303b, in the case where the backup file and the difference are differed with file, by the difference with file more
New extremely, difference resource bag updated after identical with the backup file.
Specifically, the backup file copy in data file is a, replace the difference file in difference resource bag.This
Sample, with regard to the backup file in data file and the difference file identical probability in difference resource bag can be improved, and then also
Improve according to data file enter row format conversion after data mapping file matched with the difference resource bag of prototype version it is general
Rate, after by data mapping document upgrading to mobile device, just improve prototype version that mobile device uses with according to original
The probability of the difference bag matching of the difference resource bag generation of version.
It should be noted that in most cases, backup file is differed in simply backup file with difference with file
Certain several file it is different from certain several file in difference file.So and need not be with whole backup file copies simultaneously
Difference file is replaced, and only needs to be copied and replaced with the file differed in file with difference in backup file.
But it is different from which file in backup file using must be known by difference file before such a processing method.
304th, in the case of the backup file and the difference are with file identical, the difference resource bag is defined as
The difference resource bag of prototype version.
It should be noted that in the case of backup file and difference are with file identical, it is possible to will once compile and obtain
Difference resource bag be defined as the difference resource bag of prototype version, for making the difference that difference upgrading is used in subsequent process
Bag.
102nd, the difference resource bag of target version is obtained.
Specifically, developer is on the basis of the corresponding source code of prototype version, according to the requirement of upgrading, to source code
Modify and compile, obtain the difference resource bag of target version.
It should be noted that when obtaining the difference resource bag of target version, the data text of target version can also be determined
Whether the difference in the difference resource bag of backup file and target version in part identical with file, with ensure as far as possible with
Difference bag of the mobile device of target version upgrading after is upgraded successfully when upgrading.
103rd, difference bag is generated using the difference resource bag of the prototype version and the difference resource bag of the target version.
Specifically, the difference file and the difference of prototype version in the difference resource bag of target version is corresponding with file
File do difference one by one, obtain the partial document in difference bag, then obtain difference further according to the difference resource bag of target version
Remaining partial document in subpackage, ultimately generates the difference bag from prototype version to target version.
The embodiment of the present invention provides a kind of method for generating difference bag, the source code generation data file of compiling prototype version
With difference resource bag；Determine whether the backup file in data file is identical with file with the difference in difference resource bag；Two
In the case that person differs, the data file after the source code generation renewal of prototype version and the difference money after renewal are recompilated
Wrap in source；Or, difference is updated to, difference resource bag updated after identical with backup file with file；Data file is used
Data mapping text needed for the mobile device to be upgraded to the prototype version for generation, obtains the difference resource of target version
Bag, and difference resource bag and the difference resource bag generation difference bag of target version using the prototype version.For the first
Processing mode, it is necessary to need the file of progress difference when judging and making difference bag in difference resource bag (i.e. after compiling source code
Difference is with file) whether file (backing up file) corresponding with data file identical, right in the case where both differ
Source code recompilates data file and difference resource bag after being updated, is then made according to the data file after renewal
Data mapping file is upgraded to mobile device, and according to the difference resource bag after renewal and the difference resource bag of target version
Difference bag is generated, so, relative to prior art, backup file and difference resource in the data file of prototype version can be reduced
The probability that difference is differed with file in bag, then according to the data mapping file after the data file transition form of prototype version
Mobile device is upgraded into prototype version to generate with the difference resource bag and the difference resource bag of target version according to prototype version
The difference bag possibility that the match is successful increase, eventually reduce mobile device difference upgrading failure probability.For second
Processing mode, it is necessary to need the file of progress difference when judging and making difference bag in difference resource bag (i.e. after compiling source code
Difference is with file) whether file (backing up file) corresponding with data file identical, and, will in the case where both differ
Difference is updated to, difference resource bag updated after identical with backup file with file, so, it is ensured that difference file
It is identical with backup file, that is, difference resource bag and data file matches are ensure that, the number according to prototype version is further ensured
Mobile device is upgraded into prototype version with being provided according to the difference of prototype version according to the data mapping file after file format transformation
The difference bag matching generated with the difference resource bag of target version is wrapped in source, eventually reduces the general of mobile device difference upgrading failure
Rate.
Further, as shown in figure 4, " the difference resource bag for obtaining prototype version " of step 101 can also be by following
Step is realized：
401st, the source code generation data file and difference resource bag of compiling prototype version.
Specifically, referring to step 301, it will not be repeated here.
402nd, determine whether the backup file is identical with the difference file.
Specifically, step 402 can be according to the following two kinds implementation：
The first, the cryptographic Hash of the backup file and the Kazakhstan of the difference file are calculated according to hash algorithm respectively
Uncommon value；In the case of the cryptographic Hash of the backup file and the cryptographic Hash identical of the difference file, the backup is determined
File is identical with file with the difference；Differed in the cryptographic Hash of the backup file with the difference with the cryptographic Hash of file
In the case of, determine that the backup file is differed with the difference with file.
Specifically, by input value of the backup file as hash algorithm, generating a cryptographic Hash；And make difference with file
For the input value of identical hash algorithm, another cryptographic Hash is generated.Whether identical compare two cryptographic Hash.If two Kazakhstan
Uncommon value is identical, then shows that backup file is identical with difference file content；If two cryptographic Hash are differed, show standby
Part file is differed with difference with file content.
Second, the cryptographic Hash of each file is calculated in the backup file and described according to the hash algorithm respectively
The cryptographic Hash of each file in difference file；The cryptographic Hash of each file and the difference file in the backup file
In corresponding file cryptographic Hash identical in the case of, determine that the backup file is identical with the difference file；Described
In the case that the cryptographic Hash of each file is differed with the difference with the cryptographic Hash of corresponding file in file in backup file,
Determine that the backup file is differed with the difference with file.
Specifically, using each file in backup file as the input of hash algorithm, obtaining each in backup file
The cryptographic Hash of file；Using each file in difference file as the input of hash algorithm, obtain every in difference file
The cryptographic Hash of one file.Compare the Hash of the cryptographic Hash of a file and respective file in difference file in backup file successively
Whether value is identical, the cryptographic Hash of the cryptographic Hash of each file file corresponding with difference file all phase in backup file
With in the case of, it is determined that backup file is identical with file with difference；The cryptographic Hash of each file is used with difference in backup file
In file the cryptographic Hash of corresponding file at least one differ in the case of, it is determined that backup file and difference file not phase
Together.
It should be noted that the Hash in whether first method, or second method, all embodiments of the invention
Calculation can be MD (Message Digest Algorithm, informative abstract) 5 algorithms or can be MD2 algorithms or can be with
It is SHA (Secure Hash Algorithm (SHA), or can also be that other Hash of the prior art are calculated
Method, the present invention is without limitation.
Further, because in the cryptographic Hash of each file in All Files in calculating backup file, different files it
Between to calculate process and the result of cryptographic Hash be separate, then can be by different file progress Hash calculations in backup file
Concurrent process processing.Similarly, the concurrent process that difference can also be carried out into Hash calculation with different files in file is handled.
In the prior art, a kind of CUDA of current popular (Compute Unified Device Architecture, unification
Computing device framework) model.CUDA basic thought is exactly that pending task is divided into serial executable portion and held parallel
Row portion is respectively processed.CPU (Central Processing Unit, central processing unit) and figure in CUDA programming models
Shape processor (Graphic Processing Unit, GPU) cooperates.CPU sends Kernel (kernels to graphics processor
Function) call request, graphics processor carries out parallel computation according to the call requests of Kernel functions to parallel data.
Concurrency when calculating each file cryptographic Hash is being make use of, and after CUDA programming models, further, is such as being schemed
Shown in 5, " calculate each in the backup file respectively according to the hash algorithm in second of implementation of step 402
The cryptographic Hash of file and the difference are with the cryptographic Hash of each file in file " it can also specifically be realized by following steps：
501st, CPU sends the first Kernel call request to graphics processor, and graphics processor receives the first kernel letter
Number Kernel call request.
Wherein, the first Kernel is used to indicate the graphics processor according to the hash algorithm in the backup file
Each file carries out Hash calculation.
It should be noted that carrying the storage address of backup file, graphics processor root in the first Kernel call requests
Backup file can be obtained by carrying out lookup according to the address.
502nd, graphics processor calls backup file according to the first Kernel, and according to hash algorithm to the system
Each file carries out the cryptographic Hash that Hash calculation obtains each file in the system file in file.
