Currently, the output of printvars copntains the name of the variable,
its expanded value and its un-expanded value.
However, most of the time, we need the actual, expanded value, so it can
be re-used from a (non-Buildroot) infrastructure script, like a
post-build script, or a build-farm driver (e.g. a Jenkins job...)
Add two options that a user may set to change the output of printvars:
- QUOTED_VARS, if set, will quote the value
- RAW_VARS, if set, will print the unexpanded value
The new output by default only prints the expanded value now.
So that it can be used as such:
$ make -s printvars VARS=BUSYBOX_VERSION
BUSYBOX_VERSION=1.26.2
$ make -s printvars VARS=BUSYBOX_RDEPENDENCIES QUOTED_VARS=YES
BUSYBOX_RDEPENDENCIES='ncurses util-linux'
$ make -s printvars VARS=BUSYBOX_FINAL_PATCH_DEPENDENCIES RAW_VARS=YES
BUSYBOX_FINAL_PATCH_DEPENDENCIES=$(sort $(BUSYBOX_PATCH_DEPENDENCIES))
And it is even possible to directly evaluate it in a shell script:
eval $(make -s printvars VARS=BUSYBOX_VERSION QUOTED_VARS=YES)
Backward compatibility of the output is not maintained. It is believed
that scripts that depended on the previous output were very fragile to
begin with, because they had to filter the non-formatted output
(splitting on spaces or braces was not really possible, because values
could contain either).
Document printvars and its options in the manual; list it in the output
of 'make help'.

Since we now require Lua package names to start with "lua", it is likely
that the Buildroot name is different from the upstream LuaRocks name.
Add a feature to the luarocks-package infra that makes it easier to
handle this situation: the package can explicitly specify the upstream
name in PKG_NAME_UPSTREAM, and that name will be used in PKG_ROCKSPEC,
PKG_SOURCE and PKG_SUBDIR.
Add an explanation of this feature to the manual. To make the example
relevant, it is changed to lua-foo, where the upstream name is plain
foo. To avoid confusion with the dependency on a native library, that
dependency is renamed to bar.

We currently have two places where we recommend where BR2_DL_DIR
should be set: "Environment variables" and "Location of downloaded

the latter kind of endorses using ~/.bashrc.
We prefer suggesting the ~/.bashrc way since it avoids downloading the
same file multiple times, and anyway it's wise to have all the details
in a unique place. So remove the .config suggestion from "Environment

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.

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.

When using a br2-external tree, it is possible (as stated in our manual)
to implement whatever arbitrary extra make rules (such as flashing a
board, or extracting the rootfs in an NFS export...). Some of those
extra rules might be exposed to the user as new entry points that the
user can call by itself.
However, there is no way for the br2-external to advertise those new
rules in the help text.
We add the possibility to do so, by adding a new make rule, called
help-custom, advertised in our own help info.
It is up to the br2-external tree to provide whatever help text is
deemed necessary. The format of the help is completely free-form.
Note that we need to provide an empty, dummy help-custom rule, since it
is always advertised (making it .PHONY does not work). Since this rule
is empty, make gently reports that there is "Nothing to be done for
`help-local'", which is pretty well fitting when help-local was not
provided (either because there's no br2-external tree, or when the
br2-external tree does not provide it.

Thomas P. has sent a few big feedback mails recently that explain how a
patch should be formatted. Indeed, this was not explained much in the
manual, so add a section that explains how patches should be formatted.
This is based heavily on the feedback that Thomas P. gave. Also,
specific examples for new packages and version bumps are added.
This will allow us to refer to
https://buildroot.org/manual.html#submitting-patches
in the future instead of composing long mails.

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
--------------------------------------------------------------------------------
-8192 busybox
228572 added dmalloc
301584 added jq

- the default value if needed
- then dependencies of the 'depends on' category
- followed by dependencies of the 'select' form
- with eventually the help text

Currently, we forcibly override BR2_EXTERNAL when building the manual,
so as to avoid referring to packages therein from the manual.
However, when generating the lists of packages, we limit ourselves to
scanning for packages in (Buildroot's) TOPDIR and never search in
BR2_EXTERNAL. So, we do not really need to override BR2_EXTERNAL when
generating the manual to achieve the same result.
Furthermore, we're only looking for packages that are defined in the
sub-menu "Target packages", and never anywhere else, and especially not
in the sub-menu "User-provided options".
Finally, we're soon to completely eliminate use of BR2_EXTERNAL in
Kconfig altogether, so that would no longer have any impact anyway.
So, just leave BR2_EXTERNAL alone when generating the manual.

Currently, packages that need to exclude parts of the archives when
extracting (e.g. to gain space), like gcc or toolchain-external, have to
provide custom extract commands, just for the sake of adding a bunch of
--exclude directives when calling tar.
Add a new variable that packages may set, to provide a space-separated
list of patterns to exclude.

When building in a different output directory than the original build,
there will currently be a lot of ccache misses because in many cases
there is some -I/... absolute path in the compilation. Ccache has an
option CCACHE_BASEDIR to substitute absolute paths with relative paths,
so they wil be the same in the hash (and in the output).
Since there are some disadvantages to this path rewriting, it is made
optional as BR2_CCACHE_USE_BASEDIR. It defaults to y because the
usefulness of ccache is severely reduced without this option.
In addition to CCACHE_BASEDIR, we also substitute away the occurences
of $(HOST_DIR) in the calculation of the compiler hash. This is done
regardless of the setting of BR2_CCACHE_USE_BASEDIR because it's
quite harmless.

The "Dynamic using mdev" and "Dynamic using eudev" /dev management
methods are using devtmpfs, just like "Dynamic using devtmpfs only",
on top of which they add either mdev or eudev. But their names might
suggest they use mdev only or eudev only.
Clarify their descriptions by adding "devtmpfs +" to make it
unambiguous.

Because of a limitation in how makedevs resolves names [0], usernames
and groupnames would be resolved with UIDs and GIDs from the host, not
the target.
Fixing makedevs would involve us rewriting a /etc/passwd and /etc/group
parser (not too complex, still not trivial).
Document that the user and group fields should only be numbers, not
names. Also, the manual is currently misleading, as an example indeed
uses names for the user and group fields. Fix that and expand the
explanations.
The mode field should also be numbers, not a rwx combo.
Slight typographical eye-candy about major/minor fields.
[0] it uses getpwnma(3) and getgrnam(3) to resolve names to IDs, and
those only resolve names on the host (i.e. there is no way to specify
a chroot-like feature)
