a Timestamp with\nnon-zero offset. A disadvantage of that implementation is that\ninverted Timestamps do not always sort in the reverse order of the\noriginal Timestamps. Specifically, a Timestamp with zero offset sorts\n*before* a Timestamp with the same float part but non-zero offset, but\nthe inverse of a Timestamp with zero offset also sorts *before* the\ninverse of a Timestamp with the same float part but non-zero offset.\n\nThis patch improves the inversion to ensure that the inverse of a\nTimestamp with zero offset sorts *after* the inverse of a Timestamp\nwith the same float part but non-zero offset. This is achieved by\nredefining the maximum Timestamp.internal value as\n\"9999999999.99999_0000000000000000\" rather than\n\"9999999999.99999_ffffffffffffffff\".\n\nThe only known use of Timestamp inversion is by object versioning\nmiddleware, where timestamps are not yet expected to ever have\nnon-zero offset. This patch, like the Related-Change, is in\nanticipation of *future* inverted timestamps having non-zero hex\nparts. There is therefore no known impact from modifyng the\nTimestamp.__invert__ implementation at this time.\n\nThis patch preserves the property that the inverse of a Timestamp with\nzero offset also has zero offset.\n\nRelated-Change: I4898c8250fe85dbbf66d0ab3d24b0ae9802820f5\nChange-Id: If0b5f11f38405e69ae1b54d73b667abf0abfb89b\nSigned-off-by: Tim Burke \u003ctim.burke@gmail.com\u003e\n(cherry picked from commit 694d25bb1a87f9426ac7ad1f3817c51f5bf13a34)\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/swift/commit/8c41239fdbcd57164f92328356de07f9b0991c42"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/swift/commit/8c41239fdbcd57164f92328356de07f9b0991c42"}]},"branch":"refs/heads/stable/2026.1"}},"requirements":[],"submit_records":[{"rule_name":"gerrit~DefaultSubmitRule","status":"CLOSED","labels":[{"label":"Verified","status":"MAY","applied_by":{"_account_id":22348,"name":"Zuul","username":"zuul","tags":["SERVICE_USER"]}},{"label":"Code-Review","status":"MAY","applied_by":{"_account_id":7847,"name":"Alistair Coles","email":"alistairncoles@gmail.com","username":"acoles"}},{"label":"Workflow","status":"MAY","applied_by":{"_account_id":15343,"name":"Tim Burke","email":"tburke@nvidia.com","username":"tburke"}}]}],"submit_requirements":[{"name":"Verified","description":"Verified in gate by CI","status":"SATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Verified\u003dMAX AND -label:Verified\u003dMIN","fulfilled":true,"status":"PASS","passing_atoms":["label:Verified\u003dMAX"],"failing_atoms":["label:Verified\u003dMIN"],"atom_explanations":{"label:Verified\u003dMAX":"","label:Verified\u003dMIN":""}}},{"name":"Code-Review","description":"Code reviewed by core reviewer","status":"SATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Code-Review\u003dMAX AND -label:Code-Review\u003dMIN","fulfilled":true,"status":"PASS","passing_atoms":["label:Code-Review\u003dMAX"],"failing_atoms":["label:Code-Review\u003dMIN"],"atom_explanations":{"label:Code-Review\u003dMAX":"","label:Code-Review\u003dMIN":""}}},{"name":"Workflow","description":"Approved for gate by core reviewer","status":"SATISFIED","is_legacy":false,"submittability_expression_result":{"expression":"label:Workflow\u003dMAX AND -label:Workflow\u003dMIN","fulfilled":true,"status":"PASS","passing_atoms":["label:Workflow\u003dMAX"],"failing_atoms":["label:Workflow\u003dMIN"],"atom_explanations":{"label:Workflow\u003dMAX":"","label:Workflow\u003dMIN":""}}}]}
