[New-bugs-announce] [issue5415] uuid module generates incorrect values for uuid3 (and possibly uuid5)

[René Puls]

New submission from René Puls <rene.puls at repro-mayr.de>:

I am trying to recreate the sample output from appendix B of RFC 4122.

http://www.ietf.org/rfc/rfc4122.txt

In that document, a version 3 UUID is created using the DNS namespace 
(6ba7b810-9dad-11d1-80b4-00c04fd430c8, same as uuid.NAMESPACE_DNS in 
Python) and the name 'www.widgets.com'.

The result according to the RFC should be:

e902893a-9d22-3c7e-a7b8-d6e313b71d9f

Here is the output from the Python uuid module:

>>> import uuid
>>> uuid.NAMESPACE_DNS
UUID('6ba7b810-9dad-11d1-80b4-00c04fd430c8')
>>> uuid.uuid3(uuid.NAMESPACE_DNS, 'www.widgets.com')
UUID('3d813cbb-47fb-32ba-91df-831e1593ac29')

I couldn't find any test cases for the Python module. Did I use it 
incorrectly, or is the calculation really off?
