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!

20# libs in /lib. This is to fix linking problems when you have
21# the .so in /lib, and the .a in /usr/lib. What happens is that
22# in some cases when linking dynamic, the .a in /usr/lib is used
23# instead of the .so in /lib due to gcc/libtool tweaking ld's
24# library search path. This cause many builds to fail.
25# See bug #4411 for more info.

27# To use, simply call:

29# gen_usr_ldscript libfoo.so
30#
31# Note that you should in general use the unversioned name of
32# the library, as ldconfig should usually update it correctly
33# to point to the latest version of the library present.

98# @FUNCTION: eshopts_push
99# @USAGE: [options to `set` or `shopt`]
100# @DESCRIPTION:
101# Often times code will want to enable a shell option to change code behavior.
102# Since changing shell options can easily break other pieces of code (which
103# assume the default state), eshopts_push is used to (1) push the current shell
104# options onto a stack and (2) pass the specified arguments to set.
105#
106# If the first argument is '-s' or '-u', we assume you want to call `shopt`
107# rather than `set` as there are some options only available via that.
108#
109# A common example is to disable shell globbing so that special meaning/care
110# may be used with variables/arguments to custom functions. That would be:
111# @CODE
112# eshopts_push -o noglob
113# for x in ${foo} ; do
114# if ...some check... ; then
115# eshopts_pop
85 return 0 116# return 0

122 # have to assume __ESHOPTS_SAVE__ isn't screwed with
123 # as a `declare -a` here will reset its value
124 local i=${#__ESHOPTS_SAVE__[@]}
125 if [[ $1 == -[su] ]] ; then

100# This function is for bulk patching, or in theory for just one 191# @FUNCTION: epatch
101# or two patches. 192# @USAGE: [patches] [dirs of patches]
193# @DESCRIPTION:
194# epatch is designed to greatly simplify the application of patches. It can
195# process patch files directly, or directories of patches. The patches may be
196# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
197# the -p option as epatch will automatically attempt -p0 to -p5 until things
198# apply successfully.
102# 199#
103# It should work with .bz2, .gz, .zip and plain text patches. 200# If you do not specify any options, then epatch will default to the directory
104# Currently all patches should be the same format. 201# specified by EPATCH_SOURCE.
105# 202#
106# You do not have to specify '-p' option to patch, as it will 203# When processing directories, epatch will apply all patches that match:
107# try with -p0 to -p5 until it succeed, or fail at -p5. 204# @CODE
108# 205# ${EPATCH_FORCE} == "yes"
109# Above EPATCH_* variables can be used to control various defaults,
110# bug they should be left as is to ensure an ebuild can rely on
111# them for.
112#
113# Patches are applied in current directory.
114#
115# Bulk Patches should preferibly have the form of:
116#
117# ??_${ARCH}_foo.${EPATCH_SUFFIX} 206# ??_${ARCH}_foo.${EPATCH_SUFFIX}
207# else
208# *.${EPATCH_SUFFIX}
209# @CODE
210# The leading ?? are typically numbers used to force consistent patch ordering.
211# The arch field is used to apply patches only for the host architecture with
212# the special value of "all" means apply for everyone. Note that using values
213# other than "all" is highly discouraged -- you should apply patches all the
214# time and let architecture details be detected at configure/compile time.
118# 215#
119# For example: 216# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
217# for patches to apply.
120# 218#
121# 01_all_misc-fix.patch.bz2 219# Refer to the other EPATCH_xxx variables for more customization of behavior.
122# 02_sparc_another-fix.patch.bz2
123#
124# This ensures that there are a set order, and you can have ARCH
125# specific patches.
126#
127# If you however give an argument to epatch(), it will treat it as a
128# single patch that need to be applied if its a file. If on the other
129# hand its a directory, it will set EPATCH_SOURCE to this.

1225# the middle of the archive. Valve seems to use it a lot ... too bad
1226# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1227#
1228# You have to specify the off_t size ... I have no idea how to extract that

1230# the size of the off_t type (in bytes) on the machine that built the pdv

1233# One way to determine this is by running the following commands:

1236# strings <pdv archive> | grep lseek
1237# strace -elseek <pdv archive>
1238# @CODE

1241# sometimes the function call is _llseek or something) and steal the 2nd
1242# parameter. Here is an example:
1243#
1244# @CODE
1245# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1246# lseek
1247# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1248# lseek(3, -4, SEEK_END) = 2981250
1249# @CODE

1808# A temporary hack until portage properly supports DEPENDing on USE

1813# The default is to abort (call die). The -a and -o flags control
1814# the requirements of the USE flags. They correspond to "and" and "or"
1815# logic. So the -a flag means all listed USE flags must be enabled
1816# while the -o flag means at least one of the listed IUSE flags must be
1817# enabled. The --hidden option is really for internal use only as it
1818# means the USE flag we're checking is hidden expanded, so it won't be found

1946# @FUNCTION: prepalldocs
1947# @USAGE:
1948# @DESCRIPTION:
1949# Compress files in /usr/share/doc which are not already
1950# compressed, excluding /usr/share/doc/${PF}/html.
1951# Uses the ecompressdir to do the compression.
1952# 2009-02-18 by betelgeuse:
1953# Commented because ecompressdir is even more internal to
1954# Portage than prepalldocs (it's not even mentioned in man 5
1955# ebuild). Please submit a better version for review to gentoo-dev
1956# if you want prepalldocs here.
