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!

50# in some cases when linking dynamic, the .a in /usr/lib is used

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

138# This function is for bulk patching, or in theory for just one 265# @FUNCTION: epatch
139# or two patches. 266# @USAGE: [options] [patches] [dirs of patches]
267# @DESCRIPTION:
268# epatch is designed to greatly simplify the application of patches. It can
269# process patch files directly, or directories of patches. The patches may be
270# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
271# the -p option as epatch will automatically attempt -p0 to -p5 until things
272# apply successfully.
140# 273#
141# It should work with .bz2, .gz, .zip and plain text patches. 274# If you do not specify any patches/dirs, then epatch will default to the
142# Currently all patches should be the same format. 275# directory specified by EPATCH_SOURCE.
143# 276#
144# You do not have to specify '-p' option to patch, as it will 277# Any options specified that start with a dash will be passed down to patch
145# try with -p0 to -p5 until it succeed, or fail at -p5. 278# for this specific invocation. As soon as an arg w/out a dash is found, then
279# arg processing stops.
146# 280#
147# Above EPATCH_* variables can be used to control various defaults, 281# When processing directories, epatch will apply all patches that match:
148# bug they should be left as is to ensure an ebuild can rely on 282# @CODE
149# them for. 283# if ${EPATCH_FORCE} != "yes"
150#
151# Patches are applied in current directory.
152#
153# Bulk Patches should preferibly have the form of:
154#
155# ??_${ARCH}_foo.${EPATCH_SUFFIX} 284# ??_${ARCH}_foo.${EPATCH_SUFFIX}
285# else
286# *.${EPATCH_SUFFIX}
287# @CODE
288# The leading ?? are typically numbers used to force consistent patch ordering.
289# The arch field is used to apply patches only for the host architecture with
290# the special value of "all" means apply for everyone. Note that using values
291# other than "all" is highly discouraged -- you should apply patches all the
292# time and let architecture details be detected at configure/compile time.
156# 293#
157# For example: 294# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
295# for patches to apply.
158# 296#
159# 01_all_misc-fix.patch.bz2 297# Refer to the other EPATCH_xxx variables for more customization of behavior.
160# 02_sparc_another-fix.patch.bz2
161#
162# This ensures that there are a set order, and you can have ARCH
163# specific patches.
164#
165# If you however give an argument to epatch(), it will treat it as a
166# single patch that need to be applied if its a file. If on the other
167# hand its a directory, it will set EPATCH_SOURCE to this.

552# @DESCRIPTION:
553# Applies user-provided patches to the source tree. The patches are
554# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>[:SLOT]/, where the first
555# of these three directories to exist will be the one to use, ignoring
556# any more general directories which might exist as well. They must end
557# in ".patch" to be applied.
558#
559# User patches are intended for quick testing of patches without ebuild
560# modifications, as well as for permanent customizations a user might
561# desire. Obviously, there can be no official support for arbitrarily
562# patched ebuilds. So whenever a build log in a bug report mentions that
563# user patches were applied, the user should be asked to reproduce the
564# problem without these.
565#
566# Not all ebuilds do call this function, so placing patches in the
567# stated directory might or might not work, depending on the package and
568# the eclasses it inherits and uses. It is safe to call the function
569# repeatedly, so it is always possible to add a call at the ebuild
570# level. The first call is the time when the patches will be
571# applied.
572#
573# Ideally, this function should be called after gentoo-specific patches
574# have been applied, so that their code can be modified as well, but
575# before calls to e.g. eautoreconf, as the user patches might affect
576# autotool input files as well.

963#
964# Usage: unpack_pdv [file to unpack] [size of off_t]
965# - you have to specify the off_t size ... i have no idea how to extract that
966# information out of the binary executable myself. basically you pass in
967# the size of the off_t type (in bytes) on the machine that built the pdv
968# archive. one way to determine this is by running the following commands:
969# strings <pdv archive> | grep lseek
970# strace -elseek <pdv archive>
971# basically look for the first lseek command (we do the strings/grep because
972# sometimes the function call is _llseek or something) and steal the 2nd
973# parameter. here is an example:
974# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
975# lseek
976# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
977# lseek(3, -4, SEEK_END) = 2981250
978# thus we would pass in the value of '4' as the second parameter.

1383# @USAGE: [--all]
1384# @DESCRIPTION:
1385# Locate unnecessary libtool files (.la) and libtool static archives
1386# (.a) and remove them from installation image.
1387#
1388# By default, .la files are removed whenever the static linkage can
1389# either be performed using pkg-config or doesn't introduce additional
1390# flags.
1391#
1392# If '--all' argument is passed, all .la files are removed. This is
1393# usually useful when the package installs plugins and does not use .la
1394# files for loading them.
1395#
1396# The .a files are only removed whenever corresponding .la files state
1397# that they should not be linked to, i.e. whenever these files
1398# correspond to plugins.
1399#
1400# Note: if your package installs both static libraries and .pc files,
1401# you need to add pkg-config to your DEPEND.
