I would think this needs to be a Generator, but maybe not?

This is true for a variety of spots we use yield.

(Or maybe I can significantly simplify type hints in other spots!)

I opted for using the most basic type that callers want, to minimize assumptions, rather than documenting the concrete return type.

All Generators are Iterators (and all Iterators are Iterable), and in this case this seems cleaner than saying a Generator[Metric, None, None].

Curious why this is object and not Any?

It's to make mypy complain if we ever try to use the return values of the callbacks.

Everything is assignable to object, but not the other way around, whereas Any is assignable to everything without any checks.

object is the supertype of everything is what I think you're saying, so we'd get shouted at if we tried to do x: int = (something returning object) whereas Any is entirely untyped & unchecked.

I think this makes sense.

Does this mean we should generally prefer object over Any?

I haven't a clue. I imagine it's on a case by case basis. Any is certainly a last resort for me, since it's equivalent to not annotating types at all.

I think this should work, but maybe not? This makes me a bit nervous that we're not mentioning this returns a Deferred.

Not sure what to do about this. I updated the docstring above to call the change of return type out.

We can either annotate the return type correctly and lose the types of the arguments for the decorated function,
or annotate the return type incorrectly and preserve the types of the arguments.

I feel kind of bad about lying but appreciate the dilemma. :/

I'm not really sure what's best, though. Is lying going to cause type errors for users of the function?

I would probably make the docstring louder about the return type being a lie, though.

I tried to improve the docstring further

I think it's fine as - is.

question though, what happens if you bound F to return an Awaitable?

F = TypeVar("F", bound=Callable[..., Awaitable])

(or something similar?)

I think it's fine as - is.

to be clear: I'm saying I'm happy with the PR as it stands.

question though, what happens if you bound F to return an Awaitable?
F = TypeVar("F", bound=Callable[..., Awaitable])

Ooh. mypy throws up 3 errors which all look trivial to fix:

synapse/util/caches/expiringcache.py:86: error: Argument 2 to "run_as_background_process" has incompatible type "Callable[[], None]"; expected "Callable[..., Awaitable[Any]]" [arg-type] synapse/app/_base.py:404: error: Value of type variable "F" of function cannot be "Callable[[VarArg(Any), KwArg(Any)], None]" [type-var] synapse/handlers/typing.py:92: error: Value of type variable "F" of function cannot be "Callable[[FollowerTypingHandler], None]" [type-var]

So it sounds like the cleanest thing to do is to restrict run_as_background_process to only accept Awaitable-returning functions and drop the whole maybe_awaitable thing. I'll make the change when I find some time.

I've gotten rid of the maybe_awaitable.

What's being ignored here?

It's to suppress error: Overloaded function signatures 1 and 2 overlap with incompatible return types [misc]. I shall add a comment

I initially tried a Union but ran into a bug/deficiency in mypy where it couldn't figure out what R was at every call site.
#10847 (comment)

If you have a tracking link to e.g. a mypy issue or something of the sort, could be good. (and maybe add a remark that you tried Union[Awaitable[R], R] or whatever, to save someone for thinking 'ha! I can see how to do that one!' and falling into the same pit)

I'm a bit sad Union[Awaitable[R], R] wouldn't have done the trick though, not your fault though

I tried to improve the comments further

I wonder if updating mypy in #11006 will have changed this situation at all?

Good shout! I gave it another go and mypy is still unhappy without the overloads (version 0.910?)

Shame. Worth a try!

This all seems to make sense. I'm a little bit concerned about the lie and would probably want to ask someone else on the team about that ...

+# Placeholder for `InFlightGauge._metrics_class`, which is created dynamically
+_MetricsEntry = Any


is this common practice in our code?

Is it possible/useful to create a Protocol for it (if we have no other choice)?

Right now, Any doesn't tell mypy (or me, or my IDE) a whole lot, though I do appreciate that you've taken the time to common it out into a common label :).

ah I see the fields are created dynamically. Makes sense, even if a bit sad.

I'm taking a look at adding more typing to synapse.utils and got stuck on annotating metrics here. I think it should be one of these dynamically-created types but can't annotate it meaningfully.

So +1 to any other smart approaches!

Python typings are really frustrating. The equivalent in typescript would be something like: this

Perhaps we can add a type parameter to InFlightGauge and make the calling code provide an appropriate Protocol?

Ok. InFlightGauge now takes a type parameter, so now those callbacks can have proper type annotations.
mypy forced me to annotate in_flight in synapse/util/metrics.py (sorry!).

Two caveats:

mypy won't allow the type parameter to be constrained to a Protocol

there's no check that the names passed to the InFlightGauge constructor match the attributes in the protocol

Thanks for pointing this out to me! I didn't realise I was holding it up.

I think the only thing on my mind was #10847 (comment) really — if other people are happy with an innocent lie, then I'm happy to roll it through (and it sounds like, bear in mind that we can one day use ParamSpec?)

No problem at all, but curious if this needed to be Optional[R] — I naïvely expect it would be fine to let it be R since R is variable.

It won't matter anyway since the return position of a Callable is contravariant (fn(...) -> R is-a fn(...) -> Optional[R]), and this function always returns Optional[R] regardless because of the error handling.

You're right, it ought to be Awaitable[R]

mypy gets unhappy elsewhere if I change it:
