6# @MAINTAINER:
7# base-system@gentoo.org
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.
4# 14#
5# Author: Martin Schlemmer <azarah@gentoo.org> 15# Due to the nature of this eclass, some functions may have maintainers
6# 16# different from the overall eclass!
7# This eclass is for general purpose functions that most ebuilds
8# have to implement themselves.

47# This function generate linker scripts in /usr/lib for dynamic 54else

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

60# the library, as ldconfig should usually update it correctly

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 ${foo} ; do
115# if ...some check... ; then
116# eshopts_pop
117# return 0
118# fi
83 done 119# done
120# eshopts_pop
121# @CODE
122eshopts_push() {
123 # have to assume __ESHOPTS_SAVE__ isn't screwed with
124 # as a `declare -a` here will reset its value
125 local i=${#__ESHOPTS_SAVE__[@]}
126 if [[ $1 == -[su] ]] ; then

137# @FUNCTION: eshopts_pop

109# This function is for bulk patching, or in theory for just one 192# @FUNCTION: epatch
110# 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.
111# 200#
112# 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
113# Currently all patches should be the same format. 202# specified by EPATCH_SOURCE.
114# 203#
115# You do not have to specify '-p' option to patch, as it will 204# When processing directories, epatch will apply all patches that match:
116# try with -p0 to -p5 until it succeed, or fail at -p5. 205# @CODE
117# 206# if ${EPATCH_FORCE} != "yes"
118# Above EPATCH_* variables can be used to control various defaults,
119# bug they should be left as is to ensure an ebuild can rely on
120# them for.
121#
122# Patches are applied in current directory.
123#
124# Bulk Patches should preferibly have the form of:
125#
126# ??_${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.
127# 216#
128# For example: 217# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
218# for patches to apply.
129# 219#
130# 01_all_misc-fix.patch.bz2 220# Refer to the other EPATCH_xxx variables for more customization of behavior.
131# 02_sparc_another-fix.patch.bz2
132#
133# This ensures that there are a set order, and you can have ARCH
134# specific patches.
135#
136# If you however give an argument to epatch(), it will treat it as a
137# single patch that need to be applied if its a file. If on the other
138# hand its a directory, it will set EPATCH_SOURCE to this.

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.

2004# @USAGE: [-a|-o] <paths>
2005# @DESCRIPTION:
2006# Check if the specified paths exist. Works for all types of paths
2007# (files/dirs/etc...). The -a and -o flags control the requirements
2008# of the paths. They correspond to "and" and "or" logic. So the -a
2009# flag means all the paths must exist while the -o flag means at least
2010# one of the paths must exist. The default behavior is "and". If no
2011# paths are specified, then the return value is "false".
