      Repurpose redisCommandArg's name as the unique ID (#11051) · 223046ec
      guybe7 authored
      This PR makes sure that "name" is unique for all arguments in the same
      level (i.e. all args of a command and all args within a block/oneof).
      This means several argument with identical meaning can be referred to together,
      but also if someone needs to refer to a specific one, they can use its full path.
      
      In addition, the "display_text" field has been added, to be used by redis.io
      in order to render the syntax of the command (for the vast majority it is
      identical to "name" but sometimes we want to use a different string
      that is not "name")
      The "display" field is exposed via COMMAND DOCS and will be present
      for every argument, except "oneof" and "block" (which are container
      arguments)
      
      Other changes:
      1. Make sure we do not have any container arguments ("oneof" or "block")
         that contain less than two sub-args (otherwise it doesn't make sense)
      2. migrate.json: both AUTH and AUTH2 should not be "optional"
      3. arg names cannot contain underscores, and force the usage of hyphens
        (most of these were a result of the script that generated the initial json files
        from redis.io commands.json).

      Fix redis-cli with sentinel crash due to SENTINEL DEBUG missing summary (#10250) · b95beeb5

      Fix redis-cli with sentinel crash due to SENTINEL DEBUG missing summary
      
      Because SENTINEL DEBUG missing summary in its json file,
      with the change in #10043, the following assertion will fail.
      ```
      [redis]# src/redis-cli -p 26379
      redis-cli: redis-cli.c:678: cliInitCommandHelpEntry: Assertion `reply->type == 1' failed.
      ```
      
      This commit add the summary and complexity for SENTINEL DEBUG,
      which introduced in #9291, and also improved the help message.

      Auto-generate the command table from JSON files (#9656) · 86781600
      guybe7 authored
      Delete the hardcoded command table and replace it with an auto-generated table, based
      on a JSON file that describes the commands (each command must have a JSON file).
      
      These JSON files are the SSOT of everything there is to know about Redis commands,
      and it is reflected fully in COMMAND INFO.
      
      These JSON files are used to generate commands.c (using a python script), which is then
      committed to the repo and compiled.
      
      The purpose is:
      * Clients and proxies will be able to get much more info from redis, instead of relying on hard coded logic.
      * drop the dependency between Redis-user and the commands.json in redis-doc.
      * delete help.h and have redis-cli learn everything it needs to know just by issuing COMMAND (will be
        done in a separate PR)
      * redis.io should stop using commands.json and learn everything from Redis (ultimately one of the release
        artifacts should be a large JSON, containing all the information about all of the commands, which will be
        generated from COMMAND's reply)
      * the byproduct of this is:
        * module commands will be able to provide that info and possibly be more of a first-class citizens
        * in theory, one may be able to generate a redis client library for a strictly typed language, by using this info.
      
      ### Interface changes
      
      #### COMMAND INFO's reply change (and arg-less COMMAND)
      
      Before this commit the reply at index 7 contained the key-specs list
      and reply at index 8 contained the sub-commands list (Both unreleased).
      Now, reply at index 7 is a map of:
      - summary - short command description
      - since - debut version
      - group - command group
      - complexity - complexity string
      - doc-flags - flags used for documentation (e.g. "deprecated")
      - deprecated-since - if deprecated, from which version?
      - replaced-by - if deprecated, which command replaced it?
      - history - a list of (version, what-changed) tuples
      - hints - a list of strings, meant to provide hints for clients/proxies. see https://github.com/redis/redis/issues/9876
      - arguments - an array of arguments. each element is a map, with the possibility of nesting (sub-arguments)
      - key-specs - an array of keys specs (already in unstable, just changed location)
      - subcommands - a list of sub-commands (already in unstable, just changed location)
      - reply-schema - will be added in the future (see https://github.com/redis/redis/issues/9845)
      
      more details on these can be found in https://github.com/redis/redis-doc/pull/1697
      
      only the first three fields are mandatory 
      
      #### API changes (unreleased API obviously)
      
      now they take RedisModuleCommand opaque pointer instead of looking up the command by name
      
      - RM_CreateSubcommand
      - RM_AddCommandKeySpec
      - RM_SetCommandKeySpecBeginSearchIndex
      - RM_SetCommandKeySpecBeginSearchKeyword
      - RM_SetCommandKeySpecFindKeysRange
      - RM_SetCommandKeySpecFindKeysKeynum
      
      Currently, we did not add module API to provide additional information about their commands because
      we couldn't agree on how the API should look like, see https://github.com/redis/redis/issues/9944
      
      .
      
      ### Somehow related changes
      1. Literals should be in uppercase while placeholder in lowercase. Now all the GEO* command
         will be documented with M|KM|FT|MI and can take both lowercase and uppercase
      
      ### Unrelated changes
      1. Bugfix: no_madaory_keys was absent in COMMAND's reply
      2. expose CMD_MODULE as "module" via COMMAND
      3. have a dedicated uint64 for ACL categories (instead of having them in the same uint64 as command flags)
