update from main archive 961109cvs/libc-961110
Sun Nov 10 02:37:15 1996 Ulrich Drepper <drepper@cygnus.com> * 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 <drepper@cygnus.com> * 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 <drepper@cygnus.com> * 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 <addw@phcomp.co.uk>. (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 <drepper@cygnus.com> * 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 <drepper@cygnus.com> * sysdeps/stub/setenv.c: Correct typo: unseenv -> unsetenv. Reported by Joshua Cowan <jcowan@jcowan.reslife.okstate.edu>. Wed Nov 6 13:13:37 1996 Ulrich Drepper <drepper@cygnus.com> * manual/creature.texi: Document that _GNU_SOURCE is no longer the default when no *_SOURCE macro is given. Reported by Karsten Weiss <karsten@addx.au.s.shuttle.de>. * 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 <aj@arthur.pfalz.de>. * 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.
