From: Peter Eszlari <[email protected]>
Meson is a fast and simple build system. Adoption started mainly in the
desktop space (Gnome, X11, Mesa) to replace autotools, but since then,
some low level projects (systemd, qemu) have switched to it too.
Since liburing is a rather small codebase, the difference in
speed and simplicity are not as huge as with other projects.
Nonetheless, there are still some advantages:
* It comes with some nice features (e.g. out-of-source builds),
that one would need to implement in shell otherwise.
* Other projects that use Meson could integrate liburing easily
into their build system by using Meson's subproject() functionality.
* Meson provides some useful editor/IDE integration,
e.g. by generating compile_commands.json for clangd.
* Distribution packagers are provided with a "standard" build system,
with well known options/features/behavior, that is actively developed.

* meson has builtin methods to check if the used compiler supports certain
types and their expected members. Therefore we don't need to check if code
using those types compiles. This makes the build file more readable.
Suggested-By: Nils Tonnätt <[email protected]>
* do not use -Wpedantic like the custom build system
* check if ucontext functions are available. See: b5f2347
* add explicit run_command check kwarg
The default will change in future meson versions causing possible
unexpected behavior.
And the awk command should not fail in the first place.
* set -DLIBURING_INTERNAL introduced in 8be8af4a
* include linux/openat2.h for struct open_how. See: 326ed975
* check if glibc provides struct statx. See: 44b12f5
* use -O3 as default. See: 7d1cce2
* update project CFLAGS. Remove -fomit-frame-pointer (de21479) and
add -fno-stack-protector (2de9832).

* Update the available tests.
* Check for -Warray-bound and -Wstringop-overflow and use them if available.
Include test/helper.c when building the test executables.
* Bump required meson version from 0.53 to 0.54 to use fs.stem.
* Simplify the meson test definition code by using a plain list of source
files instead of the complex list of lists.
Obtain the test name by stripping the file suffix from the test source
using the meson fs module.
* Link each test with the thread dependency similar to: 664bf78.
* Run tests sequentially to prevent dmesg log intermixing expected
by the test tooling.
Suggested-by: Eli Schwartz <[email protected]>
* Add a 'parallel' test suite to mirror make test-parallel.

`make -C test runtests`.
To execute the other test suites (running the tests in a loop or in
parallel) run: `meson test --suite=loop` or `meson test --suite=parallel`.

Introduce a new meson option 'nolibc'.
Include the headers in src/arch when building liburing.
Build the src/syscall.c as seperate library for the tests when building
without libc.

The 'raw' test suite runs each compiled test without the runtest*.sh
wrapper scripts.
This is useful to debug tests using meson's gdb support.
To debug a test in gdb run `meson test -C build --suite=raw <testname>_raw`

Use an array of sources instead of declaring each example individually.
Add examples introduced by Pavel and Dylan in 82001392, c1d15e78 and 61d472b.

To me this diffstat tells me that this patch series adds a lot of
complexity instead of removing complexity. That leaves me wondering what
the advantages of this patch series are?

That's because Jens wants to keep both build systems in the repository.

This is what the diffstat could look like if we would remove the old build system.
> That leaves me wondering what the advantages of this patch series are?
The most notable advantages of having a meson-based build system are highlighted
in the cover mail.
For me the by far most important feature and why I maintained the initial meson
code from 2021 is the interoperability with other meson-based projects.
Everything needed to consume liburing is to have a wrap file for liburing in your
subprojects directory and use it in your meson build logic.
subprojects/liburing.wrap:
[wrap-git]
url = https://git.kernel.dk/liburing
revision = master
And use the following lines in your meson code:
liburing_proj = subproject('emper')
liburing_dep = liburing_proj/get_variable('uring')
# somehow use the dependency object

To point this out explicitly:
old Makefile-based build system: 947 LoC
new Meson-based build system: 609 LoC
That is a significant reduction in build-system complexity, while the
new Meson-based build system has more features, e.g., out-of-source
builds and a sensible test framework. For further features, see the
cover-letter of this patch set.
