Removed files:
winsup/cygwin : perthread.h
Log message:
* child_info.h (child_info_spawn::hexec_proc): Eliminate.
* 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.
