Operating system

Others

System version

NA

Installation type

Original sing-box Command Line

If you are using a graphical client, please provide the version of the client.

No response

Version

v1.8.12 / 1.9.0rc14

Description

If log writes to file and tcp/udp routed to different outbounds, this leads to crash, because logger.Log() called before logger.Start()

Reproduction

config.json

{
	"log": {
		"output": "sing-box.log"
	},
	"inbounds": [
		{
			"tag": "in",
			"type": "socks",
			"listen": "127.0.0.1",
			"listen_port": 2080
		}
	],
	"outbounds": [
		{
			"tag": "out",
			"type": "socks",
			"server": "127.0.0.1",
			"server_port": 2081
			// This guy
			,"network": "tcp"
		}
	]
}

Integrity requirements

• I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
• I confirm that I have provided the server and client configuration files and process that can be reproduced locally, instead of a complicated client configuration file that has been stripped of sensitive data.
• I confirm that I have provided the simplest configuration that can be used to reproduce the error I reported, instead of depending on remote servers, TUN, graphical interface clients, or other closed-source software.
• I confirm that I have provided the complete configuration files and logs, rather than just providing parts I think are useful out of confidence in my own intelligence.
