14 9# @DESCRIPTION:
15DESCRIPTION="Based on the ${ECLASS} eclass" 10# The eutils eclass contains a suite of functions that complement
16 11# the ones that ebuild.sh already contain. The idea is that the functions
17# 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
18# libs in /lib. This is to fix linking problems when you have 13# home rather than having multiple ebuilds implementing the same thing.
19# the .so in /lib, and the .a in /usr/lib. What happens is that
20# in some cases when linking dynamic, the .a in /usr/lib is used
21# instead of the .so in /lib due to gcc/libtool tweaking ld's
22# library search path. This cause many builds to fail.
23# See bug #4411 for more info.
24# 14#
25# To use, simply call: 15# Due to the nature of this eclass, some functions may have maintainers
26# 16# different from the overall eclass!
27# gen_usr_ldscript libfoo.so
28#
29# Note that you should in general use the unversioned name of
30# the library, as ldconfig should usually update it correctly
31# to point to the latest version of the library present.

149# @FUNCTION: eshopts_push
150# @USAGE: [options to `set` or `shopt`]
151# @DESCRIPTION:
152# Often times code will want to enable a shell option to change code behavior.
153# Since changing shell options can easily break other pieces of code (which
154# assume the default state), eshopts_push is used to (1) push the current shell
155# options onto a stack and (2) pass the specified arguments to set.
156#
157# If the first argument is '-s' or '-u', we assume you want to call `shopt`
158# rather than `set` as there are some options only available via that.
159#
160# A common example is to disable shell globbing so that special meaning/care
161# may be used with variables/arguments to custom functions. That would be:
162# @CODE
163# eshopts_push -s noglob
164# for x in ${foo} ; do
165# if ...some check... ; then
166# eshopts_pop

98# This function is for bulk patching, or in theory for just one 270# @FUNCTION: epatch
99# or two patches. 271# @USAGE: [options] [patches] [dirs of patches]
272# @DESCRIPTION:
273# epatch is designed to greatly simplify the application of patches. It can
274# process patch files directly, or directories of patches. The patches may be
275# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
276# the -p option as epatch will automatically attempt -p0 to -p5 until things
277# apply successfully.
100# 278#
101# It should work with .bz2, .gz, .zip and plain text patches. 279# If you do not specify any patches/dirs, then epatch will default to the
102# Currently all patches should be the same format. 280# directory specified by EPATCH_SOURCE.
103# 281#
104# You do not have to specify '-p' option to patch, as it will 282# Any options specified that start with a dash will be passed down to patch
105# try with -p0 to -p5 until it succeed, or fail at -p5. 283# for this specific invocation. As soon as an arg w/out a dash is found, then
284# arg processing stops.
106# 285#
107# Above EPATCH_* variables can be used to control various defaults, 286# When processing directories, epatch will apply all patches that match:
108# bug they should be left as is to ensure an ebuild can rely on 287# @CODE
109# them for. 288# if ${EPATCH_FORCE} != "yes"
110#
111# Patches are applied in current directory.
112#
113# Bulk Patches should preferibly have the form of:
114#
115# ??_${ARCH}_foo.${EPATCH_SUFFIX} 289# ??_${ARCH}_foo.${EPATCH_SUFFIX}
290# else
291# *.${EPATCH_SUFFIX}
292# @CODE
293# The leading ?? are typically numbers used to force consistent patch ordering.
294# The arch field is used to apply patches only for the host architecture with
295# the special value of "all" means apply for everyone. Note that using values
296# other than "all" is highly discouraged -- you should apply patches all the
297# time and let architecture details be detected at configure/compile time.
116# 298#
117# For example: 299# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
300# for patches to apply.
118# 301#
119# 01_all_misc-fix.patch.bz2 302# Refer to the other EPATCH_xxx variables for more customization of behavior.
120# 02_sparc_another-fix.patch.bz2
121#
122# This ensures that there are a set order, and you can have ARCH
123# specific patches.
124#
125# If you however give an argument to epatch(), it will treat it as a
126# single patch that need to be applied if its a file. If on the other
127# hand its a directory, it will set EPATCH_SOURCE to this.

571# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>[:SLOT]/, where the first
572# of these three directories to exist will be the one to use, ignoring
573# any more general directories which might exist as well. They must end
574# in ".patch" to be applied.
575#
576# User patches are intended for quick testing of patches without ebuild
577# modifications, as well as for permanent customizations a user might
578# desire. Obviously, there can be no official support for arbitrarily
579# patched ebuilds. So whenever a build log in a bug report mentions that
580# user patches were applied, the user should be asked to reproduce the
581# problem without these.
582#
583# Not all ebuilds do call this function, so placing patches in the
584# stated directory might or might not work, depending on the package and
585# the eclasses it inherits and uses. It is safe to call the function
586# repeatedly, so it is always possible to add a call at the ebuild
587# level. The first call is the time when the patches will be
588# applied.
589#
590# Ideally, this function should be called after gentoo-specific patches
591# have been applied, so that their code can be modified as well, but
