A count of BBs executed by a program, which serves as a coarse-grained measure of how much code has run so far. Represented by an integer starting at
1and increasing as execution progresses.
A location at which the program will be stopped and control returned to the debugger.
- event log¶
A record of non-deterministic events in the execution history of a program.
- execution history¶
A record of the behaviour of a program in a form that can be replayed by the Plugin.
The Java Debug Wire Protocol (JDWP) is used for communication between a debugger such as IntelliJ and (usually) the agent inside a Java Virtual Machine. The Bridge has its own implementation of this protocol.
The Keyserver is Undo’s license server. This component needs to be installed if the Plugin is to be used with a floating license. The Plugin needs to have network access to the machine running the Keyserver.
An Undo product that provides API calls to start recording an application and to save a recording that can be loaded later.
- LiveRecorder recording¶
- program counter¶
A register whose value is the address of an instruction to be executed. When the program is stopped in the debugger, its value is typically the address of the next instruction to be executed.
- record mode¶
In this mode the program’s execution history is being recorded so that it can be saved or replayed. As long as execution proceeds forwards, the program remains in record mode, but reverse-execution actions and time-travel actions need to switch to replay mode.
- replay mode¶
- reverse-execution actions¶
- time-travel actions¶
LiveRecorder recognises timestamps in the following default formats:
MMM dd, yyyy hh:mm:ss a. You can add other time formats under Settings › Tools › LiveRecorder › Timestamp patterns.
- Undo Engine¶
The technology implementing record, replay, and time travel debugging.
A former name for LiveRecorder.
- wall-clock time¶
A description of a calendar date and clock time. Compare with time.
A watchpoint is a type of breakpoint that stops the program when the value of an expression changes.
