[New-bugs-announce] [issue10110] Queue doesn't recognize it is full after shrinking maxsize

New submission from Jason R. Coombs <jaraco at jaraco.com>:

The Queue object has a maxsize parameter and attribute, but due to the test for a full queue, shrinking the maxsize could result in the Queue not recognizing that it is full.

The attached patch (against the Python 3 trunk) demonstrates this limitation with a unit test and fixes the failing test case.
