Therefore, the software updating efficiency can be improved.
The following are detailed below. The numbers in the following examples are not intended to limit the order of preference of the examples.
In this embodiment, a software updating method is provided, as shown in fig. 1b, a specific flow of the software updating method may be as follows:
110. modification records of a plurality of files of the target software are obtained.
The target software may be a series of computer data and instruction sets organized according to a specific order, may be system software, or may be application software, where the application software may include game software, instant messaging software, and the like.
The plurality of files of the target software may include all files required for installation and operation of the target software. For example, taking game software as an example, a plurality of files of the game software may be divided into file types, where the file types may include, but are not limited to, art resource types, script types, and other file types, and the art resource types include art resource index subtypes and art resource subtypes; the plurality of files may include, but are not limited to, files corresponding to script types, files corresponding to art asset types, and other types of files. The files of art resource types may include files of art resource subtypes (such as game virtual character resource files, map resource files, user interface map files, and the like), files of art resource index subtypes (such as metadata of art resources, retrieval), and the like; other types of files may be files under a target directory, which may include, but is not limited to, a user interface directory (UI), a game avatar directory (Char), a pre-fabricated directory (Prefab), a virtual scenes directory (works), a routing grid directory (navigator), an audio directory (soundbs), a game configuration directory (GameConfig), a font directory (Fonts), a still picture directory (UIImage). It is understood that the file type of the file may also be related to a directory, for example, the Script type may correspond to a Script directory, and the art resource type may correspond to a warehouse (repo) directory, which includes sub-directories of virtual models, animations, effects, skins, bones, materials, maps, and the like.
The modification record may be information when the content of the file changes, and may include, but is not limited to, modification time and modification times; wherein the modification time may be a standard time when the file is modified. In some embodiments, the number of modifications may be statistically derived from the modification time.
The version control system records the modification records of the files each time a plurality of files of the target software are modified. In some embodiments, the version control system may obtain modification records of a plurality of files of the target software within a preset time period; the preset time period can be set by self according to the actual application condition, for example, the preset time period is set according to the frequency of software updating, and the higher the frequency of software updating, the higher the preset time period can be correspondingly shortened, for example, the preset time period can be half a year, two months, and the like. In some embodiments, the version control system may obtain all of the modification records for multiple files of the target software.
120. And determining the update frequency of the file according to the modification record of the file, wherein the update frequency represents the probability of the file being modified.
Wherein the update frequency can be divided into different levels. In some embodiments, the update frequency may include a first level, a second level, a third level, a fourth level and a fifth level, and the first level to the fifth level may indicate that the probability of the file being modified decreases in sequence, that is, the update frequency decreases in sequence. It can be understood that each level may be divided into a plurality of small levels, N may be used to represent the update frequency, and the value of N may be any integer, such as 5 or 6; for example, a first level may be represented as N levels, a third level may be represented as N/2+1 to N-1 levels, a second level may be represented as N/2 levels, a fourth level may be represented as 2 to N/2+1 levels, and a fifth level may be represented as 1 level; a larger value indicates a higher probability that the file is modified, i.e., more frequently updated. In some embodiments, the division of the update frequency may be determined according to the type of software, for example, the update frequency of the game software may be divided into more levels, and the instant messenger software may be divided into relatively less levels.
For software updating, part of files in the compressed package are updated frequently, and some files are not updated basically, so that the update frequency of the files can be determined according to the modification records of the files, and the probability that the files are possibly modified is obtained.
In some embodiments, the type of the file may be determined, and then the update frequency of the file may be determined according to the modification record of the file and the type of the file.
Determining the update frequency of the file according to the modification record of the file and the type of the file may include, but is not limited to: when the type of the file is the art resource index subtype, the update frequency of the file is determined to be a first level. And when the type of the file is the script type or the art resource subtype, determining the update frequency of the file according to the modification record of the file. For other types of files, the directory where the file is located can be determined; determining the directory grade corresponding to the file according to the directory where the file is located, wherein the directory grade can be divided into M grades; determining the update frequency of other types of files according to the modification records of the files; the update frequency of the other types of files is weighted based on the directory rank corresponding to the file to obtain the weighted update frequency of the file, for example, the directory rank and the update frequency of the file may be superimposed.
The specific implementation of determining the update frequency of the file according to the modification record of the file is not limited. In some embodiments, the standard time difference and the degree of temporal aggregation may be determined from the modification time. The standard time difference represents a time difference relationship between the modification time of the file and the current time, and the standard time difference can be calculated by adopting the following formula:
Figure BDA0003206382050000081
where n represents the number of modifications, t represents the current time, and the current time may be the time of acquiring the modification record.
The time aggregation degree represents the aggregation degree of the modification time of the file, and the time aggregation degree can be calculated by adopting the following formula:
Figure BDA0003206382050000082
wherein
Figure BDA0003206382050000083
Wherein x isiIndicates the modification time when the ith file is modified, and mu indicates the modification time of the fileAverage value of time.
And when the modification times are not less than the preset modification times and the standard time difference is not greater than the preset time difference threshold, determining the update frequency of the file as a first level.
And when the modification times are not less than the preset modification times and the standard time difference is greater than the preset time difference threshold value, determining the update frequency of the file as a second level.
And when the time aggregation degree is within the preset time aggregation degree range, determining the update frequency of the file as a third grade.
When the modification times are smaller than the preset modification times, determining the update frequency of the file according to the standard time difference and a preset time difference threshold; if the corresponding time difference threshold value range is set according to the preset time difference threshold value; when the standard time difference of the file is out of the time difference threshold range and the standard time difference is larger than the maximum value of the time difference threshold range, determining the update frequency of the file as a fourth grade; when the standard time difference of the file is within the range of the time difference threshold value, determining the update frequency of the file as a second grade; and when the standard time difference of the file is out of the time difference threshold range and the standard time difference is smaller than the minimum value of the time difference threshold range, determining the update frequency of the file as a third grade. Therefore, the update frequency of the file can be determined by the modification records of the file and combining experience and statistical methods, so that the probability that the file is possibly modified in the future is obtained, and the method conforms to the mode of software update.
For example, taking game software as an example, for a script type file, the update frequency of the file is determined according to the modification record of the file.
For files of art asset type: 1) and determining the update frequency of the file according to the modification record of the file for the common virtual game role and the map resource file. 2) repository is a metafile of resources (a file of art resource index type), and the update frequency of resource repository is determined to be N level. 3) Files in the local directory are mainly UI map files after map combination, and the UI map files are files which are updated relatively frequently, so that the re-distribution of maps is very easily caused by changed resources, and the update frequency of the files can be independently determined according to the modification records.
For files under the target directory (other types): 1) files under the UI, Char and Prefab directories are frequently updated files, and the directory level is determined to be M level. 2) Files under the Worlds, Navigate, and SoundBanks directories are next-to-frequently updated files, with the directory level determined to be M-1. 3) The frequency of updating files in other directories such as GameConfig, Fonts, UIImage and the like is low, and the directory grade is determined to be M-2 grade. And determining the update frequency of the files under different directory levels according to the modification records of the files, and superposing the directory levels to the update frequency of the files to obtain the final update frequency of the files.
In some embodiments, for a newly added file when a software update was last performed, when the newly added file is a hot update file or __ init __. py file or the like, the update frequency of the newly added file is determined to be a fifth level. And determining the updating frequency of other newly added files as a second grade.
In some embodiments, the update frequency of the file may be determined based only on the modified record of the file.
In some embodiments, the update frequency of the files in each directory may be determined individually according to the directory corresponding to the target software as a unit, or may be determined according to the modification record of the files.
130. And compressing the file according to the update frequency of the file to obtain a compressed package of the target software.
The compressed package of the target software can comprise a plurality of compressed files, or can be a large compressed file obtained by secondarily compressing a plurality of compressed files; the compression format of the compressed file is not limited, and may be RAR, ZIP, and the like. The compressed package of the target software may also be referred to as a full patch or full patch of the target software; which in certain cases may also be referred to as the target software's installation package.
Compressing the file according to the update frequency of the file may include, but is not limited to, the following steps:
s1: sorting the files according to the update frequency of the files to obtain sorted files; the files can be sorted from high to low according to the update frequency, and the files can also be sorted from low to high according to the update frequency.
S2: and compressing the sequenced files to obtain a compressed package of the target software. In some embodiments, the compressed file size threshold may be determined based on the network environment; for example, in a relatively stable platform such as windows, the compressed file size threshold may be 10M; other platforms where the network is unstable, the compressed file size threshold may be 4M, and so on. The size threshold of the compressed file is determined according to different network environments, and the flexibility is high.
And compressing the sorted files into a plurality of compressed files based on the size threshold of the compressed files, thereby obtaining a compressed package of the target software. In some embodiments, the compressed files may be numbered, and the higher the update frequency of the file corresponding to the compressed file is, the larger the number is; and the number of each compressed file may be unique.
In some embodiments, the directories corresponding to the files may be used as a unit, and the files in each directory are independently sorted according to the update frequency of the files. And then compressing the files sequenced in each directory to obtain a compressed package of the target software. In some embodiments, when compressing the sorted files corresponding to the file types, if the remaining files in each directory are not enough to be compressed into a compressed file with a compressed file size threshold, the files in multiple directories may be compressed into one compressed file.
In some embodiments, the file types of the files may be used as units, and the files corresponding to the file types are independently sorted according to the update frequency of the files. And then compressing the sorted files corresponding to the file types to obtain a compressed package of the target software.
In some embodiments, after the version control system obtains the compressed package of the target software, the compressed package may be uploaded to a content distribution network. If the client corresponding to the user has installed the target software, the client can download a compressed package of the target software from the content distribution network (at this time, the compressed package is equivalent to a patch package), and update the target software; if the client corresponding to the user does not install the target software, the compressed package of the target software (at this time, the compressed package is equivalent to the installation package) can be downloaded and installed.
140. And acquiring a plurality of update files corresponding to the target software.
The update files may include, but are not limited to, modified files (modified files) and newly added files. In some embodiments, the update file may be uploaded to the version control system by a developer, so as to obtain a plurality of update files corresponding to the target software.
In some embodiments, file information of the update file may also be obtained; the file information may be an update file List (List) that stores file identifications (e.g., file names, file numbers, etc.) of update files, and the like.
150. And updating the compressed package of the target software based on the update file so as to update the target software by using the updated compressed package.
In some embodiments, when a compressed file corresponding to an update file exists in a compressed package of target software, the compressed file corresponding to the update file is updated based on the update file, so as to obtain an updated compressed file. If the update file is a modified target file, the compressed file corresponding to the target file is a target compressed file, and the target compressed file is any compressed file in the compressed package of the target software; the target compressed file can be decompressed to obtain a target file set, the target file set comprises the original target file, the modified target file is adopted to replace the original target file, and then the target file set is compressed again to obtain an updated compressed file.
And when the compressed package of the target software does not have the compressed file corresponding to the update file, generating a new compressed file according to the update file. In some embodiments, the updated file is a new added file, and the compressed file compressed from the new added file may be numbered again based on the number of the previous compressed file.
And uploading the updated compressed file and the new compressed file so that the client updates the target software based on the updated compressed file and the new compressed file. In some embodiments, the updated compressed file and the new compressed file may also be collectively referred to as a delta patch or delta patch, and the versioning system uploads the delta patch to the content distribution network. Only the compressed file with the modified file is decompressed and replaced, so that the time for decompressing and recompressing can be reduced; and the sizes of the files uploaded to the content distribution network and downloaded to the client can be controlled in a smaller range, and the uploading and downloading speeds are improved.
In some embodiments, when the compressed file corresponding to the update file is updated based on the update file, file information of the compressed file corresponding to the update file may also be obtained; the file information of the compressed file may be a file list that may store an identification of the file in the compressed file, and the like.
Generating an update guide file based on the file information of the compressed file corresponding to the update file and the file information of the update file; the update boot file may store the number of the compressed file and the file under the compressed file corresponding to the number.
Uploading the update guide file so that the client downloads the updated compressed file and the new compressed file according to the update guide file; the version control system can upload the update boot file to the content distribution network, after the client starts the target software, the update program of the software can acquire the update boot file, then download the delta patch according to the update boot file, and update the target software based on the delta patch.
In some embodiments, the versioning system may also upload the delta patch to a content distribution network that updates a previously stored compressed package of the target software; after the client starts the target software, the update program of the software can acquire the update guide file, then download the updated compressed package from the content distribution network according to the update guide file, and update the target software based on the updated compressed package.
In some embodiments, file compression is performed under each directory, and files that need to be modified can be limited to within a single directory, thereby further reducing the size of the delta patch.
Therefore, the method can obtain the modification records of the files of the target software, and then determine the update frequency of the files by combining experience and statistical methods, namely obtaining the probability that the files are possibly modified in the future; then, according to the update frequency of the files, compressing the files of the target software by taking the directory as a unit, and compressing the files with higher update frequency together; therefore, when the file is modified, only a few compressed files can be updated, so that the time for decompressing the file and then recompressing the file can be reduced; and when the target software is updated, less compressed files can be uploaded to the content distribution network, and the client can download less compressed files, so that the uploading and downloading speed can be improved. Therefore, the software updating efficiency can be improved.

For files under the target directory (other types): 1) files under the UI, Char and Prefab directories are frequently updated files, and the directory level is determined to be M level. 2) Files under the Worlds, Navigate, and SoundBanks directories are next-to-frequently updated files, with the directory level determined to be M-1. 3) The frequency of updating files in other directories such as GameConfig, Fonts, UIImage and the like is low, and the directory grade is determined to be M-2 grade. And determining the update frequency of the files under different directory levels according to the modification records of the files, and superposing the directory levels to the update frequency of the files to obtain the final update frequency of the files. Therefore, the update frequency of the file is determined by the modification record of the file of the game software and combining experience and statistical methods, so that the probability that the file is possibly modified in the future is obtained, the update mode of the game software is met, and the accuracy of the update frequency is higher.
In some embodiments, determining the update frequency of the file from the modification record of the file comprises:

ii. The predetermined time concentration range is (S)t1,St2) When S ist1≤modStd≤St2And if the modification time distribution of the file is uniform, determining the update frequency of the file as N/2+ 1-N-1 level.
iii when n is<mtIf the modification time occurs earlier in mod Dis > DtI.e. modDis is significantly larger than Dt(ii) a Determining the update frequency of the file to be 2-N/2 +1 level; if the modification time occurs in the middle mod Dis ≈ Dt(ii) a Determining the update frequency of the file as N/2 level; if the modification time occurs at a later stage mod Dis > DtI.e. modDis is significantly smaller than Dt(ii) a The update frequency of the file is determined to be in the order of N/2+1 to N-1.
In some embodiments, for the newly added file when the software update was performed last time, when the newly added file is a hot update file and __ init __. py file, etc., the update frequency of the newly added file is determined to be level 1. And other newly added files determine the updating frequency to be N/2 level.
In some embodiments, the probability of future recovery of deleted files is low, and thus deletion may be largely disregarded.
In some implementations, the update frequency of script type, art resource type, and other types of files and their subclasses is normalized, and a mapping table between the normalized update frequency and the file is obtained. And sorting the files according to the update frequency from low to high to obtain a set of files which are arranged according to the probability that the files are modified from low to high.
230. And compressing the file according to the update frequency of the file to obtain a compressed package of the game software.
The sorted files are compressed by compression software to obtain a plurality of compressed files (also referred to as big files), that is, compressed packages of game software.
And setting a compressed file size threshold during compression, wherein if the compressed file exceeds 4M, a compressed file with a different number needs to be newly established, and for a platform with relatively stable network such as windows, the compressed file size threshold of the compressed file can be properly set to be larger, for example, 10M. The compressed package of the game software as shown in FIG. 2b may be generated based on the update frequency and the compressed file size threshold. The size threshold of the compressed file is determined according to different network environments, and the flexibility is high.
After the version control system obtains the compressed package of game software, the compressed package may be uploaded to a content distribution network. The client can download the compressed package of game software from the content distribution network and update the game software.
240. And acquiring a plurality of update files corresponding to the game software.
The version control system compares the compressed package of the game software to obtain a set of update files and an update file list of the update files.
250. The compressed package of the game software is updated based on the update file so that the game software is updated with the updated compressed package.
Inquiring a compressed file corresponding to the update file in a compressed package of the game software, decompressing the target compressed file if the file in the target compressed file is modified, deleting the file corresponding to the update file, and then merging the rest files into a set of the update file; and updating the file list in the target compressed file to the file list of the updated file to obtain an updated guide file.
And for the newly added files (the compressed packages of the game software do not have corresponding compressed files), merging the newly added files at the tail of the set of the updated files.
And re-compressing the set of updated files according to the size threshold of the compressed file to obtain the incremental patch. The number of the compressed file may be incremented and the number unique as shown in fig. 2 c.
The version control system uploads the delta patch and the updated boot file to the content distribution network. After the client starts the game software, the update program of the software can acquire the update boot file, then download the delta patch according to the update boot file, and update the game software based on the delta patch. Only the modified compressed file is decompressed and replaced, the file uploaded to the content distribution network and downloaded to the client can be controlled in a smaller range, and the uploading and downloading speed is improved.
Therefore, the method can acquire the modification records of the files of the game software, and then determine the update frequency of the files by combining experience and statistical methods, namely, the probability that the files are possibly modified in the future is obtained; then, according to the update frequency of the files, the files of the game software are compressed by taking the directory as a unit, and the files with higher update frequency can be compressed together; therefore, when the file is modified, only a few compressed files can be updated, so that the time for decompressing the file and then recompressing the file can be reduced; and when the game software is updated, less compressed files can be uploaded to the content distribution network, and the client can download less compressed files, so that the uploading and downloading speed can be improved.
