Problem with sanic>21.6

[rmk135]

Hey,

Thanks for the great library!

Seems like there is an error on sanic > 21.6. The failure I see looks like that:

ERROR    sanic.error:http_protocol.py:110 protocol.connection_task uncaught

The failure occurs all the time, but if you need an example, take a look at: https://github.com/ets-labs/python-dependency-injector/tree/master/examples/miniapps/sanic

Thanks, Roman

We have the same problem 😬

Created a fix here but would need some feedback

Created a fix here but would need some feedback

The events system was overhauled in https://github.com/sanic-org/sanic/pull/2160

So you'll need to also add

        await self.app._server_event("init", "before")
        # Trigger after_start events
        await self.app._server_event("init", "after")

after await self.app._startup()

This is a showstopper for me. This package is unusable without a fix for sanic 21 (working addition to changes)

    await self.app._startup()
    await self.app._server_event("init", "before", loop=self.loop)
    # Trigger after_start events
    await self.app._server_event("init", "after", loop=self.loop)

I've ported the fix from @wochinge to here https://github.com/yunstanford/pytest-sanic/pull/66 and added the changes you mentioned @autumnjolitz

Hi @melindaloubser1 , I managed to rederive the same fixes you made lol

Wasn't paying attention till Google's auth libraries made me upgrade and jesus christ wow the internal fiddling is awful

[evialevy]

Im having this issue with signals -> find_route func is None, when running a test REST call using pytest-sanic 19, sanic-testing Sanic version is 22.6.1 If Im trying to run with simply app.asgin_client.get(...) find_route is not None but im failing on sanic.exceptions.SanicException: Loop can only be retrieved after the app has started running. Not supported with create_server function

Can someone suggest a solution - im very blocked with Sanic version upgrade
