New submission from Alex Willmer:
The maxsize argument when initializing a Queue is expected to be an int
(technically anything that can be compared to an int). However the class takes
any value. In Python 3 this throws "TypeError: unorderable types" once e.g.
.put() is called.
On the basis that errors should not pass silent, should maxsize be checked for
compatibility at initialization time? e.g.
Desired:
>>> import queue
>>> q = queue.Queue(range(10))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.5/queue.py", line nnn, in __init__()
...
TypeError: 'range' object cannot be interpreted as an integer
Actual:
Python 3.5.0rc2 (default, Aug 25 2015, 20:29:07)
[GCC 5.2.1 20150825] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import queue
>>> q = queue.Queue(range(10)) # Silently accepts an invalid maxsize
>>> q.put('foo')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.5/queue.py", line 127, in put
if self.maxsize > 0:
TypeError: unorderable types: range() > int()
