This package replaces default implementation of asyncio in Python 3.6 with
implementation in Python 3.7. A contextvars library
from MagicStack is also
included to make sure the package functions well.
After installation, this package will replace the builtin implementation of
asyncio in Python 3.6. To use the builtin implementation, you have to
uninstall this package or add an environment variable USE_BUILTIN_ASYNCIO=1
to avoid loading the replacements.
As PyThreadState in Python 3.6 does not include an unique identifier,
we cannot cache it when calling get_running_loop. Hence the performance
of the library may be degraded comparing to the original module in Python 3.7.
The whole package is released under Apache License 2.0. Codes under asyncio
module is copied from Python 3.7 source which is released under PSF License
Agreement with minimal modifications. Codes in contextvars.py is copied from
MagicStack codes released under Apache License 2.0.
