Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In the following description, suffixes such as "module", "component", or "unit" for representing elements are used only for facilitating the description of the present invention, and have no specific meaning per se. Thus, "module," "component," or "unit" may be used in combination.
The terminal may be implemented in various forms. For example, the terminals described in the present invention may include mobile terminals such as cell phones, tablet computers, notebook computers, palm computers, personal digital assistants (Personal Digital Assistant, PDA), portable media players (Portable Media Player, PMP), and fixed terminals such as digital TV, desktop computers, and the like.
The following description will be given taking a mobile terminal as an example, and those skilled in the art will understand that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for a moving purpose.
Referring to fig. 1, fig. 1 is a multi-process processing method provided in an embodiment of the present invention, which is applied to a terminal, and includes the following steps S101 to S106:
s101, acquiring task information to be executed of a main process.
The task information to be executed in the embodiment of the application is panel window information needing to be operated by the main process, and the task information to be executed includes the number of tasks to be executed, namely the number of panel windows needing to be operated by the main process.
S102, judging whether the task information to be executed meets the set sub-process creation condition.
In this embodiment of the present application, the task information to be executed includes the number of tasks to be executed, and determining whether the task information to be executed meets a set sub-process creation condition includes: judging whether the number of the tasks to be executed is larger than a set threshold value of the tasks to be executed; and when the number of the tasks to be executed is larger than the set threshold value of the tasks to be executed, determining that the information of the tasks to be executed meets the set sub-process creation condition.
S103, when the task information to be executed meets the set sub-process creation conditions, creating at least one sub-process, wherein the at least one sub-process has a unique sub-process identifier; the at least one sub-process is one or more of a plurality of sub-processes.
When the main process is used for independently opening the panel window, a sub-process is newly established to load the panel window, if a plurality of panel windows need to be operated, each panel window which is independently opened from the main process is newly established to load the panel window, business logic and data of each sub-process are relatively independent, and the main process and the sub-process are only different in display panel window, so that the multi-process transformation cost is greatly reduced.
Meanwhile, when a sub-process is newly built, a sub-process identifier (i.e. an ID of the sub-process) of the sub-process is recorded, and the sub-process identifier is used for the communication between the main process and the corresponding sub-process. Only the main process needs to establish network connection with the server, other sub-processes send and receive communication data through the main process, the communication data can be synchronized at a network layer, and the following two conditions are included according to different types of the communication data:
in the first case, when the communication data sent by the server is push protocol data, because the push protocol data does not relate to request operation, and all the sub-processes need to receive the push protocol data in real time, the main process directly distributes the received push protocol data to all the sub-processes after receiving the push protocol data.
For example, the sub-process includes sub-process 1, sub-process 2 and sub-process 3, and the main process distributes the received push protocol data to sub-process 1, sub-process 2 and sub-process 3 in real time.
In the second case, when the communication data is request response protocol data, since the packet of the request response protocol data is generally associated with the request response protocol data, and other sub-processes do not have the request response protocol data of the sub-process initiating the request, the packet of the protocol data is sent to the corresponding sub-process only for processing after the main process receives the packet of the protocol data.
For example, the sub-process includes a sub-process 1, a sub-process 2, and a sub-process 3, and when the sub-process 1 requests K-wire data of a certain stock, the execution flow is: the subprocess 1 sets a unique request serial number x for the protocol data of the request K line data and sends the protocol data to the main process; after the main process receives the protocol data of the sub-process 1, the main process sends the protocol data to a server, generates a sequence number y of a network request, and records the corresponding relation between y and (the sub-process 1, the request sequence number x); when the main process receives the back packet of the server, the corresponding relation (the sub-process 1 and the request sequence number x) recorded before is obtained through the network request sequence number y of the back packet, and the back packet and the request sequence number x are sent to the sub-process 1; when the sub-process 1 receives the callback packet and the request sequence number x, the callback packet can be analyzed and the callback packet can be called back to the service layer for processing; in this process, the other sub-processes do not receive the above-mentioned return packet sent by the main process.
S104, the main process sends a starting request message to at least one sub-process, wherein the starting request message carries a main process identifier, a sub-process identifier and a sub-task to be executed corresponding to the at least one sub-process.
In this embodiment, before the main process sends the request message to the at least one sub-process, the method further includes: establishing a communication pipeline between the main process and at least one subprocess according to the main process identifier of the main process and the subprocess identifier of the at least one subprocess; and carrying out communication data distribution between the main process and at least one corresponding sub-process by utilizing each communication pipeline, wherein the communication data comprises byte stream data.
In the embodiment of the application, naming is performed on each established communication pipeline according to a preset naming rule. The preset naming rule is the naming of the corresponding communication pipeline between the main process and the sub-process generated according to the main process identification and each sub-process identification.
In the embodiment of the application, the communication data is encrypted by using the secret key; the public key of the secret key is used for generating first identification information for a main process, and the main process sends the public key to at least one sub-process through a shared memory; the public key and the set private key are used to generate a secret key using the MD5 message digest algorithm.
In an embodiment of the present application, the communication data includes public data and/or configuration data stored in a shared memory, and the method further includes: locking the shared memory by using the mutual exclusion lock; judging whether the main process and at least one subprocess simultaneously execute access operation to public data and/or configuration data; if yes, further judging whether the main process or at least one sub-process has a mutual exclusion lock; if yes, the main process or at least one sub-process is utilized to directly access the public data and/or the configuration data, and the mutual exclusion lock is released after the access operation is completed.
In the embodiment of the application, the shared memory allows multiple processes to access the same memory block, namely, the main process and the sub-process can read and write the common data and/or the configuration data at the same time, and in order to avoid access conflict, the application performs mutex locking processing aiming at read and write operation.
S105, the main process receives a starting response message sent by at least one sub-process and a connection establishment request.
After receiving the startup response message sent by the subprocess, the main process indicates that the subprocess opens the subprocess, at the moment, the panel window interface of the subprocess is temporarily hidden, the panel window interface can be displayed only by establishing connection between the subprocess and the main process, and after the subprocess opens, a connection establishment request is sent to the main process.
S106, the main process sends a response message corresponding to the connection establishment request to at least one sub-process according to the connection establishment request, so that the at least one sub-process loads the corresponding sub-task to be executed according to the received response message.
When the subprocess is opened, a subtask to be executed, which is sent to the subprocess, carries a panel window layout key which needs to be opened by the subprocess, the subprocess temporarily hides the panel window interface after being started, obtains the name of a communication pipeline which is used for distributing communication data with the main process through a main process identifier and a preset naming rule in a received starting request message, establishes the communication pipeline with the main process, names the communication pipeline according to the obtained name, sends a connection establishment request to the main process through the communication pipeline, sends initialization data which are acquired by the main process to the subprocess when the main process receives the connection establishment request sent by the subprocess, wherein the initialization data comprise but are not limited to account information and stock market information, considers that the connection establishment with the main process is successful after the subprocess receives the initialization data returned by the main process, opens a corresponding panel window according to the panel window layout key received during the starting, and displays the panel window interface.
According to the method and the device, performance optimization can be performed on scenes that a plurality of panel windows are opened on a plurality of screens by stock users, each subtask corresponds to one process, namely, each independent panel window corresponds to one process, the advantages of CPU multi-core can be fully utilized, meanwhile, occupation of other system resources such as memory and handles is shared, and performance of stock software is improved.
