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!

223# Often times code will want to enable a shell option to change code behavior.
224# Since changing shell options can easily break other pieces of code (which

226# options onto a stack and (2) pass the specified arguments to set.

356# epatch is designed to greatly simplify the application of patches. It can
357# process patch files directly, or directories of patches. The patches may be
358# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
359# the -p option as epatch will automatically attempt -p0 to -p4 until things
360# apply successfully.
195# 361#
196# It should work with .bz2, .gz, .zip and plain text patches. 362# If you do not specify any patches/dirs, then epatch will default to the
197# Currently all patches should be the same format. 363# directory specified by EPATCH_SOURCE.
198# 364#
199# You do not have to specify '-p' option to patch, as it will 365# 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. 366# for this specific invocation. As soon as an arg w/out a dash is found, then
367# arg processing stops.
201# 368#
202# Above EPATCH_* variables can be used to control various defaults, 369# 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 370# @CODE
204# them for. 371# 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.${EPATCH_SUFFIX} 372# ??_${ARCH}_foo.${EPATCH_SUFFIX}
373# else
374# *.${EPATCH_SUFFIX}
375# @CODE
376# The leading ?? are typically numbers used to force consistent patch ordering.
377# The arch field is used to apply patches only for the host architecture with
378# the special value of "all" means apply for everyone. Note that using values
379# other than "all" is highly discouraged -- you should apply patches all the
380# time and let architecture details be detected at configure/compile time.
211# 381#
212# For example: 382# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
383# for patches to apply.
213# 384#
214# 01_all_misc-fix.patch.bz2 385# 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.

670# of these three directories to exist will be the one to use, ignoring
671# any more general directories which might exist as well. They must end
672# in ".patch" to be applied.
673#
674# User patches are intended for quick testing of patches without ebuild
675# modifications, as well as for permanent customizations a user might
676# desire. Obviously, there can be no official support for arbitrarily
677# patched ebuilds. So whenever a build log in a bug report mentions that
678# user patches were applied, the user should be asked to reproduce the

685# level. The first call is the time when the patches will be

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
