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!

21# the .so in /lib, and the .a in /usr/lib. What happens is that
22# in some cases when linking dynamic, the .a in /usr/lib is used
23# instead of the .so in /lib due to gcc/libtool tweaking ld's
24# library search path. This cause many builds to fail.

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 -o noglob
166# for x in ${foo} ; do
167# if ...some check... ; then
168# eshopts_pop

105# This function is for bulk patching, or in theory for just one 264# @FUNCTION: epatch
106# or two patches. 265# @USAGE: [patches] [dirs of patches]
266# @DESCRIPTION:
267# epatch is designed to greatly simplify the application of patches. It can
268# process patch files directly, or directories of patches. The patches may be
269# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
270# the -p option as epatch will automatically attempt -p0 to -p5 until things
271# apply successfully.
107# 272#
108# It should work with .bz2, .gz, .zip and plain text patches. 273# If you do not specify any options, then epatch will default to the directory
109# Currently all patches should be the same format. 274# specified by EPATCH_SOURCE.
110# 275#
111# You do not have to specify '-p' option to patch, as it will 276# When processing directories, epatch will apply all patches that match:
112# try with -p0 to -p5 until it succeed, or fail at -p5. 277# @CODE
113# 278# if ${EPATCH_FORCE} != "yes"
114# Above EPATCH_* variables can be used to control various defaults,
115# bug they should be left as is to ensure an ebuild can rely on
116# them for.
117#
118# Patches are applied in current directory.
119#
120# Bulk Patches should preferibly have the form of:
121#
122# ??_${ARCH}_foo.${EPATCH_SUFFIX} 279# ??_${ARCH}_foo.${EPATCH_SUFFIX}
280# else
281# *.${EPATCH_SUFFIX}
282# @CODE
283# The leading ?? are typically numbers used to force consistent patch ordering.
284# The arch field is used to apply patches only for the host architecture with
285# the special value of "all" means apply for everyone. Note that using values
286# other than "all" is highly discouraged -- you should apply patches all the
287# time and let architecture details be detected at configure/compile time.
123# 288#
124# For example: 289# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
290# for patches to apply.
125# 291#
126# 01_all_misc-fix.patch.bz2 292# Refer to the other EPATCH_xxx variables for more customization of behavior.
127# 02_sparc_another-fix.patch.bz2
128#
129# This ensures that there are a set order, and you can have ARCH
130# specific patches.
131#
132# If you however give an argument to epatch(), it will treat it as a
133# single patch that need to be applied if its a file. If on the other
134# hand its a directory, it will set EPATCH_SOURCE to this.

521# Applies user-provided patches to the source tree. The patches are
522# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
523# of these three directories to exist will be the one to use, ignoring
524# any more general directories which might exist as well.
525#
526# User patches are intended for quick testing of patches without ebuild
527# modifications, as well as for permanent customizations a user might
528# desire. Obviously, there can be no official support for arbitrarily
529# patched ebuilds. So whenever a build log in a bug report mentions that
530# user patches were applied, the user should be asked to reproduce the
531# problem without these.
532#
533# Not all ebuilds do call this function, so placing patches in the
534# stated directory might or might not work, depending on the package and
535# the eclasses it inherits and uses. It is safe to call the function
536# repeatedly, so it is always possible to add a call at the ebuild
537# level. The first call is the time when the patches will be
538# applied.
539#
540# Ideally, this function should be called after gentoo-specific patches
541# have been applied, so that their code can be modified as well, but
542# before calls to e.g. eautoreconf, as the user patches might affect
543# autotool input files as well.

714# new convenience patch wrapper function to eventually replace epatch(),
715# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and
716# /usr/bin/patch
717# Features:
718# - bulk patch handling similar to epatch()'s
719# - automatic patch level detection like epatch()'s
720# - automatic patch uncompression like epatch()'s
721# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
722# manually instead
723# - once I decide it's production-ready, it'll be called from base_src_unpack
724# to handle $PATCHES to avoid defining src_unpack just to use xpatch
725
726# accepts zero or more parameters specifying patchfiles and/or patchdirs
727
728# known issues:
729# - only supports unified style patches (does anyone _really_ use anything
730# else?)
731# - because it doesn't use --dry-run there is a risk of it failing
732# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
733# any of the backup heuristics that patch employs to discover a filename.
734# however, this isn't dangerous because if it works for the developer who's
735# writing the ebuild, it'll always work for the users, and if it doesn't,
736# then we'll fix it :-)
737# - no support as yet for patches applying outside $S (and not directly in $WORKDIR).

970# @DESCRIPTION:
971# Unpack those pesky pdv generated files ...
972# They're self-unpacking programs with the binary package stuffed in
973# the middle of the archive. Valve seems to use it a lot ... too bad
974# it seems to like to segfault a lot :(. So lets take it apart ourselves.
975#
976# You have to specify the off_t size ... I have no idea how to extract that
977# information out of the binary executable myself. Basically you pass in
978# the size of the off_t type (in bytes) on the machine that built the pdv
979# archive.
980#
981# One way to determine this is by running the following commands:
982#
983# @CODE
984# strings <pdv archive> | grep lseek
985# strace -elseek <pdv archive>
986# @CODE
987#
988# Basically look for the first lseek command (we do the strings/grep because
989# sometimes the function call is _llseek or something) and steal the 2nd
990# parameter. Here is an example:
991#
992# @CODE
993# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
994# lseek
995# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
996# lseek(3, -4, SEEK_END) = 2981250
997# @CODE
998#
999# Thus we would pass in the value of '4' as the second parameter.

1496#
1497# Deprecated: Use EAPI 2 use deps in DEPEND|RDEPEND and with has_version calls.
1498#
1499# A temporary hack until portage properly supports DEPENDing on USE
1500# flags being enabled in packages. This will check to see if the specified
1501# DEPEND atom was built with the specified list of USE flags. The
1502# --missing option controls the behavior if called on a package that does
1503# not actually support the defined USE flags (aka listed in IUSE).
1504# The default is to abort (call die). The -a and -o flags control
1505# the requirements of the USE flags. They correspond to "and" and "or"
1506# logic. So the -a flag means all listed USE flags must be enabled
1507# while the -o flag means at least one of the listed IUSE flags must be
1508# enabled. The --hidden option is really for internal use only as it
1509# means the USE flag we're checking is hidden expanded, so it won't be found
1510# in IUSE like normal USE flags.
