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)
33# ecpu_check CPU_FLAGS

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

175# This function is for bulk patching, or in theory for just one 270# @FUNCTION: epatch
176# or two patches. 271# @USAGE: [options] [patches] [dirs of patches]
272# @DESCRIPTION:
273# epatch is designed to greatly simplify the application of patches. It can
274# process patch files directly, or directories of patches. The patches may be
275# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
276# the -p option as epatch will automatically attempt -p0 to -p5 until things
277# apply successfully.
177# 278#
178# It should work with .bz2, .gz, .zip and plain text patches. 279# If you do not specify any patches/dirs, then epatch will default to the
179# Currently all patches should be the same format. 280# directory specified by EPATCH_SOURCE.
180# 281#
181# You do not have to specify '-p' option to patch, as it will 282# Any options specified that start with a dash will be passed down to patch
182# try with -p0 to -p5 until it succeed, or fail at -p5. 283# for this specific invocation. As soon as an arg w/out a dash is found, then
284# arg processing stops.
183# 285#
184# Above EPATCH_* variables can be used to control various defaults, 286# When processing directories, epatch will apply all patches that match:
185# bug they should be left as is to ensure an ebuild can rely on 287# @CODE
186# them for. 288# if ${EPATCH_FORCE} != "yes"
187#
188# Patches are applied in current directory.
189#
190# Bulk Patches should preferibly have the form of:
191#
192# ??_${ARCH}_foo.${EPATCH_SUFFIX} 289# ??_${ARCH}_foo.${EPATCH_SUFFIX}
290# else
291# *.${EPATCH_SUFFIX}
292# @CODE
293# The leading ?? are typically numbers used to force consistent patch ordering.
294# The arch field is used to apply patches only for the host architecture with
295# the special value of "all" means apply for everyone. Note that using values
296# other than "all" is highly discouraged -- you should apply patches all the
297# time and let architecture details be detected at configure/compile time.
193# 298#
194# For example: 299# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
300# for patches to apply.
195# 301#
196# 01_all_misc-fix.patch.bz2 302# Refer to the other EPATCH_xxx variables for more customization of behavior.
197# 02_sparc_another-fix.patch.bz2
198#
199# This ensures that there are a set order, and you can have ARCH
200# specific patches.
201#
202# If you however give an argument to epatch(), it will treat it as a
203# single patch that need to be applied if its a file. If on the other
204# hand its a directory, it will set EPATCH_SOURCE to this.

577# of these three directories to exist will be the one to use, ignoring
578# any more general directories which might exist as well. They must end
579# in ".patch" to be applied.
580#
581# User patches are intended for quick testing of patches without ebuild
582# modifications, as well as for permanent customizations a user might
583# desire. Obviously, there can be no official support for arbitrarily
584# patched ebuilds. So whenever a build log in a bug report mentions that
585# user patches were applied, the user should be asked to reproduce the
586# problem without these.
587#
588# Not all ebuilds do call this function, so placing patches in the
589# stated directory might or might not work, depending on the package and
590# the eclasses it inherits and uses. It is safe to call the function
591# repeatedly, so it is always possible to add a call at the ebuild
592# level. The first call is the time when the patches will be
593# applied.
594#
595# Ideally, this function should be called after gentoo-specific patches
596# have been applied, so that their code can be modified as well, but
