Correspondingly, present example proposes a kind of file updating method, as in figure 2 it is shown, its handling process is such as Following:
Step 21, file updating device by the file in system according to setting regular partition as different classes of.
Step 22, by each file correspondence mappings respectively after classification to revising file directory, the first renewal literary composition Part catalogue and file directory of dispatching from the factory.
Amendment file directory, the first more new file directory and dispatch from the factory and possess layered relationship between file directory, The corresponding different operator precedence level of file between different stackings.
The embodiment of the present invention propose technical scheme in, file updating device by the file in system according to use File in system is layered by rule or operating right, maps with access limit with different carry orders Build base file system, it is possible to realize classifying according to upgrading processing flow process, improve the maintainability of system.And And, by the file declustering on the basis in system, it is possible to reach the effect of file multiplexing, multisystem environment.
Such as, the document classification in system, according to operating right, can be amendment file by file updating device (modified), first updates file (update), the file that dispatches from the factory (orig) three major types.
In being embodied as, file updating device on startup, can add and initialize before startup system Code, setup code is allocated according to initial configuration file, and Choose for user relation.Such as will / modified/root ,/update/root ,/orig/root, be mapped as/root.
In the technical scheme that the embodiment of the present invention proposes, having layer between different classifications must be related to, is entering Row is in now, and the file on upper strata can have precedence over the file of lower floor and present.Such as, by initial system file Being placed on the file directory layer that dispatches from the factory, the file of renewal is placed on the first more new file directory layer, and the superiors are amendment literary composition Part catalogue layer, file directory of dispatching from the factory layer and first more new file directory layer is for outermost layer catalogue (namely layer The catalogue that poststack shows) it is read-only, so all amendments to outermost layer catalogue all can be at amendment literary composition Part catalogue layer.
Step 23, it is determined whether have file to be updated, if it is judged that be yes, performs step 24, Otherwise end processes.
Step 24, determine need file is updated time, by the of file update step set in advance It is the second more new file directory that one more new file directory renames.
Step 25, backup the second more new file directory and by backup the second more new file directory rename into First more new file directory.
Backup the second more new file directory specifically can use following two ways:
First kind of way: by first more new directory the named second more new directory, the second renewal of duplicated naming Catalogue and will replicate after second more new directory the named first more new directory.
The second way: set up the file storage area of the entitled second more new directory, by first more row catalogue All files copy in the second more new directory.
Step 26, it is thus achieved that the file content of renewal.
Obtain the file content of the file that needs are updated, determine the store path that file content is corresponding, press This document content is stored according to store path.
In the technical scheme that the embodiment of the present invention proposes, as it is shown on figure 3, for application program For (appliciation, APP) developer, use the technical scheme that the embodiment of the present invention proposes, App Developer the file content of file updated will be needed to be committed to the corresponding mesh that file updating device provides Record.Then the technical scheme that the developer of App proposes according to the embodiment of the present invention, it would be desirable to app combination, Fill in correspondence configuration file, file updating device determine need file is updated time, it is thus achieved that need The file content of file to be updated, determines the store path that file content is corresponding, according to store path Storage this document content.Thus realize integrating the file content received.
In being embodied as, first, the bibliographic structure that the developer of App provides according to file updating device, carry Hand over file content (such as code, picture etc.), those file contents are defined as an assembly, join In file updating device.Wherein, component content can comprise code management system path, and system resource can Management attribute etc..The developer of App can define the information such as the title/version of self this assembly, can define Definition makes the hook script of AKU.
Secondly, file updating device, according to configuration template, selects the assembly needed to be combined, thus realizes Automatically building software kit and AKU, during structure, file updating device can call app and want to make by oneself The hook script of justice completes the customization operation of application program.Further, file updating device is permissible Take out the system resource allocation situation that will build, according to the resource information of each application/system component, right Configure than the virtual resource of existing device, carry out abstract optimization, generate the resource distribution that modules is corresponding Script.
Again, file updating device utilizes resource distribution script/configuration template to carry out resource optimization for application program, File is installed.App developer can be allowed without being concerned about the optimization of system level, reduce system hlerarchy soft The complexity that part is installed.And can upgrade just for one or more assemblies, accelerate the speed of upgrading Degree reduces the impact on system.In AKU can with the different processing method of self-defined each AKU with Upgrading flow process, processes also by hook script.
In the technical scheme that the embodiment of the present invention proposes, app developer is in submitting the file needing to update to File content, without considering how software kit makes, only need to be submitted to the literary composition of configuration by Rong Shi, app developer The corresponding catalogue that part updating device provides.The app combination that app developer will need, fills in the configuration of correspondence File, automatically can integrate app, generate corresponding product software bag and AKU.By traditional system choosing Select software to install, become selecting system in combination, file updating device the installation unifying maintenance management software is unloaded Current-carrying journey.
