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

111# This function is for bulk patching, or in theory for just one 270# @FUNCTION: epatch
112# 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.
113# 278#
114# 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
115# Currently all patches should be the same format. 280# directory specified by EPATCH_SOURCE.
116# 281#
117# 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
118# 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.
119# 285#
120# Above EPATCH_* variables can be used to control various defaults, 286# When processing directories, epatch will apply all patches that match:
121# bug they should be left as is to ensure an ebuild can rely on 287# @CODE
122# them for. 288# if ${EPATCH_FORCE} != "yes"
123#
124# Patches are applied in current directory.
125#
126# Bulk Patches should preferibly have the form of:
127#
128# ??_${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.
129# 298#
130# For example: 299# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
300# for patches to apply.
131# 301#
132# 01_all_misc-fix.patch.bz2 302# Refer to the other EPATCH_xxx variables for more customization of behavior.
133# 02_sparc_another-fix.patch.bz2
134#
135# This ensures that there are a set order, and you can have ARCH
136# specific patches.
137#
138# If you however give an argument to epatch(), it will treat it as a
139# single patch that need to be applied if its a file. If on the other
140# hand its a directory, it will set EPATCH_SOURCE to this.

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

1013# the size of the off_t type (in bytes) on the machine that built the pdv
1014# archive. one way to determine this is by running the following commands:
1015# strings <pdv archive> | grep lseek
1016# strace -elseek <pdv archive>
1017# basically look for the first lseek command (we do the strings/grep because
1018# sometimes the function call is _llseek or something) and steal the 2nd
1019# parameter. here is an example:
1020# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1021# lseek
1022# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1023# lseek(3, -4, SEEK_END) = 2981250
