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!

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

139# This function is for bulk patching, or in theory for just one 270# @FUNCTION: epatch
140# or two patches. 271# @USAGE: [options] [patches] [dirs of patches]
272# @DESCRIPTION:
273# epatch is designed to greatly simplify the application of patches. It can
274# process patch files directly, or directories of patches. The patches may be
275# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
276# the -p option as epatch will automatically attempt -p0 to -p5 until things
277# apply successfully.
141# 278#
142# It should work with .bz2, .gz, .zip and plain text patches. 279# If you do not specify any patches/dirs, then epatch will default to the
143# Currently all patches should be the same format. 280# directory specified by EPATCH_SOURCE.
144# 281#
145# You do not have to specify '-p' option to patch, as it will 282# Any options specified that start with a dash will be passed down to patch
146# try with -p0 to -p5 until it succeed, or fail at -p5. 283# for this specific invocation. As soon as an arg w/out a dash is found, then
284# arg processing stops.
147# 285#
148# Above EPATCH_* variables can be used to control various defaults, 286# When processing directories, epatch will apply all patches that match:
149# bug they should be left as is to ensure an ebuild can rely on 287# @CODE
150# them for. 288# if ${EPATCH_FORCE} != "yes"
151#
152# Patches are applied in current directory.
153#
154# Bulk Patches should preferibly have the form of:
155#
156# ??_${ARCH}_foo.${EPATCH_SUFFIX} 289# ??_${ARCH}_foo.${EPATCH_SUFFIX}
290# else
291# *.${EPATCH_SUFFIX}
292# @CODE
293# The leading ?? are typically numbers used to force consistent patch ordering.
294# The arch field is used to apply patches only for the host architecture with
295# the special value of "all" means apply for everyone. Note that using values
296# other than "all" is highly discouraged -- you should apply patches all the
297# time and let architecture details be detected at configure/compile time.
157# 298#
158# For example: 299# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
300# for patches to apply.
159# 301#
160# 01_all_misc-fix.patch.bz2 302# Refer to the other EPATCH_xxx variables for more customization of behavior.
161# 02_sparc_another-fix.patch.bz2
162#
163# This ensures that there are a set order, and you can have ARCH
164# specific patches.
165#
166# If you however give an argument to epatch(), it will treat it as a
167# single patch that need to be applied if its a file. If on the other
168# hand its a directory, it will set EPATCH_SOURCE to this.

569# @DESCRIPTION:
570# Applies user-provided patches to the source tree. The patches are
571# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>[:SLOT]/, where the first
572# of these three directories to exist will be the one to use, ignoring
573# any more general directories which might exist as well. They must end
574# in ".patch" to be applied.
575#
576# User patches are intended for quick testing of patches without ebuild
577# modifications, as well as for permanent customizations a user might
578# desire. Obviously, there can be no official support for arbitrarily
579# patched ebuilds. So whenever a build log in a bug report mentions that
580# user patches were applied, the user should be asked to reproduce the
581# problem without these.
582#
583# Not all ebuilds do call this function, so placing patches in the
584# stated directory might or might not work, depending on the package and
585# the eclasses it inherits and uses. It is safe to call the function
586# repeatedly, so it is always possible to add a call at the ebuild
587# level. The first call is the time when the patches will be
588# applied.
589#
590# Ideally, this function should be called after gentoo-specific patches
591# have been applied, so that their code can be modified as well, but
592# before calls to e.g. eautoreconf, as the user patches might affect

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

1415# Locate unnecessary libtool files (.la) and libtool static archives
1416# (.a) and remove them from installation image.
1417#
1418# By default, .la files are removed whenever the static linkage can
1419# either be performed using pkg-config or doesn't introduce additional
1420# flags.
1421#
1422# If '--modules' argument is passed, .la files for modules (plugins) are
1423# removed as well. This is usually useful when the package installs
1424# plugins and the plugin loader does not use .la files.
1425#
1426# If '--all' argument is passed, all .la files are removed without
1427# performing any heuristic on them. You shouldn't ever use that,
1428# and instead report a bug in the algorithm instead.
1429#
1430# The .a files are only removed whenever corresponding .la files state
1431# that they should not be linked to, i.e. whenever these files
1432# correspond to plugins.
1433#
1434# Note: if your package installs both static libraries and .pc files
1435# which use variable substitution for -l flags, you need to add
1436# pkg-config to your DEPEND.
