Abstract: A method includes performing an integration test on executable software units. The integration test fails and identifies a symptomatic executable software unit at which the failure of the integration test is detected. One or more modified source code files, including instructions likely responsible for the failure of the integration test, are located from a plurality of modified source code files. The location involves searching a binary change database for change history records relating to both the plurality of modified source code files and the executable software units. Degrees of functional interaction between portions of modified source code files corresponding to the change history records and portions of a source code file corresponding to the symptomatic executable software unit are determined. Based on this determination, the modified source code file(s) including the instructions likely responsible for the failure of the integration test are identified.

Abstract: Method and apparatus for accessing a block data storage device through a computer network to carry out remote diagnostic operations. The data storage device includes a data storage medium, a host interface port, a serial communication (COM) port and a programmable controller with associated platform firmware and associated diagnostic firmware. A client computer and a server computer are connected to a computer network, and the data storage device is connected to the server computer via the host interface port. The server computer is used to transmit a first command to cause the controller to execute the platform firmware, while the client computer is used to transmit a second command to the COM port of the data storage device to cause the controller to concurrently execute the diagnostic firmware to monitor operation of the platform firmware.

Abstract: Method and apparatus for remote data acquisition from a block data storage device having a data storage medium, a host interface port, a serial communication (COM) port and a programmable controller with associated platform firmware and associated diagnostic firmware. A client computer and a server computer are connected to a computer network (such as the Internet), and the data storage device is connected to the server computer via the host interface port. A data acquisition device such as a disk drive analyzer having digital oscilloscope capabilities is connected to the server computer and the data storage device. Requests from the client computer are transmitted via the network to result in a first command to the data storage device to execute the platform firmware and a second command to capture a waveform signal from the data storage device. The waveform signal is transmitted real time for display by the client computer.
