Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. In addition, the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a schematic flowchart of an information obtaining method according to an embodiment of the present invention, where the method may be executed by an information obtaining apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in an intelligent terminal device. As shown in fig. 1, the method includes:
By way of example, the smart terminal device may include a smart phone, a tablet computer, a notebook computer, a smart appliance, and other devices capable of loading an operating system. The embodiment of the invention does not limit the type of the operating system loaded in the intelligent terminal device, and the operating system can be an Android (Android) operating system, a Windows (Windows) operating system, a Linux operating system and the like.
For example, the preset application may include any application installed in the smart terminal device, or may include a preset part of the application. The technical scheme provided by the embodiment of the invention can be realized by utilizing a Software Development Kit (SDK), an application program developer writes the SDK, and accesses the SDK in a preset application program, so that the related functions of the technical scheme provided by the embodiment of the invention are realized in the SDK.
For example, the preset stuck state may be a state in which an abnormal condition occurs in the interface display of the predefined application program, and generally, regarding the display effect, the display may be represented by a phenomenon that the user interface is switched to be stagnated, slow or jumped, the user interface cannot be matched with sound, the content in the user interface is smeared, and the like, and an index for evaluating the stuck state may be set according to an actual requirement, which is not specifically limited in the embodiment of the present invention. Optionally, the stuck state may be evaluated based on a frame rate of the application program, for example, a frame rate of the preset application program in the operation process is obtained, and when it is detected that the current frame rate is smaller than a preset frame rate threshold, it is determined that the preset application program is detected to enter the preset stuck state. The preset frame rate threshold may be freely set, and may be, for example, 30Hz, i.e., 30 frames per second. In addition, the stuck state can be judged according to the drawing time length of the picture, the drawing interval of two adjacent frames of pictures, other items and the like.
In the related art, when an application program is stuck, context information of a main thread of the application program can be acquired through an exposed interface, but the information is not enough for analyzing and solving the stuck problem. In addition, when an Application generates an unresponsive (ANR) event, a trace file, such as a trace. txt file in an Android system, is generated inside the operating system, and information related to a current process when ANR occurs, such as a stack of the current process and some state information of a current virtual machine, is recorded in the trace file, so as to form trace information. However, the application program in the intelligent terminal device, especially the third-party application program, does not have the read-write permission of the file, and therefore, the relevant information in the trace file cannot be acquired for analyzing and positioning the stuck problem.
In the embodiment of the invention, when the preset application program is blocked, the limitation of the system to the application program can be broken through, and a trace information collection scene when the ANR occurs can be simulated, so that the blocking context information can be more comprehensively obtained, and the method and the device can be used for helping the preset application program to specifically solve the blocking problem. When the preset application program is detected to enter the preset stuck state, a pointer of a first system function of a Runtime (Runtime) object is acquired so as to call the first system function subsequently. The first system function includes a function for backing up (dump) runtime information when an application unresponsive event occurs, and in the Android system, the first system function is a dumpfigquit function. For convenience of explanation, the Android system will be described as an example.
Illustratively, Native (Native) methods may be written in advance, a Java Native Interface (JNI) layer call may be performed by calling the Native methods, and then a pointer of the first system function may be obtained. Specifically, a first dynamic link library may be opened, and a pointer of a runtime object in the first dynamic link library and a pointer of a first system function of the runtime object may be obtained. The first dynamic link library may be, for example, libart. And acquiring a pointer of a Runtime object unique to the system through a dlsym function, wherein the dlsym function can acquire the pointer of the Runtime object by accessing a symbol (symbol) table. After acquiring the pointer of the Runtime object, the pointer of the dumpfsigquit function of the Runtime object may be acquired continuously through the dlsym function.
And 102, calling the first system function through the runtime object, and transmitting an output stream into the first system function.
For example, through the call to the first system function, the system when the ANR event occurs in the application may be simulated to obtain the related information of the current process, that is, trace information, by calling the first system function. The output stream can be viewed as an output channel, and the output stream can be a byte output stream or a character output stream, such as OutputStream, Writer, or OutputStream Writer. By transferring the output stream into the first system function, the trace information obtained by calling the first system function can be written into the output stream.
And 103, acquiring information contained in the output stream to obtain the stuck context information.
Illustratively, the morton context information may include relevant information for analyzing morton, such as Java layer stack information, kernel (kernel) stack information, Native (Native) stack information, and other relevant information. Stack call information may be included in the stack information, such as attribute information (e.g., number) of the stack called, location of the call, and time of the call, among others. The stuck context information is included in trace information obtained by calling the first system function, and the stuck context information can be obtained by obtaining the information included in the output stream.
According to the information acquisition method provided by the embodiment of the invention, when the preset application program is detected to enter the preset stuck state, the pointer of the first system function of the runtime object is acquired, wherein the first system function comprises a function for backing up runtime information when the application program does not respond, the first system function is called through the runtime object, the output stream is transmitted into the first system function, and the information contained in the output stream is acquired so as to obtain the stuck context information. By adopting the technical scheme, when the application program is detected to be blocked, the blocking context information is obtained by calling the function called by the system when the application program has no response event, so that the system limitation can be broken through to obtain more comprehensive blocking context information, and the blocking problem can be accurately positioned and solved.
On the basis of the above embodiment, the stuck degree corresponding to the preset stuck state may be lower than the stuck degree corresponding to the application no-response event. The method has the advantages that due to the fact that the stuck degree is relatively serious when the application program has no response event, and when the stuck degree is not serious, the technical scheme provided by the embodiment of the invention can be used for obtaining stuck context information, the process of obtaining trace information when the ANR event occurs is simulated in advance, the stuck context information is further obtained, targeted analysis can be carried out on stuck problems with different degrees, and the stuck problem of the application program is solved more comprehensively.
On the basis of the above embodiment, after obtaining the morton context information, the method further includes: and writing the pause context information into a preset local file, and/or reporting the context information. The method has the advantages that the acquired katton context information can be stored or reported in time, and developers can analyze the katton problem conveniently. For example, the preset local file may be a newly created local file or an existing local file, which is not limited in the embodiment of the present invention. After the card pause context information is obtained, the card pause context information can be written into a preset local file, a preset application program has the permission of reading the preset local file, and the preset local file can be read when the card pause context information needs to be used, for example, a background server corresponding to the preset application program can read the preset local file through the preset application program, and then the card pause context information when the preset application program is in a card pause state is obtained. After the katoon context information is acquired, the katoon context information can also be directly reported, for example, to a background server corresponding to a preset application program, and a developer can analyze the katoon problem and solve the katoon problem according to the reported katoon context information in time. In addition, after the katoon context information is acquired, the katoon context information can be written into a preset local file firstly, and then the preset local file is reported, so that the purpose of reporting the katoon context information is achieved.
Example two
Fig. 2 is a schematic flow chart of an information obtaining method according to a second embodiment of the present invention, where optimization is performed based on the second embodiment, and related steps of creating a sub-process and obtaining morton context information by using the sub-process are added.
Illustratively, when detecting that the preset application program is stuck, obtaining a pointer of a first system function of the runtime object includes: when detecting that a preset application program is blocked, creating a child process of a first process of the preset application program, wherein the first process becomes a parent process, and acquiring a pointer of a first system function of an object in operation by using the child process. The calling the first system function through the runtime object and transmitting an output stream into the first system function includes: and calling the first system function through the runtime object by utilizing the subprocess, and transmitting an output stream into the first system function. The obtaining information contained in the output stream to obtain the stuck context information includes: acquiring information contained in the output stream by using the child process, and acquiring preset types of stack information of all threads of the parent process by using the child process; and obtaining the pause context information according to the information contained in the output stream and the stack information of the preset type. The method has the advantages that the created sub-process can be used for acquiring partial trace information of the main process of the preset application program, and the acquired other stack information is combined to obtain complete stuck context information, so that the multi-process scheme can effectively reduce or even avoid negative effects such as breakdown or secondary sticking on the preset application program.
Further, after obtaining the stuck context information according to the information contained in the output stream and the stack information of the preset type, the method may further include: and transferring the stuck context information to the parent process by utilizing a child process in a cross-process communication mode. The method has the advantages that the blocking context information is transmitted to the parent process, and the parent process can report the blocking context information conveniently in time. The cross-process communication mode may be, for example, an anonymous shared memory mode.
Optionally, as shown in fig. 2, the method may include:
The first process is a main process of a preset application program and is also a parent process of the created child process. Illustratively, the JNI layer may be called by calling a Native method written in advance, and then creating a sub-process of the current process of the preset application program by using a fork function.
And step 204, acquiring the information contained in the output stream by utilizing the subprocess.
The execution process of step 202 to step 204 is similar to that of the above embodiment, except that the sub-process is used for completion, and is not described herein again. In addition, since the child process is used to complete the process, when the child process calls the first system function, the output stream only includes part of the morton context information, and the preset type stack information of all threads of the parent process is not included, and needs to be acquired separately through the following steps.
And step 205, acquiring preset types of stack information of all threads of the parent process by using the child process.
Illustratively, the preset type of Stack information includes kernel Stack (kernel Stack) information and Native Stack (Native Stack) information, and the information included in the output stream acquired by the child process includes Java layer Stack (Java Stack) information of all threads of the parent process.
Optionally, the obtaining, by the child process, kernel stack information of all threads of the parent process includes: and acquiring pointers of the thread list objects of the objects in operation through the child process, traversing all threads of the parent process, and acquiring corresponding kernel stack information by reading preset stack file directories corresponding to all processes respectively. The pointer of the ThreadList object can be obtained through runtime- > GetThreadList (), the ForEach function pointer of the ThreadList object is obtained through dlsym, the ForEach function is called to traverse all threads (Thread) of the parent process, and the Kernal Stack of the Thread of the parent process is obtained through reading/proc/ppid/task/tid/Stack.
Optionally, the obtaining, by the child process, kernel stack information of all threads of the parent process includes: and opening a second dynamic link library, acquiring a pointer of a second system function, and acquiring local stack information of all threads of the parent process by calling the second system function, wherein the second system function comprises a Backtrace function. The method comprises the steps of opening a libbtacktrace dynamic link library through dlopen, then obtaining a backstrace function pointer through dlsym, and obtaining Native stacks of all threads of a father process by calling the function pointer to specify the father process and the threads.
And step 206, utilizing the subprocess to obtain the stuck context information according to the information contained in the output stream and the stack information of the preset type.
Illustratively, the acquired incomplete morton context information, the Kernal Stack and the Native Stack may be assembled or summarized by the sub-process to obtain complete morton context information.
And step 207, transmitting the stuck context information to the parent process by utilizing the child process in an anonymous memory sharing mode.
And step 208, writing the morton context information into a preset local file through the parent process and reporting the information.
According to the information acquisition method provided by the embodiment of the invention, when the preset application program is detected to enter the preset stuck state, the child process of the preset application program is firstly created, partial trace information of the main process of the preset application program is acquired by utilizing the child process, and the complete stuck context information is acquired by combining with the acquired other stack information of the parent process, and is transmitted to the parent process, and then the parent process writes the complete stuck context information into a local file and reports the complete stuck context information.
On the basis of the above embodiment, optionally, the version number of the android operating system is lower than a preset version number, and the preset version number can be freely set, for example, the version 8.0. At present, in the world, especially in the third world, there are still many people using low-cost low-end intelligent terminal devices with less advanced hardware facilities, because the complexity of the application program has higher and higher requirements for hardware resources, the probability of the application program being stuck or even having no response on the low-end model is higher, and the version of the operating system generally installed on the low-end model is lower, and based on the factors such as compatibility and performance, for the low-version operating system, the multi-process scheme can be adopted to collect the stuck information of the application program, thereby reducing or even avoiding the negative effects such as breakdown or secondary sticking on the preset application program. For a high-version operating system, the implementation can be realized by adopting the related technical scheme in the first embodiment, that is, the katon context information is directly obtained through the process of the preset application program, so that the information obtaining efficiency can be improved, and the katon problem can be conveniently and timely analyzed.
