Ulrich Drepper a3e59be8d1 Update.
Mon Aug 12 03:31:58 1996  Ulrich Drepper  <drepper@cygnus.com>

	* nss/nsswitch.c (__nss_configure_lookup):  New function.
	Allows to specify services.
	* nss/XXX-lookup.h: Rename database variable and make global.
	* nss/databases.def: New file.  Real names of all databases.

	* nss/nss.h: New file.  Contains declaration useful for users
	and service developers.
	* nss/nsswitch.h: Move some declarations to nss/nss.h.
	* nss.h: New file.  Wrapper around nss/nss.h.

	* nss/Makefile (headers): Add nss.h.
	(distributes): Add databases.h.

Sun Aug 11 16:19:42 1996  Ulrich Drepper  <drepper@cygnus.com>

	Help the poor people with fast machines by making sure only
	one `ar' commands works on the library.
	* autolock.sh: New file.  Written by Tom Tromey.
	* Makerules (do-ar): Call autolock.sh shell script instead of
	directly using `ar'.
	* config.make.in: Make configuration variable AUTOLOCK which
	gets initialized by configure.
	* configure.in: Define variable AUTOLOCK to point to autolock.sh
	script and mark it to substitute.

	* string/Makefile: Add -fno-builtin for tst-strlen.c, too.

	* elf/dl-lookup.c (_dl_lookup_symbol): Allow self-referencing.
	Patch by David Mosberger-Tang.

Sun Aug 11 01:12:38 1996  Richard Henderson  <rth@tamu.edu>

	* sysdeps/alpha/dl-machine.h (elf_alpha_fix_plt): Optimize LD_BIND_NOW
	startup by moving Icache flush from here ...
	(ELF_MACHINE_RUNTIME_TRAMPOLINE): ... to here.
	(ELF_MACHINE_USER_ADDRESS_MASK): Delete; it is unused.

	* sysdeps/alpha/divrem.h: Update comment to reflect the actual
	calling conventions.  The code is already correct.

Sun Aug 11 01:06:42 1996  Richard Henderson  <rth@tamu.edu>

	* string/Makefile: Compile tester with -fno-builtin as we want to
	test our implementations, not gcc's.

Open jobs for finishing GNU libc:
---------------------------------
Status: July 1996
If you have time and talent to take over any of the jobs below please
contact <bug-glibc@prep.ai.mit.edu>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[ 1] Port to new platforms or test current version on formerly supported
platforms.
[ 2] Test compliance with standards. If you have access to recent
standards (IEEE, ISO, ANSI, X/Open, ...) and/or test suites you
could do some checks as the goal is to be compliant with all
standards if they do not contradict each other.
[ 3] Write translations for the GNU libc message for the so far
unsupported languages. GNU libc is fully internationalized and
users can immediately benefit from this.
Take a look at the matrix in
ftp://prep.ai.mit.edu/pub/gnu/ABOUT-NLS
for the current status (of course better use a mirror of prep).
[ 4] Write wordexp() function; this is described in POSIX.2, The
header <wordexp.h> already exists.
Implementation idea: use some functions from bash.
[ 5] Write reentrant versions of crypt() et.al.
Implementation idea: Define in <crypt.h>
struct crypt_data
{
<... all the needed data ...>
};
and define additional functions
char *crypt_r (__const char *__key, __const char *__salt,
struct crypt_data *__data);
void setkey_r (__const char *__key, struct crypt_data *__data);
void encrypt_r (char *__block, int __edflag,
struct crypt_data *__data);
If possible the non-reentrant functions should use the reentrant
ones.
Because of the US export restrictions it might be a good idea if
some non-american person does this job.
[ 6] Write `long double' versions of the math functions. This should be
done in collaboration with the NetBSD and FreeBSD people.
The libm is in fact fdlibm (not the same as in Linux libc).
**** Partly done.
[ 7] If you enjoy assembler programming (as I do --drepper :-) you might
be interested in writing optimized versions for some functions.
Especially the string handling functions can be optimized a lot.
Take a look at
Faster String Functions
Henry Spencer, University of Toronto
Usenix Winter '92, pp. 419--428
or just ask. Currently mostly i?86 optimized versions exist.
Alpha versions are on their way, so please ask before working
on this.
[ 8] Write nftw() function. Perhaps it might be good to reimplement the
ftw() function as well to share most of the code.
**** Almost done!
[ 9] Write AVL-tree based tsearch() et.al. functions. Currently only
a very simple algorithm is used.
There is a public domain version but using this would cause problems
with the assignment.
[10] Extend regex and/or rx to work with wide characters.
[11] Add mmap() support to malloc().
Doug Lea's malloc implementation might give some ideas. Perhaps
switching completly to his implementation is an option if it
a) can work without mmap() support (not all system GNU libc
is running on have mmap)
b) is without mmap support at least as fast as the current
implementation
c) will be extended with the current hooks and additional functions
Please contact bug-glibc@prep.ai.mit.edu before starting to avoid
duplicated work.
[12] Write access function for netmasks, bootparams, netgroup, publickey,
automount, aliases databases for nss_files and nss_db module.
The functions should be embedded in the nss scheme. This is not
hard and not all services must be supported at once.
