Brief description of the drawings
The attached drawing in the embodiment of the present invention is illustrated below, the attached drawing in embodiment be for the present invention into one
Step understands, is used to explain the present invention together with specification, does not form limiting the scope of the invention.
Fig. 1 is the document handling method flow chart of the present invention；
Fig. 2 is the document handling system composition frame chart of the present invention.
Embodiment
For the ease of the understanding of those skilled in the art, the invention will be further described below in conjunction with the accompanying drawings, not
It can be used for limiting the scope of the invention.
The present invention devises a kind of method that user class file system is established under windows operating systems.User hangs
The All Files operation carried out in load plate, such as create, read-write etc., the input of windows bottoms output I O managers can catch
And distribute, which reads client layer, then in User space by specific bottom document filtration drive by these events
Handle each file operation event under aspect, such as establishment, deletion and the read-write etc. of file, so as to fulfill user class file system
System.
Specifically, the present invention proposes a kind of document handling method, as shown in Figure 1, this method includes：
S101, the client layer hard disk for mapping out user class file system in windows systems in advance.
In embodiments of the present invention, existing catalogue in windows systems can be mapped as to new hard disk, simplified to text
The operation of part；The distributed file system of periphery can also be mapped under windows, realize the dilatation of file system.Need
Illustrate, above-mentioned interior with being only one embodiment of the present of invention, the scheme that can also take any other can implement is realized
The solution of the present invention.
S102, windows system catch windows systems in carry all I O operation request.
In embodiments of the present invention, windows bottoms I O managers can catch all I that user carries out in carry disk
O operation, such as create, read and write, deleting etc..
S103, when windows systems judge captured I O operation request be for client layer hard disk I O operation
During request, by distribute queue by I O operation request be distributed to user class file system.
In embodiments of the present invention, windows systems catch all I for being carried out in carry hard disk of user after O operation,
Can to each I O operation judge, if it is judged that the I O operation be windows systems local hard drive implement operation,
Then directly in windows systems to the I O operation carry out processing locality, if it is judged that the I O operation to be mapped in
The operation that the client layer hard disk of user class file system under windows systems is implemented, windows systems pass through specific bottom
Filter Driver on FSD, by these I O operation read in the form of distributing queue in user class file system.
S104, user class file system to the I O operation request handle.
Preferably, user class file system to I O operation request carry out processing and include：
The distribution queue of S1041, user class file system real time polling windows systems, obtain client layer hard disk I O
Operation requests.
In embodiments of the present invention, the poll thread in user class file system can always poll windows systems point
Send out queue, find distribution queue in pending I O operation request then read in user class file system.
S1042, user class file system according to the I of acquisition O operation ask corresponding action type readjustment and the operation class
The corresponding call back function of type.
Wherein, call back function is pre-created, and is registered in user class file system.
In embodiments of the present invention, understand in advance in user class file system to various I O operations to be processed are asked,
Such as, establishment, read-write, delete operation etc., are respectively created corresponding call back function, and each call back function of establishment is existed in advance
Registered in user class file system.When poll thread find pending I in distribution queue O operation ask and read
After into user class file system, readjustment thread can be directed to the I O operation request action type, e.g., create, read and write, delete
Division operation etc., readjustment and the corresponding call back function of the action type.
S1043, according to the call back function to the I of client layer hard disk O operation request handle.
In embodiments of the present invention, due to call back function and client layer hard disk I O operation request action type it is opposite
Should, therefore, processing thread can directly according to the call back function to the I of client layer hard disk O operation request handle.
Preferably, according to call back function to the I of client layer hard disk O operation request carry out processing and include：
By the I of multiple client layer hard disks of no dependence O operation ask corresponding multiple call back functions, be distributed to
Multiple threads are handled at the same time, and/or by the I of multiple client layer hard disks with dependence O operation request it is corresponding multiple times
Letter of transfer number, is distributed to a thread and is handled.
Preferably, this method further includes：
S201, user class file system from windows systems in advance obtain user class file system various I O operation
Required data and metadata.
The data and metadata, be stored in advance in the data buffer area of user class file system by S202.
S203, in user class file system carry out I O operation when, user class file system is directly from data buffer area
Obtain the data and metadata.
With this solution, it is not necessary to every time into windows systems obtain user class file system each I O operation institute
The data and metadata needed, it is possible to increase the access speed of user.
Wherein, when I O operation include with modification property I O operation operation when, for example, write operation, set file category
Property, renaming etc., when user class file system carry out the I with modification property O operation after, user class file system cancels number
According to stored in buffer area with the I with modification property the corresponding data of O operation and metadata.Caller can also be from remote
Interim pressure in windows systems is held to obtain new data.It can so ensure the uniformity of data.
Preferably, this method further includes：
User class file system to I O operation request handle when, user class file system record user class file
The operation information of system simultaneously generates operation log, by operation log be saved in I O operation ask in corresponding log object,
And log object is saved in file by the way that daily record thread is asynchronous.With this solution, user class file system can also be positioned
Bug, it is convenient to be provided for system maintenance.
