> Review sent - very nice work on this Yury.
Thanks a lot, Nick!
Highlights:
> * I concur with Stefan that we should have a full PyCoroutineMethods struct at the C level, with a "tp_as_coroutine" pointer to that replacing the current tp_reserved slot
Do you think that tp_as_async is a better name? (I explained my point of view in code review comments)
Also, do we need slots for __aenter__ and __aexit__? We don't have slots for regular context manager protocol, fwiw.
> * I also concur with Stefan about adding a Coroutine ABC
I will. We definitely need it.
> * PyType_FromSpec (and typeslots.h) will need updating once we agree on a slot structure (with my recommendation being "define C level slots for all of the new PEP 492 methods")
> * I found CO_COROUTINE/CO_NATIVE_COROUTINE confusing as a reader of the implementation, as they only told me how the objects were defined, rather than telling me why I should care. Based on what I gleaned of their intended purpose from reading the implementation, I suggest switching this to instead use CO_COROUTINE (set for all coroutines, regardless of how they were defined) and CO_ITERABLE_COROUTINE (set only for those coroutines that also support iteration), and adjusting the naming of other APIs accordingly.
I agree that CO_COROUTINE is something that we should use for 'async def' functions (instead of CO_NATIVE_COROUTINE). However, CO_ITERABLE_COROUTINE sounds a bit odd to me, as generator-based coroutines (at least in asyncio) aren't supposed to be iterated over. How about CO_GENBASED_COROUTINE flag?
> * I found the names of the WITH_CLEANUP_ENTER and WITH_CLEANUP_EXIT bytecodes misleading, as they don't refer to the corresponding context management phases - they're both related to the "exit" phase. WITH_CLEANUP_START and WITH_CLEANUP_FINISH should be clearer for readers (both of the implementation and of the disassembled bytecode).
Big +1. Your names are much better. |
