What
Extends the annotation-driven message codegen (previously serialization-only) to
marshalling and deployment: a message's wire read/write, marshalling and
deployment are now generated from declarative field annotations, replacing
hand-written writeTo/readFrom, prepareMarshal/finishUnmarshal and prepareDeployment.
Main directions
Generated marshaller & deployer companions.
MessageProcessornow emits<Msg>Marshallerand<Msg>Deployernext to<Msg>Serializer, driven by@Marshalled/@MarshalledCollection/@MarshalledMap(with@Order/@NioField). Hand-written marshalling/deployment hooks are removed from messages.Uniform factory dispatch.
MessageFactoryresolves all three by direct type —serializer()/marshaller()/deployer()— via oneregister(directType, supplier, serializer, marshaller, deployer). Callers use thestatic facades
MessageSerializer.writeTo/readFrom,MessageMarshaller.marshal/unmarshal,GridCacheMessageDeployer.deploy; an ArchUnit rule (MessageSerializationArchitectureTest)enforces it.
Comm & discovery wired to it.
GridIoManager/GridCacheIoManager/IgniteTxManagerand the TCP/ZK discovery I/O callMessageMarshaller.marshal/unmarshal;discovery custom messages (
MetadataUpdateProposedMessage,BinaryMetadataVersionInfo, …)move from
MarshallableMessagehooks to@Marshalled.Deployment collapsed.
GridCacheMessageDeployeris now only the codegen interfaceplus the factory-resolving facade; per-field static bridges dropped,
GridCacheMessage#deploy*accessed directly.
Marshalling stays off the NIO threads. The NIO codec does only serialization
(
writeTo/readFrom); the actual marshal/unmarshal runs on the sender and workerthreads.
@NioField+unmarshalNioare the explicit, minimal exception — only thehandful of fields needed for early dispatch are unmarshalled on the NIO thread.
Side effects (mechanical — skim)
prepareMarshal→marshal,finishUnmarshal→unmarshal,finishUnmarshalNio→unmarshalNio(onMarshallableMessage/MessageMarshaller);CacheObject#prepareMarshal(ctx)/finishUnmarshal(ctx)→marshal/unmarshal;prepareDeployment+prepare*Deploymenthelpers →deploy/deploy*;MarshallerCacheFreeFinishTest→…UnmarshalTest,MessageFinishUnmarshalOnceTest→MessageUnmarshalOnceTest..mvn/jvm.configopensjdk.compilerfor the codegen tests(Google compile-testing);
commit-check.ymlnow surfaces the real compile errorbehind the generated-class "cannot find symbol" cascade.
Performance
JMH-verified: serialization hot path unchanged (Δ ≈ 0 vs master); marshalling adds
~1.8 ns/message of factory dispatch (<0.5% of the actual
U.marshal, ~µs); zero extraallocations.
