The Buildroot coding style defines one space around make assignments and
does not align the assignment symbols.
This patch does a bulk fix of offending packages. The package
infrastructures (or more in general assignments to calculated variable
names, like $(2)_FOO) are not touched.
Alignment of line continuation characters (\) is kept as-is.
The sed command used to do this replacement is:
find * -name "*.mk" | xargs sed -i \
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#'
Brief explanation of this command:
^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line
\([?:+]\?=\) any assignment character =, :=, ?=, +=
\([^\\]\+\) any string not containing a line continuation
\([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a
line continuation character
\(\s*\\\) optional whitespace, followed by a line
continuation character
Hence, the first subexpression handles empty assignments, the second
handles regular assignments, the third handles regular assignments with
line continuation, and the fourth empty assignments with line
continuation.
This expression was tested on following test text: (initial tab not
included)
FOO = spaces before
FOO = spaces before and after
FOO = tab before
FOO = tab and spaces before
FOO = tab after
FOO = tab and spaces after
FOO = spaces and tab after
FOO = \
FOO = bar \
FOO = bar space \
FOO = \
GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse
FOO += spaces before
FOO ?= spaces before and after
FOO :=
FOO =
FOO =
FOO =
FOO =
$(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C
AT91BOOTSTRAP3_DEFCONFIG = \
AXEL_DISABLE_I18N=--i18n=0
After this bulk change, following manual fixups were done:
- fix line continuation alignment in cegui06 and spice (the sed
expression leaves the number of whitespace between the value and line
continuation character intact, but the whitespace before that could have
changed, causing misalignment.
- qt5base was reverted, as this package uses extensive alignment which
actually makes the code more readable.
Finally, the end result was manually reviewed.

The inner-xxx-targets in the buildroot package infrastructures are
evaluated using $(eval) which causes variable references to be a bit
different than in regular make code. As we want most references to be
expanded only at the time of the $(eval) we should not use standard
references $(VAR) but rather use double dollar signs $$(VAR). This includes
function references like $(call), $(subst), etc. The only exception is the
reference to pkgdir/pkgname and numbered variables, which are parameters to
the inner block: $(1), $(2), etc.
This patch introduces consistent usage of double-dollar signs throughout the
different inner-xxx-targets blocks.
In some cases, this would potentially cause circular references, in
particular when the value of HOST_FOO_VAR would be obtained from the
corresponding FOO_VAR if HOST_FOO_VAR is not defined. In these cases, a test
is added to check for a host package (the only case where such constructions
are relevant; these are not circular).
Benefits of these changes are:
- behavior of variables is now again as expected. For example, setting
$(2)_VERSION = virtual in pkg-virtual.mk will effectively work, while
originally it would cause very odd results.
- The output of 'make printvars' is now much more useful. This target shows
the value of all variables, and the expression that led to that value.
However, if the expression was coming from an inner-xxx-targets block, and
was using single dollar signs, it would show in printvars as
VAR = value (value)
while if double dollar signs are used, it would effectively look like
VAR = value (actual expression)
as is intended.
This improvement is for example effective for FOO_DL_VERSION, FOO_RAWNAME,
FOO_SITE_METHOD and FOO_MAKE.
The correctness of this patch has been verified using 'make printvars',
'make manual' and 'make legal-info' before and after applying this patch,
and comparing the output.

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.

cset 7a58a4e (e2fsprogs: bump to version 1.42.9) broke the generation
of ext4 filesystems.
This is because, in ext4, some metadata are dependent on the UUID.
If changing the UUID of an ext4 filesystem, tune2fs now exits with
exit-code 1, and prints a message to run fsck, to avoid trashing the
filesystem.
This condition is of utmost importance on a mounted filesysten (which
is not our case) to avoid corruption (yes, it is possible to change
the UUID of a mounted filesystem).
But the error is not valid for us, since we are working on an unmonted
filesystem image in the first place.
Since we change the UUID after we convert the filesystem (to ext4),
tune2fs just bails out.
We can not just ignore the exit code of tune2fs, since we still want
to catch any other failure.
It turns out that, changing the UUID before converting the filesystem
is just the way to go.
Fixes#6752.

When a package A depends on config option B and toolchain option C, then
the comment that is given when C is not fulfilled should also depend on B.
For example:
config BR2_PACKAGE_A
depends on BR2_B
depends on BR2_LARGEFILE
depends on BR2_WCHAR
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
This comment should actually be:
comment "A needs a toolchain w/ largefile, wchar"
depends on BR2_B
depends on !BR2_LARGEFILE || !BR2_WCHAR
or if possible (typically when B is a package config option declared in that
same Config.in file):
if BR2_B
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
[other config options depending on B]
endif
Otherwise, the comment would be visible even though the other dependencies
are not met.
This patch adds such missing dependencies, and changes existing such
dependencies from
depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
depends on BR2_BASE_DEP
depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.

Initramfs compression does not make much sense for the architectures
that support compressed kernel images because in this case the data
would be compressed twice. This will eventually result in a bigger
kernel image and time overhead when uncompressing it.
The only reason to use compressed initramfs is to reduce memory
usage when the kernel prepares rootfs, and both the unpacked
filesystem and initramfs.cpio are present in the memory.
Buildroot attempts to force GZIP compression for initramfs,
however it doesn't always work because initramfs compression mode
depends on RAM disk compression supported by the kernel.
Thus, CONFIG_INITRAMFS_COMPRESSION_GZIP depends on CONFIG_RD_GZIP.
If CONFIG_RD_GZIP is not set, setting GZIP initramfs compression
will have no effect.
Besides, the kernel also supports other compression methods,
like BZIP2, LZMA, XZ and LZO. Forcing the good old GZIP does not
really make much sense any more.
This removes initramfs compression settings from Buildroot,
so that the default value preset in the kernel config is used,
which is CONFIG_INITRAMFS_COMPRESSION_NONE.
If initramfs compression is still needed, it can be set
in the kernel config (using make linux-menuconfig)

genext2fs is built only if the user selected an ext2 root filesystem.
However, some use-cases can't live with the full target/ dir on the
root filesystem, and requires separate partitions (eg. for /usr).
In this case, the user would not select an ext2 root fs in the
Buildrooot menu, and would only generate a tarball of the rootfs.
This tarball would then be used from a post-image script to build
the actual required FSes.
But then, genext2fs is not built, since the ext2 root FS was not
selected.
As for the other filesystem generators, provide a host variant of
genext2fs (genext2fs is already host-package aware, so only needs
