Describe the bug

When running Sanic 25.12.0 on Python 3.14, the following deprecation warnings are still emitted:

  /usr/local/lib/python3.14/site-packages/sanic/server/loop.py:46: DeprecationWarning: 'asyncio.get_event_loop_policy' is deprecated and slated for removal in Python 3.16
    if not isinstance(asyncio.get_event_loop_policy(), uvloop.EventLoopPolicy):
  /usr/local/lib/python3.14/site-packages/sanic/server/loop.py:47: DeprecationWarning: 'asyncio.set_event_loop_policy' is deprecated and slated for removal in Python 3.16
    asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())
  /usr/local/lib/python3.14/site-packages/sanic/server/runners.py:174: DeprecationWarning: 'asyncio.iscoroutinefunction' is deprecated and slated for removal in Python 3.16; use inspect.iscoroutinefunction() instead
    loop.add_signal_handler(

PR #3115 addressed some Python 3.14 issues but these specific deprecations in loop.py and runners.py were not fixed.

Code snippet

from sanic import Sanic
  from sanic.response import text
  from sanic.worker.loader import AppLoader

  def create_app() -> Sanic:
      app = Sanic("test-app")

      @app.get("/health")
      def health(request):
          return text("OK")

      return app

  def main():
      loader = AppLoader(factory=create_app)
      app = loader.load()
      app.prepare(host="0.0.0.0", port=8080)
      Sanic.serve(primary=app, app_loader=loader)

  if __name__ == "__main__":
      main()

Expected Behavior

No deprecation warnings should be emitted when running on Python 3.14.

How do you run Sanic?

As a script (app.run or Sanic.serve)

Operating System
