6# have to implement themselves.

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!

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

53# To use, simply call:
54#

57# Note that you should in general use the unversioned name of
58# the library, as ldconfig should usually update it correctly
59# to point to the latest version of the library present.

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

138# @FUNCTION: eshopts_pop

142# eshopts_push call. See that function for more details.

107# This function is for bulk patching, or in theory for just one 193# @FUNCTION: epatch
108# or two patches. 194# @USAGE: [patches] [dirs of patches]
195# @DESCRIPTION:
196# epatch is designed to greatly simplify the application of patches. It can
197# process patch files directly, or directories of patches. The patches may be
198# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
199# the -p option as epatch will automatically attempt -p0 to -p5 until things
200# apply successfully.
109# 201#
110# It should work with .bz2, .gz, .zip and plain text patches. 202# If you do not specify any options, then epatch will default to the directory
111# Currently all patches should be the same format. 203# specified by EPATCH_SOURCE.
112# 204#
113# You do not have to specify '-p' option to patch, as it will 205# When processing directories, epatch will apply all patches that match:
114# try with -p0 to -p5 until it succeed, or fail at -p5. 206# @CODE
115# 207# 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.${EPATCH_SUFFIX} 208# ??_${ARCH}_foo.${EPATCH_SUFFIX}
209# else
210# *.${EPATCH_SUFFIX}
211# @CODE
212# The leading ?? are typically numbers used to force consistent patch ordering.
213# The arch field is used to apply patches only for the host architecture with
214# the special value of "all" means apply for everyone. Note that using values
215# other than "all" is highly discouraged -- you should apply patches all the
216# time and let architecture details be detected at configure/compile time.
125# 217#
126# For example: 218# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
219# for patches to apply.
127# 220#
128# 01_all_misc-fix.patch.bz2 221# 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.

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