Steps to reproduce:
1. Start "LC_NUMERIC=de_DE.UTF-8 emacs-gtk -Q"
2. Type "0.25" in *scratch* buffer, then "C-j"
The input evaluates to "0.0" rather than "0.25".
The input is correctly interpreted when setting LC_NUMERIC=C.
This happens for both the EMacs 23.3 delivered with openSUSE 12.2 and
several self-compiled Emacsen, compiled both before the update to 12.2
and after the update to 12.2. The update involved quite a lot of system
libraries, but I think this error relates to the update of glib from
2.14 to 2.15 somehow.
In GNU Emacs 24.2.1 (i686-suse-linux-gnu, GTK+ Version 2.24.10)

Correction: I meant glibc in the above sentence.

I've just finished a Gtk-3 build: same issue, so Gtk version itself
doesn't seem to be a factor.

I suspect glibc have changed, because Emacs does
setlocale (LC_NUMERIC, "C");
when it starts up, so your setting should not matter.
I suggest you try to file a bugreport to OpenSuse.

Yes, that's what I suspect, too.

I already did, but I decided to send the opsnSUSE bug report first, so I
could add the upstream bug number there. I have meanwhile posted the
number here as well.

This particular problem looks like it's probably an OpenSUSE bug, but
in general one cannot combine LC_NUMERIC=C with random encodings in
LC_CTYPE. It's safer if Emacs uses the C locale when parsing floating
point numbers. Here's a proposed patch to do that. Can you apply
this against the Emacs trunk and give it a try?

Todays' trunk builds and I can apply your patch (sans the ChangeLog),
but the buggy behaviour doesn't change. Is there a way to check if the
patch has been applied correctly? Otherwise I'd say that your assertion
that there's a bug in openSUSE is correct, but I still don't understand
why and how it ignores an explicit locale setting…
Regards,
Achim.

No, it's an Emacs bug, actually two of them:
1. Emacs changes the locale _after_ GTK has been initialized, which,
according to the GTK docs, "may produce inconsistent results and is
not really supported" (see
http://developer.gnome.org/gtk/stable/gtk-General.html#gtk-set-locale).
2. To make the parsing (and printing?) of number literals in Emacs
Lisp locale-dependent is the wrong approach.
What is happening here is that, after Emacs's second call to
fixup_locale() (after initializing GTK), a module implicitly loaded by
GTK (GStreamer in this case, accessed by GTK via libcanberra) calls
setlocale(LC_ALL, "") again. The GTK docs explicitly say that such
things may happen.
Note that inserting gtk_disable_setlocale() before gtk_init() does not
help because this setting does not transcend to the loaded module.
A quick work-around is to start Emacs with LC_NUMERIC set to "C".
The long-term solution would be to fix Emacs's Lisp parser so that it
does not depend on the current locale. Hard-setting the locale to "C"
is bad style because it ignores the user's interface preferences.

I have not yet had a chance to test these patches. But is it really the
correct approach to set the locale to "C" whenever a number literal is read or
written and to set it back afterward? (Btw., is setlocale() thread-safe?)
Wouldn't it be simpler and more reliable to have number conversion functions
that are independent of the current locale?

Maybe I'm missing something, but declaring a variable volatile does not
automatically make it thread-safe, does it?

No, this docstring talks about gtk_set_locale, which emacs doesn't want
or need to change.

There are a lot of things that are wrong with internationalization, but
this isn't one of them IMHO. Emacs does call setlocale for it.

Please cite chapter and verse: if it's documented, then there should be
a documented way of dealing with it. Otherwise a _library_ changing the
locale out from under a program is a bug, especially when it is already
guaranteed that the library comes into existence in a sane locale
environment. I'd think that the gstreamer part is what has changed
between openSUSE 12.1 and 12.2, BTW.

That dangling carrot looks appealing, but it appears we'd really want to
gtk be initialized with the users' locale and not with the emacs altered
one.

This is done all the time in other applications. What's the point of
internationalization if you'd then need another function for each locale
and variant that the program intends to use? That is exactly why
setlocale returns an object that you can use to restore the locale at
any point in time.

Achim.

May I cite: "Note, however, that changing the locale after GTK+ is initialized
may produce inconsistent results and is not really supported." This warning
is not related to this particular function, as gtk_set_locale() does nothing
more than calling setlocale(LC_ALL, ""). Emacs calls this function via
gtk_init().

I don't know which are the things that are wrong with internationalization you
are referring to, but, IMHO, setting the locale or parts of it to a value
different from what the user has specified is the wrong approach. Lisp
programs are simply not localizable text.

To me, the warning cited above sounds sufficiently explicit.
Note that _any_ program having a localized user interface has to call
setlocale(LC_ALL, "") at the start to set the locale to the value specified by
its environment. gtk_init() simply does this for you. If you don't like that
behavior, you can initialize GTK without calling gtk_init() (but this wouldn't
help with GStreamer).
As to whether calling setlocale(LC_ALL, "") in a library is a bug, what would
you expect a library that wants to provide localized messages to do? Changing
the locale before and after each call? This would be racy in a multi-threaded
program.

I know that many programs do it that way, but this does not make it the
correct approach. Programs that reset (parts of) the locale to "C" have been
developed under the idea that the program "owns" the locale and can manipulate
it at will. In my -- extremely humble -- opinion, that is a misconception of
the locale concept. Locales provide a way for *users* to specify their
preferences wrt. localization. Therefore, the current locale belongs to the
*user*, and a localized program should not manipulate it beyond calling
setlocale(LC_ALL, ""), which is basically just an alias for "yes, I want to be
localized".
Now, what can programs do that have to manipulate text in multiple locales?
If you have complete control over everything, you can indeed switch the
current locale before and after each call to an input, output, conversion, or
string manipulation function. If you have multiple threads, don't forget to
properly synchronize these calls. The problem is that this is inefficient and
that you _don't have_ complete control in a program that interacts with many
components, like Emacs does. Do you want to race with GTK, GStreamer, or
whatever library over the current locale?
The better approach would be to have input, output, conversion, and string
manipulation functions that take a locale as an additional argument, similarly
to the C++ standard lib, where each stream has an assigned locale. Since the
code is already there, it would be an easy task to add such functions to glibc
(but this is probably not going to happen).
But for Emacs and most other programs, this isn't even needed. Most programs
manipulate only two kinds of text: user interface text, which should be
processed in the locale specified by the environment, and formal language
text, such as configuration files or program code, which should be processed
independently from the locale.
So, the only thing that has to be done for Emacs is to make all functions that
print or parse Lisp objects locale-independent (yes, this means you can't use
atof() for converting a number). This isn't too hard.
The other option would be to simply ignore localization and start Emacs always
with LANG=C.

There is a good reason why the C standard says "The implementation shall
behave as if no library function calls the setlocale function."
Extending that to other libraries improves the quality of
implementation.

Well, I didn't consider calling setlocale() in GStreamer a great idea, but you
and Achim are right: doing so is a bug because it's racy.
Nevertheless, setting LC_NUMERIC to "C" behind GTK's back isn't correct
either.
But in which places is Emacs using localized strings at all?

Are you saying that when I type in Emacs
M-: (* 2.0 2.0) RET
I'm supposed to use a comma instead of a period in a locale whose
LC_NUMERIC specifies a comma as the decimal separator?

Everything that comes from strftime, for example. You see that in
action in the tooltip shown when the mouse pointer is above the
mode-line time string, after turning on display-time.

That part is documented and it can be suppressed via
gtk_disable_setlocale() at the discretion of the application. The
warning about inconsistent results is about locale-dependent things set
up in gtk_init() that would need to be re-run if the locale changes.

Yes and that's a bug right there in GStreamer. If the locale
environment is already set up, it has no business in querying the
initial environment again.

An application may chose to never set up a locale and there should be a
way to tell libraries to respect that (I don't think there is a
foolproof way to check for whether a locale has already been set up by
the application). Gtk has that, but GStreamer is missing or ignoring
it. Plus it must be a development that happened in a version between
12.1 and 12.2. Here's another one with the same or very similar
problem:
https://github.com/pavouk/lgi/issues/19
I don't know where the "gstreamer override file" can be found that he
talks about. :-(

Achim.

You are entering Lisp code here. Would you agree that this qualifies as

Then what is "user interface text" you were talking about above? Does
user input qualify?

Gtk can not know if the program did this "behind its back" or if the user has

In some Gtk+ related places, such as the file dialog and other dialogs.

I admit that for a program like Emacs, this distinction is not always easy to
make because program code is part of its user interface. But I think that
most cases can be decided using common sense. Does the Emacs Lisp language
contain localized numbers? No, it does not. Hence, (* 0,25 1,3) is not a
valid Lisp expression, even undder a German locale. But when Emacs prints a
message like "Your disk is 23.4% full." in the local language, then I would
also expect the number 23.4 to be localized.
However, I have yet to see a localized message from Emacs.

BTW, does doing setlocale LC_NUMERIC before gtk_init make things work?

GTK sets the locale as specified in the corresponding environment variables.
If you modify these variables before GTK is initialized, it _will_ behave the
same.

Yes, and doing so is probably a good work-around for the short term.
But this doesn't solve the general problem: If Emacs is to be a localized
program, then it must not modify parts the locale on its own.

Ok, then setting LC_NUMERIC to "C" means that integer numbers displayed in
tooltips and other parts of the UI are not localized, while dates and other
strings are.

How can Emacs do both? How can it display "4.0" for the result of
'(* 2.0 2.0)', but "23,4%" in a message like "Your disk is 23.4% full."?
> However, I have yet to see a localized message from Emacs.
I think error messages that include text which comes from strerror are
another example, in addition to strftime I mentioned earlier.

What do you mean by "how"? Technically, philosophically, ...? How can GCC
print localized error messages, but still not accept 'double x = 0,25 * 1,0;'
in a C program?
I assume that most Emacs users can tell whether they are interacting with the
Lisp interpreter or the "other" user interface. So, what's the problem?

I don't think there is a place in Emacs where just a number is displayed.
Strings will be localized and they presumably have , in them if that is right
for the LC_MESSAGE locale.

If the number is hardcoded in the string that is. That is probably not the
common case though.

We are not talking about users, we are talking about Emacs, which is a
computer program. It needs to be able to differentiate between these
two instances of output, if you want it to use different decimal
separators in each case.

Should I have said: "How can GCC print localized error messages
containing (non-localized) C statements"? Are you seriously saying that
you see a hard technical problem here?

I assume that Emacs already has functions for printing and parsing Lisp
statements. Simply make them locale-independent. If you have to print
a localized string that contains a Lisp expression, insert the output of
the Lisp printer into that string. No Super-Turing powers required.

Hello.
I checked in the workaround. But it should be possible to find the places where LC_NUMERIC=C is needed and use locale independent routines there.

Not from within emacs, only if it is set as an environment variable.
The locale is reset again to the environment when gstreamer is
initialized, which is likely a bug in gstreamer. The main window is
already mapped at that time and the command loop is running.
The proper fix is likely to not bother with fixup_locale at all in its
current form, but either implement the lisp reader without
locale-dependent functions or getting a locale object on entry, change
the locale, do whatever it needs to do under changed locale and then
restore the locale. This is what libraries are often doing for parsing
configuration files, anyway.
There are also some hints that glib expects / recommends to call
setlocale, textdomain, bind_textdomain and bind_textdomain_codeset early
in main on order to properly initialize it.
Regards,
Achim.

Yes, that's what I meant. Sorry Jan, I didn't want to confuse you.
Calling fixup_locale() before gtk_init() won't help.

I am going to file a gstreamer bug for this. But since the
setlocale() call has been in gstreamer since 2004, it's probably not
going to change soon.

No, only the first approach will work. As it is currently
implemented, Emacs requires the numeric locale set to "C" whenever it
reads or writes lisp objects (which means: all the time), and changing
the locale before and after each such operation conflicts with
components that expect the "user" locale (such as GTK or GStreamer).
Besides, these components may start their own threads, which means
that setting the locale after these components have been initialized
introduces races.
If Emacs is to be a localized program, the Lisp parsers and writers
have to be made locale-independent; there is no way to avoid this.
fixup_locale() must go.

Yes, and the only call to setlocale() should be setlocale(LC_ALL, "")
very early, before the user interface is initialized (that's why
gtk_init() does exactly this).
