Abstract

Executing a plugin includes obtaining a stability level of the plugin to be executed, determining a plugin execution mode based at least in part on the stability level, and executing the plugin according to the plugin execution mode determined. The plugin execution mode is selected from a plurality of available plugin execution modes.

Claims

1. A method for executing a plugin, comprising:

obtaining a stability level of the plugin to be executed;

determining a plugin execution mode based at least in part on the stability level, the plugin execution mode being selected from a plurality of available plugin execution modes; and

executing the plugin according to the plugin execution mode determined.

2. The method of claim 1, wherein the stability level of the plugin is obtained from a storage location.

3. The method of claim 1, wherein the plurality of plugin execution modes correspond to a plurality of available plugin stability levels.

4. The method of claim 1, wherein:

the plurality of plugin execution modes correspond to a plurality of loader processes; and

executing the plugin according to the plugin execution mode determined includes starting a loader process among the plurality of loader processes that corresponds to the plugin execution mode determined to load the plugin.

5. The method of claim 4, wherein in the event that the stability level of the plugin is stable, the loader process is a shared loader process.

6. The method of claim 4, wherein in the event that the stability level of the plugin is ordinary, the loader process is an independent loader process.

7. The method of claim 4, wherein in the event that the stability level of the plugin is unstable, the method further comprising aborting execution of the plugin.

8. The method of claim 4, wherein in the event that the stability level of the plugin is unstable, the method further comprising obtaining and saving the abnormality information of the plugin.

9. The method of claim 8, wherein the abnormality information comprises reason for abnormal behavior of the plugin and plugin information of the plugin.

10. The method of claim 1, further comprising adjusting the stability level of the plugin.

11. The method of claim 10, wherein adjusting the stability level of the plugin comprises:

determining a number of times the plugin behaved abnormally during a given amount of time; and

adjusting the stability level of the plugin based at least in part on the determination of the number of times the plugin behaved abnormally during a given amount of time.

12. A system for executing a plugin, comprising:

one or more processors configured to;

obtain a stability level of the plugin to be executed;

determine a plugin execution mode based at least in part on the stability level, the plugin execution mode being selected from a plurality of available plugin execution modes; and

execute the plugin according to the plugin execution mode determined; and

one or more memories coupled to the one or more processors, configured to provide the one or more processors with instructions.

13. The system of claim 12, wherein the stability level of the plugin is obtained from a storage location.

14. The system of claim 12, wherein the plurality of plugin execution modes correspond to a plurality of available plugin stability levels.

15. The system of claim 12, wherein:

the plurality of plugin execution modes correspond to a plurality of loader processes; and

executing the plugin according to the plugin execution mode determined includes starting a loader process among the plurality of loader processes that corresponds to the plugin execution mode determined to load the plugin.

16. The system of claim 15, wherein in the event that the stability level of the plugin is stable, the loader process is a shared loader process.

17. The system of claim 15, wherein in the event that the stability level of the plugin is ordinary, the loader process is an independent loader process.

18. The system of claim 15, wherein in the event that the stability level of the plugin is unstable, the one or more processors are further configured to abort execution of the plugin.

19. The system of claim 15, wherein in the event that the stability level of the plugin is unstable, the one or more processors are further configured to obtain and save the abnormality information of the plugin.

20. The system of claim 12, wherein the one or more processors are further configured to adjust the stability level of the plugin.

21. The system of claim 20, wherein adjusting the stability level of the plugin comprises:

determining a number of times the plugin behaved abnormally during a given amount of time; and

adjusting the stability level of the plugin based at least in part on the determination of the number of times the plugin behaved abnormally during a given amount of time.

22. A computer program product for executing a plugin, the computer program product being embodied in a computer readable storage medium and comprising computer instructions for:

obtaining a stability level of the plugin to be executed;

determining a plugin execution mode based at least in part on the stability level, the plugin execution mode being selected from a plurality of available plugin execution modes; and

executing the plugin according to the plugin execution mode determined.
