Hello,
What were the changes done on Emacs 24.4 regarding subshells (or
processes), compared to version 24.2?
When compiled in the same environment, "tty" in a subshell
(M-x shell) has different outputs:
- in Emacs 24.2, "tty" outputs the tty,
- in Emacs 24.4, "tty" outputs "not a tty".
That is, if I run the command below to spawn a shell:
(apply 'start-process "shell" "*shell*" "/bin/ksh" '("-i"))
- in Emacs 24.2, "ps" shows the shell has a normal tty,
- in Emacs 24.4, "ps" shows the shell has a tty with "?".
I couldn't compile 24.3 due to some errors, so I don't know its behavior.
Thanks!
Georges
