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

137# @FUNCTION: eshopts_pop

141# eshopts_push call. See that function for more details.
142eshopts_pop() {

74# This function is for bulk patching, or in theory for just one 192# @FUNCTION: epatch
75# or two patches. 193# @USAGE: [patches] [dirs of patches]
194# @DESCRIPTION:
195# epatch is designed to greatly simplify the application of patches. It can
196# process patch files directly, or directories of patches. The patches may be
197# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
198# the -p option as epatch will automatically attempt -p0 to -p5 until things
199# apply successfully.
76# 200#
77# It should work with .bz2, .gz, .zip and plain text patches. 201# If you do not specify any options, then epatch will default to the directory
78# Currently all patches should be the same format. 202# specified by EPATCH_SOURCE.
79# 203#
80# You do not have to specify '-p' option to patch, as it will 204# When processing directories, epatch will apply all patches that match:
81# try with -p0 to -p5 until it succeed, or fail at -p5. 205# @CODE
82# 206# if ${EPATCH_FORCE} != "yes"
83# Above EPATCH_* variables can be used to control various defaults,
84# bug they should be left as is to ensure an ebuild can rely on
85# them for.
86#
87# Patches are applied in current directory.
88#
89# Bulk Patches should preferibly have the form of:
90#
91# ??_${ARCH}_foo.${EPATCH_SUFFIX} 207# ??_${ARCH}_foo.${EPATCH_SUFFIX}
208# else
209# *.${EPATCH_SUFFIX}
210# @CODE
211# The leading ?? are typically numbers used to force consistent patch ordering.
212# The arch field is used to apply patches only for the host architecture with
213# the special value of "all" means apply for everyone. Note that using values
214# other than "all" is highly discouraged -- you should apply patches all the
215# time and let architecture details be detected at configure/compile time.
92# 216#
93# For example: 217# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
218# for patches to apply.
94# 219#
95# 01_all_misc-fix.patch.bz2 220# Refer to the other EPATCH_xxx variables for more customization of behavior.
96# 02_sparc_another-fix.patch.bz2
97#
98# This ensures that there are a set order, and you can have ARCH
99# specific patches.
100#
101# If you however give an argument to epatch(), it will treat it as a
102# single patch that need to be applied if its a file. If on the other
103# hand its a directory, it will set EPATCH_SOURCE to this.

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