1.9.4: pep517 based build does not build DSO modul about yarl

[webknjaz]

I don't know what DSO is, but packaging works as expected. Refer to the changelog for the downstream notes.

DSO -> Dynamic Shared Object.

but packaging works as expected. Refer to the changelog for the downstream notes.

That is odd that now is necessary to force to build DSO. IMO it should be default behaviour.
After add --config-setting=pure-python=true --config-setting=with-cython-tracing=true to build params it still does not work

+ /usr/bin/python3 -sBm build -w --no-isolation --config-setting=pure-python=true --config-setting=with-cython-tracing=true

In whole source tree I don't see any .c files generated.

FYI: I'm using cython 3.0.5.

The tree is not modified in-place anymore. The compiled C-extensions are in the wheel. You can read it in your own log.

It does. You requested no extensions — you got no extensions, only pure Python.

build does not perform by DEFAULT in-place build. All is done in build/.
And again. After all there is no generated .c file(s) so it is not possible to compile anything.

What kind of extension?
