Description
Technical field
The present invention relates to a kind of Internet communication technology field, in particular to it is a kind of based on more subprocess of single guiding systems with
And the technological frame of the fault-tolerant high stable of height of process signals processing.
Background technique
In March, 2007, National Administration for the Protection of State Secrets and The State Council IT Application Office, which combine, has issued " E-Government secrecy
Administration guide ".Regulation in " guide ": according to the technical requirements of information privacy, concerning security matters network cannot be directly connected to internet；It relates to
When close network and non-concerning security matters are connected to the network, if not concerning security matters network and internet are physically isolated, then concerning security matters are isolated using two-way gateway
Network and non-concerning security matters are connected to the network；If not concerning security matters network and internet are logic isolations, then pacified using security isolation and information
Full isolation realizes that concerning security matters network and non-concerning security matters are connected to the network with information one-way import system, guarantees confidential data not from High Security Level net
Network flows to Low Security Level network.
In general, the confidential data information of single guiding systems transmission includes file, database data, e-mail data
Deng.This just determines that single guiding systems are a kind of systems with certain complexity for handling Multi-task Concurrency, so using linear
The ordinary skill frame processing multitask of the one process of processing shows slightly inefficient.Existing common technology majority is based on the more of lightweight
Thread realizes, but due to more than the data task of single guiding systems and duty cycle circulation and to execute the time long, once there is one
Mission thread occur it is abnormal, then the whole system based on thread also can related appearance it is abnormal, so the scheme of multithreading and uncomfortable
Close single guiding systems.
Summary of the invention
To overcome above-mentioned the deficiencies in the prior art, this programme comprehensively considers the superiority and inferiority of various implementations, using multiple sons
Process corresponds to multitask, and zygote process exception signal processing takes over the mode reformed to abnormal task, realizes single guiding systems
The high efficiency of Multi-task Concurrency and high fault-tolerant high stability.
The present invention is handled using the processing multitask of more subprocess and subprocess abnormal signal capture, is saved in conjunction with persistence
The method of subprocess number and mission bit stream etc. realizes high efficiency, the high fault-tolerant and high stability of the Multi-task Concurrency of single guiding systems.
Due to single guiding systems data task more than and also task have loop cycle and task execution time long, so using subprocess independence
Execution task is optimal selection；And due to the independence of process, in some task process long-time implementation procedure if
Other task process will not be influenced by exception occur, as long as parent process handles sub- process exception signal capture, so that it may accomplish
Abnormal task is reformed by the adapter tube of seamless and efficient, realizes high fault-tolerant and high stability.
This programme implementing procedure is as follows:
1, then Anonymous Pipes of single guiding systems process application initialization for communication obtain institute's doing for task in need and believe
Breath.
2, a subprocess processing is distributed to each task.
2, in terms of subprocess, it is connected to the mission bit stream of parent process distribution, dynamic base needed for loading tasks does task.
3, in terms of parent process, bundle process number and mission bit stream persistence are saved, and to sub- process exception signal registration office
Reason.
If 4, subprocess occurs abnormal, and parent process catchs the exception signal immediately, and reads the subprocess of persistence preservation
Number and corresponding mission bit stream, obtain mission bit stream after, then the exception information is deleted inside the information of preservation, is jumped to
Step 2.
5, when subprocess finishes task, report mission bit stream to parent process by pipeline.
6, parent process while circulation reads duct size information and is handled if receiving the information that subprocess reports.
Technical solution of the present invention bring the utility model has the advantages that
Using the mode of the processing multitask of more subprocess and the processing of subprocess abnormal signal in the present invention, can make singly to lead
System concurrency handles multitask, and due to the independence of process, once, which there is exception, in some task process to be influenced
The operation of whole system can also capture the abnormal signal of task subprocess by parent process, and it is different to do to redistribute subprocess
Permanent business adapter tube and equal processing is reformed, single guiding systems is made to have the characteristics that high efficiency, the fault-tolerant, high stability of height.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is implementation flow chart proposed by the present invention；
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The invention implementing procedure is as follows:
1, then Anonymous Pipes of single guiding systems process application initialization for communication obtain institute's doing for task in need and believe
Breath；
2, a subprocess processing is distributed to each task；
2, in terms of subprocess, it is connected to the mission bit stream of parent process distribution, dynamic base needed for loading tasks does task；
3, in terms of parent process, bundle process number and mission bit stream persistence are saved, and to sub- process exception signal registration office
Reason；
If 4, subprocess occurs abnormal, and parent process catchs the exception signal immediately, and reads the subprocess of persistence preservation
Number and corresponding mission bit stream, obtain mission bit stream after, then the exception information is deleted inside the information of preservation, is jumped to
Step 2；
5, when subprocess finishes task, report mission bit stream to parent process by pipeline；
6, parent process while circulation reads duct size information and is handled if receiving the information that subprocess reports.
Code for example:
1. single guiding systems form task queue g_ after obtaining all mission bit streams, mission bit stream
OuterTaskInfoList, the types of variables are std::list<OuterTaskInfo>, and wherein OuterTaskInfo is to appoint
Business information structure, can be customized.Then a subprocess processing is distributed to each task, parent process is subprocess signal note
Volume event handling function, the code of part are as follows:
2. technical solution of the present invention is mainly in subprocess abnormality processing, wherein handling function sig_chld_handler's
Partial code is as follows:
3. being recognized that more subprocess of the present invention program handle Multi-task Concurrency from code flow above, combine
