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.

Currently, we group packages that contribute less then 1%, into the
"Other" category.
However, in some cases, there can be a lot of very comparatively small
packages, and they may not exceed this limit, and so only the "Others"
category would be displayed, which is not nice.
Conversely, if there are a lot of packages, most of which only so
slightly exceeding this limit, then we get all of them in the graph,
which is not nice either.
Add a way for the developers to pass a different cut-off limit. As for
the dependency graph which has BR2_GRAPH_DEPS_OPTS, add the environment
variable BR2_GRAPH_SIZE_OPTS to carry those extra option (in preparation
for more to come, later).

But now, we are on the verge of generating more files on the kconfig

And even better yet, we can generate both the Makefile-side and

Currently, that file is generated rather late in the configuration

We're soon to generate that file much earlier, at a point where
BUILD_DIR is not yet known, so we have two options:
1- declare BUILD_DIR earlier;
2- generate the file in an already-known location.
We go with the second solution, as we're already generating a
br2-external related file in BASE_DIR, so we can as well generate all
br2-external files in the same place.

Introduce a new per-package (and per-filesystem) foo-show-info rule,
that otputs a per-entity valid JSON blob.
Note that calling it for multiple packages and.or filesystems at once

However, jq is able to absorb this, with its slurping ability, which

Users are increasingly trying to extract information about packages. For
example, they might need to get the list of URIs, or the dependencies of
a package.
Although we do have a bunch of rules to generate some of that, this is
done in ad-hoc way, with most of the output formats just ad-hoc, raw,
unformatted blurbs, mostly internal data dumped as-is.
Introduce a new rule, show-info, that provides a properly formatted
output of all the meta-information about packages: name, type, version,
licenses, dependencies...
We choose to use JSON as the output format, because it is pretty
versatile, has parsers in virtually all languages, has tools to parse
from the shell (jq). It also closely matches Python data structure,
which makes it easy to use with our own internal tools as well. Finally,
JSON being a key-value store, allows for easy expanding the output
without requiring existing consumers to be updated; new, unknown keys
are simply ignored by those (as long as they are true JSON parsers).
The complex part of this change was the conditional output of parts of
the data: virtual packages have no source, version, license or
downloads, unlike non-virtual packages. Same goes for filesystems. We
use a wrapper macro, show-info, that de-multiplexes unto either the
package-related- or filesystem-related macros, and for packages, we also
use a detailed macro for non-virtual packages.
It is non-trivial to properly output correct JSON blurbs, especially
when trying to output an array of objects, like so, where the last item
shall not be followed by a comma: [ { ... }, { ... } ]
So, we use a trick (as sugegsted by Arnout), to $(subst) any pair of
",}" or ", }" or ",]" or ", ]" with only the respective closing symbol,
"}" or "]".
The whole stuff is $(strip)ed to make it a somewhat-minified JSON blurb
that fits on a single line with all spaces squashed (but still with
spaces, as it is not possible to differentiate spaces between JSON
elements from spaces inside JSON strings).

Currently, when we need to build the full dependency graph, we call make
to show the list of packages (make show-targets), and then call it again
and again iteratively while it returns new packages.
Since calling make will parse the whole set of our Makefiles, this takes
quite a bit of time (~4s each here), and the total can get pretty long.
However, make being make, already builds the whole dependency tree
information, so we can just ask for it.
Add a new top-level rule 'show-dependency-tree' that displays the whole
set of dependencies for all packages. For each package, its name, type
and version is displayed, then all the direct, first-level dependencies
are dumped. We choose a format that is not unlike the dot-graph format,
because it is both easy to read as a human, and easy to parse as a
machine:
foo: target 1.2.3
foo -> bar host-meh
bar: target virtual
bar -> buz
buz: target 2.3.4
buz ->
host-meh: host virtual
host-meh -> host-bleark
host-bleark: host 3.4.5
host-bleark ->
rootfs-meh: host
rootfs-meh -> host-bleark
To be noted: rootfs are currently reported as if they were 'host'
packages, to stay aligned with how graph-depends currently treats them.
Ideally, graph-depends could be enhanced to recognise them separately,
but that is another story.
For just plain defconfig, which is about the smallest config we can have
with an internal toolchain, we already have a seven-fold improvement
(with the graph-depends rule modified to not run the pdf generation, to
be able to just compare the tree generation):
$ time make graph-depends
real 0m27.344s
$ time make show-dependency-tree
real 0m3.848s
>From defconfig, C++, wchar, locales, ssp, and allyespackageconfig,
tweaked for even more packages (qt5 not qt4, luajit to avoid multi
providers, etc...), the timings are (graph-depends still modified to
not generate the pdf):
$ time make graph-depends
real 1m56.459s
$ time make show-dependency-tree
real 0m5.748s
There. I don't think those numbers need any explanation whatsoever;
they do speak on their own. OK, for maths sake, the ratio is about
twenty-fold. So, "yeah", I guess... ;-)

Using 'make printvars' for printing all variables is not very useful.
E.g. all macros will output some bogus value. In addition, the same can
be achieved with 'make -p'.
We can simply remove the condition on $(VARS). If VARS is not set, the
filter expression will be empty which matches nothing, so nothing is
printed.
Note that the old behaviour can still be achieved with:
make printvars VARS=%
Update the 'make help' text to match the new behaviour.

Since commit 0db34529f4 we use rsync with the --keep-dirlinks option to
prevent overlays from accidentally overwriding /{usr,bin,sbin,lib} links
when BR2_ROOTFS_MERGED_USR option is enabled. Unfortunately this also
prevents replacing a symlink by a directory on purpose (e.g. /var/log,
to persist system logs).
Steps to reproduce:
- enable BR2_ROOTFS_MERGED_USR and BR2_PACKAGE_SKELETON_INIT_SYSV
- mkdir some_path/rootfs-overlay/var/log
- enable BR2_ROOTFS_OVERLAY="some_path/rootfs-overlay"
- run 'make'
- 'target/var/log' is still a symlink to '../tmp', not a directory
The --keep-dirlinks option can be dropped, since we run sanity checks
on overlays. Now the rsync invocation is identical to the SYSTEM_RSYNC
logic we have in system/system.mk, so use that variable.

The current transform changes any '.' at the start of a filename to
$(BR2_SDK_PREFIX). This also applies to the target of a symlink, when
it is relative.
We thus might end up with something like:
$(BR2_SDK_PREFIX)/bin/aarch64-linux-gnu-ar ->
$(BR2_SDK_PREFIX)./opt/ext-toolchain/bin/aarch64-linux-gnu-ar
when it should be:
$(BR2_SDK_PREFIX)/bin/aarch64-linux-gnu-ar ->
../opt/ext-toolchain/bin/aarch64-linux-gnu-ar
We fix that by making sure we always remove a known prefix, i.e. we
remove the path to host dir. The obvious solution would be to cd into
$(HOST_DIR)/.. , then tar ./host/ and finally use a --transfrom pattern
as 's,^\./$(notdir $(HOST_DIR)),$(BR2_SDK_PREFIX)'.
Since $(HOST_DIR) can point to a user-supplied location, we don't know
very well how the pattern may patch.
Instead, we cd into / and tar the full path to $(HOST_DIR).
Since tar removes any leading '/', it would spurr a warning message,
which is annoying. So we explicitly remove the leading '/' from
$(HOST_DIR) when we tar it.
Finally, we transform all filenames to replace a leading $(HOST_DIR)
(without a leading /) to the prefix to use.

is useful to test simple packages which do not have "complex" dependencies.
However; if a developer uses test-pkg -p ${package_name} to check their package,
the package may pass all the checks, but would have otherwise failed with a
simple "make" because the developer may have failed to add a select line in
packages config file, even if there is a new dependency in the packages
Makefile.

GitLab has severe limitations imposed to triggers.
Using a variable in a regexp is not allowed:
| only:
| - /-$CI_JOB_NAME$/
| - /-\$CI_JOB_NAME$/
| - /-%CI_JOB_NAME%$/
Using the key 'variables' always lead to an AND with 'refs', so:
| only:
| refs:
| - branches
| - tags
| variables:
| - $CI_JOB_NAME == $CI_COMMIT_REF_NAME
would make the push of a tag not to trigger all jobs anymore.
Inheritance is used only for the second level of keys, so:
|.runtime_test: &runtime_test
| only:
| - tags
|tests.package.test_python_txaio.TestPythonPy2Txaio:
| <<: *runtime_test
| only:
| - /-TestPythonPy2Txaio$/
would override the entire key 'only', making the push of a tag not to
trigger all jobs anymore.
So, in order to have a trigger per job and still allow the push of a tag
to trigger all jobs (all this in a follow up patch), the regexp for each
job must be hardcoded in the .gitlab-ci.yml and also the inherited
values for key 'only' must be repeated for every job.
This is not a big issue, .gitlab-ci.yml is already automatically
generated from a template and there will be no need to hand-editing it
when jobs are added or removed.
Since the logic to generate the yaml file from the template will become
more complex, move the commands from the main Makefile to a script.
Using Python or other advanced scripting language for that script would
be the most versatile solution, but that would bring another dependency
on the host machine, pyyaml if Python is used. So every developer that
needs to run 'make .gitlab-ci.yml' and also the docker image used in the
GitLab pipelines would need to have pyyaml pre-installed.
Instead of adding the mentioned dependency, keep using a bash script.
While moving the commands to the script:
- mimic the behavior of the previous make target and fail on any
command that fails, by using 'set -e';
- break the original lines in one command per line, making the diff for
any patch to be applied to this file to look nicer;
- keep the script as simple as possible, without functions, just a
script that executes from the top to bottom;
- do not perform validations on the input parameters, any command that
fails already makes the script to fail;
- do not add an usage message, the script is not intended to be called
directly.
This patch does not change functionality.
