The variable 'KERNEL_ARCH' is actually a normalized version of
'ARCH'/'BR2_ARCH'. For example, 'arcle' and 'arceb' both become 'arc', just
as all powerpc variants become 'powerpc'.
It is presumably called 'KERNEL_ARCH' because the Linux kernel is typically
the first place where support for a new architecture is added, and thus is
the entity that defines the normalized name.
However, the term 'KERNEL_ARCH' can also be interpreted as 'the architecture
used by the kernel', which need not be exactly the same as 'the normalized
name for a certain arch'. In particular, for cases where a 64-bit
architecture is running a 64-bit kernel but 32-bit userspace. Examples
include:
* aarch64 architecture, with aarch64 kernel and 32-bit (ARM) userspace
* x86_64 architecture, with x86_64 kernel and 32-bit (i386) userspace
In such cases, the 'architecture used by the kernel' needs to refer to the
64-bit name (aarch64, x86_64), whereas all userspace applications need to
refer the, potentially normalized, 32-bit name.
This means that there need to be two different variables:
KERNEL_ARCH: the architecture used by the kernel
NORMALIZED_ARCH: the normalized name for the current userspace architecture
At this moment, both will actually have the same content. But a subsequent
patch will add basic support for situations described above, in which
KERNEL_ARCH may become overwritten to the 64-bit architecture, while
NORMALIZED_ARCH needs to remain the same (32-bit) case.
This commit replaces use of KERNEL_ARCH where actually the userspace arch is
needed. Places that use KERNEL_ARCH in combination with building of kernel
modules are not touched.
There may be cases where a package builds both a kernel module as userspace,
in which case it may need to know about both KERNEL_ARCH and
NORMALIZED_ARCH, for the case where they differ. But this is to be fixed on
a per-need basis.

The current printvars output suffers from a serious design flaw:
variables are not delimited, which makes it impossible to reliably
retrieve the value of variables; only variables that are known to
not contain a \n can be relatively safely extracted.
However, in some cases, it is important to be able to retrieve the
multi-line value of a variable, notably the CMDS or the hooks. One
such use-case (to follow in an unscheduled future) would be to hash
the variables that make up a package "configuration", and cache or
extract the files for that package to speed up the build.
Modeled after printvars and show-info, we introduce show-vars (what a
lack of imagination here) that outputs a json dictionary which keys are
the variable names, and for each variable, provides the raw and expanded
values.
Unlike printvars, we do not provide a way to get either the raw or
expanded value; both are systematically printed; a user will get just
the one is needs. Additionally, strings in JSON are quoted, so there is
no need to provide a way to quote variables; that would not make sense.
Note: for printvars, we require that the user provides an explicit
pattern to filter variables on. This is historical (see fd5bd12379,
Makefile: printvars: don't print anything when VARS is not set). The
underlying reasoning was that printvars is too "raw", and variables are
not well delimited, so printvars was mostly used to extract a few values
here and there, from scripts, or to quickly inspect a specific package's
variables during debugging.
But show-vars, although technically plain-text, being JSON, is not very
human-readable, and is mostly aimed at tools that will parse it with a
real JSON parser, and which will want to have a complete view of a lot
of variables at once. As such, and contrary to printvars, it makes sense
to report on all variables by default, unless the user explicitly
requested a subset.
As a final note: a lot of our variables only make sense in the context
of an actual make target. For example, a variable of package foo, that
contains $(@D)/bar, would expand to .../build/FOO-VERSION/bar. This is
because our CMDS and hooks are expanded as the recipe of a stamp file
that lies in the package build directory.
But for show-info, this falls flat on its face: it is not the stamp file
of a package, so there is no package directory, and show-info itself has
not directory part, so $(@D) expands to '.' (dot).
Additionally, some variables may contain calls to $(shell) (e.g. to call
pkg-config), and this also does not work with show-info.
These two issues make it impossible to emit the correct expanded value
of variables. To be noted: printvars has the exact same limitations for
the exact same reasons.

Set HOSTCC_NOCCACHE and HOSTCXX_NOCCACHE only if they are not
set. This allows recursive calls to "make" to work as intended in the
presence of ccache. Such recursive calls to "make" can for example
happen if one calls "make legal-info" from within a post-build script,
to integrate some results of the legal-info output into the root
filesystem.
Without guarding these variables, a recursive invocation of make would
re-define
HOSTCC_NOCCACHE := $(HOSTCC)
and
HOSTCXX_NOCCACHE := $(HOSTCXX)
at a point in time when HOSTCC and HOSTCXX already point to ccache.
It used to work by "accident" until
ca6a2907c2 ("make: support: use `command
-v' instead of `which'"), due to how "which" was behaving when invoked
with multiple arguments. After switching to "command -v", which
behaves different with multiple arguments, this HOSTCC_NOCCACHE
redefinition problem surfaced. Even though
ca6a2907c2 has since then been reverted
for other reasons, it does make sense to guard the definition of
HOSTCC_NOCCACHE and HOSTCXX_NOCCACHE to not rely on a side-effect of
using "which".

Parallelizes locale generation based on `BR2_JLEVEL` setting.
Locale generation always runs during the finalize stage and can consume
a significant amount of time. Parallelizing it greatly reduces that time
on multi-core machines.
To parallelize it, we first invoke `localedef` for every locale in
parallel with the `--no-archive` option. This creates the intermediate
locale data instead of writing to the finally archive directly.
Then, we invoke `localedef` again once to create the archive from the
intermediate compiled locale data files.
We have to do it this way because `localedef` does not do any locking
when writing to the archive file, so calling it without `--no-archive`
concurrently could result in a corrupt archive file or an archive file
that is missing some locales.
While we're at it, make two additional improvements:
- Remove locale-archive before adding to it. Otherwise, repeated
applications of target-finalize will keep on growing the file.
- Sort the locales when creating locale-archive so its contents are
reproducible.
We use `find` to collect the installed locales rather than LOCALES. This
makes it possible for something else (skeleton, overlay, custom package)
to create and install additional locales and still have them added to
locale-archive.

Commit 7d17ae2acf (.flake8: fix check for 80/132 columns) introduced a
difference in how flake8 behaves between the automatic checks done in
the CI, where the maximum line length is 132, and the local checks,
where the maximum line length is 80.
The rationale at the time was that we recommend 80 char lines, but that
we accept 132 when it makes sense for readability.
However, this is very annoying when running flake8 locally, because of
two reasons:
1. human reviews on python scripts have not been as thorough as we did
expect; indeed, we've let a lot of long lines slip through; this
causes a lot of spurious failures that hide away the actual errors;
2. when hacking on a python script, the issues reported will not be
caused by the current changes, so the many reported failures
actually hide away the newly introduced issues.
Additionally, our 'make check-flake8' rule already enforces the 132-char
limit, and the issues reported are different than when manually running
flake8 on individual files.
Furthermore, the readability rationale for the 80-char limit is
definitely shattered by the mere rationale of allowing 132-char limit
for... readability...
We've arrived to a point where this separation is causing our checks
around flake8 to become mostly unusable and useless, as they do not
report meaningful issues, and people are no longer paying attention, and
this has caused actual issues to be introduced.
Finally, terminal emulators of today have long lifted the 80-char limit,
and are more than capable of displaying 132-char wide lines.
Switch back to using a 132-char limit.
This reverts commit 7d17ae2acf.

Although BR2_DL_DIR is indeed a site-local setting, which does not
actually define the target system, we've had it in the tree for a
long time now, and people have been depending on it for a variety
of use-cases.
Furthermore, BR2_DL_DIR is far from the only such site-local setting,
BR2_CCACHE_DIR springs to mind, and in the less-obvious category, we
can also find BR2_JLEVEL, but also BR2_WGET, BR2_SVN, BR2_GIT et al.
as they may be tweaked to set the timeout, number of retries or so on
to work around stupid proxies. But of course, the most local site-local
setting is probably BR2_PACKAGE_OVERRIDE_FILE, with its default value
being explicitly just 'local.mk'.
Ideally, we would like to have a clear separation between the
configuration that actually defines the target system on one hand,
and the site-local settings that drive and control how the build is
performed, on the other hand. This is by far a much bigger endeavour
than just dropping BR2_DL_DIR from the saved defconfig.

is only valid locally.
However, we were not careful to really match the exact variables, so we
could match arbitrary options.
For example, these config options would all be dropped:
BR2_DEFCONFIG="toto"
BR2_DL_DIR="titi"
BR2_PACKAGE_SABR2_DEFCONFIG="tutu"
BR2_PACKAGE_SABR2_DL_DIR=y
While the first two are indeed the ones we want to drop, the last two
are options (whatever their meaning or how poorly named they are) of the
hypothetical 'sabr2' package, and we want to keep those in a defconfig.

Move the code to run check-flake8 into the Makefile, like we have for
check-package, so that it is easy to run locally (and not wait for
someone to report a failure from their Gitlab pipelines).
Compared to the existing check from gitlab-ci.yml, the Makefile check
differs in this respect:
- don't explicitly find *.py files: they are supposed to also be found
as a result of running 'file' on them;
- use git ls-tree instead of find: this is supopsedly faster as it
uses the index rather than readdir();
- don't output the count of warnings or errors: the output is a single
integer, which is confusing when there are errors, and even more so
when there are no, when it is simply '0';
- don't sort: the output is already stable and independent from the
locale;
- don't report the number of processed files: this information is
rather useless, and getting a hold of it would be more challenging
in this new code.
Note: ideally, we would want to use --null, --zero, or similar options,
with utilities that generates or parses a files listing. While git
ls-tree and xargs do support it, it becomes a little bit tricky to use
the --print0 option of file, and then grep in that output (it is not
undoable, but would requires replacing grep+cut with some sed trickery).
Since we do not expect our scripts names to contain funky chars (like
\n or a colon), we just hand-wave away that issue (and the old code was
doing the same assumption too).

BR2_VERSION_FULL is currently defined as follows:
BR2_VERSION_FULL := $(BR2_VERSION)$(shell $(TOPDIR)/support/scripts/setlocalversion)
This BR2_VERSION_FULL value then gets used as the "VERSION" variable
in the /etc/os-release file.
The logic of "setlocalversion" is that if it is exactly on a tag, it
returns nothing.
If it is on a tag + a number of commits, then it returns only
-XYZ-gABC where XYZ is the number of commits since the last tag, and
ABC the git commit hash (these are extracted from git describe).
This output then gets concatenated to BR2_VERSION which gives
something like 2020.05 or 2020.05-00123-g5bc6a.
The issue is that when you're on a tag specific to your project, which
is not a Buildroot YYYY.MM tag, then the output of setlocalversion is
empty, and all you get as VERSION in os-release is $(BR2_VERSION)
which is not really nice. Worse, if you have another non-official
Buildroot tag between the last official Buildroot tag/version and
where you are, you will get $(BR2_VERSION)-XYZ-gABC, but XYZ will not
correspond to the number of commits since BR2_VERSION, but since the
last tag that "git describe" as found, which is clearly incorrect.
Here is an example: you're on master, "make print-version" (which
displays BR2_VERSION_FULL) will show:
$ make print-version
2020.08-git-00758-gc351877a6e
So far so good. Now, you create a tag say 5 commits "before" master,
and show BR2_VERSION_FULL again:
$ git tag -a -m "dummy tag" dummy-tag HEAD~5
$ make print-version
2020.08-git-00005-gc351877a6e
This makes you believe you are 5 commits above 2020.08, which is
absolutely wrong.
So this commit simplifies the logic of setlocalversion to simply
return what "git describe" provides, and not prepend $(BR2_VERSION) in
the main Makefile. Since official Buildroot tags match official
Buildroot version names, you get the same output when you're on an
official Buildroot tag, or some commits above a Buildroot tag. An in
other cases, you get a sensible output. The logic is also adjusted for
the Mercurial case.
In the above situation, with this commit applied, we get:
$ make print-version
dummy-tag-6-g6258cdddeb
(6 commits instead of 5 as we have this very commit applied, but at
least it's 6 commits on top of the dummy-tag)
Finally, if you're not using a version control system, setlocalversion
was already returning nothing, so in this case, the Makefile simply
sets BR2_VERSION_FULL to BR2_VERSION to preserve this behavior.

The rule to create the staging symlink has it depend on BASE_DIR, and

As a consequence, every time one runs 'make', the symlink will be older

Post-build scripts may want to do something based on the list of files
installed by a package. However, since commit
0e2be4db8a the final packages-file-lists.txt
file is only created _after_ the post-build scripts.
Move the assembly of the file lists upwards, before the post-build scripts.

In very limited configurations, it is possible to have a case where no
.files-list-staging.txt files are created. In this case:
cat $(sort $(wildcard $(BUILD_DIR)/*/.files-list-staging.txt)) > \
$(BUILD_DIR)/packages-file-list-staging.txt
becomes:
cat > \
$(BUILD_DIR)/packages-file-list-staging.txt
which of course makes the build hang.. forever.
So we fix this by checking the list is not empty. To keep the code
readable, we introduce an intermediate variable to store the list of
these files.

With BR2_PER_PACKAGE_DIRECTORIES=y, we have the following code in the
main Makefile:
target-finalize: $(PACKAGES) $(TARGET_DIR) host-finalize
@$(call MESSAGE,"Finalizing target directory")
$(call per-package-rsync,$(sort $(PACKAGES)),target,$(TARGET_DIR))
$(foreach hook,$(TARGET_FINALIZE_HOOKS),$($(hook))$(sep))
The per-package-rsync call creates the global $(TARGET_DIR) from the
per-package $(TARGET_DIR). Then, we call the TARGET_FINALIZE_HOOKS.
One of the TARGET_FINALIZE_HOOKS, PURGE_LOCALES, remove locales that
are not desired by the user. It does so using a loop with the
$(wildcard ...) function.
However, the $(wildcard ...) function is expanded at the moment the
rule is evaluated. And with per-package directory, at the time the
rule is evaluated, the global $(TARGET_DIR) is empty, so $(wildcard
...) will return nothing. It is indeed only after the call to
per-package-rsync that the TARGET_DIR will be populated.
This commit fixes that by moving away from $(wildcard ...) and use a
shell test instead, since we are anyway in big block of shell code.
With this, locales are properly purged again when
BR2_PER_PACKAGE_DIRECTORIES=y.

This provides generic functions for Qt5 qmake based packages. It will
make it possible to remove lots of redefinition of
QT5_xxx_{CONFIGURE|BUILD|INSTALL_STAGING}_CMDS. Additionally it
provides a generic target install method which will make most of the
package specific commands obsolete.
This is done by re-running the install step of the qmake generated
Makefile with the package build directory prepended (to the
staging/host path). Even though this does create lengthy pathes it
allows for easy separation of the staging files from the host destined
files by just omitting the resulting BUILD_DIR+HOST_DIR path from the
following rsync call to the real target folder. The cleanup of many
files we dont want in target is deferred to the target-finalize
step. In addition to what's being removed already, we also have to
cleanup some Qt5 specific files (prl) and the documentation directory.
This approach was chosen over copying all files recorded in the pkg-files-list
after some discussion which Thomas Petazzoni summed up:
"We don't yet use pkg-files-list really as part of the build
process anywhere, I feel a bit more comfortable at this point with what
Andreas is proposing."
Thanks to this infrastructure, it will be possible to get rid of the
many conditional install commands because qmake already takes care of
this when generating the Makefile install targets with the given or
autodetected configure options of each package.
However, custom install steps may have to remain in cases where a
particular Buildroot option has no corresponding setting in the
packages configuration options.

Several users of rolling-release distributions have been reporting on
IRC that Buildroot is broken now that they have switched to the newly
released make 4.3.
It turns out that the constructs we use to generated and include the
internal br2-external related fragments is no longer working with
make-4.3.
Indeed, an upstream bug report [0] seems to imply that it so far was
working by chance. There has been no further feedback, whether this is
really considered a fix for a previous ill-defined behaviour, or an
actual regression...
In the meantime, we add a workaround, suggested in that same bug report,
that fixes the issue for make 4.3, and that should not break on older
make versions either (verified on all relevant versions: from 3.81,
3.82, 4.0, 4.1, and 4.2).

The current solution used to collect the list of files installed by
packages does not work for top-level parallel build. Indeed, we rely
on a file created after the installation of the previous package to
build the list of files installed by the current package.
This works well when packages are built sequentially, but badly fails
when using top-level parallel build.
More specifically, top-level parallel build can fail with:
comm: /home/thomas/buildroot/output/build/.files-list-host.new: No such file or directory
Because that file has been removed concurrently by the build process
of another package.
This commit reworks the logic in a very straight-forward way. Before
the installation of each package, we store the list of files that are
already installed and store it in the package build directory. After
the installation of each package, we store again that list of files,
calculate the difference with the before file, and store that as the
list of files installed by that package, still in the package build
directory.
At the end of the build, in target-finalize we collect all the
collected information into the global package file lists, that
continue to be installed in the same location as before, with the same
name.
There are however some differences:
(1) The files are no longer ordered in build order, but by alphabetic
ordering of packages. Indeed, "build order" no longer makes any
sense in the context of top-level parallel build.
(2) Some files which were incorrectly tracked are no longer
tracked. For example, the toolchain package is a target package,
but it installs files in $(HOST_DIR). In the previous logic, the
files installed by the toolchain package in $(HOST_DIR) were
incorrectly affected to the next host package that was installed
after the toolchain package. With our new logic, those files are
no longer tracked at all. To fix this, we would have to change
the logic to scan HOST_DIR/TARGET_DIR/STAGING_DIR for all
installation steps, not just for the install-host, install-target
and install-staging steps respecitively. But the result was
already incorrect anyway, and therefore this should be fixed
separately.
Note that the check_bin_arch hook needs to be adjusted: it was using
the global package-file-list.txt file, but this file is now created
only at the very end of the build. So instead, we use the current
package .file-list.txt file to know which packages have been installed
by the current package in $(TARGET_DIR).

Create the staging symlink the same way as the host symlink. This means
using a make dependency rather than recreating it every time.
In coreutils versions below 8.27, re-creation of symbolic links was not
atomic. This means that there is a period in time where the existing link is
removed, before the new one is created. In coreutils 8.27 this was fixed,
see [1]. Note that CentOS 7 ships with coreutils 8.22.
In the following scenario, this is a problem:
- an application is compiled using the sysroot prepared by Buildroot and
links against Xenomai userspace libraries, but its build process is steered
from outside of Buildroot
- to know the correct flags, the application makefile uses the 'xeno-config'
file to request them, and passes DESTDIR=/buildroot/output/staging
- the xeno-config responds with flags based on the path
'/buildroot/output/staging/...'
- while the application build is ongoing, a 'make' happens in Buildroot,
causing the 'staging' symlink to be recreated (even though it already
existed)
- when exactly at this time, the application calls the compiler with -I
flags pointing to output/staging, the build fails with:
-I/buildroot/output/staging/usr/include/xenomai/mercury: Error: ^ is not a directory
-I/buildroot/output/staging/usr/include/xenomai: Error: ^ is not a directory
-I/buildroot/output/staging/usr/include/xenomai/xenomai: Error: ^ is not a directory
-I/buildroot/output/staging/usr/include/xenomai/psos: Error: ^ is not a directory
Failed: ** ^ *
Work around this problem by only creating the staging symlink once, similar
to how the host symlink (if any) is created.
See also commit d0f4f95e39 which changed the
way these symlinks are made. The reasoning in this commit is to move away
from the 'dirs' target.

The package instrumentation step 'step_pkg_size' is populating the files:
output/build/packages-file-list.txt
output/build/packages-file-list-staging.txt
output/build/packages-file-list-host.txt
by comparing the list of files before and after installation of a package,
with some clever tricks to detect changes to existing files etc.
As an optimization, instead of gathering this list before and after each
package, where the 'after-state' of one package is the same as the
'before-state' of the next package, only the 'after-state' is used and
is shared between packages.
This works fine, except at the end of the build, as explained next.
In the target-finalize step, many files will be touched. For example, files
like /etc/hosts, /etc/os-release, but also all object files that are
stripped, and all files touched by post-build scripts or created by rootfs
overlays. This means that the 'after-state' of the last package does not
reflect the actual situation after target-finalize is run.
For a single complete build this poses no problem. But, if one incrementally
rebuilds a package after the initial build, e.g. with 'make foo-rebuild',
then all changes that happened in target-finalize at the end of the initial
build (the 'after-state' of the last package built) will be detected as
changes caused by the rebuild of package foo. As a result, all these files
will incorrectly be treated as 'owned' by package foo.
Correct this situation by capturing a new state at the end of
target-finalize, so that the 'before-state' of an incremental build will be
correct.
Note: the reasoning above talks about packages-file-list.txt and
target-finalize, but also applies to
packages-file-list-staging.txt/staging-finalize and
packages-file-list-host.txt/host-finalize.

This commit implements the core of the move to per-package SDK and
target directories. The main idea is that instead of having a global
output/host and output/target in which all packages install files, we
switch to per-package host and target directories, that only contain
their explicit dependencies.
There are two main benefits:
- Packages will now see only the dependencies they explicitly list in
their <pkg>_DEPENDENCIES variable, and the recursive dependencies
thereof.
- We can support top-level parallel build properly, because a package
only "sees" its own host directory and target directory, isolated
from the build of other packages that can happen in parallel.
It works as follows:
- A new output/per-package/ directory is created, which will contain
one sub-directory per package, and inside it, a "host" directory
and a "target" directory:
output/per-package/busybox/target
output/per-package/busybox/host
output/per-package/host-fakeroot/target
output/per-package/host-fakeroot/host
This output/per-package/ directory is PER_PACKAGE_DIR.
- The global TARGET_DIR and HOST_DIR variable now automatically point
to the per-package directory when PKG is defined. So whenever a
package references $(HOST_DIR) or $(TARGET_DIR) in its build
process, it effectively references the per-package host/target
directories. Note that STAGING_DIR is a sub-dir of HOST_DIR, so it
is handled as well.
- Of course, packages have dependencies, so those dependencies must
be installed in the per-package host and target directories. To do
so, we simply rsync (using hard links to save space and time) the
host and target directories of the direct dependencies of the
package to the current package host and target directories.
We only need to take care of direct dependencies (and not
recursively all dependencies), because we accumulate into those
per-package host and target directories the files installed by the
dependencies. Note that this only works because we make the
assumption that one package does *not* overwrite files installed by
another package.
This is done for "extract dependencies" at the beginning of the
extract step, and for "normal dependencies" at the beginning of the
configure step.
This is basically enough to make per-package SDK and target work. The
only gotcha is that at the end of the build, output/target and
output/host are empty, which means that:
- The filesystem image creation code cannot work.
- We don't have a SDK to build code outside of Buildroot.
In order to fix this, this commit extends the target-finalize step so
that it starts by populating output/target and output/host by
rsync-ing into them the target and host directories of all packages
listed in the $(PACKAGES) variable. It is necessary to do this
sequentially in the target-finalize step and not in each
package. Doing it in package installation means that it can be done in
parallel. In that case, there is a chance that two rsyncs are creating
the same hardlink or directory at the same time, which makes one of
them fail.
This change to per-package directories has an impact on the RPATH
built into the host binaries, as those RPATH now point to various
per-package host directories, and no longer to the global host
directory. We do not try to rewrite such RPATHs during the build as
having such RPATHs is perfectly fine, but we still need to handle two
fallouts from this change:
- The check-host-rpath script, which verifies at the end of each
package installation that it has the appropriate RPATH, is modified
to understand that a RPATH to $(PER_PACKAGE_DIR)/<pkg>/host/lib is
a correct RPAT.
- The fix-rpath script, which mungles the RPATH mainly for the SDK
preparation, is modified to rewrite the RPATH to not point to
per-package directories. Indeed the patchelf --make-rpath-relative
call only works if the RPATH points to the ROOTDIR passed as
argument, and this ROOTDIR is the global host directory. Rewriting
the RPATH to not point to per-package host directories prior to
this is an easy solution to this issue.

Back a few years ago, when we were starting to think about top-level
parallel build, we were not sure how to deal with packages that
installed the same files, so we wanted to catch the situation to assess
how prevalent that was, before we decided what to do and how to address
it.
However, the trend nowadays is that packages will install in a
per-package target/ (and staging/ and host/), and the final directories
will be assembled in a reproducible (alphabetical) order, so if two
packages install the same file, the last one will win (as is currently
the case).
Besides, check-uniq-files reports loads of spurious errors when packages
get reinstalled (e.g. during development).
Finally, check-uniq-files is the only script called during the build,
that is written in python.
So, get rid of check-uniq-files.
