This PR builds on the centralized transient support and extends the LF federated runtime to support transient federates under decentralized coordination, where all connections are P2P and no RTI message
forwarding occurs. It also adds support for physical connections involving transient federates under centralized coordination, which are P2P connections.
Companion PR in
reactor-c: #574LF compiler (
lingua-franca)Code generation (
CExtension.java)lf_connect_to_federate()now takes an additionalis_transientparameter. The difference in behavior is documented in the companion PR.inbound_p2p_connection_is_transient[NUMBER_OF_FEDERATES]andoutbound_p2p_connection_is_transient[NUMBER_OF_FEDERATES], so the runtime can track which outbound peers are transient.Tests
All transient tests are under
test/C/src/federated/transient/. New tests:DecentralizedTransientDownstreamWithTimer.lf— transient upstream, persistent outbound, decentralized coordination.DecentralizedTransientDownstreamWithTwoUpstream.lf— transient with two inbound federates (one persistent, one transient), authenticated.DecentralizedTransientStatePersistence.lf— verifies that state is correctly carried across re-joins.DecentralizedTransientHotSwap.lf— hot-swap of a transient federate under decentralized coordination.DecentralizedTransientWithPhysicalConnection.lfTransientWithPhysicalConnection.lfPossible future improvements
