[Test Case]
+ This is reproducable by raising an AssertionError in the initialization
+ of MyCache and looks like a problem with
+ "UpdateManager/backend/__init__.py" carrying on when cache is set to
+ None. Here are the lines of code I'm looking at:
+
+ except Exception as e:
+ logging.debug("error reading cache (%s)" % e)
+ cache = None
[Regression Potential]
+
+ Instead of assigning the cache to None and attempting to continue the
+ duplicates check, we now just return an empty array. It's perfectly safe
+ to postpone this duplicates check to a later update, so there's little
+ regression potential in my opinion.
