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!

17# This function generate linker scripts in /usr/lib for dynamic 22if has "${EAPI:-0}" 0 1 2; then
18# libs in /lib. This is to fix linking problems when you have
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#
25# To use, simply call:
26#
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.

77# @FUNCTION: eshopts_push
78# @USAGE: [options to `set` or `shopt`]
79# @DESCRIPTION:
80# Often times code will want to enable a shell option to change code behavior.
81# Since changing shell options can easily break other pieces of code (which
82# assume the default state), eshopts_push is used to (1) push the current shell
83# options onto a stack and (2) pass the specified arguments to set.
84#
85# If the first argument is '-s' or '-u', we assume you want to call `shopt`
86# rather than `set` as there are some options only available via that.
87#
88# A common example is to disable shell globbing so that special meaning/care
89# may be used with variables/arguments to custom functions. That would be:
90# @CODE
91# eshopts_push -o noglob
92# for x in ${foo} ; do
93# if ...some check... ; then
94# eshopts_pop
83 return 0 95# return 0
96# fi
97# done
98# eshopts_pop

102 # as a `declare -a` here will reset its value

98# This function is for bulk patching, or in theory for just one 170# @FUNCTION: epatch
99# or two patches. 171# @USAGE: [patches] [dirs of patches]
172# @DESCRIPTION:
173# epatch is designed to greatly simplify the application of patches. It can
174# process patch files directly, or directories of patches. The patches may be
175# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
176# the -p option as epatch will automatically attempt -p0 to -p5 until things
177# apply successfully.
100# 178#
101# It should work with .bz2, .gz, .zip and plain text patches. 179# If you do not specify any options, then epatch will default to the directory
102# Currently all patches should be the same format. 180# specified by EPATCH_SOURCE.
103# 181#
104# You do not have to specify '-p' option to patch, as it will 182# When processing directories, epatch will apply all patches that match:
105# try with -p0 to -p5 until it succeed, or fail at -p5. 183# @CODE
106# 184# ${EPATCH_FORCE} == "yes"
107# Above EPATCH_* variables can be used to control various defaults,
108# bug they should be left as is to ensure an ebuild can rely on
109# them for.
110#
111# Patches are applied in current directory.
112#
113# Bulk Patches should preferibly have the form of:
114#
115# ??_${ARCH}_foo.${EPATCH_SUFFIX} 185# ??_${ARCH}_foo.${EPATCH_SUFFIX}
186# else
187# *.${EPATCH_SUFFIX}
188# @CODE
189# The leading ?? are typically numbers used to force consistent patch ordering.
190# The arch field is used to apply patches only for the host architecture with
191# the special value of "all" means apply for everyone. Note that using values
192# other than "all" is highly discouraged -- you should apply patches all the
193# time and let architecture details be detected at configure/compile time.
116# 194#
117# For example: 195# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
196# for patches to apply.
118# 197#
119# 01_all_misc-fix.patch.bz2 198# 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.

1197# strace -elseek <pdv archive>

1201# sometimes the function call is _llseek or something) and steal the 2nd
1202# parameter. Here is an example:
1203#
1204# @CODE
1205# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1206# lseek
1207# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1208# lseek(3, -4, SEEK_END) = 2981250

1768# A temporary hack until portage properly supports DEPENDing on USE
1769# flags being enabled in packages. This will check to see if the specified
1770# DEPEND atom was built with the specified list of USE flags. The
1771# --missing option controls the behavior if called on a package that does
1772# not actually support the defined USE flags (aka listed in IUSE).
1773# The default is to abort (call die). The -a and -o flags control
1774# the requirements of the USE flags. They correspond to "and" and "or"
1775# logic. So the -a flag means all listed USE flags must be enabled
1776# while the -o flag means at least one of the listed IUSE flags must be
1777# enabled. The --hidden option is really for internal use only as it
1778# means the USE flag we're checking is hidden expanded, so it won't be found
1779# in IUSE like normal USE flags.
