You can merge this patch set with mine and do the style changes. And to do not block the UI patch, disable the upload option by now until we get the backend updated. Royce, For the backend I imagine we can allow receive multiple POST request to get the whole file while uploading it. Example: POST /storagepools/<pool>/storagevolumes/ {file: fd} this fd object will have : - fd.file: a part of 10MB of the file to be uploaded - fd.part: the correspond part number - fd.total: total number of parts to be received The UI will do something like: fd.total = round(fd.size / 10MB) transfered = 0 part = 0 while part < fd.total: fd.file = read more 10MB of the file fd.part = part POST POST /storagepools/<pool>/storagevolumes/ {file: fd} fd.part++ On backend: if os.path.exists(filepath) and fd.part = 0: raise InvalidParemeter("file already exists") localfile = open(filepath, a) localfile.seek(fd.part * 10MB) localfile.write(fd.file)
