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!

47# This function generate linker scripts in /usr/lib for dynamic 57else
48# libs in /lib. This is to fix linking problems when you have
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.
53# See bug #4411 for more info.

59# Note that you should in general use the unversioned name of
60# the library, as ldconfig should usually update it correctly

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

109# This function is for bulk patching, or in theory for just one 260# @FUNCTION: epatch
110# or two patches. 261# @USAGE: [patches] [dirs of patches]
262# @DESCRIPTION:
263# epatch is designed to greatly simplify the application of patches. It can
264# process patch files directly, or directories of patches. The patches may be
265# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
266# the -p option as epatch will automatically attempt -p0 to -p5 until things
267# apply successfully.
111# 268#
112# It should work with .bz2, .gz, .zip and plain text patches. 269# If you do not specify any options, then epatch will default to the directory
113# Currently all patches should be the same format. 270# specified by EPATCH_SOURCE.
114# 271#
115# You do not have to specify '-p' option to patch, as it will 272# When processing directories, epatch will apply all patches that match:
116# try with -p0 to -p5 until it succeed, or fail at -p5. 273# @CODE
117# 274# 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.${EPATCH_SUFFIX} 275# ??_${ARCH}_foo.${EPATCH_SUFFIX}
276# else
277# *.${EPATCH_SUFFIX}
278# @CODE
279# The leading ?? are typically numbers used to force consistent patch ordering.
280# The arch field is used to apply patches only for the host architecture with
281# the special value of "all" means apply for everyone. Note that using values
282# other than "all" is highly discouraged -- you should apply patches all the
283# time and let architecture details be detected at configure/compile time.
127# 284#
128# For example: 285# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
286# for patches to apply.
129# 287#
130# 01_all_misc-fix.patch.bz2 288# 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.

517# Applies user-provided patches to the source tree. The patches are
518# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
519# of these three directories to exist will be the one to use, ignoring
520# any more general directories which might exist as well.
521#
522# User patches are intended for quick testing of patches without ebuild
523# modifications, as well as for permanent customizations a user might
524# desire. Obviously, there can be no official support for arbitrarily
525# patched ebuilds. So whenever a build log in a bug report mentions that
526# user patches were applied, the user should be asked to reproduce the
527# problem without these.
528#
529# Not all ebuilds do call this function, so placing patches in the
530# stated directory might or might not work, depending on the package and
531# the eclasses it inherits and uses. It is safe to call the function
532# repeatedly, so it is always possible to add a call at the ebuild
533# level. The first call is the time when the patches will be
534# applied.
535#
536# Ideally, this function should be called after gentoo-specific patches
537# have been applied, so that their code can be modified as well, but
538# before calls to e.g. eautoreconf, as the user patches might affect
539# autotool input files as well.
