First, I'd suggest checking to see whether this has been fixed in a
later version of Python. Or that the Python developers are at least
aware of it. Are you using the version from python.org?
If you can't get a correctly-functioning version of Python, I'd
suggest using a wrapper rather than writing the loop out repeatedly,
e.g.:
def fixed(func, *args, **kwargs):
while True:
try:
return func(*args, **kwargs)
except IOError:
pass
def fix(func):
def f(*args, **kwargs):
return fixed(func, *args, **kwargs)
return f
Then you can use e.g.:
read = fix(read)
to create a fixed version of the function. Similarly for methods:
MyType.my_method = fix(MyType.my_method)
Or you can wrap individual calls, replacing "func(...)" with
"fixed(func, ...)".
