The invention describes an automated software support system comprising automated bug filing and test case creation component to checkpoint a client process initial state and record the client process initial state changes while the client process undergoes sequence of states which need to be analyzed, such as software bug, deliver the recordings to a development node, where the problem can be debugged without reproducing the client process environment by using the recorded state to recreate initial state of the client program and by using the recorded log to simulate the client program execution forwards and backwards.

Multiple versions of a runtime system, such as a software emulation application that emulates a legacy hardware architecture, are allowed to co-exist in the memory of a new hardware architecture. The operating system software of the new hardware architecture reads configuration data from a database or table to decide which version of the runtime system is desirable for an application program or game that is being loaded or is currently running, and, if a match is found, only that runtime system is invoked. To reduce storage footprint, the different versions of the runtime system may be stored using “differential patching” techniques. In this configuration, the operating system will always launch the same basic runtime system binary, but it will select a different differential patch to apply at run-time based on the title as determined during the database lookup. In this fashion, future changes to the runtime system to correct software bugs, incompatibility issues, and the like only need to be tested for the relevant target application programs or games.

Scoring is used to prioritize the bugs and the scoring is extensible and adjustable allowing easy addition of new parameters and allowing the system to be modified for different bug types, software, or customers.

A system and method for improved software servicing by installation of an updated version is provided. Using branch versioning techniques that support multi-branch development and release versioning techniques that support multi-version development, an update package may include updated files for each branch or release version.

Additionally, any fix installed on a target machine running a particular version may be migrated when updating the target machine to a new version without losing the fix and regressing the change. Such an update may be uninstalled by reverse migration of any fixes before uninstalling files from the version update.

A method and apparatus for providing feedback to a programmer of a web based application notifying the programmer of application errors encountered by an end user of the application. A user error table is created to log application errors when a user computer is running the web based application. The present invention searches the user error table to determine whether an application error has occurred and only those errors which occur for a first time are forwarded to a server responsible for collecting the programmer's e-mail. A server error table is created to log those error messages received by the server and only those error messages which are unique are forwarded to the programmer. The programmer does not receive duplicate error messages relating to the same error and can use the feedback provided by the present invention to correct the application in subsequent versions. Error messages are filtered at the user computer level and at the server level such that the programmer will receive error messages for a particular programming error only once. The programmer is not inundated with multiple error messages relating to the same error by multiple users. Most preferably, the present invention is a computer program product incorporating known source code containing the means for providing feedback to the programmer of application errors stored on a server accessible to users who can download the application onto their user computers.

In one embodiment, a method for automatically identifying a program error in a computer program includes receiving a program error message indicating that a new program error has occurred during execution of the program and generating a program stack trace for the new program error indicating the source of the new program error within the program. A first operation is applied to a portion of the program stack trace to generate a first numerical code associated with the new program error. The first numerical code associated with the new program error is compared to one or more stored first numerical codes associated with previously identified program errors to determine whether the new program error is the same as a previously identified program error. If so, stored information associated with resolving the previously identified program error is provided for use in resolving the new program error.

A probabilistic machine learning model is generated to identify potential bugs in a source code file. Source code files with and without bugs are analyzed to find features indicative of a pattern of the context of a software bug, wherein the context is based on a syntactic structure of the source code. The features may be extracted from a line of source code, a method, a class and / or any combination thereof. The features are then converted into a binary representation of feature vectors that train a machine learning model to predict the likelihood of a software bug in a source code file.
