The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although showing the disclosure in accompanying drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here Limited.Conversely, there is provided these embodiments are able to be best understood from the disclosure, and can be by the scope of the present disclosure Complete conveys to those skilled in the art.

Reference picture 1, shows a kind of step of the update method embodiment 1 of application program according to an embodiment of the invention Rapid flow chart, methods described may include steps of：

Step 101, obtains one or more first files of the application program of first version and answering for the second edition respectively With one or more second files of program；

In embodiments of the present invention, the first file and the second file can be the file for previously generating, and directly extract； First file and the second file can also be currently generated.

To make those skilled in the art more fully understand the embodiment of the present invention, in this manual, using browser as should Illustrated with a kind of example of program.

In one preferred embodiment of the invention, one or more of first files can be by All Files according to One or more first files of the structure category packing generation of the application program of the first version；

In actual applications, due to an application program（Such as browser）Composing document be generally all tens, very To up to a hundred.If the application program of a version of upgrading needs to configure each composing document upgrading, upgrading can be caused very Complexity, therefore application program（Such as browser）All Files must break into a compressed package or multiple according to bibliographic structure Compressed package.These compressed packages are all only that file is packed, and any compression algorithm are not used, in order to carry out incremental computations.

Used as a kind of preferred exemplary of the embodiment of the present invention, one or more of first files can include first foundation Component file and/or the first extension element file；

In implementing, one or more of first files can be generated in the following manner：

Sub-step S11, first foundation group is packaged as by the infrastructure component of the application program of first version according to structure category Part file；

Sub-step S12, the first expanded set is packaged as by the extension element of the application program of first version according to structure category Part file.

One application program can be made up of many files, and wherein most is all a little expansion plugins and some other Small routine.Infrastructure component can be the file of the foundation function of realizing application program, such as render function in browser Etc., extension element can be the file of the expansion function of realizing application program, such as the gesture operation work(in browser , plug-in unit etc. can be searched for.

It should be noted that different application is under different demands, foundation function and expansion function can be with Be it is different, the embodiment of the present invention can based on arbitrary file in specified application component or extension element, for example The gesture operation function of above-mentioned browser can be included into infrastructure component.

The structure category of application program can be the catalogue file of the structuring after installing, and infrastructure component and extension element can Can be second-level directory etc. so that with the storing directory specified, the storing directory can be root.

In one preferred embodiment of the invention, one or more of second files can be All Files according to the One or more second files that the application program of two versions is generated according to structure category packing；

Wherein, the version information of the first version can be higher than the version information of the second edition.

Then in this example, the application program of first version can be the application program of redaction, the application of the second edition Program can be the application program of legacy version, and application program is compared and updated, it is necessary to answer whole version on a large scale It is updated with program.

It should be noted that the structure mesh of the application program of the structure category of the application program of the second edition and first version Record can be corresponding.

Used as a kind of preferred exemplary of the embodiment of the present invention, one or more of second files can include the second basis Component file and/or the second extension element file；

In implementing, one or more of second files can be generated in the following manner：

Sub-step S21, the second base set is packaged as by the infrastructure component of the application program of the second edition according to structure category Part file；

Sub-step S22, the second expanded set is packaged as by the extension element of the application program of the second edition according to structure category Part file.

It should be noted that the application of the second infrastructure component file and the second extension element file and first foundation component text The application substantially identical of part and the first extension element file, related part is referred to first foundation component file and first The related description of extension element file, the embodiment of the present invention is not described in detail herein.

Additionally, on the premise of client performance is allowed, the embodiment of the present invention can also draw application program according to function Be divided into three, multiple components such as four packed, the data difference for then calculating new and old edition makes difference update file, this Inventive embodiments are not any limitation as to this.

Step 102, generates one or more of first files poor with the renewal of corresponding one or more the second files Different article part；

Update the file that differential file can be generated by the data that the first file and the second file have differences.

In one kind of the invention is preferable to carry out, the step 102 can include following sub-step：

Sub-step S31, the first foundation component file and second basis are calculated using difference algorithm Courgette The infrastructure component differential file of component file；

Sub-step S32, the first extension element file and second extension are calculated using difference algorithm Courgette The extension element differential file of component file；

Difference algorithm Courgette is built on the basis of Open Source Code a bsdiff and bspatch, be can be used for For two different editions（Legacy version and redaction）Binary file（Binary File）, to find and wherein distinguish, generation is mended Fourth file；The binary file of redaction is generated plus the binary file of legacy version according further to this patch file.

It should be noted that first foundation component file and the second infrastructure component file, and, the first extension element file With can include binary file in the second extension element file, it is also possible to including nonbinary file.For binary file, Difference algorithm Courgette can first carry out dis-assembling, then carry out the calculating of differential file using bsdiff again.For non-two Binary file, difference algorithm Courgette can directly carry out the calculating of differential file using bsdiff.

For the application program after compiling, even if changing the source code of very little, also result in out-of-proportion big The amount other change of binary level.If adding several line codes, such as, inspection for scope prevents cache overflow, behind institute Some codes can all be moved to accommodate new instruction.Some instruction and datas are often the address of other instruction and data, So the code after compiling is internal reference everywhere.But before the change of these internal pointers, only a small number of several rows The variation of code, and be substantial amounts of internal pointer, the main DLL of such as browser（Dynamic Link Library, dynamic link Storehouse）The program of size, the quantity of internal pointer probably has 500,000.

And source code does not have above mentioned problem then, because all of element of source code is symbolism.Compile and link During, function is to be converted (commite in the stage below）Into specified address.

Difference algorithm Courgette can find inside and refer to an original decomposer (disassembler) Pin.Program is divided into 3 parts by decomposer：One list of internal pointer destination address；Other bytes and an instruction (Instruction) sequence returns to original input by adjusting and interting determining common byte and pointer.Then can be with This will be referred to as " language of decomposition " (assemblylanguage) because can be processed using a decomposer these instruction and This byte sequence is issued to return to original file.

The part of non-pointer probably account for the 80% of original application program, because not mixing any pointer, by comparison Effect is better, and the change of the size and source code of difference bag is linear.It is simple to be compared using the language for decomposing The version updating bag for coming is probably smaller by 30% than original.

Difference algorithm Courgette introduces label to identify address so that pointer can be controlled.These addresses are stored in Array the inside, and pointer list can be replaced by the subscript list of array.This data is an original symbol table, these symbols Number name, or label is in fact the array index of integer.Using symbol table so that difference algorithm Courgette how table There is certain free degree up to application program.By changing corresponding list index so that difference algorithm Courgette can be moved Address around array.

Difference algorithm Courgette Program transformation into original assemblylanguage, then assembly's Difference is compared in rank：

Server：

asm_old=disassemble(original)

asm_new=disassemble(update)

asm_new_adjusted=adjust(asm_new,asm_old)

asm_diff=bsdiff(asm_old,asm_new_adjusted)

transmit asm_diff

Difference algorithm Courgette passes through the address of mobile asm_new internal symbol tables（asm_new_adjusted= adjust(asm_new,asm_old)）So that the minimum of version updating file.Address in two symbol tables is matching, Ensure that index list possesses many public word strings on their statistical attribute.According to the code or Debugging message of surrounding, The address of alignment does not use any exploratory method to be matched.

The application program of old edition and the application program of new edition must be a good executable files.If old edition should Several executable files can be included with the application program of program and new edition, it is also possible to which the file comprising decomplier is such as JavaScript and PNG pictures, it will more useful.For browser, the application program of old edition and the application journey of new edition Sequence is a kind of history file, can include the file that all installation and operations need.

Difference algorithm Courgette is converted into input the form of another more effective binary system difference, in conversion Differential Compression, and the output after opposite conversion has beaten patch come the acquisition from original document are done in space.By difference After the conversion regime of algorithm Courgette, a smaller AKU can be obtained.

Sub-step S33, by the infrastructure component differential file and/or the extension element differential file boil down to version more New bag；

It is being the further occupancy for reducing network traffics, can be to infrastructure component differential file and/or extension element difference File is compressed packing, and version updating bag is specifically as follows the compressed package of 7z compressed formats.

Sub-step S34, is renewal differential file by the version updating packet compression.

For the ease of issue and the further occupancy for reducing network traffics, the version updating packet compression to be issued into renewal Differential file, is specifically as follows CAB file, while being easy to the client can horse back decompression processing.

CAB is the compressed package form that Microsoft is worked out, and is usually used in the installation procedure of application program, using Windows certainly The utility program Extract.exe of band can be decompressed to it, and WinZip, WinRAR, WinMount etc. support this form.

Step 103, issues the renewal differential file；The renewal differential file can include download address；

The position specified during differential file is uploaded onto the server will be updated to be issued, there is external net one to be downloaded ground Location.

Step 104, generates configuration file；The configuration file can include the version information of the second edition and described Update the download address of differential file；

Configuration file config.ini can have the instruction second edition（Legacy version）Version information and download address it Outward, there can also be the name information for identifying configuration file, for the check information of security verification, such as MD5 （Message Digest Algorithm, Message Digest Algorithm 5）, first version（Redaction）Version information etc., The embodiment of the present invention is not any limitation as to this.

Step 105, issues the configuration file.

Issued the position specified during configuration file config.ini is uploaded onto the server so that client can be following Configuration file config.ini is carried to be updated.

It should be noted that the application program of preceding latest edition can be one, but client is possible without every Can be all updated after the version updating of secondary application program, therefore the application version of client there may be multiple, then enter The renewal differential file that row updates can be multiple, and configuration file can include legacy version for one, i.e. configuration file Application program（Can be part, or all）Version information, and, the download address of corresponding more new file.When So, configuration file can also be multiple, i.e., one configuration file only include a version information for the application program of legacy version with And the download address of corresponding more new file.

Reference picture 2, shows a kind of step of the update method embodiment 2 of application program according to an embodiment of the invention Rapid flow chart, methods described may include steps of：

Step 201, configuration file is obtained from server side；The version information of the configuration file including the second edition and more The download address of new differential file；

Server can also be actively in the default time（For example 6 points of every morning, on every Saturdays 6 points etc.）, or Every the default time period（Such as every 6 hours, 8 hours etc.）Actively to client push configuration file.

Server actively can also gather version information after application program update from client, should to client push Version information is updated corresponding configuration file.Client is obtained to ensure the right of privacy and right to know of user in server The version information of the application program in the client can be gathered after to mandate.It is possible to further first check the client Whether user adds specified plan, if it is, confirming version information of the client user to the application program of server Collection is authorized, and server can continue executing with collecting flowchart, if the user of the client does not add executive plan, Then confirm that version information collection of the client user not to the application program of server end is authorized, server end cannot Obtain the version information of the application program in the client.

Step 202, when the version information that the version information of client is the second edition, under the download address Carry the renewal differential file；

Client can item by item check the information in configuration file config.ini, when version information and the configuration of client When the version information of the second edition in file config.ini is identical, accesses corresponding download address and downloaded more from server New differential file.

Step 203, using the file of one or more preset 3rd and renewal differential file generation more new file；

In one preferred embodiment of the invention, one or more of 3rd files can be by All Files according to One or more first files of the structure category packing generation of the application program of the second edition.3rd file can be visitor Family end is last update after the more new file that leaves, the file that can be previously generated for client can also be that client is worked as Previous existence into.

Used as a kind of preferred exemplary of the embodiment of the present invention, one or more of 3rd files can include the 3rd basis Component file and/or the 3rd extension element file；

It is one if that the 3rd file is previously generated for client or be currently generated in implementing Or multiple first files can be generated in the following manner：

Sub-step S31, the 3rd base set is packaged as by the infrastructure component of the application program of the second edition according to structure category Part file；

Sub-step S32, the 3rd expanded set is packaged as by the extension element of the application program of the second edition according to structure category Part file.

It should be noted that the application of the 3rd infrastructure component file and the 3rd extension element file and first foundation component text The application substantially identical of part and the first extension element file, related part is referred to first foundation component file and first The related description of extension element file, the embodiment of the present invention is not described in detail herein.

In inventive embodiments, the more new file can include that infrastructure component updates bag and/or extension element updates bag； The more new file can include that infrastructure component updates bag and/or extension element updates bag；

Then the step 203 can include following sub-step：

Sub-step S41, decompresses the renewal differential file, obtains version updating bag；

When it is CAB file to update differential file, can using Extract.exe, WinZip, WinRAR or WinMount is decompressed to it.

Sub-step S42, decompresses the version updating bag, obtains infrastructure component differential file and/or extension element difference text Part；

Further decompressed when to version updating bag, differential file and/or extension element differential file can be obtained.Work as version When renewal bag can be the compressed package of 7z compressed formats, can be decompressed using corresponding decompression algorithm.

Sub-step S43 is poor by the 3rd infrastructure component file and the infrastructure component using difference algorithm Courgette Different file generated infrastructure component updates bag；

Reference picture 3, shows a kind of step of the update method embodiment 3 of application program according to an embodiment of the invention Rapid flow chart, methods described may include steps of：

The renewal differential file of step 301, the first file of generation and the second file；Wherein, first file is first The composing document of the application program of version, second file is the composing document of the application program of the second edition；

In actual applications, the first file and the second file can be the different editions of same composing document.Specifically, The composing document can be executable file（Binary file）, or non-executable file（Nonbinary file）.

In a kind of preferred exemplary of the embodiment of the present invention, the version information of the first version can be higher than described second The version information of version.

Then in this example, the application program of first version can be the application program of redaction, the application of the second edition Program can be the application program of legacy version, and application program has carried out the renewal of composing document, can be based only on composing document and enter Row updates.

In one preferred embodiment of the invention, the step 301 can include following sub-step：

Sub-step S51, the data difference file of the first file and the second file is calculated using difference algorithm Courgette；

It should be noted that binary file can be included in the first file and the second file, it is also possible to enter including non-two File processed.For binary file, difference algorithm Courgette can first carry out dis-assembling, then be carried out using bsdiff again The calculating of differential file.For nonbinary file, difference algorithm Courgette directly can carry out difference text using bsdiff The calculating of part.

For single executable file, generally wherein one or two line code, but this simply all may be have modified when updating Modification may but cause all of function after the function to be all moved rearwards by fixed length.So using difference algorithm When Courgette calculates data difference, can first dis-assembling, then only select difference block therein to calculate.

Specifically, inside a binary file, code section is contained（Function, data）, point to these functions Pointer list（Compiling link is produced, contain how the information such as mapping function）, because these addresses are internal relative addresses, Even if having changed a small line code, after recompility, the address of function will change, and point to the pointer value of these functions All change.Therefore, even if having changed a slight variable, very manifold modification is also resulted in.

The principle of Bsdiff is exactly to carry out dis-assembling to binary file, and two parts described above are located respectively Reason, it is in fact just similar with common text for code section, change not too large, this partial volume is substantially accounted for 80% or so of whole binary file is removed.Then some renewal treatment are carried out to dynamic pointer part, is just substantially achieved The target of patch installing.

For non-executable file, basic calculation process is as follows：

Server:

diff=bsdiff(original,update)

transmit diff

For executable file, basic calculation process is as follows：

server：

asm_old=disassemble(original)

asm_new=disassemble(update)

asm_new_adjusted=adjust(asm_new,asm_old)

asm_diff=bsdiff(asm_old,asm_new_adjusted)

transmit asm_diff

Sub-step S52, is that file updates bag by the data difference compressing file；

It is being the further occupancy for reducing network traffics, packing, version updating can be compressed to data differential file Bag is specifically as follows the compressed package of 7z compressed formats.

Sub-step S53, packet compression is updated to update differential file by the file.

For the ease of issue and the further occupancy for reducing network traffics, the file to be issued is updated packet compression into renewal Differential file, is specifically as follows CAB file, while being easy to the client can horse back decompression processing.

Step 302, issues the renewal differential file；The renewal differential file includes download address；

Step 303, generates configuration file；The configuration file includes the version information of the composing document and the renewal The download address of differential file；

Step 304, issues the configuration file.

Reference picture 4, shows a kind of step of the update method embodiment 4 of application program according to an embodiment of the invention Rapid flow chart, methods described may include steps of：

Step 401, configuration file is obtained from server side；The version information of the configuration file including composing document and more The download address of new differential file；

Step 402, when the version information of the 3rd preset file is the version information of the composing document, under described Set address downloads the renewal differential file；

Step 403, using the 3rd file and renewal differential file generation more new file；

In one preferred embodiment of the invention, the 3rd file can be corresponding same with renewal differential file Individual composing document.3rd file can be the more new file left after updating the client last time, can also be that client is worked as The preceding composing document for using.

In one preferred embodiment of the invention, the step 403 can include following sub-step：

Sub-step S61, decompresses the renewal differential file, obtains file and updates bag；

Sub-step S62, decompresses the file and updates bag, obtains data difference file；

Further decompressed when to version updating bag, data difference file can be obtained.When version updating bag can be pressed for 7z During the compressed package of contracting form, can be decompressed using corresponding decompression algorithm.

Sub-step S63, using difference algorithm Courgette by the 3rd file and the data difference file generated more New file.

In implementing, the combination of the file of data the 3rd and differential file renewal bag can be carried out by below scheme.

For non-executable file, basic calculation process is as follows：

Client:

receive diff

update=bspatch(original,diff)

For executable file, basic calculation process is as follows：

Client:

receive asm_diff

asm_old=disassemble(original)

asm_new_adjusted=bspatch(asm_old,asm_diff)

update=assemble(asm_new_adjusted)

Step 404, more new file replaces the 3rd file by described in.

Complete to update by the more new file for generating is replaced into the 3rd file that current application program is used.
