Abstract

Provided is a method for mitigating the effects of an application which crashes as the result of supplemental code (e.g., plug-in), particularly a plug-in from a source other than the source of the operating system of the device or the source of the application that crashes. The method includes executing the application. As the application is running, it may be monitored to determine if normal execution of instructions ceases. When that occurs, the system will make a determination if code from a supplemental code module was the cause of the crash, and will make an evaluation if that supplemental code module is from a source other than the source(s) of the operating system and application in question. In some implementations, remedial steps may be provided, such as providing information on subsequent executions of the application.

Claims

1. A machine-readable medium including a set of instructions which when implemented by a machine, cause operations to be performed, the operations comprising:

executing the application;

determining whether the application has crashed since its last execution because of a third party supplemental code module.

2. The machine-readable medium of claim 1, wherein said operations further comprise, if the determination is made that the application has crashed since its last execution because of a third party supplemental code module, taking an action with respect to the supplemental code module.

3. The machine-readable medium of claim 2, wherein the action taken with respect to the supplemental code module comprises disabling the supplemental code module.

4. A machine readable medium having a plurality of instructions, which when implemented by a machine, cause operations to be performed which comprise:

operations to perform the intended functionality of an application program, which application program is configured to utilize supplemental code; and

operations which interface with a monitoring system external to the application, comprising;

initiating a call to the monitoring system to request information regarding whether the application crashed during a prior instantiation as a result of supplemental code from a source different than a source of the application; and

providing a user interface to present information to a user regarding a prior crash, the information received in response to the initiated call.

5. A method comprising the acts of:

determining whether an application has crashed since its last execution because of a third party supplemental code module; and

selectively performing an action based on the determination, the action selected from the group consisting of uninstalling, disabling and loading the third party supplemental code module.

6. The method of claim 5, wherein the act of selectively performing further comprises the acts of:

presenting a user interface to a user identifying the third party supplemental code module which was responsible for crashing the application;

querying the user as to a selection of one of uninstalling, disabling and loading of the third party supplemental code module in response to the identification of the third party supplemental code module; and

receiving the user'"'"'s selection in response to the querying.

7. The method of claim 5, wherein the act of determining further comprises the act of:

retrieving a date and time associated with the last execution of the application;

retrieving a date and time associated with a most recent crash of the application; and

comparing the date and time of the most recent crash to the time and date of the last execution to determine whether the application has crashed since its last execution.

8. The method of claim 5, wherein the act of determining further comprises the acts of:

retrieving a supplemental code module name corresponding to a supplemental code module that has caused a most recent crash of the application; and

determining whether the supplemental code module is provided by a third party.

9. The method of claim 5, wherein the act of determining further comprises the acts of:

retrieving a supplemental code module name corresponding to a supplemental code module that has caused a most recent crash of the application;

determining whether the supplemental code module is provided by a third party;

retrieving a plurality of supplemental code module names corresponding to supplemental code modules that caused earlier crashes of the application; and

determining whether the name of the supplemental code module occurs a predetermined number of times in the plurality of supplemental code module names to determine a pattern of crashes caused by the supplemental code module.

10. The method of claim 5, the method further comprising the acts of:

retrieving a current date and time associated with the execution of the application; and

recording the current date and time for retrieval during a next execution of the application to determine whether the application crashed since its execution represented by the current date and time.

11. The method of claim 5, further comprising the act of generating a hint for a supplemental code module when the supplemental code module is loaded into the application, the hint identifying a developer of the supplemental code module and a descriptive name for the supplemental code module.

12. The method of claim 5, wherein the act of determining further comprises the act of detecting the crash of the application during its last execution.

13. The method of claim 12, further comprising the act of deciding whether the third party supplemental code module was a cause of the crash of the application during its last execution.

14. The method of claim 13, wherein the act of deciding further comprises the acts of:

identifying a recent frame in a plurality of frames, each of the frames representing an address of code executed by the application during its prior execution;

determining whether an address of the identified frame is within an address range of a code module in a plurality of code modules loaded by the application during the prior execution; and

determining whether an origin attribute of the code module is indicative of third party origin.

15. The method of claim 13, wherein the act of deciding further comprises the acts of:

obtaining a plurality of frames, each of said frames representing an address of code executed by the application during the last execution;

determining, for each of a predetermined number of frames of the plurality of frames, whether an address of a frame is within an address range of a code module of a plurality of code modules loaded by the application during the last execution, each of said code modules having an address range associated with a respective code module;

determining whether an origin attribute of the code module is third party; and

identifying a code module having the most frames within its address range and the origin attribute of third party as the cause of the crash of the application during its last execution.

16. The method of claim 14, where act of determining whether the origin attribute of the code module is from a third party comprises the acts of:

retrieving the descriptive attribute corresponding to an attribute type for the code module;

retrieving a descriptive attribute for each of the application and an operating system of an attribute type that corresponds to the attribute type for the descriptive attribute for the code module; and

determining whether the retrieved descriptive attribute of the code module does not match the retrieved descriptive attribute of the operating system and the retrieved descriptive attribute of the application.

17. The method of claim 13, further comprising the acts of:

presenting a user interface to the user identifying the third party supplemental code module as the cause of crashing the application during its last execution and querying the user as to a selection in response to the identification of the third party supplemental code module; and

receiving the user'"'"'s selection in response to the querying.
