Proxy Object for Interactive REPL Session Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a read-eval-print loop (REPL) environment, user interactions with a server are disjointed and asynchronous, limiting the ability to iteratively and interactively process commands, as clients typically send batch commands and receive disjointed results without maintaining a continuous execution context.
Innovation Solution
A client computer system receives a proxy object from a remotely-hosted server, allowing users to interact with and manipulate remotely-hosted data through a local interface, sending user-initiated commands and displaying processed data, while the server maintains a running execution context for iterative operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the client sends batch commands to the server in traditional REPL environment, then the server can process commands, but the user interactions become disjointed and asynchronous
Solution Approach 1:
The patent introduces a session object as an intermediary between the client and server. This session object maintains the execution context and state information, allowing the client to interact with the server in a continuous, synchronous manner while the server processes commands in batches. The session object acts as a mediator that bridges the disconnect between batch processing and interactive user experience.
Solution Approach 2:
The server performs preliminary actions by maintaining the execution context and state information in advance. Instead of creating and tearing down the processing context for each command, the server prepares and sustains the execution environment beforehand, allowing for continuous interactive operations without repeated setup overhead.
2Loss of energy
If the server creates and tears down processing context for each command batch, then resource usage is controlled, but the user experience becomes disjointed
Solution Approach 1:
The patent implements continuity of useful action by maintaining the execution context across multiple command batches. The server keeps the processing context alive and updates it incrementally as commands are processed, rather than creating and destroying it repeatedly. This continuous maintenance of state information enables smooth interactive operations while avoiding the overhead of repeated context initialization.
Solution Approach 2:
The execution context is created preliminarily and maintained for the duration of the interactive session. This preliminary action eliminates the need for repeated context creation and teardown, reducing resource overhead while enabling continuous interaction.
3Speed
If the client maintains local copy of remotely-hosted data, then access speed improves, but data synchronization and consistency become problematic
Solution Approach 1:
The session object serves as an intermediary that manages the relationship between local and remote data. It maintains references to remotely-hosted data objects and coordinates access, allowing fast local access while ensuring consistency with the remote server through centralized state management.
Solution Approach 2:
The patent uses lightweight proxy objects that copy only the essential interface and state references, not the entire data set. These proxy objects provide fast local access to remotely-hosted data while maintaining references to the authoritative remote sources, ensuring consistency without requiring full data duplication.
Data Source
AI summary
Embodiments are directed to interacting with a server in a read-eval-print loop (REPL) environment. In an embodiment, a client computer system receives a proxy object from a remotely-hosted server. The server maintains an execution context with which the client computer system interacts. The client system presents the received proxy object to the user for interaction with the object. The user input indicates how the data in the proxy object is to be processed. The interaction allows the user to manipulate the remotely-hosted data through the local computer system. The client system then, based on the user interaction, sends a user-initiated command to the remotely-hosted server using the proxy object. The user-initiated command indicates various portions of data hosted on the server that are to be returned to the user. The data received from the remotely-hosted server is then displayed at the client computer system.
