By above-mentioned framework, it can be achieved that process handling method in each embodiment of the application.
Fig. 3 is the flow chart of process handling method in one embodiment.As shown in figure 3, the process handling method includes step
Rapid 302 to step 308.Wherein:
Step 302, it if detecting the corresponding shutdown signal of target process, detects target process and whether is in and freeze shape
State.
Application program (Application, APP) refers to the software write in electronic equipment for certain application purpose,
Electronic equipment can realize the Demand and service to user by application program.For example, user can pass through game class application program
Game is played, video can also be seen by video class application program, music etc. can also be played by music class application program.Using
Program can be divided into foreground application and background application according to the state of operation.Foreground application refers to be set in electronics
The application program of standby front stage operation, foreground application can with foreground show and with user realize interact.It answers on backstage
Refer to the application program in the running background of electronic equipment with program, background application cannot generally be shown on foreground and with
Realize interactive process in family.
Generally, the application operating of application program is completed jointly by one or more processes (process), and process is
It is the program in computer about the primary operation activity on certain data acquisition system, is that system carries out the basic of Resource Distribution and Schedule
Unit.Meanwhile a process can correspond to one or more threads, thread is a single sequential control process in program,
It is a relatively independent, schedulable execution unit in process.Process may include foreground process and background process, foreground process
As in the process of electronic equipment front stage operation, background process is the process in electronic equipment running background.Electronic equipment can
To control the switching of foreground process and background process, foreground process can switch to running background, and background process can also be switched to
Front stage operation.Specifically, the management to process can be realized by process pool, can be stored in process pool it is one or more into
The corresponding process identification (PID) of journey.Process pool may include foreground process pond and background process pond, include foreground in foreground process pond into
Journey corresponding process identification (PID) includes the corresponding process identification (PID) of background process in background process pond.When detect foreground process and after
When platform running state of a process changes, process pool can correspondingly add or delete the process identification (PID) for generating variation.For example, into
The process identification (PID) of journey A is that " 0123 " can be by the process of process A when detecting that process A becomes foreground process by background process
Mark " 0123 " is removed from background process pond, and is added in foreground process pond.
In one embodiment, shutdown signal refers to the signal for initiating process shutoff operation.Generally, electronic equipment is answered
Shutdown signal can be initiated with the application program of layer, process can exit fortune according to shutdown signal after receiving shutdown signal
Row.After process exits, no longer resources such as the processor of occupied terminal and memory.By taking the terminal of android system as an example, terminal
Application program in application layer can be by calling android.os.Process.killProcess
(android.os.Process.myPid ()) method initiates shutdown signal to process to trigger.It is understood that this Shen
Please in process handling method is illustrated by taking Android operation system as an example, but the process handling method of the application is not
Be only limitted to realize in android system, can be applied in IOS (IPhone Operating System), Saipan,
In the operating systems such as Windows, MAC OS (Macintosh Operating System).
Step 304, if detecting, target process is in frozen state, and target process is thawed.
Specifically, process can be frozen, and the process in frozen state is not closed, not run temporarily only.
Can generally a kind of processing be carried out to frozen process in operating system, one kind being entered by the frozen process of function body control
Not interruptable sleep state.In this not interruptable dormant process, even if being waken up, also due to the function
The presence of body and be restored immediately in not interruptable sleep state.Therefore the process in frozen state can not receive signal,
Also signal can not be handled.That is, the process in frozen state is not take up processor resource and is run, still
Still the resources such as memory and the hardware of electronic equipment are occupied.Resource prioritization and limitation pipe in the local ccf layer of electronic equipment
Reason module can be marked state of a process, realized by corresponding label to the control of process frozen state, passed through
State of a process label is read it is known that whether process is in frozen state.
After initiating shutdown signal, the inner nuclear layer of electronic equipment can receive application program in electronic apparatus application layer
Then the shutdown signal judges whether process is in by reading resource prioritization and the limitation management module of local ccf layer
Frozen state.Initiate shutdown signal can be third party application, or system application.For example, user can
To need the process of killing by third party application selection, then by third party application to user it is selected into
Cheng Faqi shutdown signal.Electronic equipment can also killing according to operating condition automatic trigger to background process, work as background process
When meeting killing condition, the system application automatic trigger of electronic equipment initiates shutdown signal to the background process.
Step 306, shutdown signal is sent to target process.
If judging, target process is in frozen state, and electronic equipment can be carried out target process by local ccf layer
It thaws.Meanwhile shutdown signal can be sent to target process by the inner nuclear layer of electronic equipment.If send shutdown signal, target into
Journey is also in frozen state, then target process can not just receive the shutdown signal, then the shutdown signal will be added into
In the corresponding signal processing queue of target process.After target process is defrosted, target process can be from signal processing queue
Processing signal is obtained, and processing signal is handled.
With process identification (PID) and receiving process mark is sent in the signal transmitted in electronic equipment, then pass through transmission process
Identifier lookup sends the process of the signal, and the process for receiving the signal is searched by receiving process mark.Specifically, electronics is set
It is standby can according to the receiving process identifier lookup target process carried in shutdown signal, then the shutdown signal is sent to receive into
The corresponding target process of journey mark.
Step 308, if detecting, target process is defrosted, and closes target process according to shutdown signal.
After target process is defrosted, the target process after defrosting can be placed in one kind can not frozen state, place
In cannot be frozen again not the process of congealable state.After target process is defrosted, signal and right can receive
Signal handle.Then target process can obtain shutdown signal by signal processing queue, and be carried out according to shutdown signal
It closes.
The process handling method provided in above-described embodiment, when detecting the corresponding shutdown signal of target process, if inspection
It measures target process and is in frozen state, then target process thaws.And closing is believed by the target process after thawing
It number is handled.Target process is in frozen state immediately in this way, can also handle in time shutdown signal.It is provided in equipment
In the insufficient situation in source, target process can also receive in time and respond shutdown signal, with timely release device resource, guarantee to set
Standby operational efficiency improves the resource utilization of equipment.
Fig. 4 is the flow chart of process handling method in another embodiment.As shown in figure 4, the process handling method includes
Step 402 is to step 420.Wherein:
Step 402, the resources occupation rate of electronic equipment is obtained, and target process is obtained according to resources occupation rate.
In one embodiment, in the process of running, the resource for application processing is limited electronic equipment.Therefore,
Electronic equipment needs continuous releasing memory in the process of running, just can guarantee effective operation of application in this way.Resource refers to electronics
Software or hardware resource that equipment must be used when handling application affairs, such as memory, the hardware resource of electronic equipment etc..
Resources occupation rate refers to the resource occupation ratio of electronic equipment, generally refers to the ratio of occupied resource and whole resources, can
It is indicated in the form of through percentage.For example, equipment it is total in have 128GB, it is occupied in have 56GB, that
The resources occupation rate of the equipment can be expressed as memory usage, and obtained memory usage is 43.75%.
The corresponding relationship for pre-establishing the process identification (PID) of resources occupation rate and process obtains corresponding according to resources occupation rate
Target process mark obtains corresponding target process further according to target process mark.Resources occupation rate and process can also be established
Priority corresponding relationship, then corresponding target priority can be obtained according to the resources occupation rate of electronic equipment, and obtain
The corresponding target process mark of the target priority is taken, corresponding target process is obtained according to target process mark.For example, by electric
The memory usage of sub- equipment is divided into the three grades such as 20~40%, 40%~70%, 70%~100%, and process is divided into 1
Grade, 2 grades, 3 grades, 4 grades, five priority such as 5 grades, the importance of grade process is successively decreased from 1 grade to 5.Then memory usage is established
Corresponding relationship between the priority of process enables memory usage 20~40% corresponding 4 grades of process, 5 grades, memory usage
40%~70% corresponding 3 grades of process, 4 grades, 5 grades, corresponding 2 grades, 3 grades, 4 grades, 5 grades of the process of memory usage 70%~100%.It is false
If the memory usage in electronic equipment is 50%, then corresponding process priority is just 3 grades, 4 grades, 5 grades, then obtain preferential
Grade is 3 grades, 4 grades, 5 grades of process is as target process.
Above-mentioned corresponding relationship can be stored by way of list, and electronic equipment can be counted at interval of a period of time
First resource occupancy, and corresponding target process is read from the list according to the resources occupation rate that statistics obtains and is identified, so
Corresponding target process is obtained according to target process mark afterwards.For example, electronic equipment can be at interval of 5 minutes reading first resources
Then occupancy obtains corresponding target process according to resources occupation rate.
Step 404, shutdown signal is initiated to the target process of acquisition.
Shutdown signal can be initiated by third party application, can also be initiated by system application.The shutdown signal of initiation
In can be, but not limited to include send process identification (PID), receiving process mark etc. contents.Electronic equipment can pass through receiving process mark
Know and search target process, the shutdown signal is then sent to the target process.For example, function int send_ can be passed through
Sig_info (int sig, struct siginfo*info, struct task_struct*t) sends signal to target process.
Step 406, it if detecting the corresponding shutdown signal of target process, detects target process and whether is in and freeze shape
State.
Step 408, if detecting, target process is in frozen state, obtains that target process is corresponding to freeze duration,
In freeze duration and indicate time interval at the time of enter frozen state from target process to current time.
When process enters frozen state, electronic equipment is understood the time that record the process simultaneously enters frozen state, then real
When monitor the state of electronic equipment, after process exits frozen state, and time of frozen state can be exited by record the process simultaneously.
Electronic equipment can be managed each state of a process in this way, the corresponding state of process recorded by electronic equipment, can
With the state under reading process at various moments.Freeze duration be at the time of mark target process enters frozen state to it is current when
The time interval at quarter, in particular to from this enter frozen state at the time of to current time time interval.For example, process sheet
It is secondary enter frozen state at the time of for 12 points 02 second 10 minutes, current time be 12 points 10 seconds 14 minutes, then obtain freezing duration being just 4
Divide 08 second.
Specifically, electronic equipment can read the current state of target process, if target process is currently at frozen state,
Can then read in target process this at the time of enter frozen state, then obtain current time again, and freeze shape by entering
It calculates with current time at the time of state and corresponding freezes duration.For example, function can be passed through in android system
SimpleDateFormat (" yyyy-MM-dd hh:mm:ss ") obtains current time, then freezes further according to entering for reading
At the time of knot state, Lai Jiduan freezes duration.
Step 410, if freezing duration greater than duration threshold value, target process is thawed.
It is understood that freeze duration can reflect process this enter frozen state duration, if process is long
Between be not defrosted in frozen state, illustrate that the process is not in operating status for a long time, it is believed that the process is inessential
Process, then the process can be closed.Duration threshold value is the value for screening the duration of target process, can basis
It is set.When target process is when freezing duration greater than duration threshold value, it is believed that user or system are again started up the target
The probability is relatively small for process, then the target process can thaw, be then shut off；If the duration of freezing of target process is less than
Duration threshold value.Then think user or system be again started up the target process probability it is bigger, then can continue to keep the target
The current state of process.
For example, duration threshold value be 1 hour, if the duration of freezing of target process is more than 1 hour, can by the target into
Cheng Jinhang thaws, and then closes the target process after defrosting.Assuming that a length of 5 minutes when freezing of target process, then say
Bright target process enter frozen state when it is 5 minutes a length of, then it is assumed that user or system are again started up the probability of target progress
It is larger, then can continue to keep the state of the target process.
Step 412, shutdown signal is added in the corresponding signal processing queue of target process, wherein signal processing queue
In include one or more processing signals for being handled target process.
Each process may have a signal processing queue, and signal processing queue can be a stack space,
It include one or more processing signals for being handled target process in the signal processing queue, each processing signal
All it is used to indicate the processing to process.Specifically, the corresponding signal processing queue of process can be the chain being arranged in order
Formula queue can be described by a data structure.For example, can pass through in signal processing queue list
Sigpending data structure describes.It may include three numbers such as head, tail, signal in sigpending data structure
According to wherein head is used to be directed toward the next pointer of the processing signal of most end, signal for being directed toward first processing signal, tail
For describing the signal collection in the signal processing queue.
Step 414, if detecting, target process is defrosted, and obtains the corresponding signal processing queue of target process, according to
The signal initiation time is ranked up signal is handled.
When target process is in frozen state, target process can not receive signal, can not also handle signal.Mesh
The processing signal that mark process receives will be stored in the signal processing queue, then again to letter after target process is waken up
Number processing queue in processing signal handled.After target process is defrosted, target process can in the electronic device into
Row operation.Target process can obtain corresponding signal processing queue, and the processing signal in signal processing queue is initiated according to signal
Time is ranked up, and signal initiates the time that the time is initiation processing signal.The time can be generally initiated according to signal by elder generation
Sequence after is arranged signal is handled, then can preferentially obtain the processing signal of queue first place when processing
It is handled.Can also initiate the time according to signal be arranged processing signal to first sequence by rear, and processing when can
It is handled with preferentially obtaining the processing signal of tail of the queue.In the present embodiment, signal processing queue puts in order, and processing
Sequencing be not specifically limited.For example, including three processing signals, the corresponding signal hair of signal A in signal processing queue
Playing the time is 12:16, and the corresponding signal of signal B initiates the time as 13:22, and the signal C corresponding signal initiation time is 13:50.
Then handling putting in order for signal in signal processing queue can be for signal A, signal B and signal C.
Step 416, the processing signal in the signal processing queue after sequence is successively handled.
Generally, in order to avoid the omission of information, target process is after being defrosted, untreated place during freezing
Reason signal is handled, i.e., successively handles the processing signal in the signal processing queue after sequence.It is understood that
Target process can also not have to all handle the processing signal in signal processing queue, can only obtain after defrosting
Part processing signal is taken to be handled.Optionally, object acquisition place from the signal processing queue after sequence is initiated according to signal
Signal is managed, and the processing signal that will acquire is handled.Wherein, signal initiates the object that object refers to initiation processing signal.Example
Such as, can the processing signal initiated of processing system application, or only handle corresponding signal and initiate object and shutdown signal
Signal initiates the identical processing signal of object.
It in one embodiment, can also be according to the priority class of traffic of processing signal from the signal processing queue after sequence
Processing signal is obtained, and the processing signal that will acquire is handled.Wherein, the priority class of traffic indicates the important journey of processing signal
Sequence.For example, can be according to the type setting signal priority of processing signal, the signal priority of the corresponding processing signal of instant message
Grade is higher, and the corresponding priority class of traffic for handling signal of non-instant message is lower.Processing signal is obtained according to the priority class of traffic,
Target process be defrosted after only can processing signal higher to priority handle, save the resource of equipment.
Step 418, target process is closed according to shutdown signal.
Specifically, target process is closed according to shutdown signal, can be by the target process after target process is closed
Corresponding thread is all closed, to avoid there is zombie process.After target process is closed, target process can be arranged
For can not frozen state, can not be under frozen state, target process can not be frozen again, and target process is avoided to be again introduced into jelly
Knot state and the occupancy for leading to resource.Optionally, can also be arranged can not frozen state duration, closed from target process
Start timing at the time of closing, target process is set in the duration can not frozen state.It is excellent process can also to be established
The corresponding relationship of first grade and duration, general process priority is higher, and corresponding duration is shorter.I.e. according to target process
Process priority obtain corresponding duration, the then timing since the target process pent moment, when this continues
Setting target process in long can not frozen state.
Step 420, the dependent process for depending on target process is obtained, and dependent process is closed according to shutdown signal.
In one embodiment, relying on indicates that a process needs to be used in another or the data of multiple processes could be suitable
Benefit realizes the relationship of the execution to a process.There are two processes of dependence, the process being respectively relied on and according to
Bad process.For example, process A is relied on dependent on process B or process B by process A, i.e., expression process A needs to utilize process
The data of B are just able to achieve the execution to process A, at this point, process A is the process of process B of depending on, process B be by into
The process that journey A is relied on.Specifically, in the embodiment of the present application, dependent process just refers to is run dependent on target process
Process.
Dependence between process is not constant always, but real-time change.Electronic equipment can will be between process
Dependence recorded, after target process is closed, search from the dependence of record dependent on target process
Background process closes the dependent process as dependent process, and according to shutdown signal.Specifically, between two processes
It interdepends and is built upon on the basis that they need to communicate with each other.Therefore, the corresponding dependent process of target process is obtained
It include: the background process between acquisition and foreground process there are correspondence, as dependent process.In an operating system, process
Between interaction mechanism be broadly divided into synchronization mechanism and communication mechanism.
Wherein, communication mechanism includes Socket, Binder, shared drive etc..Binder communication is real in android system
A kind of existing efficient IPC (Inter-Process Communication, interprocess communication) mechanism, is a kind of client-
The communication structure of server (client-server).Client can define a corresponding proxy interface, client with server
When calling the method in proxy interface, the parameter of client can be packaged into a Parcel object by the method for proxy interface, so
Parcel object is sent to the driving of the Binder in inner nuclear layer by proxy interface afterwards.Server can be read in Binder driving
Then Parcel object is parsed and is handled, and processing result is returned by request data.Socket communication can be to two
Web application is communicatively coupled, to realize the data exchange of the application program on network.Specifically, between local process
Communication can carry out one process of unique identification by PID (Process Identity, process identification (PID)), but between network process
Communication has no idea to realize.And IP (Internet Protocol, the agreement interconnected between network) in network communications
