From a18f587da5a0a91bcd1307ed0f122ca2ce994c15 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 7 Dec 1996 03:30:25 +0000 Subject: update from main archive 961206 Sat Dec 7 03:24:36 1996 Ulrich Drepper * configure.in: Discard error message from test in test for bash-2.0. * io/getpw.c: Don't apply getcwd on user supplied buffer. Instead always use temporary buffer and only copy the result. Patch by HJ Lu. * stdlib/canonicalize.c: Likewise. * libio/fileops.c: Change comments according to libg++2.8b5. * libio/iosetvbuf.c: Follow change in libg++-2.8b5 to clear unbuffered flag. Reported by HJ Lu. * manual/nss.texi: Correct prototypes. * misc/syslog.c: Make reentrant. Catch SIGPIPE signal to prevent crash if syslog daemon is restarted. * stdlib/rand_r.c: New file. Implementation of POSIX.2 function rand_r. * stdlib/Makefile (routines): Add rand_r. * sysdeps/stub/libc-lock.h: Define __libc_lock_trylock and __libc_mutex_lock. * configure.in: Add --disable-sanity-check option. * sysdeps/unix/sysv/linux/configure.in: If linuxthreads or des-crypt are not available and --disbale-sanity-check is not given abort with a message. Thu Dec 5 19:19:53 1996 Richard Henderson * posix/glob.c: Tests against STDC_HEADERS should also test __GNU_LIBRARY__. Thu Dec 5 16:20:55 1996 Ulrich Drepper * misc/err.c (vwarn): Set errno again before using %m format. Thu Dec 5 10:14:05 1996 Andreas Jaeger * grp/grp.h: Add declaration of __getgrent_r. * io/fts.c (fts_build): Remove "register" from variables dirbuf and dp since their address is needed. * sysdeps/posix/getcwd.c (__getcwd): Remove "register" from variable d since d's address is needed. * misc/tst-dirname.c (main): Provide prototype. * misc/ioctltst.c (main): Dito. * Makefile: Add gnu/lib-names.h to install-others before including Makerules. Wed Dec 4 16:00:09 1996 Ulrich Drepper * sysdeps/unix/sysv/linux/sys/socketvar.h: New file. Simply use . * sysdeps/unix/sysv/linux/Dist: Add sys/socketvar.h. * sysdeps/unix/sysv/linux/Makefile [$(subdir)=inet)]: Add sys/socketvar.h to sysdep_headers. since the value might be outside the range of the `long int'. --- sysdeps/posix/getcwd.c | 2 +- sysdeps/stub/libc-lock.h | 6 ++++ sysdeps/unix/sysv/linux/Dist | 1 + sysdeps/unix/sysv/linux/Makefile | 2 +- sysdeps/unix/sysv/linux/alpha/llseek.S | 60 --------------------------------- sysdeps/unix/sysv/linux/configure | 53 +++++++++++++---------------- sysdeps/unix/sysv/linux/configure.in | 47 ++++++++++++++++++++++++++ sysdeps/unix/sysv/linux/sys/socketvar.h | 3 ++ 8 files changed, 82 insertions(+), 92 deletions(-) delete mode 100644 sysdeps/unix/sysv/linux/alpha/llseek.S create mode 100644 sysdeps/unix/sysv/linux/sys/socketvar.h (limited to 'sysdeps') diff --git a/sysdeps/posix/getcwd.c b/sysdeps/posix/getcwd.c index 92196ac50a..4ea90a7320 100644 --- a/sysdeps/posix/getcwd.c +++ b/sysdeps/posix/getcwd.c @@ -253,7 +253,7 @@ __getcwd (buf, size) while (!(thisdev == rootdev && thisino == rootino)) { register DIR *dirstream; - register struct dirent *d; + struct dirent *d; #if defined HAVE_READDIR_R || defined _LIBC struct dirent dirbuf; #endif diff --git a/sysdeps/stub/libc-lock.h b/sysdeps/stub/libc-lock.h index 158a221718..d0a82fea21 100644 --- a/sysdeps/stub/libc-lock.h +++ b/sysdeps/stub/libc-lock.h @@ -48,6 +48,9 @@ /* Lock the named lock variable. */ #define __libc_lock_lock(NAME) +/* Try tp lock the named lock variable. */ +#define __libc_lock_trylock(NAME) + /* Unlock the named lock variable. */ #define __libc_lock_unlock(NAME) @@ -58,4 +61,7 @@ #define __libc_cleanup_region_end(DOIT) +/* We need protable names for some of the functions. */ +#define __libc_mutex_unlock + #endif /* libc-lock.h */ diff --git a/sysdeps/unix/sysv/linux/Dist b/sysdeps/unix/sysv/linux/Dist index 0adc370632..40f65b838c 100644 --- a/sysdeps/unix/sysv/linux/Dist +++ b/sysdeps/unix/sysv/linux/Dist @@ -22,6 +22,7 @@ sys/mtio.h sys/procfs.h sys/quota.h sys/socketcall.h +sys/socketvar.h sys/soundcard.h sys/sysctl.h sys/sysinfo.h diff --git a/sysdeps/unix/sysv/linux/Makefile b/sysdeps/unix/sysv/linux/Makefile index c7cf1f9570..c03d966a61 100644 --- a/sysdeps/unix/sysv/linux/Makefile +++ b/sysdeps/unix/sysv/linux/Makefile @@ -51,7 +51,7 @@ inhibit-siglist := yes endif ifeq ($(subdir), inet) -sysdep_headers += netinet/in_systm.h +sysdep_headers += netinet/in_systm.h sys/socketvar.h endif # Don't compile the ctype glue code, since there is no old non-GNU C library. diff --git a/sysdeps/unix/sysv/linux/alpha/llseek.S b/sysdeps/unix/sysv/linux/alpha/llseek.S deleted file mode 100644 index a2e644c161..0000000000 --- a/sysdeps/unix/sysv/linux/alpha/llseek.S +++ /dev/null @@ -1,60 +0,0 @@ -/* Copyright (C) 1993, 1995, 1996 Free Software Foundation, Inc. - This file is part of the GNU C Library. - Contributed by David Mosberger , 1995. - - 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.
