* dcrt0.cc (dll_crt0_0): Remove hexec_proc stuff. * fork.cc (fork_child): Remove call to pinfo_fixup_after_fork. * pinfo.cc (set_myself): Close and zero pid_handle if set. (pinfo_fixup_after_fork): Delete. (proc_waiter): Don't close vchild.hProcess here. Do that when we are remove the vchild from procs. Save hProcess as pid_handle only on first reparent operation. (pinfo::wait): Don't set pid_handle here. (pinfo::alert_parent): Always try to send signal. If unsuccessful then close and zero wr_proc_pipe. * pinfo.h (pinfo::pinfo): Make sure that appropriate parts of the class are zeroed on construction. (pinfo::alert_parent): Take char argument. (pinfo_fixup_after_fork): Delete declaration. (hexec_proc): Ditto. * sigproc.cc (remove_proc): Close pid_handle and hProcess if appropriate. * spawn.cc (spawn_guts): Set cygheap->pid_handle on first exec. * cygheap.h (init_cygheap::pid_handle): New element. * pinfo.cc (set_myself): Clear previously existing cygheap->pid_handle when a new process has been started. (pinfo::wait): Make sure that a handle to the newly forked/spawned process is kept around so that the pid will not be reused. * pinfo.h (_pinfo::pid_handle): Move. (pinfo::pid_handle): to here. * spawn.cc (spawn_guts): Create a pid_handle in cygheap prior to spawning to ensure that the pid does not get reused during the lifetime of the "cygwin pid". * pinfo.h (pinfo::alert_parent): New function. * exceptions.cc (sig_handle_tty_stop): Use alert_parent to send "signals" to parent. * fork.cc (fork_parent): Don't close pi.hProcess. Let the waiter thread do that. * pinfo.cc (proc_waiter): Detect case where process exits without setting the exit code and use value from GetExitCodeProcess. Reluctantly implement __SIGREPARENT. (pinfo::alert_parent): Define. * sigproc.h (__SIGREPARENT): New enum. * spawn.cc (spawn_guts): Send reparent signal to parent on exec. Always create process in suspended state to avoid races. Remove cygthread.h in favor of cygtls.h throughout since cygtls now includes cygthread.h. Eliminate ppid_handle usage throughout. * child_info.h: Regenerate magic number (child_info): Remove pppid_handle. * cygthread.h (cygthread::release): New method. Frees thread without waiting. * cygthread.cc (cygthread::stub): Set _ctinfo in _mytls to point to information for executing thread. Don't call SetEvent if thread is no longer in use. (cygthread::simplestub): Ditto. * cygtls.h (_cygtls::_ctinfo): New element contains pointer to information about executing cygthread, if any. * dcrt0.cc: Remove last vestiges of per_thread stuff. (dll_crt0_0): Ditto. Remove accommodation for ppid_handle. (do_exit): Remove obsolete reparenting test. (_exit): Exit with a more SUSv3-like exit value. * dtable.cc (dtable::stdio_init): Check for myself->cygstarted rather than myself->ppid_handle to see if we were started by a cygwin process. * exceptions.cc (open_stackdumpfile): Ditto. (handle_exceptions): Ditto. (ctrl_c_handler): Ditto. (sig_handle_tty_stop): Ditto. Let parent send signal to itself on STOP. (sigpacket::process): Comment out vfork test. (signal_exit): Use more SUSv3-like exit value on signal. * external.cc (fillout_pinfo): Don't set hProcess. * fork.cc: Remove VFORK cruft. (per_thread::set): Delete. (fork_child): Remove perthread stuff. (fork_parent): Remove obsolete subproc_init. Accommodate new method for tracking subprocesses. * pinfo.cc (set_myself): Accommodate new pinfo/_pinfo layout. Set some things here that used to be set in wait_sig. (_pinfo::exit): Set exitcode here. Close process pipe. (_pinfo::commune_send): Accommodeate new pinfo/_pinfo layout. (proc_waiter): New function. Waits, in a thread for subprocess to go away. (pinfo::wait): New function. Initialization for proc_waiter. * pinfo.h (_pinfo::exitcode): New element. (_pinfo::cygstarted): Ditto. (_pinfo::wr_proc_pipe): Ditto. (_pinfo::ppid_handle): Delete. (_pinfo::hProcess): Delete. (_pinfo::lock): Delete. (pinfo::hProcess): New element. (pinfo::lock): Ditto. (pinfo::wait): Declare new function. (pinfo::preserve): Define new function. * sigproc.cc: Remove old stuff from wait_subproc thread based method. (zombies): Remove. (procs): New. (my_parent_is_alive): Just check that the parent pid exists. (mychild): Just use pinfo methods to determine if child is mine. (proc_subproc): Revamp PROC_ADDCHILD to use pinfo::wait. Remove PROC_CHILDTERMINATED logic. Use different method to remove processes from list when SIGCHLD == SIG_IGN. (proc_terminate): Gut. (subproc_init): Delete. (init_child_info): Remove setting of pppid_handle. (checkstate): Revamp to only scan procs array. (remove_proc): Rename from remove_zombie. Don't close hProcess or pid_handle. Don't release memory if it's myself. (stopped_or_terminated): Change logic to handle new consolidated proc/zombie array. (wait_subproc): Delete. * sigproc.h: Remove obsolete EXIT_* defines. (subproc_init): Remove declaration. * spawn.cc (spawn_guts): Remove reparenting stuff. Use standard wait logic to wait for child if started from a non-cygwin process. * tlsoffsets.h: Regenerate. * tty.cc (tty_init): Check for myself->cygstarted rather than myself->ppid_handle to see if we were started by a cygwin process. * include/sys/signal.h (external_pinfo::exitcode): Replace hProcess. * include/sys/wait.h (WCOREDUMP): Define. * fhandler_tty.cc (fhandler_tty_slave::read): Add debugging output for timeout case. * signal.cc (abort): Flag that we are exiting with the ABORT signal.
