[New-bugs-announce] [issue16012] pyexpat: Argument for UseForeignDTD should be optional

New submission from Erich Seifert:

It seems the recent changes to Modules/pyexpat.c made the boolean 'flag' for UseForeignDTD mandatory although it was optional in previous Python releases.

According to the docs the usage is UseForeignDTD([flag]), but calling UseForeignDTD without arguments leads to an error::

  >>> from xml.parsers import expat
  >>> parser = expat.ParserCreate('utf8')
  >>> parser.UseForeignDTD()
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  TypeError: UseForeignDTD() takes exactly 1 argument (0 given)

This was tested with version bfdf366a779a from hg repository.
