blueprint-compiler: update to 0.12.0

[v1993]

Any idea what's going on with MacOS/Alpine failures? I can't seem to find any useful error messages in logs.

Apparently no tests were ran, Cf. unittest documentation:

The testRunner argument can either be a test runner class or an already created instance of it. By default main calls sys.exit() with an exit code indicating success (0) or failure (1) of the tests run. An exit code of 5 indicates that no tests were run or skipped.

See https://github.com/python/cpython/issues/113661.

Anyway, no tests are discovered is the underlying issue, because of this:

test('tests', py, args: ['-m', 'unittest'], workdir: meson.source_root())

And meson.source_root() will return the parent project source root:

meson.source_root()

Returns a string with the absolute path to the source root directory.

This function will return the source root of the parent project if called from a subproject, which is usually not what you want. Try using meson.current_source_dir() or meson.project_source_root(). In the rare cases where the root of the main project is needed, use meson.global_source_root() that has the same behaviour but with a more explicit name.

So no tests are discovered.

Once the call is patched to use meson.project_source_root(), the tests fail as expected because of missing dependencies:

Install py3-gobject3

[benoit-pierre]

That still does not fix the underlying problem: https://gitlab.gnome.org/jwestman/blueprint-compiler/-/merge_requests/192.

Yeah. Unfortunate.
