due to the nature of this eclass, some functions may have maintainers
24# 16# different from the overall eclass!
25# array_of_cpu_flags - An array of cpu flags to check against USE flags
26#
27# Checks user USE related cpu flags against /proc/cpuinfo. If user enables a
28# cpu flag that is not supported in their processor flags, it will warn the
29# user if CROSSCOMPILE is not set to 1 ( because cross compile users are
30# obviously using different cpu flags than their own cpu ). Examples:
31#
32# CPU_FLAGS=(mmx mmx2 sse sse2)

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

172# This function is for bulk patching, or in theory for just one 265# @FUNCTION: epatch
173# or two patches. 266# @USAGE: [options] [patches] [dirs of patches]
267# @DESCRIPTION:
268# epatch is designed to greatly simplify the application of patches. It can
269# process patch files directly, or directories of patches. The patches may be
270# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
271# the -p option as epatch will automatically attempt -p0 to -p5 until things
272# apply successfully.
174# 273#
175# It should work with .bz2, .gz, .zip and plain text patches. 274# If you do not specify any patches/dirs, then epatch will default to the
176# Currently all patches should be the same format. 275# directory specified by EPATCH_SOURCE.
177# 276#
178# You do not have to specify '-p' option to patch, as it will 277# Any options specified that start with a dash will be passed down to patch
179# try with -p0 to -p5 until it succeed, or fail at -p5. 278# for this specific invocation. As soon as an arg w/out a dash is found, then
279# arg processing stops.
180# 280#
181# Above EPATCH_* variables can be used to control various defaults, 281# When processing directories, epatch will apply all patches that match:
182# bug they should be left as is to ensure an ebuild can rely on 282# @CODE
183# them for. 283# if ${EPATCH_FORCE} != "yes"
184#
185# Patches are applied in current directory.
186#
187# Bulk Patches should preferibly have the form of:
188#
189# ??_${ARCH}_foo.${EPATCH_SUFFIX} 284# ??_${ARCH}_foo.${EPATCH_SUFFIX}
285# else
286# *.${EPATCH_SUFFIX}
287# @CODE
288# The leading ?? are typically numbers used to force consistent patch ordering.
289# The arch field is used to apply patches only for the host architecture with
290# the special value of "all" means apply for everyone. Note that using values
291# other than "all" is highly discouraged -- you should apply patches all the
292# time and let architecture details be detected at configure/compile time.
190# 293#
191# For example: 294# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
295# for patches to apply.
192# 296#
193# 01_all_misc-fix.patch.bz2 297# Refer to the other EPATCH_xxx variables for more customization of behavior.
194# 02_sparc_another-fix.patch.bz2
195#
196# This ensures that there are a set order, and you can have ARCH
197# specific patches.
198#
199# If you however give an argument to epatch(), it will treat it as a
200# single patch that need to be applied if its a file. If on the other
201# hand its a directory, it will set EPATCH_SOURCE to this.

555# of these three directories to exist will be the one to use, ignoring
556# any more general directories which might exist as well. They must end
557# in ".patch" to be applied.
558#
559# User patches are intended for quick testing of patches without ebuild
560# modifications, as well as for permanent customizations a user might
561# desire. Obviously, there can be no official support for arbitrarily
562# patched ebuilds. So whenever a build log in a bug report mentions that
563# user patches were applied, the user should be asked to reproduce the
564# problem without these.
565#
566# Not all ebuilds do call this function, so placing patches in the
567# stated directory might or might not work, depending on the package and
568# the eclasses it inherits and uses. It is safe to call the function
569# repeatedly, so it is always possible to add a call at the ebuild
570# level. The first call is the time when the patches will be
571# applied.
572#
573# Ideally, this function should be called after gentoo-specific patches
574# have been applied, so that their code can be modified as well, but
