Abstract

An apparatus and a method for accessing data from a server. In one embodiment, data referred by a Universal Resource Identifier (URI) is mounted on a file system. The mounted data can then be operated on using the file system. To mount the data referred by the URI, a Uniform Resource Locator (URL) fragment of the URI is determined. An identifier on the file system is generated based on the URL fragment. Data referred by the URI is mapped to the file system using the identifier.

Claims

1. A method comprising:

receiving, by a processing device, an instruction to mount a file system with data from a storage;

determining a plurality of Universal Resource Identifiers (URIs) to be accessible on the mounted file system in response to the instruction;

generating a plurality of identifiers corresponding to file names on the file system in view of locations of a plurality of data items referred by the plurality of URIs;

mounting, by the processing device, the file system with the plurality of data items referred by the plurality of URIs, wherein the mounting comprises mapping the plurality of data items referred by the plurality of URIs to the plurality of identifiers corresponding to file names on the file system; and

receiving an instruction to access at least one of the plurality of data items via the mounted file system.

2. The method of claim 1, wherein mapping the plurality of data items referred by the plurality of URIs comprises mangling at least one of the plurality of URIs and generating at least one of the plurality of identifiers in view of the mangled at least one of the plurality of URIs.

3. The method of claim 1, wherein mapping the plurality of data items referred by the plurality of URIs comprises converting at least one of the plurality of URIs into at least one of the plurality of identifiers of the file system using a table lookup.

4. The method of claim 1, wherein mapping the plurality of data items referred by the plurality of URIs comprises converting at least one of the plurality of URIs into at least one of the plurality of identifiers of the file system with a conversion algorithm.

5. The method of claim 1, wherein mapping the plurality of data items referred by the plurality of URIs comprises determining a fragment of at least one of the plurality of URIs and generating at least one of the plurality of identifiers by directly using the fragment.

6. The method of claim 1, wherein at least one of the plurality of identifiers has a name and represents a data item referred by the URI as one of a real file, a named pipe, a named socket or a symbolic link.

7. The method of claim 1, further comprising receiving a local directory location and wherein mapping the plurality of data items comprises mapping the plurality of data items referred by the plurality of URIs to a plurality of identifiers in the local directory location on the file system.

8. An apparatus comprising:

a memory; and

a processing device operatively coupled to the memory, wherein the processing device is to;

receive an instruction to mount a file system with data from a storage;

determine a plurality of Universal Resource Identifiers (URIs) to be accessible on the mounted file system in response to the instruction;

generate a plurality of identifiers corresponding to file names on the file system in view of locations of a plurality of data items referred by the plurality of URIs;

mount the file system with the plurality of data items referred by the plurality of URIs, wherein the mounting comprises mapping the plurality of data items referred by the plurality of URIs to the plurality of identifiers corresponding to file names on the file system; and

receive an instruction to access at least one of the plurality of data items via the file system.

9. The apparatus of claim 8, wherein the processing device is further to mangle at least one of the plurality of URIs and generate at least one of the plurality of identifiers in view of the mangled at least one of the plurality of URIs.

10. The apparatus of claim 8, wherein the processing device is to map the plurality of data items referred by the plurality of URIs by converting at least one of the one or more URIs into at least one of the plurality of identifiers on the file system using a table lookup.

11. The apparatus of claim 8, wherein the processing device is to map the plurality of data items referred by the plurality of URIs by converting at least one of the plurality of URIs into at least one of the plurality of identifiers with a conversion algorithm.

12. The apparatus of claim 8, wherein the processing device is to map the plurality of data items referred by the plurality of URIs by determining a fragment of at least one of the plurality of URIs and generating at least one of the plurality of identifiers by directly using the fragment.

13. The apparatus of claim 8, wherein at least one of the plurality of identifiers has a name and represents a data item referred by the URI as one of a real file, a named pipe, a named socket or a symbolic link.

14. A non-transitory computer-readable medium having instructions encoded thereon that, when executed by a processing device, cause the processing device to:

receive, by the processing device, an instruction to mount a file system with data from a storage;

determine a plurality of Universal Resource Identifiers (URIs) to be accessible on the mounted file system in response to the instruction;

generate a plurality of identifiers corresponding to file names on the file system in view of locations of a plurality of data items referred by the plurality of URIs;

mount, by the processing device, the file system with the plurality of data items referred by the plurality of URIs, wherein the mounting comprises mapping the plurality of data items referred by the plurality of URIs to the plurality of identifiers corresponding to file names on the file system; and

receive an instruction to access at least one of the plurality of data items via the mounted file system.

15. The non-transitory computer-readable medium of claim 14, wherein to map the plurality of data items referred by the plurality of URIs, the processing device is to mangle at least one of the plurality of URIs and generate at least one of the plurality of identifiers in view of the mangled at least one of the plurality of URIs.

16. The non-transitory computer-readable medium of claim 14, wherein to map the plurality of data items referred by the plurality of URIs, the processing device is to convert at least one of the plurality of URIs into at least one of the plurality of identifiers using a table lookup or a conversion algorithm.

17. The non-transitory computer-readable medium of claim 14, wherein to map the plurality of data items referred by the plurality of URIs, the processing device is to determine a fragment of at least one of the plurality of URIs and generate at least one of the plurality of identifiers on the file system by directly using the fragment.

18. The non-transitory computer-readable medium of claim 14, wherein at least one of the plurality of identifiers has a name and represents a data item referred by the URI as one of a real file, a named pipe, a named socket or a symbolic link.
