For solving the problems of the technologies described above, the embodiment of the present invention provides a kind of commingled system file data processing method and system, by increasing file directory corresponding to insensitive agreement, and to there being the file of conflict to carry out rename processing, and preserved the corresponding relation of conflict filename, with less system overhead, solve file access conflict, improved operating efficiency.

In order to make those skilled in the art person understand better the technical scheme in the present invention, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, should belong to the scope of protection of the invention.

Embodiment mono-

Referring to Fig. 1, commingled system file data processing method the first embodiment schematic diagram providing for the embodiment of the present invention.Embodiment shown in Fig. 1 is applied in commingled system, and described commingled system is at least supported the first file protocol and the second file protocol, and wherein, described the first file protocol is to filename case sensitive, and described the second file protocol is insensitive to filename capital and small letter.Wherein, the first file protocol includes but not limited to the agreement to filename case sensitive such as NFS, and the second file protocol includes but not limited to that CIFS etc. is to the insensitive agreement of filename capital and small letter.Described commingled system can also be supported various protocols, for example, support three kinds or three kinds of above different agreements.Described commingled system can be mixed file system, can be also the system of other types, for example, can comprise that needs externally provide the network system of case sensitive and the insensitive operation of capital and small letter simultaneously, and the present invention does not limit this.Commingled system take below as mixed file system, support the agreement of case sensitive simultaneously and be that example describes to the insensitive agreement of capital and small letter.As shown in Figure 2, be embodiment of the present invention application scenarios schematic diagram, NFS client and CIFS client can be accessed commingled system simultaneously, and commingled system is supported two kinds of different file protocols simultaneously.

S101, when receiving file interpolation request, adds according to described file the protocol-identifier comprising in request and determines file processing pattern; Described file processing pattern at least comprises the first file processing pattern corresponding with described the first file protocol and the second file processing pattern corresponding with described the second file protocol.

S102, when definite file processing pattern is the first file processing pattern, judgement needs the first filename corresponding to file adding whether to have conflict filename in the first file directory and the second file directory; Wherein, described the first file directory is corresponding with described the first file protocol, and described the second file directory is corresponding with described the second file protocol.

S103, when judgement needs first filename corresponding to file of interpolation not have the filename of conflict in described the first file directory and have the filename of conflict in described the second file directory, in described the first file directory, preserve described the first filename, in described the second file directory, preserve described the first filename is carried out to the second filename that conversion process obtains, and preserve the mapping relations of described the first filename and described the second filename; Wherein, described the first filename and described the second filename are different filenames in the second file protocol.

It should be noted that, commingled system can receive file and add request, and described file adds request can, from data access end, include but not limited to NFS client, CIFS client etc.At file, add in request, carry protocol-identifier, for showing supported different agreement.For example, at file, add in request and carry the first protocol-identifier, for showing to support the first file protocol, the first file protocol is to filename case sensitive.And for example, at file, add in request and carry second protocol sign, for showing to support the second file protocol, second agreement is insensitive to filename capital and small letter.Correspondingly, commingled system can comprise multiple file processing pattern, and described file processing pattern at least comprises the first file processing pattern corresponding with described the first file protocol and the second file processing pattern corresponding with described the second file protocol.Wherein, the first file processing pattern is the tupe to filename case sensitive, and the second file processing pattern is to the insensitive tupe of filename capital and small letter.When commingled system is supported various protocols, it can also comprise the alternative document tupe corresponding with each agreement.

It should be noted that, in a kind of implementation of the present invention, in creating file process, according to definite file processing pattern, preserve the corresponding relation of file and file processing pattern, when needs, file is carried out search, deletion etc. is when operate, can in file operation requests, not carry protocol-identifier, but according to the file of preserving and the corresponding relation of file processing pattern, determine the file processing pattern corresponding with described file, to carry out corresponding operation.

It should be noted that, when specific implementation of the present invention, created the first file directory and the second file directory, wherein, corresponding the first file protocol of the first file directory, for the first file protocol provides directory index; Corresponding the second file protocol of the second file directory, for the second file protocol provides directory index.Particularly, the first file directory can be referred to as again CSDIR(case sensitive directory, responsive catalogue).Meanwhile, another file directory of introducing in the attribute of parent directory (the second file directory) can be referred to as again CIDIR(case insensitive directory, insensitive catalogue), both provide different directory index for different agreements.For duplication of name file, after filename is revised, (as: AA～1) is stored in CIDIR.As shown in table 2 and table 3, it is the example of responsive catalogue and insensitive catalogue.

The responsive catalogue CSDIR of table 2

When determining that file processing pattern be the first file processing pattern to filename case sensitive, judgement needs first filename corresponding to file of interpolation whether to have conflict filename in the first file directory and the second file directory.When judgement needs first filename corresponding to file of interpolation not have the filename of conflict in described the first file directory and have the filename of conflict in described the second file directory, in described the first file directory, preserve described the first filename, in described the second file directory, preserve described the first filename is carried out to the second filename that conversion process obtains, and preserve the mapping relations of described the first filename and described the second filename.The filename of conflict generally refers to the filename that occurs duplication of name.

Further, described method also comprises: when definite file processing pattern is the first file processing pattern, and when judgement needs first filename corresponding to file of interpolation all not have the filename of conflict in described the first file directory and described the second file directory, in described the first file directory and described the second file directory, preserve described the first filename respectively.

During specific implementation, when determining that file processing pattern is the first file processing pattern to filename case sensitive, first will be in the first file directory locating file whether there is the filename of conflict, if there is no, create file, and add file in the first file directory.Particularly, during file first filename by name of the file adding when needs, when judgement does not exist the filename of conflict in the first file directory, in the first file directory, preserve described the first filename.Then, in the second file directory, search the filename that whether has conflict, if there is no, directly in the second file directory, add described the first filename; If there is the filename of conflict, need that the first filename is carried out to conversion process and obtain the second filename.The mode of conversion process can be very flexibly, includes but not limited to unified be converted to capitalization and add suffix, be unifiedly converted to small letter and add suffix, or the unified feature title that is revised as agreement etc., at this, do not limit.For example, suppose in the first file directory and the second file directory, only to preserve aa file in commingled system, when need to add the file of file Aa by name under the first tupe, in first file directory corresponding with the first file processing pattern, search and do not have Aa file, directly in the first file directory, preserving Aa file.Then, in the second file directory, search the filename that judgement has conflict, Aa file is carried out to rename conversion process, be converted into AA-1, and preserve filename and relevant information after conversion in the second file directory.

Meanwhile, need to preserve raw filename is the mapping relations between the second filename after the first filename and conversion.The mapping relations of preserving can have multiple implementation.In a kind of possible implementation, the mapping relations of described the first filename of described preservation and described the second filename comprise: in the first mapping table, create with the first file key by name, with the key-value pair of the second file value by name; In the second mapping table, create with the second file key by name, with the first file key-value pair being worth by name; Wherein, described the first mapping table and described the first file protocol, described the first file directory are corresponding; Described the second mapping table and described the second file protocol, described the second file directory are corresponding.Describe for example corresponding the first file protocol of the first mapping table (CSTable, case sensitive table), the first file directory and the first tupe below; Corresponding the second file protocol of the second mapping table (CITable, case insensitive table), the second file directory and the second tupe.As table 4 and table 5 are depicted as the example of the first mapping table and the second mapping table.

Table 4CSTable

Key (sensitive document name)	Value (insensitive filename)
		Aa	AA-1
AA	AA-2
		…	…

Table 5CITable

Key (insensitive filename)	Value (sensitive document name)
		AA-1	Aa
AA-2	AA
		…	…

It should be noted that, the first filename of preserving and the mapping relations of the second filename can also adopt other forms to carry out index, if for example mapping table can be by key (key) value of finding (value), also can find key (key) by value (value), the second mapping table CITable and the first mapping table CSTable can be reduced to a mapping table, reduce to a certain extent the existence of redundant data.In addition, the file directory in the present embodiment (entry table), mapping table all can have many forms, as B tree, B+ tree and Hash table etc., at this, do not limit.

Thus, in the embodiment of the present invention, support at the same time to the first file protocol of case sensitive and in the commingled system of insensitive the second file protocol of capital and small letter, first file directory corresponding with the first file protocol and second file directory corresponding with the second file protocol have been created, when needs add file, in the first file directory and the second file directory, search the filename that whether has conflict respectively, while there is the filename of conflict if there is not the filename of conflict in to the first file directory of case sensitive in insensitive the second file directory to capital and small letter, by filename is carried out to conversion process, and the corresponding relation of the filename before preservation conversion and the filename after conversion, thereby solved the problem that file data that the filename conflict that exists in multi-protocols file system causes can not normally be accessed, and to filename, conflict is processed in file system inside, complexity and the expense of system have been reduced, and effectively promoted operating efficiency.

Embodiment bis-

Referring to Fig. 3, commingled system file data processing method the second embodiment schematic diagram providing for the embodiment of the present invention.

On the basis of first embodiment of the invention, method provided by the invention also further comprises the processing procedure of file data being added under the second tupe.

S301, when definite file processing pattern is the second file processing pattern, when judgement needs first filename corresponding to file of interpolation all not have the filename of conflict in described the first file directory and described the second file directory, in described the first file directory and described the second file directory, preserve described the first filename respectively.

S302, the first filename corresponding to the file that need to add when judgement when there is the filename of conflict or have the filename of conflict in described the second file directory in described the first file directory, backspace file name duplication of name error messages.

During specific implementation, when add protocol-identifier in request according to file, determine that file processing pattern is when to insensitive the second file processing pattern of filename capital and small letter, first will be in second file directory corresponding with second protocol locating file whether there is the filename of conflict, if there is no, create file, and add file in the second file directory.Particularly, during file first filename by name of the file adding when needs, when judgement does not exist the filename of conflict in the second file directory, in the second file directory, preserve described the first filename.Then, in the first file directory, search the filename that whether has conflict, if there is no, directly in the first file directory, add described the first filename.

If there is the filename conflicting with the first filename, backspace file name duplication of name error messages in judgement in the second file directory.

If there is not the filename conflicting with the first filename and have the filename conflicting with the first filename in the first file directory in judgement, can backspace file name duplication of name error messages in the second file directory yet.

Thus, through above-mentioned processing, avoided supporting the file access incorrect problem that the commingled system of multi-protocols is born the same name and caused due to file, and because bearing the same name in file system inside to conflict, the present invention processes, with less system overhead, efficiently solve the problem that file data that the filename conflict that exists in multi-protocols file system causes can not normally be accessed, and to filename, conflict is processed in file system inside, reduce complexity and the expense of system, and effectively promoted operating efficiency.

Referring to Fig. 5, commingled system file data processing method the 4th embodiment schematic diagram providing for the embodiment of the present invention.

In fourth embodiment of the invention, on the basis of front several embodiment, also further comprise the treatment step that file object is carried out to deletion action.

S501, when receiving file deletion requests, determines the file processing pattern corresponding with described file deletion requests.

During specific implementation, can determine the file processing pattern corresponding with described file deletion requests according to the protocol-identifier containing in file deletion requests.For example, carry the first protocol-identifier in file deletion requests, for showing to support the first file protocol, the first file protocol, to filename case sensitive, determines that file processing pattern is the first file processing pattern to filename case sensitive.And for example, at file, add in request and carry second protocol sign, for showing to support the second file protocol, second agreement is insensitive to filename capital and small letter, determines that file processing pattern is to insensitive the second file processing pattern of filename capital and small letter.

In the implementation of another possibility, in creating file process, according to definite file processing pattern, preserved in advance the corresponding relation of file and file processing pattern.Therefore, when needs, file is carried out and searched, during the operation such as deletion, can in file operation requests, not carry protocol-identifier, but according to the file of preserving and the corresponding relation of file processing pattern, determine the file processing pattern corresponding with described file, to carry out corresponding operation.

S502 according to definite file processing pattern, searches the filename that whether exists file to be deleted corresponding in the file directory corresponding with described file processing pattern.

When definite file processing pattern is the first file processing pattern, in the first file directory, search the filename that whether exists file to be deleted corresponding.When definite file processing pattern is the second file processing pattern, in the second file directory, search the filename that whether exists file to be deleted corresponding.If there is no, return to error message.

S503 when determining while there is filename corresponding to file to be deleted, deletes respectively described file to be deleted in the first file directory and the second file directory.

During specific implementation, after determining and having the filename that file to be deleted is corresponding, before deleting described file to be deleted respectively in the first file directory and the second file directory, described method also comprises: judge whether to exist the mapping relations corresponding with the filename of file to be deleted.When judgement exists mapping relations corresponding to filename with file to be deleted, according to the mapping relations corresponding with described filename, in the first file directory and the second file directory, delete respectively described file to be deleted, and delete described mapping relations; When judgement does not exist mapping relations corresponding to filename with file to be deleted, directly in the first file directory and the second file directory, delete described file to be deleted.

Particularly, when judgement exists mapping relations corresponding to filename with file to be deleted, need to find the first file directory and/or the second file directory filename corresponding with the filename of the file that will delete according to the mapping relations of preservation.For example, when the lower deletion of the first tupe (sensitive mode) Aa file, there is the mapping item corresponding with Aa file in judgement, at the first mapping table and the second mapping table, search respectively, judge that its file of preserving is Aa in the first file directory, according to mapping relations, obtain its file of preserving AA-1 by name in the second file directory, when carrying out deletion action, the file of deleted file Aa by name in the first file directory, the file of deleted file AA-1 by name in the second file directory.And, delete the mapping relations that find, for example in the first mapping table and the second mapping table, remove the mapping item corresponding with Aa file simultaneously.If there is not the mapping item corresponding with Aa file in judgement, in the first mapping table and the second mapping table, all there is not the object Aa that will delete, illustrate that Aa file is identical with the filename in the second file directory in the first file directory, there is not the filename of conflict, directly in the first file directory and the second file directory, delete described file to be deleted.

Embodiment five

S601, while receiving file deletion requests, determines whether sensitive mode deleted file object.If so, enter step S602; If not, enter step S603.

S602 searches the file object that needs deletion in the first file directory CSDIR, obtains lookup result, enters step S604.

S603 searches the file object that needs deletion in the second file directory CIDIR, obtains lookup result, enters step S604.

S604, when lookup result shows to have file object to be deleted, enters step S605; Otherwise, return to error message, termination routine.

S605, determines whether sensitive mode deleted file object, if so, enters step S606; If not, enter step S607.

S606, searches object at the first mapping table, obtains lookup result, enters step S608.

S607, searches object at the second mapping table and obtains lookup result, enters step S608.

S608, if existed, enters step S609.If there is no, enter step S610.

S609, removes object to be deleted in the first file directory CSDIR, removes object to be deleted in the second file directory CIDIR, removes object to be deleted in CITDIR, removes object to be deleted in CSTable, process ends.

S610, removes object to be deleted in the first file directory CSDIR, removes object to be deleted in the second file directory CIDIR, process ends.
