      Convert RDB ziplist loading to sdsnative() · 127c15e2
      Matt Stancliff authored
      This saves us an unnecessary zmalloc, memcpy, and two frees.

      Add sdsnative() · e1619772
      Matt Stancliff authored
      Use the existing memory space for an SDS to convert it to a regular
      character buffer so we don't need to allocate duplicate space just
      to extract a usable buffer for native operations.

      Add adaptive quicklist fill factor · c6bf20c2
      Matt Stancliff authored
      Fill factor now has two options:
        - negative (1-5) for size-based ziplist filling
        - positive for length-based ziplist filling with implicit size cap.
      
      Negative offsets define ziplist size limits of:
        -1: 4k
        -2: 8k
        -3: 16k
        -4: 32k
        -5: 64k
      
      Positive offsets now automatically limit their max size to 8k.  Any
      elements larger than 8k will be in individual nodes.
      
      Positive ziplist fill factors will keep adding elements
      to a ziplist until one of:
        - ziplist has FILL number of elements
          - or -
        - ziplist grows above our ziplist max size (currently 8k)
      
      When using positive fill factors, if you insert a large
      element (over 8k), that element will automatically allocate
      an individual quicklist node with one element and no other elements will be
      in the same ziplist inside that quicklist node.
      
      When using negative fill factors, elements up to the size
      limit can be added to one quicklist node.  If an element
      is added larger than the max ziplist size, that element
      will be allocated an individual ziplist in a new quicklist node.
      
      Tests also updated to start testing at fill factor -5.

      Add ziplistMerge() · 9d2dc024
      Matt Stancliff authored
      This started out as #2158 by sunheehnus, but I kept rewriting it
      until I could understand things more easily and get a few more
      correctness guarantees out of the readability flow.
      
      The original commit created and returned a new ziplist with the contents of
      both input ziplists, but I prefer to grow one of the input ziplists
      and destroy the other one.
      
      So, instead of malloc+copy as in #2158, the merge now reallocs one of
      the existing ziplists and copies the other ziplist into the new space.
      
      Also added merge test cases to ziplistTest()

      Add quicklist implementation · 5e362b84
      Matt Stancliff authored
      This replaces individual ziplist vs. linkedlist representations
      for Redis list operations.
      
      Big thanks for all the reviews and feedback from everybody in
