Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
At present, in the process of using application software, a user may start the same application software for multiple times, the essence of starting the application software each time is to create one process, an operating system may respond to a request of the user to create the application software for multiple times, multiple processes are often occupied by large memory resources, and the continuous operation of multiple processes makes the memory resource overhead of equipment too large, which is prone to the occurrence of situations such as equipment jamming and application software jamming, and thus, user experience is seriously affected. In addition, the sharing of data among the processes is difficult to realize, so that the communication among application windows of application software started by different processes is difficult to realize.
When the bus provided by the operating system has the service corresponding to the application software, the application window object of the registered application software is acquired from the bus according to the service, the function of the application window object is called to create the application window of the application software, only one process continuously runs in the process of starting the same application software for multiple times, the application windows of the application software are all created in the process, and other processes are terminated after responding to a request of a user for creating the application windows.
Specifically, in response to a request from a user to create an application window of application software, a process is created, whether or not a service corresponding to the application software exists is inquired in a bus provided by an operating system, if no service exists, the process is a continuously running process, then the operating system creates an application window object for the application software, and registers the service and the created application window object with the bus, if the service exists, the created process is other processes, the operating system acquires the application window object of the registered application software from the bus according to the service, and calls the function of the application window object to realize the creation of the application window of the application software in the resident process and to terminate the other processes, therefore, resources occupied by other processes are released, the time occupied by the resources is reduced, the resource utilization rate is improved, and application windows of all application software are created in the resident processes.
That is to say, when a user requests to open the same application software for multiple times, the multiple processes in the prior art continuously operate, and the process is converted into the process continuously operating, that is, the multiple processes in the prior art continuously occupy the memory resource, and the process is converted into the process continuously occupying the memory resource, so that the occupation of the resource is greatly reduced, the resource utilization rate is improved, the situations of equipment blockage and application software blockage can be effectively relieved, and the user experience is improved.

According to one embodiment, the temporary process described in the following of the present disclosure is a process that is terminated in response to a request from a user to create an application window of application software, that is, the temporary process is a process that is terminated after a program is run. The resident process described in the following content of the scheme is a continuously running process, application windows of application software to be created by the temporary process are all created in the resident process, and the resident process is terminated only when all the created application windows are closed, so that a plurality of processes occupy resources and only one process occupies the resources. Wherein the temporary process and a resident process communicate through a message Bus system D-Bus.
It should be noted that the application software corresponds to a service, and a service includes a plurality of objects, which correspond to a plurality of functions.
When the service corresponding to the application software does not register the service with the bus, the operating system 120 creates a process in response to a request from a user to create an application window of the application software, where the created process is a resident process, registers the service corresponding to the application software with the bus in the resident process, and registers an object of the application window of the application software created in the resident process with the bus. When the service corresponding to the application software registers the service with the bus, the operating system 120 responds to the request of the user for creating the application window of the application software, creates a process, the created process is a temporary process, obtains the application window object of the registered application software from the bus in the temporary process according to the service registered by the resident process with the bus, calls the function of the application window object, realizes the creation of the application window of the application software in the resident process, and terminates the temporary process. Wherein, the temporary process and the resident process communicate through a message Bus system D-Bus.
The service, as described herein, is an application type, the service runs in the background, and the service may typically provide some functionality locally to the user or over a network to support other applications. Wherein the application is part of the application software.
As shown in fig. 2, the execution method 200 of the application software starts in step S210. In step S210, a process is created in response to a request from a user to create an application window of application software. The application window is an interface which pops up when the application software is started.
Subsequently, in step S220, it is queried in the bus provided by the operating system 120 whether a service corresponding to the application software exists.
Thereafter, in step S230, if there is no service, an application window object of the application software is created, and the service and the created application window object are registered with the bus. An application window object here is an application window instance.
FIG. 3 is a flow diagram of a method 300 for an operating system 120 to register services and created application window objects of application software with a bus in a resident process. When there is no service in the bus provided by the operating system 120, the flow shown in fig. 3 is executed. As shown in FIG. 3, a method 300 for the operating system 120 to register a service and an application window object for a created application software with the bus in a resident process begins at step S310.
In step S310, a bus of a type corresponding to the service is selected. Since the bus is mainly divided into session bus (session bus) and system bus (system bus), and the communication between a resident process and a temporary process is realized through the message bus system in this embodiment, in one embodiment, the selected bus type is the session bus. The dialog bus may be: SPI, I2C, USB, RS232, and the like.
After the bus type is selected, the named service is registered with the selected bus for service naming in step S320. In an embodiment of the present invention, the service may be named in a self-defined manner, and the subsequent temporary process may also obtain the service from the bus by using the self-defined service name, which is not particularly limited in the present invention.
Registering the named service with the selected bus specifically includes: the operating system 120 calls the sessionBus () function of the bus to obtain the bus object, defines the service name, and calls the registerService () function of the bus object to register the named service with the bus after defining the service name.
Subsequently, in step S330, an application window object of the application software is created in the process, named for the application window object of the application software.
The application window object may be named in a self-defined manner, or may be named in another manner, as long as the temporary process uses the same object name as that used in registration when acquiring the application window object from the bus, which is not limited in the present invention.
After the application window object of the application software is created in the resident process and the service is successfully registered with the bus, the application window object of the named application software is registered with the bus in association with the registered service in step S340. Specifically, firstly, the service registered with the bus is obtained, and the named application window object is related and bound to the adapter according to the registered service, so that the subsequent temporary process obtains the application window object of the application software registered with the bus and calls the function of the application window object of the application software registered with the bus. Then, the bus registerebject () function is called, and the application window object of the application software is registered with the bus by the registerebject () function.
After the resident process registers the service and the application window object of the application software with the bus, in step S240, if the service exists, the resident process acquires the application window object of the registered application software from the bus according to the service, calls a function of the application window object to create an application window of the application software, and terminates the process.
Specifically, the method comprises the following steps: based on the service name and the application window object name defined in the steps S320 and S330 and the bus type selected in the step S310, the application window object of the application software is acquired from the bus, the createspubwindow () function of the application window object of the application software is called through the adapter, and based on the createspubwindow () function of the called application window object, a function return value is obtained, after the function return value is returned, the creation of the application window of the application software in the resident process is realized, and the temporary process is terminated.
The function return value is used for judging the time for terminating the temporary process, and the temporary process can be terminated as long as the function return value is returned no matter whether the function return value is correct or not, so that the temporary process is terminated after the temporary process responds to a request of a user for creating an application window of application software, memory resources occupied by the temporary process are released in time, and the resource utilization rate of the computing equipment 100 is improved. For example, if the return value of the object function is wrong, the type of the error is returned, and corresponding processing is performed according to requirements, and if the return value of the object function is wrong, the application window which is created by the user request is not created, and the temporary process is terminated. If the return value of the object function is effective, processing meeting the requirement is carried out according to the content of the return value, if the return value of the object function is effective, an application window which is created by a user request is created, and the temporary process is terminated.
The temporary process realizes the creation of the application window of the new application software in the resident process by calling the createsubsWindow () function of the application window object. At this time, a plurality of application windows may exist in the resident process, and the plurality of application windows may communicate with each other, that is, data exchange between the plurality of application windows is enabled.
It should be noted that the application window created for the first time in the resident process is the same as the application window created in the resident process by the object function of the temporary process access application window, and there is no difference.
According to the steps, when the bus provided by the operating system has the service corresponding to the application software, the application window object of the registered application software is acquired from the bus according to the service, the function of the application window object is called to create the application window of the application software, only one process (namely a resident process) continuously runs in the process of starting the same application software for many times, the application window of the application software is created in the process, and other processes (namely temporary processes) are terminated after responding to a request of creating the application window by a user. Therefore, the invention can realize that only one process continuously runs when a user requests to open the same application software for multiple times, namely, the memory resources are continuously occupied by a plurality of processes in the prior art, and the memory resources are converted into the memory resources continuously occupied by only one process, thereby greatly reducing the occupation of the resources, improving the utilization rate of the resources, effectively relieving the conditions of equipment blockage and application software blockage, and improving the user experience.
After creating the application windows of the application software in the resident process, the operating system 120 may record the number of the application windows of the created application software, may record the number of the created application windows in a reference counting manner, and may also record the number of the created application windows in other counting manners, which is not limited in the present invention.
When the temporary process responds to the request of the user for creating the application window by calling the function of the application window object of the application software registered by the resident process to the bus, the resident process creates an application window of the application software, and at the moment, the operating system adds 1 to the recorded number of the application windows of the created application software. If the operating system 120 monitors an event that the user closes the application window, in response to the event that the user closes the application window of the application software, the application window of the corresponding application software is closed in the resident process, and at this time, the number of the previously recorded application windows of the created application software is reduced by 1. It should be noted that, among the application windows created in the resident process, closing one or more application windows does not affect other application windows that are not closed.
In addition, in order to ensure that the resources occupied by the process are released in time, the resident system 120 may determine whether the application window creation number of the application software in the process is 0, if so, terminate the resident process, and timely recover the memory resources occupied by the resident process, and if not, then not terminate the resident process.
As can be seen from the above, in response to a request of a user to open the same application software for multiple times, multiple application windows are created in one resident process, and the application windows of the multiple application software in one resident process communicate with each other through a slot function mechanism, which is a signal function mechanism that the resident process registers an application window object of the application software with a bus, so that the communication between the application windows of the application software in the present invention is actually the communication between multiple threads under one process. That is, the data exchange between application windows of the application software in the present invention is the data exchange between threads.
Compared with the existing scheme, the method has the advantages that the application windows of the plurality of application software are created in response to the request of a user for opening the application software for a plurality of times, the essence of creating the application window of the application software for each time is to create one process, and after the application window of the application software is created for a plurality of times, a plurality of processes are created, so that the communication among the application windows of the application software is the communication among the processes, namely the data exchange among the processes. However, data exchange between processes is difficult to implement, and the data exchange between processes consumes a lot of memory resources.
However, in the invention, because a plurality of application windows of the application software are created in one resident process, the data exchange between the application windows of the application software is realized, and the data exchange between the threads is realized, so that the data exchange between the application windows of the application software is simple, the memory resources consumed by the data exchange between the application windows can be reduced, and the situations of equipment jam, application software jam and the like caused by overlarge expenditure of the memory resources of the equipment are effectively relieved.
Fig. 4 is a flowchart of a complete application software execution method 400 according to the present invention, and as shown in fig. 4, the application software execution method 400 starts at step S401.
In step S401, a process is created in response to a request from a user to create an application window of application software;
subsequently in step S402, it is queried in the bus provided by the operating system 120 whether a service corresponding to the application software in step S401 exists;
if the service does not exist, the process is a resident process, and a bus of a type corresponding to the service is selected in step S403;
subsequently, in step S404, for service naming, the named service is registered with the selected bus;
after the service is successfully registered with the bus in step S404, an application window object of the application software is created in the process and named for the application window object of the application software in step S405;
next in step S406, the application window object of the application software named in step S405 is registered with the bus in association with the registered service;
if the service exists, the process is a temporary process, in step S407, an application window object of the registered application software is acquired from the bus according to the service, and a function of the application window object is called to implement creation of an application window of the application software in the resident process, and the temporary process is terminated;
after creating the application windows of the application software in the resident process by step S407, recording the number of the application windows of the created application software in step S408, when the temporary process responds to the request of the user to create the application window by calling the function of the application window object of the application software which the resident process has registered with the bus, creating an application window of the application software in the resident process again, and similarly adding 1 to the number of the application windows of the recorded and created application software in step S408;
subsequently, in response to an event that the user closes the application window of the application software, in step S409, the application window of the corresponding application software is closed in the resident process;
next, in step S410, the number of application windows of the created application software recorded in step S408 is decremented by 1;
in step S411, it is determined whether the number of application windows created by the application software in the process is 0, and if not, the process returns to step S409, and if 0, the resident process is terminated in step S412.
Through the complete flow of fig. 4, when a user requests to open the same application software multiple times, the application window of the same application software is opened multiple times in one process. Fig. 5 is a diagram 500 illustrating the number of corresponding processes when the same application software is opened multiple times, in fig. 5, fig. 5b is a resident process, and fig. 5a, 5c, and 5d are three application windows created in the resident process. It can be known from the content shown in fig. 5 and the above-mentioned scheme that, when there is a service corresponding to the application software in the bus provided by the operating system, the application window object of the registered application software is obtained from the bus according to the service, and the function of the application window object is called to create the application window of the application software, so that only one process continuously runs in the process of starting the same application software for many times, that is, only one process continuously occupies resources, and therefore, the occupation and consumption of memory resources can be greatly reduced, and the situations of equipment blockage, application software blockage and the like can be effectively alleviated.
