      Cluster: introduce data_received field. · 00a3bc43
      antirez authored
      We want to send pings and pongs at specific intervals, since our packets
      also contain information about the configuration of the cluster and are
      used for gossip. However since our cluster bus is used in a mixed way
      for data (such as Pub/Sub or modules cluster messages) and metadata,
      sometimes a very busy channel may delay the reception of pong packets.
      So after discussing it in #7216, this commit introduces a new field that
      is not exposed in the cluster, is only an internal information about
      the last time we received any data from a given node: we use this field
      in order to avoid detecting failures, claiming data reception of new
      data from the node is a proof of liveness.

      Support setcpuaffinity on linux/bsd · 1a0deab2
      zhenwei pi authored
      Currently, there are several types of threads/child processes of a
      redis server. Sometimes we need deeply optimise the performance of
      redis, so we would like to isolate threads/processes.
      
      There were some discussion about cpu affinity cases in the issue:
      https://github.com/antirez/redis/issues/2863
      
      
      
      So implement cpu affinity setting by redis.conf in this patch, then
      we can config server_cpulist/bio_cpulist/aof_rewrite_cpulist/
      bgsave_cpulist by cpu list.
      
      Examples of cpulist in redis.conf:
      server_cpulist 0-7:2      means cpu affinity 0,2,4,6
      bio_cpulist 1,3           means cpu affinity 1,3
      aof_rewrite_cpulist 8-11  means cpu affinity 8,9,10,11
      bgsave_cpulist 1,10-11    means cpu affinity 1,10,11
      
      Test on linux/freebsd, both work fine.

      optimize memory usage of deferred replies - fixed · 6726b3c2
      Oran Agra authored
      When deffered reply is added the previous reply node cannot be used so
      all the extra space we allocated in it is wasted. in case someone uses
      deffered replies in a loop, each time adding a small reply, each of
      these reply nodes (the small string reply) would have consumed a 16k
      block.
      now when we add anther diferred reply node, we trim the unused portion
      of the previous reply block.
      
      see #7123
      
      cherry picked from commit fb732f7a
      with fix to handle a crash with LIBC allocator, which apparently can
      return the same pointer despite changing it's size.
      i.e. shrinking an allocation of 16k into 56 bytes without changing the
      pointer.

      Cast printf() argument to the format specifier. · a07a4ada
      antirez authored
      We could use uint64_t specific macros, but after all it's simpler to
      just use an obvious equivalent type plus casting: this will be a no op
      and is simpler than fixed size types printf macros.
