      Implement `SCAN cursor [TYPE type]` modifier suggested in issue #6107. · bf963253
      Angus Pearson authored
      Add tests to check basic functionality of this optional keyword, and also tested with
      a module (redisgraph). Checked quickly with valgrind, no issues.
      
      Copies name the type name canonicalisation code from `typeCommand`, perhaps this would
      be better factored out to prevent the two diverging and both needing to be edited to
      add new `OBJ_*` types, but this is a little fiddly with C strings.
      
      The [redis-doc](https://github.com/antirez/redis-doc/blob/master/commands.json) repo
      will need to be updated with this new arg if accepted.
      
      A quirk to be aware of here is that the GEO commands are backed by zsets not their own
      type, so they're not distinguishable from other zsets.
      
      Additionally, for sparse types this has the same behaviour as `MATCH` in that it may
      return many empty results before giving something, even for large `COUNT`s.

      Streams: fix xreadGetKeys() for correctness. · 20766608
      antirez authored
      The old version could not handle the fact that "STREAMS" is a valid key
      name for streams. Now we really try to parse the command like the
      command implementation would do.
      
      Related to #5028 and 4857.

      Streams: fix xreadGetKeys() buffer overflow. · a0b27dae
      antirez authored
      The loop allocated a buffer for the right number of keys positions, then
      overflowed it going past the limit.
      
      Related to #4857 and cause of the memory violation seen in #5028.

      Fix getKeysUsingCommandTable() in the case of nagative arity. · 2f8476df
      antirez authored
      This fixes a crash with Redis Cluster when OBJECT is mis-used, because
      getKeysUsingCommandTable() will call serverPanic() detecting we are
      accessing an invalid argument in the case "OBJECT foo" is called.
      
      This bug was introduced when OBJECT HELP was introduced, because the key
      argument is set fixed at index 2 in the command table, however now
      OBJECT may be called with an insufficient number of arguments to extract
      the key.
      
      The "Right Thing" would be to have a specific function to extract keys
      from the OBJECT command, however this is kinda of an overkill, so I
      preferred to make getKeysUsingCommandTable() more robust and just return
      no keys when it's not possible to honor the command table, because new
      commands are often added and also there are a number with an HELP
      subcommand violating the normal form, and crashing for this trivial
      reason or having many command-specific key extraction functions is not
      great.

      LFU: do some changes about LFU to find hotkeys · 583c3147
      zhaozhao.zz authored
      Firstly, use access time to replace the decreas time of LFU.
      For function LFUDecrAndReturn,
      it should only try to get decremented counter,
      not update LFU fields, we will update it in an explicit way.
      And we will times halve the counter according to the times of
      elapsed time than server.lfu_decay_time.
      Everytime a key is accessed, we should update the LFU
      including update access time, and increment the counter after
      call function LFUDecrAndReturn.
      If a key is overwritten, the LFU should be also updated.
      Then we can use `OBJECT freq` command to get a key's frequence,
      and LFUDecrAndReturn should be called in `OBJECT freq` command
      in case of the key has not been accessed for a long time,
      because we update the access time only when the key is read or
      overwritten.
