Load an iseq object from binary format String object created by RubyVM::InstructionSequence.to_binary.

This loader does not have a verifier, so that loading broken/modified binary causes critical problem.

You should not load binary data provided by others. You should use binary data translated by yourself.

Creates a regular expression to match IPv4 addresses

Set the default value for the :argc_limit option.

See new(). The initial default value is 256.

Set the default value for the :id_conv option.

See new(). The initial default value is a DRbIdConv instance.

Check that a method is callable via dRuby.

obj is the object we want to invoke the method on. msg_id is the method name, as a Symbol.

If the method is an insecure method (see insecure_method?) a SecurityError is thrown. If the method is private or undefined, a NameError is thrown.

Example:

Foo::Bar += 1
   ^^^^^^^^

WARNING This method opens a serious security hole. Never use this method in production code.

Sets the output stream for debugging:

http = Net::HTTP.new(hostname)
File.open('t.tmp', 'w') do |file|
  http.set_debug_output(file)
  http.start
  http.get('/nosuch/1')
  http.finish
end
puts File.read('t.tmp')

Output:
