bug: Multiprocess cannot write log to the same file

[nguyenhoangthuan99]

Problem
In windows, once a file is taken by one process, other process can not modify it. For example, when the server is writing to log file, it hold cortex.log, and if we run CLI command, it cannot write message to cortex.log.

Solution
In window, we are planning to use Unix Domain Socket to start a thread and write log to file. Below are detail implementation:

• When start server, will create a thread to run UDS to listen messages and write to logfile.
• From server side, override log method of Trantor to send log message to UDS server
• From CLI side, when execute command, check if UDS server is live, if not write directly log to log file.
• With command has --verbose flag, log everything to terminal.

For windows, we are planning to use Unix Domain Socket to communicate between process, only one process will write to log file

@nguyenhoangthuan99 Question from my side - did we consider having a separate log for CLI and Server?
