Open jobs for finishing GNU libc:
---------------------------------
Status: October 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 `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.
[ 6] 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.
[ 7] Write nftw() function. Perhaps it might be good to reimplement the
ftw() function as well to share most of the code.
**** Almost done!
[ 8] 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.
[ 9] 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.
[10] 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.
[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.
[12] Rewrite utmp/wtmp functions to use database functions. This is much
better than the normal flat file format.
Please contact bug-glibc@prep.ai.mit.edu before starting to avoid
duplicated work.
