1. Field OF the Invention
The present invention generally relates to software systems and, more particularly, to systems that perform software updates.
2. Background of the Invention
Oftentimes software that is released for use contains flaws, or bugs. Such flaws can result in software that ceases to properly function under certain circumstances. In many instances, software fixes for particular flaws are available in the form of software updates, even before some users experience problems caused by the flaws that are being corrected. One or more software updates are sometimes delivered to a user's machine in the form of a software patch. Not all software users regularly update their software, however. In consequence, such users experience a higher rate of software failures in comparison to users who keep their systems updated with the latest software patches.
Not all software updates are necessary for every system, though. For example, some software updates are applicable only to specific types of hardware. Thus, users who take time to download and install every available software update may be doing so unnecessarily. This can represent a significant amount of wasted time since such software updates often require the user to reboot the system on which the software update is being installed.
The present invention relates to a method and a system for repairing a flaw in software. The method can include automatically identifying a failure during execution of the software, and automatically freezing a state of the software execution at a point of the software failure. In response to the failure identification, a failure handling application can be automatically executed, without disrupting the frozen state of the software execution.
Incident data that correlates to the frozen state of the software can be automatically generated. For example, at least one state indicator available in the frozen state can be collected into an incident report, and the incident report can be sent to a flaw database. A software patch that is selected based on the incident data can be automatically received, for instance from the flaw database. The software can be automatically updated with the software patch. Execution of the software can be automatically reinitialized in response to the software update.
The software update system can include a software monitor that automatically identifies a failure during execution of software, and automatically freezes a state of the software execution at a point of the software failure. The system also can include a failure handling application that is executed in response to the software monitor identifying the failure. The failure handling application can be executed without disrupting the frozen state of the software execution.
The failure handling application can automatically generate incident data that correlates to the frozen state of the software, automatically receive a software patch that is selected based on the incident data, and automatically update the software with the software patch. The failure handling application also can automatically collect at least one state indicator available in the frozen state into an incident report to generate the incident data. The failure handling application can send the incident report to a flaw database. In addition, the failure handling application can receive the software patch from the flaw database. The failure handling application also can automatically reinitialize execution of the software in response to the software update.
Another embodiment of the present invention can include a machine readable storage being programmed to cause a machine to perform the various steps described herein.
Preferred embodiments of the present invention will be described below in more detail, with reference to the accompanying drawings, in which:
The present invention relates to a method and a system for automatically diagnosing and repairing software flaws when a device experiences a software failure. In particular, the system can automatically identify a software failure that occurs during execution of the software. In response, the system can freeze the state of the software execution at the point of the software failure, and execute a failure handling application. The failure handling application can communicate incident data correlating to the frozen state of the failed software to a flaw database, and receive a software patch for updating the failed software. Once the software patch has been implemented, execution of the software can be reinitialized.
Referring to
The station 105 can be, for example, a mobile telephone, a personal digital assistant (PDA), a computing device, an embedded device, or any other system or device that can communicate with the server 110 over the communications network 115 and that can execute software 120. The software 120 can be, for example, an operating system or an executable application.
The station 105 can include a software monitor 125 that monitors the software 120. The software monitor 125 can be implemented in firmware that is provided for the station 105, or in an operating system executing on the station 105. For example, the software monitor 125 can be implemented in a low level of the operating system and monitor other components of the operating system, as well as executable software applications.
The software monitor 125 can monitor the software 120 to identify if, and when, a failure occurs during execution of the software 120. In response to detecting such a failure, the software monitor 125 can freeze a state of the software execution at the point where the software failure occurred, and execute a failure handling application 130. The failure handling application 130 can be implemented in firmware, the operating system, or as a standalone application operating on the station 105.
If, after the software failure, the station 105 is sufficiently operable to execute the failure handling application 130, the failure handling application 130 can be executed without a reboot of the station 105, and without disrupting the frozen state of the software 120. If, however, the station 105 is not sufficiently operable after the software failure, the station 105 can reboot into a safe mode in which the software 120 is not executed, or in which the software 120 is executed with only certain functions active. For example, when a software failure occurs, the software monitor 125 can communicate with the failure handling application 130 to determine whether the failure handling application can adequately implement software updates in the current system state. If not, the software monitor 125 can initiate a reboot of the station into the safe mode.
In an arrangement in which the station 105 is a wireless communication device, but the software failure causes the wireless networking capabilities of the station 105 to be compromised, another device or system (not shown) may be connected to the station 105 to facilitate communication with the server 115. For instance, the station 105 may be connected to a personal computer that communicates with the server 105 via the communications network 115. In this arrangement, one or more portions the failure handling application 130 can be implemented by the device or system to which the station 105 is connected.
The failure handling application 130 can examine the frozen software 120 and automatically collect state information 135 representative of the state of the software 120 at the time the software 120 was frozen. For instance, the software 120 can be provided with indicators that represent the most recent state of the software 120, and that are accessible when the software 120 is frozen. In one arrangement, the indicators can be contained in a data table or text file maintained by the software 120. When a software failure occurs and the software 120 is frozen, the failure handling application 130 can access the data table or text file to retrieve the state information 135.
If the software 120 must be restarted in safe mode to perform the software update, the indicators representing the state of the software at the time of the failure can be preserved. For example, the data table or text file can be copied to a backup file when the software 120 is restarted, or the data logging can be turned off in the software 120 during safe mode operation to prevent the state information 135 representing the frozen state of the software 120 from being overwritten.
The failure handling application 130 can process the state information 135 and generate an incident report 140, which can include state indicators correlating to the frozen state of the software 120. The failure handling application 130 can send the incident report 140 to the server 110 via the communications network 115. In particular, the incident report 140 can be sent to a flaw database 145 executing on the server 110. In another arrangement, the flaw database 145 can execute on a system communicatively linked to the server 110.
The flaw database 145 can evaluate the state indicators contained in the incident report 140 and automatically select a software patch 150 for repairing the failed software 120. For instance, the state indicators can be compared to incident data associated with various software flaws identified in the flaw database 145 to identify one or more flaws affecting the software 120. The flaw database 145 then can select software updates that correct the flaws and send the software updates to the failure handling application 130 in the software patch 150. The failure handling application then can update the software 120 with the software patch 150, and the software 120 can be reinitialized.
Referring to
Referring to step 208, the failure handling application can automatically collect into an incident report one or more state indicators available while the software is in the frozen state. At step 210, the incident report can be automatically sent to the flaw database. Proceeding to step 212, the state indicators can be automatically compared to incident data correlating to known flaws identified in the flaw database. The results of the comparison can be used to automatically select one or more software updates that may be applicable for repairing the failed software. The selected software updates can be automatically sent from the flaw data base to the station in a software patch, as shown in step 214. For instance, the software updates can be sent to the failure handling application.
At step 216, the failure handling application can automatically update the failed software with the software updates. Continuing to step 218, execution of the failed software can be automatically reinitialized.
