Bug Description

By trying to add an image to Glance on Windows with:

glance image-create --name="Image name" --container-format ovf --disk-format qcow2 --file image.img

or

glance image-create --name="Image name" --container-format ovf --disk-format qcow2 < image.img

the upload will hang if the file contains a byte with value 0x1A (EOF), due to the fact that the file and stdin streams are treated as text and not binary streams.

The same issue applies to "image-update" and the equivalent deprecated "add" and "update" commands.

The fix consists in setting the streams in binary mode in both cases:

File: python-glanceclient\glanceclient\v1\shell.py

    if 'location' not in fields and 'copy_from' not in fields:
        if args.file:
            fields['data'] = open(args.file, 'rb')
        else:
            if os.name == 'nt':
                msvcrt.setmode(sys.stdin.fileno(), os.O_BINARY)
            fields['data'] = sys.stdin

    The image upload hangs if the file contains a byte with value 0x1A (EOF), due to
    the fact that the file or stdin streams are treated as text and not
    binary streams. This fix sets the proper binary mode.
