Detailed Description
Embodiments of the present application are described below with reference to the accompanying drawings.
At present, a front-end developer can develop a server application in an operation environment based on a programming language, however, a scene of needing a large amount of data transmission exists in the operation environment, and the application performance is low.
In order to solve the technical problems, the application provides a memory sharing method and a related device, wherein in an operating environment based on a first programming language, an executable file based on a second programming language can be loaded through a programming interface, so that memory sharing is realized by using the second programming language, inter-process communication efficiency is improved, and application performance is improved.
The memory sharing method provided by the embodiment of the application can be implemented through computer equipment, and the computer equipment can be terminal equipment or a server, wherein the server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server for providing cloud computing service. Terminal devices include, but are not limited to, cell phones, computers, intelligent voice interaction devices, intelligent home appliances, vehicle terminals, aircraft, and the like. The terminal device and the server may be directly or indirectly connected through wired or wireless communication, which is not limited herein.
In order to facilitate understanding of the technical solution provided in the present application, a method for sharing a memory provided in the embodiments of the present application will be described next with reference to an actual application scenario.
Fig. 1 is a schematic diagram of an application scenario of a memory sharing method according to an embodiment of the present application, where the scenario includes a server 10, and the server 10 may be used as the aforementioned computer device to implement memory sharing in an operating environment based on a first programming language.
In an operating environment based on a first programming language, the server 10 can load an executable file based on a second programming language through a programming interface, the second programming language is a lower-layer programming language than the first programming language, a corresponding shared memory space can be determined for a target memory identifier through the executable file based on the second programming language, data to be shared in a memory of the operating environment is copied to the shared memory space, and because the shared memory space is used for being accessed by a plurality of processes in the operating environment, the processes can share the data by accessing the same data in the shared memory space, so that the data transmission efficiency among the processes is improved, and the application performance is improved.
In addition, the server 10 may store the target memory identifier and the memory area information of the shared memory space in the global variable, so that the target memory identifier and the memory area information of the shared memory space are reserved even if the executable file is executed, the shared memory space is not released, and the stored data is not deleted, so that the access of the processes to the data in the shared memory space is not affected even if the executable file is executed.
Fig. 2 is a flowchart of a memory sharing method provided in the embodiment of the present application, where in this embodiment, a server is used as the computer device to describe the memory sharing method, the memory sharing method may include:
s101, loading an executable file based on a second programming language through a programming interface in a running environment based on a first programming language.
The front-end developer can develop the server application in the running environment based on the programming language, for example, node. Js is a JavaScript running environment based on the Chrome V8 engine, and can be used for developing a high-performance and scalable network application program, and the programming language can be the JavaScript language. The application may be run by a computer device and may include a PC client program, a mobile client program, a daemon program, etc. The computer device allocates computing resources for the applications to execute application-related data processing logic, the computing resources may include processes, each process may include a plurality of threads, and each thread may be configured to execute corresponding data processing logic. The computer device may also allocate memory space for the application, which may include a heap allocated for the application for storing data during the running of the application and a stack allocated for the thread for storing parameters, local variables, etc. of the functions performed by the thread.
However, in an operating environment, there is a scenario where a large amount of data needs to be transferred, for example, an application including a plurality of processes is used for at least one of image processing, audio/video encoding/decoding, or network communication, and a corresponding plurality of processes is used for at least one of image processing, audio/video encoding/decoding, or network communication, different processes may implement different functions, and the processes cooperatively perform data processing, so that a large amount of data transmission between the processes is required. For example, each process transmits independent results to the main process in the form of message communication, and the main process returns final results to realize the functions of image processing, audio/video encoding/decoding or network communication.
The shared memory is a mode of inter-process communication (Inter Process Communication, IPC) and allows multiple processes to share the same memory area, so that the multiple processes can access the same shared memory block to access the same piece of data, sharing and transferring the data are realized, and communication overhead between different processes is saved. However, the programming language (e.g., node. Js) in the operating environment is an upper layer application language, which has low controllability on hardware and lacks the capability of directly operating the system memory, so that the built operating environment cannot realize memory sharing, and data transmission is performed between each process in a form of message communication, which is not beneficial to improving application performance. For example, a child process transfers data to a parent process after serializing, the parent process performs deserialization, there is a large overhead, and data that cannot be serialized cannot realize inter-process communication.
In the embodiment of the application, in the running environment based on the first programming language, the executable file based on the second programming language can be loaded through the programming interface, and the memory sharing is realized by the codes indicated by the executable file based on the second programming language, so that the memory sharing can be realized in the running environment of the first programming language, the communication expenditure among different processes is saved, and the application performance is improved. The code is written more naturally in a multi-process architecture in an operation environment based on the first programming language, data are not required to be transmitted mutually through process communication, and the convenience of code writing is improved as if all codes are operated in the same memory space on code writing.
The memory sharing can be realized by the executable file based on the second programming language, the second programming language is a lower programming language than the first programming language, the controllability of the second programming language to hardware is higher, so that the overall application function and the controllability of the second programming language to hardware can be considered by combining the first programming language and the second programming language, and the executable file can be obtained by compiling the program based on the second programming language by the programming interface, so that the executable file can be executed in the running environment based on the first programming Yuan.
For example, the first programming language may be node.js, the second programming language may be Rust, rust is a system level programming language developed by Mozilla corporation, and its design goal is to provide a secure, concurrent, efficient programming language, the programming interface may be an application editing interface (Application Programming Interface, API), and in particular may be an N-API (node.js API), which is a set of APIs for writing node.js c++ extensions, that provides a stable, cross-version programming interface such that c++ extensions can be run on different versions of node.js without recompilation, and that is easier to develop, maintain, and distribute. Thus, the operation of memory sharing among different processes can be realized through Rust language programming, and Rust language codes are compiled into executable files which can be called in a node.js environment by means of N-API, so that the capacity of sharing the same memory under the code architecture of multiple processes can be realized in the node.js environment.
S102, determining a corresponding shared memory space for the target memory identifier through the executable file.
In the embodiment of the application, the corresponding shared memory space can be determined for the target memory identifier through the executable file, the target memory identifier is used for uniquely indicating the shared memory space, and the shared memory space can be accessed by a plurality of processes in the running environment, so that data sharing among the plurality of processes is realized. The executable file is compiled from a second programming language based program, such as a Rust program.
The memory identifier may be expressed as a mem_id, where the memory identifier may include one or more memory identifiers used to indicate different shared memory spaces, and after the memory identifier is input with a value, the value is used as a target memory identifier, for example, mem_id is a memory.
Before determining the corresponding shared memory space for the target memory identifier, whether the target memory identifier exists or not may be determined, if yes, the shared memory space corresponding to the existing target memory identifier may be utilized, and when the shared memory space is utilized, memory data in the shared memory space will be covered by new memory data, or the corresponding shared memory space is redetermined for the target memory identifier. The shared memory space corresponding to the target memory identifier can be obtained as the shared memory space determined for the target memory identifier, or the corresponding shared memory space is updated for the target memory identifier after the shared memory space is reallocated for the target memory identifier. If the target memory identifier does not exist, a corresponding shared memory space can be determined for the target memory identifier. Therefore, the shared memory space can be effectively managed, and the space utilization rate is improved.
The method for determining the corresponding shared memory space for the target memory identifier may specifically be to create (create) an initial shared memory space, determine the shared memory space corresponding to the target memory identifier from the initial shared memory space, and allocate the corresponding shared memory space for the target memory identifier from the created initial shared memory space. Alternatively, a corresponding shared memory space may be created for the target memory identification. The determination mode of the shared memory space can be determined according to actual conditions, and the utilization rate of the memory space is improved.
The creation of the shared memory space or the initial shared memory space can be realized by a shared memory (SHmem) module in the Rust ecology, and the created shared memory space or the shared memory area in which the initial shared memory space is empty can be used for storing the data to be shared. Referring to fig. 3, a schematic process diagram of creating a shared memory space by a Rust program in this embodiment of the present application is shown, where when the shared memory space is created, a target memory identifier (mem_id) corresponding to the shared memory space, a size (size) of the shared memory space, and the like may be defined.
In the process of determining the corresponding shared memory space for the target memory identifier, a file corresponding to the target memory identifier may be created in the storage space, where the location of the file is used as the shared memory space corresponding to the target memory identifier, for example, the file corresponding to the target memory identifier may be used as a file name, for example, when the mem_id is memory.
S103, copying the data to be shared in the memory of the operating environment to the shared memory space.
After determining the shared memory space for the target memory identifier, the data to be shared may be copied (copy) into the shared memory space, where the copying of the data to be shared is implemented by an executable file. The data to be shared can be defined by a developer or according to a preset rule, so that the data to be shared in the shared memory space can be accessed by a plurality of processes, and memory sharing and data sharing among different processes are realized.
The shared memory space can store one data to be shared, can store a plurality of data to be shared, or can store the data to be shared corresponding to the target memory identifier into the shared memory space corresponding to the target memory identifier according to the association relation between the target memory identifier and the data to be shared. Because the shared memory space is used for being accessed by a plurality of processes in the running environment, the processes can share the data by accessing the same data in the shared memory space, so that the data transmission efficiency among the processes is improved, and the application performance is improved.
Referring to fig. 4, a flow chart of another memory sharing method in this embodiment of the present application is shown, where data to be shared may be stored in a memory of an operating environment, the data to be shared in the memory of the operating environment is copied to a shared memory space, and may specifically be S1031, a byte start address of the data to be shared in a stack of the memory of the operating environment and a byte length of the data to be shared are obtained, and S1032 copies the data to be shared to the shared memory space according to the byte start address and the byte length, so that the data to be shared in a non-shared stack may be copied to the sharable shared memory space, thereby realizing sharing of the data to be shared among multiple processes.
In actual operation, when the running environment is a node. Js environment, the data types of the data to be shared may include a basic type and a reference type. The same shared memory space can store data with the same data type, and can also store data with different data types.
The basic types include a number type and a character string type, and the data to be shared of the basic types is usually stored in a stack in the memory, so that the data to be shared of the basic types can be copied into the shared memory space in the manner described above. In the process of copying the data to be shared into the shared memory space, S1032 may specifically copy each bit in the data to be shared into the shared memory space in sequence by using the string pointer in the stack and the string pointer in the shared memory space according to the byte starting address and the byte length, specifically copy the character pointed by the string pointer in the stack into the memory location pointed by the string pointer in the shared memory space by using the memory copying capability provided by the Rust programming language, where the copied data to be shared exists in binary form.
Referring to fig. 5, a schematic diagram of a byte start address obtaining manner by a Rust program in the embodiment of the present application is shown, where basic type data may be converted into a target format, so as to obtain a byte start address of data to be shared in a stack, where the target format may be a uint8 (u 8) format. Referring to fig. 6, a schematic diagram of a process of data copying by a Rust program in the embodiment of the present application is shown, where a string pointer in a stack may be denoted as js string pointer, a string pointer in a shared memory space may be denoted as ptr string pointer, and in the process of data copying, a character pointed by the js string pointer may be copied to a shared memory location pointed by ptr.
The reference type may include a function type and an object type, the data to be shared of the object type may include a plurality of attributes, the data to be shared of the data type is usually stored in a heap in the memory, and is difficult to copy directly from the heap to the shared memory space, so that the data to be shared may be copied from the heap to the stack and then copied from the stack to the shared memory space, where the stack storing the data to be shared may be denoted as an intermediate storage space. The byte length of the data to be shared and its byte start address in the stack may be obtained before copying the data to be shared from the stack to the shared memory space.
Specifically, referring to fig. 7, a flow chart of another memory sharing method in this embodiment of the present application is shown, S1031 may be specifically that S1031A determines a byte length of data to be shared in a heap in a memory of an operating environment, S1031B allocates an intermediate storage space for the data to be shared in the heap in the memory of the operating environment according to the byte length, and obtains a string pointer of the intermediate storage space, S1031C writes the data to be shared into the intermediate storage space, S1031D determines a byte start address of the data to be shared in the intermediate storage space by using the string pointer of the intermediate storage space. The byte starting address of the data to be shared in the intermediate storage space is the byte starting address of the data to be shared in the stack of the memory of the operating environment, and then the data to be shared is copied to the shared memory space according to the byte starting address and the byte length. The intermediate storage space distributed according to the byte length can adapt to the size of the data to be shared, and the utilization efficiency of the storage space is improved. The byte starting address can be acquired in an auxiliary mode through the character string pointer of the intermediate storage space, and copying of data to be shared is assisted, so that sharing of the data to be shared, the data type of which is a reference type, is achieved.
Therefore, the data to be shared with the data type as the reference type can be stored in the shared memory space, the inter-process sharing of the data with the reference type is realized, the limitation that the data which can be serialized can only be transmitted through a message communication mode among processes in the traditional scheme is overcome, the data with the reference type which can not be serialized can be shared among all processes through the shared memory mode, and a child process can directly access any data in the memory of a parent process, so that services supported by the data with the reference type in the parent process can be accessed, and the limitation that the data transmission among the processes can be realized only through serialization is overcome.
Since the data type of the data to be shared may include a plurality of attributes when the data type of the data to be shared is a reference type, the byte length of the data to be shared in the heap in the memory of the operating environment may be determined according to the byte length of each attribute value of the data to be shared in the heap in the memory of the operating environment, for example, the byte length of the data to be shared may be the sum of the byte lengths of each attribute value. When the data type of the data to be shared is an object type, which can be expressed as jsObject, the actual byte length of the data to be shared in the heap can be dynamically acquired through a layout interface (layout api) of Rust.
In the process of copying the data to be shared into the shared memory space, S1032 may specifically copy each bit in the data to be shared into the shared memory space in turn by using the string pointer in the stack (i.e. the intermediate memory space) and the string pointer in the shared memory space according to the byte start address and the byte length, specifically copy the character pointed by the string pointer in the stack into the memory location pointed by the string pointer in the shared memory space by using the memory copying capability provided by the Rust programming language, where the copied data to be shared exists in binary form.
Referring to fig. 8, a schematic process of obtaining the byte length of the data to be shared by the Rust program in the embodiment of the present application is shown, where the actual byte length of the jsObject may be obtained by the layout method of the Rust program. Referring to fig. 9, a schematic process diagram of obtaining a byte start address of data to be shared in a stack by a Rust program in this embodiment of the present application is shown, specifically, an intermediate storage space may be allocated for the data to be shared, a string pointer of the intermediate storage space may be obtained, after the data to be shared is copied into the intermediate storage space, the byte start address of the data to be shared in the stack is obtained by means of the string pointer, so as to copy the data to be shared according to the byte start address and the byte length. Referring to fig. 10, another process diagram of data copying by the Rust program in this embodiment of the present application is shown, where a string pointer in the intermediate storage space may be denoted as a js string pointer, a string pointer in the shared memory space may be denoted as a ptr string pointer, and in the process of data copying, a character pointed by the js string pointer may be copied to the shared memory location pointed by ptr.
S104, storing the target memory identification and the memory area information of the shared memory space into the global variable.
In the embodiment of the present application, the target memory identifier and the memory area information of the shared memory space may also be stored in the global variable, and the storage of the target memory identifier and the memory area information of the shared memory space may be implemented by using an executable file, so that even if the executable file is executed, the target memory identifier and the memory area information of the shared memory space are also reserved, the shared memory space is not released by the system, and the data to be shared in the shared memory space is not deleted, so that access of multiple processes to the shared memory space is not affected even if the executable file is executed. Of course, the target memory identifier and the memory area information of the shared memory space may also be stored in the global variable after the shared memory space is created, so as to reserve the shared memory space for subsequent use.
Specifically, a global variable in the Rust memory can be created in advance for storing the memory area information, the type of the global variable can be a hash table (HashMap), the key (key) is a string type, the key is a memory identifier, the value is the memory area information of the shared memory space corresponding to the memory identifier, key value pairs between the target memory identifier and the memory area information of the shared memory space can be stored through the global variable, and each key value pair is used for maintaining a piece of shared memory space. Referring to fig. 11, a process diagram of creating a global variable by a Rust program in an embodiment of the present application is shown, where the global variable is initialized for subsequent use when the global variable is created. Referring to fig. 12, a process diagram of storing memory area information by a Rust program in an embodiment of the present application is shown, where a target memory identifier and memory area information of a shared memory space are inserted (inserted) into a global variable.
In this embodiment of the present invention, data stored in a shared memory space is stored in a binary form, so after data to be read in the shared memory space is acquired, format reduction may be performed on the data to be read to obtain data to be processed of an original data type, specifically, if the original data type of the data to be read is a reference type, format reduction may be performed on the data to be read to obtain data to be processed having an application type, and if the original data type of the data to be read is a basic type, format reduction may be performed on the data to be read to obtain data to be processed having a basic type. The format restoration of the data to be read may be achieved by an executable file. Referring to FIG. 13, a schematic diagram of a format reduction process by a Rust program in an embodiment of the present application is shown, where the data to be read may be reduced to the data to be processed in the character string type by str:from_utf8.
In this embodiment of the present application, the target memory information in the global variable may also be deleted by executing the file, where the target memory information includes a to-be-deleted identifier in the target memory identifier and memory area information of the shared memory space corresponding to the to-be-deleted identifier, so as to release the shared memory space corresponding to the to-be-deleted identifier, and implement control over the shared memory space. Referring to fig. 14, a schematic process diagram of a memory release by a Rust program in an embodiment of the present application is shown, where Rust provides a clear method for deleting a to-be-deleted identifier and memory area information of a shared memory space corresponding to the to-be-deleted identifier, so that the shared memory space is released, and stored data is deleted.
