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!

762# new convenience patch wrapper function to eventually replace epatch(),
763# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and
764# /usr/bin/patch
765# Features:
766# - bulk patch handling similar to epatch()'s
767# - automatic patch level detection like epatch()'s
768# - automatic patch uncompression like epatch()'s
769# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
770# manually instead
771# - once I decide it's production-ready, it'll be called from base_src_unpack
772# to handle $PATCHES to avoid defining src_unpack just to use xpatch
773
774# accepts zero or more parameters specifying patchfiles and/or patchdirs
775
776# known issues:
777# - only supports unified style patches (does anyone _really_ use anything
778# else?)
779# - because it doesn't use --dry-run there is a risk of it failing
780# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
781# any of the backup heuristics that patch employs to discover a filename.
782# however, this isn't dangerous because if it works for the developer who's
783# writing the ebuild, it'll always work for the users, and if it doesn't,
784# then we'll fix it :-)
785# - no support as yet for patches applying outside $S (and not directly in $WORKDIR).

1061# the middle of the archive. Valve seems to use it a lot ... too bad
1062# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1063#
1064# You have to specify the off_t size ... I have no idea how to extract that
1065# information out of the binary executable myself. Basically you pass in
1066# the size of the off_t type (in bytes) on the machine that built the pdv

1068#
1069# One way to determine this is by running the following commands:

1073# strace -elseek <pdv archive>
1074# @CODE

1077# sometimes the function call is _llseek or something) and steal the 2nd
1078# parameter. Here is an example:
1079#
1080# @CODE
1081# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1082# lseek
1083# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1084# lseek(3, -4, SEEK_END) = 2981250
1085# @CODE

1628# A temporary hack until portage properly supports DEPENDing on USE
1629# flags being enabled in packages. This will check to see if the specified
1630# DEPEND atom was built with the specified list of USE flags. The
1631# --missing option controls the behavior if called on a package that does
1632# not actually support the defined USE flags (aka listed in IUSE).
1633# The default is to abort (call die). The -a and -o flags control
1634# the requirements of the USE flags. They correspond to "and" and "or"
1635# logic. So the -a flag means all listed USE flags must be enabled
1636# while the -o flag means at least one of the listed fIUSE flags must be
1637# enabled. The --hidden option is really for internal use only as it
1638# means the USE flag we're checking is hidden expanded, so it won't be found
1639# in IUSE like normal USE flags.
