Abstract

A method includes transmitting, from a computing device to one or more server computers, an update request corresponding to a client-side application package that is stored at the computing device. The client side application package contains a plurality of application components. The method also includes receiving a differential update package in response to the request. The differential update package includes a plurality of deltas, wherein each delta corresponds to one of the application components contained in the client side application package. The method also includes applying the plurality of deltas to modify at least some of the application components from the plurality of application components.

Claims

1. A method, comprising:

transmitting, from a computing device to one or more server computers, an update request corresponding to a client-side application package that is stored at the computing device, the client side application package contains a plurality of application components;

receiving a differential update package in response to the request, the differential update package including a plurality of deltas, wherein each delta corresponds to one of the application components contained in the client side application package; and

applying the plurality of deltas to modify at least some of the application components from the plurality of application components.

2. The method of claim 1, further comprising:

unpacking the client side application package, prior to applying the plurality of deltas, such that the plurality of application components of the client-side application package can be modified.

3. The method of claim 2, further comprising:

generating an updated client-side application package by re-packaging the plurality of application components subsequent to applying the plurality of deltas.

4. The method of claim 1, wherein the update request includes a signature corresponding to the client-side application package.

5. The method of claim 4, wherein the differential update package is selected by the one or more server computers using the signature.

6. The method of claim 5, wherein the signature is a hash code.

7. The method of claim 1, wherein the client side application package is equivalent to a first server-side application package located at the one or more server computers, the updated client-side application package is equivalent to a second server-side application package located at the one or more server computers, and the differential update package is generated by the one or more server computers using the first server-side application package and the second server side application package.

8. A storage medium including program instructions executable by one or more processors that, when executed, cause the one or more processors to perform operations, the operations comprising:

transmitting, from a computing device to one or more server computers, an update request corresponding to a client-side application package that is stored at the computing device, the client side application package contains a plurality of application components;

receiving a differential update package in response to the request, the differential update package including a plurality of deltas, wherein each delta corresponds to one of the application components contained in the client side application package; and

applying the plurality of deltas to modify at least some of the application components from the plurality of application components.

9. The storage medium of claim 8, further comprising:

unpacking the client side application package, prior to applying the plurality of deltas, such that the plurality of application components of the client-side application package can be modified.

10. The storage medium of claim 9, further comprising:

generating an updated client-side application package by re-packaging the plurality of application components subsequent to applying the plurality of deltas.

11. The storage medium of claim 8, wherein the update request includes a signature corresponding to the client-side application package.

12. The storage medium of claim 11, wherein the differential update package is selected by the one or more server computers using the signature.

13. The storage medium of claim 12, wherein the signature is a hash code.

14. The storage medium of claim 8, wherein the client side application package is equivalent to a first server-side application package located at the one or more server computers, the updated client-side application package is equivalent to a second server-side application package located at the one or more server computers, and the differential update package is generated by the one or more server computers using the first server-side application package and the second server side application package.

15. An apparatus, comprising:

one or more processors; and

one or more memory devices for storing program instructions used by the one or more processors, wherein the program instructions, when executed by the one or more processors, cause the one or more processors to;

transmit, from a computing device to one or more server computers, an update request corresponding to a client-side application package that is stored at the computing device, the client side application package contains a plurality of application components;

receive a differential update package in response to the request, the differential update package including a plurality of deltas, wherein each delta corresponds to one of the application components contained in the client side application package; and

apply the plurality of deltas to modify at least some of the application components from the plurality of application components.

16. The apparatus of claim 15, wherein the program instruction further cause the one or more processors to:

unpack the client side application package, prior to applying the plurality of deltas, such that the plurality of application components of the client-side application package can be modified.

17. The apparatus of claim 16, wherein the program instruction further cause the one or more processors to:

generate an updated client-side application package by re-packaging the plurality of application components subsequent to applying the plurality of deltas.

18. The apparatus of claim 15, wherein the update request includes a signature corresponding to the client-side application package.

19. The apparatus of claim 18, wherein the differential update package is selected by the one or more server computers using the signature.

20. The apparatus of claim 19, wherein the signature is a hash code.

21. The apparatus of claim 15, wherein the client side application package is equivalent to a first server-side application package located at the one or more server computers, the updated client-side application package is equivalent to a second server-side application package located at the one or more server computers, and the differential update package is generated by the one or more server computers using the first server-side application package and the second server side application package.
