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
13 **** See http://www.gnu.org/software/libc/porting.html for more details.
16 [ 2] Test compliance with standards. If you have access to recent
17 standards (IEEE, ISO, ANSI, X/Open, ...) and/or test suites you
18 could do some checks as the goal is to be compliant with all
19 standards if they do not contradict each other.
22 [ 3] Write translations for the GNU libc message for the so far
23 unsupported languages. GNU libc is fully internationalized and
24 users can immediately benefit from this.
26 Take a look at the matrix in
27 ftp://prep.ai.mit.edu/pub/gnu/ABOUT-NLS
28 for the current status (of course better use a mirror of prep).
31 [ 4] Write wordexp() function; this is described in POSIX.2, the
32 header <wordexp.h> already exists.
34 Implementation idea: use some functions from bash.
36 **** Somebody is working on this. Help may or may not be appreciated.
39 [ 5] Write `long double' versions of the math functions. This should be
40 done in collaboration with the NetBSD and FreeBSD people.
42 The libm is in fact fdlibm (not the same as in Linux libc).
44 **** Partly done. But we need someone with numerical experiences for
48 [ 6] If you enjoy assembler programming (as I do --drepper :-) you might
49 be interested in writing optimized versions for some functions.
50 Especially the string handling functions can be optimized a lot.
54 Faster String Functions
55 Henry Spencer, University of Toronto
56 Usenix Winter '92, pp. 419--428
58 or just ask. Currently mostly i?86 and Alpha optimized versions
59 exist. Please ask before working on this to avoid duplicate
63 [ 7] Write nftw() function. Perhaps it might be good to reimplement the
64 ftw() function as well to share most of the code.
69 [ 8] Write AVL-tree based tsearch() et.al. functions. Currently only
70 a very simple algorithm is used.
71 There is a public domain version but using this would cause problems
75 [ 9] Extend regex and/or rx to work with wide characters and complete
76 implementation of character class and collation class handling.
78 It is planed to do a complete rewrite.
81 [10] Write access function for netmasks, bootparams, and automount
82 databases for nss_files and nss_db module.
83 The functions should be embedded in the nss scheme. This is not
84 hard and not all services must be supported at once.
87 [11] Rewrite utmp/wtmp functions to use database functions. This is much
88 better than the normal flat file format.
90 **** There are plans for a new approach to this problem. Please contact
91 bug-glibc@prep.ai.mit.edu before starting to work.)
94 [12] Several more or less small functions have to be written:
96 + tcgetid() and waitid() from XPG4.2
97 + grantpt(), ptsname(), unlockpt() from XPG4.2
98 + getdate() from XPG4.2
