Specific implementation mode
In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with the application reality
The attached drawing in example is applied, technical solutions in the embodiments of the present application is clearly and completely described, it is clear that described implementation
Example is merely a part but not all of the embodiments of the present application.Based on the embodiment in the application, this field is common
The every other embodiment that technical staff is obtained without creative efforts should all belong to the application protection
Range.
For convenience those skilled in the art understand that technical solution provided by the embodiments of the present application, below first to technical solution
The technological accumulation and inheritance of realization illustrates.Common thread can only once execute an event, and thread will move back after handling part of finishing
Go out.But a kind of mechanism that thread can be allowed to handle event at any time and do not exit is needed in many application scenarios, it is typical to apply
Scene such as voice input monitor, the monitoring etc. of various hardware events (such as touching screen, rock mobile phone).In such application
In scene, user's incoming event is the process constantly repeated, and thread is only configured to cyclically execute monitoring task, can
The incoming event of user is handled in time.The above problem can be well solved using event loop (Event Loop) mechanism.
So-called event loop mechanism refers to the process of that the main thread of application repeatedly obtains message from message queue, executes message,
In, every message in message queue corresponds to an event.At the typical event loop mechanism such as event of Node js
Reason, the RunLoop operating mechanisms etc. of the message loop in Windows operating system, iOS.That is, being followed just because of event
The presence of ring mechanism can make App constantly run, and otherwise, APP runs will be immediately finished at the beginning.
The characteristics of repeating task in event loop mechanism often leads to the interim card of application, and is collapsed caused by interim card
It is one of the problem of most influencing user experience in applying and the maximum pain spot of application developer, so quickly identifying application card
, orientation problem root be best one of solution.Usually, it applies after reaching the standard grade, for developer and O＆M people
For member, the framework of application, the executive condition of program code are all a black boxs, can not perceive user and use the true of application
Impression can not be predicted using that whether interim card can occur, can't see how the specific data of business execute on earth, standard of more having no way
The reason of really navigating to using interim card occurs.
Interim card of the main thread in single cycle is calculated using several material time nodes in event loop system
Time can well solve the above problem.Before the embodiment for introducing interim card detection provided by the present application, introduce first
The execution step of event loop mechanism, it can be seen from the above, the otherness of platform leads to the realization method of event loop mechanism not to the utmost
It is identical, in order to clearly show the details of this programme, therefore it is without limitation the thing based on iOS by event loop mechanism construction
The part circulatory system, still, one of skill in the art will understand that, the event loop mechanism of the application can be based on any behaviour
Make the event loop mechanism of system.
In iOS, when an application is activated, correspondingly, operating system can create one and be applied relatively with described
The host process answered, the main thread are used to execute the task in the application.While creating the host process, the main line
Journey is also started immediately.In iOS, the main thread of the event loop system and application has one-to-one relationship.Fig. 1 is existing
There is the execution flow chart of the event loop system based on iOS in technology, as shown in Figure 1, in the implementation procedure of event loop system
In, it is related to the objects such as timer, the source (source1) based on port, the source (source0) for being not based on port, observer.Under
Effect and performed task of the above-mentioned several objects played in the event loop system of iOS are introduced respectively in face.
Wherein, the timer may include time-based trigger, for example, the trigger include time span and
It adjusts back (function pointer).The timer is added to event loop system, the event loop system can register correspondence
At the time point of time span, when reaching at the time point, event loop system can be waken up to execute the institute in timer
State readjustment.
The place that source is generated as event can be divided into two kinds of source0 and source1.Wherein, source0 cannot be led
Dynamic trigger event, and source1 can be used for mutually sending message by kernel and other threads, and being capable of active main thread
(if event loop system is in a dormant state).
The observer can include readjustment (function pointer), when the state of event loop system changes, observation
Person can receive the state change of event loop system by the readjustment.The observer can be used for tracking following things
Part：Event, the event loop system of the entry event circulatory system will handle the event of timer, event loop system will stop
The event etc. that event, the event loop system that event, the event loop system of dormancy are waken up will exit.
As shown in Figure 1, the implementation procedure of event loop system can be divided into 7 stages, wherein the stage in stage 2- 6 is set
It is set to the process that cycle executes.After the source0 events in the stage that handled 3, event loop system is begun listening in applying
Source1 events whether occur, if listening to source1 events, skip phase 4 and stage 5, go in the stage 6
Execute the source1 events received.From the process that the process in stage 4 to stage 5 is waiting event, at this point, event loop system
System in a dormant state, when source1 events occur, the source1 events can the active wake events circulatory system, allow
Event loop system executes the event received.It is based on above-mentioned event loop system, can be installed in iOS
It applies and rests when user does not operate, and the operation for the user that can make an immediate response when user's operation.
Based on above-mentioned event loop system, a kind of method that interim card is applied in detection is proposed in the prior art, Fig. 2 is existing skill
The method flow diagram that interim card detects in art, as shown in Fig. 2, one in 7 execution stages that event loop system can be obtained
Crucial moment, the crucial moment can be subject thread (such as main thread) event loop system in single cycle from
Tm at the time of wake-up in suspend mode.The specific method that moment tm is waken up from suspend mode that obtains can refer to method stream shown in Fig. 3
Cheng Tu judges whether the event loop system calls out from suspend mode as shown in figure 3, can monitor event loop system
It wakes up, if the determination result is YES, then obtains tm at the time of the event loop system wakes up from suspend mode；Otherwise, judge the thing
Whether the part circulatory system enters dormant state.If it is determined that the event loop system enters dormant state, then the event is followed
Tm is set as 0 at the time of loop system wakes up from suspend mode.As shown in Fig. 2, obtaining the event loop system single cycle mistake
In journey after tm at the time of wake-up in suspend mode, period ctm-tms of the moment tm apart from current time ctm is calculated.If described
Moment tm is not equal to 0 and ctm-tm >=interim card activation threshold value, it is determined that the target process is in interim card state.
In conjunction with the above-mentioned description to being detected in the prior art using interim card method, it is found that due to detecting whether to occur
The starting time of interim card is the stage 5 in Fig. 1, and the end time is the stage 4 in Fig. 1, and entire detection process has ignored the stage 4 and arrives
At least there are following two problems in the waiting period in stage 5：
First, in a typical application scenarios, for certain Nanjing user during using certain APP, the user is at 1 point
Ceaselessly browsing pictures in clock, and the download of picture needs to send network request to server, then the client of the user exists
In this 1 minute period ceaselessly network request is sent to server.It can be found that the user is in the normal use APP,
But if using detection in the prior art using the method for interim card, it is likely that determine the APP within this 1 minute period
Interim card occurs.If (access page when being such as back to historical time point of taking emergency measures is arranged after determining that interim card occurs for APP
Face), it will be very bad experience for users.
With reference to above application scene explanation, problem existing for interim card is applied in detection in the prior art.As shown in Figure 1,
It listens to after client in the stage 3 sends out network request (i.e. source1 events), event loop system will skip phase 4
With the stage 5, then execute stage 6 the step of.Problems with will so be will appear：If being waken up from suspend mode in the record stage 5
Moment is tm, and hereafter, event loop system listens to the network request (i.e. source1 events) that client is sent out incessantly,
During then handling network request in the stage 6, stage 4 and stage 5 will not all be performed always.If at this point, using existing
It is more than interim card activation threshold value that technical method, which can be calculated and wake up period ctm-tms of the moment tm apart from current time ctm,
Judgment rule according to fig. 2 then erroneously determines that interim card occurs for subject thread.But there is no occur for the actually described subject thread
Interim card, the subject thread are steadily run from stage 3 to the stage 6 always.
Second, interim card detection in the prior art has ignored the sleep procedure in stage 4 to stage 5, but in a practical situation,
During between stage 4 to the stage 5, event loop system is not constantly in dormant state.Fig. 4 is thing in the prior art
The part circulatory system is in work flow diagram when sleep procedure, as shown in figure 4, working as the event loop system in a dormant state
When, it can monitor and default interface operation event whether occurs be handled described pre- if listening to the default interface operation event
If interface operation event.After the event loop system has handled the default interface operation event, restore to dormant state.
Pass through the flow chart described in Fig. 4, it is found that although the default interface operation event cannot by the event loop system from
It is waken up in dormant state, but the event loop system handles the default interface operation event in sleep procedure really.
So, event is handled in sleep procedure it can also happen that interim card, and interim card detection method in the prior art has ignored event
The circulatory system handles the process of event in sleep procedure, thus may omit the part interim card fallen in the event loop system
The detection of phenomenon.
It is directed to the phenomenon that above-mentioned interim card for applying interim card detection method to occur in the prior art is judged by accident, interim card is failed to judge, this
Application proposes a kind of detection method using interim card, can accurately judge to apply whether interim card occurs.It is right below in conjunction with the accompanying drawings
