I've just made some changes to the way Cygwin handles CYGWIN=tty. They speed output up ENORMOUSLY but I may have introduced synchronization issues between the tty child and the tty master. This also affects ptys. These changes will obviously be in the next snapshot but I would appreciate it if anyone who has the time could build this and check it out. I'll probably announce this on the cygwin mailing list but I'd like to have a slightly more limited audience try it out first. cgf Thu Sep 7 12:14:43 2000 Christopher Faylor <cgf AT cygnus DOT com> Split out tty and shared_info stuff into their own headers and use throughout. Include sys/termios.h for files which need it. * tty.h: New file. * shared_info.h: New file. * fhandler.h: Move inline methods that rely on tty stuff to fhandler_console.cc. * fhandler_tty.cc (fhandler_pty_master::process_slave_output): Set output_done_event immediately after reading data to speed up tty output processing. (process_output): Set write_error to errno or zero. (fhandler_tty_slave::write): Check previous write error prior to writing to slave end of pipe. This allows tty output to be slightly less synchronous. * fhandler_console.cc (fhandler_console::tcsetpgrp): Moved here from fhandler.h. (fhandler_console::set_input_state): Ditto.
