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.

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!

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

105# This function is for bulk patching, or in theory for just one 353# @FUNCTION: epatch
106# 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.
107# 361#
108# 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
109# Currently all patches should be the same format. 363# directory specified by EPATCH_SOURCE.
110# 364#
111# 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
112# 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.
113# 368#
114# Above EPATCH_* variables can be used to control various defaults, 369# When processing directories, epatch will apply all patches that match:
115# bug they should be left as is to ensure an ebuild can rely on 370# @CODE
116# them for. 371# if ${EPATCH_FORCE} != "yes"
117#
118# Patches are applied in current directory.
119#
120# Bulk Patches should preferibly have the form of:
121#
122# ??_${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.
123# 381#
124# For example: 382# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
383# for patches to apply.
125# 384#
126# 01_all_misc-fix.patch.bz2 385# 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.

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

645# /usr/bin/patch
646# Features:
647# - bulk patch handling similar to epatch()'s
648# - automatic patch level detection like epatch()'s
649# - automatic patch uncompression like epatch()'s
650# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
651# manually instead
652# - once I decide it's production-ready, it'll be called from base_src_unpack
653# to handle $PATCHES to avoid defining src_unpack just to use xpatch
654
655# accepts zero or more parameters specifying patchfiles and/or patchdirs
656
657# known issues:
658# - only supports unified style patches (does anyone _really_ use anything
659# else?)
660# - because it doesn't use --dry-run there is a risk of it failing
661# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
662# any of the backup heuristics that patch employs to discover a filename.
663# however, this isn't dangerous because if it works for the developer who's
664# writing the ebuild, it'll always work for the users, and if it doesn't,
665# then we'll fix it :-)
666# - no support as yet for patches applying outside $S (and not directly in $WORKDIR).
