The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
The method of the embodiment of the application comprises the steps of creating a cache list file for storing a cache list in a cache space in advance, copying a file corresponding to the cache task into the cache space by obtaining the cache task, obtaining the file size of the file if the copying is successful, calculating the sum of the size of all cache files in the cache list and the size of the file, namely the size of occupied space in the cache space, cleaning the cache space if the sum of the size of all cache files and the size of the file is larger than a preset threshold value, timely determining information of the cache space through the cache list file without calling a file interface for determination, accurately determining the size of the occupied space in the cache space through the cache list, automatically triggering an automatic cleaning function according to the size of the occupied space so as to conveniently clear redundant data in the cache space in time and further ensure that sufficient usable space exists in the cache space, the file is convenient to cache at any time.
Specifically, the game is composed of various resources, the resources may be understood as a combination of data, which is a basic component element of the game, and the implementation of the game is controlled, for example, the resources may specifically refer to a game scene, a model, audio, video, text, texture, and the like, during the use of the game, all the various used resources may be exported to a system file in the form of a file, and the resources may be named with a globally unique identifier (name), for example, in the case of a naming representation form of the various resources shown in fig. 1, the various resources exist in the form of a file and have a uniquely corresponding file name, and the file corresponding to each resource included in the system file in fig. 1 may be divided into a road, a tree, and a car, and sub-files included in each file, such as a road01 and a car 101.
Specifically, the game resources may be loaded on a small game platform, and the characteristics of the small game platform in terms of resource management include: the bag body is limited, the small game platform is used for reducing the time for loading the game and accelerating the starting speed of the game, the limitation on the game bag body is strict, the bag body can comprise main resources of the game, and for example, the small game platform limits the size of a main bag to be not more than 4M; the system comprises file system interfaces, all the small game platforms provide a set of exclusive file system interfaces, developers can use the interfaces to manage files, including file addition, deletion, reading and writing, but the exclusive file system interfaces of each small game platform are different from one another, and the compatibility is poor; the temporary file directory is used for automatically downloading files corresponding to game resources into the temporary file directory by the small game platform if a downloading cache path is not specified when the resources are downloaded on the small game platform, the files stored in the temporary file directory only have read permission, and although the size of the temporary directory is not limited, the files in the temporary file directory can be automatically cleaned by the small game platform when the small game exits, so that the secondary loading of the resources is inconvenient; the small game platform provides 200M buffer space for each small game, and the buffer space is recycled by the small game platform only when the small game is removed by the player.
Specifically, the process of loading game resources by using a small game platform can be shown in fig. 2. It can be understood that, during the running of the game, the loading of the game resource comprises the following steps: s210, resource positioning, namely analyzing a source global Unique label value (ID) into a real path of a resource on a file system; s220, reading the resource file, and reading the file into a cache space according to the path analyzed in the S210; s230, deserializing and finding a dependency list, which is used for deserializing the resource information read into the cache space in the S220 into a resource object and finding a dependency resource uuid list of the resource; s240, waiting for the loading of the dependent resources, loading all the dependent resources according to the dependent resource uuid list, and waiting for the completion of the loading of the dependent resources; and S250, initializing the resources, wherein the resources are used for initializing the resources, and the initialized resources are complete available resources.
Specifically, the specific operation flow of reading the resource file in S220 includes: and acquiring a real path of the resource analyzed by the S210 on the file system, judging whether the resource is on the remote server or not according to the real path, if not, directly reading the local resource, otherwise, downloading the resource from the remote server to a local space, and reading the resource in the local space, wherein the local space can comprise a temporary file directory or a cache space.
The embodiment of the present application is described in an application scenario where a mini game platform loads game resources, and it can be understood that the mini game platform may be configured in a client terminal 31 or a server terminal 32 as shown in fig. 3, and specifically, the present embodiment is applicable to a situation where the client terminal 31 performs cache space management, and the method may be executed by a cache space management device, where the device may be implemented in a software and/or hardware manner, and the device may be configured in an electronic device, for example, a terminal, and specifically includes but is not limited to a smart phone, a palmtop computer, a tablet computer, a wearable device with a display screen, a desktop computer, a notebook computer, an all-in-one machine, a smart home device, and the like. Alternatively, the embodiment may be applicable to the case of performing cache space management in the server 32, and the method may be performed by a cache space management apparatus, which may be implemented in a software and/or hardware manner, and may be configured in an electronic device, such as a server.
Fig. 4 is a flowchart illustrating a method for managing a cache space according to an embodiment of the present disclosure, where a cache list file is created in a cache space in advance, and a cache list is stored in the cache list file, where the cache list includes a plurality of fields, and the plurality of fields include a size field of the cache file.
It can be understood that by creating a cachelist file in a cache space in advance, that is, creating a cache list file as a database of the cache space for recording information of each cache file in the cache space, the information may include an identification field, a last use time field, and a size field of each cache file, by reading the cache list file in the cache space, a cache list in a memory is obtained, by querying the cache list in the memory, information of each cache file in the cache space can be directly obtained, without calling a file system interface (readdir) to obtain information of the cache file in the cache space each time the cache file is queried, speed of querying information of the cache file can be increased, and loading time of a game is further reduced.
The cache space management method includes steps S410 to S440 shown in fig. 4:
s410, obtaining the cache task to be processed, and copying the file corresponding to the cache task to a cache space.
It can be understood that, in the game loading process, after the resource file is downloaded to the temporary file directory, a cache task corresponding to the resource file is generated in the memory, where the cache task indicates information of the resource file downloaded in the local space, and the cache task may be added to a cache queue of the memory, at this time, the cache task to be processed corresponds to information of any downloaded resource file in the cache queue, where the downloaded resource file may be referred to as a cache file after being stored in the cache space, and preferably, the cache queue may include file names of the downloaded resource files, such as file names corresponding to various resources of the game shown in fig. 1 when the resources exist in a file form.
It can be understood that in the process of game loading, game resource files can be directly downloaded to a temporary file object, various limitations in the downloading process are reduced, the positions of the files corresponding to the game resource files in a temporary file directory are found according to a caching task, and the files are copied to a caching space from the temporary file directory, wherein in a small game platform, a certain amount of caching space is allocated to each small game, and the caching space is used for caching all the files downloaded from a Content Distribution Network (CDN), so that when the files are loaded for the second time, the caching resources are directly read from the caching space, and the game loading time is reduced.
And S420, after the file corresponding to the caching task is copied successfully, inquiring the file size of the file.
Understandably, on the basis of the above S410, the file corresponding to the caching task is successfully copied from the temporary file directory into the caching space corresponding to the file, that is, after the file is completely copied from the temporary file directory into the caching space, the file size of the file is queried through the file system interface.
Illustratively, the mini game A allocates a cache space A in the mini game platform, and a file downloaded by the mini game A is copied into the cache space A from the temporary file directory, so that the file is directly read from the cache space A when the mini game A is loaded next time.
Optionally, after the file corresponding to the caching task fails to be copied, the caching space is cleared.
It can be understood that, on the basis of the above S410, if the file corresponding to the caching task fails to be copied, the copying failure may have the following two cases: the cache space has no unoccupied space or the unoccupied space is not enough to store the file or the file is not completely copied into the cache space in the copying process, and the situation that the game fails, such as a flash back situation, may occur, and at this time, the automatic cleaning of the cache space is directly triggered.
S430, inquiring the size field of the cache file in the cache list to obtain the sum of the sizes of all the cache files in the cache list.
Understandably, on the basis of the above S420, the size fields of all the cache files recorded in the cache list are queried, that is, the file sizes of all the cache files in the cache list are directly queried, and the sum of the file sizes of all the cache files is calculated, where the cache files are stored in the cache space, that is, the size of the occupied space in the cache space, that is, the total size of all the files in the cache space.
S440, if the sum of the sizes of all the cached files in the cache list and the sum of the file sizes of the files are larger than a preset threshold value, cleaning the cache space.
Understandably, on the basis of the above S430, if the sum of the sizes of all the cache files recorded in the cache list and the sum of the sizes of the files corresponding to the cache task determined in the above S420 are greater than the preset threshold, that is, the sum of the size of the occupied space in the cache space and the size of the file currently copied to the cache space is greater than the preset threshold, the automatic cleaning of the cache space is triggered, so that it is ensured that the cache space always has a free space for continuing to cache the files, wherein the preset threshold can be set according to the user' S requirements, so as to clean the cache space in time.
Understandably, the information of the cache file recorded in the cache list does not include the information of the cache file corresponding to the currently acquired cache task to be processed, and at this time, the cache file corresponding to the cache task is not stored in the cache space, so that the sum of the file size of the cache file corresponding to the current cache task and the size of the cache file recorded in the cache list needs to be counted, and thus it is determined that the cache space does not trigger the automatic cleaning function after the cache file corresponding to the cache task is stored in the cache space.
The method for managing the cache space provided by the embodiment of the disclosure includes creating a cache list file for storing a cache list in a cache space in advance, obtaining a cache task, copying a file corresponding to the cache task to the cache space, obtaining the file size of the file if the copying is successful, calculating the sum of the size of all cache files included in the cache list and the size of the file, namely the size of an occupied space in the cache space, if the sum of the size of all cache files and the size of the file is larger than a preset threshold, cleaning the cache space, determining information of the cache space in time through the cache list file without calling a file interface, determining the size of the occupied space in the cache space accurately through the cache list, automatically triggering an automatic cleaning function according to the size of the occupied space, so as to clean redundant data in the cache space in time, and further, sufficient usable space exists in the cache space, and the file is convenient to cache at any time.
On the basis of the foregoing embodiment, optionally, before querying the size field of the cache file in the cache list, the method further includes:
reading the content of a cache list file in a cache space to obtain a cache list; and initializing the cache list into the memory.
It can be understood that the content of the cache list file established in the cache space in advance is read to obtain the cache list in the memory, that is, the cache list obtained through the reading operation is stored in the memory, and the cache list file stores the information of each cache file in the current cache space, that is, the information of the file corresponding to the cache task is not included.
Correspondingly, the size field of the cache file in the cache list is inquired from the memory.
Understandably, after obtaining the cache list in the memory, directly querying the size field of each cache file in the cache list from the memory.
According to the cache space management method provided by the embodiment of the disclosure, the cache list in the memory is obtained by reading the cache list file created in advance in the cache space, the information of the cache file can be directly obtained by querying the cache list, a file system interface is not required to be called, the information obtaining time can be effectively reduced, and the information of the cache space can be conveniently known.
On the basis of the foregoing embodiment, fig. 5 is a schematic flowchart of a method for managing a cache space according to an embodiment of the present disclosure, and optionally, the multiple fields further include an identification field of the cache file; after querying the size field of the cached file in the cache list, the cache space management method further includes steps S510 to S520 shown in fig. 5:
s510, recording the identification of the file to an identification field of a cache file in the cache list, and recording the file size of the file to a size field of the cache file in the cache list to obtain an updated cache list.
It can be understood that after the size field of the cache file in the cache list is queried, the cache list is updated, the process of determining that the cache space triggers automatic cleaning can be accelerated, the cache list does not need to be updated, and whether the cache space needs to be automatically cleaned can be directly determined according to the sum of the file size of the file queried before and the size of the cache file in the cache list.
Understandably, recording the identification (file name/name) of the file corresponding to the caching task to be processed into the identification field of the caching file in the caching list, namely, newly adding the information of the file in the caching list in the memory, wherein the information comprises the identification field; and recording the file size of the file to be queried to a size field of a cache file in a cache list, that is, adding a size field corresponding to the file to the cache list in a memory, where information of the file (a file corresponding to a cache task to be processed) in the cache list includes an identification field and a size field, to obtain an updated cache list, where the cache list includes, for example, 10 pieces of information, each piece of information corresponds to a cache file stored in a cache space, and after a file corresponding to a cache task to be processed is stored in the cache space, the information of the file is also correspondingly added to the cache list, and at this time, the cache list to which the file information is added includes 11 pieces of information.
And S520, writing the updated cache list into a cache list file.
It can be understood that, on the basis of the above S510, the cache list file is updated in time after a certain time according to the updated cache list, where the cache list file may be understood as a subset of the real cache list in the memory, that is, the number of cache file information included in the cache list file may be less than or equal to the number of cache file information included in the cache list, and there may be a case that the cache list is updated, but the cache list file is not updated yet.
The method for managing the cache space disclosed by the embodiment of the invention can timely feed back the information of the cache file newly stored in the cache space by writing the identification field and the size field of the file corresponding to the cache task to be processed into the cache list in the memory, updating the cache list, regularly updating the cache list file in the cache space according to the cache list, thereby ensuring the accuracy of the information in the cache list file stored in the cache space and being convenient for quickly inquiring the information of the cache file in the subsequent game loading process.
On the basis of the foregoing embodiment, fig. 6 is a schematic flowchart of a method for managing a cache space according to an embodiment of the present disclosure, and optionally, the multiple fields further include a last usage time field of the cache file; the cleaning of the buffer space includes steps S610 to S630 shown in fig. 6:
s610, inquiring the last use time field of the cache files in the cache list to obtain the last use time of all the cache files in the cache list.
It can be understood that the queried cache list may be an updated cache list or an un-updated cache list, where the un-updated cache list does not include information of a file corresponding to the cache task to be processed, the queried cache list is the last usage time of the cache file in the cache list, the last usage time of the file corresponding to the cache task to be processed is the latest usage time just stored in the cache space, and the usage time interval is short and does not belong to the cache file to be cleaned.
S620, one or more cache files to be cleaned are determined based on the last use time of all the cache files.
Optionally, the cache files are sorted in the rebuffering list according to the last usage time of the cache files, and one or more cache files to be cleaned are determined.
It can be understood that after the game is updated in multiple versions, the cache space also has the files corresponding to the old version before updating after the game is updated, and the last use time of the files corresponding to the part of old version is earlier along with the starting and running of the game, so that the memory occupied by the cache space can be reduced to a certain extent by deleting the useless files corresponding to the part of old version; and sequencing the cache list according to the last using time to obtain one or more cache files to be cleaned, wherein the number of the plurality of cache files to be cleaned can be set to be one third of the number of the cache files in the cache space.
Illustratively, the cache list includes information of 30 cache files, each piece of information corresponds to 1 cache file, the information of the 30 cache files is sorted according to the last use time of each cache file, the information of the 30 cache files is sorted according to the time sequence from front to back, the number to be cleaned is set to 1/3 of 30 total numbers, that is, the number to be cleaned is 10, the last determined information of the cache file to be cleaned is the first 10 sorted information, and the cache file in the cache space is determined to be the cache file to be cleaned according to the identification field in each piece of information.
S630, deleting one or more cache files to be cleaned.
Optionally, deleting one or more cache files to be cleaned includes:
