EMULATING TRANSPARENT FILE PROCESSING

摘要

Transparent file processing is supported in Unix-like operating systems by emulating the desired file processing through a number of recipes that accommodate different contexts. Recipes are provided, for example, for local folders in user space, for whole devices (e.g., flash drives or network drives), and for folders synchronized to cloud data. By detecting the path type for a file operation and selecting and applying the appropriate recipe, file processing can be performed in a manner transparent to the user.

主权项

1. A method for emulating transparent file processing comprising:
receiving a file operation for a file, the file operation being a user-space file operation specifying a label for a volume and a path specifying a unique location in a file system on the volume; determining a type for the path, wherein the type is selected from a group consisting of an existing folder in the file system, a physical device, and a synchronized folder for a remote service; selecting a recipe for executing the file operation based upon the type, thereby providing a selected recipe, wherein the selected recipe includes overmounting when the type includes the existing folder, remounting when the type includes the physical device, and creating a new label when the type includes a synchronized folder; and executing the file operation on the file with the selected recipe transparently to a user process that initiated the file operation.
