      Threaded IO: set thread name for redis-server · 5010da6a
      zhenwei pi authored
      
      
      Set thread name for each thread of redis-server, this helps us to
      monitor the utilization and optimise the performance.
      
      And suggested-by Salvatore, implement this feature for multi
      platforms. Currently support linux and bsd, ignore other OS.
      
      An exmaple on Linux:
       # top -d 5 -p `pidof redis-server ` -H
      
          PID USER      PR  NI    VIRT    RES    SHR S %CPU %MEM     TIME+ COMMAND
      3682671 root      20   0  227744   8248   3836 R 99.2  0.0   0:19.53 redis-server

      3682678 root      20   0  227744   8248   3836 S  0.0  0.0   0:00.00 jemalloc_bg_thd

      3682684 root      20   0  227744   8248   3836 S  0.0  0.0   0:00.00 jemalloc_bg_thd
      3682685 root      20   0  227744   8248   3836 S  0.0  0.0   0:00.00 jemalloc_bg_thd

      Speedup INFO by counting client memory incrementally. · f6987628
      antirez authored
      Related to #5145.
      
      Design note: clients may change type when they turn into replicas or are
      moved into the Pub/Sub category and so forth. Moreover the recomputation
      of the bytes used is problematic for obvious reasons: it changes
      continuously, so as a conservative way to avoid accumulating errors,
      each client remembers the contribution it gave to the sum, and removes
      it when it is freed or before updating it with the new memory usage.

      Fix duplicated CLIENT SETNAME reply. · 6e4f70b8
      antirez authored
      Happened when we set the name to "" to cancel the name.
      Was introduced during the RESP3 refactoring.
      
      See #6036.

      Inline protocol: handle empty strings well. · 5521910d
      antirez authored
      This bug is from the first version of Redis. Probably the problem here
      is that before we used an SDS split function that created empty strings
      for additional spaces, like in "SET    foo          bar".
      AFAIK later we replaced it with the curretn sdssplitarg() API that has
      no such a problem. As a result, we introduced a bug, where it is no
      longer possible to do something like:
      
          SET foo ""
      
      Using the inline protocol. Now it is fixed.

      Module API for loading and saving long double · 779aebc9
      Oran Agra authored
      looks like each platform implements long double differently (different bit count)
      so we can't save them as binary, and we also want to avoid creating a new RDB
      format version, so we save these are hex strings using "%La".
      
      This commit includes a change in the arguments of ld2string to support this.
      as well as tests for coverage and short reads.

      Modules hooks: complete missing hooks for the initial set of hooks · 51c3ff8d
      Oran Agra authored
      * replication hooks: role change, master link status, replica online/offline
      * persistence hooks: saving, loading, loading progress
      * misc hooks: cron loop, shutdown, module loaded/unloaded
      * change the way hooks test work, and add tests for all of the above
      
      startLoading() now gets flag indicating what is loaded.
      stopLoading() now gets an indication of success or failure.
      adding startSaving() and stopSaving() with similar args and role.

      diskless replication rdb transfer uses pipe, and writes to sockets form the parent process. · 5a477946
      Oran Agra authored
      misc:
      - handle SSL_has_pending by iterating though these in beforeSleep, and setting timeout of 0 to aeProcessEvents
      - fix issue with epoll signaling EPOLLHUP and EPOLLERR only to the write handlers. (needed to detect the rdb pipe was closed)
      - add key-load-delay config for testing
      - trim connShutdown which is no longer needed
      - rioFdsetWrite -> rioFdWrite - simplified since there's no longer need to write to multiple FDs
      - don't detect rdb child exited (don't call wait3) until we detect the pipe is closed
      - Cleanup bad optimization from rio.c, add another one
