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!

20# libs in /lib. This is to fix linking problems when you have
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:
28#
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.

99# @FUNCTION: eshopts_push
100# @USAGE: [options to `set` or `shopt`]
101# @DESCRIPTION:
102# Often times code will want to enable a shell option to change code behavior.
103# Since changing shell options can easily break other pieces of code (which
104# assume the default state), eshopts_push is used to (1) push the current shell
105# options onto a stack and (2) pass the specified arguments to set.
106#
107# If the first argument is '-s' or '-u', we assume you want to call `shopt`
108# rather than `set` as there are some options only available via that.
109#
110# A common example is to disable shell globbing so that special meaning/care
111# may be used with variables/arguments to custom functions. That would be:
112# @CODE
113# eshopts_push -o noglob
114# for x in ${foo} ; do
115# if ...some check... ; then
116# eshopts_pop
85 return 0 117# return 0

123 # have to assume __ESHOPTS_SAVE__ isn't screwed with
124 # as a `declare -a` here will reset its value
125 local i=${#__ESHOPTS_SAVE__[@]}
126 if [[ $1 == -[su] ]] ; then

106# This function is for bulk patching, or in theory for just one 192# @FUNCTION: epatch
107# or two patches. 193# @USAGE: [patches] [dirs of patches]
194# @DESCRIPTION:
195# epatch is designed to greatly simplify the application of patches. It can
196# process patch files directly, or directories of patches. The patches may be
197# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
198# the -p option as epatch will automatically attempt -p0 to -p5 until things
199# apply successfully.
108# 200#
109# It should work with .bz2, .gz, .zip and plain text patches. 201# If you do not specify any options, then epatch will default to the directory
110# Currently all patches should be the same format. 202# specified by EPATCH_SOURCE.
111# 203#
112# You do not have to specify '-p' option to patch, as it will 204# When processing directories, epatch will apply all patches that match:
113# try with -p0 to -p5 until it succeed, or fail at -p5. 205# @CODE
114# 206# if ${EPATCH_FORCE} != "yes"
115# Above EPATCH_* variables can be used to control various defaults,
116# bug they should be left as is to ensure an ebuild can rely on
117# them for.
118#
119# Patches are applied in current directory.
120#
121# Bulk Patches should preferibly have the form of:
122#
123# ??_${ARCH}_foo.${EPATCH_SUFFIX} 207# ??_${ARCH}_foo.${EPATCH_SUFFIX}
208# else
209# *.${EPATCH_SUFFIX}
210# @CODE
211# The leading ?? are typically numbers used to force consistent patch ordering.
212# The arch field is used to apply patches only for the host architecture with
213# the special value of "all" means apply for everyone. Note that using values
214# other than "all" is highly discouraged -- you should apply patches all the
215# time and let architecture details be detected at configure/compile time.
124# 216#
125# For example: 217# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
218# for patches to apply.
126# 219#
127# 01_all_misc-fix.patch.bz2 220# 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.

448# @DESCRIPTION:
449# Applies user-provided patches to the source tree. The patches are
450# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
451# of these three directories to exist will be the one to use, ignoring
452# any more general directories which might exist as well.
453#
454# User patches are intended for quick testing of patches without ebuild
455# modifications, as well as for permanent customizations a user might
456# desire. Obviously, there can be no official support for arbitrarily
457# patched ebuilds. So whenever a build log in a bug report mentions that
458# user patches were applied, the user should be asked to reproduce the
459# problem without these.
460#
461# Not all ebuilds do call this function, so placing patches in the
462# stated directory might or might not work, depending on the package and
463# the eclasses it inherits and uses. It is safe to call the function
464# repeatedly, so it is always possible to add a call at the ebuild
465# level. The first call is the time when the patches will be
466# applied.
467#
468# Ideally, this function should be called after gentoo-specific patches
469# have been applied, so that their code can be modified as well, but
470# before calls to e.g. eautoreconf, as the user patches might affect
471# autotool input files as well.

762# new convenience patch wrapper function to eventually replace epatch(),
763# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and
764# /usr/bin/patch
765# Features:
766# - bulk patch handling similar to epatch()'s
767# - automatic patch level detection like epatch()'s
768# - automatic patch uncompression like epatch()'s
769# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
770# manually instead
771# - once I decide it's production-ready, it'll be called from base_src_unpack
772# to handle $PATCHES to avoid defining src_unpack just to use xpatch
773
774# accepts zero or more parameters specifying patchfiles and/or patchdirs
775
776# known issues:
777# - only supports unified style patches (does anyone _really_ use anything
778# else?)
779# - because it doesn't use --dry-run there is a risk of it failing
780# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
781# any of the backup heuristics that patch employs to discover a filename.
782# however, this isn't dangerous because if it works for the developer who's
783# writing the ebuild, it'll always work for the users, and if it doesn't,
784# then we'll fix it :-)
785# - no support as yet for patches applying outside $S (and not directly in $WORKDIR).
