Open jobs for finishing GNU libc:
|
|||
|
|
---------------------------------
|
|||
|
|
Status: May 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 reentrent 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-reentrent functions should use the reentrent
|
|||
|
|
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).
|
|||
|
|
|
|||
|
|
|
|||
|
|
[ 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.
|
|||
|
|
|
|||
|
|
|
|||
|
|
[ 8] Write nftw() function. Perhaps it might be good to reimplement the
|
|||
|
|
ftw() function as well to share most of the code.
|
|||
|
|
|
|||
|
|
|
|||
|
|
[ 9] Write AVL-tree based tsearch() et.al. functions. Currently only
|
|||
|
|
a very simple algorithm is used.
|
|||
|
|
|
|||
|
|
|
|||
|
|
[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
|
