A method and information processing system facilitate debugging of a multi-threaded application. A control program request associated with at least one thread of a process that has been designated for debugging is generated. The control program request is placed into a memory buffer associated with the thread by the debugger. The memory buffer is passed to a control program. A plurality of memory buffers is monitored. Each memory buffer in the plurality of memory buffers is associated with a different thread of the process. At least one memory buffer in the plurality of memory buffers is determined to include debugging event information from the control program determining. The debugging event information is processed. The processing includes at least one of notifying a user of the debugging event information and generating at least one control program request for a thread associated with the at least one memory buffer.

Embodiments of the invention provide a method, system and computer program product for selectable data on file viewing in a debugger. A method includes specifying a file in a user interface of a debugger executing in memory of a computer and debugging a target application and determining whether to view data in the file from a perspective of the computer or the target application. The method additionally includes loading the data in the file directly from the computer externally to the target application in response to determining to view the data in the file from the perspective of the computer, but otherwise loading the data through operations performed by the debugger on behalf of the target application in response to determining to view the data in the file from the perspective of the target application. Finally, the method includes displaying the loaded data in a file viewer of the user interface of the debugger.

An information processing system records an execution of a program instruction. A determination is made that a thread has entered a program unit. Another determination is made that that the thread is associated with at least one attribute that matches a set of thread recording criteria. An instruction recording mechanism for the thread is dynamically activated in response to the at least one attribute of the thread matching the set of thread recording criteria.

Another determination is made that that the thread is associated with at least one attribute that matches a set of thread recording criteria. An instruction recording mechanism for the thread is dynamically activated in response to the at least one attribute of the thread matching the set of thread recording criteria.

A computer program product integrates a code coverage tool with a debugger. A debugging process is performed on a set of source code for an application program. A set of code coverage information associated with the set of source code is analyzed with respect to a set of debugging information. The set of code coverage information at least identifies a set of instructions that has been executed. A set of source code lines in the set of source code that correspond to the set of instructions that has been executed is identified based on the analyzing. A user is notified through a user interface that the set of instructions associated with the identified set of source code have been executed.

Methods, systems, and computer program products for implementing a real-time, user configurable, debugging framework for use in debugging applications. A method includes executing an application on a computer, the application comprising a plurality of instructions including a debug macro instruction. The debug macro instruction is associated with a set of parameters for describing one or both of system and application conditions. The method also includes specifying one or more trigger criteria, the trigger criteria comprising a set of dynamic values for the set of parameters. The method further performing, while the application is executing, executing the debug macro instruction, detecting whether the trigger criteria have been met by the application, the detecting in response to executing the debug macro instruction, and upon detecting that the trigger criteria have been met, initiating a debugging session in response to the detecting.

A method for enhancing debugger performance of hardware assisted breakpoints across multiple units includes deferring all active location breakpoints within the multiple modules, and subsequently activating each valid location breakpoint in a present one of the multiple modules being entered.

The use of aliases in the debugging of applications is facilitated. Aliases are used in debugging, even when the aliases are not known to the debug generation stage of the compiler. That is, aliases are used in debugging, even when debug information is not generated by the compiler for the aliases. In order to use the aliases in debugging, the aliases are resolved to their formal names, and then debug information corresponding to the formal names, and thus, the aliases, is obtained.
