Fig. 1 is a schematic diagram of a detection flow of memory leak provided in an embodiment of the present disclosure, where the embodiment of the present disclosure is applicable to a situation of detecting memory leak, and the method may be executed by a detection apparatus of memory leak, where the apparatus may be implemented in a form of software and/or hardware, and optionally implemented by an electronic device, where the electronic device may be a mobile terminal, a PC terminal, or a server.

As shown in fig. 1, the method includes:

and S110, controlling the target equipment to periodically execute a setting operation task.

The target device may be understood as a target terminal, and the target terminal may be a mobile terminal of any operating system, for example, a mobile phone terminal of an Android operating system. And setting an operation task for simulating the operation behavior of the user on the terminal. Taking an Application (APP) simulating a user to operate the mobile terminal as an example, the setting operation tasks corresponding to different applications are different, and if an image processing Application is taken as an example, the setting operation task may be an operation behavior of processing an original image by using various beauty special effect functions.

Specifically, a memory leak detection script program may be set in advance at the PC, the PC is connected to the target device, and the memory leak detection script program is executed at the PC, so that the target device is controlled, and the target device is controlled to periodically execute the operation task according to a preset cycle number or an execution duration. The memory leak detection script program may be understood as a program code simulating a user operating a target device.

Optionally, the manner of periodically executing the setting operation task by the control target device may be: configuring cycle times or execution duration; the control target device executes a set operation task periodically based on the cycle number; or the control target device periodically executes the setting operation task within the execution duration.

The number of cycles may be any number of times, and may be, for example, 100 times, 300 times, 500 times, or the like. The execution time length may be any time length, and for example, may be N times, such as 100 times, 300 times, 500 times, etc., of the time length required for executing the setting operation task of one cycle. According to the embodiment, whether the memory leak exists during the execution of the set operation task can be effectively detected by periodically executing the set operation task based on the cycle number or the execution duration of the set operation task, and the accuracy of detecting the memory leak is improved.

Optionally, the setting operation task includes a plurality of sub-tasks, and the manner for the control target device to periodically execute the setting operation task may be: determining the interval duration of every two adjacent subtasks in the plurality of subtasks; and in the execution period of each set operation task, after the target terminal completes one subtask, pausing the interval duration and continuing to execute the next subtask.

The interval duration is determined by the response duration of the target terminal to the previous subtask. It should be noted that, since the set operation task includes a plurality of subtasks, the target terminal needs a corresponding response time after each subtask is executed. Therefore, the interval duration of every two adjacent subtasks in the multiple subtasks can be predetermined, so that when the subtasks are actually executed, after the target terminal completes one subtask, the next subtask is executed after the interval duration elapses, that is, the next subtask is executed again after the interval duration elapses before the next subtask is executed. In this embodiment, each subtask may be characterized by a screen coordinate, that is, in the current subtask, the target device is controlled by triggering a position corresponding to the screen coordinate.

In the embodiment, in the execution period of each set operation task, after the target terminal completes one subtask, after the interval duration elapses, the next subtask is executed again, and the response duration required by the target device after each execution of the subtask is considered, so that the manner of controlling the target device to periodically execute a plurality of subtasks better meets the actual situation, and further, whether memory leakage exists in the subsequent subtasks or not is conveniently detected.

And S120, reading the memory information of the target equipment after the execution of the set operation task is finished, and obtaining a memory information set.

The memory information may be a memory space occupied by the currently detected application program after the setting operation task of one cycle is executed, for example, the memory information may be 64125 kilobytes. Correspondingly, the memory information set may be a set of memory information occupied by the currently detected application program after the set operation task is periodically executed. For example, if the setting operation task is executed in three cycles, the corresponding memory information sets may be 64125 kbytes, 64273 kbytes, and 64501 kbytes.

Optionally, the manner of reading the memory information of the target device after the execution of the set operation task is completed and obtaining the memory information set may be: and in the process of periodically executing the set operation task by the target equipment, reading the memory information of the target equipment every first set time length to obtain a memory information set.

Specifically, in the process of periodically executing the setting operation task, the memory information of the target device may be periodically (every first set time length) read and recorded. The reading period of the memory information is greater than the execution period of the set operation task, that is, the first set duration is greater than the execution period of the set operation task. For example, if it takes 2 seconds to execute the setting operation task of one cycle, the read cycle of the memory information may be 2.5 seconds. In addition, the memory information can be read and recorded before the setting operation task of the first period is executed. The recording and storing mode of the memory information can be to record the memory information after executing the set operation task according to the row or the column and store the memory information in the form of a file, so as to facilitate the subsequent extraction and operation of the memory information set and facilitate the positioning of whether the set operation task has memory leakage.

In this embodiment, in the process of periodically executing the setting operation task, the memory information of the target device is read every first set duration, so that the memory information corresponding to the execution of the setting operation task can be accurately read.

And S130, determining a memory leakage result corresponding to the set operation task based on the memory information set.

Wherein the memory leak result includes the existence of a memory leak or the absence of a memory leak. In this embodiment, the memory leakage result corresponding to the set operation task may be determined by counting the memory information in the memory information set and determining whether the counted memory information exceeds the set threshold, or the memory leakage amount may be counted according to the memory information set, and the ratio of the memory leakage amount to the total time length for executing the set operation task is calculated, that is, the memory leakage result corresponding to the set operation task is determined by calculating the memory leakage rate.

Optionally, the mode of determining the memory leak result corresponding to the set operation task based on the memory information set may be: extracting the memory information with the set quantity which is ranked in the memory information set in the front as a first memory information subset; extracting the memory information with the set quantity which is ranked backwards in the memory information set as a second memory information subset; and determining a memory leakage result corresponding to the set operation task based on the first memory information subset and the second memory information subset.

It should be noted that the memory information in the memory information set is stored in rows or columns according to the order of executing the set operation task, so that the memory information in the memory information set with the set number ordered in the top may be extracted row by row or column by column according to a pre-stored manner, and used as the first memory information subset. And extracting the memory information with the set quantity which is arranged at the back in the memory information set row by row or column by column, and taking the memory information as a second memory information subset. The set number may be 10 or 20, which is not limited in this embodiment. For example, if the execution cycle is 100, the set number is 10, and the storage manner by row is taken as an example, the memory information corresponding to the set operation task executed in the first 10 cycles may be extracted by row as the first memory information subset, and the memory information corresponding to the set operation task executed in the last 10 cycles may be extracted by row as the second memory information subset.

In this embodiment, by extracting the first memory information subset and the second memory information subset, and determining the memory leak result corresponding to the set operation task based on the first memory information subset and the second memory information subset, the efficiency and accuracy for detecting whether the set operation task has a memory leak can be improved.

Optionally, the manner of determining the memory leakage result corresponding to the set operation task based on the first memory information subset and the second memory information subset may be: extracting first memory statistical information in the first memory information subset and second memory statistical information in the second memory information subset; determining the memory leakage amount according to the second memory statistical information and the first memory statistical information; if the memory leakage amount is larger than or equal to a first set threshold value, setting that the memory leakage exists in the operation task; and if the memory leakage amount is smaller than a first set threshold value, setting that the operation task has no memory leakage.

The memory statistical information includes maximum memory information, minimum memory information or average memory information. Specifically, memory statistics may be performed on the first memory information subset and the second memory information subset, and correspondingly, the first memory statistical information and the second memory statistical information may be obtained correspondingly. The memory statistics may be maximum memory statistics, minimum memory statistics, average memory statistics, and the like. After the first memory statistical information and the second memory statistical information are obtained, taking the difference between the second memory statistical information and the first memory statistical information as the memory leakage amount, comparing the memory leakage amount with a first set threshold value, and if the memory leakage amount is greater than or equal to the first set threshold value, setting that the memory leakage exists in the operation task; and if the memory leakage amount is smaller than a first set threshold value, setting that the operation task has no memory leakage. The first set threshold may be any value, and may be, for example, 10 megabits, 12 megabits, or the like.

In this embodiment, the memory leakage amount is determined according to the second memory statistical information and the first memory statistical information, and whether the memory leakage exists in the set operation task is determined by judging whether the memory leakage amount exceeds the first set threshold, so that whether the memory leakage exists in the set operation task can be effectively and accurately detected, and the accuracy of detecting the memory leakage is improved.

Optionally, the manner of determining the memory leakage result corresponding to the set operation task based on the first memory information subset and the second memory information subset may be: acquiring the total execution time of a set operation task; determining the memory leakage rate based on the memory leakage amount and the total execution time; if the memory leakage rate is larger than or equal to a second set threshold value, setting that the memory leakage exists in the operation task; and if the memory leak rate is smaller than a second set threshold, setting that the memory leak does not exist in the operation task.

The total execution time length may be a preset execution time length, and is used for periodically executing the set operation task in the total execution time length. The memory leakage amount may be a memory leakage amount corresponding to the set operation task executed periodically within the total execution duration, and the memory leakage rate may be: memory leak amount/total length of execution time. The second set threshold may be any value, but this embodiment is not limited to this, and may be, for example, 5 million per hour, 10 million per hour, or the like. For example, if the total execution time is 24 hours, the memory leak amount is 100 megabytes, and the memory leak rate is: and 100 Mm/24 hours, the second set threshold value is 5 Mm per hour, and the memory leak rate is smaller than the second set threshold value, so that the memory leak of the operation task is set. If the total execution time is 1 hour, the memory leakage amount is 100 megabytes, and the memory leakage rate is as follows: and 100 Mm/1 hour, the second set threshold value is 5 Mm per hour, and the memory leak rate is greater than the second set threshold value, so that the memory leak of the operation task is set.

In this embodiment, whether the memory leak exists in the set operation task is determined by the memory leak rate, so that whether the memory leak exists in the set operation task can be further accurately detected, and the accuracy of detecting the memory leak is improved.

Optionally, after determining, based on the memory information set, a memory leak result corresponding to the set operation task, the method further includes: if the memory leakage exists in the set operation task, controlling the target equipment to periodically execute a plurality of subtasks respectively; reading the memory information of the target equipment after the execution of the subtask is finished, and obtaining a subtank memory information set; and determining a memory leakage result corresponding to the subtask based on the sub memory information set.

Specifically, when memory leakage exists in the set operation task, the target device is controlled to periodically execute a plurality of subtasks, the memory information of the target device is read every set time length in the periodic execution of the subtasks by the target device, a memory information set is obtained, and a memory leakage result corresponding to the subtasks is determined according to the memory information set. In this embodiment, a manner of periodically executing the subtask by the control target device is consistent with a manner of periodically executing the set operation task by the control target device in the above embodiment, a manner of obtaining the sub memory information set and a manner of determining the memory leakage result corresponding to the subtask based on the sub memory information set are consistent with a manner of reading the memory information of the target device after the execution of the set operation task is completed, a manner of obtaining the memory information set and a manner of determining the memory leakage result corresponding to the set operation task based on the memory information set in the above embodiment, and details are not described here.

In this embodiment, when there is memory leak in the set operation task, the target device is controlled to periodically execute a plurality of subtasks, respectively, the memory information of the target device after the execution of the subtasks is completed is read, a subtank information set is obtained, and a memory leak result corresponding to the subtask is determined based on the subtank information set, so that whether there is memory leak in each subtask in the set operation task can be more accurately detected, and the accuracy of detecting the memory leak can be further improved.
