From 61eb22d3a8e9bb9c339bdbe907a85656823f4c7e Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 16 Sep 1997 00:42:43 +0000 Subject: Update. 1997-09-16 02:14 Ulrich Drepper Implementation of Hesiod NSS module by Mark Kettenis. * hesiod/Makefile: New file. * hesiod/hesiod.c: New file. * hesiod/hesiod.h: New file. * hesiod/hesiod_p.h: New file. * hesiod/libnss_hesiod.map: New file. * hesiod/nss_hesiod/hesiod-grp.c: New file. * hesiod/nss_hesiod/hesiod-pwd.c: New file. * hesiod/nss_hesiod/hesiod-service.c: New file. * sysdeps/unix/inet/Subdirs: Add hesiod. * shlib-versions: Add version number for libnss_hesiod. * libio/iolibio.h: Remove definition of _IO_* macros. * libio/fileops.c: Define close, fstat, lseek, read, and write as macros to use __ protected versions. Use those functions instead of _IO_* functions. * libio/iopopen.c: Define _IO_close to close. * manual/math.texi: Explain the use of the optimizing inline functions. Describe rand_r function and tell about SysV RNGs in introduction. * resolv/res_send.c (res_send): Use socklen_t type for `fromlen' variable. * string/Makefile (tests): Add noinl-tester. * string/noinl-tester.c: New file. * string/tester.c: Add more stpcpy tests for constant arguments for all short lengths. * string/string.h: Always declare __bzero. Describe __NO_STRING_INLINES. Always include . * string/bits/string2.h: Add warning about direct use. Change __strcpy_small and __stpcpy_small implementation to use macros and provide alternative for platforms which cannot do unaligned stores. * sysdeps/i386/bits/string.h: Don't define anything is __NO_STRING_INLINES is defined. * sysdeps/i386/i486/bits/string.h: Change __strcpy_small and __stpcpy_small implementation to use macros and provide alternative for platforms which cannot do unaligned stores. * sysdeps/alpha/bzero.S: Define bzero as weak alias of __bzero. * sysdeps/generic/bzero.c: Likewise. * sysdeps/i386/bzero.c: Likewise. * sysdeps/i386/i586/bzero.S: Likewise. * sysdeps/vax/bzero.s: Likewise. * sysdeps/generic/bits/select.h: Don't use ugly casts to access array. * sysdeps/i386/bits/select.h: Likewise. * sysdeps/i386/fpu/bits/mathinline.c (__finite): Relax register constraints a bit. Don't define and test for _BITS_MATHINLINE_H. Emit warning if used directly and not through math.h. * sysdeps/i386/i486/atomicity.h: Change return type of compare_and_swap to char to get better code. Fix typo. * sysdeps/stub/atomicity.h: Fix typo. 1997-09-14 Andreas Schwab * sysdeps/generic/stpcpy.c: #undef stpcpy and __stpcpy. 1997-09-14 Andreas Schwab * string/bits/string2.h: Add prototypes to avoid warning. 1997-09-14 Andreas Schwab * string/bits/string2.h (strsep): Fix handling of empty REJECT. (__strsep_1c): Handle NULL and empty string. (__strsep_g): Likewise. 1997-09-13 Andreas Schwab * catgets/Makefile (extra-objs): Set this instead of generated. * md5-crypt/Makefile (extra-objs): Add all object file variants of onlymd5-entry. 1997-09-12 Andreas Schwab * sysdeps/generic/sysd-stdio.c (__stdio_read): Fix typo in last change. 1997-09-12 Andreas Schwab * sysdeps/m68k/m68020/atomicity.h: New file. 1997-09-15 05:11 Ulrich Drepper * posix/Makefile (distribute): Add globtest.c and globtest.sh. Compile and run globtest if not cross-compiling. * posix/globtest.c: New file. * posix/globtest.sh: New file. * posix/glob.c: Pretty print preprocessor stuff. (glob_in_dir): If PATTERN is not really a pattern still check whether it is a real file in the current directory and return error if not. Reported by Eugene Mamchits . * libio/fileops.c (_IO_file_sync): Acquire lock before doing the work. * libio/ioseekoff.c (_IO_seekoff): Likewise. * libio/ioseekpos.c (_IO_seekpos): Likewise. 1997-09-13 18:06 Ulrich Drepper * configure.in: Prevent configuration for unsupported platforms. 1997-09-13 04:07 Ulrich Drepper * elf/rtld.c (dl_main): Make sure we always have a file argument by testing for < 2 arguments after recognizing the options. 1997-09-12 11:47 Fila Kolodny * string/bits/string2.h (__strsep_1c): Cast out const from __retval. (__strsep_g): Likewise. --- posix/glob.c | 269 +++++++++++++++++++++++++++++++++-------------------------- 1 file changed, 153 insertions(+), 116 deletions(-) (limited to 'posix/glob.c') diff --git a/posix/glob.c b/posix/glob.c index b6e087e5eb..f0cb6d377b 100644 --- a/posix/glob.c +++ b/posix/glob.c @@ -21,12 +21,12 @@ #endif #ifdef HAVE_CONFIG_H -#include +# include #endif /* Enable GNU extensions in glob.h. */ #ifndef _GNU_SOURCE -#define _GNU_SOURCE 1 +# define _GNU_SOURCE 1 #endif #include @@ -49,45 +49,45 @@ it is simpler to just do this in the source for each such file. */ #define GLOB_INTERFACE_VERSION 1 -#if !defined (_LIBC) && defined (__GNU_LIBRARY__) && __GNU_LIBRARY__ > 1 -#include -#if _GNU_GLOB_INTERFACE_VERSION == GLOB_INTERFACE_VERSION -#define ELIDE_CODE -#endif +#if !defined _LIBC && defined __GNU_LIBRARY__ && __GNU_LIBRARY__ > 1 +# include +# if _GNU_GLOB_INTERFACE_VERSION == GLOB_INTERFACE_VERSION +# define ELIDE_CODE +# endif #endif #ifndef ELIDE_CODE -#if defined(STDC_HEADERS) || defined(__GNU_LIBRARY__) -#include +#if defined STDC_HEADERS || defined __GNU_LIBRARY__ +# include #endif #if defined HAVE_UNISTD_H || defined _LIBC -#include -#ifndef POSIX -#ifdef _POSIX_VERSION -#define POSIX -#endif -#endif +# include +# ifndef POSIX +# ifdef _POSIX_VERSION +# define POSIX +# endif +# endif #endif -#if !defined (_AMIGA) && !defined (VMS) && !defined(WINDOWS32) -#include +#if !defined _AMIGA && !defined VMS && !defined WINDOWS32 +# include #endif -#if !defined(__GNU_LIBRARY__) && !defined(STDC_HEADERS) +#if !defined __GNU_LIBRARY__ && !defined STDC_HEADERS extern int errno; #endif #ifndef __set_errno -#define __set_errno(val) errno = (val) +# define __set_errno(val) errno = (val) #endif #ifndef NULL -#define NULL 0 +# define NULL 0 #endif -#if defined (HAVE_DIRENT_H) || defined (__GNU_LIBRARY__) +#if defined HAVE_DIRENT_H || defined __GNU_LIBRARY__ # include # define NAMLEN(dirent) strlen((dirent)->d_name) #else @@ -110,36 +110,36 @@ extern int errno; /* In GNU systems, defines this macro for us. */ #ifdef _D_NAMLEN -#undef NAMLEN -#define NAMLEN(d) _D_NAMLEN(d) +# undef NAMLEN +# define NAMLEN(d) _D_NAMLEN(d) #endif -#if (defined (POSIX) || defined (WINDOWS32)) && !defined (__GNU_LIBRARY__) +#if (defined POSIX || defined WINDOWS32) && !defined __GNU_LIBRARY__ /* Posix does not require that the d_ino field be present, and some systems do not provide it. */ -#define REAL_DIR_ENTRY(dp) 1 +# define REAL_DIR_ENTRY(dp) 1 #else -#define REAL_DIR_ENTRY(dp) (dp->d_ino != 0) +# define REAL_DIR_ENTRY(dp) (dp->d_ino != 0) #endif /* POSIX */ -#if (defined (STDC_HEADERS) || defined (__GNU_LIBRARY__)) -#include -#include -#define ANSI_STRING +#if defined STDC_HEADERS || defined __GNU_LIBRARY__ +# include +# include +# define ANSI_STRING #else /* No standard headers. */ extern char *getenv (); -#ifdef HAVE_STRING_H -#include -#define ANSI_STRING -#else -#include -#endif -#ifdef HAVE_MEMORY_H -#include -#endif +# ifdef HAVE_STRING_H +# include +# define ANSI_STRING +# else +# include +# endif +# ifdef HAVE_MEMORY_H +# include +# endif extern char *malloc (), *realloc (); extern void free (); @@ -151,35 +151,35 @@ extern void abort (), exit (); #ifndef ANSI_STRING -#ifndef bzero +# ifndef bzero extern void bzero (); -#endif -#ifndef bcopy +# endif +# ifndef bcopy extern void bcopy (); -#endif +# endif -#define memcpy(d, s, n) bcopy ((s), (d), (n)) -#define strrchr rindex +# define memcpy(d, s, n) bcopy ((s), (d), (n)) +# define strrchr rindex /* memset is only used for zero here, but let's be paranoid. */ -#define memset(s, better_be_zero, n) \ +# define memset(s, better_be_zero, n) \ ((void) ((better_be_zero) == 0 ?
