Description
Technical field
The present invention relates to computer realm, particularly relate to a kind of thread wakening control method and system.
Background technology
Thread is an entity in the process, the base unit of independently being dispatched and assigning by system, thread oneself does not have system resource, only has the requisite resource that partly is in operation, but it can share whole resources that process is had with other thread that belongs to a process together.Another thread can be created and cancel to a thread, can concurrently carry out between a plurality of threads in the same process.Because the mutual restriction between the thread causes thread to be in operation and presents discontinuity.That thread has is ready, block and move three kinds of basic status.Thread is single sequential control flow in the program, and it has well solved tight coupling and has shared parallel processing behavior on the multiprocessor architecture of main memory.The thread dormancy is meant that thread is in can not running status, is waiting to fix time or incident is resumed operation after activating again.
Existing system triggers carries out the bottom service thread, and dual mode is generally arranged:
A kind of is that passive type triggers execution: when the external world reaches certain condition, trigger and carry out service thread, to carry out required service.
Another kind is that active triggering is carried out, and is set at interval regular time, after the time of every interval appointment, all can go to trigger service thread, to carry out required service.
Above described two kinds of modes of trigger carrying out the bottom service threads following deficiency is arranged:
Trigger execution for passive type: need the external world to reach certain condition at every turn, could trigger and carry out service thread, controlling of active can't be accomplished by system, this mode, only being suitable for system does not need to regulate fully, only carry out the passive simple scenario of calling, under most complicated business scenes, all can not satisfy professional demand.
Carry out at interval active triggering of regular time is set, system is back, interval triggering service thread initiatively at the appointed time.Though this mode system obtains initiatively, but it is often reasonable not enough, when the triggering of service thread is not very regular, having needs the service thread that triggers many especially in certain time period, and in certain time period, need the service thread that triggers especially after a little while, the mode that adopts this set at interval active triggering of regular time to carry out service thread can not well satisfy, and is special, triggering service thread can cause system resource in few time period a large amount of wastes.In real business scenario,, go to trigger service thread at different time often along with different conditions.Especially work as system and relatively pay close attention to for performance, when perhaps service thread compared consumes resources, the mode of this Fixed Time Interval dispatch service thread was also unreasonable, has wasted a large amount of system resource.

For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
First embodiment provided by the invention with reference to Fig. 1, shows the process flow diagram of a kind of thread wakening control method of the present invention, comprising:
Whether step 103, detection have waiting task.
Behind the thread wakening, system detects whether pending task is arranged, and enters step 104.
Step 104, when having detected waiting task, then carry out described waiting task.
After having detected waiting task, finish the processing of described waiting task, enter step 105; Do not have pending task if detect, then directly enter step 105.
When after the processing of finishing waiting task or detect do not have waiting task after, thread is put dormant state, the time interval of thread dormancy is changed to the time interval that dynamic weighting is provided with.The dormancy time of described thread can be provided with according to the Automatic Frequency weighting of waiting task, can be arbitrary time span, also can be certain Fixed Time Interval, and perhaps its multiple can also be into time interval of the number of permutations.The present invention does not limit it.
Second embodiment provided by the invention with reference to Fig. 2, illustrates the process flow diagram of a kind of thread wakening control method of the present invention, comprising:
Some are relatively expended the service thread of system resource, if described thread is in running status always, then can cause a large amount of wastes of system resource, for conserve system resources, when described service thread when not having waiting task, allow it be in dormant state, promptly described line is in can not running status, waiting to fix time or incident is resumed operation after activating again, preferably waking operation up in embodiments of the present invention through after the time interval of dynamic weighting.Specifically waking mode up will describe in detail in step 203,204.
Whether step 202, detection have waiting task.
Behind the thread wakening, detect whether waiting task is arranged, have waiting task then to enter step 203; No waiting task then enters step 204.
When having detected waiting task behind the thread wakening, then finish the processing of described waiting task, as the transmission of message, the transmission of mail.After all waiting tasks are all finished, when thread is in idle condition, be conserve system resources, putting described thread is dormant state, being in can not running status.For the sleep interval that makes thread has memory function, the dormancy time of scientific and rational arrangement thread, reach thread in the waiting task short purpose of dormancy time for a long time, the embodiment of the invention preferably take to reset after thread the is finished waiting task dormancy time of described thread is minimum unit time interval Δ t.Also be that thread dormancy time at this moment is the shortest, thereby can not cause the low of task treatment effeciency, guaranteed the timely processing of task, can not influence the efficient that task is handled, reasonably solved the contradiction that economizes on resources with the efficient processing of task because of economizing on resources.
The time interval sum Δ at of step 204, nearest twice dormancy of calculating, the time interval of putting the thread dormancy is Δ at.
Behind thread wakening, system detects when not having waiting task, shows that the waiting task amount is few in this time period.At this moment, dormancy time is long after a little while at waiting task in order to reach thread, the purpose of conserve system resources, the dormancy time that the embodiment of the invention is preferably taked has memory function, also promptly when detect do not have waiting task after, then calculate the time interval sum Δ at of nearest twice dormancy, the sleep interval of thread is changed to the time interval sum Δ at of nearest twice dormancy with this moment, behind thread dormancy Δ at, wake detection again up whether waiting task is arranged, have and then enter step 203, no waiting task then enters step 204, so always circulation.
According to above description to the embodiment of the invention, can know, for service thread, when its waiting task for a long time, handle at every turn then that the dormancy time of replacement thread is minimum unit time interval Δ t behind the waiting task, the present invention can be provided with arbitrarily to described minimum unit time interval Δ t without limits as required, as 0.5s, 1s, 2s, 5s.......Assurance can both high efficiencyly be handled all waiting tasks at every turn like this.When not having waiting task, then the each dormancy time of thread is nearest twice dormancy time sum, the dormancy time of thread has memory function like this, when not having waiting task, the dormancy time of thread is more and more longer, the system resource of waste is fewer and feweri, thereby has reasonably solved waste system resource and the not high contradiction of Processing tasks efficient.
Further, if thread is dormancy for the first time, then the time interval sum Δ at of described nearest twice dormancy is exactly the minimum unit time interval Δ t that presets.
If when thread was dormancy for the second time, the time interval of described nearest twice dormancy all was the minimum unit time interval Δ t that presets, the time interval sum Δ at of described nearest twice dormancy is 2 times of minimum unit time interval Δ t.
With instantiation the embodiment of the invention is carried out a detailed introduction below, with reference to Fig. 3.
It is 1s that minimum unit time interval Δ t is set, and waiting task is the transmission of message, after thread is waken up, whether have More-Messages-To-Send send, if detected message to be sent, then send and all wait to send out message if detecting, send all wait to send out message after, replacement thread dormancy time is 1s.Do not have message to be sent if detect after thread is waken up, then the dormancy time of thread is nearest twice dormancy time sum, if thread is dormancy for the first time, then the dormancy time of described thread is 1s.Be waken up behind the thread dormancy 1s, detect whether remain message once more, if having, then send all message, the dormancy time that sends back replacement thread is the minimum unit time interval, i.e. 1s.If there is not message to be sent, then the dormancy time of thread is changed to 2s.So circulation is gone down, easily as learning: if message to be sent is all arranged at every turn, then the dormancy time of each thread all is the minimum unit time interval, be 1s, do not have message to be sent if all detect always, then the dormancy time of thread is followed successively by 1s, 2s, 3s, 5s, 8s, 12s, 20s, 32s......, the dormancy time that is each thread all is the dormancy time sum of nearest twice thread, like this, when not having message to be sent, the dormancy time of thread has memory function.Detected message to be sent after certain thread dormancy is waken up after, then the dormancy time of replacement thread is the minimum unit time interval, i.e. 1s after sending message to be sent.Behind thread dormancy 20s, detected message to be sent, then the dormancy time of thread is not 32s next time, but 1s, thereby has guaranteed to send the efficient of message, can be because of by sacrifice efficient and conserve system resources.The saving and the efficient contradiction that sends message of system resource have reasonably been solved.

Some are relatively expended the service thread of system resource, if described thread is in running status always, then can cause a large amount of wastes of system resource, for conserve system resources, when described service thread when not having waiting task, allow it be in dormant state, promptly described line is in can not running status, waiting to fix time or incident is resumed operation after activating again, preferably waking operation up in embodiments of the present invention through after the time interval of dynamic weighting.Specifically waking mode up will describe in detail in step 403,404.
Whether step 402, detection have waiting task.
Behind the thread wakening, detect whether waiting task is arranged, have waiting task then to enter step 403; No waiting task then enters step 404.
When having detected waiting task behind the thread wakening, then finish the processing of described waiting task, as the transmission of message, the transmission of mail.After all waiting tasks are all finished, when thread is in idle condition, be conserve system resources, putting described thread is dormant state, being in can not running status.For the sleep interval that makes thread has memory function, the dormancy time of scientific and rational arrangement thread, reach thread in the waiting task short purpose of dormancy time for a long time, the embodiment of the invention preferably take to reset after thread the is finished waiting task dormancy time of described thread is minimum unit time interval Δ t.Also be that thread dormancy time at this moment is the shortest, thereby can not cause the low of task treatment effeciency, guaranteed the timely processing of task, can not influence the efficient that task is handled, reasonably solved the contradiction that economizes on resources with the efficient processing of task because of economizing on resources.
The time interval sum Δ at of step 404, nearest twice dormancy of calculating.
If the time interval sum Δ at of described nearest twice dormancy of step 407 is not more than described default maximum time during interval delta T, the time interval of then putting the thread dormancy is Δ at.
According to above description to the embodiment of the invention, can know, for service thread, when its waiting task for a long time, handle at every turn then that the dormancy time of replacement thread is minimum unit time interval Δ t behind the waiting task, the present invention can be provided with arbitrarily to described minimum unit time interval Δ t without limits as required, as 0.5s, 1s, 2s, 5s.......Assurance can both high efficiencyly be handled all waiting tasks at every turn like this.When not having waiting task, then the each dormancy time of thread is nearest twice dormancy time sum, the dormancy time of thread has memory function like this, when not having waiting task, the dormancy time of thread is more and more longer, the system resource of waste is fewer and feweri, and be provided with one maximum time interval delta T, when the time interval of nearest twice dormancy sum Δ at greater than described default maximum time during interval delta T, the dormancy time of thread of then resetting is the minimum unit time interval, avoided like this since thread for a long time dormancy and can not be waken up, detect waiting task, can not cause the low of Processing tasks efficient.
Further, if thread is dormancy for the first time, then the time interval sum Δ at of described nearest twice dormancy is exactly the minimum unit time interval Δ t that presets.
If when thread was dormancy for the second time, the time interval of described nearest twice dormancy all was the minimum unit time interval Δ t that presets, the time interval sum Δ at of described nearest twice dormancy is 2 times of minimum unit time interval Δ t.
With instantiation the embodiment of the invention is carried out a detailed introduction below, with reference to Fig. 5.
It is 1s that the minimum unit time interval is set, waiting task is the transmission of message, maximum time, interval delta T was 30s, after thread is waken up, whether have More-Messages-To-Send send, if detected message to be sent, then send and all wait to send out message if detecting, send all wait to send out message after, replacement thread dormancy time is 1s.Do not have message to be sent if detect after thread is waken up, then the dormancy time of thread is nearest twice dormancy time sum, if thread is dormancy for the first time, then the dormancy time of described thread is 1s.Be waken up behind the thread dormancy 1s, detect whether remain message once more, if having, then send all message, the dormancy time that sends back replacement thread is the minimum unit time interval, i.e. 1s.If there is not message to be sent, then the dormancy time of thread is changed to 2s.So circulation is gone down, easily as learning: if message to be sent is all arranged at every turn, then the dormancy time of each thread all is the minimum unit time interval, be 1s, do not have message to be sent if all detect always, then the dormancy time of thread is followed successively by 1s, 2s, 3s, 5s, 8s, 12s, 20s, 32s......, the dormancy time that is each thread all is the dormancy time sum of nearest twice thread, like this, when not having message to be sent, the dormancy time of thread has memory function.Detected message to be sent after certain thread dormancy is waken up after, then the dormancy time of replacement thread is the minimum unit time interval, i.e. 1s after sending message to be sent.Detecting when does not always have message to be sent, and when thread carried out the 8th dormancy, because described time that will dormancy surpasses 30s at interval of default maximum time, then the 8th of thread the dormancy time was not 32s, but the minimum unit time interval, i.e. 1s.Avoided like this since thread for a long time dormancy and can not be waken up, detect waiting task, can not cause the low of Processing tasks efficient.
