In one embodiment, as shown in figure 3, providing a kind of process handling method, the present embodiment is applied in this way
It is illustrated for electronic equipment as shown in Figure 1.This method comprises:
Step 302, the first process for being in electronic equipment front stage operation is obtained.
First process indicates the process for being in front stage operation.There are multiple processes in operating status in electronic equipment, into
Journey (process) is program in computer about the primary operation activity on certain data acquisition system, is that system carries out resource allocation
It is the basis of operating system configuration with the basic unit of scheduling.The operation of one application (Application, abbreviation APP) is usual
It is to be embodied by the operation of relevant multiple processes.The process that foreground application is related to when running is the first process, is answered from the background
The process being related to when with operation is background process.The first process when electronic equipment can be obtained in foreground application operation.Often
A process can be used as a task (task) and execute, and forming task by the first process is foreground task, and background process is formed
Task be background task.
For each process in front and back operation, electronic equipment is provided with corresponding different priority, and different is excellent
First grade corresponds to different resource constraint degree.The higher process of priority is lower to the limited degree of resource workable for it.It is logical
Chang Di, the first process correspondence is provided with highest priority, and is relatively higher than the priority of background process.The same process,
Priority when in front stage operation and in running background is not necessarily identical.And the same background process, in difference
Priority under state is also not necessarily identical.For example, unified background process, at different times or when the first process difference,
The priority of the background process is also not necessarily identical.
Electronic equipment can obtain the first process according to preset frequency or according to the user operation instruction detected.It can
Selection of land can obtain the process identification (PID) of first process, and process identification (PID) is used for the corresponding process of unique identification, can be by presetting digit capacity
The combination of one or more of number, letter or other characters is constituted.For example, can be indicated with process identification (PID) " 0001 "
Process A indicates process B etc. with " 1234 ".
Electronic equipment can be in the process of front stage operation according to the operating status of itself come real-time update and be in backstage
The process of operation, optionally, the first process pool of settable corresponding first process and the background process pond of background process.
Process identification (PID) in the first process is added in first process pool, the background process is added in the process identification (PID) of background process
Chi Zhong, and when detecting that the process of front and back operation has variation, it is corresponding to update in first process pool and background process pond
Process identification (PID).For example, when detecting that process B becomes the first process by background process, it can be by the process identification (PID) of process B
" 1234 " move into the first process pool from background process pond.
In one embodiment, electronic equipment can be directed to each process, and corresponding foreground label is arranged or backstage marks, will
Process with foreground label is determined as the first process, or will there is the process of backstage label to be determined as background process.Pass through
The process with foreground label is obtained, to realize the acquisition to the first process.
Step 304, the second process is obtained, the second process is the background process that is relied on by the first process.
Relying on indicates that a process needs to be used in another or the data of multiple processes and could smoothly realize to this
The relationship of the execution of one process.There are two processes of dependence, the process of the process and dependence that are respectively relied on, electricity
Sub- equipment will test out using the background process relied on by the first process as the second process.Electronic equipment can be to the quilt detected
The background process setting that first process is relied on is corresponding to be relied on label, and obtains to have from background process pond and be relied on mark
The background process of note, using the background process as the second 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 B
Data be just able to achieve the execution to process A, at this point, process A be rely on process, process B is the second process.It can be with
Understand ground, the process of dependence is also possible to as the first process, and the second process may be background process.Electronic equipment can be from background process
It is detected in set, whether there is the background process relied on by the first process to inquire.
In one embodiment, before step 304, further includes: in detection background process set, if exist by first
The background process that process relies on, if so, using the background process as the second process.
Background process set, which refers to, is formed by set by background process, comprising transporting in backstage in the background process set
Capable process.Electronic equipment can traverse all background process, and detect whether there is the background process relied on by the first process,
Background process is detected with raising comprehensive.
In one embodiment, electronic equipment can be directed to all processes, record the dependence between each process, and
It records between the process with dependence, which is relying party, which is the side of being relied on.It, can be according to for first process
The dependence pre-established inquires the side of being relied on of first process, i.e., the background process relied on by first process.
Step 306, the priority of the second process is adjusted to the priority with the first process and is matched.
Optionally, for the second process inquired, electronic equipment can be adjusted its priority, so that adjusted
The priority of priority and first process matches.The priority of settable the second different process of electronic equipment and foreground are excellent
The matching relationship of first grade.According to the matching relationship, the corresponding priority for being suitable for the second process is obtained, and by the second process
Priority is adjusted to the priority, the resource constraint degree to the second process is reduced, so that the money that can be used the second process
The limited degree in source and the limited degree of the first process match.Wherein, foreground priority is the priority for first process that indicates.
In one embodiment, the priority to match with the priority of first process, can be and first process
The identical priority of priority.I.e. electronic equipment can adjust the priority of second process to the priority with first process
Identical priority, so that the limited degree for the resource that can be used to the second process is identical as the limited degree of the first process.
Above-mentioned process handling method, by obtaining the background process that is relied on by the first process, will by the first process institute according to
The priority of bad background process is adjusted to the priority to match with the first process.Due to usual first process priority most
The limited degree of height, corresponding workable resource is minimum, and the priority of background process is lower, to prevent background process from occupying
More resources, impacts foreground application.However it is relied in background process there is being relied on by the first process
Background process execution efficiency when, the first process can also be impacted.The application by adjusting the second process priority tune
The whole priority extremely to match with foreground priority, so as to reduce the limited degree for the resource that the second process can use, from
And improve the treatment effeciency of the second process.Since the treatment effeciency of second process improves, depended on to also improve
The treatment effeciency of first process of second process.
In one embodiment, after step 306, further includes: when the first process terminates the dependence to the second process,
By priority of the preferential level restoration of the second process to before adjusting.
Electronic equipment can detect whether the first process terminates the dependence to the second process, if so, by the excellent of the second process
Priority of the first level restoration to before adjusting.
First process is not the dependence being always maintained to the second process.When the first process do not needed to rely on again second into
When the data of journey, then the first process terminates the dependence of the second process.Electronic equipment can according to preset frequency to this first into
Dependence between journey and the second process is measured in real time, to detect whether the first process terminates to the second process
It relies on.Optionally, after first process that detects terminates the dependence of a certain second process, the preferential of second process can be restored
Grade, the i.e. priority by the preferential level restoration of second process to before adjusting.
Since the first process has been no longer dependent on the second process, thus the priority of the second process is restored, is mentioned
The resource that is relied on that height terminates dependence limits the use of available resources, so as to reserve more resources for the first process
It uses, further improves the treatment effeciency of the first process.
For example, priority 1 can be respectively set to priority 5 according to priority from high to low in electronic equipment, and totally 5 grades
Priority, the higher process of priority are lower to the limited degree of resource workable for it.When there are the second process A, second into
When journey A is in the state relied on by the first process, electronic equipment can be adjusted the priority of second process A by priority 4
, to improve the treatment effeciency of the second process A, make to priority 1 so that there is the second process A highest priority to be handled
Obtaining the first process can be improved the service efficiency of the data to the second process A, to improve the treatment effeciency of the first process；When detecting
When first process is over the dependence to second process A, since the first process is not depending on second process A, so
The priority of second process A is restored, the priority of second process A is adjusted by priority 1 to priority 4, with
Retain more available resources to use to the first process, further increases the service efficiency of the first process.
In one embodiment, before step 304, further includes: communicated when existing between background process and the first process
When mechanism, using the background process with communication mechanism as the second process.
Electronic equipment can detect background process set in, if exist with the first process have communication mechanism backstage into
Background process with communication mechanism is determined as the background process relied on by the first process by journey.
Interdepending between two processes is always built upon on the basis that they need to communicate with each other.In operating system
In, the interaction mechanism between process is broadly divided into synchronization mechanism and communication mechanism.Wherein, communication mechanism include socket,
Binder, shared drive etc..Two programs on network realize the exchange of data, this company by a two-way communication connection
The one end connect is known as a socket.Binder is a kind of inter-process communication mechanisms, provides remote procedure call function.In shared
Depositing exactly allows two incoherent processes to access the same logical memories, shared drive be the process that is currently running at two it
Between share and a kind of very effective mode of transmitting data, the memory shared between different processes are usually arranged for same section of object
Manage memory.
In one embodiment, when there are socket to communicate between background process and the first process, binder communication, memory
When shared or lock waits, determine that there are communication mechanisms between background process and the first process.
Optionally, electronic equipment can be detected whether to exist by any one or a few following mode and be had with the first process
The background process of communication mechanism:
(1) detect whether there is the background process that with the first process there is socket and/or binder to communicate；
(2) detect whether there is the background process that memory sharing is carried out between the first process；
(3) background process stayed in lock resource there are first process etc. is detected whether.
Electronic equipment can traverse background process, detect whether exist between the first process have socket and/or
The background process of binder communication, if so, the background process that will test out is as the second process.Also can detect whether exist with
The background process that memory sharing is carried out between first process, if so, the background process that will test out is also used as the second process.
In one embodiment, electronic equipment can setting be between the first process and background process in Binder driving
No there are the testing mechanisms of Binder communication, and are invoked at the testing mechanism being arranged in Binder driving, to detect and first
Process is there are the background process that Binder is communicated, and the background process that will test out is as the second process.
In one embodiment, electronic equipment can detect each lock resource, and lock resource includes thread lock, file handle, letter
Number etc..For each lock resource, it can detect whether that lock, which occurs, to be waited, i.e. lock resource waits.It, can when detecting that generating lock waits
Further detect whether the behavior waited occurs in the first process.If so, traversal etc. stays in above the lock resource
All background process, will test etc. the background process that stays in the lock resource be used as second process.
In one embodiment, lock monitoring resource module and excellent can be arranged in electronic equipment in the kernel spacing of operating system
First grade adjusts module, and lock monitoring resource module is embedded into the primary waiting interface of kernel.Pass through the lock monitoring resource mould
Block, detects thread lock, file handle, and signal etc. locks various lock resources, if waits, whether the behavior waited is hair
Life is on the first process, and if it is generation on foreground task, then the message that will test is sent to priority adjustment mould
Block.The lock resource all of the above background thread is stayed in by priority adjustment traversal etc., using these background process as the
Two processes.And module is adjusted by the priority and adjusts the priority of the second process to the priority to match.
In one embodiment, before step 304, further includes: when there are synchronous between background process and the first process
When mechanism, using the background process with synchronization mechanism as the second process.
Electronic equipment can also by call futex system call detection background process set in, if exist with first into
Journey have synchronization mechanism background process, by the background process with synchronization mechanism be determined as by the first process rely on backstage into
Journey.
In concurrent program design, each process must restrict the access of public variable, and this restriction is known as synchronizing.?
In operating system, the synchronization mechanism of User space (user mode) can be realized by calling futex system to call.Wherein, User space
Refer to unprivileged.Synchronization mechanism includes semaphore, mutual exclusion lock etc..It is detected and the first process when by futex system calling
There are when the background process of any one synchronization mechanism, the background process that can be will test is as the second process.
In the above method, by the detection to communication mechanism and/or synchronization mechanism between the first process and background process,
What be will test out has the background process of communication mechanism and/or synchronization mechanism as the second process with the first process, can be improved pair
The efficiency of the detection of second process.
In one embodiment, before step 306, further includes: the second process of detection, which is performed required resource, is
Otherwise the no corresponding maximum allowable resource of current priority for being greater than the second process, keeps second if so, thening follow the steps 306
The priority of process is constant.
Optionally, electronic equipment can further detect second process institute when executed after detecting the second process
The resource needed is enough.Wherein, required resource representation process be performed it is each when inscribe, the maximum money of required occupancy
Source.For every kind of priority, electronic equipment is provided with corresponding resource constraint degree, and the maximum of different resource constraint degree permits
Perhaps resource is different.I.e. different priority corresponds to different maximum allowable resources.Maximum allowable resource representation process is when each
Inscribe the maximum resource for allowing to be used.
Wherein, above-mentioned resource may include CPU, I/O file resource etc..Electronic equipment can detect second process, be in
In corresponding priority, whether confined maximum allowable resource is greater than that be performed be required resource, if so, illustrating to execute
Resource needed for second process is enough, it may not be necessary to be adjusted to its priority.Any one is provided needed for the second process
When source is less than the maximum allowable resource of corresponding type, then above-mentioned step 306 is executed.
Come using resource as memory for example, required memory is 20Mb when the second process executes, and second process
Locating priority it is corresponding it is maximum allowable in save as 15Mb, then determine second process be performed required resource be less than pair
The maximum allowable resource answered is adjusted the priority of second process to continue to execute step 306, thus realization pair
The adjustment of corresponding maximum allowable resource.
In one embodiment, when the second process is in the CPU usage limitation of frozen state or the second process less than the
When the CPU usage limitation of one process, execution, which adjusts the priority of the second process to the priority with the first process, to match
Priority.
Electronic equipment can detect whether the second process is in frozen state；And/or the CPU usage limit of the second process of detection
The CPU usage made less than the first process limits.
For every kind of process, corresponding process status is also recorded in electronic equipment, and process status includes frozen state and can
Operating status.Although indicating that process also exists when frozen state, but it is not allowed to run and account for the resources such as memory.It can run
State is to indicate the state of permission process operation.When second process that detects is in frozen state, then money needed for directly determining
Source is greater than maximum allowable resource, and executes step 306.It, can be further to the second process when detecting in operating status
CPU usage limitation is detected, by the CPU usage of the limitation of the CPU usage of second process and the first process limit into
Row compares, when detecting CPU usage limitation of the CPU usage limitation to the second process less than the first process, then equally
Resource needed for determining is greater than maximum allowable resource, and executes step 306.
In the above method, by being performed the current preference whether required resource is greater than the second process to the second process
The corresponding maximum allowable resource of grade is detected, when required resource is greater than corresponding maximum allowable resource, then by the second process
Priority adjust the priority to match to the priority with the first process, if required resource is enough, can need not carry out excellent
First grade adjustment, can reduce the operation of electronic equipment.
In one embodiment, the second process is relied on process and second including first and is relied on process；Second is relied on
Process is relied on process by first and directly relies on, and first, which is relied on process, is directly relied on or indirectly relied on by the first process.

When dependent process is waken up, determine that the first process terminates the dependence for being relied on process to second.
Electronic equipment detectable first is relied on whether process is waken up, if so, being relied on the preferential of process for second
Priority of the level restoration to before adjusting.
Optionally, the dependence between process includes directly relying on and indirectly relying on.For example, there are process A, process B,
This 4 processes of process C and process D.Process A depends directly on the data of process B, and process B depends directly on the number of process C again
According to, and process C also depends directly on the data of process D.That is the dependence between process A~D is a kind of dependence of chain type.At this point,
The dependence between adjacent processes in chain type dependence is to directly rely on, rather than the dependence between adjacent processes is closed
System is to indirectly rely on.That is process A depends directly on process B, process B depends directly on process C, process C depend directly on again into
Journey B.And process A indirectly depends on process C and process D, and process B also indirectly depends on process D.
