Detailed Description
The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The data acquisition method provided by the embodiment of the application is described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a data acquisition method, which may be applied to an electronic device. The data acquisition method specifically comprises the following steps:
step 101, start the system state information dumpstate process.
Specifically, the electronic device starts a system state information dumpstate process, which is a preconfigured process.
It should be noted that, in the Android system, the dump state process is an important process for diagnosing system faults and collecting logs, and when the system encounters serious errors, such as system crashes, application crashes and the like, the dump state process can be automatically started to collect relevant log information, so that developers can be helped to quickly locate and eliminate problems. Meanwhile, the dumpstate process can be manually invoked to collect state information of the equipment for problem investigation and performance optimization.
And, the dumpstate process has sys_ptrace authority, which is an authority provided by the Android system and used for allowing one process to access information such as a memory of another process in a debugging mode. Specifically, sys_ptrace may cause one process to signal another process via a system call function ptrace () to obtain or modify information such as registers, memory, stacks, file descriptors, etc. of the process. The Android system closes sys_ptrace authority by default. In the Android system, the dumpstate process has the right.
Step 102, starting a performance analysis tool simpleperf process through the system state information dumpstate process, wherein the performance analysis tool simpleperf process inherits a first authority of the system state information dumpstate process, and the first authority comprises: rights to performance data collection.
Specifically, simpleperf is an Android performance analysis tool, which can help developers to perform performance analysis on application programs on Android devices, so that performance problems and bottlenecks are identified and optimized. In the unot state, the simplef process does not have the permission of performance data acquisition, and the dumpete process has the permission of performance data acquisition, so that the electronic equipment starts the simplef process through the dumpete process, and the simplef process can inherit the permission of performance data acquisition of the dumpete process.
Moreover, the simplef process does not have the system tracking sys_ptrace authority, the dumpstate process has the sys_ptrace authority, and the electronic device starts the simplef process through the dumpstate process, so that the simplef process can inherit the sys_ptrace authority of the dumpstate process.
Furthermore, the authority of the performance data collection may be specifically a security policy configuration file sepiolicy authority. The Security authority of Android can be understood as an implementation manner of Security-Enhanced Linux (SELinux) on an Android system, and is a description and setting of SELinux Security policies for limiting the access of dumpstate processes to system resources.
The SELinux policy realizes the description and setting of specific rights through a security policy configuration file sepolicy. The assigned sepiolicy permissions of the dumpstate process are configured to ensure that the dumpstate process can access the required system resources and services. For example, "allow dumpstate proc _perf: file write" is a rule statement in which "dumpstate" in the rule indicates that the dumpstate process is permitted to perform this operation, "proc_perf: file" indicates that the object to be operated is a proc_perf file, and "write" indicates that the process is permitted to perform a write operation.
The SELinux is a forced access control (MAC system) mechanism, is a security enhancement technology realized on a Linux operating system, and mainly aims to improve the security of the Linux system, and prevents attack of malicious codes and utilization of system loopholes by carrying out fine-grained control on access rights of processes.
And step 103, collecting performance data through the performance analysis tool simpleperf process to obtain target data.
Specifically, the simplepref process inherits the authority of performance data acquisition, so that the simplepref can acquire corresponding target data by performing performance data acquisition, a programmer can be helped to know the execution condition of a program through the target data, the performance bottleneck is found out and optimized, and meanwhile, the problem of the program can be positioned and solved by analyzing the information such as the function call relation, the code block execution condition and the like.
Wherein the performance data that the simpleperf process can collect includes at least one of:
the CPU (Central Processing Unit, CPU) instruction execution times and CPU time occupation;
calling relation, calling times, consumed time and other information of the functions and the code blocks;
stack tracking information for analyzing performance bottlenecks and performance optimizations in the program;
common compiler instructions are executed as follows: cyclic expansion, vectorization and the like;
information such as kernel functions, system calls and the like in a call chain provides support for kernel-level performance analysis;
the CPU cache hit rate and cache service conditions and other information provide support for program optimization;
and the execution conditions of the program on different CPU cores support multi-core parallel performance optimization.
In the above embodiment of the present application, a performance analysis tool simpleaf process is started by starting a system state information dumpstate process, then the performance analysis tool simpleaf process is started by the system state information dumpstate process, and inherits the authority of performance data acquisition of the system state information dumpstate process, and then performance data acquisition is performed by the performance analysis tool simpleaf process, so as to obtain target data. According to the scheme, the simpleperf process is started through the dumplstate process, so that the simpleperf process inherits the permission of performance data acquisition of the dumplstate process, performance data acquisition can be carried out through the simpleperf process, the whole process does not need to acquire root permission of equipment, acquisition of the performance data can be completed without connecting a PC (personal computer) end, and the data acquisition efficiency is improved.
As an alternative embodiment, the performance analysis tool simpleperf process also has a communication interface; the method may further comprise:
and sending the target data to a target application program through the communication interface.
Specifically, the simpleperf process is further configured with a communication interface, such as: socket, thus the simplef process has the capability of using a communication interface such as socket, so that the simplef process can communicate with the target application program, can accept data acquisition parameters sent by the target application program, and can also send the obtained target data to the target application program so as to save the target data to a target position configured by the target application program for user access.
It will be appreciated that the target application is configured with data acquisition parameters, which are command parameters provided to the simpleperf process for acquisition of the required performance data. Because the simplef process is configured with a communication interface, the electronic device can send the data acquisition parameters configured in the target application program to the simplef process, so that the simplef process performs performance data acquisition according to the data acquisition parameters. The data collection parameters may be set in a target application program in a customized manner, which is not limited herein.
In addition, the signature of the platform manufacturer can be configured in the target application program so as to acquire the authority of the attribute of the read-write system.
As an optional embodiment, the step 101 starts a system state information dumpstate process, which specifically includes:
under the condition that the electronic equipment starts a target application program, acquiring a first input of the target application program;
in response to the first input, a system state information dumpstate process is started.
Specifically, the user installs a target application program in the electronic device, the electronic device obtains a second input of the user to the icon of the target application program, the target application program is started, and under the condition that the target application program is started, that is, under the condition that the target application program is operated, the electronic device obtains a first input of the user to the target application program, and in response to the first input, the system state information dumpstate process is started.
It will be appreciated that the target application is a system-level application, is an Android application package (Android application package, apk) file, may be directly installed in the electronic device, and has a User Interface (UI), and the User may perform clicking, double clicking, etc. on the UI of the target application.
It should be noted that, in order to enable the dumpetate process to be started by the target application program, the target application program needs to have a switch for starting the dumpetate process, that is, a system attribute may be added to the Android system, where the system attribute corresponds to a switch, and the target application program may start the dumpetate process by modifying a state (i.e., the first input) of the system attribute.
As an optional embodiment, the step 102 starts a performance analysis tool simpleperf process through the system state information dumpstate process, which specifically includes:
acquiring target parameters in the system state information dumpstate process;
and under the condition that the target parameters are consistent with preset parameters, creating and starting the performance analysis tool simpleperf process through the system state information dumpstate process.
Specifically, the electronic device acquires a target parameter in the dumpstate process, compares whether the target parameter is consistent with a preset parameter, and if so, can create and start a simpleperf process through the dumpstate process; if the target parameter is inconsistent with the preset parameter, no authority is indicated to create the simpleperf process. Specifically, the sub-process of the dumpstate process, i.e., the simpleperf process, can be created by means of a bifurcation function fork.
It should be noted that the target parameter may be account information given when the target application program starts the dump, and the account information is account information of the login target application program.
As an optional embodiment, the step 103 performs performance data collection through the performance analysis tool simpleperf process to obtain target data, which specifically includes:
and under the condition that a performance data acquisition command sent by the target application program is received, performing performance data acquisition through the performance analysis tool simpleperf process to obtain target data.
Specifically, under the condition that a performance data acquisition command sent by a target application program is received, the simplepref process analyzes the data acquisition parameters to acquire corresponding performance data, so that required target data is obtained, a programmer can be helped to know the execution condition of the program through the target data obtained by the simplepref process, the performance bottleneck is found out and optimized, and meanwhile, the problem of the program can be positioned and solved by analyzing information such as a function call relation, the execution condition of a code block and the like.
It will be appreciated that, before performance data collection is performed by the performance analysis tool simpleperf process, the simpleperf process determines whether the application program transmitting the data collection parameters is a target application program. If the application program sending the data acquisition parameters is a target application program, the simpleperf process can acquire performance data according to the data acquisition parameters; and if the application program sending the data acquisition parameters is inconsistent with the target application program, prohibiting the simpleperf process from acquiring the performance data, and ending the flow.
As shown in fig. 2, the above scheme is specifically described below by way of a specific embodiment:
step 201: in the case where the electronic device initiates a target application, the electronic device obtains a first input to the target application.
