pkg/debugdetect: add package for detecting debugger attachment#4258
Merged
Conversation
Implement new pkg/debugdetect package that detects if a program is running under a debugger on Linux, macOS, Windows, and FreeBSD. Platform-specific detection methods: - Linux: Parse /proc/self/status for TracerPid field - macOS: Use sysctl with KERN_PROC_PID to check P_TRACED flag - Windows: Call IsDebuggerPresent() Win32 API - FreeBSD: Try sysctl first, fall back to /proc/curproc/status Related to go-delve#4243 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Maybe we should make this an helper function.

I thought about that but it seems easy enough for an end user to implement and there's too many potential variables for that the API should look like. Should it accept a context? Should it accept a timeout param? How opinionated should it be? Seems like users writing a solution on top of our building block thats suitable for their use case is better. Happy to discuss further though.

I'd say just the basic loop:
for {
attached, err := IsDebuggerAttached()
if attached || err != nil {
return err
}
time.Sleep(500 * time.Millisecond)
}
anything different written by the user using IsDebuggerAttached.
