It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
Fig. 1 shows the flow diagram of the scan method of the data information of one embodiment of the invention.As shown in Figure 1,
This method includes：
Step S110：It is pre- to judge whether data information to be scanned meets according to the information capacity of data information to be scanned
If contractive condition.
Wherein, default contractive condition can be flexibly arranged, and the present invention does not limit specific set-up mode.For example, can be pre-
Capacity threshold is first arranged according to total amount of memory, information capacity is compared with capacity threshold, is waited for according to comparison result determination
Whether the data information of scanning meets default contractive condition for another example, can with dynamic access memory active volume, by information capacity with
Memory active volume is compared, and determines whether data information to be scanned meets default contractive condition according to comparison result.
Step S120：If so, being compressed to data information to be scanned, compressed data information is loaded into memory
In.
When determining that data information to be scanned meets default contractive condition, data information to be scanned is pressed
Contracting, and compressed data information is loaded into memory.Wherein, flexibly various compression algorithms can be used to realize when compression, only
It wants to achieve the purpose that reduce file size.In the present embodiment, both first file can be compressed in a hard disk and was finished
It is loading in memory, can also directly compressed while loading in memory afterwards.
Step S130：It is unziped it for the compressed data information loaded in memory.
This step can be both immediately performed after step S120 is finished, can also after step S120 is finished root
It is executed on demand according to needs.It is executed for example, it is also possible to just be directed to the same data message when needing using corresponding data information
Decompression.
Step S140：It is parsed for the data information after decompression, with the scanning of determination data information to be scanned
As a result.
By this step, analytic expression scanning can be carried out after decompression, to determine scanning result.Which passes through
Data information is compressed, only loads compressed data information in memory, so as to avoid due to data information is excessive
The problem of can not scanning, enables scan method suitable for all kinds of big files, has widened service application scene.
According to the scan method of data information provided in this embodiment, when the information capacity according to data information to be scanned
When judging that data information to be scanned meets default contractive condition, data information to be scanned is compressed, after compression
Data information be loaded into memory；It is parsed after being unziped it for the compressed data information loaded in memory,
With the scanning result of determination data information to be scanned.It can be seen which is by compressing data information, only including
Deposit the compressed data information of middle load, so as to avoid because data information is excessive can not scan the problem of, make scan method
Service application scene can have been widened suitable for all kinds of big files.
Fig. 2 shows the flow diagrams of the scan method of the data information of another embodiment of the present invention.In this implementation
In example, illustrated so that data information is to update the data information as an example.This updates the data the update packet that information can be to be downloaded
Etc. forms information, for realizing software or the more new function of system.Certainly, in other embodiments of the invention, data letter
Breath can also be loophole repair data information, for example, it may be the data information of the forms such as service packs, is repaired for realizing automatic
Function.As shown in Fig. 2, this method includes：
Step S210：It is pre- to judge whether data information to be scanned meets according to the information capacity of data information to be scanned
If contractive condition.
Due to the occupancy for being mainly used for reducing memory of the present embodiment, in favor of the scanning of big file, therefore, compression is preset
Condition can be arranged according to the information capacity and memory information of data information to be scanned.Default contractive condition is described below
Two kinds of possible realization methods：
In the first realization method, capacity threshold is set previously according to total amount of memory, by information capacity and capacity threshold
Value is compared, and determines whether data information to be scanned meets default contractive condition according to comparison result.Specifically, if memory
Total capacity is larger, then capacity threshold can be arranged larger；Conversely, then capacity threshold can be arranged smaller.Correspondingly,
When information capacity is more than capacity threshold, determine that data information to be scanned meets default contractive condition.Furthermore it is also possible in conjunction with
The external conditions such as scan frequency are arranged the capacity threshold.The realization method, which is equivalent to, pre-sets capacity threshold, every big
It is required to execute compression processing in the data information of the capacity threshold.
It, can be with dynamic access memory active volume, by information capacity and memory active volume in second of realization method
It is compared, determines whether data information to be scanned meets default contractive condition according to comparison result.Specifically, whenever acquisition
To after data information to be scanned, current memory active volume is obtained in real time, then according to the data information to be scanned
Comparison result between current memory active volume dynamically determines whether to meet default contractive condition.For example, if this waits sweeping
Ratio or difference between the data information retouched and current memory active volume meet certain condition be then determined for compliance with it is default
Contractive condition.Indeed, it is possible to according to ratio or difference between data information to be scanned and current memory active volume
One adjustable threshold value of dynamic is set, and is determined whether according to the threshold value to meet default contractive condition.Which can be adjusted dynamically
Whole contractive condition, so that current compression condition is more in line with current system mode.
In practical application, above-mentioned two kinds of realization methods both can be used alone, and can also be used in combination, the present invention is to this
It does not limit.
Step S220：If so, data information to be scanned is divided into multiple data blocks；Respectively be directed to each data block into
Row compression, obtains compressed data block, and data block index is established for the compressed data block；By the compressed data block
It is loaded into memory, and is indexed according to data block and generate index file.
When determining that data information to be scanned meets default contractive condition, data information to be scanned is pressed
Contracting, and compressed data information is loaded into memory.
Specifically, in the present embodiment, for the ease of being split processing to big file, memory headroom is saved to realize
Data information to be scanned is divided into multiple data blocks, and needle respectively by effect in advance before executing compression to data information
Each data block is compressed, obtains compressed each data block, and compressed each data block is loaded into memory
In.Wherein, when dividing data block, can according to the information sizes of the various pieces for including in data information, content type, make
It is divided with many factors such as frequencies.After division, it is directed to each data block respectively and executes compression processing, in order to follow-up mistake
Targetedly decompression operation is realized in journey.
In addition, for the ease of realizing targetedly decompression operation in the follow-up process, information inquiry efficiency is promoted,
In the present embodiment, data block index further is established for the compressed data block, and indexed according to data block and generate index text
Part.For example, when a data information is divided into five data blocks, it is directed to each compressed data block respectively and is arranged one
Data block indexes, and five data block indexes are stored in indexed file, in order to quickly position to corresponding data block.
Step S230：According to each data block index for including in index file, compressed each data are obtained respectively
Block, and be directed to each data block got respectively and unzip it.
This step can be both immediately performed after step S220 is finished, can also after step S220 is finished root
It is executed on demand according to needs.
For example, in a kind of specific business scenario, scanning engine can be handled as follows：
First, each data information to be scanned is all loaded onto in memory.This process correspond to step S210 and
Step S220.In the process, the essential attribute for needing to scan each data information, for example, file size, file type, text
Part renewal time etc.；Each data information is all loaded onto in memory according to essential attribute.For example, can sentence in the process
It is disconnected whether to need to execute compression processing to file, and preferentially load the file that need not be compressed；And/or it will need not compress
The file that file and needs compress is stored separately.In this step, if judging, a file meets default reduced rule, right
It is stored in memory after being compressed, to save memory headroom.
Then, the data information of the processing of needs is obtained from memory according to default processing sequence and executes scan process.
This process corresponds to step S230.Wherein, default processing sequence can be priority processing be not required to compression data, post-processing need
All kinds of Cahn-Ingold-Prelog sequence rules such as the data to be compressed.It can be seen that realized on demand on this process nature, according to current processing into
Degree obtains next data information to be scanned from memory.When specific acquisition, it is contemplated that if after some big files all decompress
Obtained file size is possible to be more than memory residue free space, even if being not more than memory residue free space, it is also possible to
Running efficiency of system is influenced because EMS memory occupation is excessive.In order to solve this problem, in the process, it is wrapped according in index file
The each data block index contained, obtains compressed each data block respectively, and be directed to respectively each data block for getting into
Row decompression.For example, it is assumed that a complete compressed data information includes altogether 10 data blocks, if simultaneously by 10 data
Block, which unzips to processing in memory, will cause memory consumption excessive, therefore, one only be decompressed every time according to the needs of actual treatment
Or two or three of data blocks can effectively prevent leading because data information is excessive to reduce the memory consumption in the same time
The phenomenon that causing scanning to fail.
Step S240：It is parsed for each data block after decompression, with sweeping for determination data information to be scanned
Retouch result.
Wherein, after step S230 is finished and gets a data block, then solution is extruded by this step
The data block come is parsed, and the analysis result of the data block is obtained.Finally, according to each number for including in a data information
Analysis result according to block is the entire scan result that can determine the data information to be scanned.
It can be seen that the present embodiment by executing compression processing in memory, (conventional compression processing is all in a hard disk
Realize) and directly store compressed file in memory, occupancy of the big file to memory can be effectively reduced, to carry
Rise running efficiency of system.Also, since compressed file can be decompressed according to data block, without primary for whole numbers
It is believed that breath is decompressed, therefore the amount of memory that big file occupies in scanning process is significantly reduced, even if file size is big
Scanning function can be also completed by this way in memory remaining space, to widen the application range of scanning function, made
Originally be limited to memory headroom and can not the application of application scanning function can also realize scanning function, to provide to the user more
Add comprehensive service.Which is particularly suitable in scanning more new scene, since update library is very huge, lead to tradition
Sweeping scheme can not apply update library scanning can effectively solve the problem that this problem after the scheme in the present invention.
In addition, those skilled in the art can also carry out various possible changes or extension to above-described embodiment.For example,
It executes and judges whether data information to be scanned meets default contractive condition according to the information capacity of data information to be scanned
Before step, following steps are can further include：
It monitors whether to receive shutdown command；Operation is intercepted if so, being executed for the shutdown command, and executes above-mentioned
Judge whether the data information to be scanned meets the step of default contractive condition according to the information capacity of data information to be scanned
Suddenly.
It can just be scanned since file to be scanned must be loaded in memory, can be occupied during scanning
Prodigious memory consumes many resources, and the use for influencing computer even results in it and can not use, to affect user just
It is often used computer, to solve the above-mentioned problems, can terminate to use computer in user, start to sweep after triggering shutdown command
Retouch process.It, can be by predefining the shutdown function for sending shutdown command, so when monitoring whether to receive shutdown command
Afterwards by hooking function or the other types of function of shutdown function can be associated with above-mentioned shutdown function is monitored, led to
Monitoring shutdown function is crossed so as to monitor whether to receive shutdown command in time.If so, can be by suspending shutdown command
Transmission mode come execute intercept operation.
Optionally, after executing the step of intercepting operation for shutdown command, in order to save resource, processing speed is promoted,
It is further target process, target end process by the Processes Tag unrelated with scan operation.For example open on computers
Such as document, the various loophole reparations such as browser operate unrelated process and can be marked as target process, and terminate above-mentioned
Target process.Unrelated process is operated with loophole reparation by turning off, the efficiency for executing loophole reparation operation can be improved, is reduced
Repair the occupied time.After target end process, executes the above-mentioned information capacity according to data information to be scanned and sentence
Break the data information to be scanned the step of whether meeting default contractive condition and subsequent step, finally when monitoring to wait sweeping
When the data information retouched is scanned, exit-entry operation is executed for above-mentioned shutdown command.Specifically, can be referred to by restoring shutdown
The mode of the transmission of order executes exit-entry operation.After system receives the shutdown command of transmission, shutdown behaviour can be executed at this time
It shuts down.
By above-mentioned execution step, computer can not be used in user, start data letter when triggering shutdown command
Scan procedure is ceased, is avoided when user uses computer, since scan data information occupies in a large amount of computer
The case where influencing user's normal use computer with resource is deposited, to greatly improve user experience.
