In view of the problems in the related art, the present disclosure proposes a program instance management method. FIG. 1 is a flow chart of a program instance management method, as shown in FIG. 1, the program instance management method at least includes the following steps:
S110, if a starting instruction corresponding to the target program is acquired, creating a program instance file with an association mapping relation with the target program in the disk file.
Step S120, determining instance information of a program instance corresponding to the target program, and storing the instance information into a program instance file so as to realize management of the program instance through the program instance file.
In the method and the device provided by the exemplary embodiment of the disclosure, the program instance file with the association mapping relation with the target program is created in the disk file, and the program instance file is used for subsequent management of the program instance, so that the condition that the management of the program instance must depend on a third party management program in the prior art is avoided, the complexity of the management of the program instance is reduced, and the efficiency of the management of the program instance is improved.
The steps of the program instance management method are described in detail below.
In step S110, if a start instruction corresponding to the target program is acquired, a program instance file having an association mapping relation with the target program is created in the disk file.
In an exemplary embodiment of the present disclosure, a target program refers to a program that a user needs to start, for example, a user may install chat software on a terminal according to needs, after the chat software is installed successfully, all files under a corresponding installation directory are chat programs, and a start entry exists in a plurality of chat programs, where the start entry is the target program, when the user touches the target program, the terminal receives a start instruction about the target program, and at this time, a program instance is generated to store instance information.
It should be noted that, one target program may correspond to a plurality of program instances, specifically, a user may log in to a chat program using a plurality of chat accounts, and then a plurality of program instances corresponding to the target program exist, where the plurality of program instances may store instance information corresponding to the plurality of chat accounts respectively.
The disk file refers to a file existing in a computer, and the association mapping relationship refers to a corresponding relationship between a target program and a program instance file, which is worth noting that the program instance file may be directly created in the disk file, or the program instance file may be created in a specific sub-file of the disk file, for example, the program instance file may be created in an x sub-file of a D disk file, which is not particularly limited in the present exemplary embodiment.
For example, the user clicks the start entry in the chat program, that is, the user clicks the target program for starting the chat, and then obtains the start instruction corresponding to the target program, so as to create the program instance file a with the association mapping relation with the target program in the computer D disk file.
In an alternative embodiment, creating a program instance file with an association mapping relation with the target program in the disk file includes: and determining an identifier corresponding to the target program, and creating a program instance file with an association mapping relation with the target program in the disk file according to the identifier.
The identifier may be a character string used in creating the program instance file, where the character string corresponds to the target program and has a unique corresponding relationship with the target program, and the program instance file created by using the identifier is a program instance file having an association mapping relationship with the target program.
Specifically, the identifier may be a unique identifier (a randomly generated non-repeating character string), or may be a combination of a creation time of a process generated when the target program is started and a process number, which is not particularly limited in the present exemplary embodiment.
Based on this, the concrete naming of the program instance file may take the form of instance_file_id, where instance_file represents that the file is a program instance file and id refers to an identifier.
For example, the identifier may be a unique identifier, based on which, the identifier corresponding to the target program is determined to be xxxxx, and according to the identifier, a program instance file a having an association mapping relationship with the target program may be created in a D disk file of the computer.
In the present exemplary embodiment, on the one hand, the program instance file is created by using the identifier corresponding to the target program, so that it is ensured that the program instance file and the target program have an association mapping relationship; on the other hand, the program instance file is created in the disk file, so that the situation that the program instance must be realized by a third party management program in the subsequent process of managing the program instance is avoided, the complexity of the management program instance is reduced, and the efficiency of the management program instance is improved.
In an alternative embodiment, after creating the program instance file with the association mapping relation with the target program in the disk file, the method further includes: creating a target object with a single mapping relation with the program instance file by using the identifier; wherein the life cycle of the target object and the process corresponding to the target program is the same.
The target object refers to an object having the same life cycle as a process corresponding to the target program, specifically, the target object may be a global object, and is created by using a related function in a programming language, which is worth noting that a program instance may be abnormally exited, which may cause a program instance file corresponding to the program instance to remain in a disk file, thereby causing a large amount of occupation of the disk file.
Based on this, in order to solve the above-described problem, it is necessary to create a target object having a single mapping relation with the program instance file, and in the subsequent determination of whether the program instance file is a file remaining in the disk file, it is possible to determine whether the program instance corresponding to the program instance file has been abnormally exited by determining whether the target object exists.
For example, using the identifier xxxxxxx, a target object www having a single mapping relationship with the program instance file a is created, where it is worth noting that the target object www and the process corresponding to the target program have the same life cycle.
In this exemplary embodiment, by creating the target object having a single mapping relationship with the program instance file, the occurrence of the situation that the program instance file remains in the disk file when the program instance has been abnormally exited is avoided, and in addition, the occurrence of errors and confusion in the subsequent process of managing the program instance file is avoided.
In step S120, instance information of a program instance corresponding to the target program is determined, and the instance information is stored in a program instance file, so that management of the program instance is achieved through the program instance file.
In an exemplary embodiment of the present disclosure, the instance information refers to information describing the program instance, specifically, the program instance information may be a process number corresponding to a process running the target program, the program instance information may also be an open communication pipe for connection with other program instances to use, the program instance information may also include a name of the target object to determine whether the target object exists, the program instance information may also be information of a user, for example, in a chat program, the program instance information may be account information of a user login account.
After determining the instance information corresponding to the program instance, the instance information may be stored in the program instance files, and then the program instance may be managed by the program instance files storing the instance information.
For example, determining instance information corresponding to a target program may be as follows, { pid: xxx; uid: yyy; ipc, zzz; the content in }, where }, is instance information, where instance information is usually some key-like value pairs, pid indicates a process number corresponding to a process running the target program, xxx indicates a specific value of the process number, uid indicates information of a user, yyyy indicates a specific value of user information, for example, may be an account nickname of the user, ipc indicates an open communication pipe, zzz is identification information of an open channel, and exist_key is a key corresponding to whether the target object exists or not, and www is used to indicate whether the target object exists or not.
The example information is stored in the corresponding program instance file, so that the corresponding program instance can be managed through the program instance file.
In an alternative embodiment, fig. 2 is a schematic flow chart of storing instance information in a program instance file in a program instance management method, and as shown in fig. 2, the method at least includes the following steps: in step S210, all program instance files having an association mapping relationship with the target program are determined from the disk files, and target objects having a single mapping relationship with all program instance files respectively are determined.
However, before the instance information is stored in the program instance file, it is required to determine whether the program instance file is a file remaining in the disk file after the program instance is abnormally exited, and further, it is required to acquire all program instance files having an association mapping relationship with the target program, and it is required to determine the target objects having a single mapping relationship with the 4 program instance files, respectively, if it is determined that the 4 program instance files have an association mapping relationship with the target program.
For example, all program instance files having an association mapping relationship with the target program S are determined from the disk files, specifically, all program instance files include a program instance file_file_xx1, a program instance file_file_xx2, and a program instance file_file_xx3, and target objects having a single mapping relationship with the program instance file_file_xx1, target objects having a single mapping relationship with the program instance file_file_xx2, and target objects having a single mapping relationship with the program instance file_file_xx3 are determined respectively.
In step S220, if there is a target object having a single mapping relationship with the program instance file, the instance information of the program instance corresponding to the target program is determined, and the instance information is stored in the program instance file.
If there is a target object with a single mapping relation with the program instance file, it is proved that the program instance file is not a file remaining in the disk file, and at this time, the instance information may be stored in the program instance file.
For example, there is a target object a having a single mapping relationship with the program instance file instance_file_xx1, at which point instance information may be stored into the program instance file instance_file_xx1.
In step S230, if there is no target object having a single mapping relationship with the program instance file, the program instance file is deleted.
Since the life cycle of the target object and the process corresponding to the target program is the same, the target object is not existed along with the exit of the target program no matter the target program is normally exited or abnormally exited, and further, when the target object with a single mapping relation with the program instance file does not exist, the target program is proved to be exited at the moment, therefore, the program instance file corresponding to the target program, which is remained in the disk file, needs to be deleted.
For example, there is no target object having a single mapping relationship with the program instance file instance_filexx2 and with the program instance file instance_filexx3, at which time the program instance file instance_filexx2 and the program instance file instance_filexx3 are deleted from the disk file.
In the present exemplary embodiment, before storing the instance information in the program instance file, the determination is made as to whether there is a target object having a single mapping relationship with the program instance file, so that the logic of storing the instance information in the program instance file is perfected, and the situation that when there is no target object having a single mapping relationship with the program instance file, the instance information is still stored in the program instance file is avoided.
In an alternative embodiment, the management of the program instance through the program instance file includes: and if a change instruction corresponding to the target program is acquired, changing the instance information of the program instance corresponding to the target program.
The change instruction refers to an instruction for changing the instance information, for example, in a chat program, there is a function of logging out or logging in other accounts, when a user touches a logging out control or a control corresponding to a function of logging in other accounts, a change instruction corresponding to a target program in the chat program is obtained, new instance information is carried in the change instruction, and then the stored instance information is changed according to the new instance information.
For example, the instance information of the program instance corresponding to the target program stored in the disk file is { pid: xxx; uid: yyy; ipc, zzz; if at this time, when a user touches a control corresponding to the function of logging in other accounts, a change instruction is acquired, other account information carried in the change instruction is zzz, and then a value yyy corresponding to the uid in the instance information is changed to zzz.
In this exemplary embodiment, if the change instruction corresponding to the target program is obtained, the instance information can be changed, which avoids the need of implementing by means of a third party management program in the process of changing the instance information in the prior art, reduces the complexity of changing the instance information, and further improves the efficiency of changing the instance information.
In an alternative embodiment, the management of the program instance through the program instance file includes: if a normal exit instruction corresponding to the target program is acquired, deleting the program instance file corresponding to the target program in the disk file.
The normal exit instruction refers to an instruction for exiting the target program normally, for example, if the running target program is a chat program, the normal exit instruction may be an instruction obtained after the user touches the exit chat window.
When a normal exit instruction is received, the program instance file corresponding to the target program stored in the disk file needs to be deleted, so that the program instance file is prevented from remaining in the disk file under the normal exit condition.
For example, if the running target program is a chat program, after the control for exiting the chat window is touched, a normal exiting command may be obtained, and at this time, the program instance file instance_file_xx4 corresponding to the target program stored in the disk file is deleted.
In this exemplary embodiment, when the normal exit instruction is acquired, the program instance file corresponding to the target program is deleted in the disk file, so that the residue of the program instance file in the disk file is avoided under the normal exit condition, unnecessary memory occupation is reduced, and in addition, the accuracy of the subsequent management program instance file is improved.
In an alternative embodiment, fig. 3 is a schematic flow chart of implementing management of a program instance by a program instance file in a program instance management method, and as shown in fig. 3, the method at least includes the following steps: in step S310, if a restart instruction corresponding to the target program is acquired, all program instance files having an association mapping relationship with the target program are acquired from the disk file.
The restart instruction refers to an instruction sent when the target program is restarted, for example, if the target program is a chat program, the user may restart the chat program after starting the chat program for the first time, and then obtain the restart instruction, and after obtaining the restart instruction, obtain all program instance files corresponding to the chat program from the disk file D, where the program instance files include a program instance file instance_file_xx5, a program instance file instance_file_file_xx6, a program instance file instance_file_xx7, and a program instance file instance_file_xx8.
In step S320, it is determined whether there is a target object having a single mapping relationship with the program instance file to obtain a determination result, and all the program instance files are filtered according to the determination result to obtain the target program instance file.
After all program instance files corresponding to the target program are acquired, whether the target object with a single mapping relation with the program instance files exists or not needs to be judged, so that the acquired program instance files are screened according to a judging result, and program instance files remained in the disk files are screened.
For example, it is determined whether the target object corresponding to the program instance file instance_filexx5 } is present or not to obtain the determination result a1, it is determined whether the target object corresponding to the program instance file instance_filexx6 } is present or not to obtain the determination result a2, it is determined whether the target object corresponding to the program instance file instance_filexx7 } is present or not to obtain the determination result a3, it is determined whether the target object corresponding to the program instance file instance_filexx8 } is present or not to obtain the determination result a4, and the program instance file instance_filexx5, the program instance file instance_filexx6 } and the program instance file instance_filexx8 } are screened according to the determination result a1, the determination result a2, the determination result a3 and the determination result a 4.
In step S330, the number of the object program instance files is determined to obtain a number determination result, and the object program is executed according to the number determination result.
The number judgment result refers to a result obtained after the number of the object program instance files is judged, and the object program is correspondingly executed according to the number judgment result.
For example, the program instance file is instance_file_xx5 } obtained by filtering the program instance file instance_file_xx5 }, the program instance file instance_file_xx6 }, the program instance file instance_file_xx7 } and the program instance file instance_file_xx8 }, and the program instance file instance_file_xx5 } is the target program instance file.
And judging the number of the object program instance files, wherein the number judgment result is that one object program instance file exists, and further executing the object program correspondingly according to the number judgment result.
In the present exemplary embodiment, when a restart instruction is acquired, on the one hand, program instance files are screened according to a judgment result, so that the influence of program instance files remained in disk files on an execution target program is avoided; on the other hand, according to the number judgment result, the target program is executed, and the logic of executing the target program is perfected.
In an alternative embodiment, fig. 4 is a schematic flow chart of a program instance management method for executing a target program, and as shown in fig. 4, the method at least includes the following steps: in step S410, if the number of the program instance files is determined to be not present, a program instance file having an association relationship with the target program is created in the disk file, so as to store instance information in the program instance file.
When the number judgment result shows that the target program instance file does not exist, it is proved that the program instance file corresponding to the target program is not created in the disk file at the moment, so that the program instance file related to the target program needs to be created in the disk file, and then the instance information is stored in the program instance file.
For example, if the number of program instance files corresponding to the target program a do not exist as a result of the number determination, a program instance file instance_file_xx7 having an association relationship with the target program a is created in the D disk file, so as to store instance information in the program instance file instance_file_xx7.
In step S420, if the number of the target program instance files exist as a result of the number determination, establishing communication between the background program instance and the target program instance; the background program instance is evoked when a restarting instruction is acquired, and the target program instance corresponds to a target program instance file.
If the number of the object program instance files exist as a result of the judgment, the instance information can be stored in the object program instance files, and when the instance information is stored in the object program instance files, communication between the background program instance and the object program needs to be established, and specifically, the process of establishing communication can be realized by utilizing a communication channel in the instance information stored in the object program instance files.
The background program instance refers to a program instance corresponding to a program which cannot be perceived by a user when a restart instruction is acquired, but the computer is actually running, and the target program instance refers to a program instance corresponding to a target program instance file.
For example, when the target program is a chat program, if the number determination result is that there is one target program instance file instance_file_xx8, then the communication channel in the target program instance file instance_file_xx8 is utilized to establish the communication between the target program instance corresponding to the target program instance file and the background program instance.
In step S430, an instruction to execute the target program is sent to the target program instance using the background program instance to execute the target program.
After communication between the background program instance and the target program instance is established, the background program instance sends an instruction for executing the target program to the target program instance, and at the moment, the target program is executed after the instruction for executing the target program is acquired.
For example, the target program is a chat program, after communication between the background program instance and the target program instance is established, the background program instance sends an instruction for executing the chat program to the target program instance, at this time, the chat program is executed, and a corresponding chat window is displayed in the computer.
In step S440, if the number of object program instance files exist, instance information corresponding to the object program instance files is displayed.
And if the number judgment result shows that a plurality of target program instance files exist, displaying instance information corresponding to the plurality of target program instance files.
For example, if the number of the target program is that there are multiple target program instance files, specifically, the target program instance files include instance_file_xx9 } and target program instance file instance_file_xx10 } and it is proved that there are two chat accounts that have been logged in at this time, and chat information corresponding to the chat accounts is stored in the two target program instance files, so that account information xxx in instance information corresponding to the target program instance file instance_file_xx9 } is displayed, and account information ccc in instance information corresponding to the target program instance file instance_file_xx10 } is also displayed, so that a user can select which account information to use, and after the user selects the account information, a chat window corresponding to the account information is opened.
In the present exemplary embodiment, according to the number judgment result, the corresponding execution target program perfects the execution logic of the target program.
In the method and the device provided by the exemplary embodiment of the disclosure, the program instance file with the association mapping relation with the target program is created in the disk file, and the program instance file is used for subsequent management of the program instance, so that the condition that the management of the program instance must depend on a third party management program in the prior art is avoided, the complexity of the management of the program instance is reduced, and the efficiency of the management of the program instance is improved.
