From 10dc2a90b7f86d9bc1be9d1b9305a781882f7ac5 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 18 Dec 1996 03:23:47 +0000 Subject: update from main archive 961217 Wed Dec 18 03:31:58 1996 Ulrich Drepper * dirent/scandir.c: Undo change from Mon Dec 2 15:32:15 1996. The stream is private and usages outside glibc don't care about reentrancy. * io/fts.c: Likewise. * io/ftw.c: Likewise. * sysdeps/posix/getcwd.c: Likewise. * sysdeps/posix/ttyname.c: Likewise. * sysdeps/posix/ttyname_r.c: Likewise. * sysdeps/posix/glob.c: Likewise. * libio/iovsprintf.c: Add cast to prevent warning. * libio/iovsscanf.c: Likewise. * libio/libioP.h: Define mmap to __mmap and munmap to __munmap to keep namespace clean. * new-malloc/malloc.c: Update to last version from Wolfram Gloger. Add hooks and check functions from old GNU malloc. * new-malloc/malloc.h: Likewise. * nis/ypclnt.c: Remove prototype for xdr_free. * snrpc/rpc/xdr.h: Add prototype for xdr_free. * manual/nss.texi: Correct description of default values and don't meantion NSS as an add-on. * nss/grp-lookup.c: Provide default value as "compat [NOTFOUND=return] files". * nss/pwd-lookup.c: Likewise. * nss/spwd-lookup.c: Likewise. * nss/network-lookup.c: Correct default to "dns [!UNAVAIL=return] files". * nss/nsswitch.c: Change default-default value to "nis [NOTFOUND=return] files" since compat is only available for group, passwd, and shadow. * stdlib/on_exit.c (on_exit): Rename to __on_exit and make old name a weak alias. * stdlib/stdlib.h: Add prototype for __on_exit. * sysdeps/unix/sysv/linux/schedbits.h: Add prototype for __clone. * time/Makefile: Undo change from Sun Dec 8 06:56:49 1996. The new malloc now has mcheck. * time/ap.c: Likewise. * time/tzset.c (__tzset): Rename to __tzset_internal. (tzset): Rename to __tzset. Make tzset a weak alias for __tzset. * time/localtime.c: Use __tzset_internal not __tzset. * time/strftime.c [_LIBC]: Define tzname as __tzname and tzset as __tzset to prevent namespace pollution. * wctype/iswctype.h (icwctype): Rename to __iswctype. Make iswctype a weak alias of __iswctype. * wctype/wctype.h: Add prototype for __iswctype. (iswalnum, iswalpha, iswcntrl, iswdigit, iswlower, iswgraph, iswprint, iswpunct, iswspace, iswupper, iswxdigit, iswblank): Use __iswctype for the test, not iswctype. 1996-12-16 Paul Eggert * hurd/hurd/sigpreempt.h (struct hurd_signal_preemptor.preemptor, _hurdsig_preemptors), hurd/hurd/signal.h (struct hurd_sigstate.preemptors), hurd/hurdfault.c, hurd/hurdfault.h (_hurdsig_fault_preemptor), hurd/hurdsig.c (_hurdsig_preempters): Renamed to fix spelling from `preempter' to `preemptor'. All uses changed. 1996-12-15 Paul Eggert * ctime.c (ctime): Return asctime (localtime (t)), as the C standard requires. Tue Dec 17 02:05:48 1996 Thomas Bushnell, n/BSG * sysdeps/mach/libc-lock.h (__libc_lock_trylock): Invert return value because Mach/cthreads uses the opposite convention from Posix/glibc. Mon Dec 16 22:41:01 1996 Ulrich Drepper * stdio-common/fcloseall.c: Correct test of already_called. Reported by Thomas Bushnell, n/BSG. Mon Dec 16 14:52:07 1996 Thomas Bushnell, n/BSG * mach/lock-intern.h (__mutex_try_lock): New function. Sun Dec 15 16:33:44 1996 Andreas Schwab * termios/sys/ttydefaults.h (TTYDEF_OFLAG): Only use OXTABS if defined, else XTABS. (CEOL, CSTATUS): Use _POSIX_VDISABLE if defined. Sun Dec 15 11:56:19 1996 Andreas Schwab * sysdeps/unix/sysv/linux/m68k/mremap.S: New file. * sysdeps/unix/sysv/linux/m68k/Dist: Distribute it. * sysdeps/unix/sysv/linux/m68k/Makefile (sysdep_routines): Add mremap. --- time/Makefile | 4 ---- time/ap.c | 2 -- time/ctime.c | 9 +++------ time/localtime.c | 34 +++++++++++++++++++--------------- time/strftime.c | 2 ++ time/tzset.c | 14 ++++++-------- 6 files changed, 30 insertions(+), 35 deletions(-) (limited to 'time') diff --git a/time/Makefile b/time/Makefile index e55b6641d3..966d9f2790 100644 --- a/time/Makefile +++ b/time/Makefile @@ -146,7 +146,3 @@ CFLAGS-zic.c = -Wno-strict-prototypes -DNOID $(tz-cflags) CFLAGS-ialloc.c = -Wno-strict-prototypes -DNOID CFLAGS-scheck.c = -Wno-strict-prototypes -DNOID CFLAGS-tzfile.c = $(tz-cflags) - -ifeq ($(malloc),new-malloc) -CFLAGS-ap.c = -DNO_MCHECK -endif diff --git a/time/ap.c b/time/ap.c index 9c1c0b3693..5319763384 100644 --- a/time/ap.c +++ b/time/ap.c @@ -29,9 +29,7 @@ main (int argc, char **argv) char buf[20]; time_t t; -#ifndef NO_MCHECK mcheck (NULL); -#endif if (argc != 1) fprintf(stderr, "Usage: %s\n", argv[0]); diff --git a/time/ctime.c b/time/ctime.c index f13d00e551..4f06f1e533 100644 --- a/time/ctime.c +++ b/time/ctime.c @@ -27,10 +27,7 @@ char * ctime (const time_t *t) { - static char buf[64]; /* POSIX.1 suggests at least 26 bytes. */ - struct tm tm; - struct tm *tp = __localtime_r (t, &tm); - if (tp == NULL) - return NULL; - return __asctime_r (tp, buf); + /* The C Standard says ctime (t) is equivalent to asctime (localtime (t)). + In particular, ctime and asctime must yield the same pointer. */ + return asctime (localtime (t)); } diff --git a/time/localtime.c b/time/localtime.c index 833d708b8d..5e1dd0a5b5 100644 --- a/time/localtime.c +++ b/time/localtime.c @@ -1,21 +1,21 @@ /* localtime -- convert `time_t' to `struct tm' in local time zone -Copyright (C) 1991, 92, 93, 95, 96 Free Software Foundation, Inc. -This file is part of the GNU C Library. + Copyright (C) 1991, 92, 93, 95, 96 Free Software Foundation, Inc. + This file is part of the GNU C Library. -The GNU C Library is free software; you can redistribute it and/or -modify it under the terms of the GNU Library General Public License as -published by the Free Software Foundation; either version 2 of the -License, or (at your option) any later version. + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public License as + published by the Free Software Foundation; either version 2 of the + License, or (at your option) any later version. -The GNU C Library is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
