1 Open jobs for finishing GNU libc:
2 ---------------------------------
5 If you have time and talent to take over any of the jobs below please
6 contact <bug-glibc@prep.ai.mit.edu>
8 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
10 [ 1] Port to new platforms or test current version on formerly supported
14 [ 2] Test compliance with standards. If you have access to recent
15 standards (IEEE, ISO, ANSI, X/Open, ...) and/or test suites you
16 could do some checks as the goal is to be compliant with all
17 standards if they do not contradict each other.
20 [ 3] Write translations for the GNU libc message for the so far
21 unsupported languages. GNU libc is fully internationalized and
22 users can immediately benefit from this.
24 Take a look at the matrix in
25 ftp://prep.ai.mit.edu/pub/gnu/ABOUT-NLS
26 for the current status (of course better use a mirror of prep).
29 [ 4] Write wordexp() function; this is described in POSIX.2, the
30 header <wordexp.h> already exists.
32 Implementation idea: use some functions from bash.
35 [ 5] Write `long double' versions of the math functions. This should be
36 done in collaboration with the NetBSD and FreeBSD people.
38 The libm is in fact fdlibm (not the same as in Linux libc).
40 **** Partly done. But we need someone with numerical experiences for
44 [ 6] If you enjoy assembler programming (as I do --drepper :-) you might
45 be interested in writing optimized versions for some functions.
46 Especially the string handling functions can be optimized a lot.
50 Faster String Functions
51 Henry Spencer, University of Toronto
52 Usenix Winter '92, pp. 419--428
54 or just ask. Currently mostly i?86 and Alpha optimized versions
55 exist. Please ask before working on this to avoid duplicate
59 [ 7] Write nftw() function. Perhaps it might be good to reimplement the
60 ftw() function as well to share most of the code.
65 [ 8] Write AVL-tree based tsearch() et.al. functions. Currently only
66 a very simple algorithm is used.
67 There is a public domain version but using this would cause problems
71 [ 9] Extend regex and/or rx to work with wide characters and complete
72 implementation of character class and collation class handling.
74 It is planed to do a complete rewrite.
77 [10] Add mmap() support to malloc().
78 Doug Lea's malloc implementation might give some ideas. Perhaps
79 switching completly to his implementation is an option if it
80 a) can work without mmap() support (not all system GNU libc
81 is running on have mmap)
82 b) is without mmap support at least as fast as the current
84 c) will be extended with the current hooks and additional functions
86 Please contact bug-glibc@prep.ai.mit.edu before starting to avoid
90 [11] Write access function for netmasks, bootparams, publickey, automount,
91 and aliases databases for nss_files and nss_db module.
92 The functions should be embedded in the nss scheme. This is not
93 hard and not all services must be supported at once.
96 [12] Rewrite utmp/wtmp functions to use database functions. This is much
97 better than the normal flat file format.
99 Please contact bug-glibc@prep.ai.mit.edu before starting to avoid
