As preferably, data cached effective time is set, after exceeding effective time, then reads from server when application program visits again, and upgrade local cache and reset effective time.
As preferably, the concrete grammar of described data buffer storage is: adopt Key-value form to store in internal memory, and a corresponding priority memory access chain, when data cached be greater than designated recorder time by the tail record purge in preferential chain, most recently used relational links is formed together a priority memory access chain.
Compared with prior art, the invention has the beneficial effects as follows: by the file system of user-defined file system creation, local application program can be read and write cloud dish file easily, user just as to local file operation, achieves presenting and online editing network file to the operation of cloud dish file easily.
Accompanying drawing explanation
Fig. 1 is the data buffer storage block diagram of the present invention's wherein embodiment.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Arbitrary feature disclosed in this instructions (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
A kind of cloud dish file online editing method, concrete grammar is: the user-defined file system that establishment one is the same with generic file system on client operating system, namely under Windows, Android or linux system of client, user-defined file system is adopted to hang a virtual drive, by the user-defined file system of the File Mapping on cloud dish server to described client, all server is redirected to the file operation of virtual drive, by described user-defined file system, online editing is carried out to cloud dish file.By the file system of user-defined file system creation, local application program can be read and write cloud dish file easily, such user just as to local file operation, achieves presenting and online editing network file to the operation of cloud dish file easily.
No matter application program repeats how many times to same operation, described user-defined file system is by calling cloud dish file operation interface accessing cloud dish server, at this moment can by some data of Hash table cache current file, as file attribute, file have read block, file write-in block etc., the data of needs then can be obtained fast when application queries file attribute from local cache.
Hash(hash) be exactly that by hashing algorithm, be transformed into the output of regular length, this output is exactly hashed value the input of random length (crying preliminary mapping again, pre-image).This conversion is a kind of compressing mapping, and namely the space of hashed value is usually much smaller than the space of input, and different inputs may hash to identical output, so can not carry out unique determination input value from hashed value.
The present invention adopts open addressing to solve conflict: H=(H (key)+di) mod m, i=1,2 ..., k (k<=m-1), wherein H (key) is hash function, m is that hash table is long, di is increment sequence, and following three kinds may be had to follow the example of:
1) di=1,2 ..., m-1, be called linear hashing;
2) di=1^2, (-1) ^2 ..., ± (k) ^2 (k<m/2), is called quadratic probing hash again;
3) di=pseudo-random number sequence, is called that pseudo random number detects hash again.
Described user-defined file system is by the file operation interface of http protocol packaged cloud dish client-access server, comprise the establishment of file, delete, copy, read-write etc., and these file operation interfaces are registered the call back function of file system driver, the call back function routine that file system driver calls registration after receiving the request carrys out response request, and result is returned to user program by call back function routine.
Described method also comprises: carry out buffer memory to the current data of buffer memory that need of described user-defined file system, obtain when application queries file attribute to the data of this locality buffer memory from buffer memory.Use file operation optimization technology, multiple instruction folding is once performed instruction, and in conjunction with local cache function, making most instructions without the need to being performed to server by network delivery, reducing the mutual of client and server, improving the response efficiency of program.
Data cached effective time is set, as file attribute, file have read block, file write-in block etc., can fast return needs from buffer memory result during application program visit data next time.Data cached existence term of validity.After exceeding effective time, then read from server when application program visits again, and upgrade local cache and reset effective time, crossing after date needs synchronous with server data again.
Data cached have an effective time, after exceeding certain effective time, then needs to read from server when application program visits again, and upgrade local cache and reset effective time.After adding reading and writing data optimization module, the Internet Transmission of client and server can reduce by the access of about 30%.Such as, when the data that certain write instruction will write only have several byte-sized, buffer memory can be carried out within a certain period of time, wait for follow-up write instruction, if there is follow-up write instruction within this time period, front and back can be write instruction and perform in the lump; For another example, when the data that certain sense order will read only have several byte-sized, buffer memory can be carried out within a certain period of time, wait for follow-up sense order, if there is subsequent readout instruction within this time period, front and back sense order can be performed in the lump; If write or sense order do not have follow-up same alike result instruction within this time period, then perform this instruction after reaching this time; If the data length ratio writing or read is larger than setting amount, is then not suitable for buffer memory, directly performs.
The concrete grammar of described data buffer storage is: adopt Key-value form to store in internal memory, and a corresponding priority memory access chain, when data cached be greater than designated recorder time by the tail record purge in preferential chain, most recently used relational links is formed together a priority memory access chain.
As shown in Figure 1, when inserting new record, as handle quantity is less than limit value, then generate handle and be inserted into root node, handle quantity adds one; If handle quantity is greater than limit value, then delete last tail node, then generate handle and be inserted into root node, and often use a handle, by this node motion to beginning-of-chain.
