has no attribute 'endpoint_override'
+ [ Impact ]
+ * Nova's neutron client wrapper fails under Python 3.13 due to a
+ garbage collection bug in CPython that causes dictionary references to
+ be prematurely cleared when one object's __dict__ is assigned to another
+ object's __dict__. This completely prevents users from being able to
+ spawn virtual VMs (or do other communication to Neutron that span
+ multiple cpu cycles), which is the main purpose of Nova.
- This using Plucky Proposed - 25.04
- nova-compute: 3:30.0.0+git2025030311.e6b8b051a9-0ubuntu1
+ * This bug fix stops ClientWrapper from inheriting clientv20.Client and
+ directly referencing the base_client's __dict__. This allows
+ ClientWrapper to act as a true proxy for clientv20.Client while
+ preventing the cache inlining bug that leads to garbage collection.
- This nova compute version is a snapshot of current master branch from
- the Nova project, RC1 will soon be available:
- https://review.opendev.org/c/openstack/releases/+/943941
+ [ Test Plan ]
- This happens during testing with Tempest, in tests such as:
-
tempest.scenario.test_network_basic_ops.TestNetworkBasicOps.test_network_basic_ops
+ * With a configured Nova, spawn a VM.
+ To simplify testing, I've written a configuration script to help create a
single node OpenStack cloud as VM: https://pastebin.ubuntu.com/p/JkHXBmKBbm/
- Nova should successfully create a VM
+ [ Where problems could occur ]
- Nova failed to communicate with neutron because of an attribute error
+ * The change modifies how the ClientWrapper class accesses attributes
+ from the underlying neutron client. If the __getattr__ implementation
+ doesn't properly handle all attribute types or edge cases, it could
+ result in AttributeError exceptions or unexpected behavior when
+ accessing client methods or properties.
- I've tested the same version of Nova using the Epoxy Cloud archive from
- proposed, and it worked correctly.
+ * Since this changes the inheritance model (from inheritance to
+ composition), any code that relies on isinstance() checks against
+ clientv20.Client for the wrapper would fail.
+
+ [ Other Info ]
+
+ * This patch comes directly from upstream Nova and has been back-ported
+ upstream to stable/2025.1, commit
+ bdf62d0653c2e31ae291fc51e7016407b19f6ff4.
+
+ * The fix specifically addresses Python 3.13 compatibility. The
+ behavior is correct on Python 3.12 and earlier versions, but Python 3.13
+ exhibits the dictionary clearing issue.
