Unable to upload small files to glacier

[lyenliang]

I got the following error when uploading a file whose size is less than 4MB

botocore.errorfactory.InvalidParameterValueException: An error occurred (InvalidParameterValueException) when calling the UploadArchive operation: Invalid Content-Length: 0

This error happens at line 70 of upload.py, which is body=file_to_upload,.

The problem seems to be related to file_size = file_to_upload.seek(0, 2) line in upload.py.

Because after I change it to file_size = 1, the problem no longer occurs.

replace

file_size = file_to_upload.seek(0, 2)

with

import os

file_size = os.stat(file_name[0]).st_size
