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!

20# libs in /lib. This is to fix linking problems when you have
21# the .so in /lib, and the .a in /usr/lib. What happens is that
22# in some cases when linking dynamic, the .a in /usr/lib is used
23# instead of the .so in /lib due to gcc/libtool tweaking ld's
24# library search path. This cause many builds to fail.
25# See bug #4411 for more info.

27# To use, simply call:
28#
29# gen_usr_ldscript libfoo.so
30#
31# Note that you should in general use the unversioned name of
32# the library, as ldconfig should usually update it correctly
33# to point to the latest version of the library present.

100# @FUNCTION: eshopts_push
101# @USAGE: [options to `set` or `shopt`]
102# @DESCRIPTION:
103# Often times code will want to enable a shell option to change code behavior.
104# Since changing shell options can easily break other pieces of code (which
105# assume the default state), eshopts_push is used to (1) push the current shell
106# options onto a stack and (2) pass the specified arguments to set.
107#
108# If the first argument is '-s' or '-u', we assume you want to call `shopt`
109# rather than `set` as there are some options only available via that.
110#
111# A common example is to disable shell globbing so that special meaning/care
112# may be used with variables/arguments to custom functions. That would be:
113# @CODE
114# eshopts_push -o noglob
115# for x in ${foo} ; do
116# if ...some check... ; then
117# eshopts_pop
85 return 0 118# return 0

121# eshopts_pop
122# @CODE
123eshopts_push() {
124 # have to assume __ESHOPTS_SAVE__ isn't screwed with
125 # as a `declare -a` here will reset its value
126 local i=${#__ESHOPTS_SAVE__[@]}
127 if [[ $1 == -[su] ]] ; then

106# This function is for bulk patching, or in theory for just one 193# @FUNCTION: epatch
107# or two patches. 194# @USAGE: [patches] [dirs of patches]
195# @DESCRIPTION:
196# epatch is designed to greatly simplify the application of patches. It can
197# process patch files directly, or directories of patches. The patches may be
198# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
199# the -p option as epatch will automatically attempt -p0 to -p5 until things
200# apply successfully.
108# 201#
109# It should work with .bz2, .gz, .zip and plain text patches. 202# If you do not specify any options, then epatch will default to the directory
110# Currently all patches should be the same format. 203# specified by EPATCH_SOURCE.
111# 204#
112# You do not have to specify '-p' option to patch, as it will 205# When processing directories, epatch will apply all patches that match:
113# try with -p0 to -p5 until it succeed, or fail at -p5. 206# @CODE
114# 207# if ${EPATCH_FORCE} != "yes"
115# Above EPATCH_* variables can be used to control various defaults,
116# bug they should be left as is to ensure an ebuild can rely on
117# them for.
118#
119# Patches are applied in current directory.
120#
121# Bulk Patches should preferibly have the form of:
122#
123# ??_${ARCH}_foo.${EPATCH_SUFFIX} 208# ??_${ARCH}_foo.${EPATCH_SUFFIX}
209# else
210# *.${EPATCH_SUFFIX}
211# @CODE
212# The leading ?? are typically numbers used to force consistent patch ordering.
213# The arch field is used to apply patches only for the host architecture with
214# the special value of "all" means apply for everyone. Note that using values
215# other than "all" is highly discouraged -- you should apply patches all the
216# time and let architecture details be detected at configure/compile time.
124# 217#
125# For example: 218# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
219# for patches to apply.
126# 220#
127# 01_all_misc-fix.patch.bz2 221# Refer to the other EPATCH_xxx variables for more customization of behavior.
128# 02_sparc_another-fix.patch.bz2
129#
130# This ensures that there are a set order, and you can have ARCH
131# specific patches.
132#
133# If you however give an argument to epatch(), it will treat it as a
134# single patch that need to be applied if its a file. If on the other
135# hand its a directory, it will set EPATCH_SOURCE to this.

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

728# new convenience patch wrapper function to eventually replace epatch(),
729# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and
730# /usr/bin/patch
731# Features:
732# - bulk patch handling similar to epatch()'s
733# - automatic patch level detection like epatch()'s
734# - automatic patch uncompression like epatch()'s
735# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
736# manually instead
737# - once I decide it's production-ready, it'll be called from base_src_unpack
738# to handle $PATCHES to avoid defining src_unpack just to use xpatch
739
740# accepts zero or more parameters specifying patchfiles and/or patchdirs
741
742# known issues:
743# - only supports unified style patches (does anyone _really_ use anything
744# else?)
745# - because it doesn't use --dry-run there is a risk of it failing
746# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
747# any of the backup heuristics that patch employs to discover a filename.
748# however, this isn't dangerous because if it works for the developer who's
749# writing the ebuild, it'll always work for the users, and if it doesn't,
750# then we'll fix it :-)
751# - no support as yet for patches applying outside $S (and not directly in $WORKDIR).

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

1486#
1487# A temporary hack until portage properly supports DEPENDing on USE
1488# flags being enabled in packages. This will check to see if the specified
1489# DEPEND atom was built with the specified list of USE flags. The
1490# --missing option controls the behavior if called on a package that does
1491# not actually support the defined USE flags (aka listed in IUSE).
1492# The default is to abort (call die). The -a and -o flags control
1493# the requirements of the USE flags. They correspond to "and" and "or"
1494# logic. So the -a flag means all listed USE flags must be enabled
1495# while the -o flag means at least one of the listed IUSE flags must be
1496# enabled. The --hidden option is really for internal use only as it
1497# means the USE flag we're checking is hidden expanded, so it won't be found
1498# in IUSE like normal USE flags.
