TD-SCDMA in China has made a breakthrough in system, chip and terminal. TD-SCDMA System equipment basic functions have been achieved, stable performance. Many handset manufacturers can provide mobile phones in small quantities at the end of the year. TD-SCDMA Commercial preparation work has been basically completed, initially with an annual output of the base station system million-channel industrial scale. (Computer science)

The log system in the python standard library is supported from Python2.3. You only need to import the logging module. If you want to develop a log system, you need to output logs to the console and write log files as long as they are used as follows:

Log information is a very useful method for debugging during software development, especially when many related personnel need to collaborate in large-scale software development. By adding some specific event information in the code that can record the software running process, developers can identify problems in the code. This information may include the time, description, and specific context
I have already explained how to use log4cxx for logging. Today the problem is a little complicated. The reason is that a DLL used in the system has used log4cxx. We also want to use log4cxx during the development process, but we don't want to write the logs in the DLL to the same file. The problem arises. How can we print the logs to different files, the DLL adopts the getrootlogger method.

Boost library to access thread-local storage, each thread needs to initialize the smart pointer when it first attempts to get an instance of it, and the thread-locally stored data is freed by the Boost library when it exits.
The advantages of multithreaded logging using thread-local variables:
It is easy to implement a thread-level single log system using static thread-local variables.
It is simple and convenient to access the generation and cleanup of thread local storage through the intell

Logging Module Introduction
Python's logging module provides a common logging system that can be easily used by third-party modules or applications. This module provides different log levels and can record logs in different ways, such as files, HTTP get/post,smtp,socket, etc., and can even implement specific logging methods on their own.The logging module is the same as the log4j mechanism, but the specific implementation details are different. module provides
1, what is log4j?
Log4j is an open source project for Apache, by using log4j, we can control the destination of log information delivery is console, file, GUI component, even interface server, NT Event recorder, UNIX syslog daemon, etc. We can also control the output format of each log, and by defining the level of each log information, we can control the log generation process more carefully. Most interesting of all, these can be configured flexibly with a single configuration file without the
Log4j is an open source project for Apache. By using log4j, programmers can control the destination of log information delivery, including consoles, files, GUI components, and NT event loggers, and can control the output format of each log, or control the log generation process more carefully by defining the level of each log message. The following code is an example://log4j PublicvoidLog4jdemo (){Logger Logger
into log4j (createdate, thread, priority, category, message) values ('% d {iso8601}', '% t',' %-5 ', '% C',' % m') and the configuration file will be referenced in the program. The definition is as follows: Import org. Apache. log4j. Logger;

I. Introduction to log4j Components
A: Three important components of log4j: loggers, appenders, and layouts
These three components work together to enable developers to record information based on information categories and levels, andDuring operation, the log storage location has been controlled by the information record method.
B: logger hierarchy)
Almost all APIs that record logs have functions that go beyond the simple system. Out. Print statemen

Log4j This dongdong, everyone has been using, but really how many people know, why to be like that with the column. Or how many do not copy can own a log4j column. Readers can ask themselves if they can do it. In this chapter, we will analyze some important links combined with source code.
First, log4j is the place to read the configuration file.
Before answering this question, first think about how we use log4j to print the log in the program.
