[issue3062] Turtle speed() function has no effect under Mac OS X

[David Kwast]

David Kwast <[EMAIL PROTECTED]> added the comment:

I wrote a small python program to test turtle speed in OSX. I tested
with trunk and py3k branch.

The string input works differently with 2.5, 2.6 and 3.0. The turtle is
slower in 2.5 and almost the same speed in 2.6 and 3.0.

Here are my test results:

david-kwasts-macbook:turtle davidkwast$ ../python_3k/python speedy.py 
0:00:04.640639
0:00:02.031436
david-kwasts-macbook:turtle davidkwast$ ../python_trunk/python speedy.py 
0:00:04.598181
0:00:02.048452
david-kwasts-macbook:turtle davidkwast$ python speedy.py 
(Python version < 2.6 don't support int in speed funtion)
0:00:18.343453

[issue1879] sqrt(-1) doesn't raise ValueError on OS X

[David Kwast]

David Kwast added the comment:

On OSX 10.5 this behavior is confirmed (Python2.5 and 2.6a). This fix 
appears to be a good fix for python 2.6a.
