gems: update async requirement from ~> 1.31.0 to >= 1.31, < 2.25

[dependabot]

Updates the requirements on async to permit the latest version.

Changelog

Sourced from async's changelog.

v2.24.0

• Ruby v3.1 support is dropped.
• Async::Wrapper which was previously deprecated, is now removed.

Flexible Timeouts

When {ruby Async::Scheduler#with_timeout} is invoked with a block, it can receive a {ruby Async::Timeout} instance. This allows you to adjust or cancel the timeout while the block is executing. This is useful for long-running tasks that may need to adjust their timeout based on external factors.

Async do
	Async::Scheduler.with_timeout(5) do |timeout|
		# Do some work that may take a while...
	if some_condition
		timeout.cancel! # Cancel the timeout
	else
		# Add 10 seconds to the current timeout:
		timeout.adjust(10)
	# Reduce the timeout by 10 seconds:
	timeout.adjust(-10)
	
	# Set the timeout to 10 seconds from now:
	timeout.duration = 10
	
	# Increase the current duration:
	timeout.duration += 10
end

end

end

v2.23.0

• Rename ASYNC_SCHEDULER_DEFAULT_WORKER_POOL to ASYNC_SCHEDULER_WORKER_POOL.

Fiber Stall Profiler

After several iterations of experimentation, we are officially introducing the fiber stall profiler, implemented using the optional fiber-profiler gem. This gem is not included by default, but can be added to your project:

$ bundle add fiber-profiler

After adding the gem, you can enable the fiber stall profiler by setting the FIBER_PROFILER_CAPTURE=true environment variable:

$ FIBER_PROFILER_CAPTURE=true bundle exec ruby -rasync -e 'Async{Fiber.blocking{sleep 0.1}}'
Fiber stalled for 0.105 seconds
