DRIVERS-3598 : Summary of necessary driver changes Update the unified test runner to support schema 1.29. It adds the $$gte operator and applies ignoreExtraSpans at every level of the span tree. A runner capped at 1.28 rejects the new fixtures before matching begins: db.mongodb.cursor_ id: { $$ gte: 1 } Give each user-initiated getMore its own operation span, sibling to the cursor-creating operation's span. Driver-internal iteration adds no operation spans, no span is scoped to a cursor's lifetime, and a change stream resume ends the failed span while giving killCursors none. Drivers now MUST set db.mongodb.cursor_id on operation spans that create a cursor or operate on a single existing cursor. It is never a literal 0 , and for a getMore it holds the id the driver sent rather than the 0 the reply may return. Add spec tests from https://github.com/mongodb/specifications/commit/d1ac31b730d87c6cc18d126149da30008ef12561 and implement prose tests 3 and 4. Commits for syncing spec/prose tests https://github.com/mongodb/specifications/commit/d1ac31b730d87c6cc18d126149da30008ef12561 adds the two get_more fixtures, valid-pass/operator-gte as the reference test for the new operator, and prose tests 3 and 4. https://github.com/mongodb/mongo-python-driver/pull/2994 is the Python driver implementation. Context for other referenced/linked tickets DRIVERS-3627 tracks optional span links between the sibling getMore and cursor-creating operation spans. DRIVERS-3626 fixed MongoDB 4.2 server orchestration. Earlier patch runs for this ticket show two unrelated failures.
