The display screen may be a touch screen, such as a capacitive screen or an electronic screen, and is configured to display interface information of an application corresponding to a foreground process, and also may be configured to detect a touch operation applied to the display screen, and generate a corresponding instruction, such as a switching instruction for performing foreground and background applications.

Those skilled in the art will appreciate that the architecture shown in fig. 1 is a block diagram of only a portion of the architecture associated with the subject application, and does not constitute a limitation on the electronic devices to which the subject application may be applied, and that a particular electronic device may include more or less components than those shown, or may combine certain components, or have a different arrangement of components. For example, the electronic device further includes a network interface connected via the system bus, where the network interface may be an ethernet card or a wireless network card, and the like, and is used for communicating with an external electronic device, such as a server.

In one embodiment, as shown in FIG. 2, a partial architecture diagram of an electronic device is provided. The architecture system of the electronic device includes a JAVA space layer 21, a local framework layer 22, and a Kernel space layer 23. Policy applications 210 may be included on the JAVA space layer 21, and the electronic device may initiate a freeze and thaw policy for each application through the policy applications 210, so as to implement a freeze and thaw operation for each application in the electronic device. For example, the policy application 210 determines an application consuming power in the background, and initiates a freeze operation on the application consuming power in the background. The local framework layer 22 includes a resource priority and restriction management module 220 and a platform freeze management module 222. The electronic device can maintain the priority of the application program and the corresponding resource group in real time through the resource priority and restriction management module 220, and adjust the priority and the resource group of the application program according to the requirement of the upper layer, thereby achieving the effects of optimizing performance and saving power consumption. The electronic device may allocate, by using the platform freezing management module 222, the task that can be frozen in the background to the freezing layers corresponding to the preset different layers according to the length of the freezing time, where optionally, the freezing layers may include: CPU limited sleep mode, CPU frozen sleep mode, process deep frozen mode.

Through the above framework, the process processing method in each embodiment of the present application can be realized.

FIG. 3 is a flow diagram of a process handling method in one embodiment. As shown in fig. 3, the process control method includes steps 302 to 308. Wherein:

step 302, if a shutdown signal corresponding to the target process is detected, detecting whether the target process is in a frozen state.

An Application (APP) is software written for a certain Application purpose in an electronic device, and the electronic device can implement a service required by a user through the APP. For example, a user may play a game through a game-like application, may watch a video through a video-like application, may play music through a music-like application, and the like. The application program can be divided into a foreground application program and a background application program according to the running state. The foreground application program refers to an application program running in the foreground of the electronic device, and the foreground application program can be displayed on the foreground and can interact with a user. Background applications refer to applications that run in the background of an electronic device, and background applications generally cannot be displayed in the foreground and implement an interactive process with a user.

Generally, an application operation of an application program is collectively performed by one or more processes (processes), which are one-time running activities of the program in a computer on a certain data set and are basic units for resource allocation and scheduling of a system. Meanwhile, one process can correspond to one or more threads, and the threads are a single sequential control flow in a program and are relatively independent and schedulable execution units in the process. The processes may include a foreground process, i.e., a process running in the foreground of the electronic device, and a background process, i.e., a process running in the background of the electronic device. The electronic equipment can control the switching of the foreground process and the background process, the foreground process can be switched to the background process to run, and the background process can also be switched to the foreground process to run. Specifically, the management of the process may be implemented by a process pool, and process identifiers corresponding to one or more processes may be stored in the process pool. The process pool may include a foreground process pool and a background process pool, the foreground process pool includes a process identifier corresponding to a foreground process, and the background process pool includes a process identifier corresponding to a background process. When detecting that the running states of the foreground process and the background process are changed, the process pool can correspondingly add or delete the process identification which is changed. For example, the process identifier of process a is "0123", and when it is detected that process a is changed from a background process to a foreground process, the process identifier of process a, which is "0123", can be removed from the background process pool and added to the foreground process pool.

In one embodiment, a shutdown signal refers to a signal that initiates a shutdown operation for a process. Generally, an application program of the application layer of the electronic device may initiate a shutdown signal, and after receiving the shutdown signal, the process may exit from running according to the shutdown signal. After the process exits, resources such as a processor and a memory of the terminal are not occupied. Taking the terminal of the Android system as an example, an application program in the terminal application layer may trigger to initiate a close signal to a process by calling an Android. It can be understood that, in the present application, the process processing method is described by taking an Android Operating System as an example, but the process processing method of the present application is not limited to be implemented in the Android System, and may also be applied in Operating systems such as ios (iphone Operating System), saiban, Windows, and MAC OS (MAC Operating System).

And step 304, if the target process is detected to be in the frozen state, unfreezing the target process.

In particular, processes may be frozen, and processes in the frozen state are not shut down, but are temporarily not running. The frozen process is generally processed in the operating system, and is controlled to enter an uninterruptible sleep state through a function body. A process in such an uninterruptible sleep state, even if woken up, will immediately resume in the uninterruptible sleep state due to the presence of the body of the function. Therefore, the process in the frozen state cannot receive the signal and cannot process the signal. That is, the process in the frozen state does not occupy the processor resource for running, but still occupies the resources such as the memory and hardware of the electronic device. The resource priority and restriction management module in the local framework layer of the electronic device can mark the state of the process, control the frozen state of the process through the corresponding mark, and know whether the process is in the frozen state or not by reading the state mark of the process.

After an application program in the application layer of the electronic device initiates a shutdown signal, the kernel layer of the electronic device may receive the shutdown signal, and then determine whether the process is in a frozen state by reading the resource priority and the constraint management module of the local framework layer. The closing signal can be initiated by a third party application program or a system application program. For example, the user may select a process to be killed through the third-party application program, and then initiate a shutdown signal to the process selected by the user through the third-party application program. The electronic equipment can also automatically trigger the killing of the background process according to the running condition, and when the background process meets the killing condition, a system application program of the electronic equipment automatically triggers to send a closing signal to the background process.

Step 306, sending a close signal to the target process.

And if the target process is judged to be in the frozen state, the electronic equipment can unfreeze the target process through the local framework layer. Meanwhile, the kernel layer of the electronic device sends a closing signal to the target process. If the target process is in the frozen state when the shutdown signal is sent, the target process cannot receive the shutdown signal, and the shutdown signal is added into a signal processing queue corresponding to the target process. And after the target process is unfrozen, the target process acquires the processing signal from the signal processing queue and processes the processing signal.

The signal transmitted in the electronic equipment is provided with a sending process identifier and a receiving process identifier, then the process for sending the signal is searched through the sending process identifier, and the process for receiving the signal is searched through the receiving process identifier. Specifically, the electronic device may search for the target process according to the receiving process identifier carried in the closing signal, and then send the closing signal to the target process corresponding to the receiving process identifier.

And 308, if the target process is unfrozen, closing the target process according to the closing signal.

When the target process is unfrozen, the unfrozen target process can be placed in a non-freezing state, and the process in the non-freezing state can not be frozen any more. After the target process is thawed, the signal may be received and processed. The target process may obtain a close signal through the signal processing queue and close according to the close signal.

In the process processing method provided in the above embodiment, when a shutdown signal corresponding to the target process is detected, if it is detected that the target process is in a frozen state, the target process is thawed. And processing the closing signal through the unfrozen target process. Therefore, the target process is in a frozen state instantly, and the closing signal can be processed in time. Under the condition of insufficient equipment resources, the target process can also receive and respond to the closing signal in time and release the equipment resources in time, so that the running efficiency of the equipment is ensured, and the resource utilization rate of the equipment is improved.

Fig. 4 is a flowchart of a process handling method in another embodiment. As shown in fig. 4, the process processing method includes steps 402 to 420. Wherein:

and 402, acquiring the resource occupancy rate of the electronic equipment, and acquiring the target process according to the resource occupancy rate.

In one embodiment, the electronic device is operating with limited resources for application processing. Therefore, the electronic device needs to continuously release the memory during the operation process, so that the effective operation of the application can be ensured. The resource refers to software or hardware resources that the electronic device must use when processing the application event, such as a memory and hardware resources of the electronic device. The resource occupancy rate refers to a resource occupancy proportion of the electronic device, generally refers to a proportion of occupied resources to total resources, and can be expressed in a percentage form. For example, if the total memory of the device has 128GB and the memory already occupied has 56GB, the resource occupancy of the device can be expressed as the memory occupancy, and the obtained memory occupancy is 43.75%.

The method comprises the steps of establishing a corresponding relation between the resource occupancy rate and process identification of a process in advance, obtaining corresponding target process identification according to the resource occupancy rate, and obtaining corresponding target process according to the target process identification. And establishing a corresponding relation between the resource occupancy rate and the process priority, then acquiring the corresponding target priority according to the resource occupancy rate of the electronic equipment, acquiring a target process identifier corresponding to the target priority, and acquiring the corresponding target process according to the target process identifier. For example, the memory occupancy rate of the electronic device is divided into three levels, such as 20-40%, 40-70%, 70-100%, and the like, the process is divided into five priorities, such as level 1, level 2, level 3, level 4, level 5, and the like, and the importance of the process decreases from level 1 to level 5. And then establishing a corresponding relation between the memory occupancy rate and the priority of the process, wherein 20-40% of the memory occupancy rate corresponds to 4 levels and 5 levels of the process, 40-70% of the memory occupancy rate corresponds to 3 levels, 4 levels and 5 levels of the process, and 70-100% of the memory occupancy rate corresponds to 2 levels, 3 levels, 4 levels and 5 levels of the process. Assuming that the memory occupancy rate in the electronic device is 50%, the priorities of the corresponding processes are 3, 4, and 5, and the processes with the priorities of 3, 4, and 5 are obtained as the target processes.

The corresponding relation can be stored in a list form, the electronic device can count the resource occupancy rate once at intervals, read the corresponding target process identification from the list according to the resource occupancy rate obtained by counting, and then acquire the corresponding target process according to the target process identification. For example, the electronic device may read the resource occupancy rate every 5 minutes, and then obtain the corresponding target process according to the resource occupancy rate.

Step 404, a shutdown signal is initiated to the acquired target process.

The shutdown signal may be initiated by a third party application or by a system application. The initiated close signal may include, but is not limited to, a sending process identifier, a receiving process identifier, and the like. The electronic device may look up the target process by receiving the process identification and then send the shutdown signal to the target process. For example, a signal may be sent to the target process through a function int send _ sig _ info (int sig, struct siginfo info, struct task _ struct).

Step 406, if a shutdown signal corresponding to the target process is detected, detecting whether the target process is in a frozen state.

Step 408, if it is detected that the target process is in the frozen state, acquiring a frozen duration corresponding to the target process, where the frozen duration represents a time interval from the time when the target process enters the frozen state to the current time.

When the process enters the frozen state, the electronic equipment simultaneously records the time when the process enters the frozen state, then monitors the state of the electronic equipment in real time, and when the process exits the frozen state, simultaneously records the time when the process exits the frozen state. Therefore, the electronic equipment can manage the state of each process, and the state of the process at each moment can be read through the state corresponding to the process recorded by the electronic equipment. The freezing duration is a time interval from the time of identifying the target process entering the freezing state to the current time, and specifically refers to a time interval from the time of entering the freezing state to the current time. For example, if the time when the process enters the frozen state at this time is 12 o 'clock 10 min 02 sec, and the current time is 12 o' clock 14 min 10 sec, the obtained freezing time length is 4 min 08 sec.

Specifically, the electronic device may read a current state of the target process, and if the target process is currently in a frozen state, may read a time at which the target process enters the frozen state this time, and then obtain a current time, and calculate a corresponding frozen duration according to the time at which the target process enters the frozen state and the current time. For example, in the Android system, the current time can be obtained through a function SimpleDateFormat ("yyyy-MM-dd hh: MM: ss"), and then the extreme freezing duration is determined according to the read time of entering the freezing state.

And step 410, if the freezing time length is greater than the time length threshold value, unfreezing the target process.

It can be understood that the frozen duration may reflect a duration of the process entering the frozen state at this time, and if the process is not thawed after being in the frozen state for a long time, which indicates that the process is not in the running state for a long time, the process may be considered as an unimportant process, and the process may be closed. The duration threshold is a value of the duration for screening the target process, and can be set as required. When the freezing duration of the target process is greater than the duration threshold, the probability that the target process is restarted by a user or a system is considered to be relatively low, the target process can be unfrozen and then closed; and if the freezing duration of the target process is less than the duration threshold. The probability that the user or the system restarts the target process is considered to be relatively high, and the current state of the target process can be continuously maintained.

For example, the time threshold is 1 hour, and if the freezing time of the target process exceeds 1 hour, the target process may be thawed and then the thawed target process may be shut down. If the freezing time of the target process is 5 minutes, which means that the time for the target process to enter the freezing state is 5 minutes, it is considered that the probability that the target process is started again by the user or the system is high, and the state of the target process can be continuously maintained.

Step 412, adding the close signal to a signal processing queue corresponding to the target process, where the signal processing queue includes one or more processing signals for processing the target process.

Each process may have a signal processing queue, which may be a stack space, that includes one or more processing signals for processing the target process, each processing signal indicating processing of a process. Specifically, the signal processing queue corresponding to the process may be a chain queue arranged in sequence, and may be described by a data structure. For example, in the signal processing queue list, it can be described by a signaling data structure. The signaling data structure may include three data, i.e., head, tail, signal, etc., where head is used to point to the first processed signal, tail is used to point to the next pointer of the last processed signal, and signal is used to describe the signal set in the signal processing queue.

And step 414, if it is detected that the target process is unfrozen, acquiring a signal processing queue corresponding to the target process, and sequencing the processing signals according to the signal initiation time.

When the target process is in the frozen state, the target process cannot receive the signal or process the signal. The processing signals received by the target process are stored in the signal processing queue, and then the processing signals in the signal processing queue are processed after the target process is awakened. When the target process is unfrozen, the target process can be operated in the electronic device. The target process acquires a corresponding signal processing queue, and the processing signals in the signal processing queue are sequenced according to signal initiation time, wherein the signal initiation time is the time for initiating the processing signals. The processing signals can be generally arranged according to the sequence of the signal initiation time from first to last, so that the processing signal at the first position of the queue can be preferentially acquired for processing during processing. The processing signals can also be arranged according to the sequence from the beginning of the signal to the end of the signal, and the processing signals at the tail of the queue can be preferentially acquired for processing during processing. In this embodiment, the arrangement order of the signal processing queues and the processing sequence are not specifically limited. For example, the signal processing queue includes three processing signals, the signal initiation time corresponding to the signal a is 12:16, the signal initiation time corresponding to the signal B is 13:22, and the signal initiation time corresponding to the signal C is 13: 50. The signal processing queue may be arranged in the order of signal a, signal B and signal C.

And step 416, sequentially processing the processing signals in the sorted signal processing queue.

In general, to avoid missing information, after being defrosted, the target process processes the unprocessed processing signals during the freeze period, that is, sequentially processes the processing signals in the sorted signal processing queue. It is understood that after the target process is thawed, all the processing signals in the signal processing queue may not be processed, and only a part of the processing signals may be obtained for processing. Optionally, the processing signal is obtained from the sorted signal processing queue according to the signal initiating object, and the obtained processing signal is processed. The signal initiating object refers to an object initiating a processing signal. For example, only the processing signal initiated by the system application may be processed, or only the processing signal whose corresponding signal initiation object is the same as the signal initiation object of the shutdown signal may be processed.

In one embodiment, the processing signals may also be obtained from the sorted signal processing queues according to the signal priorities of the processing signals, and the obtained processing signals are processed. Wherein the signal priority represents an important procedure for processing the signal. For example, the signal priority may be set according to the type of the processing signal, the signal priority of the processing signal corresponding to the instant message is higher, and the signal priority of the processing signal corresponding to the non-instant message is lower. And the processing signals are acquired according to the signal priority, and only the processing signals with higher priority are processed after the target process is unfrozen, so that the resource of equipment is saved.

In step 418, the target process is closed according to the close signal.

Specifically, the target process is closed according to the closing signal, and after the target process is closed, all threads corresponding to the target process can be closed, so as to avoid zombie processes. After the target process is closed, the target process can be set to be in the non-freezing state, and under the non-freezing state, the target process cannot be frozen again, so that the target process is prevented from entering the freezing state again to cause resource occupation. Alternatively, the duration of the unfrozen state may also be set, timed from the time the target process is turned off, within which duration the target process is set to the unfrozen state. A corresponding relationship between the process priority and the duration may also be established, where the higher the process priority is, the shorter the corresponding duration is. The corresponding duration is obtained according to the process priority of the target process, then timing is started from the time when the target process is closed, and the target process is set to be in the non-freezing state within the duration.

And step 420, acquiring the dependent process dependent on the target process, and closing the dependent process according to the closing signal.

In one embodiment, dependencies indicate the relationship that a process needs to utilize data of another process or processes to successfully implement execution of the one process. There are two processes of dependency relationship, respectively a depended process and a dependent process. For example, the process a depends on the process B, or the process B is depended on the process a, that is, the process a needs to use the data of the process B to execute the process a, at this time, the process a is a process depending on the process B, and the process B is a process depended on by the process a. Specifically, in the embodiment of the present application, a dependent process refers to a process that runs in dependence on a target process.

The dependency between processes is not always constant, but changes in real-time. The electronic equipment can record the dependency relationship among the processes, after the target process is closed, a background process dependent on the target process is searched from the recorded dependency relationship to serve as the dependent process, and the dependent process is closed according to the closing signal. In particular, the interdependence between two processes is based on the need for them to communicate with each other. Therefore, acquiring the dependent process corresponding to the target process includes: and acquiring a background process with a communication relation with a foreground process as a dependent process. In an operating system, the interaction mechanism between processes is mainly divided into a synchronization mechanism and a communication mechanism.

The communication mechanism comprises Socket, Binder, shared memory and the like. Binder Communication is an efficient IPC (Inter-Process Communication) mechanism implemented in an Android system, and is a client-server Communication structure. The client and the server define a corresponding proxy interface, when the client calls a method in the proxy interface, the method of the proxy interface packages parameters of the client into a Parcel object, and then the proxy interface sends the Parcel object to a Binder driver in the kernel layer. The server can read the request data in the Binder driver, then analyze and process the Parcel object, and return the processing result. Socket communication can be used for carrying out communication connection on two network application programs, so that data exchange of the application programs on the network is realized. Specifically, local inter-Process communication can uniquely identify a Process through PID (Process Identity), but communication among network processes is impossible. In network communication, an IP (Internet Protocol, Protocol for interconnection between networks) address can uniquely identify a host in a network, and a "Protocol + port" can uniquely identify a process in the host, so that in Socket communication, a process is typically uniquely identified in the form of "IP address + Protocol + port". Shared memory is a very efficient way to allow two unrelated processes to access the same logical memory, and shared memory is a very efficient way to share and transfer data between two running processes, and memory shared between different processes is usually arranged as the same physical memory.

Furthermore, acquiring the dependent process corresponding to the target process includes at least one of the following manners: acquiring a background process having a socket communication relation with a target process as a dependent process; acquiring a background process having a binder communication relationship with a target process as a dependent process; and acquiring a background process sharing the memory with the target process as a dependent process.

The process processing method provided in the foregoing embodiment acquires the target process according to the resource occupancy rate of the electronic device, and initiates the shutdown signal to the acquired target process. And when a closing signal corresponding to the target process is detected, if the target process is detected to be in a frozen state, unfreezing the target process according to the freezing time length of the target process. And closing the unfrozen target process and the dependent process according to the closing signal. Therefore, the target process is in a frozen state instantly, and the closing signal can be processed in time. Under the condition of insufficient equipment resources, the target process can also receive and respond to the closing signal in time and release the equipment resources in time, so that the running efficiency of the equipment is ensured, and the resource utilization rate of the equipment is improved. And under the condition that the target process is closed, closing the dependent process dependent on the target process so as to reduce the occupation of the device resources by the dependent process.

It should be understood that although the steps in the flowcharts of fig. 3 and 4 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
