State passed into startup and shutdown handlers

[eprparadocs]

I have a number of applications that have particular "state" needed in the startup handlers. It would be great to get the state passed in.

isn't that what you're lookig for @eprparadocs : https://www.starlette.io/applications/#storing-state-on-the-app-instance

I tried that but something between the creation of the FASTapi() app variable, and the invocation of the startup caused the state to vanish. In fact what happens is that after the innovation of the on_start the state got wiped out, I traced it down to a rather interesting problem. When my code starts up it is running in PID x. and after the server.server() is executed the pid is different, and the 'app' is reinitialized (because the module has been reloaded). So the state is completely gone. I'm not exactly who's fault this is starlette or FASTapi. But it is absolutely repeatable and why I wrote the original entry. Chance

Found it! Turns out to be an issue in uvicorn! For some reason - haven't gotten there yet - app variable is re-initialized using the state. So either I have it wrong in my code (though it comes from a sample someone wrote for the documentation) or there is something else going on.

Now, it's possible with Lifespan State.
