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!

98 # @FUNCTION: eshopts_push
99 # @USAGE: [options to `set` or `shopt`]
100 # @DESCRIPTION:
101 # Often times code will want to enable a shell option to change code behavior.
102 # Since changing shell options can easily break other pieces of code (which
103 # assume the default state), eshopts_push is used to (1) push the current shell
104 # options onto a stack and (2) pass the specified arguments to set.
105 #
106 # If the first argument is '-s' or '-u', we assume you want to call `shopt`
107 # rather than `set` as there are some options only available via that.
108 #
109 # A common example is to disable shell globbing so that special meaning/care
110 # may be used with variables/arguments to custom functions. That would be:
111 # @CODE
112 # eshopts_push -o noglob
113 # for x in ${foo} ; do
114 # if ...some check... ; then
115 # eshopts_pop
116 # return 0
117 # fi
118 # done
119 # eshopts_pop
120 # @CODE
121 eshopts_push() {
122 # have to assume __ESHOPTS_SAVE__ isn't screwed with
123 # as a `declare -a` here will reset its value
124 local i=${#__ESHOPTS_SAVE__[@]}
125 if [[ $1 == -[su] ]] ; then
126 __ESHOPTS_SAVE__[$i]=$(shopt -p)
127 [[ $# -eq 0 ]] && return 0
128 shopt "$@" || die "eshopts_push: bad options to shopt: $*"
129 else
130 __ESHOPTS_SAVE__[$i]=$-
131 [[ $# -eq 0 ]] && return 0
132 set "$@" || die "eshopts_push: bad options to set: $*"
133 fi
134 }
135
136 # @FUNCTION: eshopts_pop
137 # @USAGE:
138 # @DESCRIPTION:
139 # Restore the shell options to the state saved with the corresponding
140 # eshopts_push call. See that function for more details.
141 eshopts_pop() {
142 [[ $# -ne 0 ]] && die "eshopts_pop takes no arguments"
143 local i=$(( ${#__ESHOPTS_SAVE__[@]} - 1 ))

190
191 # @FUNCTION: epatch
192 # @USAGE: [patches] [dirs of patches]
193 # @DESCRIPTION:
194 # epatch is designed to greatly simplify the application of patches. It can
195 # process patch files directly, or directories of patches. The patches may be
196 # compressed (bzip/gzip/etc...) or plain text. You generally need not specify
197 # the -p option as epatch will automatically attempt -p0 to -p5 until things
198 # apply successfully.
199 #
200 # If you do not specify any options, then epatch will default to the directory
201 # specified by EPATCH_SOURCE.
202 #
203 # When processing directories, epatch will apply all patches that match:
204 # @CODE
205 # if ${EPATCH_FORCE} != "yes"
206 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
207 # else
208 # *.${EPATCH_SUFFIX}
209 # @CODE
210 # The leading ?? are typically numbers used to force consistent patch ordering.
211 # The arch field is used to apply patches only for the host architecture with
212 # the special value of "all" means apply for everyone. Note that using values
213 # other than "all" is highly discouraged -- you should apply patches all the
214 # time and let architecture details be detected at configure/compile time.
215 #
216 # If EPATCH_SUFFIX is empty, then no period before it is implied when searching
217 # for patches to apply.
218 #
219 # Refer to the other EPATCH_xxx variables for more customization of behavior.
220 epatch() {
221 _epatch_draw_line() {

1244 # Unpack those pesky pdv generated files ...
1245 # They're self-unpacking programs with the binary package stuffed in
1246 # the middle of the archive. Valve seems to use it a lot ... too bad
1247 # it seems to like to segfault a lot :(. So lets take it apart ourselves.
1248 #
1249 # You have to specify the off_t size ... I have no idea how to extract that
1250 # information out of the binary executable myself. Basically you pass in
1251 # the size of the off_t type (in bytes) on the machine that built the pdv
1252 # archive.
1253 #
1254 # One way to determine this is by running the following commands:
1255 #
1256 # @CODE
1257 # strings <pdv archive> | grep lseek
1258 # strace -elseek <pdv archive>
1259 # @CODE
1260 #
1261 # Basically look for the first lseek command (we do the strings/grep because
1262 # sometimes the function call is _llseek or something) and steal the 2nd
1263 # parameter. Here is an example:
1264 #
1265 # @CODE
1266 # vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1267 # lseek
1268 # vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1269 # lseek(3, -4, SEEK_END) = 2981250
1270 # @CODE
1271 #
1272 # Thus we would pass in the value of '4' as the second parameter.

1831 # A temporary hack until portage properly supports DEPENDing on USE
1832 # flags being enabled in packages. This will check to see if the specified
1833 # DEPEND atom was built with the specified list of USE flags. The

1837 # the requirements of the USE flags. They correspond to "and" and "or"

1839 # while the -o flag means at least one of the listed IUSE flags must be
1840 # enabled. The --hidden option is really for internal use only as it
1841 # means the USE flag we're checking is hidden expanded, so it won't be found
