Abstract: A system and methods are provided for distributed tracing in a distributed application. In one embodiment, a method includes observing a plurality of messages sent and received among components of the distributed application, generating a probabilistic model of a call flow from observed messages of the distributed system, and constructing a call flow graph based on the probabilistic model for the distributed application. Distributed tracing may include observing messages by performing the subscription-based observation techniques and operations to receive, message traces describing messages being communicated among components of the distributed application. In this regard, the tracing service may merge message traces from different instrumentation points with message traces obtained by observing message queues to generate a probabilistic model and call flow graph.

Abstract: A computer program product and method for dynamically creating test scripts for software testing. The method includes selecting one or more reference scripts to create a selected script set, selecting one or more parameters to create a selected parameter set, generating permutations of the selected script set based upon the selected script set and the selected parameter set, and generating permutation test scripts for each of the generated permutations which include test code, a dynamic variable, and varying values for the dynamic variable amongst the permutation test scripts. Depending upon the scope of the parameters, the generation of permutations uses variations of an n-ary Cartesian product to determine the permutations and varying content of the generated permutation test scripts.

Abstract: One embodiment of the present invention provides a system for facilitating replacement of a system call in an application with a customized function call. During operation, the system re-links the application's executable file with additional code or dynamically injects the additional code to the application's executable file during run time. The additional code can change a pointer in a table which indicates addresses of imported functions so that the pointer indicates an address of the customized function call.

Abstract: A method is provided for providing consistent logical code across specific programming languages. The method incorporates preprocessor macros in a source computer program code to generate a program control flow. The preprocessor macros can be used to describe program control flow in the source programming language for execution in the source computer program code. The preprocessor macros can also be used to generate control flow objects representing the control flow, which converts the source computer program code into a general language representation. The general language representation when executed is used to output computer programming code in specific programming languages representing the same logical code as that of the source computer program code.

Abstract: A single software project in an integrated development environment (IDE) may be built for multiple target environments in a single build episode. Multiple different output artifacts may be generated by the build process for each of the target environments. The output artifacts are then deployed to the target environments, which may be homogeneous or heterogeneous environments. The same source project may be used to generate multiple output artifacts for the same target environment.

Abstract: The present invention extends to methods, systems, and computer program products for intelligently recommending schemas based on user input that defines a portion of a data structure. An intelligent auto-complete function can identify characteristics of the user input and, based on these characteristics, recommend schemas that are most likely to be selected by the user to complete the data structure or portion of the data structure. The identified characteristics of the user input can be compared to characteristics of defined schemas or of other data structures to identify schemas that are most likely to match the user's intent. These schemas are then recommended to the user. Such schemas can define the recommended shape of the data structure being defined, including data types for a particular column, columns to add to the data structure, or can define additional data structures to be added such as additional tables to a database.

Abstract: Systems and methods for just-in-time (JIT) code compilation by a computer system. An example method may comprise identifying a defined pattern in a byte stream, evaluating a conditional expression associated with the pattern, and compiling the byte stream into a native code, while excluding, in view of the evaluating, a portion of byte stream associated with the pattern.

Abstract: A method for forming an extension to a scripting language compiler is disclosed. A compiler of a machine receives a source code that has a new keyword to a scripting language of the compiler. An extension compiler module processes the source code to support the new keyword. The compiler and the extension compiler module generate an executable machine code based on a process of the extension compiler module and the compiler.

One embodiment of a method for implementing partial fault tolerance in a stream processing application comprising a plurality of stream operators includes: defining a quality score function that expresses how well the application is performing quantitatively, injecting a fault into at least one of the plurality of operators, assessing an impact of the fault on the quality score function, and selecting at least one partial fault-tolerant technique for implementation in the application based on the quantitative metric-driven assessment.

Abstract: A method, computer-readable storage medium, and computer system are provided. In an embodiment, in response to a command that requests setting a breakpoint at a line in a module, a determination is made whether a snapshot instruction exists before a machine instruction that implements a source statement at the line. If the snapshot instruction exists before the machine instruction that implements the source statement at the line, the breakpoint is set at the machine instruction that implements the source statement at the line. If the snapshot instruction does not exist before the machine instruction that implements the source statement at the line, the module is recompiled to add the snapshot instruction before the machine instruction that implements the source statement.

Abstract: An information processing system, computer readable storage medium, and method for documenting the execution of long running applications. A processor of the information processing system operates to continuously collect snapshots monitored from an executing application on a runtime system. The processor selects, based at least on user specified policies, collected snapshots that indicate a significant change in runtime behavior of the executing application on the runtime system. The processor annotates each of the selected snapshots with description of the significant change in runtime behavior of the executing application. The processor operates to store and update documentation of an execution history of the executing application from the annotated snapshots.

Abstract: An apparatus and method for aiding in debugging and optimizing software is presented, in particular for instrumenting software to trace function calls. Source code is compiled with placeholder memory ranges. While executing the compiled binary object, a call-trace profiling function is inserted into at least certain of the placeholder memory ranges to log call-trace profiling data. Then, the compiled binary object is restored to its original state by removing the call-trace profiling function(s). A NOP function can be inserted in each placeholder memory range during compilation.

Abstract: An aspect of the present invention generates test cases for functional testing of a software application. In one embodiment, rules specifying corresponding patterns in a natural language and corresponding templates are maintained. Each pattern contains corresponding variables and words of the natural language together in an ordered sequence. On receiving a design document containing statements in the natural language, a first statement is determined to match a first pattern specified in a first rule. A match is deemed to exist only if the words in the first pattern exist in the first statement in the same corresponding positions of the ordered sequence, and if the first statement also contains values for each of the variables specified in the first pattern. A set of test cases is generated based on a first template specified in the first rule and the values for each of the variables.
