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.

89# @FUNCTION: eshopts_push
90# @USAGE: [options to `set` or `shopt`]
91# @DESCRIPTION:
92# Often times code will want to enable a shell option to change code behavior.
93# Since changing shell options can easily break other pieces of code (which
94# assume the default state), eshopts_push is used to (1) push the current shell
95# options onto a stack and (2) pass the specified arguments to set.
96#
97# If the first argument is '-s' or '-u', we assume you want to call `shopt`
98# rather than `set` as there are some options only available via that.
99#
100# A common example is to disable shell globbing so that special meaning/care
101# may be used with variables/arguments to custom functions. That would be:
102# @CODE
103# eshopts_push -o noglob
104# for x in ${foo} ; do
105# if ...some check... ; then
106# eshopts_pop
85 return 0 107# return 0

111# @CODE

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

106# This function is for bulk patching, or in theory for just one 182# @FUNCTION: epatch
107# or two patches. 183# @USAGE: [patches] [dirs of patches]
184# @DESCRIPTION:
185# epatch is designed to greatly simplify the application of patches. It can
186# process patch files directly, or directories of patches. The patches may be
187# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
188# the -p option as epatch will automatically attempt -p0 to -p5 until things
189# apply successfully.
108# 190#
109# It should work with .bz2, .gz, .zip and plain text patches. 191# If you do not specify any options, then epatch will default to the directory
110# Currently all patches should be the same format. 192# specified by EPATCH_SOURCE.
111# 193#
112# You do not have to specify '-p' option to patch, as it will 194# When processing directories, epatch will apply all patches that match:
113# try with -p0 to -p5 until it succeed, or fail at -p5. 195# @CODE
114# 196# ${EPATCH_FORCE} == "yes"
115# Above EPATCH_* variables can be used to control various defaults,
116# bug they should be left as is to ensure an ebuild can rely on
117# them for.
118#
119# Patches are applied in current directory.
120#
121# Bulk Patches should preferibly have the form of:
122#
123# ??_${ARCH}_foo.${EPATCH_SUFFIX} 197# ??_${ARCH}_foo.${EPATCH_SUFFIX}
198# else
199# *.${EPATCH_SUFFIX}
200# @CODE
201# The leading ?? are typically numbers used to force consistent patch ordering.
202# The arch field is used to apply patches only for the host architecture with
203# the special value of "all" means apply for everyone. Note that using values
204# other than "all" is highly discouraged -- you should apply patches all the
205# time and let architecture details be detected at configure/compile time.
124# 206#
125# For example: 207# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
208# for patches to apply.
126# 209#
127# 01_all_misc-fix.patch.bz2 210# Refer to the other EPATCH_xxx variables for more customization of behavior.
128# 02_sparc_another-fix.patch.bz2
129#
130# This ensures that there are a set order, and you can have ARCH
131# specific patches.
132#
133# If you however give an argument to epatch(), it will treat it as a
134# single patch that need to be applied if its a file. If on the other
135# hand its a directory, it will set EPATCH_SOURCE to this.

759# new convenience patch wrapper function to eventually replace epatch(),
760# $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and
761# /usr/bin/patch
762# Features:
763# - bulk patch handling similar to epatch()'s
764# - automatic patch level detection like epatch()'s
765# - automatic patch uncompression like epatch()'s
766# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
767# manually instead
768# - once I decide it's production-ready, it'll be called from base_src_unpack
769# to handle $PATCHES to avoid defining src_unpack just to use xpatch
770
771# accepts zero or more parameters specifying patchfiles and/or patchdirs
772
773# known issues:
774# - only supports unified style patches (does anyone _really_ use anything
775# else?)
776# - because it doesn't use --dry-run there is a risk of it failing
777# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
778# any of the backup heuristics that patch employs to discover a filename.
779# however, this isn't dangerous because if it works for the developer who's
780# writing the ebuild, it'll always work for the users, and if it doesn't,
781# then we'll fix it :-)

1196# They're self-unpacking programs with the binary package stuffed in
1197# the middle of the archive. Valve seems to use it a lot ... too bad
1198# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1199#
1200# You have to specify the off_t size ... I have no idea how to extract that
1201# information out of the binary executable myself. Basically you pass in
1202# the size of the off_t type (in bytes) on the machine that built the pdv
1203# archive.
1204#
1205# One way to determine this is by running the following commands:
1206#
1207# @CODE
1208# strings <pdv archive> | grep lseek
1209# strace -elseek <pdv archive>
1210# @CODE
1211#
1212# Basically look for the first lseek command (we do the strings/grep because
1213# sometimes the function call is _llseek or something) and steal the 2nd
1214# parameter. Here is an example:
1215#
1216# @CODE
1217# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1218# lseek
1219# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1220# lseek(3, -4, SEEK_END) = 2981250
1221# @CODE
1222#
1223# Thus we would pass in the value of '4' as the second parameter.

1447# Aquire cd(s) for those lovely cd-based emerges. Yes, this violates
1448# the whole 'non-interactive' policy, but damnit I want CD support !
1449#
1450# With these cdrom functions we handle all the user interaction and
1451# standardize everything. All you have to do is call cdrom_get_cds()
1452# and when the function returns, you can assume that the cd has been
1453# found at CDROM_ROOT.
1454#
1455# The function will attempt to locate a cd based upon a file that is on
1456# the cd. The more files you give this function, the more cds
1457# the cdrom functions will handle.
1458#
1459# Normally the cdrom functions will refer to the cds as 'cd #1', 'cd #2',
1460# etc... If you want to give the cds better names, then just export
1461# the appropriate CDROM_NAME variable before calling cdrom_get_cds().
1462# Use CDROM_NAME for one cd, or CDROM_NAME_# for multiple cds. You can
1463# also use the CDROM_NAME_SET bash array.
