Comparing a string to the enumerations in pysvn gives me an attribute
error, because they've overloaded the rich compare methods:
import pysvn
"string" in [pysvn.wc_notify_action.status_completed, "string"]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: expecting wc_notify_action object for rich compare
Is there a simple way around this?
Looks like a bug in pysvn. Some class (whatever
pysvn.wc_notify_action.status_completed is) is not well written. When
compared against something unknown, it should return NotImplemented
instead of raising AttributeError.
py> class BadBoy(object):
... foo = 1
... #
... def __eq__(self, other):
... if not isinstance(other, BadBoy):
... raise TypeError, "expecting BadBoy object for rich compare"
... return self.foo==other.foo
...
py> "hello" in [BadBoy(), "hello"]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 6, in __eq__
TypeError: expecting BadBoy object for rich compare

py> class GoodBoy(object):
... foo = 1
... #
... def __eq__(self, other):
... if not isinstance(other, GoodBoy):
... return NotImplemented
... return self.foo==other.foo
...
py> "hello" in [GoodBoy(), "hello"]
True
