Embodiment
Core of the present invention is a system in the personal settings that caused by upgrading after the system configuration information generation in the CONFIG.SYS is applicable to system reset after the back that resets is according to personal settings information in the personal settings file before resetting and system reset; The personal settings that system will form after resetting are saved in the personal settings file, so that system reuses in follow-up resetting.
Say more specifically whether the present invention at first exists the personal settings file in the check system when the device systems initial start, if there is no, then create only the personal settings file of include file head control information, a start-up system then; If exist, then direct start-up system.
After system reset, generate the personal settings that are applicable to after the system reset according to the system configuration information in the CONFIG.SYS after personal settings information in the personal settings file before resetting and the system reset, promptly, effective information in the personal settings file is updated in the configuration file that matches, keeps the configuration information that configuration file is not complementary with personal settings information.
After the back personal settings information that obtains resetting, system is saved to this personal settings information in the personal settings file, and new personal settings are continued to generate according to these personal settings in the back so that system resets once more.
In the renewal and storing process of personal settings, system carries out invalid record inspection according to weights to the personal settings file in the back that resets at every turn, by flag parameters invalid record is carried out mark, regularly clears up invalid record according to the number of resets that sets.Described invalid record is the record of storage invalid information in the personal settings file.
Below in conjunction with the specific embodiment of the invention accompanying drawing the present invention is elaborated.
The present invention increases a file that is used to store personal settings information in system, in the present embodiment this document is called the personal settings file.
Described personalized configuration file is not upgraded with the upgrading of device systems, resides in forever in the device systems, and the data structure of this document is described as shown in table 1:
Table 1: the data structure of personal settings file
As shown in table 1, shown in mainly comprise file header control information and file logging information in the personal settings file, wherein the file header control information comprises bNBResetTimes, bNeedTrimTimes, four parameters of bCurrBytes, bLastBytes; Comprise bValidFlg, bWeights, three parameters of content in the file logging information.
Each parameter in file header control information and the file logging information all is introduced with field, type, implication and feature and functional description four parts.In the last table implication of each parameter representative and the effect in system will be in the work of the embodiment of the invention imbody.
The method that the embodiment of the invention is carried out the smooth upgrade configuration information is as follows:
Step 1, when the device systems initial start, if there is not the personal settings file in the system, then system needs to create earlier an only personal settings file of include file head control information, system start-up after creating this document; If there has been the personal settings file in system, then system directly starts.
Step 2, the effective information in the personal settings file is updated in the configuration file that matches, keeps the configuration information in the unmatched configuration file, generate the new personal settings information that is applicable to the current back system that resets.
After each device systems resets, according to the snapshot of configuration file in the internal memory, every in the personal settings file effective record is updated in the configuration file, for every effective information of personal settings file weights are set simultaneously.
Described configuration file snapshot has been preserved the key message in the configuration file, and system can directly obtain this information by reading internal memory, need not repeatedly to visit peripheral hardware; System by check in the personal settings file information whether with snapshot in the keyword of configuration file be complementary and judge one by one whether the information in every record in the personal settings file effective.
For the effective record that has matching relationship, the most significant digit of the weights bWeights that then should write down is set to 1, that is: bWeights |=2^7, and simultaneously, system is updated to the effective information in the personal settings file in the record that configuration file matches;
For the information that does not have matching relationship, then do not carry out information updating, the scale-of-two weights that will store this recording of information simultaneously move to right one, make these weights be reduced to half original bWeights=bWeights/2.
Like this after the system reset, promptly increase the part of the back system that is fit in the information of the personal settings that the user carried out to reset in the configuration file before system reset, kept some information of this system itself again, formed to succession the personal settings of this system.
Step 3, obtain in configuration file in the personal settings information of current system, the personal settings information that obtains in the configuration file need be saved in the personal settings file, its concrete preservation divides three kinds of situations to carry out.
First kind of situation be, in the personal settings file, can find with configuration file in the information entry that is complementary of the new personal settings information that forms, its method for subsequent processing is as follows:
The entry that the personal settings information updating is complementary with it to the personal settings file, and weights high position 1 that will this item, promptly bWeights|=2^7 if former bValidFlg is invalid simultaneously, then is changed to it effectively;
Second kind of situation be, can not find the information entry that is complementary with this personal settings information in the personal settings file, but can find (first) invalid record item, and its method for subsequent processing is as follows:
In first invalid information entry that the personal settings information updating is found to the personal settings file, weights extreme higher position 1 that simultaneously will this item, i.e. bWeights|=2^7, and original invalid bValidFlg was changed to effectively;
The third situation is, can not find the information entry that is consistent with this personal settings information in the personal settings file, also can not find the invalid information entry simultaneously, and its disposal route is as follows:
Increase an information record in the personal settings file newly, the content of this entry is set to the content of the personal settings information in the configuration file, weights high position 1 that simultaneously will this item, i.e. and bWeights|=2^7, and bValidFlg is changed to effectively.
When system resets,, can judge whether each information record is the invalid information record in the personal settings file according to flag parameters bValidFlg and weights because the personal settings file all may produce the invalid information record after resetting at every turn.
At first need to preestablish the weights decision threshold standard that a judgement information is recorded as the invalid information record.Standard among the present invention is: when the parameter b ValidFlg of certain bar information record in the personal settings file is shown as when invalid, show that then this is recorded as invalid record, promptly show weights＜predefined standard of this moment, then temporarily skip and do not do other processing; When the parameter b ValidFlg of certain bar record in the personal settings file is shown as when effective, and when its bWeights＜predefined standard (for example 2^4), then the bValidFlg that will write down be changed to invalid.
After system start-up, when system upgrades or system is in operation when some fault occurring, then system all needs to reset.
When system resets,, therefore after resetting, need to determine and remove invalid record through several times because the personal settings file all may produce invalid record after resetting at every turn.
The method that determines when the cleaning invalid record is:
After each system resetted, the numerical value that is used for the parameter b NBResetTimes of register system number of resets added 1;
If the numerical value after the system reset among the parameter b NBResetTimes does not then carry out the invalid record cleaning less than the numerical value of the invalid record cleaning trigger parameter bNeedTrimTimes that pre-sets;
If the numerical value after the system reset among the parameter b NBResetTimes is more than or equal to the numerical value of the invalid record cleaning trigger parameter bNeedTrimTimes that pre-sets, then invalid record is cleared up, and after invalid record cleaning is finished with the numerical value zero clearing among the bNBResetTimes.
In addition,,, often need in this document record, preserve more information afterwards, therefore just need the file logging size of dynamic expansion this document along with the operation and the actual needs of system because the present invention resides in this personal settings file in the system forever.
Need to use two parameters in the control information of personal settings file header in the process of dynamic expansion file logging size:
BCurrBytes, given structure is obtained the byte number of current file logging when being used for from design;
BLastBytes, the byte number of every file record before being used for register system and resetting.
The dynamic adjusting method that the present invention proposes is described below:
Finish the expandability of record by both cooperations of bCurrBytes, bLastBytes in the control information of personal settings file header, allow from the end of record increase, deletion information;
When device systems starts, when both are worth inconsistently, then will write down and change to the bCurrBytes byte number by the bLastBytes byte number:
As bLastBytes＞bCurrBytes, the byte that every end of record of amputation has more, by the quantity of amputation byte is the poor of bLastBytes and bCurrBytes, the situation of bLastBytes＞bCurrBytes seldom occurs in practice, and the overwhelming majority all is the situation of bLastBytes＜bCurrBytes;
As bLastBytes＜bCurrBytes, add the byte that lacks at every end of record, so just realized expansion to file logging;
Add byte quantity be the poor of bCurrBytes and bLastBytes, the byte content of interpolation is changed to the initial value of acquiescence, for example can be set to 0xff;
The record length expansion finishes, and the bLastBytes value is changed to the numerical value of bCurrBytes.
