| | | | | | | | | | | | | | | | | | | | | 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.
* * fhandler.h (fhandler_tty_slave::archetype): Make public.Christopher Faylor2003-12-271-1/+7
| | | | | | | | | | | | | (report_tty_counts): New macro. Use throughout for reporting tty use counts. * dtable.cc (dtable::vfork_child_dup): Add debugging output for usecount increment. Increment open_fhs if appropriate. (dtable::vfork_parent_restore): "Close" artificially bumped ctty. (dtable::vfork_child_fixup): Close ctty since it was bumped prior to vfork. Save open_fhs around close since the closing of these handles has no effect on the console. * fhandler_tty.cc (fhandler_tty_slave::open): Reorganize calls to allow for easier tracking of usecount modification. (fhandler_tty_slave::open): Ditto.
