From 2303f5fdd96d7bec2dea11b41cc0c07eddd50979 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 10 Nov 1996 02:21:51 +0000 Subject: update from main archive 961109 Sun Nov 10 02:37:15 1996 Ulrich Drepper * inet/gethstent_r.c: Update copyright. * nss/getXXbyYY_r.c: Likewise. * nss/nsswitch.c: Likewise. * nss/getXXent_r.c: Likewise. * nss/nss_files/files-XXX.c: Likewise. * nss/nss_files/files-netgroup.c: Likewise. * nss/nss_files/files-parse.c: Likewise. * nss/getXXent_r.c: Change implementation. It's not necessary to call all setXXent functions. Just find first available and when necessary let getXXent_r call the others. * nss/nss_files/files-XXX.c: Make really reentrant. Now calls of getXXent and getXXbyYY can be mixed. The cursor for traversing the database with getXXent will be remembered. * stdlib/test-canon.c (cwd): Change size to PATH_MAX. Sat Nov 9 15:34:48 1996 Ulrich Drepper * sysdeps/unix/sysv/linux/Dist: Add sys/mtio.h. * sysdeps/unix/sysv/linux/sys/mtio.h: New file. * signal/signal.h [__USE_BSD]: Add prototype for siggetmask. Fri Nov 8 13:29:30 1996 Ulrich Drepper * ctype/ctype.h (__isascii): Don't test for seventh bit not to be set. Instead for none beside the first seven bits to be set. X/Open allows the argument to be an `int' value. Reported by Alain Williams . (toascii, isascii): Define macro also when __USE_XOPEN. * sysdeps/posix/fpathconf.c: Use fstatfs to compute NAME_MAX, not PATH_MAX. Thu Nov 7 03:04:29 1996 Ulrich Drepper * nss/getXXXent_r.c (SETFUNC_NAME): Reset `nip' after loop to NULL so that GETFUNC will see first entry. (ENDFUNC_NAME): Likewise. Rewrite Netgroups implementation to avoid global data. * inet/netgroup.h: Add definition of name_list and struct __netgrent. Add prototypes for internal netgroup functions. * nss/nss_files/files-netgroup.c (_nss_files_setnetgrent): Take extra argument and use the included data instead of global vars. (_nss_files_endnetgrent): Likewise. (_nss_netgroup_parseline): Change to be static and use data included in the RESULT structure. * inet/getnetgrent_r.c (startp): Move into setup function. (known_groups, needed_groups): new part of the __netgrent sruct. (freememory): Take extra argument and use included data. (__internal_endnetgrent): Likewise. (internal_setnetgrent): Renamed to __internal_setnetgrent_reuse and take extra argument. (__internal_setnetgrent): New function. Call __internal_setnetgrent_reuse after calling free_memory. (setnetgrent): Only call __internal_setnetgrent. (__getnetgrent_r): Split into two functions. __getnetgrent_r calls __internal_getnetgrent after locking. (innetgr): Use dynamic data only. I.e., innetgr now is fully reentrant. Thu Nov 7 00:15:14 1996 Ulrich Drepper * sysdeps/stub/setenv.c: Correct typo: unseenv -> unsetenv. Reported by Joshua Cowan . Wed Nov 6 13:13:37 1996 Ulrich Drepper * manual/creature.texi: Document that _GNU_SOURCE is no longer the default when no *_SOURCE macro is given. Reported by Karsten Weiss . * NOTES: remade from manual/creature.texi. * manual/libc.texinfo: Add back line about GPL translation which somehow got lost. * Make-dist (dist.tar): Depend on README being updated. * rellns-sh: Correct thinko in removing leading /. Reported by Andreas Jaeger . * pwd/fgetpwent_r.c: Recognize lines containing only names starting with `+' or `-' in parser. * grp/fgetgrent_r.c: Likewise. * shadow/sgetspent_r.c: Likewise. * nss/nss_files/files-spwd.c: Don't accept entries starting with `+' or `-'. * sysdeps/stub/lchown.c: New file. --- nss/nss_files/files-XXX.c | 60 ++++++++++++++++++++++++++++++++++------------- 1 file changed, 44 insertions(+), 16 deletions(-) (limited to 'nss/nss_files/files-XXX.c') diff --git a/nss/nss_files/files-XXX.c b/nss/nss_files/files-XXX.c index 404a9f9750..b6702b0366 100644 --- a/nss/nss_files/files-XXX.c +++ b/nss/nss_files/files-XXX.c @@ -1,21 +1,21 @@ /* Common code for file-based databases in nss_files module. -Copyright (C) 1996 Free Software Foundation, Inc. -This file is part of the GNU C Library. + Copyright (C) 1996 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.
