So to clear things up:
-t or --tty will attempt to launch the process in a _separate_terminal_window_
(open a new terminal window and launch your process within it so the process
gets its own window and we don't have to shared IO) and should never be used
with -n (--no-stdio). If they currently can be run together then this is a bug.
--tty isn't supported on Linux as far as I know and the linux launch code
should return an error saying this isn't supported. The --tty option is
designed to be used when you want to debug anything that uses curses (emacs,
vi, etc) and where having a different terminal window with its own
stdin/out/err is required.
--no-stdio should, as you surmised, launch a process with /dev/null as the
stdin/out/err. It also means we should always have a prompt.
To to summarize:
(lldb) process launch ...
No LLDB prompt while running as all input goes to process (though if CTRL+C is
pressed and we will stop the target for you)
(lldb) process launch --tty -- ...
LLDB prompt always visible, process launches in a different terminal window,
not supported on linux, should never be used with --no-stdio and if our options
allow it, this is a bug
(lldb) process launch --no-stdio -- ...
LLDB prompt always visible (if not, then a bug, probably only on the linux
side).
Thanks for confirming this.
I might have a look at fixing the linux bug in a few weeks if the rest
of my work permits.
