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!

73# @FUNCTION: eshopts_push
74# @USAGE: [options to `set`]
75# @DESCRIPTION:
76# Often times code will want to enable a shell option to change code behavior.
77# Since changing shell options can easily break other pieces of code (which
78# assume the default state), eshopts_push is used to (1) push the current shell
79# options onto a stack and (2) pass the specified arguments to set.
24# 80#
25# To use, simply call: 81# A common example is to disable shell globbing so that special meaning/care
82# may be used with variables/arguments to custom functions. That would be:
83# @CODE
84# eshopts_push -o noglob
85# for x in ${foo} ; do
86# if ...some check... ; then
87# eshopts_pop
88# return 0
89# fi
90# done
91# eshopts_pop
92# @CODE
93eshopts_push() {
94 # have to assume __ESHOPTS_SAVE__ isn't screwed with
95 # as a `declare -a` here will reset its value
96 local i=${#__ESHOPTS_SAVE__[@]}

98 [[ $# -eq 0 ]] && return 0
99 set "$@" || die "eshopts_push: bad options to set: $*"
100}

102# @FUNCTION: eshopts_pop
103# @USAGE:
104# @DESCRIPTION:
105# Restore the shell options to the state saved with the corresponding
106# eshopts_push call. See that function for more details.
107eshopts_pop() {
108 [[ $# -ne 0 ]] && die "eshopts_pop takes no arguments"

30# the library, as ldconfig should usually update it correctly 138
31# to point to the latest version of the library present. 139# This function is for bulk patching, or in theory for just one
140# or two patches.
32# 141#
142# It should work with .bz2, .gz, .zip and plain text patches.
143# Currently all patches should be the same format.
144#
145# You do not have to specify '-p' option to patch, as it will
146# try with -p0 to -p5 until it succeed, or fail at -p5.
147#
148# Above EPATCH_* variables can be used to control various defaults,
149# bug they should be left as is to ensure an ebuild can rely on
150# them for.
151#
152# Patches are applied in current directory.
153#
154# Bulk Patches should preferably have the form of:
155#
156# ??_${ARCH}_foo.${EPATCH_SUFFIX}
157#
158# For example:
159#
160# 01_all_misc-fix.patch.bz2
161# 02_sparc_another-fix.patch.bz2
162#
163# This ensures that there are a set order, and you can have ARCH
164# specific patches.
165#
166# If you however give an argument to epatch(), it will treat it as a
167# single patch that need to be applied if its a file. If on the other
168# hand its a directory, it will set EPATCH_SOURCE to this.

1176# @DESCRIPTION:
1177# Unpack those pesky pdv generated files ...
1178# They're self-unpacking programs with the binary package stuffed in
1179# the middle of the archive. Valve seems to use it a lot ... too bad
1180# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1181#
1182# You have to specify the off_t size ... I have no idea how to extract that
1183# information out of the binary executable myself. Basically you pass in
1184# the size of the off_t type (in bytes) on the machine that built the pdv
1185# archive.
1186#
1187# One way to determine this is by running the following commands:
1188#
1189# @CODE
1190# strings <pdv archive> | grep lseek
1191# strace -elseek <pdv archive>
1192# @CODE
1193#
1194# Basically look for the first lseek command (we do the strings/grep because
1195# sometimes the function call is _llseek or something) and steal the 2nd
1196# parameter. Here is an example:
1197#
1198# @CODE
1199# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1200# lseek
1201# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1202# lseek(3, -4, SEEK_END) = 2981250
1203# @CODE
1204#
1205# Thus we would pass in the value of '4' as the second parameter.

1759# A temporary hack until portage properly supports DEPENDing on USE
1760# flags being enabled in packages. This will check to see if the specified
1761# DEPEND atom was built with the specified list of USE flags. The
1762# --missing option controls the behavior if called on a package that does
1763# not actually support the defined USE flags (aka listed in IUSE).
1764# The default is to abort (call die). The -a and -o flags control
1765# the requirements of the USE flags. They correspond to "and" and "or"
1766# logic. So the -a flag means all listed USE flags must be enabled
1767# while the -o flag means at least one of the listed IUSE flags must be
1768# enabled. The --hidden option is really for internal use only as it
1769# means the USE flag we're checking is hidden expanded, so it won't be found
1770# in IUSE like normal USE flags.
