Embodiment Construction

[0026] Below, the method and device for testing local method calls provided by the present invention will be described in detail with reference to the accompanying drawings.

[0027] First, refer to figure 2 An embodiment of the method according to the invention will be described. figure 2 A flowchart showing a method for performance testing a local method call according to an embodiment of the present invention.

[0028] Such as figure 2 As shown, in step 201, in response to the event associated with the local method call, a copy of the performance test template is generated from the general performance test template for performance testing the local method call.

[0029] In the Java virtual machine, after the calling method calls the native method, the address of the native method will be bound, and at this time, a native method call related event such as the above-mentioned native method binding event (NativeMethodBind) will be started.

[0030] It should be noted that, ...

Abstract

The invention provides a method and a device for performance testing for local method call. The method comprises the following steps: responding to the related events of the local method call, and using a universal performance testing template for performance testing for the local method call to generate a performance testing template copy; filling the information required for performance testing for the local method call in the corresponding position of the performance testing template copy; and changing code execution processes to execute the performance testing template copy. According to the invention, when a local method is called, the performance testing for the local method is realized by dynamically inserting the performance testing template copy into the execution route at the assembly level. Thus, compared with the prior art, the invention does not need to provide a related agent aiming at each local method, has high feasibility, and almost can not cause any difference to system performance.

Description

technical field [0001] The present invention relates to profiling technology, and more particularly to a method and device for profiling local method calls. Background technique [0002] The performance testing technology is such a technology, which obtains various performance parameters during the execution process by tracking the execution process of the application program, so as to locate the performance bottleneck of the program, so as to optimize the application program in a targeted manner. [0003] A local method is a method that can be directly run on a local hardware platform without being interpreted by a virtual machine (VM, Virtual Machine). Typically, native methods can be used for purposes such as direct manipulation of computer hardware, improved program execution performance, legacy code reuse, and more. As we all know, in applications such as Java applications, native method calls are very common, mainly because many functions need to be implemented by usi...
