Description

A subsystem implementation method and computing device

technical field

The present invention relates to the technical field of operating systems, and in particular, to a method for implementing a subsystem and a computing device.

Background technique

With the rapid development of processor technology, 64-word processors have become the mainstream, and have driven the rapid development of supporting 64-bit operating systems. At present, all mainstream operating systems support 64-bit, and more and more operating system distributions no longer release 32-bit images, and mainstream application software is gradually developing 64-bit.

Based on practical needs, some 32-bit applications are still reserved, and current mainstream operating system (such as Linux) distributions still retain the ability to support 32-bit applications. However, the maintenance cost of a large 32-bit application is already greater than the maintenance cost of the application itself. In real development, the maintenance of 32-bit applications is often untimely or incomplete, resulting in serious consequences such as dependency destruction, and also affects the normal use of 64-bit applications.

As 32-bit applications are about to withdraw from the mainstream market, it is necessary to consider managing 32-bit applications separately to improve the stability of the entire system environment. In view of the problem of mixed use of 32-bit programs and 64-bit programs, an isolated environment is required to run 32-bit applications.

In the prior art, there are two solutions for running 32-bit applications in an isolated environment implemented on Linux: chroot and container. chroot is a system call provided by the Linux kernel, through which the root directory of the process can be changed to achieve the purpose of isolating the environment. To use chroot to run 32-bit applications, you also need to prepare a rootfs. By changing the root directory of the process to the path where rootfs is located, chroot can complete the running of 32-bit applications with the help of basic settings such as ld provided in rootfs. However, the chroot environment cannot easily interact with the host (the main operating system). For example, GUI programs running in the chroot environment are cumbersome and require various settings.

Linux Container is an operating system-level virtualization method, which can not only achieve environment isolation, but also control the resource permissions of processes. Multiple isolated Linux systems can be run on a single Linux kernel through a container. Taking Docker as an example, Docker can easily manage OCI-compliant images and provide runtime support and management. Run a 32-bit Linux OCI (open container initiative) image through Docker, install the required dependencies, and run a 32-bit application inside the container.

Although both chroot and container can provide a runtime isolation environment to support 32-bit applications running in an isolated environment on 64-bit operating systems. However, for consumer users, the use of chroot and container is too cumbersome, and users need to perform complex configurations like developers in order to use the network, disks, monitors, etc. normally in an isolated environment. Moreover, these operations need to be performed on the command line terminal.

Therefore, a subsystem implementation method is required to solve the problems existing in the above solutions.

In this embodiment, an operating environment for running 32-bit applications on a 64-bit operating system can be implemented based on the subsystem.

FIG. 3 shows a flowchart of a method 300 for implementing a subsystem according to an embodiment of the present invention. FIG. 4 shows a sequence diagram of a subsystem implementing method 300 according to an embodiment of the present invention. The method 300 is adapted to be executed in an operating system of a computing device (the aforementioned computing device 100).

It should be noted that, in the specific embodiment, the present invention only takes the Linux operating system as an example to specifically describe the subsystem implementation method 300 . However, it should be understood that the subsystem implementation method 300 of the present invention is not limited to the specific type of the operating system that executes the method, and those skilled in the art can understand that the method can also be used in other types of operating systems, such as Windows operating systems. can be realized without the need for creative labor. Any type of operating system that can run the second-digit application program on the first-digit operating system through the method of the present invention falls within the protection scope of the present invention.

As shown in Figures 3 and 4, the method 300 begins at step S310.

In step S310, a user's operation request for the second-digit application program 132 is received.

Here, the operating system 150 provides an interface to the user space, so that the user space can call the interface provided by the operating system 150 to communicate with the operating system 150, and specifically can interact with the system basic tools in the operating system 150. The system basic tools include, for example, package management tools, various service programs, compilation tool chains, etc., and the present invention is not limited to these system tools.

For example, when the user needs to install or uninstall the second-digit application program 132 in the subsystem on the operating system 150, the user can call the interface of the package management tool provided by the operating system 150 to request the second-digit application program 132 to be installed or uninstalled. Install operation, uninstall operation, or start operation. Thus, the operating system 150 may receive a request for installing, uninstalling or starting the second-digit application program 132 sent by the user invoking the interface of the package management tool.

When a user (developer) needs to develop the second-digit application program 132 , the user can call the interface of the compilation tool chain provided by the operating system 150 to request the second-digit application program 132 to be compiled. Thus, the operating system 150 can receive a request for compiling the second-digit application program 132 sent by the user invoking the interface of the compiling tool chain.

In this way, in the embodiment of the present invention, in step S310, the user's operation request to the second-digit application program 132 may specifically include: various interfaces provided by the user through the operating system 150, and the second-digit application program 132 sent by the user. Requests for installation, uninstallation, startup, and compilation.

Subsequently, in step S320, based on the user's operation request for the second-digit application program 132, a corresponding operation command is generated, and the generated operation command is sent to the subsystem manager 130 running in the operating system 150.

It should be noted that, according to the embodiment of the present invention, the user can request the installation operation, uninstallation operation, startup operation, and compilation operation of the second-digit application program 132 through various interfaces provided by the operating system 150, and is not limited to These kinds of operations. Correspondingly, the operation command generated by the operating system 150 based on the operation request may include one or more of an installation operation command, an uninstallation operation command, a startup operation command, and a compilation operation command for the second-digit application program 132, and no Limited to the above operation commands.

Finally, in step S330, the subsystem manager 130 sends the operation command to the target subsystem corresponding to the second-digit application program, so that the target subsystem executes the operation command for the second-digit application program 132.

It should be noted that, according to the method 300 of the present invention, when the user operates the second-digit application program, he still calls the interface provided by the operating system to realize, and the operating system generates the corresponding operation command according to the user's operation, The operation command is forwarded to the subsystem manager, and the operation command is sent to the subsystem where the second-digit application program is located (that is, the target subsystem corresponding to the second-digit application program) through the subsystem manager for execution. In this way, when the user operates the second-digit application program, whether it is an installation operation, an uninstall operation, a startup operation, or a compilation operation, it is the same as operating the first-digit application program on the operating system, and the user will not feel the subsystem. There is no difference in use and operation between the second-digit application and the first-digit application, so the user does not need to additionally learn how to interact with the second-digit application.

It can be seen that, according to the method 300 of the present invention, the user can operate the second-digit application program on the first-digit operating system without perception, and the interaction mode is more friendly, which greatly reduces the use of the first-digit operating system by the user. Learning costs for second-digit applications. Moreover, based on the operating environment isolated from the operating system provided by the subsystem, the operation of each first-digit application program on the operating system will not be affected when the subsystem is abnormal, which is beneficial to improve the stability of the system operation.

According to an embodiment of the present invention, the operating system 150 may define various operation requests of the user as operation commands in a metadata format, and the metadata format is a data format in which the operating system 150 interacts with the subsystem, and then the metadata format may be The operation command is sent to the subsystem manager 130 . Further, the operating system 150 may send operation commands to the subsystems by means of message subscription and publication. Specifically, the operating system 150 may encapsulate the operation command into an operation command message in a metadata format, and send the operation command message to the subsystem manager 130 through a message queue. Here, the subsystem manager 130 may subscribe the operation command message to the operating system 150. After the operating system 150 encapsulates the operation command into the operation command message in the metadata format, the operation command message is added to the message queue, and then the subsystem manages The server 130 can obtain the operation command message from the message queue.

According to an embodiment of the present invention, each subsystem can run one type of second-digit application program, and different second-digit application programs run in different subsystems. Here, the second-digit applications with the same package name are the same second-digit applications. When sending the operation command to the subsystem corresponding to the second-digit application program, the subsystem manager 130 first determines the second-digit application program 132 corresponding to the operation command, and determines the target sub-system corresponding to the second-digit application program 132. system. Subsequently, an operation command is sent to the target subsystem.

In one embodiment, before sending the operation command to the subsystem corresponding to the second-digit application program, the subsystem manager 130 parses the operation command (operation command message) to determine whether the operation command needs to be executed by the subsystem . If it is determined that the operation command needs to be executed by the subsystem, the operation command is sent to the target subsystem corresponding to the second-digit application program, so that the operation command is executed in the target subsystem.

In addition, if the operation command does not need to be executed by the subsystem, the operation command is sent to the operating system 150 so that the operation command is executed in the operating system 150 .

In one embodiment, before step S310 is performed, the subsystem manager 130 may obtain a system image corresponding to each subsystem, and decompress the system image to a predetermined installation directory, so as to install the subsystem in the computing device. Thereafter, the second digit application 132 may be installed in each subsystem. In an implementation manner, the second digit is 32 bits, and correspondingly, the subsystem manager 130 is a 32-bit subsystem manager 130 .

In one implementation, considering the portability of the subsystem, an image that conforms to the OCI specification can be built as the subsystem image to realize the migration of the subsystem, and the namespace, cgroup, capability, etc. provided by the Linux kernel can be used. Technology to achieve environment isolation, resource control and authority management of subsystems. The subsystem manager 130 realizes the subsystem operating environment by acquiring the subsystem image and decompressing the system image file to a predetermined installation directory. Furthermore, the second-digit application program 132 may be installed in the subsystem directory, so as to realize the running of the second-digit application program 132 in the subsystem on the operating system 150 .

In one embodiment, when the operation command is an installation operation command for the second-digit application program 132, the subsystem manager 130 determines that the user is the second-digit number to be installed according to the installation operation command by parsing the installation operation command The target subsystem configured by the application 132 . Further, the installation operation command is sent to the target subsystem, so that the target subsystem executes the installation operation command. After the target subsystem executes the installation operation command, the second-digit application program 132 can be installed in the target subsystem. . In addition, the user can also configure the installation path in the target subsystem for the second-digit application program 132 to be installed. In this way, the target subsystem can implement the installation operation command to install the second-digit application program 132 in the target subsystem. under the installation path of the system.

In addition, the subsystem manager 130 may record the corresponding relationship between the second-digit application 132 and the subsystem in the system log. In this way, when the subsystem manager 130 receives an operation command for the second-digit application program 132, it can determine the target subsystem corresponding to the second-digit application program 132 based on the system log.

It should be noted that the subsystem manager 130 includes a user process (Client) and a service process (Daemon), wherein the user process Client of the subsystem manager 130 can provide a management interface to the user, such as a GUI (Graphical User Interface, graphical user interface). ) or CLI (command-line interface). The service process Daemon of the subsystem manager 130 can monitor the operation requests sent by the user calling various interfaces of the operating system 150 .

In one implementation, the user can configure the target subsystem to be installed for the second-digit application 132 through the user process of the subsystem manager 130, and can configure the second-digit application 132 in the target subsystem so that the second digit application 132 is installed in the corresponding location of the target subsystem based on the installation path.

Daemon can obtain the target subsystem configured by the client for the second-digit application 132 and the installation path in the target subsystem, and obtain the package name of the second-digit application 132 and the corresponding target subsystem, target The installation paths in the subsystem are associated in the system log. In this way, when the subsystem manager 130 receives an operation command for the second-digit application program 132, it can determine the target subsystem corresponding to the second-digit application program 132 based on the system log, and send the operation command to the target sub-system executed in the system.

In an implementation manner, the subsystem manager provides a configuration file that supports formats such as ymal, and the subsystem can be configured based on the configuration file, so as to perform personalized settings for the installation location of the second-digit application 132 .

In one embodiment, when the operation command received by the subsystem manager 130 is a start operation command for the second-digit application program 132, the subsystem manager 130 determines the second-digit application program corresponding to the start-up operation command by determining 132. Determine the target subsystem corresponding to the second-digit application program 132 based on the system log, and send the start-up operation command to the target subsystem, so that the target subsystem executes the start-up operation command, thereby realizing starting the second-digit number in the target subsystem. Number of applications 132.

In addition, in one embodiment, when the user (developer) needs to develop the second-digit application program 132, the user can call the interface of the compilation tool chain provided by the operating system 150 to develop the second-digit application program 132 Compile operation. The operating system 150, in response to the user's compilation operation request, generates a corresponding compilation operation command based on the user's compilation operation request, and sends the compilation operation command to the corresponding target subsystem, so as to pass the second-digit toolchain corresponding to the target subsystem. to execute the compile operation command, so as to implement the compile operation on the second-digit application program 132 in the target subsystem.

It should be noted that the normal operation of the second-digit application 132 in the subsystem depends on the support provided by the subsystem manager 130 . For example, the operating system 150 includes a user directory, and in one embodiment, the subsystem manager 130 may bind the user directory into the subsystem. In this way, the second-digit application 132 running in the subsystem can access the user directory, and the second-digit application 132 can create a shortcut in the same way that the first-digit application creates a shortcut.

In addition, the subsystem manager 130 may also map the user identification (UID) and group identification (GID) of the operating system 150 into the subsystem, so that the second-digit application 132 running in the subsystem is compatible with the running The first digit application 131 on the operating system maintains the same user identification (UID) and group identification (GID).

In one embodiment, when the second-digit application 132 registers the service in the subsystem, the subsystem manager 130 may generate a copy of the service for storage in response to the operation of the second-digit application registering the service in the subsystem , and register the service with the operating system 150, so as to ensure the normal operation of the service of the second digit application 132.

In one embodiment, in order to ensure the normal operation of the GUI application, the subsystem manager 130 may save the DISPLAY variable of the operating system 150 as a copy for each subsystem to use. For tools such as xdgopen, the subsystem manager 130 will Intercept the operation of the subsystem. Specifically, when the subsystem manager detects that the subsystem needs to use the xdgopen tool to operate, it forwards the corresponding operation command to the operating system for execution.

According to the subsystem implementation method 300 of the present invention, by deploying one or more subsystems on the operating system of the first digit, the subsystem can provide the application program of the second digit with an operating environment isolated from the operating system, thereby realizing A runtime environment for running second-digit applications on the first-digit operating system. When the user operates the second-digit application program, he still calls the interface provided by the operating system, and the operating system generates the corresponding operation command according to the user's operation, and forwards the operation command to the subsystem manager. The manager sends the operation command to the subsystem where the second-digit application program is located for execution. In this way, according to the implementation scheme of the present invention, the user can operate the second-digit application program on the first-digit operating system without perception, and the interaction mode is more friendly, which greatly reduces the use of the first-digit operating system by the user. Learning costs for second-digit applications. Moreover, based on the isolation environment provided by the subsystem, when the subsystem is abnormal, it will not affect the operation of each first-digit application program on the operating system, thereby facilitating maintenance and improving the stability of the system operation.
