mongofiles should show error when trying to delete non-existent files.

    • Type: Icon: Bug Bug
    • Resolution: Unresolved
    • Priority: Icon: Minor - P4 Minor - P4
    • None
    • Affects Version/s: 3.4.2, 3.4.6
    • Component/s: mongofiles
    • None
    • Environment:
      Tested under MacOS Sierra v 10.12.5

      Tested with v3.4.2 and v3.4.6
      Case 1:
      Delete a non-existent file:
      I only have one GridFS file "mongodb-mms-3.4.6.443-1.x86_64.rpm"

      MongoDB Enterprise replset:PRIMARY> db.fs.files.find()
      { "_id" : ObjectId("59794d50f6f6152271bc57f6"), "chunkSize" : 261120, "uploadDate" : ISODate("2017-07-27T02:19:31.781Z"), "length" : 500329668, "md5" : "ab09ca9a7b9d1c7dbd6225f977c3c057", "filename" : "mongodb-mms-3.4.6.443-1.x86_64.rpm" }
      

      When I tried to delete a non-existent file "something.log", mongofiles still reporting successfully deleted all instances of 'something.log' from GridFS.

      successfully deleted all instances of 'something.log' from GridFS
      

      Case 2:
      I have added a file called “mongod.log” using mongofiles, then I have manually deleted the metadata doc in fs.files, so there would be no reference of “filename”: “mongod.log” in the fs.files collection.

      10gens-MacBook-Pro-3:3.4.2 tomli$ mongofiles put mongod.log
      2017-07-28T14:07:41.958+1000	connected to: localhost
      added file: mongod.log
      
      MongoDB Enterprise replset:PRIMARY> db.fs.files.deleteOne({filename:"mongod.log"})
      { "acknowledged" : true, "deletedCount" : 1 }
      

      When I tried to delete the "mongod.log" file using mongofiles, it reports successfully deleted all instances of "mongod.log" from GridFS. Which it isn't, since all chunks in fs.chunks are not deleted.

      10gens-MacBook-Pro-3:3.4.2 tomli$ mongofiles delete mongod.log -vvvvv
      2017-07-28T14:10:22.545+1000	will listen for SIGTERM, SIGINT, and SIGKILL
      2017-07-28T14:10:22.549+1000	connected to node type: replset

      successfully deleted all instances of 'mongod.log' from GridFS
      

      I think it would be good to catch the exception and return related error message, like: " file not found" etc.
