Bug #11179

Inconsistent Addrinfo parsing a port number

Added by ibenza (Shin'ya Ueoka) over 4 years ago. Updated over 4 years ago.

Status:
Third Party's Issue
Priority:
Normal
Assignee:

Target version:

ruby -v:
ruby 2.3.0dev (2015-05-25 trunk 50637) [x86_64-linux]
[ruby-core:69353]

Description

In the case of the following code, ip_port returns 34464 because the number 99999 is cast as short int.
Is the result expected?

require 'socket'
Addrinfo.tcp('', 99999).ip_port    # => 34463

Even if the above behavior is correct, ip_port should return 65535 in the following code. But actually, Addrinfo raises an exception because -1 is parsed as service name. This behavior is inconsistent with the above.

require 'socket'
Addrinfo.tcp('', -1).ip_port     # => Servname not supported for ai_socktype (SocketError)

  • Subject changed from Addrinfo parsing a port number to Inconsistent Addrinfo parsing a port number

Updated by akr (Akira Tanaka) over 4 years ago

  • Status changed from Open to Third Party's Issue

The behavior is inherited from getaddrinfo() function in libc.
So it is difficult to fix the problem in Ruby.
