[Helma-user] file upload monitoring

[kRAkEn/gORe]

no i was rather mistaking things. i was getting empty form when doing
the progress get (obviously cause a simple periodical exeucter via
ajax was done), in the post all is working correctly. forget

with your example, i've got tried exceed maximum upload bytes
deliberately, but the overall response takes ages to come back to the
client so when doing periodical executions to get the progress they
takes 60-80 seconds to complete (with uploadSoftfail and checking for
req.data.helma_upload_error). i have something like this in my server
action class:

    initialize: function ()
    {
        this.parent ();

        if (req.data.helma_upload_error != undefined)
        {
            this.status = "MaxSizeReached";
            this.onResponse ();
        }
    },

	onAction: function ()
	{
        this.uploadDirectory = this.uploadDirectory || Config.getValue
("tempUploadDirectory");

        var status = session.getUploadStatus (req.data.upload_id);
        if (status != null)
        {
            this.upload = {
                current: status.current,
                total: status.total,
                itemsRead: status.itemsRead,
                error: status.error
            };
        }

        if (req.isPost())
        {
            if (status && status.getCurrent() == status.getTotal())
            {
                var files = this._saveAllFiles (status, this.uploadDirectory);

                this.onUploadCompleted (files);
            }
        }
        else if (status)
        {
            this.data = this.upload;
            this.status = "Progress";
        }
	}


but then the periodicalExecuter on the client takes ages to complete...
