      Print command tokens on a crash when hide-user-data-from-log is enabled (#13639) · 54038811
      Ozan Tezcan authored
      If `hide-user-data-from-log` config is enabled, we don't print client
      argv in the crashlog to avoid leaking user info.
      Though, debugging a crash becomes harder as we don't see the command
      arguments causing the crash.
      
      With this PR, we'll be printing command tokens to the log. As we have
      command tokens defined in json schema for each command, using this data,
      we can find tokens in the client argv.
      
      e.g. 
      `SET key value GET EX 10` ---> we'll print `SET * * GET EX *` in the
      log.
      
      Modules should introduce their command structure via
      `RM_SetCommandInfo()`.
      Then, on a crash we'll able to know module command tokens.

      Handle recursive serverAsserts and provide more information for recursive segfaults (#12857) · 068051e3
      Madelyn Olson authored
      This change is trying to make two failure modes a bit easier to deep dive:
      1. If a serverPanic or serverAssert occurs during the info (or module)
      printing, it will recursively panic, which is a lot of fun as it will
      just keep recursively printing. It will eventually stack overflow, but
      will generate a lot of text in the process.
      2. When a segfault happens during the segfault handler, no information
      is communicated other than it happened. This can be problematic because
      `info` may help diagnose the real issue, but without fixing the
      recursive crash it might be hard to get at that info.
