2000-03-12  Roland McGrath  <roland@baalperazim.frob.com>

	(S_proc_getmsgport): Only check if the message port is still alive

	mach_port_get_refs to check if the port is dead.

	* mgt.c (S_proc_reassign): Use mach_port_destroy to release the
	old task port.

Tue Mar  9 13:11:43 1999  Thomas Bushnell, BSG  <tb@mit.edu>

	P->p_msgport anymore.
	* msg.c (message_port_dead): Delete function.
	(S_proc_setmsgport): Don't request a dead-name notification
	anymore.

	* proc.h (message_port_dead): Delete prototype.

	* mgt.c (S_proc_reassign): It's not necessary to re-request the
	task-death notification; we've moved both the task right and the
	proc port that gets the notification, so delete that.

	* mgt.c (S_proc_reassign): Use mach_port_destroy instead of
	mach_port_deallocate to release P->p_msgport, for the same reasons
	as the changes below.

Sun Mar  7 18:19:07 1999  Thomas Bushnell, BSG  <tb@mit.edu>

	* mgt.c (process_has_exited): Use mach_port_destroy instead of
 	mach_port_deallocate to release P->p_msgport.
	(complete_exit): Likewise for P->p_task.
	These changes eliminate a race; we are destroying the receiver of
 	the dead-name notifications on these ports, but if that means we
 	lose a notification, then the ref-count on the name will get
 	incremented and we can't re-decrement it since we never hear the
 	notification.

1999-03-06  Mark Kettenis  <kettenis@gnu.org>

	* notify.c (do_mach_notify_dead_name): Deallocate reference to
	DEADPORT.

	* host.c (initialize_version_info): Construct UNAME_INFO.machine
	with a dash instead of a slash so that it can be used as a file
	name component.

	* host.c (initialize_version_info): Copy our version into element
	0 of server_versions, not element 1.  Use HURD_VERSION instead of
	OUR_VERSION.  Use literal "proc" instead of OUR_SERVER_NAME.
	* proc.h (OUR_SERVER_NAME, OUR_VERSION): Delete macro.

Thu Sep 12 16:33:49 1996  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	pid_find_allow_zombie, not ordinary pid_find.

	* mgt.c (S_proc_reassign): Use new ports_transfer_right call
 	instead of claim/install sequence; the latter has leaves the port
 	out of any hash table for a time, which produces a race with
 	incoming messages.

	* proc.h (process_drop): New (inline) function.
	* hash.c (reqport_find): Only deallocate newly found reference
	if process is dead.
	* Makefile (MIGSTUBS): Delete process_replyUser.c.
	(MIGSFLAGS): Provide new definition.
	* msg.c (S_proc_setmsgport): Spawn thread to tickle init instead
	of sending reply here.
	(tickle_init): New function.

Mon Mar 25 17:02:04 1996  Michael I. Bushnell, p/BSG  <mib@gnu.ai.mit.edu>

	* Makefile (proc): Add libshouldbeinlibc.a.
	* main.c: Include <wire.h>.

	bigger than will fit on the stack.  Assert non-null return
	from calloc and realloc.

Tue Jun 28 13:57:08 1994  Michael I Bushnell  (mib@churchy.gnu.ai.mit.edu)

	* hash.c (struct htable): New member `locps'.

	* info.c (S_proc_getprocinfo): Only scan through the threads
	if task_info succeeds.

	* info.c (S_proc_getprocinfo): Behave properly if one of the
	threads has died in between the call to task_threads and the
	calls to thread_info (just pretend it never existed).

	* info.c (get_string, get_vector, S_proc_getprocinfo): If the task
	has died (there's a race between pending requests and processing
	of dead-name notifications) then convert MACH_SEND_INVALID_DEST to
	ESRCH.

Thu May 12 00:59:03 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* main.c (main): Take three args.  Store ARGV and ENVP in SELF_PROC.

	* info.c (S_proc_getprocargs): Remove `#ifdef notyet's.
	(get_string, get_vector, get_string_array): Functions exposed.
	(get_string_array): Set BP before the loop.  Use a for loop that
	iterates over elts in VECTOR.  Fix check of LEN to reallocate buffer.
	(S_proc_getprocargs): Cast BUF to vm_address_t * for get_string_array.
	(get_vector): Fix pointer arithmetic; break out of loop when done.
	Check for error from malloc.
	(get_string): Use memchr for scanning.  Check for error from
	malloc.  Pass READLEN correctly to vm_deallocate.

	(rebuild_uname): Removed unused variable J.
	(S_proc_register_version): Fix arg types.
	Use master_host_port, not host_priv.
	Remove unused variable J.
	(server_versions): Fix syntax errors in struct definition.
	(S_proc_uname): Fixed type of first arg.
	(rebuild_uname): Fix typo.
	(initialize_version_info): Cast args to host_info.

Mon May  9 14:32:37 1994  Michael I Bushnell  (mib@geech.gnu.ai.mit.edu)

	* mgt.c (new_proc): Regard init as having a dead message
	port initially.

	* msg.c (S_proc_setmsgport): When init chimes in, tell it
	we are essential.

	* proc.h (OUR_VERSION, OUR_SERVER_NAME): New macros.
	* host.c (uname_info, machversion, server_versions,
	nserver_versions, server_version_nalloc): New variables.
	(S_proc_register_version, rebuild_uname, initialize_version_info,
	S_proc_uname): New functions.
	(S_proc_sethostname): Also set uname_info.nodename.
	* main.c (main): Call initialize_version_info.

Fri May  6 13:00:36 1994  Michael I Bushnell  (mib@geech.gnu.ai.mit.edu)

	* host.c (S_proc_gethostname): If HOSTNAME is null, return
	an empty hostname instead of crashing.
	(S_proc_gethostname): Test buffer length properly; allocate
	space for the null too.

	* mgt.c (process_has_exited): delete unused variable LAST.
	* msg.c (check_message_return): delete unused variables I,
	MSGPORTS, and CP.  Changed type of second arg to `void *'
	so that the function type is appropriate for the first arg
	to prociterate.
	(check_message_dying): delete unused variable I.

	* wait.c, host.c, info.c, mgt.c, notify.c, pgrp.c: Changed MiG
	server stubs' return types from error_t to kern_return_t; the
	types are incompatible right now.

Thu May  5 07:50:24 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

	* Makefile: Change uses of $(headers) to $(includedir).
