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!

47# This function generate linker scripts in /usr/lib for dynamic 57else
48# libs in /lib. This is to fix linking problems when you have
49# the .so in /lib, and the .a in /usr/lib. What happens is that
50# in some cases when linking dynamic, the .a in /usr/lib is used

59# Note that you should in general use the unversioned name of

151# @FUNCTION: eshopts_push
152# @USAGE: [options to `set` or `shopt`]
153# @DESCRIPTION:
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 -s noglob
166# for x in ${foo} ; do
167# if ...some check... ; then
168# eshopts_pop

131# This function is for bulk patching, or in theory for just one 267# @FUNCTION: epatch
132# or two patches. 268# @USAGE: [options] [patches] [dirs of patches]
269# @DESCRIPTION:
270# epatch is designed to greatly simplify the application of patches. It can
271# process patch files directly, or directories of patches. The patches may be
272# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
273# the -p option as epatch will automatically attempt -p0 to -p5 until things
274# apply successfully.
133# 275#
134# It should work with .bz2, .gz, .zip and plain text patches. 276# If you do not specify any patches/dirs, then epatch will default to the
135# Currently all patches should be the same format. 277# directory specified by EPATCH_SOURCE.
136# 278#
137# You do not have to specify '-p' option to patch, as it will 279# Any options specified that start with a dash will be passed down to patch
138# try with -p0 to -p5 until it succeed, or fail at -p5. 280# for this specific invocation. As soon as an arg w/out a dash is found, then
281# arg processing stops.
139# 282#
140# Above EPATCH_* variables can be used to control various defaults, 283# When processing directories, epatch will apply all patches that match:
141# bug they should be left as is to ensure an ebuild can rely on 284# @CODE
142# them for. 285# if ${EPATCH_FORCE} != "yes"
143#
144# Patches are applied in current directory.
145#
146# Bulk Patches should preferibly have the form of:
147#
148# ??_${ARCH}_foo.${EPATCH_SUFFIX} 286# ??_${ARCH}_foo.${EPATCH_SUFFIX}
287# else
288# *.${EPATCH_SUFFIX}
289# @CODE
290# The leading ?? are typically numbers used to force consistent patch ordering.
291# The arch field is used to apply patches only for the host architecture with
292# the special value of "all" means apply for everyone. Note that using values
293# other than "all" is highly discouraged -- you should apply patches all the
294# time and let architecture details be detected at configure/compile time.
149# 295#
150# For example: 296# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
297# for patches to apply.
151# 298#
152# 01_all_misc-fix.patch.bz2 299# Refer to the other EPATCH_xxx variables for more customization of behavior.
153# 02_sparc_another-fix.patch.bz2
154#
155# This ensures that there are a set order, and you can have ARCH
156# specific patches.
157#
158# If you however give an argument to epatch(), it will treat it as a
159# single patch that need to be applied if its a file. If on the other
160# hand its a directory, it will set EPATCH_SOURCE to this.

562# modifications, as well as for permanent customizations a user might
563# desire. Obviously, there can be no official support for arbitrarily
564# patched ebuilds. So whenever a build log in a bug report mentions that

572# level. The first call is the time when the patches will be

1026# basically look for the first lseek command (we do the strings/grep because
1027# sometimes the function call is _llseek or something) and steal the 2nd
1028# parameter. here is an example:
1029# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1030# lseek
1031# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
