[zope2-tracker] [Bug 1236354] [NEW] BooleanIndex index becomes wrong when index value is inverted during a RE-indexation

[Thomas Desvenain]

Public bug reported:

This test (for now in tdesvenain fork) fails :
self.assertEqual(list(res), [1, 3, 4]) is wrong because '1' document is always indexed with False value

    def test_reindexation_when_index_reversed(self):
        index = self._makeOne()
        obj1 = Dummy(1, False)
        index._index_object(obj1.id, obj1, attr='truth')
        obj2 = Dummy(2, False)
        self.assertTrue(index._index_value)
        index._index_object(obj2.id, obj2, attr='truth')
        obj3 = Dummy(3, True)
        index._index_object(obj3.id, obj3, attr='truth')
        obj4 = Dummy(4, True)
        index._index_object(obj4.id, obj4, attr='truth')
        obj1.truth = True
        index._index_object(obj1.id, obj1, attr='truth')
        self.assertFalse(index._index_value)

        res = index._apply_index({'truth': True})[0]
        self.assertEqual(list(res), [1, 3, 4])
