Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Referring to Fig. 1, it illustrates the flow of assembly operating method provided in an embodiment of the present invention, specifically includes following step
Suddenly:
Step S101:When receiving the startup order of caller transmission, host process obtains each respective group of component
Part identifies.
In the present embodiment, when caller needs invocation component, sent to host process and start order.When host process receives
During the startup order, the component mark of securing component.
Step S102:The host process creates each component and identifies each self-corresponding subprocess, and the host process
Start each subprocess.
Identified for each component, a subprocess is respectively created in host process.So, each component each corresponds to a son
Process, the subprocess are used to enter row data communication with each self-corresponding component.Compared with assembly operating mode of the prior art,
In the present embodiment, each component corresponds to a subprocess respectively, can improve the calling efficiency of component.
Also, host process creates after each subprocess and starts each subprocess.It can be seen that each subprocess is not independence
, it creates and started and is required to rely on host process.
Step S103:The host process is completed between the caller and target element using successful subprocess is started
Data communication;Wherein, the target element starts component corresponding to successful subprocess to be described.
Wherein, caller needs to call each component, and caller is sent to host process starts order, and then host process
Create and start each subprocess, and communicated using the data started between successful subprocess complete call program and component.
It is to be appreciated that such as fruit part subprocess and not actuated success, completion is only to start successful subprocess and respective corresponding component
Between data communication.Wherein, data communications packets include to component and send data, also include obtaining data at component.
In the prior art, when caller needs to call each component, completed using a single host process and all
The communication of component, if host process calls some component to fail, the collapse of host process can be caused, so as to which other groups can not be called
Part, operation stability are poor.Also, in this kind of method of operation, the calling of component is less efficient.However, in the present embodiment, master enters
Journey is that each component individually creates a corresponding subprocess, and start after the startup order of caller transmission is received
Each subprocess, and then communicated using the data started between successful subprocess complete call program and component.It can be seen that each
Component corresponds to a subprocess respectively, when malloc failure malloc occurs in some subprocess, can't influence other subprocess and component
Between data communication, improve the stability and efficiency of assembly operating.Meanwhile the present embodiment can be in a variety of systems
Run on platform, such as Linux or Window, system compatibility is preferable.
In the above-described embodiments, host process utilizes the tool that subprocess complete call program communicates with the data between target element
Body implementation can be it is following any one.
First, the host process triggering starts successful subprocess and enters row data communication, the host process with target element
Trigger the successful subprocess of startup and directly enter row data communication with the caller.
Specifically, the data between the independent complete call program of host process triggering subprocess and component communicate.That is, subprocess
After being triggered, directly as the data transfer intermediary between caller and component, that is to say, that caller directly passes through son
Process enters row data communication with corresponding component.As shown in Fig. 2 the data that subprocess obtains at component are sent directly to call journey
Sequence, or, caller directly sends data to subprocess, and subprocess is transmitted that data in component, is called so as to realize
Program and inter-module are in communication with each other.
Second, the host process triggering starts successful subprocess and enters row data communication, the host process with target element
Trigger the startup successful subprocess and row data communication is entered by the host process and the caller.
Wherein, host process is also identified oneself with invoked procedure.That is, host process triggering subprocess enters row data communication with component,
But subprocess needs to complete to communicate with the data between caller by host process.As shown in figure 3, subprocess obtains at component
Data need to be transferred to caller by host process, or, caller need using host process to subprocess send number
According to, and then subprocess transmits this data to component, realizes that caller communicates with the data of inter-module.
In both the above implementation, the first implementation host process is only responsible for creating and starting subprocess, and son enters
Directly carry out data transmission between journey and caller, efficiency of transmission is higher.Second of implementation sub-process only need to be to master
Process sends data, and need not enter row data communication with external call program, host process as each subprocess with
The intermediary of external call program interaction, each subprocess is hidden, caller need to only interact with host process, and one side enters
Journey security is higher, and on the other hand the method for calling of multiple subprocess is transparent for caller, and need not be improved
Caller.
In above-mentioned each embodiment, it is necessary to which the information created includes process name and parameter when creating subprocess.Wherein,
Process name is used to distinguish different processes, and parameter includes host address of process port, component model and process operation etc..Separately
Outside, the component in above-mentioned each embodiment is the component that can arbitrarily be called, for example, can be can be with picture pick-up device phase intercommunication
The component of letter, for obtaining the data message in picture pick-up device.
It is to be appreciated that the subprocess for starting failure, host process can be monitored and restart.Specifically, referring to figure
4, it can also include after the step S102 of above-mentioned embodiment illustrated in fig. 1:
Step S104:The host process monitors whether each subprocess starts success, when monitoring to start failure
During subprocess, the host process restarting subprocess for starting failure is until success.
Wherein, after host process starts subprocess, it can further monitor whether each subprocess starts success.If monitor
When starting the subprocess of failure, host process can restart the subprocess until starting successfully, so as to ensure each subprocess and group
Data communication between part.
It is to be appreciated that in the embodiment shown in fig. 4, step S104 is performed before step S103, that is to say, that, it is necessary to
Each subprocess is all started into success, recycles each subprocess to enter row data communication.Or step S104 can be with step
S103 is performed simultaneously, i.e., on the one hand host process restarts the subprocess of failure, can also on the one hand be utilized and started success
Subprocess realize between caller and corresponding component data communication.
Subprocess has certain cycle of activity, and it can be exited by main program.Alternatively, host process can be tied calling
Shu Hou, terminate subprocess.I.e.:
When receiving when exiting command of the caller transmission, the host process exits each subprocess.Tool
Body, at the end of invocation component, caller can send and exit command, and host process receives when exiting command, and terminates each
Subprocess.
In addition, host process can also monitor the activity time of subprocess, when some subprocess and inactive and reach certain
After time threshold, then it can be rejected.I.e.:
The host process record and each duration for starting successful subprocess and not entering row data communication;Work as institute
When stating the duration and reaching preset duration, the host process exits subprocess corresponding with the duration.
Certainly, host process terminates the mode of subprocess and is not limited thereto, and when can also be that host process exits, exits each
Subprocess.In addition, the main body for exiting subprocess can also be caller, i.e., when caller no longer needs to call subprocess
When, directly sent to subprocess and terminate order, for exiting subprocess.
Alternatively, on the basis of above-mentioned embodiment illustrated in fig. 1, can also include:
When subprocess is with respective corresponding module data communication failure, the process name of the subprocess is exported.
Specifically, when there is some subprocess with each self-corresponding module data communication failure, then communication mistake is exported
The process name of the subprocess lost.Wherein it is possible to be the subprocess of host process Monitoring Data communication failure, host process exports the son and entered
The process name of journey, or the subprocess itself of data communication failure export the process name of oneself.The process name of subprocess is exported,
The component for malloc failure malloc occur can be accurately positioned, compared with prior art, improves the positioning validity of problem component.
