Perfetto: perfetto is a brand new next generation platform-level tracking tool introduced in Android 10, and provides a universal performance detection and tracking analysis tool set for platforms such as Android, linux. The core is to introduce a brand new user space to user space tracking protocol, which fills the captured data into a shared memory buffer area and can be used for acquiring built-in data sources (such as locators) in the platform.

HWC: namely, a hardware synthesizer (Hardware Composer) is a component of the Android system and is responsible for synthesizing each interface element (such as graphics, text, video and the like) drawn in the application program into a complete screen image, and then outputting the complete screen image to a display.
Buffer: the content of the buffer, i.e. frame buffer, corresponds to the interface display content on the screen.
In one embodiment, as shown in fig. 1, an application detection method is provided, where this embodiment is applied to a terminal to illustrate the application, and it is understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, as shown in fig. 1, the method includes the following steps:
Step 101, for each frame of recording data generated by the Perfetto tool during the test target application, extracting the first vertical synchronization signal and the second vertical synchronization signal of each frame from the recording data.
When the target application is tested, for example, the smoothness of the running of the target application is tested, the Perfecto tool can record the generation process of each frame in the running of the application, and corresponding record data is generated. And, the Perfecto tool can visually present the recorded data.
The display process of the android system can be briefly summarized as: the android application program (namely application) caches the measured, laid out and drawn surface data, renders the cached data to a display screen through a Sufaceflinger, and refreshes the data through a refreshing mechanism of an android system.
Fig. 2 is a schematic diagram of recording data of a certain frame generated by the Perfetto tool, and as can be seen from fig. 2, in the current android system, a generating process of one frame corresponds to two vertical synchronization signals, namely a first vertical synchronization signal and a second vertical synchronization signal, namely a VSync-app signal and a VSync-sf signal, in the embodiment of the present application. Therefore, the embodiment of the application can extract the two vertical synchronous signals from each frame and analyze the two vertical synchronous signals. The embodiment of the application can test one target application, and can also test a plurality of target applications at the same time.
For any one of the target frames, in the case where the first vertical synchronization signal and the second vertical synchronization signal of the target frame are normal signals:
step 102, determining a timeout thread in the threads of the target frame based on a magnitude relation between the duration of the threads in the target frame and the signal period of the first vertical synchronization signal or the signal period of the second vertical synchronization signal.
For frames that need to be analyzed among the respective frames, these frames may be regarded as target frames. It will be appreciated that for each frame, the first and second vertical synchronization signals have respective signal periods, typically the inverse of the FPS. For example, 60FPS corresponds to a period of 16.6ms and 90FPS corresponds to a period of 11.1ms. In addition, the generation process of the target frame may correspond to the execution process of a plurality of threads, for example, the execution process of a main thread, the execution process of a rendering composition thread, and the like. Of course, these threads take time to execute. Based on this, the embodiment of the present application may determine the timeout thread in the thread of the target frame based on the magnitude relation between the duration of the thread in the target frame and the signal period of the first vertical synchronization signal, or based on the magnitude relation between the duration of the thread in the target frame and the signal period of the second vertical synchronization signal, that is, by comparing the duration spent by the thread executing process with the duration of the vertical synchronization signal.
And step 103, analyzing the blocking reason of the target application based on the determined timeout thread.
After determining the timeout thread, the cause of the jam of the target application can be analyzed by analyzing the timeout thread, for example, analyzing the contents of the thread name, the thread execution duration and the like. For example, due to which thread in which frame is executing too long resulting in a stuck.
Since a large number of frames are generated when detecting an application, each frame corresponds to a large amount of data including application data and system data. In view of this, according to the application detection method provided by the embodiment of the application, the first vertical synchronization signal and the second vertical synchronization signal of each target frame are extracted from the frame record data, instead of manually extracting massive record data, so that valuable information for analyzing the katon cause does not need to be manually screened out, and the extraction efficiency of the valuable information is greatly improved; in addition, according to the embodiment of the application, the overtime thread in the thread of the target frame is determined based on the magnitude relation between the duration of the thread in the target frame and the signal period of the first vertical synchronous signal or the signal period of the second vertical synchronous signal, so that the cause of the stuck of the target application is analyzed based on the overtime thread instead of manually analyzing massive recorded data, and the analysis efficiency of the cause of the stuck is greatly improved. In summary, when detecting an application, the method of the embodiment of the application can improve the detection efficiency of the application.
In one embodiment, as shown in fig. 3, step S102 specifically includes:
in step 1021, it is determined whether the sum of the first duration and the second duration of the target frame is greater than the signal period of the first vertical synchronization signal.
In the embodiment of the application, the first duration is the duration of the main thread of the target frame, and the second duration is the duration of the rendering thread of the target frame. For any one target frame generation process, the method comprises a main thread and a rendering thread. The main thread refers to an Application (APP) main thread, and the main thread is used for starting to execute drawing of one frame; rendering threads refer to APP rendering threads that function to apply buffers, process rendering commands, and the like. In the process of generating a frame, under normal conditions, when the first vertical synchronization signal arrives, the system sequentially starts the main thread and the rendering thread under the control of the first vertical synchronization signal, and executes the main thread and the rendering thread before the first vertical synchronization signal ends. However, after the first vertical synchronization signal ends, the main thread and the rendering thread may not be executed, which may cause that the frame cannot be rendered within a predetermined time, and further cause that the screen is stuck.
If yes, determining the main thread and the rendering thread of the target frame as timeout threads in step 1022.
For the above reasons, the embodiment of the present application may determine the timeout thread by determining a magnitude relation between a sum of the first duration and the second duration of the target frame and the signal period of the first vertical synchronization signal.
Step 1023, determining whether the third duration of the target frame is greater than the signal period of the second vertical synchronization signal. In this embodiment of the present application, the third duration is a duration of a rendering composition thread of the target frame. For the generation process of any target frame, the method further comprises a drawing synthesis thread, namely a thread for synthesizing the partial picture rendered by the rendering thread into a finished picture by using a Sufaceflinger. In the process of generating a frame, under normal conditions, when the second vertical synchronization signal arrives, the system starts the drawing synthesis thread under the control of the second vertical synchronization signal, and the drawing synthesis thread is executed before the second vertical synchronization signal ends. However, when the second vertical synchronization signal is over, the rendering and compositing thread is not yet executed, and this frame cannot be composited within a predetermined time, and thus the screen is blocked.
And step 1024, if yes, determining the drawing synthesis thread of the target frame as a timeout thread.
For the above reasons, the embodiment of the present application may determine the timeout thread by determining the magnitude relation between the third duration of the target frame and the signal period of the second vertical synchronization signal.
According to the method and the device for detecting the overtime thread, through judging the size relation between the sum of the first time length and the second time length of the target frame and the signal period of the first vertical synchronizing signal and the size relation between the third time length of the target frame and the signal period of the second vertical synchronizing signal, the overtime thread is not required to be manually analyzed from massive recorded data, automatic determination of the overtime thread is achieved, and therefore detection efficiency of application is improved.
In an embodiment, the application detection method of the embodiment of the application may further include:
and displaying the starting time point, the ending time point and the duration of the overtime thread and the name of the target application corresponding to the overtime thread in the interface of the Perfetto tool.
This step may be located after step 103. After determining the overtime thread, the embodiment of the application can extract the information such as the starting time point, the ending time point, the thread duration, the name of the target application corresponding to the overtime thread and the like of the overtime thread, and display the information in the interface of the Perfetto tool, so that an application developer can more intuitively know the information of the overtime thread, and the application developer can conveniently determine the cause of application blocking as soon as possible.
In an embodiment, the application detection method of the embodiment of the application may further include:
for any one of the target frames, it is determined whether the first vertical synchronization signal and the second vertical synchronization signal of the target frame are abnormal signals.
This step may be located after step 101. As described above, the signal period of the vertical synchronization signal is normally fixed, such as 11.1ms or 16.6ms. Sometimes, however, the signal period of the vertical synchronization signal may fluctuate for some unexpected reasons. For example, the period of the vertical synchronization signal of the previous frame is 16.6ms, and the period of the vertical synchronization signal of the next frame is 11.1ms, which may also cause the application to get stuck. Based on this, the embodiment of the present application may determine whether the first vertical synchronization signal and the second vertical synchronization signal of the target frame are abnormal signals, and if they are normal signals, execute step 102; if the abnormal signal is the abnormal signal, marking the abnormal signal and the time point of the abnormal signal, and displaying the abnormal signal and the time point of the abnormal signal in the interface of the Perfetto tool. By the method, on one hand, the reason for causing the application jamming can be obtained from the vertical signal dimension analysis, the comprehensiveness of the application jamming reason analysis is improved, and on the other hand, the method is beneficial to research and development personnel to quickly position the application jamming problem point based on the display content and improves the application detection efficiency.
In one embodiment, the step of determining whether the first vertical synchronization signal and the second vertical synchronization signal of the target frame are abnormal signals includes:
and step A, comparing the first period and the second period of the target frame with the standard signal period respectively.
In this embodiment of the present application, the first period is a period of the first vertical synchronization signal, and the second period is a period of the second vertical synchronization signal. The standard signal period of the embodiment of the present application may be a preset signal period, for example, 11.1ms, or 16.6ms.
And B, if the first period is the same as the standard signal period, comparing the first period of the target frame with the third period and the fourth period respectively, and judging whether the first vertical synchronous signal of the target frame is an abnormal signal or not based on a comparison result.
In this embodiment of the present application, the third period is a period of the first vertical synchronization signal of a frame preceding the target frame, and the fourth period is a period of the first vertical synchronization signal of a frame following the target frame.
Illustratively, the target frame is b frame, the previous frame of the target frame is a frame, the next frame of the target frame is c frame, and the third period refers to the period of the first vertical synchronization signal of the a frame, and is denoted as period a; the fourth period refers to the period of the first vertical synchronization signal of the c frame, denoted as period c. The period of the first vertical synchronization signal of the target frame is denoted as period b. If the period b is 11.1ms and is the same as the standard signal period, comparing the period b with the period a and the period c respectively, and judging whether the first vertical synchronous signal of the b frame is an abnormal signal or not based on the comparison result.
And C, if the second period is the same as the standard signal period, comparing the second period of the target frame with the fifth period and the sixth period respectively, and judging whether the second vertical synchronous signal of the target frame is an abnormal signal or not based on a comparison result.
In this embodiment of the present application, the fifth period is a period of the second vertical synchronization signal of a frame preceding the target frame, and the sixth period is a period of the second vertical synchronization signal of a frame following the target frame.
Still, a frame, b frame, c frame are described as examples. Illustratively, the fifth period refers to the period of the second vertical synchronization signal of the a frame, denoted as period a'; the sixth period is a period of the second vertical synchronization signal of the c frame, and is denoted as a period c'. The period of the second vertical synchronization signal of the target frame is denoted as period b'. If the period b 'is 11.1ms and is the same as the standard signal period, the period b' is compared with the period a 'and the period c' respectively, and whether the second vertical synchronization signal of the b frame is an abnormal signal is judged based on the comparison result.
According to the embodiment of the application, the abnormal vertical synchronous signal in the target frame can be determined, the reason for the application jamming is obtained through the vertical signal dimension analysis, and the comprehensiveness of the application jamming reason analysis is improved.
In one embodiment, the step B specifically includes:
if the first period of the target frame is different from the third period or the fourth period, the first vertical synchronization signal of the target frame is an abnormal signal.
Still, a frame, b frame, c frame are described as examples. Illustratively, if period b is different from period a, or period b is different from period c, indicating that a fluctuation occurs in the b frame, the first vertical synchronization signal of the b frame is an abnormal signal.
The step C specifically comprises the following steps:
if the second period of the target frame is different from the fifth period or the sixth period, the second vertical synchronization signal of the target frame is an abnormal signal.
Illustratively, if period b 'is different from period a', or period b 'is different from period c', also indicating that a fluctuation occurs in the b frame, the second vertical synchronization signal of the b frame is an abnormal signal.
According to the embodiment of the application, the abnormal vertical synchronous signals in the target frame can be determined based on the comparison between the target frame and the front frame and the rear frame of the target frame, and the reasons for causing application jamming are obtained through the vertical signal dimension analysis, so that the comprehensiveness of analysis of the application jamming reasons is improved.
In one embodiment, step 103 specifically includes:
analyzing the type of the katon reason according to the name, the starting time point, the ending time point and the duration of the timeout thread, wherein the type at least comprises: operating system platform performance type, application itself type, and memory resource occupancy type.
The cause of the application to get stuck may be caused by the performance of the android system, may be caused by the application itself, or may be caused by the performance of the memory. After determining information such as the name, the starting time point, the ending time point, the duration and the like of the timeout thread, the embodiment of the application can analyze the cause of the blocking based on the information. Referring to fig. 4, if the name of the timeout thread is the main thread, for example, the cause of the click can be classified as the application itself in fig. 4; if the timeout thread is named a rendering thread, the cause of the stuck may be categorized as the operating system platform performance of FIG. 4.
According to the embodiment of the application, the type of the jamming reason can be effectively analyzed, automatic determination of the type of the jamming reason is achieved, and therefore detection efficiency of application is improved.
In an embodiment, the application detection method of the embodiment of the application further includes:
extracting a target buffer for a target application from a plurality of buffers (buffers) for displaying screen contents;
the target buffer is shown along with an exception signal in the interface of the Perfetto tool.
Sometimes, the cause of the application to get stuck may be related to the buffers, e.g. the number of buffers is insufficient.
