摘要:
In a distributed system that includes a debug server and debug clients coupled for data communications through a data communications network, where the debug server includes a debug administrator, a message router, a back-end debugger, and a debuggee, collaborative software debugging includes receiving application-level messages, including a request from a requesting debug client to notify other debug clients of an expansion of a multi-member variable; routing the application-level messages among the debug clients, the debug administrator, and the back-end debugger, including providing distributed control of the back-end debugger to the debug clients and distributing, to the other debug clients, a notification of the expansion of the multi-member variable; and returning to the debug clients in response to the application-level messages routed to the back-end debugger, client-specific debug results.

In a distributed system that includes a debug server and debug clients coupled for data communications through a data communications network, where the debug server includes a debug administrator, a message router, a back-end debugger, and a debuggee, collaborative software debugging includes receiving, by the debug server from the debug clients asynchronously during a debug session of the debuggee, a plurality of application-level messages; routing, by the message router in accordance with an application-level message passing protocol, the application-level messages among the debug clients, the debug administrator, and the back-end debugger, including providing distributed control of the back-end debugger to the debug clients with application-level messages routed to the back-end debugger; and returning, by the debug server to the debug clients in response to the application-level messages routed to the back-end debugger, client-specific debug results.

A method, system and computer program product for performing thread-specific display of breakpoints are disclosed. The method includes, in response to determining that an event received from a user interface is a request to update a source code of a software module, updating a source display pane and determining whether a first breakpoint is capable of firing in a current thread. In response to determining that the first breakpoint is not capable of firing in the current thread, the first breakpoint is displayed in an altered display state to indicate that the first breakpoint cannot be hit in the current thread.

A method and a system for displaying an image based on texts in the image are provided. The method of the invention for displaying the image includes: a text extracting step, extracting text regions in the image to be displayed; a text occupancy amount calculating step, calculating occupancy amount of the text in said image; a comparing step, comparing the calculated occupancy amount with a predetermined threshold; a display step, displaying the image in real size of the image if said occupancy amount exceeds said predetermined threshold. It is achieved to display the image to the user in a manner of satisfying the viewing aim of the user, and unnecessary load of the computer system is avoided.

A computer program debugger is disclosed which stores previous programs which have been debugged and the debug parameters which were considered when debugging. When a new computer program is to be debugged, the new debugger is invoked and it automatically compares the executing program to be debugged with the previous programs. When one or more of the debug parameters are so similar that it can be said that the computer program undergoing debugging matches a previously stored computer program, a user is given options to display the matching programs, the modules, the functions, the lines, and the debug parameters and to exchange debug parameters between the programs which can be used to mod4 the either or any of the programs. The user is further given the option to store the current program undergoing debugging as a new program to be considered in matching the next program to be debugged.

A method and system are provided for permitting a user of a data processing system to display particular ones of multiple overlapping graphic objects. A subregion within a display is specified by the user. A set of overlapping graphic objects which are at least partially displayed within the subregion is then determined. The specified display order of only these graphic objects which are at least partially displayed with the specified subregion is temporarily altered, in response to a user input.

The invention relates to the selective protection of blocks of text or other portions of a shared data object in collaborative computer based system from simultaneous manipulation by two or more users. The collaborative computer based system includes a network connecting a plurality of terminals for communication. Each terminal includes an output display device and a user input device. The collaborative computer based system includes a shared data object simultaneously accessible by a plurality of users of the system. Responsive to a user obtaining access to the shared data object, the user is assigned a cursor available for display on the visual display devices of all current users. A user may attempt to protect portions of the shared data object with a lock region by selecting position coordinates for such a lock region. If the position coordinates do not include any portion of any previously established lock region, a lock region is established, blocking manipulation of the portion of the shared data object so covered against changes associated with cursors other than that of the establishing user. Exercise of appropriate commands release a prior lock region associated with the user.

Thermal-aware source code compilation including: receiving, by a compiler, an identification of a target computing system, the identification of the target computing system specifying temperature sensors that measure temperature of a memory module; compiling the source code into an executable application including inserting in the executable application computer program instructions for thermal-aware execution, the computer program instructions, when executed on the target computing system, carry out the steps of: retrieving temperature measurements of one or more of the target computing system's temperature sensors; determining, in real-time in dependence upon the temperature measurements, whether a memory module is overheated; if a memory module is overheated, entering a thermal-aware execution state including, for each memory allocation in the executable application, allocating memory on a different memory module than the overheated memory module; and upon the temperature sensors indicating the memory module is no longer overheated, exiting the thermal-aware execution state.

In an embodiment, an address watch is established on a memory address while the execution of a first thread of a program is halted. In response to a second thread modifying memory contents at the memory address, encountering the address watch and halting, a determination is made whether a first variable in the program that represents the memory address is displayed on a user interface for the first thread. If the first variable in the program that represents the memory address is displayed on the user interface for the first thread, the value of the first variable is read and displayed on the user interface of the first thread.
