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!

46# This function generate linker scripts in /usr/lib for dynamic 57else
47# libs in /lib. This is to fix linking problems when you have
48# the .so in /lib, and the .a in /usr/lib. What happens is that
49# in some cases when linking dynamic, the .a in /usr/lib is used
50# instead of the .so in /lib due to gcc/libtool tweaking ld's
51# library search path. This cause many builds to fail.
52# See bug #4411 for more info.

55#
56# gen_usr_ldscript libfoo.so
57#
58# Note that you should in general use the unversioned name of
59# the library, as ldconfig should usually update it correctly

151# @FUNCTION: eshopts_push
152# @USAGE: [options to `set` or `shopt`]
153# @DESCRIPTION:
154# Often times code will want to enable a shell option to change code behavior.
155# Since changing shell options can easily break other pieces of code (which
156# assume the default state), eshopts_push is used to (1) push the current shell
157# options onto a stack and (2) pass the specified arguments to set.
158#
159# If the first argument is '-s' or '-u', we assume you want to call `shopt`
160# rather than `set` as there are some options only available via that.
161#
162# A common example is to disable shell globbing so that special meaning/care
163# may be used with variables/arguments to custom functions. That would be:
164# @CODE
165# eshopts_push -s noglob
166# for x in ${foo} ; do
167# if ...some check... ; then
168# eshopts_pop

136 257
137# This function is for bulk patching, or in theory for just one 258# @FUNCTION: epatch
138# or two patches. 259# @USAGE: [patches] [dirs of patches]
260# @DESCRIPTION:
261# epatch is designed to greatly simplify the application of patches. It can
262# process patch files directly, or directories of patches. The patches may be
263# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
264# the -p option as epatch will automatically attempt -p0 to -p5 until things
265# apply successfully.
139# 266#
140# It should work with .bz2, .gz, .zip and plain text patches. 267# If you do not specify any options, then epatch will default to the directory
141# Currently all patches should be the same format. 268# specified by EPATCH_SOURCE.
142# 269#
143# You do not have to specify '-p' option to patch, as it will 270# When processing directories, epatch will apply all patches that match:
144# try with -p0 to -p5 until it succeed, or fail at -p5. 271# @CODE
145# 272# if ${EPATCH_FORCE} != "yes"
146# Above EPATCH_* variables can be used to control various defaults,
147# bug they should be left as is to ensure an ebuild can rely on
148# them for.
149#
150# Patches are applied in current directory.
151#
152# Bulk Patches should preferibly have the form of:
153#
154# ??_${ARCH}_foo.${EPATCH_SUFFIX} 273# ??_${ARCH}_foo.${EPATCH_SUFFIX}
274# else
275# *.${EPATCH_SUFFIX}
276# @CODE
277# The leading ?? are typically numbers used to force consistent patch ordering.
278# The arch field is used to apply patches only for the host architecture with
279# the special value of "all" means apply for everyone. Note that using values
280# other than "all" is highly discouraged -- you should apply patches all the
281# time and let architecture details be detected at configure/compile time.
155# 282#
156# For example: 283# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
284# for patches to apply.
157# 285#
158# 01_all_misc-fix.patch.bz2 286# Refer to the other EPATCH_xxx variables for more customization of behavior.
159# 02_sparc_another-fix.patch.bz2
160#
161# This ensures that there are a set order, and you can have ARCH
162# specific patches.
163#
164# If you however give an argument to epatch(), it will treat it as a
165# single patch that need to be applied if its a file. If on the other
166# hand its a directory, it will set EPATCH_SOURCE to this.

515# Applies user-provided patches to the source tree. The patches are
516# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
517# of these three directories to exist will be the one to use, ignoring
518# any more general directories which might exist as well.
519#
520# User patches are intended for quick testing of patches without ebuild
521# modifications, as well as for permanent customizations a user might
522# desire. Obviously, there can be no official support for arbitrarily
523# patched ebuilds. So whenever a build log in a bug report mentions that
524# user patches were applied, the user should be asked to reproduce the
525# problem without these.
526#
527# Not all ebuilds do call this function, so placing patches in the
528# stated directory might or might not work, depending on the package and
529# the eclasses it inherits and uses. It is safe to call the function
530# repeatedly, so it is always possible to add a call at the ebuild
531# level. The first call is the time when the patches will be
532# applied.
533#
534# Ideally, this function should be called after gentoo-specific patches
535# have been applied, so that their code can be modified as well, but
536# before calls to e.g. eautoreconf, as the user patches might affect
537# autotool input files as well.

990# the middle of the archive. Valve seems to use it a lot ... too bad
991# it seems to like to segfault a lot :(. So lets take it apart ourselves.
992#
993# Usage: unpack_pdv [file to unpack] [size of off_t]
994# - you have to specify the off_t size ... i have no idea how to extract that
995# information out of the binary executable myself. basically you pass in
996# the size of the off_t type (in bytes) on the machine that built the pdv
997# archive. one way to determine this is by running the following commands:
998# strings <pdv archive> | grep lseek
999# strace -elseek <pdv archive>
1000# basically look for the first lseek command (we do the strings/grep because
1001# sometimes the function call is _llseek or something) and steal the 2nd
1002# parameter. here is an example:
1003# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1004# lseek
1005# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1006# lseek(3, -4, SEEK_END) = 2981250
1007# thus we would pass in the value of '4' as the second parameter.
