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 shows It 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 application Installation 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 kit Dress file：Two binary files " 1.png ", " 2.png " and two texts " 1.jsp ", " 2.jsp ", and as schemed in Fig. 3 Shown in mark 303, two old versions installation file binary file " 1.png " in old version installation kit and text text are obtained Part " 1.jsp ".
Then, for redaction installation kit relative to old version installation kit increase newly two files " 2.png " and Two files that " 2.jsp " directly replicates two files and may be copied to are pacified as " 2.png " and " 2.jsp " and old version The 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 kit System 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 right Two texts " 1.jsp " of the same name are generated using text difference algorithm in redaction installation kit and in old version installation kit Differential 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 duplication The differential file between differential file and two texts " 1.jsp " of the same name between " 1.png ", obtains after being compressed Compressed package as intended application incremental update bag corresponding with redaction installation kit and old version installation kit, in such as Fig. 3 Shown 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 application Installation kit, then for each the redaction installation file in above-mentioned redaction installation kit, according to the redaction installation file File 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 compressed Bag.During incremental update bag between the redaction installation kit and old version installation kit that generate intended application, according to The difference of the file type of each redaction installation file takes different differential file generation methods in redaction installation kit, subtracts The 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.Should The 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 base This is identical, will not be described here.
Step 402, for each the redaction installation file in redaction installation kit, determines the redaction installation file File type, if the file type of the redaction installation file is binary file, goes to step 403 ', if the redaction The 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 two During differential file between binary file, the file size of the differential file for often generating is big with original binary file Little no too big difference, therefore, discomfort is combined into two binary files and generates differential files, on the contrary, generates the mistake of differential file The formation speed that journey causes incremental update bag is slower, and causes client after incremental update bag has been downloaded, and needs to pay The time of redaction installation file is synthesized according to old version installation file and differential file.And existing difference algorithm is being generated During differential file between two texts, the size difference of the differential file size for often generating and original text It 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 thereon The server for showing) the redaction installation file can be determined for each the redaction installation file in redaction installation kit File type, above-mentioned file type can be text or binary file.Wherein, text is referred to dedicated for depositing The file of the data of storage text character, the file in addition to text is binary file, for example, picture file, audio frequency text Part, video file, executable program file etc..If the file type of the redaction installation file is binary file, turn To 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 edition The 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 file In the case that type is binary file, differential file is generated because discomfort is combined into two binary files, therefore, above-mentioned electronics sets It is standby directly to replicate the redaction installation file, and the redaction installation file for obtaining will be replicated as redaction installation text The 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 kit In the case of the filename identical old version installation file of the redaction installation file, show the redaction installation file It is increased file with respect to old version installation kit, therefore, it can directly replicate the redaction installation file, and duplication is obtained Redaction installation file as old version installation file in the redaction installation file and old version installation kit difference File.
In the present embodiment, above-mentioned electronic equipment can also in step 405 judge the file of generated differential file Size 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, showing The 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 replicate The redaction installation file, and the redaction installation file for obtaining will be replicated as the redaction installation file and old version peace The 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 file Old 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 file In the case that type is text, determine in old version installation kit with the presence or absence of the filename with the redaction installation file Identical 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 kit The differential file of part name identical old version installation file, and by the differential file for being generated, text is installed as the redaction The 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 with In the case of the filename identical old version installation file of the redaction installation file, show the redaction installation file phase It is amended file to old version installation kit, therefore, it can generate the redaction installation file and old version installation kit In differential file with the filename identical old version installation file of the redaction installation file, and by the difference for being generated File, 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 edition With the filename identical old version installation file of the redaction installation file in this installation file and old version installation kit The 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 greatly In 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 file After 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 installation The differential file of dress file is simultaneously added in incremental update bag, then client is needed to be generated during incremental update Differential file pay with down-off and time：Time and flow, duplication institute needed for the differential file that network transmission is generated The required time of the differential file of generation, by the file with the redaction installation file of the intended application installed in client Name identical old version installation file residual quantity was updated to the time needed for the redaction installation file.And if replicating the new edition This installation file as old version installation file in the installation of the redaction installation file and old version differential file and add In being added to incremental update bag, then client is during incremental update, it is only necessary to pay following for the redaction installation file Flow and time：Time and flow needed for the network transmission redaction installation file, the institute for replicating the redaction installation file The time for needing, without paying the identical with the filename of the redaction installation file of the intended application that will be installed in client Old version installation file residual quantity update to the time needed for the redaction installation file.Therefore, in order to reduce client The flow of incremental update and time, need to arrange default file size threshold value, if the file size of the differential file for being generated During 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 out And flow, full dose renewal can be carried out to the redaction installation file, therefore, it can go to step 403 '.If generated The file size of differential file is not more than default file size threshold value, shows that differential file is less, carries out to save client The 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 edition The file size of this installation file F1 and differential file F1 ' of old version installation file F1 is 900KB (Kilo Byte, K word Section).
If updated using full dose, need for redaction installation file F1 (file size 1MB) to be transferred to client, it is required Transmission time is 5 seconds, and the time that replicating redaction installation file F1 needs is 0.5 second, then client needs to pay altogether Time be 5.5 seconds.
If updated using residual quantity, need for differential file F1 ' (file size 900KB) to be transferred to client, required biography The 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 client It 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 altogether Time is 6 seconds.
Although the file size of differential file F1 ' is less than the file size of redaction installation file F1, from client From 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, and According 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 as The 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 device File 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 kit The 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 big In 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, therefore The differential file for being generated can be defined as the redaction installation file and text is installed with old version in old version installation kit The differential file of part.
Step 407, compresses each differential file for being generated, and will compress increasing of the resulting file bag as intended application Amount updates bag.
In the present embodiment, the generation method operation of incremental update bag electronic equipment thereon can be each to what is generated Individual differential file is compressed, and the file bag obtained by compressing is used as the incremental update bag of intended application.
Figure 4, it is seen that compared with the corresponding embodiments of Fig. 2 a, the generation side of the incremental update bag in the present embodiment The step of flow process 400 of method has had more the file size of the differential file to being generated and has judged.Thus, the present embodiment description Scheme can be of the same name during text and the redaction installation file are installed with old version going through in redaction installation file The file size of the differential file of history version installation file does incremental update in the case of being not more than default file size threshold value, instead It, does full dose renewal, so as to reduce the time that client carries out needed for incremental update to a greater extent.
