----------------------------------
Summary: Windows UUID processing mingles GUID values
Key: QPID-4792
URL: https://issues.apache.org/jira/browse/QPID-4792
Project: Qpid
Issue Type: Bug
Components: C++ Broker, C++ Client
Affects Versions: 0.20
Environment: Windows
Reporter: Cliff Jansen
Assignee: Cliff Jansen
Fix For: 0.23
RFC 4122 defines a UUID. A GUID is the same as a UUID in string form, but
differs in binary layout. Microsoft operates with GUIDs but confusingly labels
them as UUIDs in their documentation and include files.
i.e. rpcdce.h: typedef GUID UUID;
The binary form matters since it is used over the wire. Mapping a GUID to a
UUID (or vice versa) without the layout conversion results in structures with
mangled RFC version info and different string representations on Windows and
non-Windows systems.
Proton currently only calls Microsoft APIs to obtain the string representation
of the UUID (which will match the GUID), so it is unaffected.
