      Fix redis-cli cluster add-node race in cli.tcl (#11349) · a549b78c
      Binbin authored
      There is a race condition in the test:
      ```
      *** [err]: redis-cli --cluster add-node with cluster-port in tests/unit/cluster/cli.tcl
      Expected '5' to be equal to '4' {assert_equal 5 [CI 0 cluster_known_nodes]} proc ::test)
      ```
      
      When using cli to add node, there can potentially be a race condition
      in which all nodes presenting cluster state o.k even though the added
      node did not yet meet all cluster nodes.
      
      This comment and the fix were taken from #11221. Also apply it in several
      other similar places.

      did not yet meet all cluster nodes.
      this adds another utility function to wait until all cluster nodes see the same cluster size

      Fix assertion when a key is lazy expired during cluster key migration (#11176) · c789fb0a
      Oran Agra authored
      Redis 7.0 has #9890 which added an assertion when the propagation queue
      was not flushed and we got to beforeSleep.
      But it turns out that when processCommands calls getNodeByQuery and
      decides to reject the command, it can lead to a key that was lazy
      expired and is deleted without later flushing the propagation queue.
      
      This change prevents lazy expiry from deleting the key at this stage
      (not as part of a command being processed in `call`)

      Gossip forgotten nodes on `CLUSTER FORGET` (#10869) · 5032de50
      Viktor Söderqvist authored
      Gossip the cluster node blacklist in ping and pong messages.
      This means that CLUSTER FORGET doesn't need to be sent to all nodes in a cluster.
      It can be sent to one or more nodes and then be propagated to the rest of them.
      
      For each blacklisted node, its node id and its remaining blacklist TTL is gossiped in a
      cluster bus ping extension (introduced in #9530).

      Fix timing issue in cluster test (#11008) · 5ce64ab0
      Binbin authored
      A timing issue like this was reported in freebsd daily CI:
      ```
      *** [err]: Sanity test push cmd after resharding in tests/unit/cluster/cli.tcl
      Expected 'CLUSTERDOWN The cluster is down' to match '*MOVED*'
      ```
      
      We additionally wait for each node to reach a consensus on the cluster
      state in wait_for_condition to avoid the cluster down error.
      
      The fix just like #10495, quoting madolson's comment:
      Cluster check just verifies the the config state is self-consistent,
      waiting for cluster_state to be okay is an independent check that all
      the nodes actually believe each other are healthy.
      
      At the same time i noticed that unit/moduleapi/cluster.tcl has an exact
      same test, may have the same problem, also modified it.
