Detailed Description

Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

It should be appreciated that in embodiments of the present disclosure, the character "/" generally indicates that the context associated object is an "or" relationship. The terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

For example, for an application program running in a virtual machine, during the running of the application program, because the memory space occupied by the program information loaded into the method area of the memory is small, and in consideration of that the program information may be used multiple times in the application program, in order to avoid the influence of the repeated loading of the program information on the running efficiency of the program, the program information is not deleted after being loaded into the method area, so that the memory space is occupied by the program information, and the program information is not deleted in the method area until the application program finishes running. It can be appreciated that the constant occupation of the storage space by the program information in the method area may cause a waste of storage resources, and particularly, for some devices (such as vehicle devices) with relatively tight storage resources, the constant occupation of the storage resources in the method area may cause the devices to fail to efficiently utilize the limited storage resources. However, the related art lacks a method capable of timely recycling the storage space occupied by the above-mentioned program information.

The method may be performed by a terminal device, or by a computer, or by a server, or by other devices having data processing capabilities. The subject of execution of the method is not limited herein. In some embodiments, the execution body of the storage space reclaiming method provided in the embodiments of the present disclosure may be a terminal device (such as a vehicle-mounted computer) on a host vehicle.

Optionally, the terminal device may be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (personal digital assistant, PDA), or the like, and the specific type of the terminal device is not limited in the embodiments of the present disclosure.

In some embodiments, the server may be a single server, or may be a server cluster formed by a plurality of servers. In some implementations, the server cluster may also be a distributed cluster. The present disclosure is not limited to a specific implementation of the server.

The storage space reclamation method provided in the present disclosure is exemplified below.

Fig. 1 shows a flow chart of a storage space recycling method provided by the present disclosure, as shown in fig. 1, the method may mainly include the following steps:

s110: in response to the application program starting operation, an upper limit of the number of times of use of the target program information in the code file of the application program is determined.

Here, the target program information refers to a part of program information that is not recovered in the storage space occupied during the running of the application program, and the storage space recovery method provided by the present disclosure is mainly used for recovering the storage space occupied by the program information.

Alternatively, for an application program running in a virtual machine formation, the target program information is a part of information of a Method Area (Method Area) that needs to be loaded into the memory when in use. Here, the method section is a concept defined in the virtual machine specification for storing data such as class information, method information, constant pool, static variables, JIT-compiled code, and the like. Specifically, the object information in the embodiments of the present disclosure may include class information, method information, and the like.

In S110, after the application is started to run, an upper limit of the number of uses thereof may be determined for at least one target program information in the code file of the application. Here, the upper limit of the number of uses refers to the number of times that the target program information estimated in advance is used at most in the running period of the application program.

Alternatively, some of the target program information is used a fixed number of times in the running period of the application program, and thus the fixed number of times of use may be recorded in the code file as an upper limit of the number of times of use of the target program information, it being understood that the upper limit of the number of times of use is known for this kind of target program information. Specifically, program information whose upper limit of the number of uses is known may be defined as first type information, and in S110, after the application program is started to run, the type of the target program information may be determined from the code file of the application program, and then the upper limit of the number of uses of the target program information is acquired from the code file in response to the target program information belonging to the first type information. In the embodiment of the disclosure, a field for recording the upper limit of the number of uses of the first type information may be added to the code file, and when it is determined that the target program information belongs to the first type information, the field may be searched and identified in the code file, so as to determine the upper limit of the number of uses of the target program information.

Taking the initialization class in the code file as an example, the initialization class is used only once when a process in the starting process of the application program is created, and then is not used during the running of the application program, so that the initialization class belongs to the first type of information. In the code file, a field for recording the upper limit of the number of uses of the initialization class may be added, and the value of the field is 1, that is, the upper limit of the number of uses of the initialization class is 1. When the application program starts to run, the initialization class is determined to belong to the first type information, and then a field '1' corresponding to the initialization class is searched and identified in the code file, so that the upper limit of the using times of the target program information is determined to be 1.

In the embodiment of the disclosure, the known upper limit of the use times of the program information is defined as the first type information, and the upper limit of the use times of the program information is recorded in the code file, so that when an application program is started, the upper limit of the use times of the target program information can be quickly acquired from the code file under the condition that the target program information is determined to be the first type information, and the efficiency of determining the upper limit of the use times is improved.

Optionally, the number of times of use of some object program information in the operation period of the application program is not completely fixed, and the number of times of use of the object program information in the operation period of the application program is associated with the operation condition information of the application program. That is, the number of uses of the target program information in the operating cycle of the application may also be different for different operating condition information, that is, the upper limit of the number of uses of the target program information is generally unknown here. For this kind of information, the upper limit of the number of uses of the target program information may be predicted based on the running condition information of the application program.

Specifically, program information whose upper limit of the number of uses is unknown may be defined as the second type information. In S110, after the application program is started to run, the type of the target program information may be determined from the code file of the application program, the running condition information of the application program is determined in response to the target program information belonging to the second type information, and then the upper limit of the number of uses of the target program information is predicted based on the running condition information. In the case of the target program information whose number of uses is not fixed, in which there is a correlation between the number of uses of the target program information in the operation cycle of the application program and the operation condition information of the application program, the upper limit of the number of uses of the target program information can be accurately predicted based on the operation condition information.

Here, a specific process of predicting the upper limit of the number of uses of the target program information based on the running condition information will be further described in the following, and will not be described herein.

S120: the number of uses of the target program information is monitored during the running of the application program.

Optionally, in S120, a remaining usage number of the target program information may be set, where an initial value of the remaining usage number is an upper limit of the usage number of the target program information. Each time the target program information is monitored to be used, the remaining use times can be subtracted by 1.

Alternatively, in S120, the number of times of use of one piece of target program information may be set, the initial value of the number of times of use being 0. The number of times of use may be accumulated by 1 each time the target program information is monitored to be used.

S130: and recovering the storage space occupied by the target program information in response to the use times of the target program information reaching the upper limit of the use times.

Alternatively, when the remaining number of uses set in S120 becomes 0, it is indicated that the number of uses of the target program information reaches the upper limit of the number of uses. Or when the number of used times set in S120 is equal to the upper limit of the number of used times, that is, it is indicated that the number of used times of the target program information reaches the upper limit of the number of used times.

When the use times of the target program information reach the upper limit of the use times, the storage space occupied by the target program information can be recovered. Specifically, the target program information may be deleted from the memory into which it is loaded, thereby reclaiming the memory space occupied by the target program information. For example, for an application program running in virtual machine formation, when it is determined that the number of times of use of the target program information reaches the upper limit of the number of times of use, the target program information may be deleted in a method area of the memory, thereby reclaiming the storage space occupied by the target program information.

Alternatively, in S130, when the target program information is deleted from the memory into which it is loaded, other information that is only relied upon by the target program information may also be deleted from the memory.

It should be noted that, after S130, if the target program information still needs to be used continuously, the target program information may also be reloaded into the memory, and other information only relied on by the target program information may also be reloaded into the memory.

Alternatively, in the embodiment of the present disclosure, when the upper limit of the number of times of use of the target program information is predicted based on the running condition information, the running condition information may be input to a pre-trained upper limit number of times prediction model, and the upper limit of the number of times of use of the target program information may be output using the upper limit number of times prediction model.

Here, the upper limit number of times prediction model is an artificial intelligence model trained based on the operation condition information during the historical operation of the application program and the actual number of times of use of the target program information during the historical operation of the application program. After model training is completed, the upper limit number of times prediction model can obtain the upper limit of the use number of the target program information based on the running condition information of the application program in the current running period. According to the method and the device for predicting the use frequency upper limit of the target program information based on the running condition information by utilizing the pre-trained artificial intelligent model, the efficiency of the prediction process and the accuracy of the prediction result can be remarkably improved. In addition, the upper limit number of times prediction model is obtained by training based on the running condition information of the application program in the historical running period and the actual use number of the target program information in the historical running period of the application program, so that the result predicted by the upper limit number of times prediction model is more consistent with the actual use condition of the user, and a more targeted prediction result can be provided for each user.

Optionally, the running condition information includes at least one of a starting time point of the application program and a running application scenario of the application program. It should be noted that, at different starting time points, the user may have different usage requirements for some program information, so that the starting time point of the application program may be used as a basis for predicting the upper limit of the number of times of usage of the target program information. The running application scenes of the application program can comprise a front-end running scene and a background running scene, and the use requirements of the running application scenes are different in different running application scenes for certain program information, so that the running application scenes of the application program can be used as the basis for predicting the upper limit of the use times of the target program information.

Optionally, when the upper limit number of times of use of the target program information is output by using the upper limit number of times prediction model, the embodiment of the disclosure specifically includes: determining the running times of an upper limit times prediction model; responding to the operation times of the upper limit times prediction model being smaller than a preset operation times threshold value, and outputting preliminary estimated use times of the target program information by using the upper limit times prediction model; determining the estimated increase use times corresponding to the upper limit times prediction model; and taking the sum value of the preliminary estimated use times and the estimated increase use times as the upper limit of the use times of the target program information. Here, the operation frequency threshold may be determined according to actual design needs, when the operation frequency of the upper limit frequency prediction model is smaller than the preset operation frequency threshold, which indicates that the number of times the upper limit frequency prediction model is trained is smaller, the accuracy of the prediction result of the upper limit frequency prediction model is poor, so that the use frequency output by the upper limit frequency prediction model cannot be directly used as the upper limit of the use frequency of the target program information, but the use frequency output by the upper limit frequency prediction model needs to be used as the initial estimation use frequency, and the sum of the initial estimation use frequency and the estimated increase use frequency is used as the final upper limit of the use frequency, so that the target program information is prevented from being deleted in the memory too early due to the fact that the upper limit of the use frequency is too small, and further, the target program information is prevented from being repeatedly loaded when the target program information needs to be reused, which may ensure that the application program has higher operation efficiency.

In some embodiments of the present disclosure, the estimated increase in use is a predetermined fixed number of times, for example, the estimated increase in use is fixed at 2. Under the condition that the running times of the upper limit times prediction model are smaller than a preset running times threshold value, the primary estimated using times of outputting the target program information by using the upper limit times prediction model are summed with 2 each time, so that the upper limit of the using times of the target program information is obtained.

In some embodiments of the present disclosure, determining the estimated increased usage times corresponding to the upper bound times prediction model includes: and determining a difference value between the running times of the upper limit times prediction model and the running times threshold value, and determining the estimated increase use times corresponding to the upper limit times prediction model based on the difference value. Here, the estimated increase use number may be approximately proportional to the difference value, and the smaller the difference value is, the smaller the estimated increase use number is. As the number of operations of the upper limit number of operations prediction model increases, the difference between the number of operations of the upper limit number of operations prediction model and the threshold of the number of operations decreases, and the number of times the upper limit number of operations prediction model is trained increases, and the accuracy of the prediction result output by the upper limit number of operations prediction model increases gradually, so that the estimated increase number of operations needs to be dynamically adjusted based on the change of the difference, so that the sum of the preliminary estimated increase number of operations and the estimated increase number of operations is closer to the actual upper limit of the number of operations.

Optionally, after predicting the upper limit of the number of uses of the target program information based on the operation condition information, the storage space reclamation method further includes: counting the actual use times and the predicted upper limit of the use times of the target program information in a plurality of running periods of the application program in a preset time period; when it is determined that the target program information is equal to and unchanged from a plurality of actual usage times and a plurality of predicted usage times upper limits in a preset time period, the target program information is recorded as first type information, and one usage time upper limit predicted by the target program information in the preset time period is recorded in a code file. It can be understood that the number of actual uses of the target program information is equal to and unchanged from the number of predicted upper limits of the number of uses in the preset time period, which means that the number of uses of the target program information during the running of the application program is also fixed, so that the target program information can be subdivided into the first type information and the upper limits of the number of uses thereof can be recorded in the code file, and in the subsequent use process of the application program, the upper limits of the number of uses of the target program information can be obtained directly and quickly in the code file without predicting the upper limits of the number of uses of the target program information based on the running condition information, which can promote the efficiency of determining the upper limits of the number of uses.

Fig. 2 is a schematic flow chart of another storage space recycling method provided by the present disclosure, and as shown in fig. 2, the method may mainly include the following steps:

s210: in response to the application program starting operation, an upper limit of the number of times of use of the target program information in the code file of the application program is determined.

S220: the number of uses of the target program information is monitored during the running of the application program.

S230: and recovering the storage space occupied by the target program information in response to the use times of the target program information reaching the upper limit of the use times.

Here, the specific execution steps of S210 to S230 may refer to the corresponding contents in S110 to S130, and will not be described herein.

S240: after the application program finishes running, the actual use times of the target program information in the current running period of the application program and the running condition information in the current running period of the application program are used as new training data of the upper limit times prediction model.

It can be understood that the actual usage times of the running condition information and the target program information corresponding to each running period of the application program can be used as new training data to retrain the upper limit number of times prediction model, so that the prediction result of the upper limit number of times prediction model is more accurate, and the upper limit number of times of use can be predicted more accurately.

Fig. 3 is a schematic flow chart of a training method of an upper limit number of times prediction model provided by the present disclosure, where the upper limit number of times prediction model is used in the storage space recovery method provided in the foregoing some embodiments, as shown in fig. 3, the method may mainly include the following steps:

s310: the operation condition information in the history operation period of the application program is input into an upper limit number prediction model, and an upper limit number of use of the target program information is output by using the upper limit number prediction model.

S320: and adjusting parameters of the upper limit number prediction model based on the difference between the output upper limit number of times of use and the actual number of times of use of the target program information in the historical operating period.

Alternatively, the function loss may be determined based on a difference between the output upper limit of the number of uses and the actual number of uses of the target program information during the history of operation; and adjusting parameters of the upper limit number prediction model based on the determined function loss.
