In the present embodiment, for certain application, server side is stored with this using corresponding all versions, that is, storeThe software kit of all versions, such as V1 versions, V2 versions and each self-corresponding software kit of V3 versions.
Wherein, above-mentioned first software kit can be the software kit of the V1 versions or V2 versions in the example above.
In actual R＆D process, it is assumed that when being V2 versions by V1 edition upgradings, research staff is based on the mistake in upgradingWhich modification Cheng Zhongqi has carried out and corresponding upgrading modification record has been generated to obtain V2 versions to the software kit of V1 versions, shouldWhich record the contents such as the file in the software kit having to V1 versions, parameter to be modified in upgrading modification record, Yi JixinThe contents such as which file, parameter are increased.
What wherein, can record in an indexed fashion all to the content in V1 version software bags in the upgrading modification recordIt is modified, the index can be that storage is indexed, function identification index etc..
What deserves to be explained is, when in illustrating as described above, an application has multiple versions, i.e., after V3 versions are generated, itsAbove there are two legacy versions, the two legacy versions all may be used by different users, therefore, should in order to meet all usesThe different upgrade requirements of user, when a redaction is generated, need to generate each for each legacy version beforeCorresponding upgrading modification file.
With above-mentioned as an example it is assumed that when by V1 edition upgradings to V2, generating the first upgrading corresponding with V1 versionsModification record, when by V2 edition upgradings to V3 versions, generate it is corresponding with V2 versions second upgrading modification record, then thisWhen, upgrading modification record of the V1 versions for V3 versions is it is considered that repaiied by the first upgrading modification record and the second upgradingChange record to constitute.
S102, extracts the content changed from the first software kit according to upgrading modification record.
The content changed is stored in the second software kit to obtain the 3rd software kit by S103, and the second software kit is to be upgradedTo the software kit of version.
S104, carries out difference processing to the second software kit and the 3rd software kit, to generate for from the first software packet upgradeTo the difference bag of the second software kit.
Assume the software kit that the first software kit is V2 versions, software kit of second software kit for V3 versions, in order to generate V2Difference bag needed for edition upgrading to V3 versions, in the present embodiment, first according to the corresponding upgrading modification record of V2 versions, from theCorresponding content, that is, content when researching and developing to the first software kit actual modification are extracted in one software kit.Secondly, can be by secondSoftware kit copies a copy, will extract and is stored in the copy software kit by modification content, obtains the 3rd software kit.MostAfterwards, comparing instrument bsdiff using binary system carries out difference processing to the second software kit and the 3rd software kit, with generate for fromThe difference bag of the first software packet upgrade to the second software kit.
In the present embodiment, for, for all versions that certain is applied, when server issues latest edition, needing to be based onDifference bag of the legacy version before said process generation is all relative to the latest edition, to meet different upgrade requirements.
With it is above-mentioned for example, currently issued two versions of V1 and V2, when needing to issue V3 versions, serverNeed to generate following difference bag：
Difference bag of the V1 edition upgradings to V3 versions；
Difference bag of the V2 edition upgradings to V3 versions.
In the present embodiment, when the upgraded version relative to legacy version is made, forming record has to which legacy version all doneThe upgradings modification files of a little modifications, so as to generate corresponding first software kit of legacy version corresponding with version is upgraded to secondDuring difference bag between software kit, the content changed is extracted first according to upgrading modification record from the first software kit, itThe content changed is stored in into the second software kit to obtain the 3rd software kit afterwards, now between the second software kit and the 3rd software kitFile only to be upgraded has differences, and is used for by carrying out difference processing to the second software kit and the 3rd software kit and just can generateFrom the difference bag of the first software packet upgrade to the second software kit.As the software for arriving to be upgraded is only included in the difference bag of the generationVersion relative to upgrading before old software version content that material change occurs only include file to be upgraded, will be free from the timeStamp file, so as to effectively reduce the size of difference bag, saves the memory space of server, reduces the flow for needing to expend.

In addition, after step S104, can also comprise the steps：
S202, the upgrade request that receiving terminal apparatus send, upgrade request include the version number of legacy version.
In practical application, when server side issues the redaction of certain application, can set to the terminal for being provided with the applicationPreparation send upgrading reminder message, if user response is when the upgrading reminder message triggers upgrading, terminal unit can be to serviceDevice sends upgrade request, the referred to as version number of the application installed in including present terminal equipment in the upgrade request, old editionThis version number.
The mode of the triggering upgrade request is only for example, and in practical application, such as can also be that user is not based on above-mentioned literLevel reminder message and actively trigger upgrade request.
S203, determines the version number to version to be upgraded according to the version number of legacy version.
In practical application, alternatively, server can combine the current terminal unit correspondence based on certain escalation policyThe version number of legacy version determine its version number to version to be upgraded.Such as, the escalation policy can only be upgraded to than currentWith regard to the higher leveled version of version, or latest edition.
Alternatively, certain version can also be carried in the above-mentioned upgrading reminder message that server is sent to terminal unitVersion number, the direct version comprising the version number and legacy version extracted from the upgrading reminder message in above-mentioned upgrade requestThis number, now, server directly knows the terminal unit is wanted from which edition upgrading to which version from upgrade request.
S204, obtains difference bag corresponding with the version number of legacy version and the version number to version to be upgraded.
As the method for having been based on embodiment illustrated in fig. 1 in advance generates the difference bag, above-mentioned two can be based onIndividual version number's inquiry obtains corresponding difference bag.
S205, difference bag is sent to terminal unit, so that terminal unit is risen to the first software kit according to difference bagLevel.
In the present embodiment, before difference bag generation is carried out, based on redaction software kit size come determine whether needWant difference bag, it is to avoid calculating that difference bag is caused etc. is also generated in the case where being not suitable for upgrading using difference packet mode and processes moneyThe waste in source.

S301, the upgrade request that receiving terminal apparatus send, upgrade request include the version number of legacy version and user's markKnow.
In the present embodiment, except the version extra of the legacy version of certain application program being currently installed in the upgrade request,ID can also be further included, the ID can be register account number of the user when the application program is registered.
S302, determines the upgrading step-length of terminal unit according to ID, according to upgrading step-length and the version number of legacy versionDetermine the version number to version to be upgraded.
In the present embodiment, the effect of the ID is primarily directed to different user carries out the system of differentiation upgrading authorityIt is fixed.For example, server can count acquisition use frequent degree of each user to the application program, for usage degreeThan more frequently user, which can be allowed directly to be upgraded to latest edition, and for usage degree less frequently user, such asWhich is only allowed to be upgraded to than the higher leveled version of currently used version.Specifically, frequent degree such as can be by monitoring userWith the business of total natural law, application opening times from the self installation application program determine that the determination mode is only for example, not withThis is limited.
Furthermore it is possible to delimiting in advance, several frequent degrees are interval, each frequent degree is interval corresponding to a kind of upgrading step-length,For for current terminal unit, the corresponding use frequent degree of the user is determined based on its ID, it is frequent according to thisThe interval determination upgrading step-length that degree is located at, so that it is determined that the version number to version to be upgraded is current legacy version number+upgradingStep-length, such as current legacy version is V1, and step-length is 2, it is determined that the version for arriving to be upgraded is V3.
In the present embodiment, use frequent degree of the user to upgrade applications needed for which is determined based on ID, withBased on the version being scalable to using frequent degree determination, it is achieved thereby that the differentiation upgrading control to different user, improvesThe motility of software release upgrade.
