[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] The serial numbers assigned to the components in this application, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning.

[0048] First of all, before specifically introducing the technical solutions of the disclosed embodiments of the present application, the background technology or technical evolution context on which the embodiments of the present application are based is introduced. With the development of computer technology, more and more applets have emerged. The applets include a logic engine and a view engine. The logic engine is a system that controls the business logic of the applets, and is mainly responsible for the execution of business modules and data processing in the applets; the view engine is a system for rendering the applets' pages, and is mainly responsible for page and function interactions, as well as view control of the built-in components of the applets. An Internet page is a global, dynamically interactive, cross-platform distributed graphic information system based on hypertext and the hypertext transfer protocol. An Internet page in a mini-program is an offline Internet page with local resources.

[0049] During the use of the mini program, the business party needs to open too many page stacks under a complex processing flow. Each page stack represents an Internet page. The opened pages always occupy the mini program system memory, which can easily lead to insufficient memory in the mini program system. After the mini program system memory exceeds the upper threshold, the system will start the default protection behavior and forcibly clean up the memory occupied by the open pages, which will cause the page to appear white and cannot be restored, causing the user to be unable to operate. In traditional technology, when designing mini programs, technicians forcibly set users to open a maximum of a preset number of pages, and new pages cannot be opened beyond the preset number. However, although the technical solutions in traditional technology can solve the problem that the page appears white and cannot be restored after the memory exceeds the upper threshold, when the number of opened pages exceeds the preset number, the new page still cannot be opened, affecting the user's continued operation. Normally, each page in the mini program occupies 30M of memory, the preset number is 10, and the 11th page cannot be opened. In this regard, the present application provides a memory management method.

[0050] The technical solution of the present application and how the technical solution of the present application solves the technical problem are described in detail below with specific embodiments.

[0051] The memory management method provided in this application can be applied to computer devices installed with various applets, and the computer devices can be, but are not limited to, smart phones, tablet computers, portable wearable devices, etc. The internal structure of the computer device can be as follows: Figure 1 As shown, the computer device includes a processor, a memory, a communication interface, a display screen and an input device connected to a system bus. Among them, the processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The communication interface of the computer device is used to communicate with an external terminal in a wired or wireless manner, and the wireless manner can be implemented through WIFI, a mobile cellular network, NFC (near field communication) or other technologies. When the computer program is executed by the processor, a memory management method is implemented. The display screen of the computer device can be a liquid crystal display screen or an electronic ink display screen, and the input device of the computer device can be a touch layer covered on the display screen, or a key, trackball or touchpad set on the computer device housing, or an external keyboard, touchpad or mouse, etc.

[0052] In one embodiment, Figure 2As shown, a memory management method is provided for managing the memory in the applet system. This embodiment is illustrated by applying the method to a computer device, that is, the computer device manages the memory in the applet. In this embodiment, the method includes the following steps:

[0053] Step 200: Get the number of pages in the open state.

[0054] The order of opening multiple pages in the mini program is that when the first page is opened, the user operates the components on the first page to open the second page, and the second page will cover the first page; the user operates the components on the second page to open the third page, and the third page will cover the first page. Multiple pages can be opened in the same way. If the user is currently on the third page and needs to view the second page, he needs to exit the third page to return to the second page.

[0055] During the running of the mini program, the computer device obtains the number of pages in the open state, that is, the total number of pages opened in sequence when the user uses the mini program.

[0056] In an optional embodiment, the computer device monitors the number of pages in the mini-program that are open in real time when monitoring the user launching the mini-program.

[0057] Step 210: determine a target memory release policy according to the number of pages, and release memory from the pages in the open state according to the target memory release policy.

[0058] After obtaining the number of pages in the applet that are open, the computer device determines the target memory release strategy to be used according to the number of pages in the applet that are open at this time. That is, the target memory release strategy is related to the number of pages in the applet that are open. The target memory release strategy can be pre-set by the technician and stored in the computer device.

[0059] After determining the target memory policy, the computer device uses the target memory release policy to release memory from the pages in the open state, that is, the memory occupied by the pages in the open state is released according to the memory release method specified in the target memory release policy. The memory released according to the target memory release policy can be the memory occupied by all the pages in the open state, or it can be the memory occupied by some of the pages in the open state. This embodiment does not limit this, as long as the released memory is enough to open a new page.

[0060] In an optional embodiment, a technician may pre-set a memory threshold value and store it in a computer device, and the memory threshold value indicates the maximum memory required to open a new page. The computer device may execute a target memory release policy to release memory from an open page according to the memory threshold value, that is, release memory of a memory threshold value size from an open page according to the target memory release policy.

[0061] In another optional embodiment, the computer device may detect the memory required for opening a new page, and execute a target memory release policy to release memory from the opened page according to the detected required memory.

[0062] Step 220: Open a new page based on the released memory.

[0063] After the computer device releases memory according to the target memory release policy, the applet in the computer device can open a new page in response to the user's opening operation based on the released memory, that is, use the released memory to open a new page.

[0064] The memory management method provided in the embodiment of the present application obtains the number of pages in an open state, determines a target memory release policy according to the number of pages, and releases memory from the pages in an open state according to the target memory release policy; and opens a new page based on the released memory. In this embodiment, memory is released from the pages in an open state by using a target memory release policy determined according to the number of pages, so that when the number of pages reaches an upper threshold, the released memory can be used to open a new page, thereby solving the problem that pages exceeding the upper threshold cannot be opened, thereby ensuring that the mini program can run normally and the user can continue to operate the mini program.

[0065] In one embodiment, an implementation method of determining a target memory release strategy according to the number of pages is provided, and the steps of the implementation method include:

[0066] The target memory release strategy is determined based on the number of pages and a preset number threshold.

[0067] The preset quantity threshold may be pre-set by a technician and stored in the computer device. The quantity threshold set by the technician may be one or more. In the case where the technician sets more than one quantity threshold, there may also be more than one corresponding memory release strategy.

[0068] After obtaining the number of pages of the applet that are currently open, the computer device compares the number of pages with a preset number threshold, and determines a target memory release strategy based on the comparison result.

[0069] When there is one preset number threshold, there is one corresponding memory release strategy. After obtaining the number of pages, the computer device determines whether the number of pages is greater than the preset number threshold; if it is determined that the threshold of the number of pages is greater than the preset number threshold, the corresponding memory release strategy is determined as the target memory release strategy.

[0070] When there are multiple preset quantity thresholds, there are multiple corresponding memory release strategies, that is, one preset quantity threshold corresponds to one memory release strategy. After obtaining the number of pages, the computer device compares the number of pages with the multiple preset quantity thresholds and determines a target memory release strategy from the multiple memory release strategies.

[0071] In this embodiment, the target memory release policy is determined by the number of pages and a preset number threshold. This method of determining the target memory release policy is quick and easy to implement, and can improve the efficiency of the memory management method, thereby improving the efficiency of opening new pages.

[0072] In one embodiment, the preset quantity threshold includes a preset first quantity threshold, a preset second quantity threshold and a preset third quantity threshold, the first quantity threshold is greater than the second quantity threshold, and the second quantity threshold is greater than the third quantity threshold. Figure 3 As shown, an implementation method of determining a target memory release strategy according to the number of pages and a preset number threshold is involved, and the steps of the implementation method include:

[0073] Step 300: If the number of pages reaches a preset first number threshold, determine that the target memory release policy is a first memory release policy.

[0074] After obtaining the number of pages, the computer device compares the number of pages with a preset first number threshold to determine whether the number of pages reaches the preset first number threshold. In other words, the computer device determines whether the number of pages is greater than the first number threshold and less than the second number threshold.

[0075] If the computer device determines that the number of pages is greater than the first number threshold and less than the second number threshold, the target memory release policy is determined to be the first memory release policy. The first memory release policy is the memory release policy corresponding to the first number threshold.

[0076] Step 310: If the number of pages reaches a preset second number threshold, determine that the target memory release policy is the second memory release policy.

[0077] After obtaining the number of pages, the computer device compares the number of pages with a preset second number threshold to determine whether the number of pages reaches the preset second number threshold. In other words, the computer device determines whether the number of pages is greater than the second number threshold and less than the third number threshold.

[0078] If the computer device determines that the number of pages is greater than the second number threshold and less than the third number threshold, the target memory release policy is determined to be the second memory release policy. The second memory release policy is the memory release policy corresponding to the second number threshold.

[0079] Step 320: If the number of pages reaches a preset third number threshold, determine that the target memory release policy is the third memory release policy.

[0080] After obtaining the number of pages, the computer device compares the number of pages with a preset third number threshold to determine whether the number of pages reaches the preset third number threshold. In other words, the computer device determines whether the number of pages is greater than the third number threshold.

[0081] If the computer device determines that the number of pages is greater than the third number threshold, the target memory release policy is determined to be the third memory release policy. The third memory release policy is the memory release policy corresponding to the third number threshold.

[0082] The memory released by the third memory release strategy is greater than the memory released by the second memory release strategy, and the memory released by the second memory release strategy is greater than the memory released by the first memory release strategy. As the number of pages increases, the memory release strategy used releases more memory.

[0083] In this embodiment, by comparing the number of pages with different preset number thresholds, the memory release policies corresponding to the different number thresholds are determined as target memory release policies, so that the target memory release policy can be determined quickly and accurately, thereby improving the efficiency of opening new pages.

[0084] In an optional embodiment, if the number of pages is less than a preset first number threshold, it means that the number of pages opened at this time has not reached the situation where memory needs to be released before a new page can be opened. In other words, if the unused memory in the applet is sufficient to open a new page, the new page is opened directly without releasing memory according to the determined target memory release policy.

[0085] In an optional embodiment, if the computer device determines that the number of pages is within a first number threshold range formed by a first number threshold and a second number threshold, then the target memory release policy is determined to be the first memory release policy; if the computer device determines that the number of pages is within a second number threshold range formed by a second number threshold and a third number threshold, then the target memory release policy is determined to be the second memory release policy; if the computer device determines that the number of pages is neither within the first number threshold range nor within the second number threshold range, and is greater than the first number threshold range, then the target memory release policy is determined to be the third memory release policy.

[0086] In one embodiment, the first memory release strategy includes: releasing the first memory corresponding to at least one page in the open state; the first memory includes at least one of the virtual tree, component tree and component data in the view engine memory of at least one page.

[0087] The memory corresponding to the applet includes view engine memory and logic engine memory. The view engine memory is used to represent the data required for page display and data for user interaction, and the logic engine memory is used to represent the data required for executing business modules.

[0088] The view engine memory includes real node tree, virtual tree, component tree and component data, etc. The real node tree refers to the various data that users see on the page, and the virtual tree is the structure corresponding to the real node tree. The virtual tree can reflect the layout of the page, but the components in the virtual tree cannot be operated; the component tree refers to the components in the page layout, and the component data refers to the status of each component in the page layout.

[0089] When a computer device releases memory according to a first memory release strategy, at least one of the virtual trees, component trees, and component data corresponding to any one of the pages in an open state is released; or at least one of the virtual trees, component trees, and component data corresponding to any multiple pages in an open state is released.

[0090] In this embodiment, when the number of pages is greater than the first number threshold and less than the second number threshold, at least one of the virtual tree, component tree and component data in the page in the open state is released. The memory released in this way is various data in the view engine, and the business interaction of the applet is all realized through the logic engine. At this time, releasing the memory in the view engine will not affect the normal operation of various functions in the logic engine. For example, the interface request, timer, event callback and other functions in the logic engine can be realized, and the released memory can be used to open a new page, thereby solving the problem that the page whose number exceeds the third number threshold cannot be opened, so that the user can continue to operate the applet. In addition, the various data in the released view engine are also saved in the logic engine, so that when the page whose memory is released is opened later, the corresponding data is directly obtained in the logic engine, which can improve the efficiency of opening the page, and there will be no white screen when the page is opened.

[0091] In an optional embodiment, if Figure 4 As shown, assuming that the first quantity threshold is 10 pages, and the memory occupied by each page is 30M. When the 11th page is opened, part of the data in the first two pages in the view engine memory is released (15M for each page). Figure 4 The memory in the dashed box is the released memory.

[0092] In one embodiment, the second memory release strategy includes: releasing the second memory corresponding to at least one page in the open state; the second memory includes all data in the view engine memory corresponding to the at least one page.

[0093] For the description of the view engine memory, please refer to the specific description in the above embodiment, which will not be repeated here.

[0094] When the computer device releases memory according to the second memory release strategy, it releases all data in the view engine memory corresponding to any one or more pages in the open state, that is, it releases the real node tree, virtual tree, component tree and component data corresponding to any one or more pages.

[0095] In this embodiment, when the number of pages is greater than the second number threshold and less than the third number threshold, the real node tree, virtual tree, component tree and component data in at least one of the pages in the open state are released. The memory released in this way is the data in the view engine, and the business interactions of the applet are all implemented through the logic engine. At this time, releasing the memory in the view engine will not affect the normal operation of various functions in the logic engine, such as interface requests, timers, event callbacks and other functions in the logic engine. In addition, the released memory can be used to open a new page, thereby solving the problem that the page whose number exceeds the second number threshold cannot be opened, so that the user can continue to operate the applet. In addition, the data in the released view engine is also saved in the logic engine, so that when the page that releases the memory is opened later, the corresponding data is directly obtained in the logic engine, which can improve the efficiency of opening the page.

[0096] In an optional embodiment, if Figure 5 As shown, assuming that the first quantity threshold is 15 pages, and the memory occupied by each page is 30M, all data in the view engine of the first page are released when the 16th page is opened. Figure 5 The memory in the dashed box is the released memory.

[0097] In one embodiment, the third memory release strategy includes: releasing the third memory corresponding to at least one page in the open state; the third memory includes data in the view engine memory and data in the logic engine memory corresponding to the at least one page.

[0098] For the description of the logic engine memory, please refer to the specific description in the above example, which will not be repeated here.

[0099] When the computer device releases memory according to the third memory release strategy, it releases the data in the view engine memory and logic engine memory corresponding to any one or more pages in the open state, that is, the view engine memory and logic engine memory in at least one page in the open state are released.

[0100] In this embodiment, when the number of pages is greater than the third number threshold, data in the view engine memory and data in the logic engine memory corresponding to at least one of the pages in the open state are released. In this way, the released memory can be used to open a new page, thereby solving the problem that the pages whose number exceeds the third number threshold cannot be opened, so that the user can continue to operate the mini program.

[0101] In an optional embodiment, if Figure 6 As shown, assuming that the first quantity threshold is 20 pages, and the memory occupied by each page is 30M, when the 21st page is opened, all data in the view engine of the first page and all data in the logic engine memory are released. Figure 6 The memory in the dashed box is the released memory.

[0102] In one embodiment, after the computer device releases memory from the page in the open state according to the target memory release policy, the memory management method further includes:

[0103] Add page identifiers to pages of freed memory.

[0104] The page identifier is used to indicate that the page is a page that has released memory data. After releasing the memory of a page, the computer device will directly add a page identifier to the page. The page identifier can be a label added to the name corresponding to the page, or a retrieval function can be set for the page, through which the data required to open the page can be obtained. This embodiment does not limit the form of the page identifier added to the page that has released memory, as long as its function can be achieved.

[0105] In this embodiment, after the memory of a page is released according to the target memory release policy, a page identifier will be added to the page. In this way, when the page is reopened later, it can be determined through the page identifier that the data corresponding to the page is released. When the released data is retained in the logic engine memory, it can be directly obtained in the logic engine, thereby improving the practicality and reliability of the memory management method.

[0106] In one embodiment, Figure 7 As shown, when the user needs to open the page before the current page, that is, exit the current page, or open a new page, the steps of the method further include:

[0107] Step 700: Detect whether there is a page identifier for the page to be opened.

[0108] The page to be opened can be a new page opened by the user, or can be a page returned by the user after exiting the current page. When the page to be opened needs to be opened, the computer device detects whether the page to be opened has a page identifier.

[0109] Step 710: If a page identifier exists, data information corresponding to the page to be opened is obtained from the logic engine memory, and the page to be opened is displayed according to the data information.

[0110] If the computer device determines through detection that there is a page identifier in the page to be opened, indicating that the page is a page that has released memory data, the computer device obtains data information corresponding to the page to be opened from the logic engine memory and displays the page to be opened according to the data information.

[0111] If the page with the page identifier releases memory according to the first memory release strategy, the computer device obtains the data information corresponding to the page to be opened from the logic engine memory; creates a new virtual tree and component tree according to the data information, and restores the mapping relationship between the created virtual tree and component tree and the real node tree to ensure that the page to be opened can respond normally.

[0112] If the page with the page identifier releases memory according to the second memory release policy, the computer device obtains the data information corresponding to the page to be opened from the logic engine memory; creates a new virtual tree, component tree and real node tree based on the data information to ensure that the page to be opened can respond normally.

[0113] In this embodiment, the computer device determines whether there is a page identifier for the page to be opened, and when it is determined that the page identifier exists for the page, it directly obtains the data information corresponding to the page from the logic engine memory, and displays the page to be opened according to the data information. This can improve the efficiency of opening the page to be opened, thereby improving the practicality of the memory management method.

[0114] In one embodiment, Figure 8 As shown, the method also includes:

[0115] Step 800: Detect whether there is a page identifier for the page to be opened.

[0116] The page to be opened can be a new page opened by the user, or can be a page returned by the user after exiting the current page. When the page to be opened needs to be opened, the computer device detects whether the page to be opened has a page identifier.

[0117] Step 810: If a page identifier exists, data information corresponding to the page to be opened is created, and the page to be opened is displayed according to the data information.

[0118] If the page with a page identifier releases memory according to the first memory release strategy, that is, the memory data such as the virtual tree, component tree and component data in the view engine are released, the computer will restore the data through the logic engine, and the unreleased pages of the real node tree memory can still be reused. The user needs to wait until the page is restored before responding normally.

[0119] If the page with a page identifier releases memory according to the second memory release strategy, that is, the memory data such as the virtual tree, real node tree, component tree and component data in the view engine are all released, then the computer restores the entire page through the data in the logic engine, and the user needs to wait until the page is restored before responding normally.

[0120] If the page with a page identifier releases memory according to the third memory release strategy, that is, the data in the view engine memory and the logic engine memory corresponding to the page are released, then the computer device needs to reload the page like opening a new page, create data information corresponding to the page to be opened, and ensure that the page to be opened can respond normally.

[0121] In an optional embodiment, the step of adding a page identifier to a page of released memory includes:

[0122] A page identifier is added to the page of the released memory according to the target memory release strategy corresponding to the page of the released memory. Different target memory release strategies are used, and different page identifiers are added.

[0123] In an optional embodiment, the steps of the memory management method further include:

[0124] If the page to be opened has a page identifier, a target memory release policy corresponding to the page identifier is determined; and the page to be opened is displayed according to the target memory release policy.

[0125] Different target memory release policies correspond to different page identifiers.
