ActiveUS20050131871A1Facilitate search queriesData processing applicationsDigital data processing detailsClient-sideProgram trace
An Internet-scale file sharing system includes a client-side file sharing application that allows file-sharing users to identify files to share and transmit metadata corresponding to those files to a metadata repository. A server-side application operating on the metadata repository tracks metadata received from associated file-sharing users, as well as metadata from other affiliated metadata repositories. Each metadata repository acts as a search engine for any querying users and can provide search results based on locally stored metadata alone. Each metadata repository may additionally choose to locally-store popular files from an associated file-sharing user so as to alleviate transmission burdens on that file-sharing user. Associated metadata repositories each periodically synchronize their stored metadata so that all metadata repositories may generate similar search results. In such manner, file-sharing queries need only be performed by the metadata repository receiving the query, and not by all associated metadata repositories.

Debugger apparatus and method for indicating time-correlated position of threads in a multi-threaded computer program
InactiveUS20070168968A1Error detection/correctionSpecific program execution arrangementsTimestampProgram trace
A debugger inserts instrumentation hooks in a multi-threaded computer program that allow collecting a program trace and that provide timestamps that correspond to the program trace. When a breakpoint in a first thread is encountered, a timestamp corresponding to the breakpoint is retrieved. Execution of the other threads may continue until the debugger is able to halt their execution. Once the execution of all threads has been halted, the program trace for each thread is traced backwards to a point where the timestamp is less than the breakpoint timestamp. Instructions are then executed, one by one, until the execution time of the instructions plus the timestamp is approximately the same as the breakpoint timestamp. The instruction in the program trace display is then highlighted to indicate the instruction that was likely being executed when the breakpoint in the first thread is encountered.

System and method for verifying computer program correctness and providing recoverable execution trace information
In a system for statically analyzing a specified computer, a verification condition generator converts the program into a logical equation, called a verification condition, and inserts program flow control labels into the sub-equations of the verification condition. The flow control labels identify conditional branch points in the specified computer program. A theorem prover is applied to the logical equation to determine truth of the logical equation, and when the truth of the logical equation cannot be proved, the theorem prover generates at least one counter-example identifying one of the conditions, one or more variable values inconsistent with that condition, and any of the flow control labels for conditional branch points of the program associated with the identified variable values. A post processing module converts each counter-example into an error message that includes a program trace when the counter-example identifies one or more of the flow control labels.

An application (e.g., a computer program) prints data by invoking a print function with a format argument and, optionally, at least one data argument. The format argument and any data arguments are saved in a deferred trace data buffer. The print function returns to the application then, sometime after the print function has returned, the deferred trace data buffer is processed and the format argument and / or any data arguments are printed. By saving the format argument and any data argument(s) to a memory buffer instead of parsing and formatting the arguments in real-time, program efficiency may be improved and the impact of the print function on a software test scenario may be reduced.

ActiveUS20050177836A1Memory adressing/allocation/relocationMultiprogramming arrangementsTerm memoryProgram trace
A method for providing memory management for objects is described. Specifically, techniques are described for providing common memory management code to objects that are instances of different classes and for releasing a memory management subtree that starts with a particular object in the memory management tree. A memory management template provides common pre-processor memory management code. A specialized version of the memory management template is used to create a specialized template subclass. When a memory management operator of an object that is an instance of the specialized template subclass is invoked the common memory management code in the specialized template is executed. Memory is associated with each object in a hierarchical tree. Data for the memory is maintained that reflects the hierarchical tree relationship between the objects. A subtree and the associated memory can be released without an application program tracking the relationships.

Hardware-assisted program trace collection with selectable call-signature capture
InactiveUS20140059523A1Hardware monitoringSpecific program execution arrangementsProgram instructionProcessor register
Hardware-assisted program tracing is facilitated by a processor that includes a root instruction address register, a program trace signature computation unit and a call signature register. When a program instruction having an address matching the root instruction address register is executed, a program trace signature is captured in the call signature register and capture of branch history is commenced. By accumulating different values of the call signature register, for example in response to an interrupt generated when the root instruction is executed, software that performs program tracing can obtain signatures of all of the multiple execution paths that lead to the root instruction, which is also specified by software in order to set different root instructions for program tracing. In an alternative implementation, a storage for multiple call signatures is provided in the processor and read at once by the software.
