Research direction

Start by reproducing the import on Debian Bullseye with PyPy 3.9 and uvloop 0.17.0, then inspect uvloop/init.py and the imported loop.pypy39-pp73-x86_64-linux-gnu.so associated with the undefined PyContext_CopyCurrent symbol. Done means uvloop imports successfully under PyPy and the relevant import behavior is covered by an appropriate regression test.

Written by the indexing model from the issue text.

Description

uvloop version: 0.17.0
Python version: pypy3.9
Platform: Debian Bullseye
Can you reproduce the bug with PYTHONASYNCIODEBUG in env?: Yes
Does uvloop behave differently from vanilla asyncio? How?: Vanilla asyncio does not create this error

uvloop fails to import with the following traceback

  File "/var/gpob/GB.py", line 36, in <module>
    import uvloop
  File "/usr/lib/pypy3.9/site-packages/uvloop/__init__.py", line 7, in <module>
    from .loop import Loop as __BaseLoop  # NOQA
ImportError: /usr/lib/pypy3.9/site-packages/uvloop/loop.pypy39-pp73-x86_64-linux-gnu.so: undefined symbol: PyContext_CopyCurrent```
