Example 1
Fig. 1 is a flowchart of a task terminal preemption method provided in an embodiment of the present application, where the embodiment of the present application is applicable to a situation where an audio terminal is preempted after receiving a preemption task, where the method may be performed by a preemption device of the task terminal, where the preemption device of the task terminal may be implemented in hardware and/or software, and where the preemption device of the task terminal may be configured in an electronic device with data processing capabilities. As shown in fig. 1, the method includes:
S110, if a task preemption request is received, determining a preemption task and a target terminal which needs preemption of the preemption task according to the task preemption request; and the preemption task corresponds to at least one target terminal.
The task preemption request can be a request sent by other services or a notification; the task preemption request reflects that task preemption needs to be performed on the terminal, and the preemption task may be a task that preemption is performed on an existing task, and the preemption task may specifically be an audio preemption task, where the preemption task may include: preemption time, priority, preemption content, terminal information to be preempted, etc.
The target terminal may be any of the terminals that need to be preempted by the preemption task.
Specifically, after receiving the preemption task request through the corresponding interface, the request may include preemption task information, so that the preemption task may be read from the preemption task information, and a target terminal to be preempted by the preemption task.
Taking terminal 1 as an example, terminal 1 plays task a, when preemption task B is received, preemption task B needs to be played on terminal 1, and preemption task B has a higher priority than task a, where a subsequent preemption step can be performed. In the embodiment of the application, the task preemption process is performed in the electronic equipment, namely, after the preemption is successful, the absolute account book data comprising the preemption result is required to be placed in the database, and other services read the information in the database, so that the preemption process is performed on the terminal.
S120, determining a preemption result according to the preemption task and the priority of the preemption task which are being executed on the target terminal.
In the embodiment of the application, the memory is provided with the information of the task to be executed and the task being executed of each terminal, and the information of the executing terminal corresponding to each task, so that the information of a certain task and the information of a certain terminal can be directly used when being obtained later.
Specifically, after the target terminal is determined, checking the task which corresponds to the target terminal and is being executed, wherein the task is the preempted task, judging the preempted task and the priority of the preempted task, and further determining whether the preempting is successful or not, namely generating a preempting result.
Specifically, if the priority of the preempted task is higher than the priority of the preempted task, the target terminal should continue to execute the preempted task, and the preemption result in this case is a preemption failure. If the priority of the preempted task is lower than the priority of the preempted task, the preempted result can be determined as the preempted success.
Further, after the preemption result corresponding to the target terminal is obtained, traversing each terminal in the same way to obtain the preemption result of each terminal.
It should be noted that, if the target terminal is not in the audio mixing playing mode, that is, the target terminal can only execute one task (play one music) at the same time, the preemption result may be determined according to the priority of the preempted task and the preemption task being executed on the target terminal.
In the embodiment of the present application, optionally, in the case that the target terminal is a mixed audio playing, determining the preemption result according to the priority of the preempted task and the preempted task being executed on the target terminal includes: if the preempted task and the preempted task belong to the same audio channel, determining a preempted result according to the priority of the preempted task and the preempted task being executed on the target terminal; the method further comprises the steps of: if the preempted task and the preempted task do not belong to the same audio channel, determining that the preempted task and the preempted task occupy the corresponding audio channels in the target terminal respectively.
Note that, mixing refers to that one terminal performs a plurality of tasks simultaneously, for example, channel 1 performs a task, channel B performs a task, and so on (for example, one terminal plays a plurality of pieces of music simultaneously, respectively, foreground sound, background sound, and so on).
Specifically, for the situation of mixing, if the preempted task and the preempted task belong to the same audio channel, determining a preempted result according to the priority of the preempted task and the preempted task being executed on the target terminal. If the preempted task and the preempted task do not belong to the same audio channel, i.e. no task exists on the channel to be preempted by the preempted task, the preempted task and the preempted task can be determined to occupy the corresponding audio channels in the target terminal respectively.
S130, determining the execution terminal corresponding to the preemption task according to the preemption result of each terminal corresponding to the preemption task.
In the embodiment of the present application, optionally, determining an execution terminal corresponding to a preemption task according to preemption results of terminals corresponding to the preemption task, including: determining whether the preemption of the preemption task to the terminal is successful or not according to the preemption result; if the preemption task is successful in preempting the terminal, the terminal is determined to be an executing terminal corresponding to the preemption task.
For example, if the terminal corresponding to the preemption task is: terminal 2, terminal 3 and terminal 4; the preemption task needs to preempt the terminal, if the preemption results of the preemption task on the terminal 2 and the terminal 3 are successful, the executing terminal corresponding to the preemption task is determined as follows: terminal 2 and terminal 3. Namely: and determining the terminal which is successfully preempted as the executing terminal based on the preempted result.
S140, determining the execution terminal corresponding to the preempted task according to the preempted result of each terminal corresponding to the preempted task and the terminal information of the preempted task.
Specifically, since the preempted task may correspond to a plurality of terminals, a part of terminals corresponding to the preempted task may be preempted, and a part of terminals not preempted, that is, the preempted terminal information needs to be removed from the terminal information of the preempted task (the preempted terminal information is determined according to the preempted results of the terminals corresponding to the preempted task), so as to obtain the execution terminal corresponding to the preempted task.
In the embodiment of the present application, optionally, determining an execution terminal corresponding to a preempted task according to a preempted result of each terminal corresponding to the preempted task and terminal information of the preempted task, including: if the preemption task is determined to be successful to the first terminal according to the preemption result, and the terminal information of the preempted task comprises the first terminal, the first terminal is removed from the terminal information of the preempted task to obtain a residual terminal; and taking the remaining terminals as executing terminals corresponding to the preempted tasks.
Specifically, terminal information of the preempted task is obtained to obtain a terminal corresponding to the preempted task, if the preempted terminal exists in the terminal corresponding to the preempted task, the preempted terminal is removed from the terminal corresponding to the preempted task, and the rest terminal is determined to be an executing terminal corresponding to the preempted task.
For example, if the terminal corresponding to the preemption task B is: terminal 2, terminal 3 and terminal 4; the terminals corresponding to the preempted task a are terminal 1 and terminal 2. If the preemption task B preempts the terminal 2 successfully, the executing terminal corresponding to the preempted task A is the terminal 1.
S150, determining absolute account book data in a memory according to the execution terminal corresponding to the preempted task and the execution terminal corresponding to the preempted task, and updating the absolute account book data in the database based on the absolute account book data in the memory; and the absolute account book data in the database are used for controlling the actual terminal.
The absolute account book data reflect the information such as the preemption result of each task, the latest execution terminal corresponding to each task is stored in the absolute account book data, and the absolute account book data in the database are used for controlling the actual terminal. For example, the absolute ledger data includes the task being executed and the execution terminal corresponding to the task being executed, and it should be noted that, the channel information, the execution time, and the like of the terminal corresponding to the task may be located in the absolute ledger data.
In the embodiment of the application, the absolute account book data in the database can be read by other services, and the other services can control the terminal according to the absolute account book data.
Specifically, after the execution terminal corresponding to the preemption task and the execution terminal corresponding to the preempted task are obtained, the execution terminal corresponding to the preemption task and the execution terminal corresponding to the preempted task are placed in the absolute account book data in the memory, and then the absolute account book data in the database is updated based on the absolute account book data in the memory, so that the absolute account book data in the database comprises the latest task and the terminal to be executed, and other services can control the terminal according to the absolute account book data.
The technical scheme of the embodiment of the application comprises the following steps: if a task preemption request is received, determining preemption tasks and target terminals to be preempted by the preemption tasks according to the task preemption request; the preemption task corresponds to at least one target terminal; determining a preemption result according to the preemption task being executed on the target terminal and the priority of the preemption task; determining an execution terminal corresponding to the preemption task according to preemption results of the terminals corresponding to the preemption task; determining an execution terminal corresponding to the preempted task according to the preempted result of each terminal corresponding to the preempted task and the terminal information of the preempted task; determining absolute account book data in a memory according to the execution terminal corresponding to the preempted task and the execution terminal corresponding to the preempted task, and updating the absolute account book data in a database based on the absolute account book data in the memory; and the absolute account book data in the database are used for controlling the actual terminal. According to the technical scheme, absolute account book data are placed in the database, the terminal is controlled based on the absolute account book data through other services, the task preemption process on the terminal is achieved, the data in the database can be used as a recovery basis when a memory is in a problem, and the problem of data loss is avoided.
Example two
Fig. 2 is a flowchart of a preemption method of a task terminal according to a second embodiment of the present application, where the embodiment of the present application is optimized based on the foregoing embodiment.
As shown in fig. 2, the method in the embodiment of the present application specifically includes the following steps:
S210, if a task preemption request is received, determining a preemption task and a target terminal which needs preemption of the preemption task according to the task preemption request; and the preemption task corresponds to at least one target terminal.
When the preemption service obtains preemption task data through the interface, the preemption task data is decomposed, information such as a terminal set and priority corresponding to the preemption task is obtained respectively, and after each terminal corresponding to the preemption task is obtained, the data of each terminal is added into the terminal list data set and the task terminal data set, so that the follow-up use of the terminal data is facilitated.
S220, determining a preemption result according to the priority of the preempted task and the preemption task being executed on the target terminal.
Preemption for the target terminal may be to judge the priority of the preempted task and the preempted task being executed in different audio channels (background sound/foreground sound), if the priority of the preempted task is higher, the preemption is successful, otherwise the preemption fails.
S230, determining the execution terminal corresponding to the preemption task according to the preemption result of each terminal corresponding to the preemption task.
If the preemption is successful, the target terminal with the successful preemption is determined as the execution terminal corresponding to the preemption task. And storing the preemption tasks to an execution task set corresponding to the target terminal aiming at the target terminal with successful preemption, then clearing the tasks to be executed of the target terminal, carrying out priority sequencing on the tasks (except the preemption tasks) corresponding to the target terminal, and determining the tasks to be executed corresponding to the target terminal according to the sequencing result. The task to be executed corresponding to the target terminal can be used for the recovery process of other tasks after the subsequent execution task is finished.
S240, determining an executing terminal corresponding to the preempted task according to the preempted result of each terminal corresponding to the preempted task and the terminal information of the preempted task.
S250, determining absolute account book data in a memory according to the execution terminal corresponding to the preempted task and the execution terminal corresponding to the preempted task, and updating the absolute account book data in a database based on the absolute account book data in the memory; and the absolute account book data in the database are used for controlling the actual terminal.
After the execution terminal corresponding to the preempted task and the execution terminal corresponding to the preempted task are obtained, the execution terminal is used as absolute account book data, and the absolute account book data is updated to the redis service. And updating the data in the relative account book into redis, wherein the relative account book data is the original data of the task, such as task information, terminal information corresponding to the task, and the like.
In one particular embodiment, the process of determining absolute ledger data and updating the absolute ledger data into the database may be: if task 1 exists, task 2 corresponds to terminal 1, task 2 corresponds to terminal 2 and terminal 3. When task 3 corresponds to a total of 3 terminals, terminal 1 and terminal 2, and terminal 4, task 3 is ready to preempt task 1 and task 2 at this time and has a higher priority than both tasks. In this time, the task 3 is successfully preempted, data is ready to be pushed to redis, the terminals 1 in the task 1 are deleted and updated one by one, no terminals are in the task 1, but the task is reserved, the terminals 2 in the task 2 are deleted and updated, and only one terminal of the terminals 3 is reserved; task 3 has terminals 1,2,4, respectively, where absolute ledger data is obtained, after which the absolute ledger data is updated into redis.
It should be noted that, in updating absolute account book data, relative account book data basically does not change, unless the data in the task is updated after the task is established, the information in the memory is synchronized to the redis server in real time at this time. The relative ledger data may be used for re-recovery after data loss.
S260, when the task end information is received, the end task and the end terminal corresponding to the end task are obtained from the relative ledger data.
In the embodiment of the application, if the task ending information sent by the center service is received, the ending task is determined, and then the ending task is obtained from the relative account data, in this case, if the server is normal all the time, the ending task can be directly obtained from the memory, if the server has a problem before, the ending task can be obtained from the relative account data in the database, after the ending task is obtained, the ending terminal corresponding to the ending task is obtained, that is, the ending task is not executed on the ending terminal any more is needed to be realized later.
S270, determining the task with the highest priority from the tasks to be executed corresponding to the ending terminal.
Specifically, the tasks to be executed corresponding to the end terminal are subjected to priority ranking, and then the task with the highest priority is determined, wherein the task with the highest priority is the next task to be executed after the end task on the end terminal is ended.
S280, updating the execution terminal corresponding to the task with the highest priority in the absolute account book data in the memory, and deleting the execution terminal corresponding to the ending task.
It should be noted that, if the memory has no absolute account book data (e.g., the server is down), the absolute account book data may be extracted from the database into the memory.
Specifically, after determining the task with the highest priority through S270, the task with the highest priority needs to be executed by the ending terminal, and then the ending terminal is determined as the executing terminal corresponding to the task with the highest priority.
In an embodiment of the present application, optionally, before updating the absolute account book data in the memory, the method further includes: acquiring first attribute information of the ending terminal from the terminal list set and acquiring second attribute information of the ending terminal from the relative account data; the terminal list set stores information corresponding to each terminal; and if the first attribute information and the second attribute information are matched, executing the step of updating the absolute account book data in the memory.
Wherein the first attribute information and the second attribute information each reflect attribute information of the terminal, for example, identification information of the terminal.
Specifically, the first attribute information of the terminal is obtained from the terminal list set, the second attribute information of the terminal is obtained from the relative account book data, then the two attribute information are matched, and the subsequent steps are carried out after the matching is successful, so that the problem of mistaken terminal caused by too much data in the memory can be avoided.
S290, updating the absolute account book data in the database based on the absolute account book data in the memory.
After the execution terminal corresponding to the task with the highest priority is obtained, the task with the highest priority is updated in absolute account book data in a memory, and the ending task is deleted in the absolute account book data, at this time, the latest execution terminal corresponding to each task is stored in the absolute account book data, and then the absolute account book data in a database is updated based on the absolute account book data in the memory, so that other services control the terminal according to the absolute account book data in the database.
In an embodiment of the present application, optionally, the method further includes: if the information corresponding to the preemption task is obtained, updating the relative account information in the memory according to the information corresponding to the preemption task; the relative account book information reflects terminal information corresponding to each task respectively; if the information corresponding to the ending task is obtained from the relative account book data, deleting the information corresponding to the ending task from the relative account book information in the memory; based on the relative account information in the memory, updating the relative account information in the database to re-read the data from the database after the data in the memory is lost.
In the embodiment of the application, when the preemptive task is obtained, or the modification request for the task is obtained, a certain task is modified, or the request for ending the task is obtained, namely, various changes for the task such as ending the task are not executed later, the relative account book data in the database can be synchronously updated, so that the latest task data are stored in the relative account book data, and the lost data can be read from the database under the condition that the data in the memory are lost.
According to the scheme, on a data processing structure, terminals are taken as the root, each terminal corresponds to a task, a plurality of tasks exist, storage ordering is performed according to data priority, when the tasks are sent, only the terminals in the tasks needing to be operated are operated, terminal operation under the tasks is greatly reduced, tasks which are still being executed in a memory are restored after the current tasks are finished, and the integrity of the data is guaranteed to form a closed loop. In the distributed architecture, the processed data is stored in redis, the uniqueness of the data in the data is ensured by adopting a key value pair mode, and the data can be shared with other services.
