With continued reference to Fig. 3, Fig. 3 is one of the application scenarios of the generation method of the incremental update bag according to the present embodiment and showsIt is intended to.
In the application scenarios of Fig. 3, as shown in icon 301 in Fig. 3, electronic equipment obtains first the redaction of intended applicationInstallation kit and old version installation kit.
Then, as shown in icon 302 in Fig. 3, above-mentioned electronic equipment obtains four new edition intrinsic safety in redaction installation kitDress file：Two binary files " 1.png ", " 2.png " and two texts " 1.jsp ", " 2.jsp ", and as schemed in Fig. 3Shown in mark 303, two old versions installation file binary file " 1.png " in old version installation kit and text text are obtainedPart " 1.jsp ".
Then, for redaction installation kit relative to old version installation kit increase newly two files " 2.png " andTwo files that " 2.jsp " directly replicates two files and may be copied to are pacified as " 2.png " and " 2.jsp " and old versionThe differential file of old version installation file in dress bag, as shown in icon 304 in Fig. 3.
Then, two are adopted to binary file " 1.png " of the same name in redaction installation kit and in old version installation kitSystem difference algorithm generates the differential file between two binary files " 1.png " of the same name, as shown in icon 305 in Fig. 3.It is rightTwo texts " 1.jsp " of the same name are generated using text difference algorithm in redaction installation kit and in old version installation kitDifferential file between two texts " 1.jsp " of the same name, as shown in icon 306 in Fig. 3.
Finally, will be to four differential files：" 2.png " and " 2.jsp ", two binary files of the same name after duplicationThe differential file between differential file and two texts " 1.jsp " of the same name between " 1.png ", obtains after being compressedCompressed package as intended application incremental update bag corresponding with redaction installation kit and old version installation kit, in such as Fig. 3Shown in icon 307.
Redaction installation kit and old version that the method that above-described embodiment of the application is provided passes through acquisition intended applicationInstallation kit, then for each the redaction installation file in above-mentioned redaction installation kit, according to the redaction installation fileFile type generates the differential file of the redaction installation file and old version installation file in above-mentioned old version installation kit,Each differential file for being generated finally is compressed, incremental update of the resulting file bag as above-mentioned intended application will be compressedBag.During incremental update bag between the redaction installation kit and old version installation kit that generate intended application, according toThe difference of the file type of each redaction installation file takes different differential file generation methods in redaction installation kit, subtractsThe file size of incremental update bag is lacked, the time needed for client downloads incremental update bag and flow has been reduced then.
With further reference to Fig. 4, the flow process 400 of another embodiment of the generation method of incremental update bag is it illustrates.ShouldThe flow process 400 of the generation method of incremental update bag, comprises the following steps：
Step 401, obtains the redaction installation kit and old version installation kit of intended application.
In the present embodiment, in the embodiment shown in the concrete process of step 401 and Fig. 2 a step 201 concrete process baseThis is identical, will not be described here.
Step 402, for each the redaction installation file in redaction installation kit, determines the redaction installation fileFile type, if the file type of the redaction installation file is binary file, goes to step 403 ', if the redactionThe file type of installation file is text, goes to step 403.
Find after the comparative analysis to existing file difference comparison algorithm, existing difference algorithm is generating twoDuring differential file between binary file, the file size of the differential file for often generating is big with original binary fileLittle no too big difference, therefore, discomfort is combined into two binary files and generates differential files, on the contrary, generates the mistake of differential fileThe formation speed that journey causes incremental update bag is slower, and causes client after incremental update bag has been downloaded, and needs to payThe time of redaction installation file is synthesized according to old version installation file and differential file.And existing difference algorithm is being generatedDuring differential file between two texts, the size difference of the differential file size for often generating and original textIt is larger, it is suitably for two texts and generates differential file.
Therefore, in the present embodiment, the generation method operation of incremental update bag electronic equipment (such as Fig. 1 institutes thereonThe server for showing) the redaction installation file can be determined for each the redaction installation file in redaction installation kitFile type, above-mentioned file type can be text or binary file.Wherein, text is referred to dedicated for depositingThe file of the data of storage text character, the file in addition to text is binary file, for example, picture file, audio frequency textPart, video file, executable program file etc..If the file type of the redaction installation file is binary file, turnTo step 403 ', if the file type of the redaction installation file is text, go to step 403.
Step 403 ', the redaction installation file is replicated, and the redaction installation file for obtaining will be replicated as the new editionThe differential file of old version installation file in this installation file and old version installation kit.
In the present embodiment, above-mentioned electronic equipment can in step 402 determine the files classes of the redaction installation fileIn the case that type is binary file, differential file is generated because discomfort is combined into two binary files, therefore, above-mentioned electronics setsIt is standby directly to replicate the redaction installation file, and the redaction installation file for obtaining will be replicated as redaction installation textThe differential file of old version installation file in part and old version installation kit.
In the present embodiment, above-mentioned electronic equipment can also in step 403 determine and not exist in old version installation kitIn the case of the filename identical old version installation file of the redaction installation file, show the redaction installation fileIt is increased file with respect to old version installation kit, therefore, it can directly replicate the redaction installation file, and duplication is obtainedRedaction installation file as old version installation file in the redaction installation file and old version installation kit differenceFile.
In the present embodiment, above-mentioned electronic equipment can also in step 405 judge the file of generated differential fileSize is of the same name in the redaction installation file and old version installation kit more than in the case of default file size threshold value, showingThe differential file of file it is larger, be not suitable for that the differential file is added in incremental update bag, accordingly it is also possible to directly replicateThe redaction installation file, and the redaction installation file for obtaining will be replicated as the redaction installation file and old version peaceThe differential file of old version installation file in dress bag.
Step 403, determines in old version installation kit with the presence or absence of the filename identical with the redaction installation fileOld version installation file, if it does, step 404 is gone to, if it does not, going to step 403 '.
In this implementation, above-mentioned electronic equipment can in step 402 determine the file of the redaction installation fileIn the case that type is text, determine in old version installation kit with the presence or absence of the filename with the redaction installation fileIdentical old version installation file, if it does, step 404 is gone to, if it does not, going to step 403 '.
Step 404, generates the text with the redaction installation file in the redaction installation file and old version installation kitThe differential file of part name identical old version installation file, and by the differential file for being generated, text is installed as the redactionThe differential file of old version installation file in part and old version installation kit.
In this implementation, above-mentioned electronic equipment can determine in step 403 in old version installation kit exist withIn the case of the filename identical old version installation file of the redaction installation file, show the redaction installation file phaseIt is amended file to old version installation kit, therefore, it can generate the redaction installation file and old version installation kitIn differential file with the filename identical old version installation file of the redaction installation file, and by the difference for being generatedFile, as the differential file of old version installation file in the redaction installation file and old version installation kit.In practice,Various existing text difference method comparison instruments (for example, google-diff-match-patch) can be adopted, to the new editionWith the filename identical old version installation file of the redaction installation file in this installation file and old version installation kitThe amount of making the difference is calculated, and generates differential file.
Whether step 405, the file size for judging generated differential file is more than default file size threshold value, if greatlyIn going to step 403 ', if it is not greater, going to step 406.
In the present embodiment, above-mentioned electronic equipment can in step 404 generate the filename of the redaction installation fileAfter the differential file of identical old version installation file, judge the file size of generated differential file whether more than pre-If file size threshold value.
If using the differential file for being generated as old version peace in the redaction installation file and old version installationThe differential file of dress file is simultaneously added in incremental update bag, then client is needed to be generated during incremental updateDifferential file pay with down-off and time：Time and flow, duplication institute needed for the differential file that network transmission is generatedThe required time of the differential file of generation, by the file with the redaction installation file of the intended application installed in clientName identical old version installation file residual quantity was updated to the time needed for the redaction installation file.And if replicating the new editionThis installation file as old version installation file in the installation of the redaction installation file and old version differential file and addIn being added to incremental update bag, then client is during incremental update, it is only necessary to pay following for the redaction installation fileFlow and time：Time and flow needed for the network transmission redaction installation file, the institute for replicating the redaction installation fileThe time for needing, without paying the identical with the filename of the redaction installation file of the intended application that will be installed in clientOld version installation file residual quantity update to the time needed for the redaction installation file.Therefore, in order to reduce clientThe flow of incremental update and time, need to arrange default file size threshold value, if the file size of the differential file for being generatedDuring more than default file size threshold value, show that differential file itself is larger, in order to save client the time of incremental update is carried outAnd flow, full dose renewal can be carried out to the redaction installation file, therefore, it can go to step 403 '.If generatedThe file size of differential file is not more than default file size threshold value, shows that differential file is less, carries out to save clientThe time of incremental update and flow, can carry out incremental update to the redaction installation file, therefore, it can go to step 406.
As an example it is supposed that the file size of redaction installation file F1 is 1MB (Mega Byte, Mbytes), new editionThe file size of this installation file F1 and differential file F1 ' of old version installation file F1 is 900KB (Kilo Byte, K wordSection).
If updated using full dose, need for redaction installation file F1 (file size 1MB) to be transferred to client, it is requiredTransmission time is 5 seconds, and the time that replicating redaction installation file F1 needs is 0.5 second, then client needs to pay altogetherTime be 5.5 seconds.
If updated using residual quantity, need for differential file F1 ' (file size 900KB) to be transferred to client, required biographyThe defeated time is 4.5 seconds, and the time that replication difference file F1 ' needs is 0.5 second, by the old version installation file F1 root of clientIt it is 1 second the time required to updating to redaction installation file F1 according to differential file F1 ' residual quantity, then client needs what is paid altogetherTime is 6 seconds.
Although the file size of differential file F1 ' is less than the file size of redaction installation file F1, from clientFrom the point of view of the total time that needs are paid, the time needed for full dose updates is shorter.Accordingly, it would be desirable to file size threshold value is pre-set, andAccording to the size of differential file whether more than the default file size threshold value come determine whether the differential file that will be generated asThe differential file of old version installation file in the redaction installation file and old version installation kit.
In practice, can carry out after statistical analysis previously according to the reproduction speed of wideband condition and existing terminal deviceFile size threshold value is set.
Step 406, the differential file for being generated is defined as to go through in the redaction installation file and old version installation kitThe differential file of history version installation file.
In the present embodiment, above-mentioned electronic equipment can in step 405 judge that the file of generated differential file is bigIn the case of little no more than default file size threshold value, show that generated differential file is less, be adapted to do incremental update, thereforeThe differential file for being generated can be defined as the redaction installation file and text is installed with old version in old version installation kitThe differential file of part.
Step 407, compresses each differential file for being generated, and will compress increasing of the resulting file bag as intended applicationAmount updates bag.
In the present embodiment, the generation method operation of incremental update bag electronic equipment thereon can be each to what is generatedIndividual differential file is compressed, and the file bag obtained by compressing is used as the incremental update bag of intended application.
