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!

79# options onto a stack and (2) pass the specified arguments to set.
80#
81# A common example is to disable shell globbing so that special meaning/care
82# may be used with variables/arguments to custom functions. That would be:
83# @CODE
84# eshopts_push -o noglob

105# This function is for bulk patching, or in theory for just one 153# @FUNCTION: epatch
106# or two patches. 154# @USAGE: [patches] [dirs of patches]
155# @DESCRIPTION:
156# epatch is designed to greatly simplify the application of patches. It can
157# process patch files directly, or directories of patches. The patches may be
158# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
159# the -p option as epatch will automatically attempt -p0 to -p5 until things
160# apply successfully.
107# 161#
108# It should work with .bz2, .gz, .zip and plain text patches. 162# If you do not specify any options, then epatch will default to the directory
109# Currently all patches should be the same format. 163# specified by EPATCH_SOURCE.
110# 164#
111# You do not have to specify '-p' option to patch, as it will 165# When processing directories, epatch will apply all patches that match:
112# try with -p0 to -p5 until it succeed, or fail at -p5. 166# @CODE
113# 167# ${EPATCH_FORCE} == "yes"
114# Above EPATCH_* variables can be used to control various defaults,
115# bug they should be left as is to ensure an ebuild can rely on
116# them for.
117#
118# Patches are applied in current directory.
119#
120# Bulk Patches should preferibly have the form of:
121#
122# ??_${ARCH}_foo.${EPATCH_SUFFIX} 168# ??_${ARCH}_foo.${EPATCH_SUFFIX}
169# else
170# *.${EPATCH_SUFFIX}
171# @CODE
172# The leading ?? are typically numbers used to force consistent patch ordering.
173# The arch field is used to apply patches only for the host architecture with
174# the special value of "all" means apply for everyone. Note that using values
175# other than "all" is highly discouraged -- you should apply patches all the
176# time and let architecture details be detected at configure/compile time.
123# 177#
124# For example: 178# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
179# for patches to apply.
125# 180#
126# 01_all_misc-fix.patch.bz2 181# Refer to the other EPATCH_xxx variables for more customization of behavior.
127# 02_sparc_another-fix.patch.bz2
128#
129# This ensures that there are a set order, and you can have ARCH
130# specific patches.
131#
132# If you however give an argument to epatch(), it will treat it as a
133# single patch that need to be applied if its a file. If on the other
134# hand its a directory, it will set EPATCH_SOURCE to this.

1170# You have to specify the off_t size ... I have no idea how to extract that
1171# information out of the binary executable myself. Basically you pass in
1172# the size of the off_t type (in bytes) on the machine that built the pdv
1173# archive.
1174#
1175# One way to determine this is by running the following commands:
1176#
1177# @CODE
1178# strings <pdv archive> | grep lseek
1179# strace -elseek <pdv archive>
1180# @CODE
1181#
1182# Basically look for the first lseek command (we do the strings/grep because
1183# sometimes the function call is _llseek or something) and steal the 2nd
1184# parameter. Here is an example:
1185#
1186# @CODE
1187# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1188# lseek
1189# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1190# lseek(3, -4, SEEK_END) = 2981250
1191# @CODE
1192#
1193# Thus we would pass in the value of '4' as the second parameter.

1747# A temporary hack until portage properly supports DEPENDing on USE
1748# flags being enabled in packages. This will check to see if the specified
1749# DEPEND atom was built with the specified list of USE flags. The
1750# --missing option controls the behavior if called on a package that does
1751# not actually support the defined USE flags (aka listed in IUSE).
1752# The default is to abort (call die). The -a and -o flags control
1753# the requirements of the USE flags. They correspond to "and" and "or"
1754# logic. So the -a flag means all listed USE flags must be enabled
1755# while the -o flag means at least one of the listed IUSE flags must be
1756# enabled. The --hidden option is really for internal use only as it
1757# means the USE flag we're checking is hidden expanded, so it won't be found
1758# in IUSE like normal USE flags.
