[New-bugs-announce] [issue18587] urllib raises exception with string in 'errno' attribute

[Denis]

New submission from Denis:

On 'connection refused' error urllib creates IOError with wrong arguents:
args ('socket error', error(<os-dependent-number>, 'Connection refused'))

It results to dirty hacks in Python code like
  'if e.errno == "socket error": ...'

instead of traditional

  'id e.errno == errno.ECONNREFUSED: ...'
