Open jobs for finishing GNU libc: --------------------------------- Status: August 1997 If you have time and talent to take over any of the jobs below please contact ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ [ 1] Port to new platforms or test current version on formerly supported platforms. **** See http://www.gnu.org/software/libc/porting.html for more details. [ 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] The IMHO opinion most important task is to write a more complete test suite. We cannot get too many people working on this. It is not difficult to write a test, find a definition of the function which I normally can provide, if necessary, and start writing tests to test for compliance. Beside this, take a look at the sources and write tests which in total test as many paths of execution as possible. [ 4] 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). [ 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). **** Partly done. But we need someone with numerical experiences for the rest. [ 7] Several math functions have to be written: - exp2 each with float, double, and long double arguments. Beside this most of the complex math functions which are new in ISO C 9X should be improved. Writing some of them in assembler is useful to exploit the parallelism which often is available. [ 8] 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. [10] 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. [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. [13] Several more or less small functions have to be written: + tcgetid() and waitid() from XPG4.2 + grantpt(), ptsname(), unlockpt() from XPG4.2 More information is available on request. [14] We need to write a library for on-the-fly transformation of streams of text. In fact, this would be a recode-library (you know, GNU recode). This is needed in several places in the GNU libc and I already have rather concrete plans but so far no possibility to start this. [15] Cleaning up the header files. Ideally, each header style should follow the "good examples". Each variable and function should have a short description of the function and its parameters. The prototypes should always contain variable names which can help to identify their meaning; better than int foo __P ((int, int, int, int)); Blargh!
