The inventors discovered that process exits before destruction due to having resource waiting, process under some scenes
The process exited may even result in process more slowly and can not exit.For example, process 1 executes the certain operations of file system and needs
Some memories are distributed, Memory Allocation unsuccessfully enters Memory recycle and finally starts low memory management service clean up process 2, process 2
The operation of some file system is had to carry out when thoroughly exiting, these operations can be applied locking A.If process 1 holds this just
A is locked, is mutually waited here, deadlock is formed, final process 2 cannot exit therefore can not discharge memory, and 1 Memory Allocation of process encounters
Memory anxiety cannot also alleviate well.
In order to solve the above-mentioned technical problem, a kind of method for recovering internal storage, Ke Yiying are provided firstly in the embodiment of the present disclosure
The application scenarios for being discharged and being optimized for the memory to terminal, terminal herein include any electricity for being equipped with Android system
Sub- product, such as mobile phone, tablet computer etc..With reference to shown in Fig. 1, which may include step S110 and step
Rapid S120, in which:
In step s 110, if detecting the Memory Allocation operation failure to default process, low memory management clothes are triggered
Business carries out cleaning operation to target process；
In the step s 120, if detecting, the cleaning operation terminates, and carries out to the memory pages of the target process
Reclaimer operation, and continue to carry out Memory Allocation operation to the default process by the reclaimer operation.
In the method for recovering internal storage provided in the embodiment of the present disclosure, on the one hand, due to withouting waiting in default process
Resource information discharges automatically, but is recycled by the memory pages to target process so that target process automatically exits from, into
And it is default process storage allocation, it completes and exits target process and to preset the operation of process storage allocation, avoid pre-
If the case where process and target process form endless loop caused by mutually waiting and limit, improves Memory recycle and memory point
The efficiency matched.On the other hand, it due to directly carrying out reclaimer operation by the memory pages to target process, and is grasped according to recycling
Work continues to carry out Memory Allocation to default process, therefore can accurately determine to be cleared up during carrying out Memory Allocation
Process improves the accuracy and relevance of internal memory optimization.In another aspect, due to that can clear up in time target process and be
Default process storage allocation space, therefore it is capable of the situation of rapid recovery memory anxiety, improve system stability.
Next, the method for recovering internal storage in the embodiment of the present disclosure is specifically described referring to figs. 1 to Fig. 3.
In step s 110, if detecting the Memory Allocation operation failure to default process, low memory management clothes are triggered
Business carries out cleaning operation to target process.
In the embodiment of the present disclosure, default process can be any process either launching process, this sentences launching process and is
Example is illustrated.Launching process can be process, or file storage etc. needs the operation of storage allocation, this sentences process
For be illustrated.In the embodiment of the present disclosure, launching process, which is specifically as follows, to be not yet in operating status but will start to transport
Capable process, such as the process newly opened.Launching process can be various types of processes, and can be in response to the operation of user
And it opens.For example, launching process can be the biggish games A of a committed memory.Memory Allocation operation refers to open
The method of dynamic process distribution memory space.Memory Allocation operation has static memory distribution and two kinds of dynamic memory distribution.Memory point
It can once be executed with operation, or it is performed a plurality of times, and the memory of Memory Allocation operation distribution can be identical every time, it can also
With difference, herein without limitation.For example, the preset threshold of system setting is 200MB, and the free memory of current system is
210M (does not trigger low memory management service), starts a big game program at this time, saves as the interior of 200MB in distribution
It deposits.
If current free memory is greater than the committed memory of default process in system, Memory Allocation operation can be at
Function；If current free memory is less than the committed memory of default process in system, the Memory Allocation of default process is operated
It may will fail.
In the embodiment of the present disclosure, if the currently available memory of system be less than default process needed for committed memory, can be with
Think the Memory Allocation operation failure to default process.In addition to this, due to Memory Allocation failure caused by other reasons
Within the protection scope of the embodiment of the present disclosure.In the case where memory batch operation failure, if to be embodied as default process
The purpose of storage allocation then can carry out cleaning operation to the process in system.It should be noted that process herein refers to
The process being currently running in system.Android system is provided with the process of following classification: foreground process, visible process, secondary clothes
Business, background process, content provider and null process.The priority of above-mentioned process of all categories is successively from high to low, and all kinds of
The process of type is provided with corresponding memory threshold in advance.Based on this, for that can be for the process of low memory management service cleaning
The whole processes run in system either Partial Process.Partial Process can be either different excellent for the process of equal priority
The process of first grade, is not construed as limiting herein.
When judging the Memory Allocation operation failure of default process, target process can be cleared up.Target process can
With associated with resource information, can not also be associated with.The quantity of target process can be one, or it is multiple, and target
The quantity of process can be determined according to the committed memory of default process and the free memory of system.Believe in target process and resource
In the associated situation of manner of breathing, target process can be process, that is, association process associated with default process, and target process can be with
It is identical as the type of default process, it can also be different, be not construed as limiting herein.Target process may be association process and any
The process of type, is not construed as limiting herein.
Wherein, target process is associated to default process refers to that default process is related by resource information to target process
Connection.Resource information can be exist only in default process (process of memory to be allocated), and resource information be target process (to
Recycle memory process) needed for resource, such as can by be present in default process but target process exit when it is required
Resource.Resource information can be for example lock either other kinds of resource, this is illustrated for sentencing lock.Lock is concurrent
One of process synchronization mechanism.For lock other than allowing critical zone mutual exclusion to execute, the thread that release can also be allowed to lock is same to obtaining
The thread of a lock sends message etc., to avoid conflicting with each other between process, prevents multiple processes from reading while write in a certain piece
Deposit region.In the case where target process is not associated with resource information, target process can be any appropriate process.The disclosure
In embodiment, the technical issues that need to address an are as follows: process possesses lock but only Memory Allocation success could discharge lock, separately
It could be process storage allocation space that one process, which exits needs and locks, thus target process can by resource information with preset into
Journey is associated.Based on this, by target process include with default process by the corresponding association process of resource information for carry out
Explanation.
In the embodiment of the present disclosure, in the case where memory batch operation failure, then low memory management service can be activated.In
After activating low memory management memory, it can be cleared up by the process in low memory management service acquisition system.It is general and
Speech, for low memory management service, according to the priority of process and the size of committed memory to determine whether the process of kill.
That is, the priority according to each process selects from low to high, in the case where All factors being equal, preference will be give to grade, the maximum process of EMS memory occupation is selected
It kills.Method in the embodiment of the present disclosure directly carries out cleaning operation to target process, can reduce the model of the process to be cleared up
It encloses, improves the accuracy rate of determining clean up process.
On this basis, in this example embodiment, however, it is determined that gone out target process, then can have been taken by low memory management
It is engaged in executing cleaning operation to determining target process.Cleaning operation herein refers to stopping either closing target process, with
So that it is no longer on operating status or target process is allowed to be in background operation state.Cleaning operation is being executed to target process
Afterwards, the occupied memory headroom of the target process can be discharged, thus the situation of rapid recovery Installed System Memory anxiety, in order to
It is default process storage allocation space in the case where cleaning target process.
In the step s 120, if detecting, the cleaning operation terminates, and carries out to the memory pages of the target process
Reclaimer operation, and continue to carry out Memory Allocation operation to the default process by the reclaimer operation.
In the embodiment of the present disclosure, if detecting terminates the cleaning operation of target process, in target process and preset
Process passes through in the associated situation of resource information, can memory pages directly to target process carry out reclaimer operation.Herein
The memory pages of target process refer to the page quickly exited for controlling target process.Pass through the memory to target process
The page carries out reclaimer operation, target process can be made quickly to exit, and just moves back after discharging resource information without waiting for default process
Out, improve target process exits efficiency, avoids prolonged waiting process between default process and target process, improves
The efficiency of Memory Allocation and the efficiency of Memory recycle, and the Memory recycle being completed at the same time between the different processes of mutual restriction
And Memory Allocation.
Specifically, memory pages can be anonymous page, or file page, this is illustrated for sentencing anonymous page.
Wherein, anonymous page refers to the memory distributed by dynamic memory distribution function, and anonymous page can be with the occupancy of target process
Memory is consistent.Anonymous page belongs to the anonymous linear zone of some process, is mainly used for page exchange.For example, the User space heap of process and
All pages in storehouse are anonymous page.There is the page of background document to be known as anonymous page, such as heap, stack, data segment be not with file
There are pages for form, therefore can not exchange with disk file, but can be by dividing additional exchange partition on hard disk or making
It is swapped with swap file.File page refers to the memory distributed when reading and writing of files.
When memory pages are anonymous page, the detailed process for carrying out reclaimer operation to the memory pages of target process includes:
Judge whether the memory information of the default process meets preset condition, and according to judging result to described in the target process
Anonymous page carries out the reclaimer operation.The stream that the memory pages of target process are carried out with reclaimer operation is diagrammatically illustrated in Fig. 2
Cheng Tu mainly includes step S210 to step S230 with reference to shown in Fig. 2, in which:
In step S210, judge whether the memory information of the default process meets preset condition.If so, going to step
Rapid S220；If it is not, then going to step S230.
In this step, preset condition is for indicating whether the size of memory is enough.The memory information of default process can wrap
Include the committed memory of default process and the free memory of system.The memory information of default process meets preset condition and is understood that
The committed memory of the enough and default process of low free memory for system is little, specifically can with the committed memory of default process with
And size between the free memory of system indicates.For example, if the committed memory of default process is greater than the free memory of system,
And the part for being greater than the free memory of system is less than threshold value, then it is assumed that meets preset condition.If the committed memory of default process is big
In the free memory of system, and it is greater than the partially larger than threshold value of the free memory of system, then it is assumed that be unsatisfactory for preset condition.Its
In, threshold value can be lesser a numerical value, such as 20M etc..
In step S220, if the committed memory of the default process and the free memory of system meet the default item
The corresponding association process of the default process is then determined as target process, and carried out to the anonymous page of the target process by part
The reclaimer operation.
In this step, if the committed memory of default process is greater than the free memory of system, but in the occupancy of default process
The part for depositing the free memory greater than system is less than threshold value 20M, then it is assumed that meets preset condition.The quantity of target process can at this time
Think one, and the corresponding association process of default process can be determined as target process.For example, the occupancy of process 1
Inside saving as 200M, the free memory of system is 190M, although the free memory of system is less than the committed memory of process 1, two
Difference between person is less than 20M.Therefore it can choose corresponding as its by the associated association process of resource information with process 1
Target process.For example, process 2 must use the resource information in process 1 when exiting, thus can by process 2 as target into
Journey, and reclaimer operation is carried out to the anonymous page of process 2, so that process 2 exits.
It should be noted that since the free memory of the committed memory and system of presetting process meets the feelings of preset condition
Under condition, need completely to exit target process, so that it is no longer on operating status.Therefore it needs the anonymous page of target process
All recycling, in order to which target process exits.
In step S230, if the committed memory of the default process and the free memory of system are unsatisfactory for described preset
Condition then carries out reclaimer operation to the anonymous page of candidate process and association process.
In this step, if the committed memory of default process is greater than the free memory of system, but in the occupancy of default process
That deposits the free memory greater than system is partially larger than 20M, then it is assumed that is unsatisfactory for preset condition.When being unsatisfactory for preset condition, mesh
The quantity of mark process can be one or more.Specifically, the quantity of target process can according to the free memory of system with
The comparing result of difference and threshold value between the committed memory of default process and determine.The degree that difference is greater than threshold value is higher, mesh
The quantity of mark process is more.Such as it is the first estate (20M < A < 50M), the quantity of target process that difference, which is greater than the part A of threshold value,
It can be 1；If the part A that difference is greater than threshold value is the second grade (50M < A < 100M), the quantity of target process can be with
It is 2；The part A that difference is greater than threshold value is the tertiary gradient (100M < A < 200M), and the quantity of target process can be 3；Difference
Part A greater than threshold value is the fourth estate (200M < A), and the quantity of target process can be 5.When the quantity of target process is
At one, the corresponding association process of default process can be determined as to target process, in specific implementation and step S220
Step is identical, and details are not described herein again.When the quantity of target process is multiple, target process may include that default process is corresponding
Association process can also include candidate process.Candidate process can be default other corresponding association process of process, can also be with
For any process, it is not construed as limiting herein.
For example, the committed memory of process 1 is 260M, and the free memory of system is 190M, although system is available interior
Deposit the committed memory less than process 1, but difference between the two is greater than 20M and is inferior grade, the quantity of target process can be with
It is 2.One of process can be for, by the associated association process of resource information, another process can be with process 1
Candidate process.On this basis, the anonymous page of the association process for including in target process and candidate process can be returned
It brings drill to an end work, so that target process exits.
The flow chart that reclaimer operation is carried out according to association process and candidate process is diagrammatically illustrated in Fig. 3, with reference in Fig. 3
It is shown, it mainly include step S310 to step S330, in which:
In step s310, if the committed memory of the default process and the free memory of system are unsatisfactory for described preset
Condition then determines candidate's process from multiple processes；
In step s 320, institute is determined according to the default corresponding association process of process and the candidate process jointly
State target process；
In step S330, reclaimer operation is carried out to the anonymous page of the target process.
In the embodiment of the present disclosure, candidate process can according to preset rules from except carry out reclaimer operation association process it
The process chosen in outer multiple processes.Preset rules include the priority of process is minimum, committed memory of process is maximum,
Process includes that resource information and process are at least one of queue for clearance.Wherein, process includes what resource information referred to
It is that process exits and needs resource information.Process is in queue for clearance and refers to that process is in list for clearance, and successively
Process in the list is cleared up.For example, committed memory can be selected maximum from the minimum process of priority
Process is as candidate process.After determining candidate process, association process and candidate process can be determined as target process jointly.
The process that candidate process can either exit completely for the process of running background.When candidate process is running background
Process when, the process for carrying out reclaimer operation to the anonymous page of the candidate process in target process can be with are as follows: to it is described it is candidate into
Part anonymity page in journey carries out reclaimer operation by compress mode.It specifically, can be by recent (for example, one day, one week etc.)
Using being stored after less anonymous page compression, for example, becoming 50M after the anonymous page compression of 150M, when having use demand a next time into
Row decompression.When candidate process is the process to be cleared up (process to be killed either the process to be terminated), to target into
The process that the anonymous page of candidate process in journey carries out reclaimer operation can be with are as follows: recycles to all anonymous pages of candidate process
Operation.
After step s 130, the method for recovering internal storage further include: according to the reclaimer operation effect the target into
The anonymous page of journey determines target memory, and the target memory is distributed to the default process.For example, if recycling
The all anonymous page 100M of process 2, has in addition to this also recycled the part anonymity page of process 3, such as 20M, then target memory is
The sum of anonymous page and the anonymous page of process 3 of recycling of the process 2 of recycling, i.e. 120M may further be by target memory 120M
Distribute to default process.
Technical solution in Fig. 3 carries out reclaimer operation by anonymous page to target process, enable to target process and
When exit and releasing memory, in order to be default process storage allocation space, improve the efficiency of Memory recycle and Memory Allocation.
By the technical solution in the embodiment of the present disclosure, for preset the failure of process storage allocation (i.e. system it is available in
When depositing the committed memory for being less than default process), low memory management service can be activated to carry out cleaning operation to target process in time,
And reclaimer operation is carried out to the memory pages of target process at the end of cleaning operation, since target process can not continue to execute page
Exchange, so that target process be made to automatically exit from, avoiding target process must can just move back by the resource information in default process
Out the problem of, caused by also avoiding default process and can not being exited due to target process can not storage allocation space the problem of,
Avoid mutual restriction and the mutual restriction relation between default process and target process so that default process and target process it
Between no longer interdepend, improve independence.In addition, target process can be made quick by the memory pages of recycling target process
It exits, and then can be quickly default process storage allocation space, improve the efficiency of Memory Allocation and Memory recycle.Again,
Since the memory pages by recycling target process can realize the function of Memory recycle by timely clean up process, improves and be
The stability of system.
