Single-file Windows frpc service wrapper. Features: - Embeds frpc v0.70.1 (16.7MB) into one 18.9MB EXE - Registers as Windows Service (auto-start, no login required) - Auto-detects frpc config by three-tier search: 1. frpc.ini 2. frpc.toml 3. any *.ini/*.toml in exe dir - Self-healing supervisor: frpc crashes are restarted with exponential backoff (2s..60s), capped to avoid log spam - Console subsystem so install/start show feedback - FreeConsole on SCM start to suppress console window - Logs to <exe-dir>/logs/service.log Subcommands: install start stop remove import -d Smoke test (smoke_linux.go) covers all config detection paths including the custom-name (e.g. frpc-mike.ini) use case.

// Package logger 提供一个轻量日志器,把消息写入指定目录下的 service.log。
|
|
//
|
|
// 设计要点:
|
|
//
|
|
// - 文件日志始终启用,便于事后取证
|
|
// - 所有写入加锁,frpc 输出 + 本服务输出可能并发
|
|
// - 服务模式下,日志必须写到 EXE 同目录(SCM 默认工作目录是 System32)
|
|
// - 不再同时写 stdout - 服务模式已经 FreeConsole,CLI 模式 stdout 由 main 自己处理
