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 swegener 1.286 #
15 vapier 1.283 # Due to the nature of this eclass, some functions may have maintainers
16     # different from the overall eclass!

104 vapier 1.330 # @USAGE: [options to `set` or `shopt`]
105 vapier 1.322 # @DESCRIPTION:
106     # Often times code will want to enable a shell option to change code behavior.
107     # Since changing shell options can easily break other pieces of code (which
108     # assume the default state), eshopts_push is used to (1) push the current shell
109     # options onto a stack and (2) pass the specified arguments to set.
110     #
111 vapier 1.330 # If the first argument is '-s' or '-u', we assume you want to call `shopt`
112     # rather than `set` as there are some options only available via that.
113     #
114 vapier 1.322 # A common example is to disable shell globbing so that special meaning/care
115     # may be used with variables/arguments to custom functions. That would be:
116     # @CODE
117     # eshopts_push -o noglob
118     # for x in ${foo} ; do
119     # if ...some check... ; then
120     # eshopts_pop

196 vapier 1.325 # @FUNCTION: epatch
197     # @USAGE: [patches] [dirs of patches]
198     # @DESCRIPTION:
199     # epatch is designed to greatly simplify the application of patches. It can
200     # process patch files directly, or directories of patches. The patches may be
201     # compressed (bzip/gzip/etc...) or plain text. You generally need not specify
202     # the -p option as epatch will automatically attempt -p0 to -p5 until things
203     # apply successfully.
204 azarah 1.2 #
205 vapier 1.325 # If you do not specify any options, then epatch will default to the directory
206     # specified by EPATCH_SOURCE.
207 azarah 1.2 #
208 vapier 1.325 # When processing directories, epatch will apply all patches that match:
209     # @CODE
210 vapier 1.350 # if ${EPATCH_FORCE} != "yes"
211 vapier 1.325 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
212     # else
213     # *.${EPATCH_SUFFIX}
214     # @CODE
215     # The leading ?? are typically numbers used to force consistent patch ordering.
216     # The arch field is used to apply patches only for the host architecture with
217     # the special value of "all" means apply for everyone. Note that using values
218     # other than "all" is highly discouraged -- you should apply patches all the
219     # time and let architecture details be detected at configure/compile time.
220 azarah 1.2 #
221 vapier 1.325 # If EPATCH_SUFFIX is empty, then no period before it is implied when searching
222     # for patches to apply.

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

901     # @USAGE: <file to unpack> <size of off_t>
902     # @DESCRIPTION:
903 vapier 1.70 # Unpack those pesky pdv generated files ...
904     # They're self-unpacking programs with the binary package stuffed in
905     # the middle of the archive. Valve seems to use it a lot ... too bad
906     # it seems to like to segfault a lot :(. So lets take it apart ourselves.
907 swegener 1.286 #
908 vapier 1.283 # You have to specify the off_t size ... I have no idea how to extract that
909     # information out of the binary executable myself. Basically you pass in
910     # the size of the off_t type (in bytes) on the machine that built the pdv
911     # archive.
912 vapier 1.70 #
913 vapier 1.283 # One way to determine this is by running the following commands:
914 ulm 1.288 #
915     # @CODE
916     # strings <pdv archive> | grep lseek
917     # strace -elseek <pdv archive>
918     # @CODE
919     #
920 vapier 1.283 # Basically look for the first lseek command (we do the strings/grep because
921     # sometimes the function call is _llseek or something) and steal the 2nd
922     # parameter. Here is an example:
923 ulm 1.288 #
924     # @CODE
925     # vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
926     # lseek
927     # vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
928     # lseek(3, -4, SEEK_END) = 2981250
929     # @CODE
930     #
931 vapier 1.283 # Thus we would pass in the value of '4' as the second parameter.
