Automatic Marshalling for Cross-Thread Method Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-threaded runtime environments, efficiently handling method calls between threads is cumbersome due to the need for manual marshalling, which increases the risk of errors if not implemented correctly, especially when the number of methods requiring marshalling is large.
Innovation Solution
A method for compiling source code into object code that identifies and rewrites marshalling attributes associated with method code intended for execution in a secondary thread, allowing for automatic marshalling during the compilation process, thereby simplifying the threading requirements and reducing the risk of errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual marshalling code is added to each method, then thread safety is ensured, but device complexity and programming burden increase
Solution Approach 1:
The marshalling logic is performed in advance during the compilation process rather than at runtime. The compiler automatically generates the necessary marshalling code before the program executes, so that when the program runs, only simple method calls are needed without complex thread-checking logic.
Solution Approach 2:
The compilation system automatically performs the marshalling task without requiring manual intervention from the programmer. The compiler detects when marshalling is needed and automatically generates the appropriate code, making the system self-sufficient and eliminating the need for developers to manually implement thread-safe marshalling logic.
2Reliability
If manual marshalling is implemented, then thread interaction is controlled, but ease of operation deteriorates due to syntax errors and programming burden
Solution Approach 1:
The compiler automatically handles thread interaction control by detecting marshalling requirements and generating appropriate code. Developers simply write their business logic without needing to manually implement thread-safe marshalling, significantly improving ease of operation while maintaining reliable thread interaction control.
Solution Approach 2:
The manual mechanical process of writing and verifying marshalling code is replaced by an automated compilation process. Instead of developers manually writing and checking marshalling syntax, the compiler automatically performs this mechanical task, eliminating syntax errors and reducing programming burden.
3Stability of the object's composition
If synchronous marshalling is used, then data consistency is ensured, but productivity decreases due to waiting for method completion
Solution Approach 1:
The system dynamically adapts the marshalling behavior based on the specific requirements of each method call. Instead of forcing synchronous marshalling for all calls, the compiler allows asynchronous marshalling when appropriate, enabling the program to switch between synchronous and asynchronous modes depending on the operational context and performance needs.
Data Source
AI summary
A method of compiling source code into object code for a multi-threaded runtime environment is disclosed. Source code is compiled into object code using a compilation engine. Marshalling attributes associated with method code intended for executing in a secondary thread are identified. The marshalling attributes and the method code are rewritten as marshaled method code for executing the method code in the secondary thread according to the identified marshalling attributes.
