3fbd9887b3 filesystems: also chown symlinks
Currently, the symlinks in the generated filesystems will have the
UID of the user running the build, because 'chown' does not change
the ownership of symlinks, by default.

Although the implications are limited, some may not want that UID
to leak in the generated filesystems.

So, use 'chown -h' so even symlinks get properly chowned.

4d922634da support/scripts: generate a list of virtual packages
Generate an asciidoc table that can be included in the manual, that
lists the existing virtual packages, the corresponding symbols, and
their providers (and sub-options thereof).

The core of this change is the addition of a new formatter for virtual
packages. This formatter is a bit tricky, as it has to catter for a
bunch of corner cases:
  - provider is not a package, but is sub-options of a package
  - such a sub-option may be itself 'select'-ed by one or more
    other sub-options
  - legacy packages should not be considered as a provider

Those cases are real:
  - sub-options of mesa3d provide EGL or GLES
  - selected sub-options of mesa3d provide GL
  - udev is a legacy package, but it provides udev

fe696d7c65 support/scripts: introduce a symbol formatter to generate package lists
Currently, we can generate two different tables of packages:
  - a single-column table with the symbols' prompts,
  - a two-column table with the symbols' prompts and locations in the
    menuconfig.

For virtual packages, this is not enough, since we will have to display
more columns, with different content:
  - the virtual package name (but such symbols do not have a prompt)
  - the symbol name
  - the providers for the virtual package

So, instead of having a single function that knows how to generate any
table, introduce a formatter function that is passed as argument to,
and called by format_asciidoc_table(). Such formatter functions are
responsible for providing:
  - the layout of the table (number of columns, column arrangement),
  - the formatted header line,
  - a formatted line for a symbol.

What the formatter should ouput depends on its arguments:
  - if none are passed, the layout is returned,
  - if the header label is passed, it returns the formatted header line,
  - otherwise, it returns the formatted line for a symbol.

Two formatter functions are introduced in this changeset, to replace the
current 'sub_menu' feature:
  - _format_symbol_prompt() to display a one-column table with only the
    symbols' prompts,
  - _format_symbol_prompt_location() to display a two-column table with
    the symbols' prompts and locations.

This will help us to later introduce a new formatter to generate a table
for virtual packages.

[Thanks to Samuel for his pythonistic help!]

b2c75ecc5d support/scripts: who's responsible to decide what is a package
When generating the package lists, the responsibility to decide what is
actually a package symbol is currently split between the _is_package(),
the get_symbol_subset() and the format_asciidoc_table() functions.

The two latter functions check that an item is really a symbol, and that
is has a prompt.

While this is currently correct for real packages, this will no longer
be the case when we also generate a list of virtual packages, since they
do not have a prompt.

Move the responsibility to verify that a symbol is indeed a package symbol
to _is_package(), so it's all in one place, and makes it easier to change
for virtual packages.

f93edd823f support/scripts: do not display virtual packages in generated lists
If a package has both a 'real' and a 'virtual' definition, consider it
is a virtual package and do not display it in the generated package list.

This is the case for jpeg and cryptodev, that are virtual packages, but
also real (but empty) packages used to provide a prompt to enable/disable
a choice to select an implementation. In this case, we do not want to
list the virtual packages, but only their implementations.

So, consider packages that are both real and virtual as virtual packages.

e49d4f0c37 support/scripts: prepare handling virtual packages in generated lists
Prepare to tell apart real packages from virtual packages.

Currently, the code implicitly recognises only real packages, and
discards virtual packages, because of the heuristic used to recognise
whether a symbol is a package:

  - for real package:
    - symbols  : BR2_PACKAGE_FOO
    - .mk files: foo.mk
  - for virtual packages:
    - symbols  : BR2_PACKAGE_HAS_FOO
    - .mk files: foo.mk

The current heuristic is to check for each symbol if a corresponding .mk
file exists, by stripping 'BR2_PACKAGE_' from the beginning of the symbol,
converting the result to lowercase, and checking if a .mk file exists.

So, as a side effect, it completely misses the virtual packages [*], which
is pretty nice since we get a list with only real packages that the user
can indeed select and see in the menuconfig.

[*] Except for 'cryptodev' and 'jpeg' which are both virtual packages and
normal packages. Except they are not normal packages, they are used to
display a choice of the implementation to use. This case will be fixed in
follow-up patches.

Since we'll soon need to also output the table of virtual packages, we
need to teach the _is_package() function to recognise them as well.

This patch is the first step into that direction: it introduces a new
function _is_real_package() that is just a wrapper to _is_package(), which
gains a new parameter, being the type of packages to filter on.

No behavioural change is made in this patch, it is just a preparatory
patch.

95ab905ba7 graphs-depends: merge redundant-dependencies elimination
Merge the redundant-dependencies elimination into the newly introduced
transitive-dependencies elimination.

This makes the code cleaner and much shorter, because:

  - the ('all',pkg) redundant dependency is in fact a transitive
    dependency, and we now have code to deal with that

  - the (pkg,'toolchain') dependency is easy enough to deal with that
    having a separate function for that is overkill

67957967a5 graphs: add option to remove transitive dependencies in dependency graph
Currently, all the dependencies of a package are drawn on the dependency
graph, including transitive dependencies (e.g. A->B->C and A->C).

For very big graphs, with lots of packages with lots of dependencies, the
dependency graph can be very dense, and transitive dependencies are
cluttering the graph.

In some cases, only getting the "build-order" dependencies is enough (e.g.
to see what impact a package rebuild would have).

Add a new environment variable to disable drawing transitive dependencies.

Basically, it would turn this graph:

    pkg1 ---> pkg2 ---> pkg3 -------------------.
         |\__________/                 \         \
         |\____________________         \         \
         |                     \         \         \
          `-> pkg4 ---> pkg5 ---> pkg6 ---> pkg7 ---> pkg8
                    \__________/

into that graph:

    pkg1 ---> pkg2 ---> pkg3 -----------.
         |                               \
          `-> pkg4 ---> pkg5 ---> pkg6 ---> pkg7 ---> pkg8

c8f2d248f6 pkg-cmake.mk: enable ccache for cmake packages
This patch updates the generated toolchainfile.cmake to use ccache.

When toolchainfile.cmake is used inside Buildroot, using ccache during
the build is driven by a CMake knob: USE_CCACHE, automatically set by
the cmake-package infrastructure and reflecting the BR2_CCACHE value.

Since this toolchainefile.cmake file can be used outside Buildroot, and
this file also set a couple of things (among these: the sysroot cflag,
some pkg-config environment variables), it is important to set the
compiler variables as well to keep the consistency of the
cross-compilation configuration.
So, when it is used outside Buildroot, using ccache for the build is
driven by the ccache program availability.

Note that using ccache for the build is achieved by setting the *_ARG1
CMake variables to let CMake use ccache without failing in detecting
the compiler.

2a82bb8a90 support/check-kernel-headers: fix old custom toolchains without -print-sysroot
Old toolchains, with old gcc that do not support -print-sysroot, break the
kernel-headers version check script: it fails to find the sysroot of the
toolchain, and thus ends up including the host's linux/version.h.

Most of the time, this will break early, since the host's kernel headers
will not match the toolchain settings.

But it can happen that the check is succesful, although the configuration
of the toolchain is wrong:

  - the custom toolchain has kernel headers vX.Y
  - the user selected vX.Z  (Z!=Y)
  - the host has headers vX.Y

In this case, the check passes OK, but the build of some packages later on
will break (which is exactly what those _AT_LEAST_XXX options were added to
avoid).

Fix that by passing the sysroot to the check script, instead of the cross
compiler.

We get the sysroot as thus:

  - for custom toolchains, we use the macro toolchain_find_sysroot. We can
    do that, because we already have a complete sysroot with libc.a at that
    time.

  - for internal toolchain using a custom kernel headers version, we just
    use $(STAGING_DIR). We can't use the macro as for custom toolchains
    above, because at the time we install the kernel headers, we do not yet
    have a complete sysroot with a libc.a.  But we can just use
    $(STAGING_DIR), since we're only interested in the kernel headers.

For all other types of toolchains, we already have the _AT_LEAST_XXX options
properly set, so we need not add a check in this case.

Fixes:

0aa9019c2d toolchain: print actual version of kernel headers when checking
Since we introduced the _AT_LEAST_XXX for the kernel headers, people
using pre-built custom toolchain now have to specify the version of
the kernel headers their custom toolchain uses.

So, when we detect that there is a mismatch between the selection in
the menuconfig, and the actual version of the headers, we currently
only bail out with a terse message "Incorrect selection of kernel
headers".

This could be confusing some, and getting the version of the headers
used by the toolchain is not trivial (well, it's very easy, but not
trivial.)

This patch changes the way we report the error by moving the message
into the test-code, and by printing the expected and actual versions
of the kernel headers.

BUT! To get this pretty error message, we need to run the
test-program, so we can not use the cross-toolchain, we have to use
the native one.

BUT! The native one has its own linux/version.h header, so we can not
simply include it.

So, we ask the cross-compiler where its default sysroot is, and use
that to then force-feed the cross linux/version.h to the native
toolchain.

[Thomas: augment commit log with a message provided by Yann, fix
coding style to not have spaces after opening parenthesis and before
closing parenthesis, reformatted the message "Incorrect selection..."
to make it fit on one line.]

4955a31cec support/mkusers: fix warnings when adding a new user
When adding a new user (or a new group), we would get warnings, like:
  [...]/support/scripts/mkusers: line 145: [: too many arguments

This is because we're checking if a UID (or a GID) is already defined,
and/or is different from the requested one, both checks in the same
test.

Of course, if a UID (or a GID) is not defined, it does not have a value,
so we can not compare it to an integer.

Fix that by splitting the test in two, so the second is only executed if
the first is sucessful.

a5a309642a toolchain/external: check kernel headers version for custom toolchain
Ensure the kernel headers version used in the custom external toolchain,
or the manually-specified kernel headers version, matches exactly the one
selected by the user.

We do not care about the patch-level, since headers are not supposed to
change between patchlevels. This applies only to kernels >= 3.0, but
those are actually the ones we do care about; we treat all 2.6.x kernels
as being a single version, since we do not support any 2.6 kernels for
packages with kernel-dependant features.

aac3d2b402 infra: Introduce BR2_HOST_NEEDS_JAVA
XBMC needs Java on the host in order to build, because it uses a
code-generator which is built in two phases: In the first phase SWIG is used
to parse C++ header files that define the API.  SWIG outputs an XML file
that contains a complete description of the structure of the API.  In the
second phase, the XML file is ingested by a Groovy (Java) program that then
creates C++ code that forms the bridge to the scripting language (Python).

The second phase is why we need java on the host.

You can learn more at the XBMC's wiki:
http://wiki.xbmc.org/index.php?title=Codegeneration#How_it_works

In order to check that, this patch introduce this mechanism in
dependencies.sh, and it also defines the variable in Config.in

14cdf705c6 apply-patches.sh: make scan_patchdir work recursively
scan_patchdir is called recursively. For this to work properly, the
variable path which is set to $1 at the very beginning must be local not
global.

A test case is to set BR2_GLOBAL_PATCH_DIR to 'mypatches' and having the
following tree in the buildroot root:

$ find mypatches/
mypatches/
mypatches/busybox
mypatches/busybox/subdir.patch
mypatches/busybox/subdir.patch/busybox-0001-abc.patch
mypatches/busybox/busybox-0002-def.patch
mypatches/busybox/asubdir.patch
mypatches/busybox/asubdir.patch/busybox-0003-xyz.patch

When running 'make busybox-dirclean busybox-patch' originally, you'd get:

    Applying busybox-0003-xyz.patch using patch:

    Applying busybox-0002-def.patch using patch:
    Error: missing patch file
    mypatches/busybox/asubdir.patch/busybox-0002-def.patch

While with this fix:

    Applying busybox-0003-xyz.patch using patch:

    Applying busybox-0002-def.patch using patch:

    Applying busybox-0001-abc.patch using patch:

BR2_HOSTARCH_NEEDS_IA32_COMPILER.  This triggers a test in dependencies.sh
to verify the host compiler can build 32 bit executables.  Currently this
test does not set any output for the compiler which causes a stray a.out
to be create outside the output directory.  This patch sets the compiler
output to /dev/null so no a.out is created but the test is still performed.

136ede6f19 scripts: xorg-release: handle case when version needs downgrade
the initial implementation assumes that when a version found in
buildroot is different from the one in the X11 release, it
requires an upgrade. even though this is most likely the case, it
could be a downgrade too, and it's probably worth highlighting
such cases when it (rarely) happens.

LooseVersion from distutils is doing the low level job of sorting
version numbers represented in strings...

[Thomas & Thomas:

  - do not count packages more recent in Buildroot than in the latest
    X.org release as to be downgraded. If we have more recent version,
    it's generally for a good reason, so we want to keep them as
    is. Such packages are counted as "nothing to do", but for
    information, we indicate that there are "More recent"

  - also remove the "nothing to do" action indicator. It used to be a
    simple dash, which was not really useful.

'printf' was introduced because it is more portable than 'echo -e'. But
when the escape sequences are just newlines we can just as well use
plain 'echo' (and remove the newline escape sequences).

This looks cleaner than having some lines with echo and some with
printf.

221ef3a3ee Prefer 'printf' over 'echo -e' (for portability)
support/dependencies/dependencies.sh uses #!/bin/sh shebang. It is not
guaranteed that /bin/sh provides an 'echo' implementation that
understands the '-e' flag (interpret backslash escape chars). For
example, dash doesn't.

'printf' is more portable (it must interpret backslash escape chars,
according to POSIX), so use that.

NOTE: Before the previous commit, the dependencies.sh script used
/bin/echo instead of the shell built-in. That's probably why this hasn't
come up before.

ba4ad9d27c deprecated handling: introduce BR2_DEPRECATED_SINCE_xxxx_xx
In order to keep better track of when a feature got deprecated, and hence
when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is
introduced. These symbols are automatically selected when BR2_DEPRECATED is
selected, and thus are transparent to the user.
A deprecated feature will no longer depend on BR2_DEPRECATED directly, but
rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does
not yet exist, it has to be created in Config.in.
When removing a deprecated feature, one should also check whether this was
the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which
case the latter can be removed from Config.in.

A followup patch will make sure the overview is added to the list of
deprecated features in the manual, so that a buildroot core developer can
easily determine which features to remove in a given development cycle.

7d656636bd graph-build-time: generate graphs based on timing data
This script generates graphs of packages build time, from the timing
data generated by Buildroot in the $(O)/build-time.log file.

Example usage:

  ./support/scripts/graph-build-time \
      --type=histogram --input=$(O)/build-time.log --output=foobar.pdf

Three graph types are available :

  * histogram, which creates an histogram of the build time for each
    package, decomposed by each step (extract, patch, configure,
    etc.). The order in which the packages are shown is
    configurable: by package name, by build order, or by duration
    order. See the --order option.

  * pie-packages, which creates a pie chart of the build time of
    each package (without decomposition in steps). Packages that
    contributed to less than 1% of the overall build time are all
    grouped together in an "Other" entry.

  * pie-steps, which creates a pie chart of the time spent globally
    on each step (extract, patch, configure, etc...)

The default is to generate an histogram ordered by package name.
