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!

220# @FUNCTION: eshopts_push
221# @USAGE: [options to `set` or `shopt`]
222# @DESCRIPTION:
223# Often times code will want to enable a shell option to change code behavior.
224# Since changing shell options can easily break other pieces of code (which
225# assume the default state), eshopts_push is used to (1) push the current shell
226# options onto a stack and (2) pass the specified arguments to set.
227#
228# If the first argument is '-s' or '-u', we assume you want to call `shopt`
229# rather than `set` as there are some options only available via that.
230#
231# A common example is to disable shell globbing so that special meaning/care
232# may be used with variables/arguments to custom functions. That would be:
233# @CODE
234# eshopts_push -s noglob
235# for x in ${foo} ; do

169# This function is for bulk patching, or in theory for just one 353# @FUNCTION: epatch
170# or two patches. 354# @USAGE: [options] [patches] [dirs of patches]
355# @DESCRIPTION:
356# epatch is designed to greatly simplify the application of patches. It can
357# process patch files directly, or directories of patches. The patches may be
358# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
359# the -p option as epatch will automatically attempt -p0 to -p4 until things
360# apply successfully.
171# 361#
172# It should work with .bz2, .gz, .zip and plain text patches. 362# If you do not specify any patches/dirs, then epatch will default to the
173# Currently all patches should be the same format. 363# directory specified by EPATCH_SOURCE.
174# 364#
175# You do not have to specify '-p' option to patch, as it will 365# Any options specified that start with a dash will be passed down to patch
176# try with -p0 to -p5 until it succeed, or fail at -p5. 366# for this specific invocation. As soon as an arg w/out a dash is found, then
367# arg processing stops.
177# 368#
178# Above EPATCH_* variables can be used to control various defaults, 369# When processing directories, epatch will apply all patches that match:
179# bug they should be left as is to ensure an ebuild can rely on 370# @CODE
180# them for. 371# if ${EPATCH_FORCE} != "yes"
181#
182# Patches are applied in current directory.
183#
184# Bulk Patches should preferibly have the form of:
185#
186# ??_${ARCH}_foo.${EPATCH_SUFFIX} 372# ??_${ARCH}_foo.${EPATCH_SUFFIX}
373# else
374# *.${EPATCH_SUFFIX}
375# @CODE
376# The leading ?? are typically numbers used to force consistent patch ordering.
377# The arch field is used to apply patches only for the host architecture with
378# the special value of "all" means apply for everyone. Note that using values
379# other than "all" is highly discouraged -- you should apply patches all the
380# time and let architecture details be detected at configure/compile time.
187# 381#
188# For example: 382# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
383# for patches to apply.
189# 384#
190# 01_all_misc-fix.patch.bz2 385# Refer to the other EPATCH_xxx variables for more customization of behavior.
191# 02_sparc_another-fix.patch.bz2
192#
193# This ensures that there are a set order, and you can have ARCH
194# specific patches.
195#
196# If you however give an argument to epatch(), it will treat it as a
197# single patch that need to be applied if its a file. If on the other
198# hand its a directory, it will set EPATCH_SOURCE to this.

664# any more general directories which might exist as well. They must end
665# in ".patch" to be applied.
666#
667# User patches are intended for quick testing of patches without ebuild
668# modifications, as well as for permanent customizations a user might
669# desire. Obviously, there can be no official support for arbitrarily
670# patched ebuilds. So whenever a build log in a bug report mentions that
671# user patches were applied, the user should be asked to reproduce the
672# problem without these.
673#
674# Not all ebuilds do call this function, so placing patches in the
675# stated directory might or might not work, depending on the package and
676# the eclasses it inherits and uses. It is safe to call the function
677# repeatedly, so it is always possible to add a call at the ebuild
678# level. The first call is the time when the patches will be
679# applied.

946# sometimes the function call is _llseek or something) and steal the 2nd
947# parameter. here is an example:
948# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
949# lseek
950# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin

1508#
1509# By default, .la files are removed whenever the static linkage can
1510# either be performed using pkg-config or doesn't introduce additional
1511# flags.
1512#
1513# If '--modules' argument is passed, .la files for modules (plugins) are
1514# removed as well. This is usually useful when the package installs
1515# plugins and the plugin loader does not use .la files.
1516#
1517# If '--all' argument is passed, all .la files are removed without
1518# performing any heuristic on them. You shouldn't ever use that,
1519# and instead report a bug in the algorithm instead.
1520#
1521# The .a files are only removed whenever corresponding .la files state
1522# that they should not be linked to, i.e. whenever these files
1523# correspond to plugins.
1524#
1525# Note: if your package installs both static libraries and .pc files
1526# which use variable substitution for -l flags, you need to add
1527# pkg-config to your DEPEND.
