Embodiment one
Fig. 1 is a kind of flow chart of method for releasing resource provided in an embodiment of the present invention.Referring to FIG. 1, resource release sideThe specific steps of method include:
Step S10: when the main thread of business process, which receives resource, to release order, started by main thread independently of masterThe worker thread of thread.
It should be noted that the business process in this step characterized is the business for being in working condition, business can be withIt is interpreted as providing a user the computer program of related service.Business constantly responds direct or indirect by user during the work timeThe operational order of initiation is substantially business process after receiving operational order, by the operational order be transmitted to business intoThe main thread run in journey, and corresponding business operation is carried out according to the intention that operational order is characterized by main thread.This stepIt is to pass through main line when the main thread of business process receives the resource that characterization removes the data in memory and releases orderCheng Qidong in subsequent steps with this replaces main thread pair by worker thread independently of the worker thread of main thread itselfResource, which releases order, to be handled.In addition, the worker thread of this step and main thread are concepts in contrast, that is to say, that mainThread and worker thread are substantially the thread for being able to carry out task processing, and distinctive points functionally are only that, main threadFor handling the task in new arrival business other than removing internal storage data, and worker thread is newly arrived for individually handling main threadCarry out the task of the removal internal storage data in business.
Step S11: it is released order by worker thread according to resource and removes corresponding data in memory.
It is understood that this step releases order progress to resource in a manner of being asynchronous to main thread worker threadCorresponding operation, is realized to be released order according to resource with this and removes the final purpose of corresponding data in memory, due to memoryMiddle institute's storing data, which remove, is well known to those skilled in the art technology contents, therefore does not do specifically repeat herein.
Method for releasing resource provided by the present invention is released when the host process of business process receives characterization internal storage data needsWhen the resource put releases order, host process starting and itself mutually independent worker thread, and then by worker thread according to moneySource, which is released order, removes corresponding data in memory.This method receives after resource releases order in the main thread of business process,The relevant operation that releasing memory resource is individually performed in independent worker thread is opened, therefore middle main thread needs compared with the prior artFor first responding subsequent work order again after memory source discharges, the main thread in this method is internal without carrying outThe removal operation of corresponding data in depositing, can respond the follow-up work instruction of business process, therefore being capable of relative reduction businessThe whole time delay of main thread responsive operation instruction, and then can ensure the whole work efficiency of business.
Embodiment two
On the basis of the above embodiments, the present invention also provides a series of preferred embodiments.
As a preferred embodiment, it is characterized in that, data include Inode data and content-data；
Correspondingly, specifically being wrapped by worker thread according to resource the step of removing corresponding data in memory of releasing orderIt includes:
By Inode data retrieval to memory in corresponding content-data remove；
Remove Inode data.
It should be noted that Inode data, that is, index node data are wrapped for storing the essential information of archives and catalogueContaining time, shelves name, user and group etc., Inode data can be understood as it is interior there are in actual hardware equipment access content numberBe the data of description content data according to required metadata, mainly describe data attribute information, thus with content numberThere are corresponding relationships between.Under actual scene, when needing to read data during vocational work, the number is usually first obtainedIt stores according to corresponding Inode data, and then by Inode data to memory, it is further more efficiently quasi- according to Inode data with thisTrue gets required content-data, therefore under current scene, after business is completed to the use of content-data, leads in memoryOften it has been stored with Inode data and corresponding content-data.In order to more agree under currently used scene to content-dataAcquisition modes, further ensure in memory resource discharge overall effect, present embodiment remove memory inWhen corresponding data, first according to Inode data retrieval to and remove corresponding content-data in memory, and then will be used for againThe Inode data that content-data is retrieved in memory are deleted, and opposite can ensure that total data relevant to content-data is equal with thisMemory is removed out, it is opposite to improve the comprehensive of resource release, the generation of dirty data is avoided, memory headroom is further improvedAvailability.

On the basis of the above embodiment, as a preferred embodiment, obtaining other Inode data and singleSolely after write-in to memory, this method further comprises:
According to the corresponding object content data of other Inode data acquisitions, and object content data are written to memory.
Due to consideration that content-data corresponding to other Inode data in memory can Inode data in memoryBefore being removed, it is removed as the corresponding content-data of Inode data, therefore even if by it after removing Inode dataNested other Inode data be separately written to memory, business is needing content-data corresponding to other Inode dataWhen, it is still necessary to first corresponding content-data is read in External memory equipment according to Inode data and is stored to memory, but thisOne operation can undoubtedly generate certain delay, cause business that can not efficiently get required content-data in memory.ThisEmbodiment is obtaining other Inode data and is being separately written to memory, according to other corresponding targets of Inode data acquisitionContent-data, and object content data are written to memory, and then when business is needed using the corresponding content of other Inode dataIt when data, can directly be obtained in memory according to Inode data, without consuming biggish time overhead in External memory equipmentMiddle reading further ensures the whole efficiency of vocational work.
In addition, as a preferred embodiment, being removed in memory being released order by worker thread according to resourceAfter corresponding data, this method further comprises:
Worker thread is hung up, and when main thread receives new resources and releases order, auxiliary line is waken up by main threadJourney is released order corresponding new data with removing in memory with new resources.
It should be noted that being to control worker thread in a dormant state by the essence that worker thread is hung up, due to consideringStarting to thread needs to occupy certain system resource, and in the case where system resource is relatively in short supply, the starting of thread is oftenIt needs that available system resource is waited to reach load quantity, therefore is difficult to ensure that worker thread can be in resource under actual sceneIt releases order and completes to start at once when arriving, present embodiment is released order by worker thread completion to resourceAfter processing, worker thread is hung up, i.e., does not discharge the system resource that worker thread has occupied, and then when main thread receives newlyWhen resource releases order, can immediately pass through main thread wake up worker thread so that worker thread processing new resources release order,The whole efficiency of resource release is further ensured that with this.
On the basis of a series of above-mentioned embodiments, as a preferred embodiment, passing through worker thread rootIt releases order and is removed in memory before corresponding data according to resource, this method further comprises:
Resource lock is arranged to data.
It should be noted that due to consideration that, it is removed in memory accordingly being released order by worker thread according to resourceData during, business process may receive the operational order for the data, in order to ensure business normally holdRow, should be avoided business process and gets the data removed in memory, due to the sheet removed for the data in memoryMatter is the formatting modification to data, therefore present embodiment removes in memory being released order by worker thread according to resourceBefore corresponding data, locking mechanisms when according to modification data avoid moving to the data setting resource lock in memory with thisIt is carried out using, it is ensured that the overall stability of business by business during except data.
