Embodiment

Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail.Although shown exemplary embodiment of the present disclosure in accompanying drawing, yet should be appreciated that and can realize the disclosure and the embodiment that should do not set forth limits here with various forms.On the contrary, it is in order more thoroughly to understand the disclosure that these embodiment are provided, and can by the scope of the present disclosure complete convey to those skilled in the art.

With reference to Fig. 1, show the flow chart of steps of a kind of update method embodiment 1 of application program according to an embodiment of the invention, described method can comprise the steps:

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

In embodiments of the present invention, the first file and the second file can be the file generating in advance, directly extract; The first file and the second file can be also current generations.

For making those skilled in the art understand better the embodiment of the present invention, in this manual, a kind of example using browser as application program describes.

In a preferred embodiment of the present invention, described one or more the first files can be one or more the first files that All Files is generated according to the structure category packing of the application program of described first version;

In actual applications, for example, composing document due to an application program (browser) is all tens, even up to a hundred conventionally.If the application program of a version of upgrading need to configure upgrading to each composing document, can cause upgrading ten/complexity, so the All Files of application program (for example browser) must break into a compressed package or a plurality of compressed package according to bibliographic structure.These compressed packages are only all that file is packed, and do not use any compression algorithm, so that carry out incremental computations.

As a kind of preferred exemplary of the embodiment of the present invention, described one or more the first files can comprise first foundation component file and/or the first extension element file;

In specific implementation, described one or more the first files can generate in the following manner:

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

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

An application program can be comprised of a lot of files, and wherein major part is all a little expansion plugins and some other small routine.Infrastructure component can be for realizing the file of the foundation function of application program, for example in browser, play up function etc., extension element can be for realizing the file of the expansion function of application program, for example the gesture operation function in browser, search plug-in unit etc.

It should be noted that, different application is under different demands, foundation function and expansion function can be different, the embodiment of the present invention can specified application in arbitrarily file be infrastructure 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 structurized catalogue file after installing, and infrastructure component and extension element can have the storing directory of appointment, and this storing directory can be root directory, can be second-level directory etc.

In a preferred embodiment of the present invention, one or more the second files that described one or more the second files can generate according to structure category packing according to the application program of the second version for All Files;

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

In this example, the application program of first version can be the application program of redaction, the application program of the second version can be the application program of legacy version, and application program compares large-scale renewal, need to upgrade the application program of whole version.

It should be noted that, the structure category of the application program of the second version can be corresponding with the structure category of the application program of first version.

As a kind of preferred exemplary of the embodiment of the present invention, described one or more the second files can comprise the second infrastructure component file and/or the second extension element file;

In specific implementation, described one or more the second files can generate in the following manner:

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

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

It should be noted that, the application of the second infrastructure component file and the second extension element file is identical with the application of first foundation component file and the first extension element file substantially, relevant part can be with reference to the related description of first foundation component file and the first extension element file, and the embodiment of the present invention is not described in detail at this.

In addition, under the prerequisite allowing at client performance, the embodiment of the present invention can also be divided into a plurality of assemblies such as three, four according to function by application program and pack, and then calculates the data difference of new and old edition and makes difference update file, and the embodiment of the present invention is not limited this.

Step 102, generates the renewal differential file of described one or more the first file and corresponding one or more the second files;

Upgrade the file that differential file can generate for the data that the first file and the second file there are differences.

In a kind of preferred enforcement of the present invention, described step 102 can comprise following sub-step:

Sub-step S31, adopts difference algorithm Courgette to calculate the infrastructure component differential file of described first foundation component file and described the second infrastructure component file;

Sub-step S32, adopts difference algorithm Courgette to calculate the extension element differential file of described the first extension element file and described the second extension element file;

Difference algorithm Courgette is structured on an Open Source Code bsdiff and bspatch basis, can find wherein difference for the binary file for two different editions (legacy version and redaction) (Binary File), generates patch file; According to this patch file, add that the binary file of legacy version generates the binary file of redaction in addition.

It should be noted that, first foundation component file and the second infrastructure component file, and, in the first extension element file and the second extension element file, can comprise binary file, also can comprise nonbinary file.For binary file, difference algorithm Courgette can first carry out dis-assembling, and then adopts bsdiff to carry out the calculating of differential file.For nonbinary file, difference algorithm Courgette can directly adopt bsdiff to carry out the calculating of differential file.

For the application program after compiling, even if changed very little source code, also can cause out-of-proportion other variation of a large amount of binary level.If add several line codes, such as, the inspection of a scope prevents cache overflow, after all codes all can be moved to hold new instruction.Some instruction and datas are often the addresses of other instruction and data, so the code after compiling is internal reference everywhere.But before these internal pointer change, be only the change of several line codes of minority, and be a large amount of internal pointer, such as the main DLL(Dynamic Link of browser Library, dynamic link library) program of size, the quantity of internal pointer probably has 500,000.

Source code does not have the problems referred to above, because all element is-symbol of source code.In the process of compiling and link, function is to be converted (commite) stage below to become assigned address.

Difference algorithm Courgette can use an original resolver (disassembler) to find internal pointer.Resolver is divided into 3 parts program: the list of an internal pointer destination address; Other byte and an instruction (Instruction) sequence decide common byte and pointer by adjusting and interting to get back to original input.This can be called to " language of decomposition " (assemblylanguage), because can process these instructions and issue this byte sequence with a resolver, return to original file.

The part of non-pointer has probably accounted for 80% of original application program because do not mix any pointer, by comparison better effects if some, the size of difference bag and source code change over linear relationship.The simple language that the decomposes version updating bag more out that uses is probably little by 30% than original.

Difference algorithm Courgette introduces label and comes home address, and pointer can be controlled.These addresses are stored in array the inside, and pointer list can be replaced by the subscript list of array.These data are original symbol tables, the name of these symbols, or label is the array index of integer in fact.Utilize symbol table, how Expression and Application program has certain degree of freedom to make difference algorithm Courgette.By changing corresponding list index, make difference algorithm Courgette can mobile array address around.

Difference algorithm Courgette converts original assemblylanguage to program, then in the rank of assembly, compares difference:

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, by the address (asm_new_adjusted=adjust (asm_new, asm_old)) of mobile asm_new internal symbol table, makes minimizing of version updating file.Mate address in two symbol tables, guarantees that index has a lot of public word strings on their statistical attribute.According to code or Debugging message around, does not mate by any exploratory method the address of alignment.

The application program of old edition and the application program of new edition must be good executable files.If the application program of the application program of old edition and new edition can comprise several executable files, also can comprise the file of decomplier as JavaScript and PNG picture, will be more useful.For browser, the application program of old edition and the application program of new edition are a kind of history files, can comprise the file of all installation and operation needs.

Difference algorithm Courgette converts input to the form of another more effective scale-of-two difference, does difference compression, and from source document, obtained and played the output after patch by contrary conversion in transformed space.After conversion regime by difference algorithm Courgette, can obtain a less AKU.

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

For further reducing taking of network traffics, can compress packing to infrastructure component differential file and/or extension element differential file, version updating bag is specifically as follows the compressed package of 7z compressed format.

Sub-step S34, is condensed to renewal differential file by described version updating bag pressure.

For the ease of taking of issue and further minimizing network traffics, the version updating bag pressure that issue is shortened into renewal differential file, be specifically as follows CAB file, be convenient to client decompression processing at once simultaneously.

CAB is the compressed package form that Microsoft works out, and is usually used in the installation procedure of application program, and the utility routine Extract.exe that uses Windows to carry can decompress to it, and WinZip, WinRAR, WinMount etc. support this form.

Step 103, issues described renewal differential file; Described renewal differential file can comprise download address;

By upgrading the upload onto the server position of middle appointment of differential file, issue, externally netting gear has a download address.

Step 104, generating configuration file; Described configuration file can comprise the download address of version information and the described renewal differential file of described the second version;

Configuration file config.ini can have outside the version information and download address of indication the second version (legacy version), can also have for identifying the name information of configuration file, check information for security verification, MD5(Message Digest Algorithm for example, Message Digest Algorithm 5), version information of first version (redaction) etc., the embodiment of the present invention is not limited this.

Step 105, issues described configuration file.

The upload onto the server position of middle appointment of configuration file config.ini is issued, client can be upgraded by download configuration file config.ini.

It should be noted that, the application program of front latest edition can be one, but client likely can all can not upgraded after the version updating of each application program, therefore the application version of client can exist a plurality ofly, and the renewal differential file upgrading can be for a plurality of, and configuration file can be one, be that the application program that configuration file comprises legacy version (can be part, also can be for all) version information, and, the download address of corresponding updating file.Certainly, configuration file also can be for a plurality of, and configuration file only includes the version information of application program and the download address of corresponding updating file of a legacy version.

With reference to Fig. 2, show the flow chart of steps of a kind of update method embodiment 2 of application program according to an embodiment of the invention, described method can comprise the steps:

Step 201, obtains configuration file from server side; Described configuration file comprises the version information of the second version and upgrades the download address of differential file;

The application embodiment of the present invention, client (can be application program) can for example, default time (every mornings 6 point, on every Saturdays 6 etc.), and also can the interval default time period (for example every 6 hours, 8 hours etc.) is initiatively from server download configuration file.

Server also can be initiatively for example, default time (every mornings 6 point, on every Saturdays 6 etc.), or default time period of interval (for example every 6 hours, 8 hours etc.) is initiatively to client push configuration file.

Server can also initiatively gather version information after application program update from client, to this version information of client push, upgrades corresponding configuration file.Client, in order to guarantee user's the right of privacy and right to know, can gather the version information of the application program in this client after server is authorized.Further, whether the user that can first check this client has added appointment plan, if, confirm that this client user authorizes the version information collection of the application program of server, server can continue to carry out collecting flowchart, if the user of this client does not add executive plan, confirm that this client user does not authorize the version information collection of the application program of server end, server end cannot obtain the version information of the application program in this client.

Step 202, when the version information of client is the version information of described the second version, downloads described renewal differential file from described download address;

Client can check the information in configuration file config.ini item by item, when the version information of the version information of client and the second version in configuration file config.ini is identical, accesses corresponding download address down loading updating differential file from server.

Step 203, adopts preset one or more the 3rd files and described renewal differential file to generate updating file;

In a preferred embodiment of the present invention, described one or more the 3rd files can be one or more the first files that All Files is generated according to the structure category packing of the application program of described the second version.The updating file that the 3rd file can be that client is last to be stayed after upgrading, the file that can generate in advance for client, can also be the current generation of client.

As a kind of preferred exemplary of the embodiment of the present invention, described one or more the 3rd files can comprise the 3rd infrastructure component file and/or the 3rd extension element file;

In specific implementation, if the 3rd file is that client generates in advance or in current generation, described one or more the first file can generate in the following manner:

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

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

It should be noted that, the application of the 3rd infrastructure component file and the 3rd extension element file is identical with the application of first foundation component file and the first extension element file substantially, relevant part can be with reference to the related description of first foundation component file and the first extension element file, and the embodiment of the present invention is not described in detail at this.

In inventive embodiments, described updating file can comprise that infrastructure component upgrades bag and/or extension element is upgraded bag; Described updating file can comprise that infrastructure component upgrades bag and/or extension element is upgraded bag;

Described step 203 can comprise following sub-step:

Sub-step S41, upgrades differential file described in decompress(ion), obtains version updating bag;

When renewal differential file is CAB file, can adopt Extract.exe, WinZip, WinRAR or WinMount to its decompress(ion).

Sub-step S42, version updating bag described in decompress(ion), obtains infrastructure component differential file and/or extension element differential file;

When to the further decompress(ion) of version updating bag, can obtain differential file and/or extension element differential file.When version updating bag can be for the compressed package of 7z compressed format, can adopt corresponding decompression algorithm to carry out decompress(ion).

Sub-step S43, adopts difference algorithm Courgette that described the 3rd infrastructure component file and described infrastructure component differential file formation base assembly are upgraded to bag;

Sub-step S44, adopts difference algorithm Courgette that described the 3rd extension element file and described extension element differential file are generated to extension element renewal bag.

In specific implementation, can carry out the combination that infrastructure component upgrades bag and/or extension element renewal bag by following flow process.

Client:

receive?asm_diff

asm_old=disassemble(original)

asm_new_adjusted=bspatch(asm_old,asm_diff)

update=assemble(asm_new_adjusted)

At the infrastructure component that adopts difference algorithm Courgette to calculate, upgrading bag in fact can be for example, with the packaging file (first foundation component file) of the infrastructure component file of the application program of redaction identical, and extension element is upgraded bag in fact can be for example, with the packaging file (the first extension element file) of the extension element file of the application program of redaction identical.

For binary file, difference algorithm Courgette can adopt bsdiff to carry out the combination of differential file, then carries out the respective operations of dis-assembling.For nonbinary file, difference algorithm Courgette can directly adopt bsdiff to carry out the combination of differential file.

It should be noted that, combination operation due to difference algorithm Courgette in embodiment of the method 2, can be strict with the operation splitting of difference algorithm Courgette in embodiment of the method 1 contrary, relevant part can reference method embodiment 1 in the part explanation of operation splitting of difference algorithm Courgette, the embodiment of the present invention is not described in detail at this.

Step 203, carries out decompress(ion) to described updating file;

Updating file after decompress(ion) can be the application program of redaction.

Step 204, installs the updating file after decompress(ion).

In embodiments of the present invention, client can be upgraded infrastructure component bag and/or extension element and upgrade the renewal that position that bag is installed to appointment can complete application program.

It should be noted that, infrastructure component upgrades bag to client and/or extension element is upgraded after bag installing, and can comprise that infrastructure component upgrades bag and/or extension element, in order to next update, as the 3rd infrastructure component file and/or the 3rd extension element file.

With reference to Fig. 3, show the flow chart of steps of a kind of update method embodiment 3 of application program according to an embodiment of the invention, described method can comprise the steps:

Step 301, the renewal differential file of generation the first file and the second file; Wherein, the composing document of the application program that described the first file is first version, described the second file is the composing document of the application program of the second version;

In actual applications, the first file and the second file can be the different editions of same composing document.Particularly, this composing document can be executable file (binary file), can be also non-executable file (nonbinary file).

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

In this example, the application program of first version can be the application program of redaction, and the application program of the second version can be the application program of legacy version, and application program has been carried out the renewal of composing document, can only based on composing document, upgrade.

In a preferred embodiment of the present invention, described step 301 can comprise following sub-step:

Sub-step S51, adopts difference algorithm Courgette to calculate the data difference file of the first file and the second file;

It should be noted that, in the first file and the second file, can comprise binary file, also can comprise nonbinary file.For binary file, difference algorithm Courgette can first carry out dis-assembling, and then adopts bsdiff to carry out the calculating of differential file.For nonbinary file, difference algorithm Courgette can directly adopt bsdiff to carry out the calculating of differential file.

For single executable file, when upgrading, conventionally may all just revise wherein one or two line code, but this modification may cause this function all functions afterwards all to move backward fixing length.So when adopting difference algorithm Courgette computational data difference, can first dis-assembling, then only selection difference block calculating wherein.

Particularly, a binary file the inside, comprise code section (function, data), pointed to pointer list (the compiling link generation of these functions, how to have comprised the information such as mapping function), because these addresses are inner relative addresses, even if changed a little line code, after recompility, the address of function will change, and the pointer value of pointing to these functions has also all changed.Therefore,, even if changed a slight variable, also can cause very manifold modification.

The principle of Bsdiff is carried out dis-assembling to binary file exactly, said two parts are processed respectively above, for code section, in fact just similar with common text, change not too large, substantially accounted for 80% left and right of whole binary file of this part volume.Then dynamic pointer is partly carried out to some and upgrade processing, just substantially reached 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

When to the further decompress(ion) of version updating bag, can obtain data difference file.When version updating bag can be for the compressed package of 7z compressed format, can adopt corresponding decompression algorithm to carry out decompress(ion).

Sub-step S63, adopts difference algorithm Courgette by described the 3rd file and described data difference file generated updating file.

In specific implementation, can carry out by following flow process the combination of data the 3rd file and differential file renewal bag.

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)
