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.

46# This function generate linker scripts in /usr/lib for dynamic 54else
47# libs in /lib. This is to fix linking problems when you have
48# the .so in /lib, and the .a in /usr/lib. What happens is that
49# in some cases when linking dynamic, the .a in /usr/lib is used
50# instead of the .so in /lib due to gcc/libtool tweaking ld's
51# library search path. This cause many builds to fail.
52# See bug #4411 for more info.

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

98# @FUNCTION: eshopts_push
99# @USAGE: [options to `set` or `shopt`]
100# @DESCRIPTION:
101# Often times code will want to enable a shell option to change code behavior.
102# Since changing shell options can easily break other pieces of code (which
103# assume the default state), eshopts_push is used to (1) push the current shell
104# options onto a stack and (2) pass the specified arguments to set.
105#
106# If the first argument is '-s' or '-u', we assume you want to call `shopt`
107# rather than `set` as there are some options only available via that.
108#
109# A common example is to disable shell globbing so that special meaning/care
110# may be used with variables/arguments to custom functions. That would be:
111# @CODE
112# eshopts_push -o noglob
113# for x in ${foo} ; do
114# if ...some check... ; then
115# eshopts_pop
116# return 0
117# fi
82 done 118# done
119# eshopts_pop
120# @CODE
121eshopts_push() {
122 # have to assume __ESHOPTS_SAVE__ isn't screwed with
123 # as a `declare -a` here will reset its value
124 local i=${#__ESHOPTS_SAVE__[@]}
125 if [[ $1 == -[su] ]] ; then
126 __ESHOPTS_SAVE__[$i]=$(shopt -p)

136# @FUNCTION: eshopts_pop

107# This function is for bulk patching, or in theory for just one 191# @FUNCTION: epatch
108# or two patches. 192# @USAGE: [patches] [dirs of patches]
193# @DESCRIPTION:
194# epatch is designed to greatly simplify the application of patches. It can
195# process patch files directly, or directories of patches. The patches may be
196# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
197# the -p option as epatch will automatically attempt -p0 to -p5 until things
198# apply successfully.
109# 199#
110# It should work with .bz2, .gz, .zip and plain text patches. 200# If you do not specify any options, then epatch will default to the directory
111# Currently all patches should be the same format. 201# specified by EPATCH_SOURCE.
112# 202#
113# You do not have to specify '-p' option to patch, as it will 203# When processing directories, epatch will apply all patches that match:
114# try with -p0 to -p5 until it succeed, or fail at -p5. 204# @CODE
115# 205# if ${EPATCH_FORCE} != "yes"
116# Above EPATCH_* variables can be used to control various defaults,
117# bug they should be left as is to ensure an ebuild can rely on
118# them for.
119#
120# Patches are applied in current directory.
121#
122# Bulk Patches should preferibly have the form of:
123#
124# ??_${ARCH}_foo.${EPATCH_SUFFIX} 206# ??_${ARCH}_foo.${EPATCH_SUFFIX}
207# else
208# *.${EPATCH_SUFFIX}
209# @CODE
210# The leading ?? are typically numbers used to force consistent patch ordering.
211# The arch field is used to apply patches only for the host architecture with
212# the special value of "all" means apply for everyone. Note that using values
213# other than "all" is highly discouraged -- you should apply patches all the
214# time and let architecture details be detected at configure/compile time.
125# 215#
126# For example: 216# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
217# for patches to apply.
127# 218#
128# 01_all_misc-fix.patch.bz2 219# Refer to the other EPATCH_xxx variables for more customization of behavior.
129# 02_sparc_another-fix.patch.bz2
130#
131# This ensures that there are a set order, and you can have ARCH
132# specific patches.
133#
134# If you however give an argument to epatch(), it will treat it as a
135# single patch that need to be applied if its a file. If on the other
136# hand its a directory, it will set EPATCH_SOURCE to this.

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

2003# @USAGE: [-a|-o] <paths>
2004# @DESCRIPTION:
2005# Check if the specified paths exist. Works for all types of paths
2006# (files/dirs/etc...). The -a and -o flags control the requirements
2007# of the paths. They correspond to "and" and "or" logic. So the -a
2008# flag means all the paths must exist while the -o flag means at least
2009# one of the paths must exist. The default behavior is "and". If no
2010# paths are specified, then the return value is "false".
