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.
26#
27# To use, simply call:
28#
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 [[ $1 == -[su] ]] ; then
126 __ESHOPTS_SAVE__[$i]=$(shopt -p)

105# This function is for bulk patching, or in theory for just one 191# @FUNCTION: epatch
106# 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.
107# 199#
108# 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
109# Currently all patches should be the same format. 201# specified by EPATCH_SOURCE.
110# 202#
111# You do not have to specify '-p' option to patch, as it will 203# When processing directories, epatch will apply all patches that match:
112# try with -p0 to -p5 until it succeed, or fail at -p5. 204# @CODE
113# 205# ${EPATCH_FORCE} == "yes"
114# Above EPATCH_* variables can be used to control various defaults,
115# bug they should be left as is to ensure an ebuild can rely on
116# them for.
117#
118# Patches are applied in current directory.
119#
120# Bulk Patches should preferibly have the form of:
121#
122# ??_${ARCH}_foo.${EPATCH_SUFFIX} 206# ??_${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.
123# 215#
124# For example: 216# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
217# for patches to apply.
125# 218#
126# 01_all_misc-fix.patch.bz2 219# 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.

714# new convenience patch wrapper function to eventually replace epatch(),
715# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and
716# /usr/bin/patch
717# Features:
718# - bulk patch handling similar to epatch()'s
719# - automatic patch level detection like epatch()'s
720# - automatic patch uncompression like epatch()'s
721# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
722# manually instead
723# - once I decide it's production-ready, it'll be called from base_src_unpack
724# to handle $PATCHES to avoid defining src_unpack just to use xpatch
725
726# accepts zero or more parameters specifying patchfiles and/or patchdirs
727
728# known issues:
729# - only supports unified style patches (does anyone _really_ use anything
730# else?)
731# - because it doesn't use --dry-run there is a risk of it failing
732# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
733# any of the backup heuristics that patch employs to discover a filename.
734# however, this isn't dangerous because if it works for the developer who's
735# writing the ebuild, it'll always work for the users, and if it doesn't,
736# then we'll fix it :-)

1224# the middle of the archive. Valve seems to use it a lot ... too bad
1225# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1226#
1227# You have to specify the off_t size ... I have no idea how to extract that
1228# information out of the binary executable myself. Basically you pass in
1229# the size of the off_t type (in bytes) on the machine that built the pdv

1231#
1232# One way to determine this is by running the following commands:

1235# strings <pdv archive> | grep lseek
1236# strace -elseek <pdv archive>
1237# @CODE

1239# Basically look for the first lseek command (we do the strings/grep because
1240# sometimes the function call is _llseek or something) and steal the 2nd
1241# parameter. Here is an example:
1242#
1243# @CODE
1244# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1245# lseek
1246# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1247# lseek(3, -4, SEEK_END) = 2981250
1248# @CODE
