5# This eclass is for general purpose functions that most ebuilds
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!

152# @USAGE: [options to `set` or `shopt`]

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

111# This function is for bulk patching, or in theory for just one 264# @FUNCTION: epatch
112# or two patches. 265# @USAGE: [patches] [dirs of patches]
266# @DESCRIPTION:
267# epatch is designed to greatly simplify the application of patches. It can
268# process patch files directly, or directories of patches. The patches may be
269# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
270# the -p option as epatch will automatically attempt -p0 to -p5 until things
271# apply successfully.
113# 272#
114# It should work with .bz2, .gz, .zip and plain text patches. 273# If you do not specify any options, then epatch will default to the directory
115# Currently all patches should be the same format. 274# specified by EPATCH_SOURCE.
116# 275#
117# You do not have to specify '-p' option to patch, as it will 276# When processing directories, epatch will apply all patches that match:
118# try with -p0 to -p5 until it succeed, or fail at -p5. 277# @CODE
119# 278# if ${EPATCH_FORCE} != "yes"
120# Above EPATCH_* variables can be used to control various defaults,
121# bug they should be left as is to ensure an ebuild can rely on
122# them for.
123#
124# Patches are applied in current directory.
125#
126# Bulk Patches should preferibly have the form of:
127#
128# ??_${ARCH}_foo.${EPATCH_SUFFIX} 279# ??_${ARCH}_foo.${EPATCH_SUFFIX}
280# else
281# *.${EPATCH_SUFFIX}
282# @CODE
283# The leading ?? are typically numbers used to force consistent patch ordering.
284# The arch field is used to apply patches only for the host architecture with
285# the special value of "all" means apply for everyone. Note that using values
286# other than "all" is highly discouraged -- you should apply patches all the
287# time and let architecture details be detected at configure/compile time.
129# 288#
130# For example: 289# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
290# for patches to apply.
131# 291#
132# 01_all_misc-fix.patch.bz2 292# Refer to the other EPATCH_xxx variables for more customization of behavior.
133# 02_sparc_another-fix.patch.bz2
134#
135# This ensures that there are a set order, and you can have ARCH
136# specific patches.
137#
138# If you however give an argument to epatch(), it will treat it as a
139# single patch that need to be applied if its a file. If on the other
140# hand its a directory, it will set EPATCH_SOURCE to this.

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