Donal Evans created GEODE-10191:
-----------------------------------
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.
