## Background
FIELD OF THE INVENTION
The present invention relates generally to software debugging environments, and more specifically to systems and methods for generating executable, interactive objects from data captured in response to a program code failure.
BACKGROUND
Modern software programs can be complex and consist of many components that interact with each other. When problems arise such as a program failure during execution, a software developer or a quality assurance engineer, support technician, or other troubleshooter will attempt to isolate the problem in an effort to correct the error or otherwise debug the suspect component, for example, by providing a code fix or other resolution. Typically, a software program at fault is running on a remote location not accessible by the software vendor. In order to determine the cause of the software failure, the developer or support engineer will attempt to reproduce the environment in which the problem occurred. The advantage of reproducing the problem in house is that the developer or support engineer can attach a debugging tool, referred to as a debugger, to observe the state of the objects around the failure point. This can be useful for providing information as to what the problem is and how to fix it. However, reproducing a problem at a software application or software solution level may be difficult due to complex component dependencies, software configuration, data used, and custom end user code involved. Thus, instead of trying to reproduce the entire end user's software setup, for example, in house by the software vendor's support team, a portion of the end user's software runtime environment around the failure point can be reproduced. With this localized environment around the suspect object class or component, a debugger can be attached to this environment to see the contextual state of the objects about which the suspect component is interacting in order to obviate the need for debugging in a larger product environment.

DETAILED DESCRIPTION
In the following description, specific details are set forth although it should be appreciated by one of ordinary skill that the systems and methods can be practiced without at least some of the details. In some instances, known features or processes are not described in detail so as not to obscure the present invention.
The contextual information corresponding to a localized environment can be captured in a log file, trace, memory dump, and the like, and can be used by software developers to determine a source of the software problem. However, the process of reading flat-file, text-based logs, traces, and the like can be tedious and time-consuming, as well as prone to human error. For example, a support engineer can step through the code to inspect the variables along the way containing the expected values, which is a manual process that requires tedious visual inspections.
Custom probe programs can be provided to ameliorate the manual requirements of a support engineer. Here, the probe program can be run when certain breakpoints are encountered. However, when interacting with program execution errors, the user must be attached to the live running process at the time the error occurs. This requires the support engineer to complete the cumbersome task of recreating the offending environment, for attaching the probe programs. As most errors are not expected and offending environments are not readily available, the ability to avoid recreating such environments and to recreate the offending code artifacts is important.
In brief overview, systems and methods are provided for transforming relevant log or trace data into an active in-memory representation of the objects which reflect a localized representation of the original environment in which a software component failed. During operation, contextual object information related to a program failure is automatically extracted from a log, trace, dump, and the like that is generated during execution of the program. The systems and methods can instantiate corresponding objects in memory from the contextual object information by deserializing, or inflating, the captured object data. Accordingly, the logged data can be converted into interactive in-memory objects, which when deserialized can be used locally by a sandbox or other debugging tool for reproducing the failure, identifying the source of the error, and the like. In this manner, a standalone runtime environment can be reproduced around just the failure section of the program code so that a debugging tool can be used to analyze the object states in that area captured at the time of failure.
Accordingly, the systems and methods automatically create an in-memory environment which, to an extent, represents the relevant section of the user's environment. A developer can therefore avoid the laborious effort of analyzing log or trace files, or the need of a debugger being attached to the full live running production process at the time the error occurs, for example, debugging code that is executed when breakpoints are encountered. Instead, the systems and methods of the present inventive concepts permit direct interaction with the deserialized in-memory objects, so that problem determination can occur when isolated to a simple unit-test sandbox or other debugging tool. This manner of creating an executable and interactive environment with respect to the objects in the files, as opposed to remaining a passive text-based repository as with flat log files, permits a developer to utilize the logged information to recreate the original conditions under which the exception or error was generated at will, without additional software or environmental concerns.
FIG. 1 is a block diagram of an interactive debugging environment 10 in which embodiments of the present inventive concepts can be practiced. The interactive debugging environment 10 includes a computer system 100 having program code therein that is experiencing a failure, for example, program code related to an application 104. The interactive debugging environment 10 also includes an error analyzer 116 and an optional test unit, for example, a debugging tool.
The computer system 100 includes a processor 101, a memory having a container 102, a data serializer 112, and/or a data repository 110, and a network interface 103, which can communicate with each other via a bus and/or data connector, for example, a Peripheral Component Interconnect (PCI) bus. The computer system 100 can include an application server or related server used in a development environment.
The network interface 103 can include one or more adaptors for communicating with the error analyzer 116 and/or other electronic devices via a network 12 such as a WAN, LAN, Internet, public network, private network, and the like, or via a direct connection.
The memory can include volatile memory, for example, RAM and the like, and/or non-volatile memory, for example, ROM, flash memory, and the like. The memory can include removable and/or non-removable storage media implemented in accordance with methods and technologies known to those of ordinary skill in the art for storing data. Stored in the memory can include program code, such as program code of an operating system executed by the processor 101, and/or program code corresponding to contents of the container 102, for example, an application 104.
The container 102 includes at least one application 104, a logging layer 106, and an exception handler 108. The container 102 can include a web container, an Enterprise JavaBeans (EJB) container, a Service Component Architecture (SCA) container, or other runtime platform. for elements of the application 104 stored in the memory. The application 104 can include an object oriented application, for example, a Java® application, or other application including program code that can reside in the memory of the computing system 100.
The logging layer 106 can capture information related to an exception during program execution, for example, program code of a component of the application 104 experiencing a failure, and store the captured information in the data repository 110. The data repository 110 can be part of the computer system 100 as shown in FIG. 1, or can be located separately from the computer system 100 and in communication with the computer system 100 via the network 112, a direct connection, or other connection. The data repository 110 can receive and store logs, traces, dumps, and the like, which can be in the form of character or text files for processing by the error analyzer 116. The logging layer 106 can include different logging levels, for example, configured for performing logging at one or more different levels of granularity with respect to the captured information, thereby allowing for a variable amount of reconstruction depending on the debugging requirements. Multiple logging levels can allow for referenced in-memory classes to be serialized as well as for white-box debugging. Alternately, they can be omitted for black-box debugging for performance-related reasons.
The exception handler 108 can catch and handle exceptions by executing a snapshot of active classes around where a program component failure occurs. The snapshot can be correlated with exception data stored as log files and the like in the data repository 110. The snapshot can include the current values of member fields of one or more classes, current values of input parameters, local variables, and the like of the method that created the object, and/or other attribute data related to a class corresponding to a given object. The snapshot permits a copy of all the local variables to be bundled as a file along with the objects for future reference.
The data serializer 112 can serialize the data into a file and output the file to the data repository 110 or other storage device. The data serializer 112 can be part of the computer system 100, or can be part of a different computer system having a processor, memory, network interface, etc. The data serializer 112 serializes the data snapshot generated by the exception handler 108 into an exception bundle. The exception bundle can be generated in a text format, for example, a flat file text-based log. The exception bundle can be stored in the data repository 110 or other database known to those of ordinary skill in the art, and/or transmitted to the error analyzer 116. A developer or other user can recreate the in-memory reference objects to a state at the time of the anomalous event, for example, an exception. The captured exception data can be stored in a flat-file or xml based layout, and the like. Portions of the captured runtime information can include binary or compiled code objects, and the like.
The error analyzer 116 includes a processor 117, a memory 119 having an in-memory interactive object generator 118, and a network interface 119, which can communicate with each other over one or more communications busses, for example, a Peripheral Component Interconnect (PCI) bus. The in-memory interactive object generator 118 converts the serialized data received from the data serializer 112 into an active in-memory representation of those objects that reflect a localized representation of the original environment in which a software component failed. In particular, the in-memory interactive object generator 118 can repopulate the snapshot taken by the exception handler 108 with reconstructed in-memory values and the like by instantiating objects corresponding to the contextual object information extracted from the captured log, trace, or dump data, which can be restored to a state at the time of the exception. The in-memory interactive object generator 118 can output the object classes as well as a generated driver class for testing the deserialized results to the test unit 120, for example, a JUnit sandbox or other debugging tool. The test unit 120 can process the in-memory reference objects, restored to a state at the time of the exception, without the need for the test unit 120 to be attached to a running debugging process.
FIG. 2 is a block diagram of the in-memory interactive object generator 118 shown in FIG. 1, in accordance with an embodiment. The in-memory interactive object generator 118 can execute entirely on the error analyzer 116, or a different standalone computer platform. Alternatively, some elements of the in-memory interactive object generator 118 can execute on the error analyzer 116 or other computer platform, while other elements execute on a remote computer such as the test unit 120 or the computer system 100. The in-memory interactive object generator 118 can include hardware, software, firmware, or a combination thereof. The in-memory interactive object generator 118 includes an object extraction module 206 and an object inflation module 208.
The object extraction module 206 receives error logs with serialized object data as input, and automatically extracts contextual object data from the error logs. The contextual object data can be extracted from sections of an error log corresponding to an area of program code proximal to a failing software component or components. The error logs can include application log and trace files, operating system log files, memory dumps, and the like, and be provided by a logger 106 and/or event handler 108.
The object inflation module 208 converts the serialized contextual object information of the received error logs into an executable and interactive environment. This can be achieved by the object inflation module 208 generating an in-memory representation of the objects, which can provide a localized representation of the original environment around the failing component, for example, a state of the objects at the time of the thrown exception The deserialized object inflation module 208 can reconstruct memory values and the like from the extracted contextual object information. The reconstructed in-memory values of the captured objects can be used, for example, by a developer or support engineer when stepping through a malfunctioning portion of the software program line-by-line. Since active in-memory interactive objects are generated, these objects can be used locally, for example, in a sandbox environment, or any debugging environment that enables a support engineer, a developer, etc. to see the in-memory representation of the objects around where an anomalous condition such as an error, exception, and the like, and to quickly debug the program code to identify the source of the component failure.
FIG. 3 is a flowchart illustrating a method 300 for generating interactive objects from passive log data, in accordance with an embodiment. In describing the method 300, reference is also made to FIGS. 1 and 2. The method 300 can be governed by instructions that are stored in a memory and executed by a processor of the computer system 100 and/or the error analyzer 116.
At block 302, an anomalous condition such as an exception or related event or error is detected. The anomalous condition can include a throwable exception or error. The anomalous condition can be detected according to tools and/or techniques known to those of ordinary skill in the art.
At block 304, object data can be captured. In an embodiment, the object data includes contextual object information extracted from passive log, trace, or memory dump files proximal to an area of code where the exception occurred, for example, near an area of a failed program component. In an embodiment, a snapshot is taken of one or more active classes determined at the time of the exception occurrence, and stored, for example, in the data repository 110. The snapshot can include a snapshot of objects that are active at a specific point in time during execution. The snapshot can include the current values of member fields of one or more classes, current values of input parameters, local variables, and the like.
At block 306, an in-memory representation of objects related to the captured data can be generated. The objects can be instantiated in memory from the extracted contextual object data. The active in-memory representation of the objects can be created to reflect a localized representation of the original environment in which a software component failed. This can be achieved by the in-memory interactive object generator 118 repopulating the snapshot of the active classes with reconstructed in-memory values and the like related to the captured objects. The contextual object information of the captured log, trace, or dump data can be recreated as in-memory objects, for example, recreated to a state at the time of the exception.
At block 308, the in-memory representation of the objects can be used to reproduce component failure resulting in the anomalous condition. In an embodiment, the recreated objects are used locally to reproduce a failure, error, exception, and the like, for example, a Junit test environment. In another embodiment, the recreated objects are output to a debug tool, for example, for black-box or white-box debugging. In another embodiment, the recreated objects are used by the error analyzer 116 to allow a user, for example, a support engineer, to see the in-memory representation of the objects about where the error or exception occurred in the error
FIG. 4 is a flowchart illustrating a method 400 for debugging a software program, in accordance with an embodiment. In describing the method 400, reference is also made to FIGS. 1 and 2. The method 400 can be governed by instructions that are stored in a memory and executed by a processor of the computer system 100 and/or the error analyzer 116.
At block 402, a snapshot can be taken of an active class in response to an anomalous condition, for example, an exception thrown during the execution of a program. The snapshot can include current values of class member fields, method input parameters, local member fields, or other object-related data used to recreate a localized environment around the failing component.
At block 404, data captured from the snapshot can be serialized into an exception bundle. The exception bundle can be generated as a flat file or related format suitable for storing in a data repository and/or transmitting to a destination computer, for example, to a support engineer for debugging the program code under test.
At block 406, the snapshot data can be deserialized, for example, when the serialized snapshot data is received by the in-memory interactive object generator 118.
At block 408, the in-memory reference objects can be recreated, for example, to a state at the time of the exception. Accordingly, the original error condition can be reproduced in a localized environment from the in-memory reference objects.
FIG. 5 is a schematic block diagram illustrating a method 500 for converting logged data into an executable, interactive environment, in accordance with an embodiment. In describing the method 400, reference is also made to FIGS. 1 and 2.
A well-known Java program 502 entitled “Helloworld.java” is provided which, when compiled and run, prints the text string “HelloWorld” on a computer display.
An exception 504 is generated when the program 502 crashes. In this illustration, the program 502 crashed on line 11 in the method called “badmethod” in the “Helloworld” class (line 15 of the file Account.java). This method was called from line 1 of the file “Helloworld.java,” from the main method.
An error log corresponding to the exception 504 is output to the object inflation module 208. Object data of the program 504 is serialized for storing and is also output to the object inflation module 208. The object inflation module 208 can deserialize the helloworld class, and output a generated driver class 512, for example, to a test tool described herein. In addition, the object inflation module 208 can deserialize, i.e., inflate, the serialized object data of the classes, thereby converting the serialized object data into one or more in-memory objects. In this manner, the serialized object data can be restored to a state at the time of the exception. A software developer can therefore avoid analyzing the error log corresponding to the exception 504 and provide the output directly to a debugger.
