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!

193# This function is for bulk patching, or in theory for just one 282# @FUNCTION: epatch
194# or two patches. 283# @USAGE: [options] [patches] [dirs of patches]
284# @DESCRIPTION:
285# epatch is designed to greatly simplify the application of patches. It can
286# process patch files directly, or directories of patches. The patches may be
287# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
288# the -p option as epatch will automatically attempt -p0 to -p5 until things
289# apply successfully.
195# 290#
196# It should work with .bz2, .gz, .zip and plain text patches. 291# If you do not specify any patches/dirs, then epatch will default to the
197# Currently all patches should be the same format. 292# directory specified by EPATCH_SOURCE.
198# 293#
199# You do not have to specify '-p' option to patch, as it will 294# Any options specified that start with a dash will be passed down to patch
200# try with -p0 to -p5 until it succeed, or fail at -p5. 295# for this specific invocation. As soon as an arg w/out a dash is found, then
296# arg processing stops.
201# 297#
202# Above EPATCH_* variables can be used to control various defaults, 298# When processing directories, epatch will apply all patches that match:
203# bug they should be left as is to ensure an ebuild can rely on 299# @CODE
204# them for. 300# if ${EPATCH_FORCE} != "yes"
205#
206# Patches are applied in current directory.
207#
208# Bulk Patches should preferibly have the form of:
209#
210# ??_${ARCH}_foo.${EPATCH_SUFFIX} 301# ??_${ARCH}_foo.${EPATCH_SUFFIX}
302# else
303# *.${EPATCH_SUFFIX}
304# @CODE
305# The leading ?? are typically numbers used to force consistent patch ordering.
306# The arch field is used to apply patches only for the host architecture with
307# the special value of "all" means apply for everyone. Note that using values
308# other than "all" is highly discouraged -- you should apply patches all the
309# time and let architecture details be detected at configure/compile time.
211# 310#
212# For example: 311# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
312# for patches to apply.
213# 313#
214# 01_all_misc-fix.patch.bz2 314# Refer to the other EPATCH_xxx variables for more customization of behavior.
215# 02_sparc_another-fix.patch.bz2
216#
217# This ensures that there are a set order, and you can have ARCH
218# specific patches.
219#
220# If you however give an argument to epatch(), it will treat it as a
221# single patch that need to be applied if its a file. If on the other
222# hand its a directory, it will set EPATCH_SOURCE to this.

589# of these three directories to exist will be the one to use, ignoring
590# any more general directories which might exist as well. They must end
591# in ".patch" to be applied.
592#
593# User patches are intended for quick testing of patches without ebuild
594# modifications, as well as for permanent customizations a user might
595# desire. Obviously, there can be no official support for arbitrarily
596# patched ebuilds. So whenever a build log in a bug report mentions that
597# user patches were applied, the user should be asked to reproduce the
598# problem without these.
599#
600# Not all ebuilds do call this function, so placing patches in the
601# stated directory might or might not work, depending on the package and
602# the eclasses it inherits and uses. It is safe to call the function
603# repeatedly, so it is always possible to add a call at the ebuild
604# level. The first call is the time when the patches will be
605# applied.
606#
607# Ideally, this function should be called after gentoo-specific patches
608# have been applied, so that their code can be modified as well, but

1006# strings <pdv archive> | grep lseek
1007# strace -elseek <pdv archive>
1008# basically look for the first lseek command (we do the strings/grep because
1009# sometimes the function call is _llseek or something) and steal the 2nd
1010# parameter. here is an example:
1011# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1012# lseek
1013# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1014# lseek(3, -4, SEEK_END) = 2981250
