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
166# eshopts_pop

135# This function is for bulk patching, or in theory for just one 265# @FUNCTION: epatch
136# 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.
137# 273#
138# 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
139# Currently all patches should be the same format. 275# directory specified by EPATCH_SOURCE.
140# 276#
141# 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
142# 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.
143# 280#
144# Above EPATCH_* variables can be used to control various defaults, 281# When processing directories, epatch will apply all patches that match:
145# bug they should be left as is to ensure an ebuild can rely on 282# @CODE
146# them for. 283# if ${EPATCH_FORCE} != "yes"
147#
148# Patches are applied in current directory.
149#
150# Bulk Patches should preferibly have the form of:
151#
152# ??_${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.
153# 293#
154# For example: 294# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
295# for patches to apply.
155# 296#
156# 01_all_misc-fix.patch.bz2 297# Refer to the other EPATCH_xxx variables for more customization of behavior.
157# 02_sparc_another-fix.patch.bz2
158#
159# This ensures that there are a set order, and you can have ARCH
160# specific patches.
161#
162# If you however give an argument to epatch(), it will treat it as a
163# single patch that need to be applied if its a file. If on the other
164# hand its a directory, it will set EPATCH_SOURCE to this.

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

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

1107# basically look for the first lseek command (we do the strings/grep because
1108# sometimes the function call is _llseek or something) and steal the 2nd
1109# parameter. here is an example:
1110# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1111# lseek
1112# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
