locks are _AsyncioMutex, whose\nacquire() always went through eventlet.asyncio.spawn_for_awaitable().\nIn a native thread without a hub, such as an eventlet.tpool worker,\nthat created an eventlet hub, and with it an asyncio event loop, just\nto take the lock. Creating the loop logs \"Using selector\" at DEBUG, so\nwith debug logging the record re-entered the lock half way through\nacquiring it. Eventlet stores a thread\u0027s hub before it creates the\nloop, so the nested acquire found a hub that could not run anything\nyet, and the thread\u0027s first log call raised AttributeError (\"\u0027Hub\u0027\nobject has no attribute \u0027sleep_event\u0027\"). A native thread that created\nits hub itself, for example in a monkey-patched time.sleep(), failed\nthe same way while the hub was set up.\n\nA thread without a working hub has no greenlets to exclude, so there\nthe mutex now takes only its RLock, which already excludes the other\nthreads. It records that it did not take the asyncio lock, so release()\nstill matches if the thread gets a hub while it holds the mutex.\n\nRelated-Bug: #1983863\nGenerated-By: Anthropic Claude Opus 5.5\nChange-Id: I54e197699e8ef9bb2a35a59f769356d1cedaf100\nSigned-off-by: Adam Harwell \u003cflux.adam@gmail.com\u003e\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/oslo.log/commit/d22e2f7524bdcb2e19ac499e7e02d4af5a73187d"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/oslo.log/commit/d22e2f7524bdcb2e19ac499e7e02d4af5a73187d"}]},"branch":"refs/heads/master"}},"requirements":[],"submit_records":[{"rule_name":"gerrit~DefaultSubmitRule","status":"OK","labels":[{"label":"Verified","status":"MAY","applied_by":{"_account_id":22348,"name":"Zuul","username":"zuul","tags":["SERVICE_USER"]}},{"label":"Code-Review","status":"MAY"},{"label":"Workflow","status":"MAY"},{"label":"Backport-Candidate","status":"MAY"}]}],"submit_requirements":[{"name":"Verified","description":"Verified in gate by CI","status":"UNSATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Verified\u003dMAX AND -label:Verified\u003dMIN","fulfilled":false,"status":"FAIL","passing_atoms":[],"failing_atoms":["label:Verified\u003dMAX","label:Verified\u003dMIN"],"atom_explanations":{"label:Verified\u003dMAX":"","label:Verified\u003dMIN":""}}},{"name":"Backport-Candidate","description":"Backport candidate status","status":"NOT_APPLICABLE","is_legacy":false,"applicability_expression_result":{"fulfilled":false,"status":"FAIL"},"submittability_expression_result":{"expression":"is:true","fulfilled":true,"status":"NOT_EVALUATED","passing_atoms":[],"failing_atoms":[],"atom_explanations":{}}},{"name":"Code-Review","description":"Code reviewed by core reviewer","status":"UNSATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Code-Review\u003dMAX AND -label:Code-Review\u003dMIN","fulfilled":false,"status":"FAIL","passing_atoms":[],"failing_atoms":["label:Code-Review\u003dMAX","label:Code-Review\u003dMIN"],"atom_explanations":{"label:Code-Review\u003dMAX":"","label:Code-Review\u003dMIN":""}}},{"name":"Workflow","description":"Approved for gate by core reviewer","status":"UNSATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Workflow\u003dMAX AND -label:Workflow\u003dMIN","fulfilled":false,"status":"FAIL","passing_atoms":[],"failing_atoms":["label:Workflow\u003dMAX","label:Workflow\u003dMIN"],"atom_explanations":{"label:Workflow\u003dMAX":"","label:Workflow\u003dMIN":""}}}]}
