ruby_timeout_safe

Ruby Timeout Safe

ruby-timeout-safe is a Ruby library that provides a safe and reliable timeout functionality for executing Ruby blocks. It uses Ruby's threading and monotonic time to ensure that timeouts are enforced even in the presence of blocking operations or long-running computations.

Features

• Defines a RubyTimeoutSafe module with a timeout method that executes a given Ruby block with a specified timeout duration.
• If the block execution exceeds the timeout, a TimeoutError exception is raised.
• Supports handling large timeout values.
• Raises an ArgumentError if a negative timeout value is provided.

Installation

Add this line to your application's Gemfile:

gem 'ruby_timeout_safe'

Usage:

require 'ruby_timeout_safe'

# Execute a block with a 2-second timeout
RubyTimeoutSafe.timeout(2) do
  # Your code here
  sleep 1 # This will not raise a timeout error
  # ...
end

# Handling a timeout error
begin
  RubyTimeoutSafe.timeout(1) do
    # Your code here
    sleep 3 # This will raise a TimeoutError
  end
rescue Timeout::Error => e
  puts "Execution timed out: #{e.message}"
end

Caveats

This implementation uses Ruby's built-in threading and monotonic time functions. While it is more compatible with different Ruby implementations and platforms than a C extension, it may still have limitations based on Ruby's threading model.
