Aborted upload causes Sails js/Skipper to crash

问题

Ref: https://github.com/balderdashy/skipper/issues/49

Adapter: skipper-gridfs

Basic controller code:

req.file('fileTest')
        .upload({

        // You can apply a file upload limit (in bytes)
        maxBytes: maxUpload,
        adapter: require('skipper-gridfs'),
        uri: bucketConnect,
        saveAs : function (__newFileStream,cb) {
            cb(null, __newFileStream.filename);
        }

    }, function whenDone(err, uploadedFiles) {
        if (err) {
            var error = {  "status": 500, "error" : err };
            return res.serverError(error);
        }else {

I have a jQuery-File-Upload client ( https://blueimp.github.io/jQuery-File-Upload/ ) impementing the "cancel" procedure by using jqXHR abort described here (https://github.com/blueimp/jQuery-File-Upload/wiki/API ):

$('button.cancel').click(function (e) {
    jqXHR.abort();
});

After the client aborts, the server crashes with the following message:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: Request aborted
    at IncomingMessage.onReqAborted (.../node_modules/sails/node_modules/skipper/node_modules/multiparty/index.js:175:17)
    at IncomingMessage.EventEmitter.emit (events.js:92:17)
    at abortIncoming (http.js:1911:11)
    at Socket.serverSocketCloseListener (http.js:1923:5)
    at Socket.EventEmitter.emit (events.js:117:20)
    at TCP.close (net.js:466:12)

I've used try/catch but it didn't work, the server crashes anyway.

I am not sure if this is a Skipper issue or a Multiparty issue -- my knowledge stops here ( https://github.com/andrewrk/node-multiparty/blob/master/index.js ):

function onReqAborted() {
    waitend = false;
    self.emit('aborted');
    handleError(new Error("Request aborted"));
  }

  function onReqEnd() {
    waitend = false;
  }

  function handleError(err) {
    var first = !self.error;
    if (first) {
      self.error = err;
      req.removeListener('aborted', onReqAborted);
      req.removeListener('end', onReqEnd);
      if (self.destStream) {
        self.destStream.emit('error', err);
      }
    }

    cleanupOpenFiles(self);

    if (first) {
      self.emit('error', err);
    }
  }

At first I thought this was the way the jqXHR request was aborted, but it seems to be a generic Skipper issue on aborted uploads, since the simple act of closing the tab during an upload will crash the server (different message):

_stream_writable.js:233
    cb(er);
    ^
TypeError: object is not a function
    at onwriteError (_stream_writable.js:233:5)
    at onwrite (_stream_writable.js:253:5)
    at WritableState.onwrite (_stream_writable.js:97:5)
    at Writable.<anonymous> (.../node_modules/skipper-gridfs/index.js:179:25)

    at Writable.EventEmitter.emit (events.js:117:20)
    at PassThrough.<anonymous> (.../node_modules/skipper-gridfs/index.js:194:36)

    at PassThrough.EventEmitter.emit (events.js:117:20)
    at .../node_modules/sails/node_modules/skipper/standalone/Upstream/prototype.fatalIncomingError.js:55:17

I have tried aborting the upload by closing the tab while using a simple upload controller (not Skipper) and there is no crash:

var uploadFile = req.file('fileTest');
    console.log(uploadFile);

    uploadFile.upload(function onUploadComplete (err, files) {                // Files will be uploaded to .tmp/uploads

        if (err) return res.serverError(err);                              // IF ERROR Return and send 500 error with error

        console.log(files);
        res.json({status:200,file:files});
    });

So, did anybody see this happening and is there any workaround?
