Buildbots didn't get launched apparently but that's good as we're modifying the code. Let's wait until everytihng is stable and we'll launch the buildbots again

I forgot but what was the decision about ctypes?

@picnixz, are you about this suggestion:#121249 (comment)?

Patch is here:#121249 (comment). I think it's much less urgent, as for the ctypes module - support can't be available unconditionally.

PS: Not sure why bots aren't started. Perhaps, this label should be added by core dev.

Ok! I actually wondered about the fate of ctypes because I wondered whether we still needed the_complex.h header.

I don't remember so? but maybe it is.. anyway, I'll add the label once you've confirmed whether the previous blurb needs an update.

I may be wrong, but I still believe that ctypes support for complex can be implemented by relying exclusively on what the FFI library (and the C compiler used to build that library) supports, and not what the C compiler used to build CPython supports. When all this work settles and everything gets merged, I can try to prove my claim with a patch.

Feel free to do this even right now. But you should be able to prove that my concern is invalid.

The thing is, I'm still not sure what's your concern, I don't understand what exactly you meant by "annex G support still required from system". I actually agree with such claim, as long a "system" mean the C compiler used to build FFI, and the C compiler used to build a shared lib thatctypes call into, but NOT the C compiler used to build CPython and ctypes.
For example, I claim that the FFI library and some third-party library that accepts/returns complex numbers can be built with a modern GCC version, thus both sides have annex G support. But then you can build CPython/ctypes with some experimental in-development compiler that does not implement annex G support just yet, and things should still work fine, ctypes is passing complex values back and forth via the FFI library, and not the C compiler used to build CPython/ctypes. If this claim is not correct, then for sure I have a misunderstanding of how the FFI library implementation works, and in such case, I apologize for all the noise.

I tried to explain it twice:#121249 (comment) and#121249 (comment). Sorry, it's my best.

ctypes is passing complex values back and forth via the FFI library

The only way to pass it on ctypes side will be a two-element array then. I'm not sure if this will work, as it's not how complexes passed to a function.

@skirpichev I'm so sorry... but I didn't see that the entire changelog contains all previous alphas as well.. so, if we were to remove the NEWS we'll have a missing entry in the changelog page... So just restore the 3.14.0a1.rst file to what it has been but keep the new one for the beta section. You can say that previously it was conditioned though.

Results will be shown at:

https://buildbot.python.org/all/#/grid?branch=refs%2Fpull%2F132864%2Fmerge

If you want to schedule another build, you need to add the🔨 test-with-buildbots label again.

I see no failures, related to the pr.
