Bug in http.MediaIoBaseDownload

Problem is here. If content-range is not found in response. This will leads to infinite loop because self._total_size will always be None and self._progress == self._total_size will always results in False hence self._done will never be True. Shouldn’t it raise an exception if content-range header is not found?

This is still an issue, and a serious one because it makes it impossible to download objects from Google Cloud Storage buckets using MediaIoBaseDownload.

Here’s another way of getting objects (this does it in one go and stores it in memory, so may not be suitable for large files):

request = client.objects().get_media(bucket="blab", object="blab")
response = request.execute()
print response

For anyone looking for a work around:

def downloadFile(file_name, file_id, mimeType, service):
    request = service.files().get_media(fileId=file_id)
    if "application/vnd.google-apps" in mimeType:
        if "document" in mimeType:
            request = service.files().export_media(fileId=file_id, mimeType='application/vnd.openxmlformats-officedocument.wordprocessingml.document')
            file_name = file_name + ".docx"
        else:
            request = service.files().export_media(fileId=file_id, mimeType='application/pdf')
            file_name = file_name + ".pdf"
    print("Downloading -- " + file_name)
    response = request.execute()
    with open(os.path.join(OUTPUT_DIR, file_name), "wb") as wer:
        wer.write(response)
