      The CTRL-C behavior changes compared to the old shell:

      • Hitting CTRL-C will not kill the shell (directly, only when hit multiple times)
      • CTRL-C will stop execution of code and also terminate any operations that are running on the server

      Known cases where CTRL-C *WILL NOT* terminate operations on the server reliably:

      • On MongoDB Server v4.0.x (only works on v4.1.x and above)
      • When the user code contains explicit asynchronous code - like the use of setTimeout, setImmediate, or things like fs.readFile (which were not available in the old shell). The behavior there is the same as with the default Node.js REPL - as it is not possible to kill async code execution.

      User Story

      As a user,
      I want to be able to gracefully interrupt running commands,
      So that I can quickly stop a command that I typed wrong and get back to the prompt to try again

      Acceptance Criteria

      • Ctrl-C gracefully interrupts the active command
      • When the command is interrupted, the shell will attempt to cleanly terminate the operation on the server and print a warning if that is not possible
      • After the command is interrupted, the user gets back to the prompt and can run the next command
      • Ctrl-C does not terminate the shell
