Automatic application error detection and rollback

1. A computer-implemented method comprising:

managing access to at least two versions of an application, the at least two versions comprising a previous version and a new version, wherein access to the previous version includes a previous version uniform resource locator (URL) and access to the new version includes a new version URL;

providing the new version URL to a plurality of clients;

receiving error information of the new version of the application for at least one individual client of the plurality of clients; and

changing, for the at least one individual client, the new version URL to the previous version URL, based on the error information.

2. The method of claim 1 , wherein changing the new version URL to the previous version URL comprises providing an updated extensible markup language (XML) representation to the at least one individual client, wherein the updated XML representation includes the previous version URL.

3. The method of claim 1 , wherein changing the new version URL to the previous version URL comprises changing, in a structured data resource, an entry for an account of the one individual client from the new version URL to the previous version URL.

4. The method of claim 1 , wherein the changing the new version URL to the previous version URL is performed in response to receiving a request to access or run the application specified by the new version URL.

5. The method of claim 1 , further comprising:

receiving a full version of the new version of the application, the full version including logic, graphics, and functionality of the application;

storing the full version of the new version of the application; and

generating the new version URL.

6. The method of claim 1 , further comprising:

receiving an extensible markup language (XML) representation of the new version of the application, the XML representation comprising the new version URL.

7. The method of claim 1 , wherein the error information comprises one or more of an error signal, error logs, error information from debuggers, changes in usage data, and performance data.

8. The method of claim 1 , wherein receiving error information of the new version comprises:

receiving the error information from the at least one individual client; and

analyzing the error information.

9. The method of claim 1 , wherein receiving error information of the new version comprises receiving the error information from a telemetry service.

10. One or more computer readable storage media having instructions stored thereon that, when executed by a computing system, direct the computing system to:

provide a new version uniform resource locator (URL) to a client, the new version URL providing access to a new version of an application;

receive error information of the new version of the application for at least one individual client of a plurality of clients accessing the new version of the application via the new version URL; and

change, for the at least one individual client, the new version URL to a previous version URL, based on the error information.

11. The media of claim 10 , wherein the instructions that direct the computing system to change the new version URL to the previous version URL direct the computing system to:

provide an updated extensible markup language (XML) representation to the at least one individual client, wherein the updated XML representation includes the previous version URL.

12. The media of claim 10 , wherein the instructions that direct the computing system to change the new version URL to the previous version URL direct the computing system to:

change, in a structured data resource, an entry for an account of the one individual client from the new version URL to the previous version URL.

13. The media of claim 10 , wherein the instructions that direct the computing system to change the new version URL to the previous version URL direct the computing system to:

change the new version URL to the previous version URL in response to receiving a request to access or run the application specified by the new version URL.

14. The media of claim 10 , further comprising instructions stored thereon that, when executed by the computing system, direct the computing system to further:

in response to receiving a full version of the new version of the application, store the full version of the new version of the application and generate the new version URL; and

in response to receiving an extensible markup language (XML) representation of the new version of the application, store the XML representation, wherein the XML representation comprises the new version URL.

15. The media of claim 10 , further comprising instructions stored there that, when executed by the computing system, direct the computing system to provide a telemetry service that at least receives the error information from the at least one individual client; and analyzes the error information.

16. A system comprising:

a processing system;

a storage system; and

an automatic application error detection and rollback service stored on the storage system that, when executed by the processing system, directs the processing system to:

manage access to at least two versions of an application, the at least two versions comprising a previous version and a new version, wherein access to the previous version includes a previous version uniform resource locator (URL) and access to the new version includes a new version URL;

provide the new version URL to a plurality of clients;

receive error information of the new version of the application for at least one individual client; and

change, for the at least one individual client, the new version URL to the previous version URL, based on the error information.

17. The system of claim 16 , wherein to manage access to at least two versions of the application, the service directs the processing system to:

store at least the previous version URL and the new version URL at the storage system; and

store account information for the plurality of clients.

18. The system of claim 16 , wherein to change the new version URL to the previous version URL, the service directs the computing system to:

provide an updated extensible markup language (XML) representation to the at least one individual client, wherein the updated XML representation includes the previous version URL.

19. The system of claim 16 , further comprising structured data stored at the storage system, the structured data comprising at least account information for the plurality of clients,

wherein to change the new version URL to the previous version URL, the service directs the computing system to:

change, at the storage system, an entry for an account of the one individual client from the new version URL to the previous version URL.

20. The system of claim 16 , wherein to change the new version URL to the previous version URL, the service directs the computing system to:

change the new version URL to the previous version URL in response to receiving a request to access or run the application specified by the new version URL.
