update from main archive 961109
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.
