Description Doppler 2020-02-12 02:42:26 UTC
Full message:
/usr/lib/portage/python3.8/socks5-server.py:33: DeprecationWarning: "@coroutine" decorator is deprecated since Python 3.8, use "async def" instead
  def handle_proxy_conn(self, reader, writer):
/usr/lib/portage/python3.8/socks5-server.py:197: DeprecationWarning: "@coroutine" decorator is deprecated since Python 3.8, use "async def" instead
  def handle_proxied_conn(self, proxied_reader, writer, parent_task):


This is displayed every time any package is installed unless FEATURES='-network-sandbox' is set.
Without digging very deep into this, it appears that it should be relatively simple to use async/await instead of decorators/yield. Those features are Python 3.5+ only, but the only remaining pre-3.5 implementation usable on Portage should be 2.7, which is already past EOL.
Comment 1 Doppler 2020-03-01 22:03:57 UTC
Correction: It appears with FEATURES=distcc
