Ned Deily added the comment: I have not been able to reproduce the behavior you report using various Pythons on OS X 10.8 or on OS X 10.5. Can you give more specifics on the environment that fails for you?
I certainly don't claim to have any experience with these tty/pty modules or with the underlying system calls and I'm not sure what you are trying to do here but isn't it a bit risky to be calling tty.tcsetattr() from both the parent and child processes simultaneously, since the call is after the fork? tcsetattr is dealing with a job-wide data structure and, under the covers, the tcsetattr() function currently reads and writes various field non-atomically. What happens if you move the tcgetattr and tcsetattr to before the os.fork call or into the parent-only code after the "else"? http://hg.python.org/cpython/file/default/Modules/termios.c ---------- nosy: +ned.deily _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15898> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
