Tests touching this area

Yes: see Current tests

Affected contract

LocalNetworkGamer::EnableSendVoice, LocalNetworkGamer::SendPartyInvites, NetworkMachine::RemoveFromSession, NetworkSession leaderboard/TrueSkill events, QualityOfService

Expected behaviour

XNA provides voice between gamers, party invites, host-side removal of a machine, arbitrated-leaderboard and TrueSkill write events, and measured bandwidth.

Actual behaviour at TARGET

LocalNetworkGamer.cpp: EnableSendVoice and SendPartyInvites have empty bodies. NetworkMachine.cpp: RemoveFromSession throws NotImplementedException. NetworkSession.hpp declares WriteArbitratedLeaderboard, WriteUnarbitratedLeaderboard and WriteTrueSkill “for API parity; never raised”. QualityOfService.cpp constructs results from round-trip time only; the BytesPerSecond* fields are never assigned.

Source locations

• modules/net/src/Xna/LocalNetworkGamer.cpp — EnableSendVoice and SendPartyInvites: empty
• modules/net/src/Xna/NetworkMachine.cpp — RemoveFromSession throws NotImplementedException
• modules/net/include/Microsoft/Xna/Framework/Net/NetworkSession.hpp — events declared for parity, never raised
• modules/net/src/Xna/QualityOfService.cpp — bandwidth fields never set

Evidence

Checked by reading at 009d40f5; not executed.

Independent re-verification: Checked by reading at 009d40f5; not executed. The stubs are pinned by tests: LocalNetworkGamerTest.EnableSendVoiceAndSendPartyInvitesAreNoOps, NetworkMachineTest.RemoveFromSessionThrows, the zero bytes-per-second assertions in AvailableNetworkSessionTests.cpp and NetworkSessionTest.WriteLeaderboardAndTrueSkillEventsAreNeverRaised, so an implementation has to change those tests. No test exercises a working version of any of the five features.

Focused reproduction

No focused reproduction is known. Nothing has been invented here; the evidence above is what exists.

Current tests

None for the missing features.

Regression test

Per feature, when implemented.

Blast radius

Games that use voice, kick players or read bandwidth; RemoveFromSession throws.

Workaround

Kick players with a game-level message; avoid RemoveFromSession.
