From fc5f4a97487fffc7f5451d216f278d83a8259efe Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 9 Sep 2000 07:59:23 +0000 Subject: Update. 2000-09-09 Ulrich Drepper * sysdeps/unix/sysv/linux/dl-osinfo.h (DL_SYSDEP_OSCHECK): Use uname before trying to read /proc. Patch by Matt Wilson . * include/sys/utsname.h: Declare __uname. * sysdeps/generic/uname.c: Make uname a weak alias of __uname. * sysdeps/mach/hurd/uname.c: Likewise. * sysdeps/unix/syscalls.list: Likewise. * iconv/gconv_dl.c (do_release_shlib): Rewrite condition for unloading a bit. 2000-09-08 Ulrich Drepper * posix/getopt.c (_getopt_internal): When long_only is set always recognize conflicts just like before. 2000-09-08 Franz Sirl * sysdeps/ia64/Makefile (sysdep-rtld-routines): New variable. --- ChangeLog | 22 ++++++++++++++++++++++ iconv/gconv_dl.c | 15 ++++++--------- include/sys/utsname.h | 4 ++++ posix/getopt.c | 3 ++- sysdeps/generic/uname.c | 5 +++-- sysdeps/mach/hurd/uname.c | 5 +++-- sysdeps/unix/syscalls.list | 2 +- sysdeps/unix/sysv/linux/dl-osinfo.h | 30 ++++++++++++++++++++---------- 8 files changed, 61 insertions(+), 25 deletions(-) diff --git a/ChangeLog b/ChangeLog index 399a35e..56d1700 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,25 @@ +2000-09-09 Ulrich Drepper + + * sysdeps/unix/sysv/linux/dl-osinfo.h (DL_SYSDEP_OSCHECK): Use uname + before trying to read /proc. + Patch by Matt Wilson . + * include/sys/utsname.h: Declare __uname. + * sysdeps/generic/uname.c: Make uname a weak alias of __uname. + * sysdeps/mach/hurd/uname.c: Likewise. + * sysdeps/unix/syscalls.list: Likewise. + + * iconv/gconv_dl.c (do_release_shlib): Rewrite condition for + unloading a bit. + +2000-09-08 Ulrich Drepper + + * posix/getopt.c (_getopt_internal): When long_only is set always + recognize conflicts just like before. + +2000-09-08 Franz Sirl + + * sysdeps/ia64/Makefile (sysdep-rtld-routines): New variable. + 2000-09-08 Greg McGary * sysdeps/unix/sysv/linux/syscalls.list (mincore): Fix arg signature. diff --git a/iconv/gconv_dl.c b/iconv/gconv_dl.c index 308db52..114619e 100644 --- a/iconv/gconv_dl.c +++ b/iconv/gconv_dl.c @@ -110,6 +110,7 @@ __gconv_find_shlib (const char *name) { if (found->counter < -TRIES_BEFORE_UNLOAD) { + assert (found->handle == NULL); found->handle = __libc_dlopen (found->name); if (found->handle != NULL) { @@ -162,16 +163,12 @@ do_release_shlib (const void *nodep, VISIT value, int level) assert (obj->counter > 0); --obj->counter; } - else if (obj->counter <= 0) + else if (obj->counter <= 0 && obj->counter >= -TRIES_BEFORE_UNLOAD + && --obj->counter < -TRIES_BEFORE_UNLOAD && obj->handle != NULL) { - if (obj->counter >= -TRIES_BEFORE_UNLOAD) - --obj->counter; - if (obj->counter < -TRIES_BEFORE_UNLOAD && obj->handle != NULL) - { - /* Unload the shared object. */ - __libc_dlclose (obj->handle); - obj->handle = NULL; - } + /* Unload the shared object. */ + __libc_dlclose (obj->handle); + obj->handle = NULL; } } diff --git a/include/sys/utsname.h b/include/sys/utsname.h index ff81bdf..39ca7f5 100644 --- a/include/sys/utsname.h +++ b/include/sys/utsname.h @@ -1 +1,5 @@ +#ifndef _SYS_UTSNAME_H #include + +extern int __uname (struct utsname *__name); +#endif diff --git a/posix/getopt.c b/posix/getopt.c index 2ad4ee9..a6d2d04 100644 --- a/posix/getopt.c +++ b/posix/getopt.c @@ -673,7 +673,8 @@ _getopt_internal (argc, argv, optstring, longopts, longind, long_only) pfound = p; indfound = option_index; } - else if (pfound->has_arg != p->has_arg + else if (long_only + || pfound->has_arg != p->has_arg || pfound->flag != p->flag || pfound->val != p->val) /* Second or later nonexact match found. */ diff --git a/sysdeps/generic/uname.c b/sysdeps/generic/uname.c index 68335c2..aacb5f3 100644 --- a/sysdeps/generic/uname.c +++ b/sysdeps/generic/uname.c @@ -1,4 +1,4 @@ -/* Copyright (C) 1991, 1992, 1996, 1997 Free Software Foundation, Inc. +/* Copyright (C) 1991, 1992, 1996, 1997, 2000 Free Software Foundation, Inc.
