      Process events with processEventsWhileBlocked() when blocked. · e29d3307
      antirez authored
      When we are blocked and a few events a processed from time to time, it
      is smarter to call the event handler a few times in order to handle the
      accept, read, write, close cycle of a client in a single pass, otherwise
      there is too much latency added for clients to receive a reply while the
      server is busy in some way (for example during the DB loading).

      Accept multiple clients per iteration. · 3a3458ee
      antirez authored
      When the listening sockets readable event is fired, we have the chance
      to accept multiple clients instead of accepting a single one. This makes
      Redis more responsive when there is a mass-connect event (for example
      after the server startup), and in workloads where a connect-disconnect
      pattern is used often, so that multiple clients are waiting to be
      accepted continuously.
      
      As a side effect, this commit makes the LOADING, BUSY, and similar
      errors much faster to deliver to the client, making Redis more
      responsive when there is to return errors to inform the clients that the
      server is blocked in an not interruptible operation.

      clusterLoadConfig() REDIS_ERR retval semantics refined. · e3cf812c
      antirez authored
      We should return REDIS_ERR to signal we can't read the configuration
      because there is no config file only after checking errno, othewise
      we risk to rewrite an existing file that was not accessible for some
      other reason.

      Lock nodes.conf to avoid multiple processes using the same file. · db06108b
      antirez authored
      This was a common source of problems among users.
      The solution adopted is not bullet-proof as if the user deletes the
      nodes.conf file manually, and starts a new instance with the same
      nodes.conf file path, two instances will use the same file. However
      following this reasoning the user may drop a nuclear bomb into the
      datacenter as well.

      Sentinel test files / directories layout improved. · 897adc1c
      antirez authored
      The test now runs in a self-contained directory.
      The general abstractions to run the tests in an environment where
      mutliple instances are executed at the same time was extrapolated into
      instances.tcl, that will be reused to test Redis Cluster.

      Set HLL_SPARSE_MAX to 3000. · 54f0156e
      antirez authored
      After running a few benchmarks, 3000 looks like a reasonable value to
      keep HLLs with a few thousand elements small while the CPU cost is
      still not huge.
      
      This covers all the cases where the dense representation would use N
      orders of magnitude more space, like in the case of many HLLs with
      carinality of a few tens or hundreds.
      
      It is not impossible that in the future this gets user configurable,
      however it is easy to pick an unreasoable value just looking at savings
      in the space dimension without checking what happens in the time
      dimension.
