Abstract
The invention provides a dual-thread-based journal output method and device. The method includes: receiving a journal calling request, and storing journal text data in the journal calling request in a thread circulating queue; writing the journal text data stored in the thread circulating queue into a blocking queue which is an internal memory buffer area; monitoring the capacity and writing operation of the blocking queue, and if the fact that the blocking queue has no writing operation or reaches a capacity threshold, trigging the input-output thread of a journal to write all current journal text data in the blocking queue into a journal file in one time. By the journal output method and device, the writing frequency of internal memory buffer area data into the journal file is low, the number of threads used by journal process is reduced, system I/O pressure is low, journal redirection is achieved by a small amount of CPU and thread resources, and the response performance of UI Interaction in applications is increased.
Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of log-output method and device based on dual-thread.
Background technology
Developer understands application program (Application, abbreviation：APP operation conditions), the conventional side of one of which
Method is, by daily record, daily record to be redirected, and output to specified journal file carries out unifying to collect.
In the prior art, when daily record is exported, start a thread, journal file is opened in the thread, then
Daily record data is written in journal file, last closing journal file, terminates thread.Therefore, a daily record is often write, it is necessary to
Flow for journal file of experience " open file handle -- write-in data-closing file handle ".
But, when a large amount of continuous daily records are exported, by above-mentioned log-output method, it is easily caused reading and writing of files frequently
It is numerous, pressure is brought to system input and output (I/O), and the Thread Count that treatment daily record is used is excessive, can consume mobile device valuable
Thread resources, reduce CPU and distribute to the timeslice of Business Processing.
The content of the invention
The present invention provides a kind of log-output method and device based on dual-thread, easy to solve existing log-output method
Cause reading and writing of files frequently, the big problem of system I/O pressure.
In a first aspect, the present invention provides a kind of log-output method based on dual-thread, including：

In；
The daily record text data write-in obstruction queue that will be stored in the thread loops queue, the obstruction queue is internal memory
Buffering area；
Monitor it is described obstruction queue capacity and write operation, if listen to it is described obstruction queue do not have write operation or
Capacity threshold is reached, then triggers the input and output thread of daily record, by current all of daily record text data in obstruction queue
One-time write journal file.
Further, current all of daily record text data one-time write daily record text in the queue by the obstruction
Part, including：
Journal file handle is opened, current all of daily record text data is obtained successively from obstruction queue, successively
Each daily record text data is write in the journal file, current all of daily record text data writes the journal file knot
Shu Shi, closes the journal file handle.
Further, before the reception daily record call request, also include：
The priority of the thread priority less than Business Processing of the thread loops queue is set.
Further, it is described listen to it is described obstruction queue there is no write operation, including：

Body can be terminal device, such as mobile phone, IPAD electronic equipments, as shown in figure 1, the method for the present embodiment can include：
S101, reception daily record call request, by the daily record text data store in daily record call request in thread loops team
In row.
Wherein, the daily record that thread loops queue is used in the daily record call request received according to queue FIFO storage
Text data, when daily record is exported, will start a thread, and the daily record call request is exactly that the thread before daily record output is adjusted
With request.
S102, the daily record text data write-in obstruction queue that will be stored in thread loops queue, obstruction queue are slow for internal memory
Rush area.
Wherein, core buffer is, for example, high-speed internal memory buffering area.
S103, the capacity for monitoring obstruction queue and write operation, if listen to obstruction queue and there is no write operation or reaching
To capacity threshold, then the input and output thread of daily record is triggered, current all of daily record text data in obstruction queue is disposable
Write-in journal file.
Specifically, there is no write operation or reach capacity threshold if listening to obstruction queue, will be current in obstruction queue
All of daily record text data one-time write journal file, is specifically as follows：
Journal file handle is opened, current all of daily record text data is obtained successively from obstruction queue, write successively
The corresponding daily record data of each thread in journal file, at the end of current all of daily record text data write-in journal file,
Closing journal file handle.Capacity threshold therein is, for example, block capacity of queue 80% or 90% etc..
So as to current all of daily record text data disposably all writes journal file in obstruction queue, and daily record is literary
The opening and closing of part handle only need each execution once, therefore the frequency of daily record text data write-in journal file is low, to system
I/O pressure it is small.
Further, listening to obstruction queue does not have write operation, Ke Yiwei：Listen to obstruction queue in Preset Time
There is no write operation, Preset Time can be a default time period, such as 5S.
In the present embodiment, it can be seen that using the log-output method of the present embodiment, dual-thread asynchronous write data, one
Thread is responsible for for the daily record text data in daily record call request writing core buffer, and a thread is responsible for monitoring memory buffer
Area when trigger condition is met by the daily record text data one-time write journal file in core buffer, log buffer and
During write-in works sub-line journey at two respectively, the frequency of buffer data write-in journal file (i.e. disk file) is low, reduces
The Thread Count that treatment daily record is used, it is small to system I/O pressure, the redirection of daily record is realized with less CPU and thread resources, carry
The interior user interface of height application (User Interface, referred to as：UI) the response performance of interaction.
Further, before receiving daily record call request in S101, can also include：The line of thread loops queue is set
Priority of the journey priority less than Business Processing.So that terminal device receives daily record call request at the same time and Business Processing please
When asking, the time of Business Processing can not be influenceed with priority treatment business.
The log-output method based on dual-thread that the present embodiment is provided, after receiving daily record call request, uses one
Daily record text data in daily record call request is write core buffer by individual thread, and a thread is monitored core buffer and do not had
By in the daily record text data one-time write journal file in core buffer when having write operation or reaching capacity threshold,
During log buffer and write-in work sub-line journey at two respectively.So as to, the frequency of core buffer data write-in journal file is low,
The Thread Count that treatment daily record is used is reduced, it is small to system I/O pressure, realize and realize day with less CPU and thread resources
The redirection of will, improves the response performance of application interior UI interactions.
