Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings. Furthermore, embodiments of the invention and features of the embodiments may be combined with each other without conflict.
Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts steps as a sequential process, many of the steps may be implemented in parallel, concurrently, or with other steps. Furthermore, 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 figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example 1
Fig. 1 is a flow chart of an information acquisition method according to an embodiment of the present invention, where the method may be performed by an information acquisition device, where the device 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, smart terminal devices may include smart phones, tablet computers, notebook computers, and smart appliances, among others, that are capable of hosting an operating system. The type of the operating system loaded in the intelligent terminal equipment is not limited, and for example, the operating system can be an Android operating system, a window (Windows) operating system, a Linux operating system and the like.
The preset application program may include any one of application programs installed in the smart terminal device, or may include a preset partial application program, for example. The technical scheme provided by the embodiment of the invention can be realized by utilizing a software development kit (Software Development Kit, SDK), an application program developer writes the SDK, and the SDK is accessed into a preset application program, so that the related functions of the technical scheme of the embodiment of the invention are realized in the SDK.
The preset click state may be a state in which an abnormal condition occurs in the interface display of the preset application program, and generally, for a display effect, the display may be that the user interface is switched to be stagnant, slow or skip, the user interface cannot be matched with sound, a phenomenon that a smear occurs in the content of the user interface, and the like, and an index for evaluating the click state may be set according to actual requirements. Alternatively, the stuck state may be evaluated based on a frame rate of the application program, for example, a frame rate of a preset application program in a running process is obtained, and when the current frame rate is detected to be 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, for example, it may be 30Hz, i.e. 30 frames per second. In addition, the stuck state can be judged according to the drawing time of the picture, the drawing interval of two adjacent frames of pictures, other items and the like.
In the related art, when the application program is blocked, the context information of the main thread of the application program can be obtained through the exposed interface, but the information is not enough for analyzing and solving the blocking problem. In addition, when an unresponsive (Application Not Responding, ANR) event occurs in the application program, a trace file, such as a trace file in the Android system, is generated in the operating system, and relevant information of the current process when the ANR occurs, such as a stack of the current process and some state information of the current virtual machine, is recorded in the trace file to form trace information. However, the application program in the intelligent terminal device, especially the third party application program, has no read-write authority of the file, and therefore, the related information in the trace back file cannot be obtained for analyzing and locating the stuck problem.
According to the embodiment of the invention, when the preset application program is blocked, the limitation of the system on the application program is broken through, and the trace information collection scene when the ANR occurs is simulated, so that the blocking context information is obtained more comprehensively, and the method is used for helping the preset application program to solve the blocking problem in a targeted manner. When the preset application program is detected to enter a preset clamping state, a pointer of a first system function of a run-time (run) object is obtained so as to call the first system function later. 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 dumpforsigquery function. For convenience of explanation, an Android system will be described below as an example.
For example, a Native (Native) method may be pre-written, a call of a Java Native interface (Java Native Interface, JNI) layer may be made by calling the Native method, and then a pointer to 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, a libart. So dynamic link library, which may be opened by a dlopen function, and a handle is returned to the dlsym function, where the handle may include an address of the libart. So dynamic link library. The pointer to the system unique run time object is obtained by a dlsym function that can access a symbol (symbol) table to obtain the pointer to the run time object. After the pointer to the Runtime object is obtained, the pointer to the DumpForSigQuit function of the Runtime object may continue to be obtained by the dlsym function.
By way of example, by calling the first system function, the system when the application program generates the ANR event can be simulated to obtain the related information of the current process, namely trace information, by calling the first system function. The output stream may be regarded as an output channel, and the output stream may be a byte output stream or a character output stream, such as OutputStream, writer or OutputStreamWriter, etc. By introducing 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.
For example, the katon context information may include relevant information for analyzing katon, such as may include Java layer stack information, kernel (Kernel) stack information, 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 called stack, the location of the call, the time of the call, and so forth. The stuck context information may be obtained by obtaining information contained in the output stream, from the trace information obtained by calling the first system function.
According to the information acquisition method provided by the embodiment of the invention, when the preset application program is detected to enter the preset katon state, the pointer of the first system function of the running object is acquired, wherein the first system function comprises a function for backing up the running information when an unresponsive event of the application program occurs, the first system function is called through the running object, an output stream is transmitted into the first system function, and the information contained in the output stream is acquired so as to obtain katon context information. By adopting the technical scheme, when the application program is detected to be blocked, the blocking context information is acquired by calling the function called by the system when the application program does not respond to the event, so that the system limit can be broken through, the more comprehensive blocking context information can be acquired, and the accurate positioning and the blocking problem solving are facilitated.
Based on the foregoing embodiment, the degree of blocking corresponding to the preset blocking state may be lower than the degree of blocking corresponding to the occurrence of the application unresponsive event. The method and the device have the advantages that as the degree of the blocking is serious when the unresponsive event of the application program occurs, and the blocking context information can be obtained through the technical scheme provided by the embodiment of the invention when the degree of the blocking is not serious, the process of obtaining trace information when the ANR event occurs is simulated in advance, the blocking context information is further obtained, the blocking problems of different degrees can be analyzed in a targeted manner, and the blocking problems of the application program can be more comprehensively solved.
On the basis of the above embodiment, after obtaining the katon context information, the method further includes: writing the katon context information into a preset local file, and/or reporting the context information. The advantage of setting up like this is that can in time preserve or report the card context information that obtains, the developer of being convenient for carries out the analysis to the card problem. 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 katon context information is obtained, the katon context information can be written into a preset local file, a preset application program has the authority of reading the preset local file, the preset local file can be read when the katon context information is needed 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 further the katon context information when the preset application program is katon is obtained. After the katon context information is obtained, the katon context information can be directly reported, for example, the katon context information is reported to a background server corresponding to a preset application program, and a developer can timely analyze the katon problem according to the reported katon context information and solve the katon problem. In addition, after the katon context information is obtained, the katon context information can be written into a preset local file, and then the preset local file is reported, so that the purpose of reporting the katon 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, wherein optimization is performed on the basis of the above embodiment, and related steps of creating a sub-process and obtaining katon context information by using the sub-process are added.
Illustratively, when the preset application program is detected to be blocked, acquiring a pointer of a first system function of the runtime object, including: when the occurrence of a pause of a preset application program is detected, 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 running 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 comprises the following steps: 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 katon context information includes: acquiring information contained in the output stream by using the child process, and acquiring stack information of preset types of all threads of the parent process by using the child process; and obtaining the katon context information according to the information contained in the output stream and the stack information of the preset type. The multi-process scheme can effectively reduce or even avoid negative effects, such as crashing or secondary cartoon, on the preset application program.
Further, after the katon context information is obtained according to the information contained in the output stream and the preset type of stack information, the method may further include: and transmitting the cartoon context information to the parent process by utilizing a child process through a cross-process communication mode. The setting has the advantages that the cartoon context information is transmitted to the father process, and the father process can report the cartoon context information in time conveniently. 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. For example, the JNI layer may be invoked by calling a pre-written Native method, and then creating a sub-process of the current process of the preset application using a fork function.
The execution of steps 202 to 204 is similar to that of the above embodiment, except that the execution is performed by using a sub-process, and the description thereof is omitted. In addition, since the sub-process is used for completion, when the first system function is called by the sub-process, only part of the katon context information is contained in the output stream, and the stack information of the preset type of all threads of the parent process is not contained, and the stack information needs to be acquired separately through the following steps.
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 obtained by the child process includes Java layer Stack (Java Stack) information of all threads of the parent process.
Optionally, acquiring, by the child process, kernel stack information of all threads of the parent process, including: and acquiring pointers of thread list objects of the run-time objects through the child process, traversing all threads of the parent process, and acquiring corresponding kernel stack information through reading preset stack file directories respectively corresponding to all the processes. The pointer of the Thread list object can be obtained through rutime- > GetThreadList (), the ForEach function pointer of the Thread list object can be obtained through dlsym, the ForEach function is called to traverse all threads (Thread) of the parent process, and the Kernel Stack of the Thread of the parent process can be obtained through reading/proc/ppid/task/tid/Stack.
Optionally, acquiring, by the child process, kernel stack information of all threads of the parent process, including: and opening a second dynamic link library, acquiring a pointer of a second system function, and acquiring the 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 library can be opened by dlopen, then a Backtrace:: create (int, backtraceMap) function pointer is obtained by dlsym, and Native Stack of all threads of a parent process is obtained by calling the function pointer to designate the parent process and threads.
And 206, obtaining the katon context information by utilizing the subprocess according to the information contained in the output stream and the stack information of the preset type.
For example, the sub-process may assemble or aggregate the obtained incomplete katon context information, the kernel Stack, and the Native Stack to obtain the complete katon context 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 cartoon 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, the acquired other stack information of the father process is combined to obtain complete cartoon context information, the complete cartoon context information is transmitted to the father process, and then the father process is written into a local file and reported, so that the multiprocess scheme not only can break through the system limit to acquire more comprehensive cartoon context information, help to accurately position and solve the cartoon problem, but also can effectively reduce or even avoid negative effects such as crashing or secondary cartoon on the preset application program.
Based on the above embodiment, optionally, the version number of the android operating system is lower than a preset version number, and the preset version number may be freely set, for example, 8.0 version. At present, in worldwide, especially third world countries, many people still use low-end intelligent terminal equipment which is low in cost and not advanced enough in hardware facilities, because the complexity of application programs has higher and higher requirements on hardware resources, the probability of the application programs to be blocked or even unresponsive on a low-end machine type is higher, the version of an operating system commonly installed on the low-end machine type is lower, and based on factors such as compatibility and performance, the multi-process scheme can be adopted for collecting the blocking information of the application programs aiming at the low-version operating system, so that negative effects such as crashing or secondary blocking and the like on preset application programs are reduced or even avoided. For the high-version operating system, the implementation can be realized by adopting the related technical scheme adopted in the first embodiment, namely, the katon context information is directly acquired through the process of the preset application program, so that the information acquisition efficiency can be improved, and the katon problem can be conveniently and timely analyzed.
