The removal of the .git dir before creating the tarball is not anymore
just an optimization. It is necessary to make the tarball reproducible.
Also, without the removal, large tarballs (gigabytes) would be created
for some linux trees.

Unextected error in the br2-external script are properly caught, but
they are not reported properly, and we end up in either of two
situations:
- the .br2-external.mk file is not generated, in which case make will
try to find a rule to generate it (because the 'include' directive
tries to generate missing files);
- the .br-external.mk file is generated but does not contain the error
variable, and thus the build might not get interrupted.
We fix that by using a trap on the pseudo ERR signal, to emit the error
variable on unexpected errors.

In commit 2f6c5e513c
("support/check-bin-arch: fix for filenames with spaces"), Yann
adjuste the check-bin-arch script to properly handle filenames with
spaces.
However, he also did a subtle change of the regexp that extracts the
path of the files. It was:
"/^${package},(.+)$/!d; s//\1/;"
and Yann changed it to:
"/^${package},\.(.+)$/!d; s//\1/;"
So the file paths used to start with a dot (like "./usr/share/foo"),
and now they no longer start with a dot (like "/usr/share/foo"). While
this modification is good and makes sense, the match for
/lib/firmware/ was not adjusted accordingly, and the follow-up patch
also ignoring /usr/share was not adjusted as well.
This commit fixes those /lib/firmware/ and /usr/share/ special cases,
which will fix:

On most distros, the tar format defaults to GNU. However, at build time
the default format may be changed to posix. Also, future versions of
tar will default to posix.
Since we want the tarballs created by the git download method to be
reproducible (so their hash can be checked), we should explicitly
specify the format. Since existing tarballs on sources.buildroot.org
use the GNU format, and also the existing hashes in the *.hash files
are based on GNU format tarballs, we use the GNU format.
In addition, the Posix format encodes atime and ctime as well as mtime,
but tar offers no option like --mtime to override them. In the GNU
format, atime and ctime are only encoded if the --incremental option is
given.

As shown recently by the firejail example, it is easy to miss that a
package builds and installs binaries without actually cross-compiling
them: they are built for the host architecture instead of the target
architecture.
This commit adds a small helper script, check-bin-arch, called as a
GLOBAL_INSTRUMENTATION_HOOKS at the end of the target installation of
each package, to verify that the files installed by this package have
been built for the correct architecture.
Being called as a GLOBAL_INSTRUMENTATION_HOOKS allows the build to error
out right after the installation of the faulty package, and therefore
get autobuilder error detection properly assigned to this specific
package.
Example output with the firejail package enabled, when building for an
ARM target:
ERROR: architecture for ./usr/lib/firejail/libconnect.so is Advanced Micro Devices X86-64, should be ARM
ERROR: architecture for ./usr/bin/firejail is Advanced Micro Devices X86-64, should be ARM

Currently, we tell cmake where to look for our own custom platform
description by passing the path to the moduls directory on the command
line.
However, this causes two different problems.
First, some packages simply set CMAKE_MODULE_PATH in their
CMakeList.txt, thus overriding our own path, and then our platform
description is not found.
Second, cmake may internally call sub-cmake (e.g. in the try_compile
macro), but the CMAKE_MODULE_PATH is not automatically passed down in
this case.
For the first problem, we could hunt down and fix all offenders, but
this is an endless endeavour, especially since packagers are told to do
so on the cmake wiki [0]:
CMAKE_MODULE_PATH
tell CMake to search first in directories listed in
CMAKE_MODULE_PATH when you use FIND_PACKAGE() or INCLUDE()
SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/MyCMakeScripts)
FIND_PACKAGE(HelloWorld)
The second problem could be solved by passing yet another variable on
the command line, that tells cmake to explicitly pass arbitrary
variables down to sub-cmake calls:
-DCMAKE_TRY_COMPILE_PLATFORM_VARIABLES=CMAKE_MODULE_PATH
However, this only covers the case of try_compile. Even though no other
case is known yet, we'd still risk missing locations where we would need
to propagate CMAKE_MODULE_PATH, even some where we'd have no solution
like for try_compile.
Instead, ngladitz on IRC suggested that CMAKE_MODULE_PATH be set
directly from the toolchain file.
And indeed this fixes both problems explained above.
So be it.

The handling of RPATH in cmake-3.7 has changed drastically, causing a
slew of build failures dues to libraries from the host being pulled in:
- domoticz : http://autobuild.buildroot.org/results/fd0/fd0ba54c7abf973691b39a0ca1bb4e07d749593a/
- freerdp : http://autobuild.buildroot.org/results/5d4/5d429d0e288754a541ee5d8be515454c5fccd28b/
- libcec : http://autobuild.buildroot.org/results/3f3/3f3593bab7734dd274faf5b5690895e9424cbb89/
- and so on...
The bug was reported upstream [0], which dismissed it altogether [1] as
being expected behaviour, quoting:
I don't think there is anything wrong with that change on its own.
It merely exposed some existing behavior in a new case.
Instead, upstream suggested in that same message that a platform
definition be used instead, quoting:
If a toolchain file specifies CMAKE_SYSTEM_NAME such that a custom
`Platform/MySystem.cmake` file is loaded then the latter can set
them as needed for the target platform.
So here we are doing so:
- we add a new platfom definitions that inherits from the Linux one,
then overrides the problematic settings;
- we change our toolchain file to use that platform instead;
- we tell cmake where to find additional modules, so that it can find
our custom platform file.
This has been tested to work in the following conditions:
- pre-installed host cmake, versions 3.5.1 (Ubuntu 16.04) and 3.7.2
(manually built)
- internal cmake, versions 3.6.3 (the current version as of this
patch) and 3.7.2 (with the followup patches).
Thanks to Jörg, Ben and Baruch for the help investigating the issue.
Special thanks to Jörg for handling the discussion with upstream and
pointing to the relevant messages! :-)

weigh in at about 170 MB with the total filesystem size reported as

It is a bit complex to understand the actual technical reason for this

Recently, the autoconf macros for libtool started using '/usr/bin/file'
to determine the type of library that is generated by the toolchain.
Packages that use this recent version of the libtool autoconf macros
will fail in a rather dramatic way when /usr/bin/file is not present
on the host: the package will still build but no shared library is
generated, which in turn may cause build failures in other packages
that link with it.
For example, libpng's configure determines that it is not possible to
build a shared library on MIPS64 because the expected output from 'file'
is not present. Therefore, only a static libpng.a is built. Later,
bandwithd links with -lpng but it doesn't use the pkg-config's
Private-Libs (because it's not linking statically) and it doesn't have
access to the NEEDED reference from the shared library. Therefore, it
doesn't link with zlib and fails with
pngrutil.c:(.text+0x55c): undefined reference to `inflate'
We cant use host-file because it is itself an autotools package and is
itself using libtool, so this would be a chicken-n-egg problem. Besides,
the libtool script really wants to call /usr/bin/file, so it would not
even find our host-file anyway.
So, just require that '/usr/bin/file' is present on the host.

Many (100+) packages supported by buildroot contain old configure
scripts (or build them from old versions of autotools) that are unable
to determine how to link shared libraries on powerpc64 and
powerpc64le. This causes that test to erroneously fail on toolchains
that are not "bi-endian" (which is the case for toolchains built by
buildroot), which causes configure to build static libraries instead
of dynamic ones. Although these builds succeed, they tend to cause
linker failures in binaries later linked against them.
Because affected configure files can be discovered automatically, this
patch introduces a hook (enabled only when building for powerpc64 and
powerpc64le) that uses a script to scan and fix each package.

Currently, there are two failure paths in the wrapper:
- if the tar fails, then the error is ignored because it is on the
left-hand-side of a pipe;
- if the find fails, then the error is ignored because it is a
process substitution (and there is a pipe, too).
While the former could be fixed with "set -o pipefail", the latter can
not be fixed thusly and we must use an intemediate file for it.
So, fix both issues by using intermediate files, both to generate the

From the build configuration, Buildroot defines and set some compiler
and linker flags that should be passed to any packages build-system.
For package using the cmake-package infrastructure, this is achieved
via the toolchainfile.cmake.
This change simplifies the way the toolchainfile.cmake file handles
these flags: it now just sets them, without any attempt to extend them
with those Buildroot defined.
This change still allows overriding these flags from the configure
command line.
So, now, when a CMake-based package needs to extend them, they should
be fully set from the package *.mk file. This behavior is consistent
with what is done for others package infrastructures.
This change should not pull any regression WRT the bug #7280 [1].
However, now, when someone uses the toolchainfile.cmake file outside of
Buildroot, he/she must overload all compiler/linker flags (including the
ones Buildroot sets since they no longer get automatically added).

When a build type is set, CMake does append some flags that can override
those set by Buildroot due to the gcc option parser (in which the last
argument controling an option wins).
Hereafter is a summary of the optimization and debug flags set by
Buildroot and appended by CMake.
* Flags set by Buildroot depending on the configuration:
BR2_ENABLE_DEBUG | Optim. level | Buildroot {C,CXX}FLAGS
=================+=====================+=======================
y | BR2_OPTIMIZE_S | -Os -gx
y | BR2_OPTIMIZE_G | -Og -gx
y | BR2_OPTIMIZE_{0..3} | -On -gx
n | BR2_OPTIMIZE_S | -Os
n | BR2_OPTIMIZE_G | -Og
n | BR2_OPTIMIZE_{0..3} | -On
* Default flags appended by CMake depending on the build type:
Build type | Flags | Effects on {C,CXX}FLAGS
===============+=================+===========================================
Debug | -g | Force -g, compatible with BR2_ENABLE_DEBUG
MinSizeRel | -Os -DNDEBUG | Set -Os, compatible with BR2_OPTIMIZE_S
Release | -O3 -DNDEBUG | Set -O3, closest to the others cases,
| | though the optimization level is forced.
RelWithDebInfo | -O2 -g -DNDEBUG | Force -g and set -O2, not friendly with BR
To avoid the CMake flags take precedence over the Buildroot ones, this
change sets in toolchainfile.cmake the per-config compiler flags CMake
can append depending on the build type Buildroot defined.
So, CMake does not mess up with the compilation flags Buildroot sets.
It is still possible to override these per-config flags on the cmake
command line.
Note:
If a CMake-based project forces the compiler and/or linker flag
definitions (the default ones or the per-config ones - e.g.
CMAKE_C_FLAGS/CMAKE_C_FLAGS_{DEBUG,RELEASE}), there is not much
Buildroot can do about it.
So, the flags will be overwritten anyway in these cases.

Now that we support multiple br2-external trees, BR2_EXTERNAL is no
longer exported in the environment.
This means that post-build scripts in a br2-external tree can no longer
find their own files (well, they could re-invent the path by stripping
their known-relative path, but that'd be ugly, especially since we can
very well provide it).
Export the path for each br2-external trees as environment variables.
Do so for the description as well, as a courtesy.
Also, re-order variable definitions to be more logical: first, purely
internal variables, then exported variables.

Currently, it is not possible for a br2-external tree to override a
defconfig bundled in Buildroot, nor is it possible to override one from
a previous br2-external tree in the stack.
However, it is interesting that a latter br2-external tree be able to
override a defconfig:
- the ones bundled in Buildroot are minimalist, and almost always
build a toolchain, so a br2-external tree may want to provide a
"better" defconfig (better, in the sense "suited for the project");
- similarly for a defconfig from a previous br2-external tree.
But we can't do that, as the rules for the defconfigs are generated in
the order the br2-external trees are specified, all after the bundled
defconfigs. Those rule are patten-matching rules, which means that the
first one to match is used, and the following ones are ignored.
Add a new utility macro, 'reverse', inspired from GMSL, that does what
it says: reverse a list of words.
Use that macro to reverse the list of br2-external trees, so that the
latters win over the formers, and even over bundled ones.

Currently, we only support at most one br2-external tree. Being able
to use more than one br2-external tree can be very useful.
A use-case would be for having a br2-external to contain the basic
packages, basic board defconfigs and board files, provided by one team
responsible for the "board-bringup", while other teams consume that
br2-external as a base, and complements it each with their own set of
packages, defconfigs and extra board files.
Another use-case would be for third-parties to provide their own
Buildroot packaging in a br2-external tree, along-side the archives for
their stuff.
Finally, another use-case is to be able to add FLOSS packages in a
br2-external tree, and proprietary packages in another. This allows
to not touch the Buildroot tree at all, and still be able to get in
compliance by providing only that br2-external tree(s) that contains
FLOSS packages, leaving aside the br2-external tree(s) with the
proprietary bits.
What we do is to treat BR2_EXTERNAL as a colon-separated (space-
separated also work, and we use that internally) list of paths, on which
we iterate to construct:
- the list of all br2-external names, BR2_EXTERNAL_NAMES,
- the per-br2-external tree BR2_EXTERNAL_$(NAME) variables, which
point each to the actual location of the corresponding tree,
- the list of paths to all the external.mk files, BR2_EXTERNAL_MKS,
- the space-separated list of absolute paths to the external trees,
BR2_EXTERNAL_DIRS.
Once we have all those variables, we replace references to BR2_EXTERNAL
with either one of those.
This cascades into how we display the list of defconfigs, so that it is
easy to see what br2-external tree provides what defconfigs. As
suggested by Arnout, tweak the comment from "User-provided configs" to
"External configs", on the assumption that some br2-external trees could
be provided by vendors, so not necessarily user-provided. Ditto the menu
in Kconfig, changed from "User-provided options" to "External options".
Now, when more than one br2-external tree is used, each gets its own
sub-menu in the "User-provided options" menu. The sub-menu is labelled
with that br2-external tree's name and the sub-menu's first item is a
comment with the path to that br2-external tree.
If there's only one br2-external tree, then there is no sub-menu; there
is a single comment that contains the name and path to the br2-external
tree.

This unique NAME is used to construct a per br2-external tree variable,
BR2_EXTERNAL_$(NAME)_PATH, which contains the path to the br2-external
tree.
This variable is available both from Kconfig (set in the Kconfig
snippet) and from the .mk files.
Also, display the NAME and its path as a comment in the menuconfig.
This will ultimately allow us to support multiple br2-external trees at
once, with that NAME (and thus BR2_EXTERNAL_$(NAME)) uniquely defining
which br2-external tree is being used.
The obvious outcome is that BR2_EXTERNAL should now no longer be used to
refer to the files in the br2-external tree; that location is now known
from the BR2_EXTERNAL_$(NAME)_PATH variable instead. This means we no
longer need to expose, and must stop from from exposing BR2_EXTERNAL as
a Kconfig variable.
Finally, this also fixes a latent bug in the pkg-generic infra, where we
would so far always refer to BR2_EXTERNAL (even if not set) to filter
the names of packages (to decide whether they are a bootloader, a
toolchain or a simple package).
Note: since the variables in the Makefile and in Kconfig are named the
same, the one we computed early on in the Makefile will be overridden by
the one in .config when we have it. Thus, even though they are set to
the same raw value, the one from .config is quoted and, being included
later in the Makefile, will take precedence, so we just re-include the
generated Makefile fragment a third time before includeing the
br2-external's Makefiles. That's unfortunate, but there is no easy way
around that as we do want the two variables to be named the same in
Makefile and Kconfig (and we can't ask the user to un-quote that variable
himself either), hence this little dirty triple-inclusion trick.

Currently, we treat the case where we have no br2-external tree
(BR2_EXTERNAL is empty) differently from the case where we do have one
(BR2_EXTERNAL is not empty).
There is now no reason to treat those two cases differently:
- the kconfig snippet is always generated appropriately (i.e. it would
include the br2-external tree if set, or include nothing otherwise);
- we no longer have a dummy br-external tree either.
Also, the Makefile code to handle BR2_EXTERNAL is currently quite
readable if at least a little bit tricky.
However, when we're going to add support for using multiple br2-external
trees simultaneously, this code would need to get much, much more complex.
To keep the Makefile (rather) simple, offload all of the handling of
BR2_EXTERNAL to the recently added br2-external helper script.
However, because of Makefiles idiosyncracies, we can't use a rule to
generate that Makefile fragment.
Instead, we use $(shell ...) to call the helper script, and include the
fragment twice: once before the $(shell ...) so we can grab a previously
defined BR2_EXTERNAL value, a second time to use the one passed on the
command line, if any.
Furthermore, we can't error out (e.g. on non-existent br2-external tree)
directly from the fragment or we'd get that error on subsequent calls,
with no chance to override it even from command line.
Instead, we use a variable in which we store the error, set it to empty
before the second inclusion, so that only the one newly generated, if
any, is taken into account.
Since we know the script will always be called from Makefile context
first, we know validation will occur in Makefile context first. So we
can assume that, if there is an error, it will be detected in Makefile
context. Consequently, if the script is called to generate the kconfig
fragment, validation has already occured, and there should be no error.
So we change the error function to generate Makefile code, so that
errors are caught as explained above.
Lastly, when the value of BR2_EXTERNAL changes, we want to 'forget'
about the previous value of the BR2_EXTERNAL_MK variable, especially in
the case where BR2_EXTERNAL is now set to empty, so that we do not try
to include it later. That's why we first generate empty version of
BR2_EXTERNAL_MK, and then assign it the new value, if any.

Now that we generate a kconfig snippet, we can conditionally include the
BR2_EXTERNAL's Config.in only when BR2_EXTERNAL is supplied by the user,
which means our empty/dummy Config.in is no needed.
As for external.mk, we can also include it only when BR2_EXTERNAL is
supplied by the user, which means our empty/dummy external.mk is no
longer needed.
Ditch both of those files, and:
- only generate actual content in the Kconfig snippet when we actually
do have a BR2_EXTERNAL provided by the user (i.e. BR2_EXTERNAL is not
empty);
- add a variable that contains the path to the external.mk provided by
the user, or empty if none, and include the path set in that variable
(make can 'include' nothing without any problem! ;-) )

This script, and its companion library, is more-or-less Buildroot's
equivalent to the kernel get_maintainer.pl script: it allows to get the
list of developers to whom a set of patches should be sent to.
To do so, it first relies on a text file, named DEVELOPERS, at the root
of the Buildroot source tree (added in a followup commit) to list the
developers and the files they are interested in. The DEVELOPERS file's
format is simple:
N: Firstname Lastname <email>
F: path/to/file
F: path/to/another/file
This allows to associate developers with the files they are looking
after, be they related to a package, a defconfig, a filesystem image, a
package infrastructure, the documentation, or anything else.
When a directory is given, the tool assumes that the developer handles
all files and subdirectories in this directory. For example
"package/qt5/" can be used for the developers looking after all the Qt5
packages.
Conventional shell patterns can be used, so "package/python-*" can be
used for the developers who want to look after all packages matching
"python-*".
A few files are recognized specially:
- .mk files are parsed, and if they contain $(eval
$(<something>-package)), the developer is assumed to be looking after
the corresponding package. This way, autobuilder failures for this
package can be reported directly to this developer.
- arch/Config.in.<arch> files are recognized as "the developer is
looking after the <arch> architecture". In this case, get-developer
parses the arch/Config.in.<arch> to get the list of possible BR2_ARCH
values. This way, autobuilder failures for this package can be
reported directly to this developer.
- pkg/pkg-<infra>.mk are recognized as "the developer is looking after
the <infra> package infrastructure. In this case, any patch that adds
or touches a .mk file that uses this infrastructure will be sent to
this developer.

We currently have four lists of packages in the manual:
- the non-virtual target packages,
- the virtual target packages,
- the host packages,
- the deprecated features.
Those list take more than half of the manual. They do not serve much
purpose except to show off.
After the recent discussion on the list [0], remove them all.
We can now get rid of our biggish and complex generating script (and its
companion library kconfiglib).

Currently all cmake packages depend on host-cmake. Unfortunately
host-cmake takes a long time to configure and build: almost 7 minutes
on a dual-core i5 with SSD. The time does not change even with ccache
enabled.
Indeed, building host-cmake is avoidable if it is already installed on
the build host: CMake is supposed to be quite portable, and the only
patch in Buildroot for the CMake package seems to only affect
target-cmake.
Thus we automatically skip building host-cmake and use the one on the
system if:
- cmake is available on the system and
- it is recent enough.
First, we leverage the existing infrastructure in
support/dependencies/dependencies.mk to find out whether there's a
suitable cmake executable on the system. Its path can be passed in the
BR2_CMAKE environment variable, otherwise it defaults to "cmake". If
it is enabled, found and suitable then we set BR2_CMAKE_HOST_DEPENDENCY
to empty; otherwise we set BR2_CMAKE_HOST_DEPENDENCY to 'host-cmake' and
override BR2_CMAKE with "$(HOST_DIR)/usr/bin/cmake" to revert to using
our own cmake (the old behaviour).
Then in pkg-cmake.mk we replace the hard-coded dependency on host-cmake
to using the BR2_CMAKE_HOST_DEPENDENCY variable, and we use $(BR2_CMAKE)
instead of $(HOST_DIR)/usr/bin/cmake.
Unlike what we do for host-tar and host-xzcat, for host-cmake we do
not add host-cmake to DEPENDENCIES_HOST_PREREQ. If we did, host-cmake
would be a dependency for _any_ package when it's not installed on the
host, even when no cmake package is selected.
Cmake versions older than 3.0 are affected by the bug described and
fixed in Buildroot in ef2c1970e4 ("cmake: add patch to fix Qt mkspecs
detection"). The bug was fixed in upstream CMake in version 3.0 [0].
Amongst all the cmake packages currently in Buildroot, the currently
highest version mentioned in cmake_minimum_required() is 3.1 (grantlee
and opencv3).
Thus we use 3.1 as the lowest required cmake for now, until a package is
bumped, or a new package added, with a higher required version.

pkg-utils.mk contains various definitions that are used in the package
infrastructures and packages themselves.
However, those definitions can be useful in other parts of Buildroot,
and are already used in a few places that are not related to the package
infrastructure. Also, $(sep) will be needed early in the Makefile when
we eventually support multiple br2-external trees.
Since this file only contains definitions, we can include it anytime.
So, consider that file to no longer be specific to the package infras:
- move it to support and rename it,
- move a few similar definitions from the main Makefile to that file.

Some git repositories may be split into a master repository and
submodules. Up until now, we did not have support for submodules,
because we were using bare clones, in which it is not possible to
update the list of submodules.
Now that we are using plain clones with a working copy, we can retrieve
the submdoules.
Add an option to the git download helper to kick the update of
submodules, so that they are only fetched for those packages that
require them. Also document the existing -q option at the same time.
Submodules have a .git file at their root, which contains the path to
the real .git directory of the master repository. Since we remove it,
there is no point in keeping those .git files either.
Note: this is currently unused, but will be enabled with the follow-up
patch that adds the necessary parts in the pkg-generic and pkg-download
infrastructures.

We currently use git-archive to generate the tarball. This is all handy
and dandy, but git-archive does not support submodules. In the follow-up
patch, we're going to handle submodules, so we would not be able to use
git-archive.
Instead, we manually generate the archive:
- extract the tree to the requested cset,
- get the date of the commit to store in the archive,
- store only numeric owners,
- store owner and group as 0 (zero, although any arbitrary value would
have been fine, as long as it's a constant),
- sort the files to store in the archive.
We also get rid of the .git directory, because there is no reason to
keep it in the context of Buildroot. Some people would love to keep it
so as to speed up later downloads when updating a package, but that is
not really doable. For example:
- use current Buildroot
- it would need foo-12345, so do a clone and keep the .git in the
generated tarball
- update Buildroot
- it would need foo-98765
For that second clone, how could we know we would have to first extract
foo-12345 ? So, the .git in the archive is pretty much useless for
Buildroot.

Currently, we are using bare clones, so as to minimise the disk usage,
most notably for largeish repositories such as the one for the Linux
kernel, which can go beyond the 1GiB barrier.
However, this precludes updating (and thus using) the submodules, if
any, of the repositories, as a working copy is required to use
submodules (becaue we need to know the list of submodules, where to find
them, where to clone them, what cset to checkout, and all those is
dependent upon the checked out cset of the father repository).
Switch to using /plain/ clones with a working copy.
This means that the extra refs used by some forges (like pull-requests
for Github, or changes for gerrit...) are no longer fetched as part of
the clone, because git does not offer to do a mirror clone when there is
a working copy.
Instead, we have to fetch those special refs by hand. Since there is no
easy solution to know whether the cset the user asked for is such a
special ref or not, we just try to always fetch the cset requested by
the user; if this fails, we assume that this is not a special ref (most
probably, it is a sha1) and we defer the check to the archive creation,
which would fail if the requested cset is missing anyway.

Currently, the legal-info infra only saves the source archive of a
package. However, that's not enough as we may apply some patches on
packages sources.
We do suggest users to also redistribute the Buildroot sources as part
of their compliance distribution, so the patches bundled in Buildroot
would indeed be included in the compliance distribution.
However, that's still not enough, since we may download some patches, or
the user may use a global patch directory. Patches in there might not
end up in the compliance distribution, and there are risks of
non-conformity.
So, always include patches alongside the source archive.
To ensure reproducibility, we also generate a series file, so patches
can be re-applied in the correct order.
We get the list of patches to include from the list of patches that were
applied by the package infrastructure (via the apply-patches support
script). So, we need to get packages properly extracted and patched
before we can save their legal-info, not just in the case they define
_LICENSE_FILES.
Update the legal-info header accordingly.
Note: this means that, when a package is not patched and defines no
LICENSE_FILES, we will extract and patch it for nothing. There is no
easy way to know whether we have to patch a package or not. We can only
either duplicate the logic to detect patches (bad) or rely on the infra
actually patching the package. Also, a vast majority of packages are
either patched, or define _LICENSE_FILES, so it is best and easiest to
always extract and patch them prior to legal-info.

Patches we save can come from various locations:
- bundled with Buildroot
- downloaded
- from one or more global-patch-dir
It is possible that two patches lying into different locations have the
same basename, like so (first is bundled, second is from an hypothetical
global-patch-dir):
package/foo/0001-fix-Makefile.patch
/path/to/my/patches/foo/0001-fix-Makefile.patch
In that case, when running legal-info, we'd save only the second patch,
overwriting the first. That would be problematic, because:
- either the second patch depends on the first, and thus would no longer
apply (this is easy to detect, though),
- or the second patch does not depend on the first, and the compliance
delivery will not be complete (this is much harder to detect).
We fix that by checking that no two patches have the same same basename.
If we find that the basename of the patch to be applied collides with
that of a previously applied patch, we error out and report the duplicate.
The unfortunate side-effect is that existing setups will now break in
that situation, but that's a minor, corner-case issue that is easily
fixed.

Currently, each python package (be it the python interpreter package
itself or external python modules) is responsible for compiling its
.py into .pyc files. Unfortunately, this is not ideal as some packages
only install .py files without compiling them into .pyc files. In this
case, if the Buildroot configuration specifies to keep only the .pyc
files, the .py files are removed and lost.
To address this, this commit changes the logic by making the
compilation of .pyc files a global operation: the python interpreter
packages register a target finalize hook that is in charge of
compiling all installed .py files.
The *.pyc generation on a per package basis is disabled in the
python-package infrastructure by passing the "--no-compile" option to
setup.py.
The *.pyc generation for the Python interpreter internal modules is
disabled through --disable-pyc-build configure option.
A small helper script is used to perform the compilation, the purpose
of this script is to abort the compilation process if one of the .py
file cannot be compiled. It has been provided by Samuel Martin and
integrated into this commit.

When preparing the legal-info, the source archives are copied in the
legal-info/ output directory. When the archives are big, it can take
quite a bit of time and unnecessarily uses disk space. When the
legal-info output directory is on the same filesystem as the BR2_DL_DIR,
we can easily reduce copy time and disk usage by just using hardlins
instead of copying. However, the BR2_DL_DIR may be on a different
filesystem, so we must fallback to copying in this case
Introduce a helper script that copies a source file into a destination
directory, by first attempting to hard-link, and falling back to a
plain copy in case the hardlink fails.
In case the destination already exists, it is forcibly removed first, to
avoid clobering any existing target file (and especially any hardlink to
it), since cp -f does not remove the destination file, but clobbers it.
In some situations, it will be necessary that the destination file is
named differently than the source, so if a third argument is specified,
it is treated as the basename of the destination file.

Currently, if there is a circular dependency in the packages, the
graph-depends script just errors out with a Python RuntimeError which is
not caught, resulting in a very-long backtrace which does not provide
any hint as what the real issue is (even if "RuntimeError: maximum
recursion depth exceeded" is a pretty good hint at it).
We fix that by recursing the dependency chain of each package, until we
either end up with a package with no dependency, or with a package
already seen along the current dependency chain.
We need to introduce a new function, check_circular_deps(), because we
can't re-use the existing ones:
- remove_mandatory_deps() does not iterate,
- remove_transitive_deps() does iterate, but we do not call it for the
top-level package if it is not 'all'
- it does not make sense to use those functions anyway, as they were
not designed to _check_ but to _act_ on the dependency chain.
Since we've had time-related issues in the past, we do not want to
introduce yet another time-hog, so here are timings with the circular
dependency check:

Currently, graph-depends outputs the dotfile program to stdout, and uses
stderr to trace the dependencies it is currently looking for.
Redirection was done because the output was directly piped into the dot
program to generate the final PDF/SVG/... dependency graph, but that
meant that an error in the graph-depends script was never caught
(because shell pipes only return the final command exit status, and an
empty dot program is perfectly valid so dot would not complain).
Add an option to tell graph-depends where to store the generated dot
program, and keep stdout as the default if not specified.

Leverage the CSV files produces by size-stats (make graph-size) to allow
for a comparison of rootfs size between two different buildroot
compilations.
The script takes the file-size CSV files of two compilations as input, and
produces a textual report of the differences per package.
Using the -d/--detail flag, the report will show the file size changes
instead of package size changes.
The -t/--threshold option allows to ignore file size differences smaller
or equal than the given threshold (in bytes).
Example output is:
Size difference per package (bytes), threshold = 0

In some cases, the toolchain sources are now recovered and available in
the legal-info output. So, adapt the header to use conditional instead
of an definitive negation.
Also update the part about saving the sources: it's not the license list
that defines whether sources are installed, but rather whether the
package is redistributable or not.
Update the header accordingly.

In efe7f68 (support/download: generate reproducible Bazaar archives),
bzr was instructed to store files with the timestamp set to the date
they were last modified in the repository, instead of the current date,
using the --per-file-timestamp option.
However, this option has been added only in bzr-2.2 (August 2010) which
is not available on older distros.
We fix that by not using --per-file-timestamp when the bzr version is
older than 2.2, in which case we just generate the archive with the
current date set on files.
This means the archive is thus non-reproducible, and if a hash is
available for that archive, the hash will not match, and Buildroot will
try to download from the mirror (if any) or fail (if no mirror).

Similarly to what has previously been done for the Hg download backend,
instruct bzr to generate the archive on stdout, so that we can generate
reproducible archives.
When instructing bzr to generate the output file by itself, it uses a
temporary file that is then fed to gzip, which in turn stores the
timestamp of that file in the generated archive, whereas when the output
is generated on stdout, there is no timestamp, so the archive is then
reproducible.
Bizarely enough, we can tell 'bazaar' not to generate a bazaar in the
archive. Cool, uh? ;-]

When hg directly creates the output file, the hash for that file changes
everytime.
However, if we just tell hg to output the archive on stdout and we do
the redirect to the file, then the archive is reproducible.
(The reason is that in the first case, a temporary file is created and
then compressed, and gzip is adding the filename and its timestamp in
the gzip header, while in the second case, there is no temporary file,
and thus no timestamp and thus it is reproducible.)

For large configurations, the execution time of
remove_transitive_deps() becomes really high, due to the number of
nested loops + the is_dep() function being recursive.
For an allyespackageconfig, the remove_extra_deps() function takes 334
seconds to execute, and the overall time to generate the .dot file is
6 minutes and 39 seconds. Here is a timing of the different
graph-depends steps and the overall execution time:
Getting dependencies: 42.5735 seconds
Turn deps into a dict: 0.0023 seconds
Remove extra deps: 334.1542 seconds
Get version: 22.4919 seconds
Generate .dot: 0.0197 seconds
real 6m39.289s
user 6m16.644s
sys 0m8.792s
By adding a very simple cache for the results of is_dep(), we bring
down the execution time of the "Remove extra deps" step from 334
seconds to just 4 seconds, reducing the overall execution time to 1
minutes and 10 seconds:
Getting dependencies: 42.9546 seconds
Turn deps into a dict: 0.0025 seconds
Remove extra deps: 4.9643 seconds
Get version: 22.1865 seconds
Generate .dot: 0.0207 seconds

[yann.morin.1998@free.fr:
- rename is_dep() to is_dep_uncached(), keep existig code as-is
- add is_dep() as a cached-version of is_dep_uncached()
- use constructs more conform with 2to3
- use exceptions (EAFP) rather than check-before-use (LBYL) to be more
pythonist; that even decreases the duration yet a little bit more!

Some users may provide custom download commands with spaces in their
arguments, like so:
BR2_HG="hg --config foo.bar='some space-separated value'"
However, the way we currently call those commands does not account
for the extra quotes, and each space-separated part of the command is
interpreted as separate arguments.
Fix that by calling 'eval' on the commands.
Because of the eval, we must further quote our own arguments, to avoid
the eval further splitting them in case there are spaces (even though
we do not support paths with spaces, better be clean from the onset to
avoid breakage in the future).
We change all the wrappers to use a wrapper-function, even those with
a single call, so they all look alike.
Note that we do not single-quote some of the variables, like ${verbose}
because it can be empty and we really do not want to generate an
empty-string argument. That's not a problem, as ${verbose} would not
normally contain space-separated values (it could get set to something
like '-q -v' but in that case we'd still want two arguments, so that's
fine).

A series file for quilt has a valid syntax of:
fixes/autoconf.diff -p1
fixes/doc-html-local-css.diff -p1
fixes/gnu-inline.diff -p1
However, with the current way that a series file is handled, it will
error out because the -p1 is tried as a file. This is because in the
for loop that iterates the files, we only look for comment lines. Then
each line is used within a bash for loop which uses spaces a
delimiter. In order to fix this, we should only use the string that
comes before a space in the series file.
Note that the format allows for any arbitrary depth to the -pN field.
But since we'll have only one package with -pN fields, and all will be
-p1, we for now always assume -p1. This will have to be fixed whenever
we get a package with other values.

Despite the comment saying so, the trailing '/' in the host directory is
not removed. Note however that it is properly removed from extracted
RPATH tags.
This is not visible when the host directory is our default $(O)/host
location, but breaks for user-supplied external host directory, when
the user leaves a trailing slash in the path.
Fix that.
