The unit test for mbrtowc uncovered four different bugs in various systems of
the system-provided mbrtowc function.
mbrtowc was introduced to allow traversing strings that are stored in
non-contiguous memory blocks. This essential functionality does not
work on AIX 5.1, HP-UX 11.11, OSF/1 5.1, Solaris 10.
I slowly get the feeling that all these operating systems are being
developed without any kind of testsuite.
The workarounds against all these bugs took me hours.
2008-12-20 Bruno Haible <br...@clisp.org>
Work around mbrtowc bugs on AIX, HP-UX, OSF/1, Solaris.
* lib/wchar.in.h (mbstate_t): Redefine also if REPLACE_MBSTATE_T is
set.
(GNULIB_defined_mbstate_t): New macro.
(mbsinit): Redefine if REPLACE_MBSINIT is set.
(mbrtowc): Redefine if REPLACE_MBRTOWC is set.
* lib/mbrtowc.c (rpl_mbrtowc): Add an alternative implementation that
reuses the system's mbrtowc function but works around the bugs.
* m4/mbrtowc.m4 (gl_MBSTATE_T_BROKEN, gl_MBRTOWC_INCOMPLETE_STATE,
gl_MBRTOWC_NULL_ARG, gl_MBRTOWC_RETVAL, gl_MBRTOWC_NUL_RETVAL): New
macros.
(gl_FUNC_MBRTOWC): Invoke them. Set REPLACE_MBRTOWC if mbrtowc needs to
be overridden. Optionally define MBRTOWC_NULL_ARG_BUG,
MBRTOWC_RETVAL_BUG, MBRTOWC_NUL_RETVAL_BUG.
* m4/mbsinit.m4 (gl_FUNC_MBSINIT): Invoke gl_MBSTATE_T_BROKEN. Set
REPLACE_MBSINIT if mbsinit needs to be overridden.
* m4/wchar.m4 (gl_WCHAR_H_DEFAULTS): Initialize REPLACE_MBSTATE_T,
REPLACE_MBSINIT, REPLACE_MBRTOWC.
* modules/wchar (Makefile.am): Substitute REPLACE_MBSTATE_T,
REPLACE_MBSINIT, REPLACE_MBRTOWC.
* modules/mbrtowc (Files): Add m4/locale-fr.m4, m4/locale-ja.m4,
m4/locale-zh.m4.
(Depends): Add mbsinit.
* modules/mbsinit (Depends): Add mbrtowc.
* doc/posix-functions/mbrtowc.texi: Mention the various bugs.
