Bumps async from 2.25.0 to 2.34.0.

Changelog

Sourced from async's changelog.

v2.34.0

Kernel::Barrier Convenience Interface

Starting multiple concurrent tasks and waiting for them to finish is a common pattern. This change introduces a small ergonomic helper, Barrier, defined in Kernel, that encapsulates this behavior: it creates an Async::Barrier, yields it to a block, waits for completion (using Sync to run a reactor if needed), and ensures remaining tasks are stopped on exit.

require 'async'
Barrier do |barrier|
3.times do |i|
barrier.async do |task|
sleep(rand * 0.1)  # Simulate work
puts "Task #{i} completed"
end
end
end
All tasks are guaranteed to complete or be stopped when the block exits.

If an exception is raised by a task, it will be propagated to the caller, and any remaining tasks will be stopped. The parent: parameter can be used to specify a parent task for the barrier, otherwise it will use the current task if available, or create a new reactor if not.

v2.33.0

• Introduce Async::Promise.fulfill for optional promise resolution.

v2.32.1

• Fix typo in documentation.

v2.32.0

• Introduce Queue#waiting_count and PriorityQueue#waiting_count. Generally for statistics/testing purposes only.

v2.31.0

• Introduce Async::Deadline for precise timeout management in compound operations.

v2.30.0

• Add timeout support to Async::Queue#dequeue and Async::Queue#pop methods.
• Add timeout support to Async::PriorityQueue#dequeue and Async::PriorityQueue#pop methods.
• Add closed? method to Async::PriorityQueue for full queue interface compatibility.
• Support non-blocking operations using timeout: 0 parameter.

v2.29.0

This release introduces thread-safety as a core concept of Async. Many core classes now have thread-safe guarantees, allowing them to be used safely across multiple threads.
