16 9# @DESCRIPTION:
17DESCRIPTION="Based on the ${ECLASS} eclass" 10# The eutils eclass contains a suite of functions that complement
18 11# the ones that ebuild.sh already contain. The idea is that the functions
19# This function generate linker scripts in /usr/lib for dynamic 12# are not required in all ebuilds but enough utilize them to have a common
20# libs in /lib. This is to fix linking problems when you have 13# home rather than having multiple ebuilds implementing the same thing.
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.
25# See bug #4411 for more info.
26# 14#
27# To use, simply call: 15# Due to the nature of this eclass, some functions may have maintainers
28# 16# different from the overall eclass!
29# gen_usr_ldscript libfoo.so
30#
31# Note that you should in general use the unversioned name of
32# the library, as ldconfig should usually update it correctly
33# to point to the latest version of the library present.

220# @FUNCTION: eshopts_push
221# @USAGE: [options to `set` or `shopt`]
222# @DESCRIPTION:
223# Often times code will want to enable a shell option to change code behavior.
224# Since changing shell options can easily break other pieces of code (which
225# assume the default state), eshopts_push is used to (1) push the current shell
226# options onto a stack and (2) pass the specified arguments to set.
227#
228# If the first argument is '-s' or '-u', we assume you want to call `shopt`
229# rather than `set` as there are some options only available via that.
230#
231# A common example is to disable shell globbing so that special meaning/care
232# may be used with variables/arguments to custom functions. That would be:
233# @CODE
234# eshopts_push -s noglob
235# for x in ${foo} ; do
236# if ...some check... ; then
237# eshopts_pop
238# return 0

106# This function is for bulk patching, or in theory for just one 353# @FUNCTION: epatch
107# 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.
108# 361#
109# 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
110# Currently all patches should be the same format. 363# directory specified by EPATCH_SOURCE.
111# 364#
112# 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
113# 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.
114# 368#
115# Above EPATCH_* variables can be used to control various defaults, 369# When processing directories, epatch will apply all patches that match:
116# bug they should be left as is to ensure an ebuild can rely on 370# @CODE
117# them for. 371# if ${EPATCH_FORCE} != "yes"
118#
119# Patches are applied in current directory.
120#
121# Bulk Patches should preferibly have the form of:
122#
123# ??_${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.
124# 381#
125# For example: 382# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
383# for patches to apply.
126# 384#
127# 01_all_misc-fix.patch.bz2 385# Refer to the other EPATCH_xxx variables for more customization of behavior.
128# 02_sparc_another-fix.patch.bz2
129#
130# This ensures that there are a set order, and you can have ARCH
131# specific patches.
132#
133# If you however give an argument to epatch(), it will treat it as a
134# single patch that need to be applied if its a file. If on the other
135# hand its a directory, it will set EPATCH_SOURCE to this.

661# Applies user-provided patches to the source tree. The patches are
662# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>[:SLOT]/, where the first
663# of these three directories to exist will be the one to use, ignoring
664# any more general directories which might exist as well. They must end
665# in ".patch" to be applied.
666#
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
670# patched ebuilds. So whenever a build log in a bug report mentions that
671# user patches were applied, the user should be asked to reproduce the
672# problem without these.
673#
674# Not all ebuilds do call this function, so placing patches in the
675# stated directory might or might not work, depending on the package and
676# the eclasses it inherits and uses. It is safe to call the function
677# repeatedly, so it is always possible to add a call at the ebuild
678# level. The first call is the time when the patches will be
679# applied.
680#
681# Ideally, this function should be called after gentoo-specific patches
682# have been applied, so that their code can be modified as well, but
683# before calls to e.g. eautoreconf, as the user patches might affect
684# autotool input files as well.

759# new convenience patch wrapper function to eventually replace epatch(),
760# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and
761# /usr/bin/patch
762# Features:
763# - bulk patch handling similar to epatch()'s
764# - automatic patch level detection like epatch()'s
765# - automatic patch uncompression like epatch()'s
766# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
767# manually instead
768# - once I decide it's production-ready, it'll be called from base_src_unpack
769# to handle $PATCHES to avoid defining src_unpack just to use xpatch
770
771# accepts zero or more parameters specifying patchfiles and/or patchdirs
772
773# known issues:
774# - only supports unified style patches (does anyone _really_ use anything
775# else?)
776# - because it doesn't use --dry-run there is a risk of it failing
777# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
778# any of the backup heuristics that patch employs to discover a filename.
779# however, this isn't dangerous because if it works for the developer who's
780# writing the ebuild, it'll always work for the users, and if it doesn't,
781# then we'll fix it :-)

1674# installed. The files must exist, otherwise the function will fail.
1675# In EAPI 4 and subsequent EAPIs DOCS may specify directories as well,
1676# in other EAPIs using directories is unsupported.
1677#
1678# If DOCS is not declared, the files matching patterns given
1679# in the default EAPI implementation of src_install will be installed.
1680# If this is undesired, DOCS can be set to empty value to prevent any
1681# documentation from being installed.
1682#
1683# If HTML_DOCS is declared and non-empty, all files and/or directories
1684# listed in it are installed as HTML docs (using dohtml).
1685#
1686# Both DOCS and HTML_DOCS can either be an array or a whitespace-
1687# separated list. Whenever directories are allowed, '<directory>/.' may
1688# be specified in order to install all files within the directory
1689# without creating a sub-directory in docdir.
