Asynchronous Log Administration System provided by the invention can be realized by the step process of asynchronous blog management method.
Asynchronous blog management method can be interpreted as the preference of the asynchronous Log Administration System by those skilled in the art.
The present invention relates to there is a High-Performance Asynchronous log library, High-Performance Asynchronous log library is the list of the producer more than one
The model of consumer provides a set of lightweight, high performance C log library to developer, embeddable to arrive any client or clothes
It is engaged in device.It can be used in windows and Linux system.It is not only suitable for general PC operating system project, also can operate with
To in the exigent embedded system of Memory Allocation.For front end interface user, accomplish non-obstruction addition, then first day of the lunar year will
Write-in it is noted that disk I/O bottleneck.The present invention provides 0~4 totally 5 output journal grade interfaces, respectively BASEDEBUG,
Rating is arranged when initializing log in DEBUG, WARN, ERROR and FAULT.Log calls write frequently to will lead to
Expense of uniting is very big, therefore designs a buffer and store log content, the one-time write after buffer is full.This hair
Bright is to apply for muti-piece buffer when initializing with local multiple buffer technology, using main thread call log interface to
Data in buffer are extracted write-in file by number completion evidence in buffer, backstage log.Content is embodied: first to file is worked as
Preceding buffer area buffer and two pieces of idle buffer, respectively buffer1, buffer2.When current buffer is fully written, first
Current buffer is moved into buffer1, then buffer2 is converted into current buffer, then buffer1 write-in log text
Part.The effect of this realization withouts waiting for disk I/O operation when being mainly reflected in newly-built log information, reduce and wait.It writes
It may be blocked in current location when entering log, to guarantee that main thread is not blocked, need individually to apply for thread process log
IO write-in.The model of more producer's list consumers is being that log itself is used as a background thread to go to complete by the example in invention
Journalizing, here as the consumer of log.And the main thread being applied to is to be responsible for passing through printing for the producer of log
Interface removes production daily record data.Such model mechanism cooperate more buffer bufferings can make to call using main thread log interface at
For non-blocking operation.
Log library also stores log head information, such as time, affiliated not only by the write-in disk of content intact
Module, specific thread information, file line number etc..Therefore each grade interfaces need to realize its head and body.To guarantee log library
Thread-safe needs to be added log lock.When journal file is more than the maximum length of setting, file is replicated and creates new file.
In specific implementation, PC client software needs developer to carry out white-box testing to different block codes.
Firstly, data are sent server by HTTP by developer, http response time-out or normal response are wondered.Then, in mould
This log library is initialized in block, calls respective level interface.After executing code white-box testing, catalogue where log, exhibition are opened
Log file is opened, program flow logic can be analyzed.
One skilled in the art will appreciate that in addition to realizing system provided by the invention in a manner of pure computer readable program code
It, completely can be by the way that method and step be carried out programming in logic come so that provided by the invention other than system, device and its modules
System, device and its modules are declined with logic gate, switch, specific integrated circuit, programmable logic controller (PLC) and insertion
The form of controller etc. realizes identical program.So system provided by the invention, device and its modules may be considered that
It is a kind of hardware component, and the knot that the module for realizing various programs for including in it can also be considered as in hardware component
Structure；It can also will be considered as realizing the module of various functions either the software program of implementation method can be Hardware Subdivision again
Structure in part.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make a variety of changes or modify within the scope of the claims, this not shadow
Ring substantive content of the invention.In the absence of conflict, the feature in embodiments herein and embodiment can any phase
Mutually combination.
