Code? On Jun 17, 2024, at 9:46 PM, Salvatore Domenick Desiano <neard...@gmail.com> wrote:
I've got some code that is basically Expect-lite written in Go. I've got a deadlock and I'm hoping someone here can help me untangle it. I posted this yesterday but at the time I thought the Expect part of the code wasn't relevant and I left it out. I now believe that part of the code is the problem.
I have: - exec.Command() with stdin and stdout replaced with io.Pipe()
- a Go routine listening to stdout, watching for strings, and writing to stdin
I know that Wait() won't return until stdin is closed. The problem is that I can't tell when I need to close stdin. Since Wait() doesn't return, the main thread can't do it. For some reason stdout doesn't get closed even with the program exits (stdout.Read() is part of the deadlock) so the Expect Go routine can't do it.
The only thing I can think of is another Go routine monitoring cmd.ProcessState but that doesn't feel right.
What am I missing?
Thank you!
