-----------------------------------

             Summary: BLPOP command does not trigger when the target List is created via a RENAME
                 Key: GEODE-10191
                 URL: https://issues.apache.org/jira/browse/GEODE-10191
             Project: Geode
          Issue Type: Bug
          Components: redis
    Affects Versions: 1.15.0
            Reporter: Donal Evans


BLPOP uses fired events from the LPUSH and RPUSH commands to trigger returning, but it is also possible that a key will be created via RENAME, which does not currently fire any events. The test below passes with open source Redis but fails/hangs with geode-for-redis:
{code:java}
@Test
public void testBLPopWhenValueGetsCreated_withRename() throws Exception {
  String initialName = "{tag}initial";
  String changedName = "{tag}changed";
  jedis.lpush(initialName, "value1", "value2");
  Future<List<String>> future = executor.submit(() -> jedis.blpop(0, changedName));

  awaitEventDistributorSize(1);
  jedis.rename(initialName, changedName);

  assertThat(future.get()).containsExactly(changedName, "value2");
  assertThat(jedis.lpop(changedName)).isEqualTo("value1");
} {code}
The RENAME command should be modified so that it fires events for the key being created.
