Thu Mar 28 09:21:16 1996 Michael I. Bushnell, p/BSG * mgt.c (S_proc_reassign): Make send once right directly from value in P->p_pi, don't use ports_get_right. * mgt.c (process_has_exited): Inhibit this call from happening twice. * info.c (S_proc_pid2task): Return MACH_PORT_NULL for a zombie.

[Incorrect semantics were in loop to search zombies, and loop looking for stopped children] (reparent_zombies): Likewise. [Incorrect semantics were in PID check before returning startup_proc's wait.] (alert_parent): Likewise. [Incorrect semantics were in PID check before returning P->p_parent's wait.] * wait.c (S_proc_wait): Only return wait on stopped child if it passes the PID test. * pgrp.c (S_proc_setpgrp): Don't do process group change if we are changing into our own process group. * mgt.c (S_proc_child): Likewise. * pgrp.c (S_proc_setpgrp): When PID is zero, act on calling process; when PGID is zero, use pid of affected process. (S_proc_setpgrp): EPERM check should succeed if pgid is the affected process's *pid*, not pgrp. Thu Jun 30 08:40:35 1994 Roland McGrath (roland@churchy.gnu.ai.mit.edu) * mgt.c (S_proc_dostop): Use the proper allocation for task_threads. Check for errors. Deallocate the send right from CONTTHREAD too. * wait.c (alert_parent): Send SIGCHLD to the parent. Tue Jun 28 18:12:43 1994 Roland McGrath (roland@churchy.gnu.ai.mit.edu) * primes.c: Include . (nextprime): Use calloc instead of alloca, bzero. P might be 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) * main.c (main): Set priority of proc server to 2 so that we get more CPU than ordinary programs. Fri Jun 24 17:29:55 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * hash.c (struct htable): New member `locps'. (addhash): Store LOCP into hash table for use during rehash. During rehash, then provide correct LOCP parm for old elements. Allocate and free HT->locps as appropriate. Fri Jun 24 04:15:16 1994 Roland McGrath (roland@churchy.gnu.ai.mit.edu) * mgt.c (S_proc_setprocargs): Renamed to S_proc_set_arg_locations. (S_proc_get_arg_locations): New function. Mon Jun 20 15:07:00 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * Makefile (install): Use $(INSTALL_BIN) instead of cp. Fri Jun 17 13:00:27 1994 Michael I Bushnell (mib@geech.gnu.ai.mit.edu) * mgt.c (S_proc_child): Reverse Roland's change of June 11. Sat Jun 11 11:20:16 1994 Roland McGrath (roland@geech.gnu.ai.mit.edu) * mgt.c (S_proc_child): Inherit the argv and envp values from the parent. Fri May 27 16:03:53 1994 Michael I Bushnell (mib@geech.gnu.ai.mit.edu) * primes.c: Doc fix, with appreciation to Jim Blandy. Fri May 13 16:58:13 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * 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. * msg.c (S_proc_setmsgport): Take new reply port args. Send reply before trying startup_essential_task. Include to declare startup_essential_task. * cpu-types.c: New file. * Makefile (SRCS, OBJS): Add it. * host.c: Include for sprintf. (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. (initialize_version_info): Allocate space for machversion. 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).
