This adds back sd-boot builds by using meson compile targets directly.
We can do this now, because userspace binaries use the special
dependency that allows us to easily separate flags, so that we don't
pass anything to EFI builds that shouldn't be passed.
Additionally, we pass a bunch of flags to hopefully disable/override any
distro provided flags that should not be used for EFI binaries.
Fixes: #12275
This drops all mentions of gnu-efi and its manual build machinery. A
future commit will bring bootloader builds back. A new bootloader meson
option is now used to control whether to build sd-boot and its userspace
tooling.
In 6abe882bae the renderer was made to
unconditionally append a newline to output. This works, but is ugly. A nicer
solution is to tell jinja2 to not strip the newline in the first place, via
keep_trailing_newline=True. It seems that the result is unchanged because all
our source files have exactly one trailing newline.
Also, enable lstrip_blocks=True. This would cause whitespace on the line before
an {%if block to be automatically stripped. It seems reasonable to enable that
if trim_blocks=True.
Overall, no change is expected, though I didn't test combinations of
configurations, so there might be a change in some cases. But now the rules of
rendering are more logical, e.g. we should be able to indent nested conditional
statements without getting unexpected whitespace in the output.
(The one case that is left unchanged is '< <(subcommand)'.)
This way, the style with no gap was already dominant. This way, the reader
immediately knows that ' < ' is a comparison operator and ' << ' is a shift.
In a few cases, replace custom EOF replacement by just EOF. There is no point
in using someting like "_EOL" unless "EOF" appears in the text.
Since the files with generated directives are now automatically
generated during build, they're now under the respective build directory
which the current oss-fuzz CI script didn't account for.
Follow-up to: #24958Resolves: #25859
We generate a "version string" that is reported by various tools. This patch
changes this version string to use the characters specified for the version
string in the Boot Loader Specification. We start using the special characters
we have in the spec for this exact purpose and thus fix version comparisons.
We also stop using '+' which is not part of the allowed charset and is used for
boot attempt counting and should not be part of the version string.
The version string is (among other places) used in sd-boot and the comparison
result is used by 'bootctl update' to decide whether to install a new binary.
Before, because 'nn-rc1' compares higher than 'nn', we would refuse to upgrade
pre-release versions.
The boot loader is the primary motivation. I'm not aware of programatic version
comparisons in other places, but it makes sense to use the same versions string
everywhere.
(This patch effectively only matters for non-distro builds, because distro
builds presumably use -Dversion-tag to set something meaningful. Ideally, those
version strings are compatible with our version strings, but this is outside of
our control.)
The lists of directives for fuzzer tests are maintained manually in the
repo. There is a tools/check-directives.sh script that runs during test
phase and reports stale directive lists.
Let's rework the script into a generator so that these directive files
are created on-the-flight and needn't be updated whenever a unit file
directives change. The scripts is rewritten in Python to get rid of gawk
dependency and each generated file is a separate meson target so that
incremental builds refresh what is just necessary (and parallelize
(negligible)).
Note: test/fuzz/fuzz-unit-file/directives-all.slice is kept since there
is not automated way to generate it (it is not covered by the check
script neither).
We're already using C.UTF-8 as the default locale for nspawn. Let's
make the same change for the default-locale option instead of deciding
what to use based on the locale used by the host system. Users can
still override the locale using the default-locale option if needed.
No need to involve a trivial shell script for this.
We could call the compiler directly, but test() expects arguments
to be passed separately and cc.cmd_array() can contain arguments
itself. Using env is easier than manually slicing the array because
meson has no builtins for that.
Bash will generate a very nice message for us:
/tmp/ff.sh: line 1: SOMEVAR: parameter null or not set
Let's save some keystrokes by not replacing this with our own inferior
messages.
