Async scheduler / execution expired

[travisbell]

Hey @ioquatix,

I'm kind of just looking for some validation for a timeout error I am seeing:

/usr/local/bundle/gems/async-2.35.3/lib/async/scheduler.rb:247:in 'IO::Event::Selector::URing#transfer': execution expired (Faraday::TimeoutError)

I am trying to figure out what's really happening here... so there's a timeout value that is set as part of the Faraday adapter that is ultimately being used as the total time this request takes to return? What confuses me is that this ultimately times out with IO::Event::Selector::URing#transfer? Is that expected?

[ioquatix]

Yes, that looks correct. The timeout fires while the client is waiting for the response:

	from /usr/local/bundle/gems/async-http-0.94.2/lib/async/http/protocol/http2/response.rb:110:in 'Async::HTTP::Protocol::HTTP2::Response::Stream#wait'
	from /usr/local/bundle/gems/async-http-0.94.2/lib/async/http/protocol/http2/response.rb:155:in 'Async::HTTP::Protocol::HTTP2::Response#wait'

are the two key lines.

Ok, great. Thanks for the sanity check!
