      make active defrag test more stable · f89c93c8
      Oran Agra authored
      on slower machines, the active defrag test tended to fail.
      although the fragmentation ratio was below the treshold, the defragger was
      still in the middle of a scan cycle.
      
      this commit changes:
      - the defragger uses the current fragmentation state, rather than the cache one
        that is updated by server cron every 100ms. this actually fixes a bug of
        starting one excess scan cycle
      - the test lets the defragger use more CPU cycles, in hope that the defrag
        will be faster, but also give it more time before we give up.

      slave buffers were wasteful and incorrectly counted causing eviction · bf680b6f
      Oran Agra authored
      A) slave buffers didn't count internal fragmentation and sds unused space,
         this caused them to induce eviction although we didn't mean for it.
      
      B) slave buffers were consuming about twice the memory of what they actually needed.
      - this was mainly due to sdsMakeRoomFor growing to twice as much as needed each time
        but networking.c not storing more than 16k (partially fixed recently in 237a38737).
      - besides it wasn't able to store half of the new string into one buffer and the
        other half into the next (so the above mentioned fix helped mainly for small items).
      - lastly, the sds buffers had up to 30% internal fragmentation that was wasted,
        consumed but not used.
      
      C) inefficient performance due to starting from a small string and reallocing many times.
      
      what i changed:
      - creating dedicated buffers for reply list, counting their size with zmalloc_size
      - when creating a new reply node from, preallocate it to at least 16k.
      - when appending a new reply to the buffer, first fill all the unused space of the
        previous node before starting a new one.
      
      other changes:
      - expose mem_not_counted_for_evict info field for the benefit of the test suite
      - add a test to make sure slave buffers are counted correctly and that they don't cause eviction

      Enhance RESTORE with RDBv9 new features · b5197f1f
      Guy Benoish authored
      RESTORE now supports:
      1. Setting LRU/LFU
      2. Absolute-time TTL
      
      Other related changes:
      1. RDB loading will not override LRU bits when RDB file
         does not contain the LRU opcode.
      2. RDB loading will not set LRU/LFU bits if the server's
         maxmemory-policy does not match.

      problems fixed:
      * failing to read fragmentation information from jemalloc
      * overflow in jemalloc fragmentation hint to the defragger
      * test suite not triggering eviction after population
