From 0200214b288810fc261b0b65c32f7068fcfa9b40 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 29 May 1996 04:48:04 +0000 Subject: Tue May 28 04:38:10 1996 Ulrich Drepper * limits.h: Change MB_LEN_MAX to 6. A 31-bit ISO 10646 character in UTF-8 encoding has that many bytes. * locale/langinfo.h: New element _NL_CTYPE_MB_CUR_MAX. * locale/categories.def: Add description of field _NL_CTYPE_MB_CUR_MAX. * locale/Makefile (routines): Add mb_cur_max. * locale/mb_cur_max.c: New file. This function gets called when the macro MB_CUR_MAX is used. * locale/C-ctype.c: Initialize new mb_cur_max field. * locale/localeinfo.h: Change magic value because of incompatible change. * locale/programs/ld-ctype.c: Determine value of mb_cur_max according to current character set and write it out with the rest. * stdlib/stdlib.h (MB_CUR_MAX): Not constant anymore. Get value according to currently used locale for catefory LC_CTYPE by calling the function __ctype_get_mb_cur_max. Tue May 28 03:27:46 1996 Ulrich Drepper * FAQ: Fix some typos. Tell that for Linux the kernel header files are necessary. * PROJECTS: New file. List of open jobs for glibc. * Makefile (distribute): Add PROJECTS. * crypt/GNUmakefile (headers): New variable. Mention crypt.h. * crypt/crypt.h: Header for crypt functions. * elf/elf.h: Add some new constants from recent Cygnus ELF header files. * login/getutid_r.c: Test for correct type. Don't depend on ut_type and ut_id unless _HAVE_UT_TYPE and _HAVE_UT_ID resp. are defined. Make really compliant with specification. * login/getutline_r.c, login/pututline_r.c: Don't depend on ut_type and ut_id unless _HAVE_UT_TYPE and _HAVE_UT_ID resp. are defined. Make really compliant with specification. * login/setutent_r.c: Don't depend on ut_type and ut_id unless _HAVE_UT_TYPE and _HAVE_UT_ID resp. are defined. * login/login.c, login/logout.c, login/logwtmp.c: Complete rewrite. Now based on getut*/setut* functions. * stdlib/strtol.c: Undo changes of Wed May 22 01:48:54 1996. This prevented using this file in other GNU packages. * sysdeps/gnu/utmpbits.h: Define _HAVE_UT_TYPE, _HAVE_UT_ID, and _HAVE_UT_TV because struct utmp has these members. * sysdeps/libm-i387/e_exp.S: Correct exp(+-Inf) case. * utmp.h: New file. Wrapper around login/utmp.h. * elf/dl-error.c (struct catch): New type. (catch): New static variable, struct catch *. (catch_env, signalled_errstring, signalled_objname): Variables removed. (_dl_signal_error): If CATCH is non-null, set its errstring and objname members and jump to CATCH->env. If it is null, call _dl_sysdep_fatal with a standard message. * elf/rtld.c (dl_main): Explode `doit' function into dl_main's body. No longer use _dl_catch_error. --- PROJECTS | 98 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 98 insertions(+) create mode 100644 PROJECTS (limited to 'PROJECTS') diff --git a/PROJECTS b/PROJECTS new file mode 100644 index 0000000000..3150ce11cf --- /dev/null +++ b/PROJECTS @@ -0,0 +1,98 @@ +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 + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +[ 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 already exists. + + Implementation idea: use some functions from bash. + + +[ 5] Write reentrent versions of crypt() et.al. + + Implementation idea: Define in + + 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.

Currently mostly i?86 optimized versions exist. + + +[ 8] Write nftw() function.
