Sorry, I don't understand this. Surely if we attach the inferior's (i.e.
what you termed the process) standard IOs to a pty, then we *will* get a
prompt, since then lldb can use it's terminal with no corruption from
the inferiors in/out?
(I'm not actually clear about the relationship between the "process
launch" -t and -n commands. I do accept that they are mutually
exclusive. I assume, -n means that the stdin/out/err of the inferior is
closed, so that lldb has complete use of the foreground, so it could use
it's prompt. I assume -t means attach the inferior to a different pty,
so again, lldb should still be able to use it's prompt.)
It is probably a bug where if you launch with --no-stdio that the LLDB prompt
isn't always active.
For attach, we will always have a prompt.
So seems this is a bug that --no-stdio is still pushing a Process IOHandler and
taking over the console while the process is running.
So you are saying if I do
(lldb) process launch -s --no-stdio
then
(lldb) process continue
then I should always see:
(lldb)
back on my terminal?
Todd, could you try this (a couple of times, in case I'm seeing
something intermittent) please, to see if your observations agree?
thanks
