Any updates on this issue is highly appreciated.

Still getting this issue.

Any updates on this one? Would also like to use uvloop via pypy37

Same issue for me, just installed uvloop on pypy:3.8-7.3.7-bullseye, I got the following error

File "/opt/pypy/lib/pypy3.8/site-packages/uvloop/__init__.py", line 7, in <module>
    from .loop import Loop as __BaseLoop  # NOQA
ImportError: /opt/pypy/lib/pypy3.8/site-packages/uvloop/loop.pypy38-pp73-x86_64-linux-gnu.so: undefined symbol: PyContext_CopyCurrent

It happened on aarch64 linux platform(hardware is NanoPi NEO3) too. I test it by using

• pypy3.8 Python 3.8.13 (4b1ae7a563b2c8614ef6faeaa60e749d10398c08, Apr 12 2022, 23:28:48) [PyPy 7.3.10-alpha0 with GCC 10.2.1 20210130 (Red Hat 10.2.1-11)]

• pypy3.9

to import uvloop, and it says:

>>>> import uvloop
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/pi/pyxy/.env/lib/pypy3.8/site-packages/uvloop/__init__.py", line 7, in <module>

It seems like pypy missing some Cfunction.

In PyPy, the _contextvars module is pure python. In order to support it from C, PyPy needs to wrap and expose all the C interfaces. Currently PyPy exposes only PyContextVar_New, PyContextVar_Set, PyContextVar_Get. Using uvloop on PyPy is probably a bit of a foot gun, since the calls back and forth across the c emulation layer will be slower than using the pure python alternatives.

I would be curious to see how PyPy running asyncio performs in the performance benchmark in the uvloop README.

Am curious if anyone tried this
