[Bug libstdc++/13631] New: Problems in messages

[peturr02 at ru dot is]

The messages facet is broken.

1) The return values of the get member function depend on global state
as set by textdomain() (which is called from messages::do_open()). This
is forbidden by the resolution of DR 360.

2) messages<wchar_t> doesn't work at all (get() always returns the
empty string).

It looks like we can at least fix 1) rather easily by using dgettext in
do_get. About 2), _M_convert_from_char is currently completely broken :(...
Let's see what I can do!
Thanks!

I see... I'm not sure that this part can really be fixed in the implementation
relying on gettext, which purposedly adds the extension

  open(const basic_string<char>&, const locale&, const char*)

to specify the message catalog root directory.
Hum...

Ok, sorry, you mean bind_textdomain_codeset not bind_textdomain, I see...

Anyway, testcase 3.cc passes for me, any idea why?

Thanks, Paolo.

Maybe you don't have the message catalogs installed?
You can check if this is the case by looking at the return value of get().
If it returns dfault (the last argument), then the message catalog is
missing.

On my system (Fedora Core 1) they are stored in
/usr/share/locale/is/LC_MESSAGES and come from a package named
kde-i18n-Icelandic

Update: honestly, I can't see how the issue with bind_textdomain_codeset
can be fixed in the 'gettext' framework, probably a case of WONTFIX. Does this
imply that eventually the GNU implementation should be that based on 'catgets'??

Bind_textdomain can be easily avoided in do_open and _M_convert_from_char
implemented, I can work on that.

Note that this problem is solvable: In the worst case, libintl needs to
be bypassed and message needs to read the message catalogs directly.
Another solution would be to include libintl in libstdc++ and rename
all exported functions and global variables, so messages wouldn't share
any state with gettext. This would have the additional benefit that
only a single implementation (based on gettext) could be used on all
platforms.
