Cache Server File Locking for Web IDE Conflict Prevention

The patent introduces a file locking mechanism that acts as an intermediary between multiple developers and the file being edited. When a developer opens a file for editing, the system creates a lock record in the cache server that prevents other developers from simultaneously writing to the same file. This mediator (locking mechanism) coordinates access without requiring developers to manually negotiate, thus maintaining collaborative flexibility while ensuring file content consistency.

The patent introduces a cache server as an intermediary layer between the client terminal and the file system. The cache server stores file locking information and operation data, acting as a mediator that enforces permission control policies. This allows the client terminal to operate efficiently with cached data while the cache server maintains security by validating permissions and controlling access rights, thus resolving the conflict between operational speed and security control.

The patent implements a dual-storage strategy where modification contents are simultaneously maintained in both the client terminal cache and the cache server. The cache server stores copies of operation data and file states, creating a redundant backup system. This allows fast local operations while ensuring data persistence, as modifications can be recovered from the cache server copy if the client terminal is switched or data is lost locally.

The patent implements a feedback mechanism where the cache server continuously monitors and validates operations on cached data. When developers attempt to modify cached data, the system checks permission records and operation legitimacy before allowing changes. This feedback loop maintains security by preventing unauthorized modifications while preserving operational flexibility for legitimate actions, as the system responds to each operation with appropriate permission verification.
