Abstract

The invention discloses an application program playback method and system. The method comprises the following steps that S1, a target machine downloads an application program of a host machine; S2, instrumentation is conducted on the application program, and execution information of the application program is obtained and uploaded; S3, a breakpoint is set at an event occurrence point corresponding to the application program according to event information, wherein the event information is obtained by analyzing and processing the execution information through the host machine, and the event information is information triggering task switching; S4, the application program is restarted, when the breakpoint is met in the execution process, tasks of the application program are switched according to task switching information, and the application program is executed according to an original operating sequence, wherein the task switching information is obtained through analyzing and calculating carried out by the host machine according to the event information. According to the application program playback method and system, instrumentation probes are used for recording the execution information of the application program, time and space consumption is greatly reduced, and the application program playback method and system can be applied to all systems such as embedded real-time systems.

Description

technical field [0001] The present invention relates to the technical field of execution replay, and more particularly to an application replay method and system. Background technique [0002] With the improvement of users' requirements on the performance of software systems, concurrent technology has been widely used. However, while the use of concurrent technology improves software performance, it also brings great difficulties to the development of software developers, especially for embedded software systems, due to the uncertainty of concurrent program execution and the irreproducibility of errors, This makes the traditional sequential program debugging method no longer applicable. In the development process of concurrent programs, execution replay technology is usually used to realize error reproduction and program re-execution during software debugging, that is, by recording and tracking the execution of the target program, and then under the same input conditions, a...
