4427 :: walkDir doesn't raises OSError Exception

• timesurfer (orginal) [2018-12-03T09:12:10+01:00] view original

  I'm trying to figure out how to handle error if there are issues with directory permission and user is not able to walk into. as per os.walkDir I think it should raise OSError exception

  iterator walkDir(dir: string; relative = false): tuple[kind: PathComponent, path: string] {.tags: [ReadDirEffect], raises: [OSError].}
  Run

  I'm having scenario such as

  OS : Linux & Mac

  Dir : /tmp/abcd

  case 1 : when abcd doesn't exist

  case 2 : when abcd has permission error ( such as permission 000 ) ( user is not able to go inside as permission error)

  My code looks like this

  import os
  var filepath="/tmp/abcd"
  
  try :
    for kind,path in walkDir(filepath) :
      echo(kind,path)
  except :
      let
          e = getCurrentException()
          msg = getCurrentExceptionMsg()
      echo("Got exception [", e.name, "] , message [", msg,"]")
  
  Run

  in both above cases, I'm not getting any exception and code ending up with null output. I'm not sure how to validate if this is correct behaviour and how can I check this permission error.

  Regards,
