      sdscatfmt() added to SDS library. · 0ab06bb5
      antirez authored
      sdscatprintf() relies on printf() family libc functions and is sometimes
      too slow in critical code paths. sdscatfmt() is an alternative which is:
      
      1) Far less capable.
      2) Format specifier uncompatible.
      3) Faster.
      
      It is suitable to be used in those speed critical code paths such as
      CLIENT LIST output generation.

      Process events with processEventsWhileBlocked() when blocked. · cdd2bd56
      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. · 357b039f
      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. · b008863e
      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. · 71d71814
      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. · a0050e50
      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.
