      Change indentation and other minor details of PR #4489. · 522760fa
      antirez authored
      The main change introduced by this commit is pretending that help
      arrays are more text than code, thus indenting them at level 0. This
      improves readability, and is an old practice when defining arrays of
      C strings describing text.
      
      Additionally a few useless return statements are removed, and the HELP
      subcommand capitalized when printed to the user.

      Standardizes the 'help' subcommand · 59d52f7f
      Itamar Haber authored
      This adds a new `addReplyHelp` helper that's used by commands
      when returning a help text. The following commands have been
      touched: DEBUG, OBJECT, COMMAND, PUBSUB, SCRIPT and SLOWLOG.
      
      WIP
      
      Fix entry command table entry for OBJECT for HELP option.
      
      After #4472 the command may have just 2 arguments.
      
      Improve OBJECT HELP descriptions.
      
      See #4472.

      Introduction of a new string encoding: EMBSTR · 894eba07
      antirez authored
      Previously two string encodings were used for string objects:
      
      1) REDIS_ENCODING_RAW: a string object with obj->ptr pointing to an sds
      stirng.
      
      2) REDIS_ENCODING_INT: a string object where the obj->ptr void pointer
      is casted to a long.
      
      This commit introduces a experimental new encoding called
      REDIS_ENCODING_EMBSTR that implements an object represented by an sds
      string that is not modifiable but allocated in the same memory chunk as
      the robj structure itself.
      
      The chunk looks like the following:
      
      +--------------+-----------+------------+--------+----+
      | robj data... | robj->ptr | sds header | string | \0 |
      +--------------+-----+-----+------------+--------+----+
                           |                       ^
                           +-----------------------+
      
      The robj->ptr points to the contiguous sds string data, so the object
      can be manipulated with the same functions used to manipulate plan
      string objects, however we need just on malloc and one free in order to
      allocate or release this kind of objects. Moreover it has better cache
      locality.
      
      This new allocation strategy should benefit both the memory usage and
      the performances. A performance gain between 60 and 70% was observed
      during micro-benchmarks, however there is more work to do to evaluate
      the performance impact and the memory usage behavior.

      Limit memory used by big SLOWLOG entries. · d3701d27
      antirez authored
      Two limits are added:
      
      1) Up to SLOWLOG_ENTRY_MAX_ARGV arguments are logged.
      2) Up to SLOWLOG_ENTRY_MAX_STRING bytes per argument are logged.
      3) slowlog-max-len is set to 128 by default (was 1024).
      
      The number of remaining arguments / bytes is logged in the entry
      so that the user can understand better the nature of the logged command.
