Fail to init with delve

[nemotoo]

System

• macOS 10.12.3
• go 1.8 with brew
• delve 0.12.1
• both iterm2 and default terminal
• termbox-go (91bae1b)

With delve, termbox.Init() fail with "SYS_IOCTL: interrupted system call" err.
What should I do for debugging with delve?

Have no idea. I don't have and don't use macosx. To debug it obviously you need to understand how termbox works and what it does. Source code is there. It's not a big lib.

Also is delve a Go debugger? Don't use it as well. But maybe it it works under linux I'll take a look at the weekend.

A workaround is to run the termbox-go application, and then attach with delve from another terminal.

./tb-app
dlv attach <PID>

This allows delve to manipulate the terminal in its own terms, while termbox-go manipulates the other terminal in its own. It's a bit more tedious, especially since you need to find the PID of the app you're debugging, and you might want to block the app's execution until after you've attached, probably using a signal. But using the $! variable in bash you can easily get the PID of the last process and automate this using a small script (works especially well with a terminal multiplexer, since you can actually execute things in both terminals through the script to set everything up).

as soon as I attach with delve input no longer works in the application - the application continues to run though. makes it impossible to control the application in order to reach a desired breakpoint. any work arounds for this?
