1997-05-31 02:33 Ulrich Drepper <drepper@cygnus.com> * io/ftwtest-sh: More tests. * misc/tsearch.c: Rewrite tdestroy_recursive. * libio/libio.h: Define bits for libg++-2.8. 1997-05-30 22:21 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/nss_nis/nis-hosts.c: Same changes as in nss/nss_files/files-hosts.c (Always use inet_pton). * nis/nss_nisplus/nisplus-hosts.c: Likewise. 1997-05-30 09:50 Richard Henderson <rth@tamu.edu> * manual/maint.texi: ECOFF hasn't been tested in ages and I don't plan on doing so ever again. Don't say alpha-linuxecoff is known to work. * elf/dl-lookup.c: Include <alloca.h>. * misc/tsearch.c: Include <string.h>. * posix/execle.c: Include <alloca.h>. * posix/execlp.c: Likewise. * stdio-common/printf_fphex.c: Include <string.h>. * sunrpc/xdr.c: Include <string.h>. * sysdeps/generic/memccpy.c: Include only <string.h>. * sunrpc/clnt_udp.c (clntudp_call): Make fromlen a size_t to fix parameters to network functions. * sunrpc/pmap_rmt.c (clnt_broadcast): Likewise. * sunrpc/svc_tcp.c (svctcp_create): Likewise with `len'. (rendezvous_request): Likewise. * sunrpc/svc_udp.c (svcudp_bufcreate): Likewise. (svcudp_recv): Similar, but go through a local variable. The old code used &xprt->xp_addrlen. Someone should determine if the type of the structure member should be changed instead. * sunrpc/xdr_rec.c (xdrrec_create): Expunge a ptr->int cast warning and transform a nonsense for-loop to a closed form calculation. (fill_input_buf): Another ptr->int warning. * sysdeps/alpha/Makefile: Temporarily turn on -mieee globally. This will last until I figure out how to build a parallel libm_ieee. * sysdeps/alpha/fpu/fclrexcpt.c, * sysdeps/alpha/fpu/fegetenv.c, * sysdeps/alpha/fpu/fegetround.c, * sysdeps/alpha/fpu/feholdexcpt.c, * sysdeps/alpha/fpu/fenvbits.h, * sysdeps/alpha/fpu/fesetenv.c, * sysdeps/alpha/fpu/fesetround.c, * sysdeps/alpha/fpu/feupdateenv.c, * sysdeps/alpha/fpu/fgetexcptflg.c, * sysdeps/alpha/fpu/fraiseexcpt.c, * sysdeps/alpha/fpu/fsetexcptflg.c, * sysdeps/alpha/fpu/ftestexcept.c: New files. There is, btw, a small kernel patch that must be applied as of 2.0.31-pre1 and 2.1.41 for this to work properly. * sysdeps/alpha/fpu/fpu_control.h: Update copyright. Change default FP mode to round to nearest, no exceptions as for Intel. * sysdeps/unix/sysv/linux/alpha/setfpucw.c: Add copyright. (rdfpcr): Use excb rather than trapb. Be more efficient about getting at the fpcr. (wrfpcr): Likewise. (__setfpucw): Reformat. * sysdeps/ieee754/huge_val.h: Change GCC's HUGE_VAL definition to use a single DI-mode integer instead of bytes. This produces better code on Alpha. Similar for HUGE_VALF. * sysdeps/ieee754/nan.h: Similar for NAN. Add NANF and NANL. * sysdeps/libm-ieee754/s_log2.c: Missing */ and weak_alias. * sysdeps/unix/alpha/sysdep.S: Tiny cleanups. * sysdeps/unix/sysv/linux/alpha/syscall.S: Likewise. * sysdeps/unix/sysv/linux/alpha/brk.S: Don't use jmp macro to make sure the stack frame is released the very instruction before the real jump out. * sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S: Likewise. * sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S: Likewise. * sysdeps/unix/sysv/linux/alpha/gnu/types.h: Undef some bits we may have gotten from <linux/posix_types.h>. * sysdeps/unix/sysv/linux/alpha/ioperm.c: Add definition for Miata. 1997-05-30 13:05 Ulrich Drepper <drepper@cygnus.com> * misc/tst-tsearch.c (mangle_tree): Update casts to prevent warnings. 1997-05-29 14:02 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/sys/ttydefaults.h (CEOL, CSTATUS): Use correct value for _POSIX_VDISABLE. 1997-05-29 13:59 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * Makefile (manual/dir-add.texi): Force execution. 1997-05-29 13:57 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysexits.h: New file. 1997-05-29 13:55 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * stdlib/strfmon.c: Don't run past EOS after `='. 1997-02-27 10:34 Richard Henderson <rth@tamu.edu>

Open jobs for finishing GNU libc:
|
||
---------------------------------
|
||
Status: April 1997
|
||
|
||
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.
|
||
|
||
**** See http://www.gnu.org/software/libc/porting.html for more details.
|
||
|
||
|
||
[ 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] The IMHO opinion most important task is to write a more complete
|
||
test suite. We cannot get too many people working on this. It is
|
||
not difficult to write a test, find a definition of the function
|
||
which I normally can provide, if necessary, and start writing tests
|
||
to test for compliance. Beside this, take a look at the sources
|
||
and write tests which in total test as many paths of execution as
|
||
possible.
|
||
|
||
|
||
[ 4] 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).
|
||
|
||
|
||
[ 5] Write wordexp() function; this is described in POSIX.2, the
|
||
header <wordexp.h> already exists.
|
||
|
||
Implementation idea: use some functions from bash.
|
||
|
||
**** Somebody is working on this. Help may or may not be appreciated.
|
||
|
||
|
||
[ 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. But we need someone with numerical experiences for
|
||
the rest.
|
||
|
||
|
||
[ 7] Several math functions have to be written:
|
||
|
||
- exp2
|
||
|
||
each with float, double, and long double arguments.
|
||
|
||
Beside this most of the complex math functions which are new in
|
||
ISO C 9X should be improved. Writing some of them in assembler is
|
||
useful to exploit the parallelism which often is available.
|
||
|
||
|
||
[ 8] 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 and Alpha optimized versions
|
||
exist. Please ask before working on this to avoid duplicate
|
||
work.
|
||
|
||
|
||
[10] Extend regex and/or rx to work with wide characters and complete
|
||
implementation of character class and collation class handling.
|
||
|
||
It is planed to do a complete rewrite.
|
||
|
||
|
||
[11] Write access function for netmasks, bootparams, and automount
|
||
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.
|
||
|
||
|
||
[13] Several more or less small functions have to be written:
|
||
|
||
+ tcgetid() and waitid() from XPG4.2
|
||
+ grantpt(), ptsname(), unlockpt() from XPG4.2
|
||
+ getdate() from XPG4.2
|
||
*** Probably underway
|
||
|
||
More information are available on request.
|
||
|
||
|
||
[14] We need to write a library for on-the-fly transformation of streams
|
||
of text. In fact, this would be a recode-library (you know, GNU recode).
|
||
This is needed in several places in the GNU libc and I already have
|
||
rather concrete plans but so far no possibility to start this.
|
||
|
||
|
||
[15] Cleaning up the header files. Ideally, each header style should
|
||
follow the "good examples". Each variable and function should have
|
||
a short description of the function and its parameters. The prototypes
|
||
should always contain variable names which can help to identify their
|
||
meaning; better than
|
||
|
||
int foo __P ((int, int, int, int));
|
||
|
||
Blargh!
