调研方向

Start by locating ContractInterface.beforeTransaction and SerializerInterface.toBuffer/fromBuffer, then inspect their implementations and tests. Trace how transaction parameters and Context are currently propagated; done means hooks and custom serializers can access the active Context and transaction inputs without ThreadLocal, with compatibility covered by tests.

描述

enhancement
Current Status

ContractInterface.beforeTransaction receives the active Context, but not the parameters passed to the transaction method. The SerializerInterface methods (toBuffer and fromBuffer) do not receive a Context.

This prevents hooks and custom serializers from directly accessing both the transaction context and its input data. For example, a custom serializer that needs to perform Jakarta Bean Validation during deserialization cannot access the current Context through the API. A workaround is to pass it through a ThreadLocal and a custom Context implementation, relying on the shim's current thread-per-request behavior.

Expected

Contract hooks and custom serializers should be able to access the active transaction Context. The hook should also be able to inspect the parameters intended for the transaction method.

This would allow developers to perform shared parameter validation, make context-dependent decisions, and implement context-aware serialization without relying on ThreadLocal.

Solution

Consider adding the transaction parameters to the hook:

default void beforeTransaction(final Context ctx, final Object... params)
