The part or complete that the part or all of processing of some embodiments can be with other embodiments in above-mentioned various embodiments
Portion's processing is combined in any way, and the embodiment that combination is obtained still falls within embodiments of the present invention.For example,
The embodiment being respectively shown in for Fig. 1 and Fig. 2, can be combined in the following manner：First, it is frequent updating to determine that file updates
Still infrequently update；Then, used for infrequently more news at the various embodiments with reference to described in Fig. 1
Reason, is handled when frequent updating using the various embodiments with reference to described in Fig. 2.Updated by both files
Scheme can accomplish that read-write is kept completely separate, to solve the problem of prior art is present.
Various embodiments illustrate the file update scheme of the present invention, file by taking index file as an example, schematically below
Replication theme.
Search engine is the function of message area very core, and knowing required for user can be navigated to rapidly by search
Know.Below various embodiments by two kinds of search engine index Controlling models of design to solve the read and write abruption of index file
Problem.One kind is to update infrequently model, and one kind is to update frequent model, and different indexes is used according to different application scenarios
Controlling model.This model is specifically described respectively below.
【Update infrequently model】
This model is low mainly for index upgrade frequency, the larger situation of the amount of updating the data, because involving file copy
Operation, so being not suitable for index upgrade frequently scene, advantage is only to update to an index the inside, and index upgrade part is patrolled
Collect fairly simple.
The storage of index
As shown in figure 3, index file folder may include backup (Backup), prepare (Ready) and operation (Running) three
Sub-folder, wherein：
1) Running files are carrying out the file of write operation for index, are successfully tied when an index upgrade is operated
Shu Shi, under the index copy in Running files to Ready files；
2) Ready files preserve index file newest after last time renewal, and it act as reading for all searchers,
And in the index in indexing destruction Running, recover former index；
3) the index backup for specifying number, at the end of once-through operation is updated successfully, first are deposited under Backup files
Index in Ready files is backed up, if the number of backup exceedes the number specified, and deletes oldest a backup,
For example, backup when deleting 2016-01-25.
Under normal conditions, only one of which is in the state write in Running files and Ready files, therefore,
Have one in the error of arbitrary process, Ready files and Running files without destroyed, that is, this system be can
Self-recovery.
When occurring both in situation about writing (such as artificial outside modification), then this file system is unstable, is updated
Program is exited.
Under normal conditions, if being all substantial in Running and Ready files, and not in write-in
State, then they are the same, because Ready files are the last time backups of Running files.If between them
Uniformity destroyed, then can not judge that wherein which is correct, now more new procedures are exited.
Index upgrade
Need to do when needing index upgrade, check two file state in which, be described in detail below：
Running files do not have any reading and write operation.
Ready files may be read, but without write operation.
Judgment rule：
For Ready files：
1) there can only be one to write, be write from Running files, that is, from Running files copied index to Ready
Under catalogue；
2) it can be read with multiple, including：The reading of index upgrade module or the reading of Running Fault recoveries；
For Running files：
1) only one of which is read, from the reading of Ready files；
2) possible write for two kinds：One is writing of normally indexing, and another is writing for Fault recovery, from Ready files
What is pressed from both sides writes.
Hereafter the renewal to index is specifically described.Before this, first introduce in index upgrade flow and copy
Index the replicated folder flow used.
<Replicated folder flow>
Copied index uses all the elements in replicated folder flow, i.e. copy source (source) file to target
(target) file.
As shown in figure 4, replicated folder flow at least includes：
S401~S403. empties (clear) lock in the generation of target files, clears up target files, deletes clear
Lock；
S404, S405. read (read) lock in the generation of source files, and (write) lock is write in the generation of target files；
S406. the All Files in source files in addition to file is locked is replicated to target files；
S407, S408. delete the read lock in source files and the write locks in target.
<Index upgrade flow>
As shown in figure 5, index upgrade flow is as follows：
S501. check whether Ready files and Running files are normal, it is abnormal then to update failure, normally then turn
S502；
S502.Running files are for empty and Ready file non-NULLs, if it is not, then turning S505, if so, then turning
S503；
S503. Ready files are copied to and clip to Running files, that is, recover newest index；Wherein, flow is replicated
As described above, being not repeated herein.
S504. replicate and successfully then enter S505, otherwise update failure；
S505, S506. judge Ready and Running uniformity, unanimously then turn S507, otherwise update failure；
S507, S508. set up under Running files and write lock, are indexed renewal operation.
In the index upgrade flow, check whether Ready files are normal, that is, judge that Ready file rules are
File Ready may be read, but without write operation, flow is as shown in fig. 6, as follows：
S601. it is write-in or cleaning state to judge Ready files, if so, then clipping to index from Running files
Interrupted in the reproduction process of Ready files, turn S602, otherwise returned and check successfully；
S602. judging Running is write or for dummy status, is checked failure if so, then returning, is otherwise turned S603；
S603~S607. empties Ready files, by the copy content of Running files to Ready files, if
Whole process success, then return and check successfully, otherwise check failure.
In index upgrade flow, check whether Running files normally check rule：File Running does not have
There is any reading and write operation, flow is as shown in fig. 7, as follows：
S700. judge whether Running is currently written into or empties, if so, breaking during then indexing, turn S711,
Otherwise S721 is turned；
S711, S712. empty Running files, clear up successfully then return and check successfully, and failing then to return checks mistake
Lose；
S721. judge whether Running is reading, checked successfully if it is not, then returning, if so, then turning S722；
S722, S723. index are interrupted in the reproduction process for clipping to Ready files from Running files, are deleted and are read
Lock, deletes and successfully then checks successfully, otherwise returns and checks failure.
Index backup
Alternatively, embodiment also includes index backup procedure, i.e., index is backuped into Backup texts after index upgrade
Part is pressed from both sides.For example, as shown in figure 8, index backup procedure can include：
Whether S801.Ready files are currently written into, if so, can not then back up, otherwise turn S802；
S802. judge whether the number of backup file exceedes threshold value, more than S803 is then turned, otherwise turn S804；
S803. oldest backup is cleared up, then turns S804；
S804. Ready files are copied into Backup files；Wherein, the duplication flow of file is above in conjunction with Fig. 4
It is described, it is not repeated herein.
Searcher index upgrade
Searcher index upgrade flow refers to that the index that searcher is read in timing enters from the acquisition of Ready files is newest
The process of line replacement a, it is assumed that searcher has two index files of A and B to backup each other to use, its renewal process such as Fig. 9 institutes
Show, in general, judge whether the index currently run is newest, is not to copy the index under Ready to Backup
Archive index is simultaneously switched to searcher to index by file；Then two index files are all replaced into when being unused newest
.
【Update frequent model】
The model is mainly for index upgrade frequently scene, in the case of index upgrade is frequent, if using previous
Frequent copied index can be caused by planting model, influence efficiency.This model is by the way of two index lists can be read and write, simultaneously
Only one of which file writes the mode that a file is read.
Assuming that two index lists of A and B, when A is that current search device uses catalogue, then by last time and this renewal list
(List) catalogue B is written to, search catalogue then is switched into B goes to update write-in index A, such a process repeatedly, tool
Body flow such as Figure 10 institutes.Wherein, index list validity check flow is as shown in figure 11, as follows：
S1101. judge whether index list to be written damages, S1104 is turned if it is not, being then proved to be successful, if so, then turning
S1102；
S1102, S1103. empty index list to be written, while index to be updated will be copied to using index list
Catalogue；
S1104~S1106. updates index list, checks again for whether index is complete, completely then prompting is updated successfully, no
Then judge whether to exceed update times, update failure more than returning, otherwise turn S1102.
In summary, according to present embodiment, two kinds of search engine index control more new models of design solve different scenes
Under file update control problem, naturally it is also possible to expand to file renewal application scenarios.
File read-write can cause the generation of temporary file under file sharing scenario, and substantial amounts of disk can be taken by having accumulated long
Space, while can take substantial amounts of file handle can not discharge, thus, each embodiment of the invention is intended to the index by design
Update method can solve the problems, such as the read and write abruption of index, it is to avoid substantial amounts of .nfs temporary files occur, reduce accounting for for disk space
With, also, substantial amounts of file handle will not be taken in internal memory do not discharge, system is thus avoided because file handle is excessive and stops
File read-write is serviced.The scheme that the present invention is provided is not limited only to the control scene of search engine index file, may apply to and appoints
What file, which updates, needs the scene of read and write abruption.
Through the above description of the embodiments, those skilled in the art can be understood that the present invention can be by
The mode of software combination hardware platform is realized.Understood based on such, technical scheme makes tribute to background technology
That offers can be embodied in the form of software product in whole or in part, and the computer software product can be stored in storage and be situated between
In matter, such as ROM/RAM, magnetic disc, CD, including some instructions are to cause a computer equipment (can be individual calculus
Machine, server, or network equipment etc.) perform method described in some parts of each of the invention embodiment or embodiment.
Skilled person should be appreciated that disclosed above is only embodiments of the present invention, certainly can not be with
This limits the interest field of the present invention, and the equivalent variations made according to embodiment of the present invention still belong to the claims in the present invention institute
The scope covered.
