[New-bugs-announce] [issue7348] StringIO.StringIO.readline(-1) returns the wrong result compared to other file-like objects

[Jean-Paul Calderone]

New submission from Jean-Paul Calderone <exarkun at divmod.com>:

cStringIO and file both accept -1 to readline to mean the same thing as
not passing any argument at all.  StringIO, on the other hand, gets
totally confused:

  >>> from StringIO import StringIO
  >>> StringIO('a\nb\nfoo').readline(-1)
  'a\nb\nfo'
  >>>
