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!

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.

154# Often times code will want to enable a shell option to change code behavior.
155# Since changing shell options can easily break other pieces of code (which
156# assume the default state), eshopts_push is used to (1) push the current shell
157# options onto a stack and (2) pass the specified arguments to set.
158#
159# If the first argument is '-s' or '-u', we assume you want to call `shopt`
160# rather than `set` as there are some options only available via that.
161#
162# A common example is to disable shell globbing so that special meaning/care
163# may be used with variables/arguments to custom functions. That would be:
164# @CODE
165# eshopts_push -o noglob

100# This function is for bulk patching, or in theory for just one 260# @FUNCTION: epatch
101# or two patches. 261# @USAGE: [patches] [dirs of patches]
262# @DESCRIPTION:
263# epatch is designed to greatly simplify the application of patches. It can
264# process patch files directly, or directories of patches. The patches may be
265# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
266# the -p option as epatch will automatically attempt -p0 to -p5 until things
267# apply successfully.
102# 268#
103# It should work with .bz2, .gz, .zip and plain text patches. 269# If you do not specify any options, then epatch will default to the directory
104# Currently all patches should be the same format. 270# specified by EPATCH_SOURCE.
105# 271#
106# You do not have to specify '-p' option to patch, as it will 272# When processing directories, epatch will apply all patches that match:
107# try with -p0 to -p5 until it succeed, or fail at -p5. 273# @CODE
108# 274# if ${EPATCH_FORCE} != "yes"
109# Above EPATCH_* variables can be used to control various defaults,
110# bug they should be left as is to ensure an ebuild can rely on
111# them for.
112#
113# Patches are applied in current directory.
114#
115# Bulk Patches should preferibly have the form of:
116#
117# ??_${ARCH}_foo.${EPATCH_SUFFIX} 275# ??_${ARCH}_foo.${EPATCH_SUFFIX}
276# else
277# *.${EPATCH_SUFFIX}
278# @CODE
279# The leading ?? are typically numbers used to force consistent patch ordering.
280# The arch field is used to apply patches only for the host architecture with
281# the special value of "all" means apply for everyone. Note that using values
282# other than "all" is highly discouraged -- you should apply patches all the
283# time and let architecture details be detected at configure/compile time.
118# 284#
119# For example: 285# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
286# for patches to apply.
120# 287#
121# 01_all_misc-fix.patch.bz2 288# Refer to the other EPATCH_xxx variables for more customization of behavior.
122# 02_sparc_another-fix.patch.bz2
123#
124# This ensures that there are a set order, and you can have ARCH
125# specific patches.
126#
127# If you however give an argument to epatch(), it will treat it as a
128# single patch that need to be applied if its a file. If on the other
129# hand its a directory, it will set EPATCH_SOURCE to this.

518# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
519# of these three directories to exist will be the one to use, ignoring
520# any more general directories which might exist as well.
521#
522# User patches are intended for quick testing of patches without ebuild
523# modifications, as well as for permanent customizations a user might
524# desire. Obviously, there can be no official support for arbitrarily
525# patched ebuilds. So whenever a build log in a bug report mentions that
526# user patches were applied, the user should be asked to reproduce the
527# problem without these.
528#
529# Not all ebuilds do call this function, so placing patches in the
530# stated directory might or might not work, depending on the package and
531# the eclasses it inherits and uses. It is safe to call the function
532# repeatedly, so it is always possible to add a call at the ebuild
533# level. The first call is the time when the patches will be
534# applied.
535#
536# Ideally, this function should be called after gentoo-specific patches
537# have been applied, so that their code can be modified as well, but
538# before calls to e.g. eautoreconf, as the user patches might affect

974# the size of the off_t type (in bytes) on the machine that built the pdv

988# @CODE

991# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
992# lseek(3, -4, SEEK_END) = 2981250

1490# @USAGE: [--hidden] [--missing <action>] [-a|-o] <DEPEND ATOM> <List of USE flags>
1491# @DESCRIPTION:
1492#
1493# Deprecated: Use EAPI 2 use deps in DEPEND|RDEPEND and with has_version calls.
1494#
1495# A temporary hack until portage properly supports DEPENDing on USE
1496# flags being enabled in packages. This will check to see if the specified
1497# DEPEND atom was built with the specified list of USE flags. The
1498# --missing option controls the behavior if called on a package that does
1499# not actually support the defined USE flags (aka listed in IUSE).
1500# The default is to abort (call die). The -a and -o flags control
1501# the requirements of the USE flags. They correspond to "and" and "or"
1502# logic. So the -a flag means all listed USE flags must be enabled
1503# while the -o flag means at least one of the listed IUSE flags must be
1504# enabled. The --hidden option is really for internal use only as it
1505# means the USE flag we're checking is hidden expanded, so it won't be found
1506# in IUSE like normal USE flags.
1507#
1508# Remember that this function isn't terribly intelligent so order of optional
1509# flags matter.
