[New-bugs-announce] [issue6218] Make io.BytesIO and io.StringIO picklable.

[Alexandre Vassalotti]

New submission from Alexandre Vassalotti <alexandre at peadrop.com>:

Here is a patch to add pickling support to io.BytesIO and io.StringIO.
Although they are non-trivial, the additions were made with a fair
amount of care (and love!) and thus I believe they could be included in
3.1. 

Furthermore, the improved test-suite uncovered a number of bugs in the
implementation of io.StringIO. So the patch also fixes:

  * fixes a memory-leak in stringio_dealloc; 
  * disallows bytes-like object from being used as the newline
    argument of StringIO;
  * and changes the exception raised by StringIO.__init__ to a
    TypeError when initial_value is not a str.
