Jonathan Ellis commented on CASSANDRA-386:
------------------------------------------
this test passes for me:
def test_long_remove(self):
path = ColumnPath('StandardLong1', column=_i64(1))
client.insert('Keyspace1', 'key1', path, 'value1', 0,
ConsistencyLevel.ONE)
client.remove('Keyspace1', 'key1', path, 1, ConsistencyLevel.ONE)
_expect_missing(lambda: client.get('Keyspace1', 'key1', path,
ConsistencyLevel.ONE))
L = client.get_key_range('Keyspace1', 'StandardLong1', '', '', 10)
assert L == [], L
# resurrect
client.insert('Keyspace1', 'key1', path, 'value2', 2,
ConsistencyLevel.ONE)
c = client.get('Keyspace1', 'key1', path, ConsistencyLevel.ONE).column
assert c.value == 'value2', c
L = client.get_key_range('Keyspace1', 'StandardLong1', '', '', 10)
assert L == ['key1'], L

> jbellis: what is "mis applying?"
> evn: later inserts have no effect
> jbellis: so you do a remove with timestamp X, then timestamp X + 1 has no
> effect?
> evn: yeah
> jbellis: did you try a similar test w/ a ascii comparewith?
> evn: well the identical test passes w/ TimeUUIDType
