SYSTEM AND METHOD FOR PROVIDING A WATCHDOG TIMER TO ENABLE COLLECTION OF CRASH DATA

摘要

A system and method for providing a watchdog timer to enable collection of crash data is provided. Upon execution of certain operations, a source thread of an application initiates a watchdog thread that periodically sample state of data relating to the application. Should the operation not complete within a watchdog timeout period, the watchdog thread invokes a crash function to collect additional state data. At least a portion of the state data is stored for later analysis and debugging.

1. A system comprising:
a memory storing an application and a crash data structure; a computer processor executing the application having a source thread and a watchdog thread,
wherein the source thread initiates a predefined operation having an operating system timeout period, andwherein the watchdog thread enables the computer processor to:
determine, prior to completion of the predefined operation and prior to expiration of the operating system timeout period, that a predefined watchdog timeout period is expired, wherein the watchdog timeout period is less than the operation system timeout period;invoke a crash function to collect state information relating to the application in response to determining that the predefined watchdog timeout period is expired; andstore the state information in a crash data structure.
