The following describes in detail, by means of specific embodiments and application scenarios thereof, an inter-process communication method, a system, an apparatus, an electronic device and a medium provided in the embodiments of the present application with reference to the accompanying drawings.

Currently, in a system of a mobile terminal, information transfer between application programs is realized through inter-process communication. Inter-process communication is a communication way of sharing messages between one process and another, and is mainly used for message passing between different processes in a computer system. The process is the minimum unit of computer resource allocation, and each process has own virtual address space and is isolated from the virtual address spaces of other processes; that is, one process can only access its own virtual address space, and cannot access the virtual address space of the other process.

In order to enable the different processes to access and coordinate with each other, the operating system of the mobile terminal provides various inter-process communication mechanisms, mainly including broadcasting, message queues, memory sharing, content Provider (i.e., content Provider), and android interface definition language (Android Interface Definition Language, AIDL), etc.

However, the existing inter-process communication mechanisms all depend on unified resources and communication links of the system, and all processes need to transmit information through the common inter-process communication links of the system one by one according to time sequence. This can have the problem that a large number of applications delay receiving cross-process information when there is a shortage of system memory resources, system stuck, or even if there is no shortage of system resources, there is too much information to be processed on the system inter-process communication link. This results in inefficient inter-process communication.

In order to solve the above problems, embodiments of the present application provide an inter-process communication method, system, device, electronic apparatus, and medium. The inter-process communication method provided by the embodiment of the application can be applied to the scene of information transmission among different processes.

In the inter-process communication method provided in the embodiment of the present application, a first communication link may be established when at least two first processes of a first process type have inter-process communication, where the first communication link is a link for communication between processes of the first process type; and performing inter-process communication between at least two first processes via the first communication link. By the scheme, the exclusive communication link can be established for the processes of the same type with the inter-process communication so as to be used for executing the inter-process communication among the processes of the same type, so that all the processes can be prevented from being crowded on the inter-process communication link of the system, the time for receiving the inter-process information by the application program can be shortened, and the inter-process communication efficiency is improved.

It should be noted that, in the inter-process communication method provided in the embodiment of the present application, the execution body may be an inter-process communication device, an electronic device, or a functional module in the electronic device. In some embodiments of the present application, an electronic device executes an inter-process communication method as an example, which illustrates the inter-process communication method provided in the embodiments of the present application.

Fig. 1 shows a flowchart of an inter-process communication method provided in an embodiment of the present application. As shown in fig. 1, the inter-process communication method provided in the embodiment of the present application may include the following steps 101 and 102.

Step 101, the electronic device establishes a first communication link in case there is inter-process communication of at least two first processes of the first process type.

Wherein the first communication link is a link for communication between processes of the first process type.

In this embodiment of the present application, the at least two first processes are running processes.

It should be noted that, one application running in an electronic device generally corresponds to one process, and in a very small number of scenarios, two processes may also be corresponding.

Optionally, in this embodiment of the present application, the first process type may be any process type, such as a music type, a video type, a navigation type, an input method type, or an instant messaging type.

Alternatively, in the embodiment of the present application, the process type of a process may be determined by the electronic device according to the application package name corresponding to the process.

For example, if the application package name corresponding to a process is "XX navigation", the electronic device may determine that the process type of the process is a navigation class according to the application package name.

Optionally, in this embodiment of the present application, there is inter-process communication between the at least two first processes, that is, at least two processes in the at least two first processes are performing inter-process communication.

For example, assuming that the at least two first processes include a process a, a process b, a process c, and a process d, the at least two first processes can be considered to have inter-process communication when the process a and the process b are performing inter-process communication or when the process a and the process b are performing inter-process communication and the process c and the process d are performing inter-process communication.

Alternatively, in the embodiment of the present application, the first communication link may be a dedicated link for communication between processes of the first process type.

Optionally, in this embodiment of the present application, the first communication link is an inter-process communication link, and may specifically be a communication pipe or a message queue.

For example, as shown in fig. 2, in the case where it is detected that there is an inter-process communication between the process 1 and the process 2 of the first process type (i.e., the at least two first processes), the electronic device may first open up a process area 21 of the first process type separately in the system kernel space for establishing the first communication link. Then, as shown in fig. 3, the electronic device can individually establish the first communication link 22 for communication between processes of the first process type based on the process 1 and the process 2 in the process area 21, so that the process 1 and the process 2 can directly perform transmission of communication information through the first communication link 22 without queuing to transmit communication information on the common inter-process communication link 23. In this way, the efficiency of inter-process communication between processes of the same type can be improved.

Alternatively, in the embodiment of the present application, as shown in fig. 4 in conjunction with fig. 1, the above step 101 may be specifically implemented by the following step 101 a.

Step 101a, when at least two first processes of the first process type have inter-process communication, and there is more than or equal to a first amount of information to be processed on the inter-process communication link of the system, the electronic device establishes a first communication link.

In this embodiment of the present application, the inter-process communication link of the system, that is, the default or preset inter-process communication link of the system, each process running in the electronic device may perform inter-process communication through the inter-process communication link of the system.

In this embodiment of the present application, the information to be processed is communication information to be sent or received by a process that performs inter-process communication.

Alternatively, in the embodiment of the present application, the first number may be preset for the system, or may be set according to actual use requirements. It should be noted that, when the first amount of information to be processed exists on the inter-process communication link of the system, it may be considered that more information to be processed exists on the inter-process communication link of the system, and at this time, transmission of the process communication information in queuing may be blocked, thereby causing delay of inter-process communication.

Exemplarily, assume that a music application 1 and a music application 2 are installed in the electronic device, and that there is no resource for song a in the music application 1, resulting in that song a cannot be played; in order not to affect the user experience, the user may cross-process query whether the music application 2 has the resource of song a, and if the music application 2 has the resource of song a, the user may jump to the music application 2 to play song a.

However, in the inter-process communication of the related art, when the system resources are intense and the information to be processed existing on the inter-process communication link of the system is greater than or equal to the first number, the process a corresponding to the music application 1 may not be able to timely communicate with the process B corresponding to the music application 2. In this embodiment of the present application, the electronic device may establish a new communication link (i.e. the first communication link) for the process a and the process B to transmit communication information, so as to determine whether the music application 2 has the resource of the song a, without queuing on the system inter-process communication link, so that the delay of inter-process communication may be reduced.

Optionally, in the embodiment of the present application, when the number of pieces of information to be processed on the inter-process communication link of the system is smaller than the first number, it may be considered that the number of pieces of information to be processed on the inter-process communication link of the system is smaller, and at this time, the electronic device may also need not to establish the first communication link, and still use the inter-process communication link of the system to perform inter-process communication.

In this embodiment of the present application, the electronic device may establish the first communication link only when the first amount of information to be processed exists on the inter-process communication link of the system, so as to alleviate blocking of the inter-process communication link of the system, that is, the electronic device may determine whether to establish the first communication link according to the blocking condition of the inter-process communication link of the system, so that performance and power consumption of inter-process communication may be balanced.

Step 102, the electronic device performs inter-process communication between at least two first processes through the first communication link.

Optionally, in the embodiment of the present application, the electronic device may directly send the cross-process information transmitted between the at least two first processes to the first communication link, so as to perform inter-process communication between the at least two first processes.

Alternatively, in the embodiment of the present application, as shown in fig. 5 in conjunction with fig. 1, the above step 102 may be specifically implemented by the following steps 102a and 102 b.

In step 102a, the electronic device runs a third process on the first communication link in case at least two second processes of the at least two first processes comprise the first dependency library.

Wherein the third process includes only the first dependency library.

In this embodiment of the present application, the at least two second processes may be part or all of the at least two first processes.

It should be noted that, applications of the same type typically have the same implementation of functions, and implementing the same functions typically has the same code resources or dependency libraries, etc. The dependency library is a complete repository created by the tenant that introduces dependencies in the setup page of the project and uses the tenant library. Roles in the repository include cloud repository, code repository, branch management, document upload, view/download, and release software packages, the storage directory structure of the software package repository file repository.

Alternatively, in embodiments of the present application, a process may include at least one dependency library, each for supporting implementation of a function.

Optionally, in an embodiment of the present application, the first dependency library is used to support implementation of a first function.

Optionally, in this embodiment of the present application, the first function may be any function that is commonly owned by all application programs corresponding to the at least two second processes; for example, the function may be any possible function such as a play function or a download function.

Optionally, in this embodiment of the present application, after the electronic device runs the third process on the first communication link, the first dependency library included in each second process of the at least two second processes may be deleted, that is, the electronic device may separately pull the first dependency library from each second process, so as to save a system storage space.

Optionally, in the embodiment of the present application, after the electronic device runs the third process on the first communication link, the first dependency library included in each second process may be further reserved.

Optionally, in an embodiment of the present application, the third process may be configured to share the first dependency library with each of the second processes.

Illustratively, as shown in fig. 6, assuming that the at least two second processes include a process 1 and a process 2, and that the process 1 and the process 2 each include a dependency library a (i.e., the first dependency library described above), the electronic device may run a process a (i.e., the third process) including the dependency library a on the first communication link to share the dependency library a with the process 1 and the process 2, while deleting the dependency library a included in the process 1 and the process 2. Thus, the electronic device can draw a plurality of dependency libraries A in the process into one dependency library A so as to reduce the system memory.

Step 102b, the electronic device performs inter-process communication between at least two second processes through the third process.

Optionally, in the embodiment of the present application, after the electronic device runs the third process, each of the at least two second processes may use the first dependency library in the third process to perform a function call, so that the electronic device may directly perform inter-process communication between the at least two second processes in the third process.

Optionally, in the embodiment of the present application, the electronic device may store the identifier of each second process in the third process, so as to facilitate accurate communication information transfer during the process of executing inter-process communication between the at least two second processes.

Alternatively, in the embodiment of the present application, the identifier of a process may be any possible identifier, such as a package name or a name abbreviation, of an application program corresponding to the process.

For example, as shown in fig. 7, assuming that the at least two second processes include a process 1 and a process 2, and the third process is a process a, the electronic device may store the identifier of the process 1 and the identifier of the process 2 in the process a in advance, so as to accurately determine the transfer object of the communication information in the process of transferring the communication information by the process 1 and the process 2.

Optionally, in the embodiment of the present application, the electronic device may further store a result mapping table of the at least two second processes in the third process, and if one second process of the at least two second processes needs certain result data, the result mapping table may be directly obtained from the result mapping table.

In the embodiment of the present application, in the case where the at least two second processes include the first dependency library, the electronic device may directly perform inter-process communication between the at least two second processes through the third process including only the first dependency library running on the first communication link, so that the process of inter-process communication may be simplified.

Optionally, in an embodiment of the present application, the inter-process communication between the at least two first processes may include: and network data communication between a fourth process and a fifth process in the at least two first processes. Illustratively, in connection with fig. 1, as shown in fig. 8, the above-described step 102 may be implemented specifically by the following steps 102c and 102 d.

Step 102c, the electronic device sends a network data request message corresponding to the fourth process through the first communication link.

The network data request message is used for requesting to acquire the first network data required by the fourth process, and the network data request message includes the identifier of the fifth process.

Alternatively, in the embodiment of the present application, the fourth process and the fifth process may be: any two processes of network data communication exist in the at least two first processes.

In addition, in the process of executing inter-process communication, the electronic device may call a system resource besides a resource inside a process, for example, call a network channel resource to share to perform inter-process communication between multiple processes of the same type. When network data requests are involved between processes of the same type, some of the same network data, e.g., music songs or trade names, etc., are also typically requested.

In this embodiment of the present application, the identifier of the fifth process may be used for the electronic device to determine the fifth process.

Optionally, in an embodiment of the present application, the identifier of the fifth process may be carried in an encapsulation parameter of the network data request message.

Optionally, in the embodiment of the present application, the electronic device may obtain the identifier of the fifth process through invoking a system interface.

Optionally, in the embodiment of the present application, the electronic device may send the network data request message to a server corresponding to the fourth process through the first communication link and the system network model, so as to request to acquire the first network data.

Alternatively, in the embodiment of the present application, the system network model may be a network seven-layer model, where the network seven-layer model refers to an open system interconnection (Open System Interconnect, OSI) reference model, which divides network communications into seven layers, each layer having different functions and protocols, and from top to bottom: an application layer, a network representation layer, a session layer, a transport layer, a network layer, a data link layer, a physical layer.

Step 102d, the electronic device distributes the first network data to the fourth process and the fifth process, respectively, when receiving the first network data.

It should be noted that, since the fourth process and the fifth process have the same process type, the first network data is also the network data required by the fifth process with a high probability; in the related art, network data required by each process needs to send a network data request message to request for acquisition, and after acquiring the network data requested by one network data request message, the electronic device only sends the network data to the corresponding process.

Optionally, in the embodiment of the present application, the electronic device distributes the received first network data to the fourth process and the fifth process, respectively, without sending the received first network data to the fifth process through the fourth process, so as to indirectly implement inter-process communication between the fourth process and the fifth process through network access.

Optionally, in the embodiment of the present application, the electronic device may distribute the first network data to the fourth process and the fifth process through a network representation layer of the network seven-layer model.

Optionally, in this embodiment of the present application, the fourth process may also include an identifier of the fifth process, and when the presentation layer distributes the first network data, the fifth process may be accurately determined according to the identifier of the fifth process, and the first network data may be distributed to the fifth process.

For example, as shown in fig. 9, assuming that the application 1 corresponding to the process 1 (i.e. the fourth process) needs to transfer network result information (i.e. the first network data) to the application 2 corresponding to the process 2 of the same type (i.e. the fifth process), the electronic device may first call the system interface to obtain the identifier of the process 2, and then, when sending the network data request message corresponding to the process 1, may carry the identifier of the process 2 in the network data request message; in this way, when the network result information sent by the server corresponding to the process 1 is received, the network representation layer in the system network model can find the process 2 to transmit according to the identifier of the process 2 in the process 1, so that the transmission efficiency of the inter-process transmission network data can be greatly improved.

In the embodiment of the present application, the electronic device may indirectly implement the inter-process communication between the fourth process and the fifth process through the initiated network data request, so that the process of inter-process communication may be further simplified.

In the inter-process communication method provided by the embodiment of the application, because the exclusive communication link can be established for the process of the same type with the inter-process communication to be used for executing the inter-process communication among the processes of the same type, all the processes can be prevented from being crowded on the inter-process communication link of the system, so that the time for receiving the inter-process information by the application program can be shortened, and the inter-process communication efficiency is improved.

Optionally, in the embodiment of the present application, as shown in fig. 10 in conjunction with fig. 1, after the step 102, the inter-process communication method provided in the embodiment of the present application may further include the following step 103.

Step 103, the electronic device executes the first processing on the first communication link in case that the processes of the first process type are all terminated.

Wherein the first process includes any one of: deletion processing and closing processing.

Optionally, in the embodiment of the present application, the processes of the first process type terminate running, that is, the electronic device system background does not have the process of the first process type.

Optionally, in the embodiment of the present application, the deleting process deletes the first communication link, and a process area of the first process type in a kernel space of the system.

Optionally, in the embodiment of the present application, the closing process closes the first communication link, and a process area of the first process type in a kernel space of the system.

Optionally, in an embodiment of the present application, closing the first communication link may include: the first communication link is placed in an idle state or a dormant state.

In the embodiment of the present application, in the case where the processes of the first process type all terminate running, the electronic device may perform the deletion process or the closing process on the first communication link, so that when communication between the processes of the first process type is not required, resources of the system may be saved.

The foregoing method embodiments, or various possible implementation manners in the method embodiments, may be executed separately, or may be executed in combination with each other on the premise that no contradiction exists, and may be specifically determined according to actual use requirements, which is not limited by the embodiments of the present application.

The embodiment of the application also provides an inter-process communication system, as shown in fig. 2, which comprises an application layer, a framework layer and a system kernel space. The system kernel space may include a first kernel space 21, the first kernel space 21 being configured to establish a first communication link, the first communication link being an inter-process communication link of a first process type; the application layer may be used to provide services for running applications; the framework layer may be used to determine the flow and interaction between system functions.

In one possible implementation, the first communication link is established in the presence of greater than or equal to a first amount of information to be processed on an inter-process communication link established in the kernel space of the system for communication between any of the processes.

In a possible implementation manner, the first communication link is operable to: a third process comprising a first dependency library, and at least two second processes of the first process type. At least two second processes can communicate with each other through the third process, and the second processes comprise the first dependency library.

In a possible implementation manner, the system may further include a network representation layer, where the fourth process and the fifth process of the first process type run on the first communication link. The first communication link may be configured to send a network data request message corresponding to the fourth process, where the network data request message is used to request to obtain first network data required by the fourth process, and the network data request message includes an identifier of the fifth process; the network representation layer may be configured to distribute the first network data to the fourth process and the fifth process, respectively, upon receipt of the first network data.

In a possible implementation manner, in a case where the processes of the first process type all terminate running, a first process may be performed on the first communication link, where the first process includes any one of the following: deletion processing and closing processing.

For a specific description of the embodiments of the present application and the technical effects achieved by each technical feature, reference may be made to the related description in the foregoing method embodiments, and in order to avoid repetition, a description is omitted herein. According to the inter-process communication method provided by the embodiment of the application, the execution subject can be an inter-process communication device. In the embodiment of the present application, an inter-process communication device executes an inter-process communication method by using an inter-process communication device as an example, and the inter-process communication device provided in the embodiment of the present application is described.

As shown in fig. 11, an embodiment of the present application provides an inter-process communication device 110, where the inter-process communication device 110 may include a setup module 111 and an execution module 112.

The establishing module 111 may be configured to establish a first communication link when at least two first processes of a first process type have inter-process communication, where the first communication link is a link for communication between processes of the first process type. An execution module 112 may be configured to perform inter-process communication between the at least two first processes via the first communication link.

In a possible implementation manner, the establishing module 111 may be specifically configured to establish the first communication link when at least two first processes of the first process type have inter-process communication, and there is greater than or equal to a first amount of information to be processed on a system inter-process communication link.

In a possible implementation manner, the execution module 112 may be specifically configured to execute a third process on the first communication link, where at least two second processes of the at least two first processes include a first dependency library, and the third process includes only the first dependency library; and performing inter-process communication between the at least two second processes through the third process.

In one possible implementation manner, the inter-process communication between the at least two first processes includes: and network data communication between a fourth process and a fifth process in the at least two first processes. The execution module 112 may be specifically configured to send, through the first communication link, a network data request message corresponding to the fourth process, where the network data request message is used to request to obtain first network data required by the fourth process, and the network data request message includes an identifier of the fifth process; and distributing the first network data to the fourth process and the fifth process, respectively, upon receipt of the first network data.
