With this change, we sometimes see "^D^H^H" at the head of the output of grep on Darwin/Mac OS X with whichever window systems (^H is actually in one character). It looks as if the tty echo option is not disabled and ^D is echoed back in response to process-send-eof. I think this is because Emacs may send some data before a subprocess completes tty options setup. On Darwin, vfork is defined as fork for the reason mentioned in src/s/darwin.h. /* The following solves the problem that Emacs hangs when evaluating (make-comint "test0" "/nodir/nofile" nil "") when /nodir/nofile does not exist. */ #undef HAVE_WORKING_VFORK #define vfork fork #define DONT_REOPEN_PTY (It actually hangs on Mac OS X 10.1.5 and 10.2.8 if process-connection-type is set to t. On Mac OS X 10.3.9 it seems not to hang. Are there any other problems with vfork on Mac OS X 10.3, which is based on Darwin 7?) Unlike vfork, the parent process may run before the child process executes the code between (v)fork and execve/_exit if fork is used. The current Emacs disables the tty echo option in the child process (for USG systems?) by calling child_setup_tty. The following patch does tty options setup before forking, and it works for me.
