Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
[Message part 1 (text/plain, inline)]
after doing:
emacs -Q -f server-start&
emacsclient -t &
from a terminal, the terminal gets corrupted. The terminal shows the
emacs buffer, but the shell and not emacs receives the keystrokes.
Expected behaviour would be to stop emacsclient immediately when it is
started in the backround and needs the current tty. This would be
consistent with behaviour of "emacs -Q -nw &"
The attached patch for emacsclient.c fixes this problem by checking if
emacsclient is started in the background, and raising SIGSTOP, if that
is the case. This fixes the problem for me, but I cannot guarantee that
this has no side effects.

Thanks for the bug report. How about the attached (untested) patch
instead? It checks for tcgetpgrp failure. Also, the glibc manual
suggests that emacsclient should be killing its process group with
SIGTTIN, not itself with SIGSTOP. See:

yes, I can confirm that with your patch "emacsclient -t &" now works as
expected. Thank you!
