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!

46# This function generate linker scripts in /usr/lib for dynamic 55else
47# libs in /lib. This is to fix linking problems when you have
48# the .so in /lib, and the .a in /usr/lib. What happens is that
49# in some cases when linking dynamic, the .a in /usr/lib is used
50# instead of the .so in /lib due to gcc/libtool tweaking ld's
51# library search path. This cause many builds to fail.
52# See bug #4411 for more info.
53#
54# To use, simply call:
55#
56# gen_usr_ldscript libfoo.so
57#
58# Note that you should in general use the unversioned name of
59# the library, as ldconfig should usually update it correctly
60# to point to the latest version of the library present.

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

137# This function is for bulk patching, or in theory for just one 270# @FUNCTION: epatch
138# 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.
139# 278#
140# 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
141# Currently all patches should be the same format. 280# directory specified by EPATCH_SOURCE.
142# 281#
143# 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
144# 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.
145# 285#
146# Above EPATCH_* variables can be used to control various defaults, 286# When processing directories, epatch will apply all patches that match:
147# bug they should be left as is to ensure an ebuild can rely on 287# @CODE
148# them for. 288# if ${EPATCH_FORCE} != "yes"
149#
150# Patches are applied in current directory.
151#
152# Bulk Patches should preferibly have the form of:
153#
154# ??_${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.
155# 298#
156# For example: 299# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
300# for patches to apply.
157# 301#
158# 01_all_misc-fix.patch.bz2 302# Refer to the other EPATCH_xxx variables for more customization of behavior.
159# 02_sparc_another-fix.patch.bz2
160#
161# This ensures that there are a set order, and you can have ARCH
162# specific patches.
163#
164# If you however give an argument to epatch(), it will treat it as a
165# single patch that need to be applied if its a file. If on the other
166# hand its a directory, it will set EPATCH_SOURCE to this.

575# Applies user-provided patches to the source tree. The patches are
576# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>[:SLOT]/, where the first
577# of these three directories to exist will be the one to use, ignoring
578# any more general directories which might exist as well. They must end
579# in ".patch" to be applied.
580#
581# User patches are intended for quick testing of patches without ebuild
582# modifications, as well as for permanent customizations a user might
583# desire. Obviously, there can be no official support for arbitrarily
584# patched ebuilds. So whenever a build log in a bug report mentions that
585# user patches were applied, the user should be asked to reproduce the
586# problem without these.
587#
588# Not all ebuilds do call this function, so placing patches in the
589# stated directory might or might not work, depending on the package and
590# the eclasses it inherits and uses. It is safe to call the function
591# repeatedly, so it is always possible to add a call at the ebuild
592# level. The first call is the time when the patches will be
593# applied.
594#
595# Ideally, this function should be called after gentoo-specific patches
596# have been applied, so that their code can be modified as well, but
597# before calls to e.g. eautoreconf, as the user patches might affect
598# autotool input files as well.

996# the size of the off_t type (in bytes) on the machine that built the pdv
997# archive. one way to determine this is by running the following commands:
998# strings <pdv archive> | grep lseek
999# strace -elseek <pdv archive>
1000# basically look for the first lseek command (we do the strings/grep because
1001# sometimes the function call is _llseek or something) and steal the 2nd
1002# parameter. here is an example:
1003# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1004# lseek
1005# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin

1425# flags.

1429# plugins and the plugin loader does not use .la files.

1431# If '--all' argument is passed, all .la files are removed without
1432# performing any heuristic on them. You shouldn't ever use that,
1433# and instead report a bug in the algorithm instead.
1434#
1435# The .a files are only removed whenever corresponding .la files state
1436# that they should not be linked to, i.e. whenever these files
1437# correspond to plugins.
1438#
