when Skynet is started, a logger context is created based on the log file of the configuration file, the process is to find the logger.so dynamic link file, and then call its logger_create function (parameter is the log file of the configuration), It then constructs the context for the service (it is important that the service's callback function _logger ()) and Message Queuing are registered, and finally executes the logger_init function, putting log
There are many configurations on the web that introduce logger, but I found scrapy in the process of execution, and the location of logger.cfg files is also required because scrapy and the common Python script root directory are different The green font below indicates that the root of scrapy is the direct parent directory with Scrapy.cfg and the root of the red font is the direct ancestor directory with settings.py, Here is the difference, to want

Log functions in a multi-threaded environment should be able to synchronize, multiple threads at the same time log output to the same log file, every time the log records should be kept intact, that is, the log function to achieve synchronous processing. The following example uses Poco multithreaded programming to start 200 child threads at a time, and each child thread function is responsible for writing its own log contents to the log file.
