Embodiment
After the PDA program upgrade, if upgrade unsuccessfully, method provided by the invention can back up legacy version, and it is kept under the AKU catalogue, when PDA is restarted, regards the legacy version under the AKU catalogue as redaction and installs, thereby roll back to legacy version.
Specific embodiments of the present invention is described in detail below in conjunction with accompanying drawing and embodiment.
Please refer to Fig. 1, the process flow diagram for PDA of the present invention downloads AKU can comprise the following steps:
Step 101:PDA receives the username and password of user's input, logs in PDA;
Step 102: detect on gateway whether have AKU,, if do not exist, start the operating system, flow process finishes, and, if there is AKU, enters step 103;
Step 103: by the AKU of preserving on gateway configuration Archive sit judgement gateway be ZIP format compression bag bag (in this article, referred to as the ZIP bag) or the CAB bag, if ZIP bag, the ZIP bag is downloaded in PDA AKU catalogue and saves as the ZIP form, if the CAB bag, download to the CAB bag in PDA AKU catalogue and save as the CAB form;
Due to CAB bag take up room larger, so PDA to download CAB bag time of highest version longer, when unstable networks, the situation of interrupting also easily appears downloading.
Preferably, the present invention adopts the AKU of ZIP bag as the PDA program.Adopt the ZIP bag can save storage space, solve simultaneously the problem of interrupting of downloading.But consider and the compatibility of the current use version of PDA program, can keep simultaneously the function that the CAB bag is upgraded.That is to say, the present invention supports the upgrading of ZIP bag and CAB bag dual mode.When the PDA program need to be upgraded, ZIP bag or CAB bag were kept in gateway.Be the form that flows because PDA downloads AKU,, in order to judge that the AKU on gateway is ZIP bag or CAB bag, need to increase the judgement to the AKU type in the gateway configuration file.For example: the packets of information purse rope in the gateway configuration file shut the AKU version information (for example:＜Version〉WC-3.1.1.09＜/Version) and the AKU filename (for example:＜FileName〉updatefiles/FZI60/Patch-WC-3.1.1.09.zip＜/FileName), wherein the suffix of AKU filename is the AKU type, therefore, judgement AKU type is specially the suffix of judgement AKU filename.
PDA sends PDA program redaction solicited message to gateway, gateway returns to AKU version information on gateway by the gateway configuration Archive sit to PDA, after PDA receives the AKU version information, compare with current AKU version, if the AKU version on gateway is higher than the current version on PDA, PDA obtains the AKU of redaction from gateway, the redaction of preserving on gateway can be ZIP form and/or CAB form.
Step 104: after download was completed, PDA was restarted.
Please refer to Fig. 2, be the process flow diagram of PDA program upgrade of the present invention, can comprise the following steps:
After step 201:PDA is restarted, the operation ROMPaq;
Step 202: whether have ZIP bag or CAB bag under the AKU catalogue of detection PDA,, if exist, enter step 203, if, because failed download does not exist, enter step 206;
Step 203: detect and whether have the backup file folder,, if exist, empty the backup file folder,, if do not exist, create the backup file folder;
Step 204: after determining the existence of backup file folder and not comprising any file, PDA program All Files is copied to the backup file folder;
The backup file folder can comprise the AKU as the last revision of backup file, in step 204, needs to judge whether the backup file folder exists previous backup file,, if exist, deletes all backup files, then carries out this backup.
Step 205: after having copied, the ZIP bag or the CAB that install under the AKU catalogue wrap to carry out version updating;
Step 206: empty the AKU catalogue, and the PDA master routine under starting the operating system.
Reinstall AKU during for fear of PDA startup next time, preferably first empty the AKU catalogue in step 206, and then start the PDA master routine.
PDA of the present invention in the program upgrade process, backed up current version before version updating, thereby provided guarantee for version rollback.In the maintain pages of PDA of the present invention, newly-increased " version rollback " function,, as long as the user enters maintain pages, click " version rollback " and can use upgrading legacy version before.Below the present invention is realized that version rollback is elaborated.
Please refer to Fig. 3, the process flow diagram for PDA of the present invention carries out version rollback can comprise the following steps:
Step 301: when the failure of PDA program upgrade, PDA starts the version rollback function according to user's instruction;
Need to prove, in the present invention, upgrading unsuccessfully specifically refers to the PDA program and has been upgraded to redaction by step shown in Figure 2, but redaction is unstable, causes some functions to use.
Step 302: detect and whether have the backup file folder, if exist, execution step 303,, if do not exist, illustrate the not backup of previous legacy version of current version, the rollback failure, and flow process finishes;
The present invention creates the backup file folder when the PDA program upgrade, therefore, if the PDA program was carried out version rollback in the situation that never carry out upgrading, there do not is the backup file folder, rollback failure this moment, this time rollback of PDA prompting user failure, the user has to continue to use redaction.
Step 303: All Files in the backup file folder is compressed into ZIP wraps and be kept under the AKU catalogue;
Step 304:PDA is restarted, and the operation ROMPaq is installed the ZIP bag of the backup under the AKU catalogue, makes the previous legacy version of program rollback to current version.
In step 304, the process that the ZIP bag of backup is installed is specially step 201 to step 206, what difference was to install this moment is the ZIP bag after the All Files compression in the backup file folder, and step 201 is installed when the PDA program upgrade to step 206, is ZIP bag or CAB bag from gateway downloads.
After the user clicks " version rollback ", PDA has in fact only done the operation of compress backup file, after compressing successfully, PDA is restarted, auto-upgrade program moves automatically, detect whether AKU is arranged, the ZIP that the ZIP bag that at this moment backs up under the AKU catalogue can be taken as upgrading wraps and is installed in PDA, thereby has realized version rollback.
This shows, during the failure of PDA program upgrade, the user only need click " version rollback " just can use legacy version, need not to reinstall, thereby has saved the time, has improved user's experience.In addition, adopt the upgrading of ZIP bag,, because its committed memory space is less, can save space, can also avoid downloading and interrupting when unstable networks.
