HttpError 416 On 0 byte files

[znorris]

When attempting to download the first chunk of a 0 byte file googleapiclient.http.MediaIoBaseDownload() throws a googleapiclient.errors.HttpError. Modifying the default chunksize does not help.

However, if you remove the header entirely (downloading without chunking) a 0 byte file can be downloaded without receiving a HTTP 416 error.

I'm not sure what anyone thinks of this solutions but currently we're checking for HTTP 200 and 206 response codes before writing the content to file, should we add a condition for 416?

Not sure if I should open a new bug for this one, but there's a similar bug when trying to upload 0 byte files:

fd= BytesIO()
media = googleapiclient.http.MediaIoBaseUpload(fd=fd, chunksize=128, mimetype='text/plain', resumable=True)
body = {'name' : 'foo.txt'}
service.files().create(body=body, media_body=media, fields='id').execute()

Throws

googleapiclient.errors.HttpError: <HttpError 400 when requesting https://www.googleapis.com/upload/drive/v3/files?alt=json&fields=id&uploadType=resumable returned "Bad Request">

The original bug appears to now be fixed (verified by uploading empty file to Drive, then using MediaIoBaseDownload to download it successfully). I'm closing this issue as a result, thanks so much for the report.
