a1d12fe939 get-developers: use --cc instead of --to for developers
Output of get-developers script in our manual uses --cc for developers,
but actual output of get-developers script uses --to. This patch makes
code consistent with documentation, by using --cc for developers.

5feff44038 core/br2-external: export paths and descriptions
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.

20cd497387 core: add support for multiple br2-external trees
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.

fc34cf772c core: introduce per br2-external NAME
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.

6bd19ccf0d core: offload handling of BR2_EXTERNAL into the script
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.

64e12a370c core: get rid of our dummy br2-external tree
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! ;-) )

0f4435e950 core: do not hard-code inclusion of br2-external in Kconfig
Move the inclusion of br2-external's Config.in to the generated kconfig
snippet.

This will ultimately allow us to use more than one br2-external tree.

Offload the "User-provided options" menu to the generated Kconfig
snippet. We can also move the definition of the Kconfig-version of
BR2_EXTERNAL into this snippet.

We introduce an extra check that was not present in the previous code,
to check that we do have permission on that directory. Prevciously, it
was handled as a side effect of not being able to cd into there, but it
is cleaner to check it expressly.

183d9b654c support/scripts/get-developers: add new script
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.

Examples of usage:

$ ./support/scripts/get-developers 0001-ffmpeg-fix-bfin-build.patch
git send-email--to buildroot@buildroot.org --to "Luca Ceresoli <luca@lucaceresoli.net>" --to "Bernd Kuhls <bernd.kuhls@t-online.de>"

d4db4277ff manual: get rid of the lists of packages
We currently have four lists of packages in the manual:

  - 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

34b1bdeba4 size-stats: fix bug when parsing file names with comma
The size-stats script fails when the usb_modeswitch_data is enabled,
because this package installs files that contain commas in their

  pkg, fpath = l.split(",")

Fix this by splitting only the two fields that need to be split.

1924159814 support/apply-patches: bail-out on duplicate patch basenames
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.

Instead of duplicating the logic to find the patches (bundled,

each of those patches so we can retrieve them more easily later on.

Also always create the list-file, even if empty, so that we need not

549bbba67f python/python3: globalize *.pyc files compilation
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.

88bad8f462 support/scripts: add helper to hardlink-or-copy
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.

ac031cfb97 support/scripts: fix graph-depends when run with python3
Make graph-depends script opening the output file in text mode since

This change fixes the following error occuring when the default host

  make: Entering directory '/opt/buildroot'
  Getting targets
  Getting dependencies for ['toolchain-external', 'toolchain', 'busybox', ...]
  Getting dependencies for ['host-python3', 'host-pkgconf', 'host-gettext', ...]

  Getting version for ['toolchain-external', 'toolchain', 'busybox', ...]
  Traceback (most recent call last):

  make[1]: *** [graph-depends] Error 1
  Makefile:84: recipe for target '_all' failed
  make: *** [_all] Error 2
  make: Leaving directory '/opt/buildroot'

While with python2, adding 'b' to the openning mode has no effect on
Linux (c.f. [2]), the above error is expected with python3 (c.f. [1]).

Therefore, just open the outfile in default (i.e. text) mode.

7771bb93b2 graph-depends: fix handling of "virtual" in exclude_list
The condition to determine if a virtual package should be excluded
from the list due to "virtual" being passed in --exclude is under a
loop iterating over each entry of the exclude_list, but it doesn't use
the iterator of this list.

Indeed, the condition contains:

	"virtual" in exclude_list

which checks automatically if "virtual" was passed in the list. Due to
this, there is no need for this check to be within the "for p in
exclude_list" iteration. This commit fixes that by moving the check
outside of the loop.

f48c08f0f5 support/graph-depends: detect circular dependencies
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:

a3f75bcc76 support/graph-depends: add option to specify output file
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.

8c5afd120e support/scripts: add size-stats-compare script
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

5ed60cee1e graph-depends: optimize remove_transitive_deps()
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

aab481c14e apply-patches: only use first field of line for series file
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.

5c0c385226 core: check host executables have appropriate RPATH
When we build our host programs, and they depend on a host library we
also build, we want to ensure that program actually uses that library at
runtime, and not the one from the system.

We currently ensure that in two ways:
  - we add a RPATH tag that points to our host library directory,
  - we export LD_LIBRARY_PATH to point to that same directory.

With these two in place, we're pretty much confident that our host
libraries will be used by our host programs.

However, it turns our that not all the host programs we build end up
with an RPATH tag:
  - some packages do not use our $(HOST_LDFLAGS)
  - some packages' build system are oblivious to those LDFLAGS

In this case, there are two situations:
  - the program is not linked to one of our host libraries: it in fact
    does not need an RPATH tag [0]
  - the program actually uses one of our host libraries: in that case it
    should have had an RPATH tag pointing to the host directory.

For libraries, they only need an RPATH if they depend on another library
that is not installed in the standard library path. However, any system
library will already be in the standard library path, and any library we
install ourselves is in $(HOST_DIR)/usr/lib so already in RPATH.

We add a new support script that checks that all ELF executables have
a proper DT_RPATH (or DT_RUNPATH) tag when they link to our host
libraries, and reports those file that are missing an RPATH. If a file
missing an RPATH is an executable, the script aborts; if only libraries
are are missing an RPATH, the script does not abort.

[0] Except if it were to dlopen() it, of course, but the only program
I'm aware of that does that is openssl, and it has a correct RPATH tag.

that manipulate series files don't support compressed patches).

474d39a1ff Makefile: Remove 'quiet' variable
'quiet' variable is set and exported, but it is not used. We can safely
remove it.

This variable is inherited from the Makefile of the Linux kernel, and
is not used in Buildroot.

In support/scripts/mkmakefile, 'quiet' value is checked, but the test
is always true ('quiet' is never set to silent_), so the test can be
removed as well.
