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 -s 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 258# @FUNCTION: epatch
106# or two patches. 259# @USAGE: [patches] [dirs of patches]
260# @DESCRIPTION:
261# epatch is designed to greatly simplify the application of patches. It can
262# process patch files directly, or directories of patches. The patches may be
263# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
264# the -p option as epatch will automatically attempt -p0 to -p5 until things
265# apply successfully.
107# 266#
108# It should work with .bz2, .gz, .zip and plain text patches. 267# If you do not specify any options, then epatch will default to the directory
109# Currently all patches should be the same format. 268# specified by EPATCH_SOURCE.
110# 269#
111# You do not have to specify '-p' option to patch, as it will 270# When processing directories, epatch will apply all patches that match:
112# try with -p0 to -p5 until it succeed, or fail at -p5. 271# @CODE
113# 272# 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.${EPATCH_SUFFIX} 273# ??_${ARCH}_foo.${EPATCH_SUFFIX}
274# else
275# *.${EPATCH_SUFFIX}
276# @CODE
277# The leading ?? are typically numbers used to force consistent patch ordering.
278# The arch field is used to apply patches only for the host architecture with
279# the special value of "all" means apply for everyone. Note that using values
280# other than "all" is highly discouraged -- you should apply patches all the
281# time and let architecture details be detected at configure/compile time.
123# 282#
124# For example: 283# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
284# for patches to apply.
125# 285#
126# 01_all_misc-fix.patch.bz2 286# 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.

515# Applies user-provided patches to the source tree. The patches are
516# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
517# of these three directories to exist will be the one to use, ignoring
518# any more general directories which might exist as well.
519#
520# User patches are intended for quick testing of patches without ebuild
521# modifications, as well as for permanent customizations a user might
522# desire. Obviously, there can be no official support for arbitrarily
523# patched ebuilds. So whenever a build log in a bug report mentions that
524# user patches were applied, the user should be asked to reproduce the
525# problem without these.
526#
527# Not all ebuilds do call this function, so placing patches in the
528# stated directory might or might not work, depending on the package and
529# the eclasses it inherits and uses. It is safe to call the function
530# repeatedly, so it is always possible to add a call at the ebuild
531# level. The first call is the time when the patches will be
532# applied.
533#
534# Ideally, this function should be called after gentoo-specific patches
535# have been applied, so that their code can be modified as well, but
536# before calls to e.g. eautoreconf, as the user patches might affect
537# autotool input files as well.

712# new convenience patch wrapper function to eventually replace epatch(),
713# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and
714# /usr/bin/patch
715# Features:
716# - bulk patch handling similar to epatch()'s
717# - automatic patch level detection like epatch()'s
718# - automatic patch uncompression like epatch()'s
719# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
720# manually instead
721# - once I decide it's production-ready, it'll be called from base_src_unpack
722# to handle $PATCHES to avoid defining src_unpack just to use xpatch
723
724# accepts zero or more parameters specifying patchfiles and/or patchdirs
725
726# known issues:
727# - only supports unified style patches (does anyone _really_ use anything
728# else?)
729# - because it doesn't use --dry-run there is a risk of it failing
730# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
731# any of the backup heuristics that patch employs to discover a filename.
732# however, this isn't dangerous because if it works for the developer who's
733# writing the ebuild, it'll always work for the users, and if it doesn't,
734# then we'll fix it :-)

1490#
1491# Deprecated: Use EAPI 2 use deps in DEPEND|RDEPEND and with has_version calls.
1492#
1493# A temporary hack until portage properly supports DEPENDing on USE
1494# flags being enabled in packages. This will check to see if the specified
1495# DEPEND atom was built with the specified list of USE flags. The
1496# --missing option controls the behavior if called on a package that does
1497# not actually support the defined USE flags (aka listed in IUSE).
1498# The default is to abort (call die). The -a and -o flags control
1499# the requirements of the USE flags. They correspond to "and" and "or"
1500# logic. So the -a flag means all listed USE flags must be enabled
1501# while the -o flag means at least one of the listed IUSE flags must be
1502# enabled. The --hidden option is really for internal use only as it
1503# means the USE flag we're checking is hidden expanded, so it won't be found
1504# in IUSE like normal USE flags.
