* Move open_fhs from fhandler.h to cygheap.h for easier tracking. AccommodateChristopher Faylor2003-12-301-2/+3
| | | | | | | | | | | | | | | | | | | | | this change throughout. * dtable.cc (dtable::add_archetype): Use correct count when iterating through *active* archetypes. * dtable.cc (dtable::fixup_after_exec): Close handle if close_on_exec and archetype exists since archetype currently does not set windows close-on-exec flag (FIXME). * fhandler_tty.cc (fhandler_tty_slave::open): Change debugging output slightly. (fhandler_tty_slave::close): Ditto. (fhandler_tty_slave::fixup_after_fork): Just report on inherited use counts since since archetype currently does not set windows close-on-exec flag (FIXME). * pinfo.cc (_pinfo::set_ctty): Change debugging output slightly. * cygheap.cc (cygheap_init): Remove open_fhs accommodation and use count reporting. * perthread.h (vfork_save::fhctty): New element. * perthread.h (vfork_save::open_fhs): New element. * fork.cc (vfork): Muck around with ctty and open_fhs stuff, both of which are now saved in the vfork_save structure.
* * syscalls.cc (close_all_files): Simplify logic around closing ctty.Christopher Faylor2003-12-271-9/+6

* * fhandler.h (fhandler_tty_master::fixup_after_fork): Remove declaration.Christopher Faylor2003-12-271-2/+1

* * exceptions.cc (try_to_debug): Fix off-by-one problem when resettingChristopher Faylor2003-12-271-1/+1
