From 8f0c527e13b836a44fedbf6abc84e1901e2cc10d Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sat, 4 May 1996 09:46:57 +0000 Subject: Sat May 4 05:44:25 1996 Roland McGrath * hurd/hurd-raise.c (_hurd_raise_signal): Pass sigcode in msg_sig_post rpc. * hurd/hurdmsg.c (_S_msg_set_environment): Use argz.h functions instead of _hurd_split_args. (_S_msg_*_exec_flags): Functions removed. (_S_msg_startup_dosync): Stub removed. Sat May 4 02:11:55 1996 Roland McGrath * sysdeps/mach/hurd/ptrace.c: Set _hurdsig_traced instead of EXEC_TRACED bit in _hurd_exec_flags. Pass sigcode arg in msg_sig_post_untraced rpc. * sysdeps/mach/hurd/access.c: Don't pass io port in auth_user_authenticate rpc. * posix/sched.h: Fix typos. * sysdeps/mach/hurd/fork.c: Use new critical section lock. Clear _hurdsig_traced instead of EXEC_TRACED. * sysdeps/stub/nanosleep.c (nanosleep): Fix typo. * wcsmbs/wcstol.c: Find strtol.c in ../stdlib. * wcsmbs/wcstof.c: Find strtod.c in ../stdlib. * wcsmbs/wcstod.c: Likewise. * wcsmbs/wcstold.c: Likewise. * wcsmbs/wcwidth.h: Find cname-lookup.h in ../wctype. * string/envz.c (envz_entry): Use const. (envz_get, envz_remove): Likewise. (envz_entry): Return char *, not const char *. * string/envz.h: Fix decl. * string/argz-create.c: Use const in prototype. * string/argz-next.c: Likewise. * sysdeps/mach/hurd/sigprocmask.c: Pass sigcode arg to msg_sig_post. * sysdeps/mach/hurd/i386/sigreturn.c: Likewise. * sysdeps/mach/hurd/sigsuspend.c: Likewise. * sysdeps/mach/hurd/kill.c: Likewise. * hurd/hurdexec.c (_hurd_exec): Use new critical section lock. * hurd/catch-exc.c (_S_catch_exception_raise): Likewise. * hurd/sigunwind.c (_hurdsig_longjmp_from_handler): Likewise. * hurd/thread-cancel.c (hurd_thread_cancel, hurd_check_cancel): Likewise. * sysdeps/mach/hurd/jmp-unwind.c (_longjmp_unwind): Likewise. * sysdeps/mach/hurd/sigaction.c: Likewise. * sysdeps/mach/hurd/errnos.awk: Don't use ARGV in comment; it can change meaninglessly. * hurd/hurd/signal.h (struct hurd_sigstate): Replace critical section flag with a spin lock. (_hurd_critical_section_lock): Use spin_try_lock on that to see if we get it. No need to take SS->lock at all. (_hurd_critical_section_unlock): Unlock SS->critical_section_lock instead of clearing the old flag member. * hurd/hurdsig.c (_hurd_internal_post_signal): Use spin_lock_locked to test the critical section state. * hurd/hurdinit.c (_hurd_init): Set _hurdsig_traced from the intarray. * hurd/hurdkill.c (_hurd_sig_post): Pass 0 sigcode in msg_sig_post. * hurd/hurdsig.c (_hurd_internal_post_signal): Test _hurdsig_traced instead of testing (_hurd_exec_flags & EXEC_TRACED). (_S_msg_sig_post): Take sigcode arg and pass it through. (_S_msg_sig_post_untraced): Likewise. (reauth_proc): Don't pass proc port in auth_user_authenticate. * hurd/setauth.c (_hurd_setauth): Don't pass object ports in auth_user_authenticate RPCs, just the one-off rendezvous port. * hurd/dtable.c (reauth_dtable): Likewise. * hurd/hurdlookup.c (__hurd_file_name_lookup_retry): Likewise. * hurd/hurdexec.c (_hurd_exec): Pass 0 flags to file_exec. Pass sigcode arg to msg_sig_post. * string/argz.h (argz_create): Use const in prototype. * hurd/hurdinit.c (_hurd_proc_init): Test _hurdsig_traced instead of testing (_hurd_exec_flags & EXEC_TRACED). Pass sigcode arg to msg_sig_post. * hurd/hurd.h: Declare _hurdsig_traced. * string/argz.h (__argz_next): Cast ENTRY before returning it. * hurd/hurd/signal.h (_hurd_critical_section_unlock): Pass sigcode arg to msg_sig_post. * hurd/path-lookup.c: New file. * hurd/Makefile (routines): Add path-lookup. * hurd/hurd/lookup.h: Declare file_name_path_scan, hurd_file_name_path_lookup. * hurd/hurd.h: Declare file_name_path_lookup. * sysdeps/mach/hurd/select.c: The io_select rpc no longer has a TAG_ID argument. Instead, use a separate reply port for each RPC and put them all in a port set to wait for slow replies. --- string/envz.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) (limited to 'string/envz.c') diff --git a/string/envz.c b/string/envz.c index e751ecc..447b9e0 100644 --- a/string/envz.c +++ b/string/envz.c @@ -29,13 +29,13 @@ /* Returns a pointer to the entry in ENVZ for NAME, or 0 if there is none.
