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.

87# @FUNCTION: eshopts_push
88# @USAGE: [options to `set` or `shopt`]
89# @DESCRIPTION:
90# Often times code will want to enable a shell option to change code behavior.
91# Since changing shell options can easily break other pieces of code (which
92# assume the default state), eshopts_push is used to (1) push the current shell
93# options onto a stack and (2) pass the specified arguments to set.
94#
95# If the first argument is '-s' or '-u', we assume you want to call `shopt`
96# rather than `set` as there are some options only available via that.
97#
98# A common example is to disable shell globbing so that special meaning/care
99# may be used with variables/arguments to custom functions. That would be:
100# @CODE
101# eshopts_push -o noglob
102# for x in ${foo} ; do
103# if ...some check... ; then
104# eshopts_pop
105# return 0
106# fi
107# done
108# eshopts_pop
109# @CODE
110eshopts_push() {
111 # have to assume __ESHOPTS_SAVE__ isn't screwed with
112 # as a `declare -a` here will reset its value
113 local i=${#__ESHOPTS_SAVE__[@]}
114 if [[ $1 == -[su] ]] ; then
115 __ESHOPTS_SAVE__[$i]=$(shopt -p)

180# @FUNCTION: epatch
181# @USAGE: [patches] [dirs of patches]
182# @DESCRIPTION:
183# epatch is designed to greatly simplify the application of patches. It can
184# process patch files directly, or directories of patches. The patches may be
185# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
186# the -p option as epatch will automatically attempt -p0 to -p5 until things
187# apply successfully.
188#
189# If you do not specify any options, then epatch will default to the directory
190# specified by EPATCH_SOURCE.
191#
192# When processing directories, epatch will apply all patches that match:
193# @CODE
194# ${EPATCH_FORCE} == "yes"
195# ??_${ARCH}_foo.${EPATCH_SUFFIX}
196# else
197# *.${EPATCH_SUFFIX}
198# @CODE
199# The leading ?? are typically numbers used to force consistent patch ordering.
200# The arch field is used to apply patches only for the host architecture with
201# the special value of "all" means apply for everyone. Note that using values
202# other than "all" is highly discouraged -- you should apply patches all the
203# time and let architecture details be detected at configure/compile time.
204#
205# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
206# for patches to apply.
207#
208# Refer to the other EPATCH_xxx variables for more customization of behavior.

1211# Unpack those pesky pdv generated files ...
1212# They're self-unpacking programs with the binary package stuffed in
1213# the middle of the archive. Valve seems to use it a lot ... too bad
1214# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1215#
1216# You have to specify the off_t size ... I have no idea how to extract that
1217# information out of the binary executable myself. Basically you pass in
1218# the size of the off_t type (in bytes) on the machine that built the pdv
1219# archive.
1220#
1221# One way to determine this is by running the following commands:
1222#
1223# @CODE
1224# strings <pdv archive> | grep lseek
1225# strace -elseek <pdv archive>
1226# @CODE
1227#
1228# Basically look for the first lseek command (we do the strings/grep because
1229# sometimes the function call is _llseek or something) and steal the 2nd
1230# parameter. Here is an example:
1231#
1232# @CODE
1233# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1234# lseek
1235# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1236# lseek(3, -4, SEEK_END) = 2981250
1237# @CODE
1238#
1239# Thus we would pass in the value of '4' as the second parameter.

1796# A temporary hack until portage properly supports DEPENDing on USE
1797# flags being enabled in packages. This will check to see if the specified
1798# DEPEND atom was built with the specified list of USE flags. The
1799# --missing option controls the behavior if called on a package that does
1800# not actually support the defined USE flags (aka listed in IUSE).
1801# The default is to abort (call die). The -a and -o flags control
1802# the requirements of the USE flags. They correspond to "and" and "or"
1803# logic. So the -a flag means all listed USE flags must be enabled
1804# while the -o flag means at least one of the listed IUSE flags must be
1805# enabled. The --hidden option is really for internal use only as it
1806# means the USE flag we're checking is hidden expanded, so it won't be found
1807# in IUSE like normal USE flags.
