      sub-command support for ACL CAT and COMMAND LIST. redisCommand always stores fullname (#10127) · 23325c13
      Binbin authored
      
      
      Summary of changes:
      1. Rename `redisCommand->name` to `redisCommand->declared_name`, it is a
        const char * for native commands and SDS for module commands.
      2. Store the [sub]command fullname in `redisCommand->fullname` (sds).
      3. List subcommands in `ACL CAT`
      4. List subcommands in `COMMAND LIST`
      5. `moduleUnregisterCommands` now will also free the module subcommands.
      6. RM_GetCurrentCommandName returns full command name
      
      Other changes:
      1. Add `addReplyErrorArity` and `addReplyErrorExpireTime`
      2. Remove `getFullCommandName` function that now is useless.
      3. Some cleanups about `fullname` since now it is SDS.
      4. Delete `populateSingleCommand` function from server.h that is useless.
      5. Added tests to cover this change.
      6. Add some module unload tests and fix the leaks
      7. Make error messages uniform, make sure they always contain the full command
        name and that it's quoted.
      7. Fixes some typos
      
      see the history in #9504, fixes #10124

      Fix RM_ScanKey module api not to return int encoded strings · a89bf734
      meir@redislabs.com authored
      The scan key module API provides the scan callback with the current
      field name and value (if it exists). Those arguments are RedisModuleString*
      which means it supposes to point to robj which is encoded as a string.
      Using createStringObjectFromLongLong function might return robj that
      points to an integer and so break a module that tries for example to
      use RedisModule_StringPtrLen on the given field/value.
      
      The PR introduces a fix that uses the createObject function and sdsfromlonglong function.
      Using those function promise that the field and value pass to the to the
      scan callback will be Strings.
      
      The PR also changes the Scan test module to use RedisModule_StringPtrLen
      to catch the issue. without this, the issue is hidden because
      RedisModule_ReplyWithString knows to handle integer encoding of the
      given robj (RedisModuleString).
      
      The PR also introduces a new test to verify the issue is solved.

      Added scan implementation to module api. · 11c6ce81
      meir@redislabs.com authored
      The implementation expose the following new functions:
      1. RedisModule_CursorCreate - allow to create a new cursor object for
      keys scanning
      2. RedisModule_CursorRestart - restart an existing cursor to restart the
      scan
      3. RedisModule_CursorDestroy - destroy an existing cursor
      4. RedisModule_Scan - scan keys
      
      The RedisModule_Scan function gets a cursor object, a callback and void*
      (used as user private data).
      The callback will be called for each key in the database proving the key
      name and the value as RedisModuleKey.
