From 578e142a2be9dcca7f64c54e6ae8cecd01e6ac71 Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Sat, 3 Jun 2006 06:35:10 +0000 Subject: [PATCH] * cygheap.cc (init_cygheap::close_ctty): Remove obsolete code. * dcrt0.cc (child_info_spawn::handle_spawn): Signal ready after we've run fixup_after_exec. * dtable.cc (dtable::fixup_after_exec): Add debugging output. * fhandler_tty.cc (fhandler_pty_master::doecho): Use class version of to_master. (fhandler_tty_common::close): Remove obsolete code. (fhandler_tty_slave::fixup_after_exec): Don't close, since this is done in dtable's fixup_after_exec. (revisit later?)
