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

178# This function is for bulk patching, or in theory for just one 353# @FUNCTION: epatch
179# or two patches. 354# @USAGE: [options] [patches] [dirs of patches]
355# @DESCRIPTION:
356# epatch is designed to greatly simplify the application of patches. It can
357# process patch files directly, or directories of patches. The patches may be
358# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
359# the -p option as epatch will automatically attempt -p0 to -p4 until things
360# apply successfully.
180# 361#
181# It should work with .bz2, .gz, .zip and plain text patches. 362# If you do not specify any patches/dirs, then epatch will default to the
182# Currently all patches should be the same format. 363# directory specified by EPATCH_SOURCE.
183# 364#
184# You do not have to specify '-p' option to patch, as it will 365# Any options specified that start with a dash will be passed down to patch
185# try with -p0 to -p5 until it succeed, or fail at -p5. 366# for this specific invocation. As soon as an arg w/out a dash is found, then
367# arg processing stops.
186# 368#
187# Above EPATCH_* variables can be used to control various defaults, 369# When processing directories, epatch will apply all patches that match:
188# bug they should be left as is to ensure an ebuild can rely on 370# @CODE
189# them for. 371# if ${EPATCH_FORCE} != "yes"
190#
191# Patches are applied in current directory.
192#
193# Bulk Patches should preferibly have the form of:
194#
195# ??_${ARCH}_foo.${EPATCH_SUFFIX} 372# ??_${ARCH}_foo.${EPATCH_SUFFIX}
373# else
374# *.${EPATCH_SUFFIX}
375# @CODE
376# The leading ?? are typically numbers used to force consistent patch ordering.
377# The arch field is used to apply patches only for the host architecture with
378# the special value of "all" means apply for everyone. Note that using values
379# other than "all" is highly discouraged -- you should apply patches all the
380# time and let architecture details be detected at configure/compile time.
196# 381#
197# For example: 382# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
383# for patches to apply.
198# 384#
199# 01_all_misc-fix.patch.bz2 385# Refer to the other EPATCH_xxx variables for more customization of behavior.
200# 02_sparc_another-fix.patch.bz2
201#
202# This ensures that there are a set order, and you can have ARCH
203# specific patches.
204#
205# If you however give an argument to epatch(), it will treat it as a
206# single patch that need to be applied if its a file. If on the other
207# hand its a directory, it will set EPATCH_SOURCE to this.

667# User patches are intended for quick testing of patches without ebuild
668# modifications, as well as for permanent customizations a user might
669# desire. Obviously, there can be no official support for arbitrarily

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

1150# - you have to specify the off_t size ... i have no idea how to extract that

1152# the size of the off_t type (in bytes) on the machine that built the pdv
1153# archive. one way to determine this is by running the following commands:
1154# strings <pdv archive> | grep lseek
1155# strace -elseek <pdv archive>
1156# basically look for the first lseek command (we do the strings/grep because
1157# sometimes the function call is _llseek or something) and steal the 2nd
1158# parameter. here is an example:
1159# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1160# lseek
1161# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1162# lseek(3, -4, SEEK_END) = 2981250

1697# ex: built_with_use xchat gtk2
1698# 1295#
1699# Flags: -a all USE flags should be utilized 1296# A temporary hack until portage properly supports DEPENDing on USE
1700# -o at least one USE flag should be utilized 1297# flags being enabled in packages. This will check to see if the specified
1701# Note: the default flag is '-a' 1298# DEPEND atom was built with the specified list of USE flags. The
1299# --missing option controls the behavior if called on a package that does
1300# not actually support the defined USE flags (aka listed in IUSE).
1301# The default is to abort (call die). The -a and -o flags control
1302# the requirements of the USE flags. They correspond to "and" and "or"
1303# logic. So the -a flag means all listed USE flags must be enabled
1304# while the -o flag means at least one of the listed IUSE flags must be
1305# enabled. The --hidden option is really for internal use only as it
1306# means the USE flag we're checking is hidden expanded, so it won't be found
1307# in IUSE like normal USE flags.
