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@gnu.org>.
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] The IMHO opinion most important task is to write a more complete
23 test suite. We cannot get too many people working on this. It is
24 not difficult to write a test, find a definition of the function
25 which I normally can provide, if necessary, and start writing tests
26 to test for compliance. Beside this, take a look at the sources
27 and write tests which in total test as many paths of execution as
31 [ 4] Write translations for the GNU libc message for the so far
32 unsupported languages. GNU libc is fully internationalized and
33 users can immediately benefit from this.
35 Take a look at the matrix in
36 ftp://ftp.gnu.org/pub/gnu/ABOUT-NLS
37 for the current status (of course better use a mirror of ftp.gnu.org).
40 [ 8] If you enjoy assembler programming (as I do --drepper :-) you might
41 be interested in writing optimized versions for some functions.
42 Especially the string handling functions can be optimized a lot.
46 Faster String Functions

50 or just ask. Currently mostly i?86 and Alpha optimized versions
51 exist. Please ask before working on this to avoid duplicate
55 [11] Write access function for netmasks, bootparams, and automount
56 databases for nss_files, nss_nis, and nss_nisplus modules.
57 The functions should be embedded in the nss scheme. This is not
58 hard and not all services must be supported at once.
61 [15] Cleaning up the header files. Ideally, each header style should
62 follow the "good examples". Each variable and function should have
63 a short description of the function and its parameters. The prototypes
64 should always contain variable names which can help to identify their
67 int foo (int, int, int, int);
71 *** The conformtest.pl tool helps cleaning the namespace. As far as
72 known the prototypes all contain parameter names. But maybe some
73 comments can be improved.
76 [18] Based on the sprof program we need tools to analyze the output. The
77 result should be a link map which specifies in which order the .o
78 files are placed in the shared object. This should help to improve
79 code locality and result in a smaller footprint (in code and data
80 memory) since less pages are only used in small parts.
83 [19] A user-level STREAMS implementation should be available if the
84 kernel does not provide the support.
86 *** This is a much lower priority job now that STREAMS are optional in
90 [20] More conversion modules for iconv(3). Existing modules should be
91 extended to do things like transliteration if this is wanted.
92 For often used conversion a direct conversion function should be
96 [23] The `strptime' function needs to be completed. This includes among
97 other things that it must get teached about timezones. The solution
98 envisioned is to extract the timezones from the ADO timezone
99 specifications. Special care must be given names which are used
100 multiple times. Here the precedence should (probably) be according
101 to the geograhical distance. E.g., the timezone EST should be
102 treated as the `Eastern Australia Time' instead of the US `Eastern
103 Standard Time' if the current TZ variable is set to, say,
104 Australia/Canberra or if the current locale is en_AU.
