Browser Document Offline Sync via Abandoned Instance Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current browser technologies face challenges in version control, particularly in offline scenarios, where merging changes made by multiple users to the same document across different browser windows is difficult or impossible without human intervention, leading to issues like duplicate changes and delayed syncing.
Innovation Solution
A method for synchronizing browser documents that automatically determines when a document instance is abandoned, merges changes from abandoned instances into active ones, and syncs changes with a version control server, allowing seamless transition between online and offline modes without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If basic offline functionality is provided in browsers, then users can view past work and continue working on open documents offline, but versioning problems occur and changes cannot be automatically merged when reconnecting
Solution Approach 1:
The system performs preliminary actions by automatically detecting abandoned browser windows and merging their changes into active windows before the user reconnects to the server. This preliminary merging of changes ensures that when connectivity is restored, all changes are already integrated, eliminating versioning conflicts and ensuring reliable version control without requiring manual user intervention.
2Productivity
If multiple users independently make substantial changes to documents while disconnected, then productivity is maintained, but the remote server and browsers are unable to merge changes automatically without involving users
Solution Approach 1:
The system implements self-service by automatically detecting when a browser window is abandoned (closed without saving) and autonomously merging its changes into other active windows. This self-service mechanism eliminates the need for manual user intervention to resolve versioning conflicts, enabling automatic merging of changes made by multiple users while maintaining continuous productivity.
Solution Approach 2:
The system performs preliminary actions by automatically detecting abandoned browser windows and merging their changes into active windows before the user reconnects to the server. This preliminary merging of changes ensures that when connectivity is restored, all changes are already integrated, eliminating versioning conflicts and ensuring reliable version control without requiring manual user intervention.
3Productivity
If local editing is allowed while offline, then user productivity is maintained, but managing synchronization back to the remote server is difficult and may waste bandwidth and CPU cycles
Solution Approach 1:
The system extracts and processes only the necessary synchronization information by automatically detecting abandoned windows and merging their changes locally before synchronization. This extraction of critical change data allows the system to maintain offline productivity while preparing efficient synchronization packets that minimize unnecessary bandwidth and CPU cycle consumption during server communication.

AI summary
In an embodiment, a method for synchronizing browser documents is described. The method may include losing a connection to a version control server at a client device having first and second instances of a document open in first and second browser windows of a browser. The method may also include storing a first branch corresponding to the first instance of the document in local storage associated with the first browser. The first branch may indicate whether the first instance of the document is open or abandoned and one or more first changes. The method may also include the second browser window automatically determining that the first instance of the document is abandoned. The method may also include the second browser window automatically merging the one or more first changes into the second instance of the document in response to determining that the first instance of the document is abandoned.
