Abstract

A server computer system receives a request for access to an object in a file system. The object is a file or a directory. The server computer system identifies an object handle in the request. The object handle is an identifier of the object. The server computer system identifies an object link that is associated with the object handle. The object link is a hard link to the file or a relative symbolic link to the directory. The server computer system accesses the object using the object link that is associated with the object handle.

Claims

1. A method, comprising:

receiving, by a processing device, a request to access an object in a file system, the request comprising an identifier of the object, wherein the object is a file or a directory;

identifying, in view of the identifier of the object, an object link, wherein the object link is a relative symbolic link to the directory; and

accessing the object using the object link.

3. The method of claim 1, wherein the object is the directory and the method further comprises:

creating a directory handle for the directory;

creating the relative symbolic link that corresponds to the directory handle; and

storing the relative symbolic link in a hidden directory in the file system.

6. The method of claim 1, wherein the object link comprises at least one of a hidden directory in the file system or one or more sub-directories.

7. The method of claim 1, wherein the object is the file and the method further comprises:

receiving a request for a link count for the file; and

providing the link count value.

5. (canceled)

8. A non-transitory computer-readable storage medium including instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

Receiving, by the processing device, a request to access an object in a file system, the request comprising an identifier of the object, wherein the object is a file or a directory;

Identifying, by the processing device, in view of the identifier of the object, an object link, wherein the object link is a relative symbolic link to the directory; and

Accessing, by the processing device, the object using the object link.

10. The non-transitory computer-readable storage medium of claim 8, wherein the object is the directory and the set of operations further comprise:

creating a directory handle for the directory;

creating the relative symbolic link that corresponds to the directory handle; and

storing the relative symbolic link in a hidden directory in the file system.

13. The non-transitory computer-readable storage medium of claim 8, wherein the object link comprises at least one of a hidden directory in the file system or one or more sub-directories.

14. The non-transitory computer-readable storage medium of claim 8, wherein the object is the file and the operations further comprise:

receiving a request for a link count for the file; and

providing the link count value.

15. A system comprising:

a memory; and

a processing device coupled to the memory to;

receive a request to access an object in a file system, the request comprising an identifier of the object, wherein the object is a file or a directory;

identify, in view of the identifier of the object, an object link, wherein the object link is a relative symbolic link to the directory; and

access the object using the object link.

16. The system of claim 15, wherein the object is the file and the processing device is further to:

create a file handle for the file;

create the hard link that corresponds to the file handle; and

store the hard link in a hidden directory in the file system.

17. The system of claim 15, wherein the object is the directory and the processing device is further to:

create a directory handle for the directory;

create the relative symbolic link that corresponds to the directory handle; and

store the relative symbolic link in a hidden directory in the file system.

20. The system of claim 15, wherein the object is the file and the processing device is further to:

receive a request for a link count for the file; and

provide the link count value.
