IO::Event

Provides low level cross-platform primitives for constructing event loops,
with support for select, kqueue, epoll and io_uring.

Motivation

The initial proof-of-concept Async was built on NIO4r. It was perfectly
acceptable and well tested in production, however being built on libev was a
little bit limiting. I wanted to directly built my fiber scheduler into the
fabric of the event loop, which is what this gem exposes - it is
specifically implemented to support building event loops beneath the fiber
scheduler interface, providing an efficient C implementation of all the core
operations.

devel/ruby-io-event: update to 1.10.0

1.10.0 (2025-03-12)

* IO::Event::Profiler is moved to dedicated gem: fiber-profiler.
* Perform runtime checks for native selectors to ensure they are supported
  in the current environment.  While compile-time checks determine
  availability, restrictions like seccomp and SELinux may still prevent them
  from working.

1.8.0 (2025-02-05)

Detecting fibers that are stalling the event loop.

A new (experimental) feature for detecting fiber stalls has been added.
This feature is disabled by default and can be enabled by setting the
IO_EVENT_SELECTOR_STALL_LOG_THRESHOLD to true or a floating point number
representing the threshold in seconds.

When enabled, the event loop will measure and profile user code when
resuming a fiber.  If the fiber takes too long to return back to the event
loop, the event loop will log a warning message with a profile of the
fiber's execution.

> cat test.rb
#!/usr/bin/env ruby

require_relative "lib/async"

Async do
	Fiber.blocking do
		sleep 1
	end
end

> IO_EVENT_SELECTOR_STALL_LOG_THRESHOLD=true bundle exec ./test.rb
Fiber stalled for 1.003 seconds
	/home/samuel/Developer/socketry/async/test.rb:6 in \ 
'#<Class:Fiber>#blocking' (1s)
		/home/samuel/Developer/socketry/async/test.rb:7 in 'Kernel#sleep' (1s)

There is a performance overhead to this feature, so it is recommended to
only enable it when debugging performance issues.
