Design of xlocale
=================
The xlocale APIs come from Darwin, although a subset is now part of POSIX 2008.
They fall into two broad categories:
- Manipulation of per-thread locales (POSIX)
- Locale-aware functions taking an explicit locale argument (Darwin)
This document describes the implementation of these APIs for FreeBSD.
Goals
-----
The overall goal of this implementation is to be compatible with the Darwin
version. Additionally, it should include minimal changes to the existing
locale code. A lot of the existing locale code originates with 4BSD or earlier
and has had over a decade of testing. Replacing this code, unless absolutely
necessary, gives us the potential for more bugs without much benefit.
With this in mind, various libc-private functions have been modified to take a
locale_t parameter. This causes a compiler error if they are accidentally
called without a locale. This approach was taken, rather than adding _l
variants of these functions, to make it harder for accidental uses of the
global-locale versions to slip in.
Locale Objects
--------------
A locale is encapsulated in a `locale_t`, which is an opaque type: a pointer to
a `struct _xlocale`. The name `_xlocale` is unfortunate, as it does not fit
well with existing conventions, but is used because this is the name the Darwin
implementation gives to this structure and so may be used by existing (bad) code.
This structure should include all of the information corresponding to a locale.
A locale_t is almost immutable after creation. There are no functions that modify it,
and it can therefore be used without locking. It is the responsibility of the
caller to ensure that a locale is not deallocated during a call that uses it.
Each locale contains a number of components, one for each of the categories
supported by `setlocale()`. These are likewise immutable after creation. This
differs from the Darwin implementation, which includes a deprecated
`setinvalidrune()` function that can modify the rune locale.
The exception to these mutability rules is a set of `mbstate_t` flags stored
with each locale. These are used by various functions that previously had a
static local `mbstate_t` variable.
The components are reference counted, and so can be aliased between locale
objects. This makes copying locales very cheap.
The Global Locale
-----------------
All locales and locale components are reference counted. The global locale,
however, is special. It, and all of its components, are static and so no
malloc() memory is required when using a single locale.
This means that threads using the global locale are subject to the same
constraints as with the pre-xlocale libc. Calls to any locale-aware functions
in threads using the global locale, while modifying the global locale, have
undefined behaviour.
Because of this, we have to ensure that we always copy the components of the
global locale, rather than alias them.
It would be cleaner to simply remove the special treatment of the global locale
and have a locale_t lazily allocated for the global context. This would cost a
little more `malloc()` memory, so is not done in the initial version.
Caching
-------
The existing locale implementation included several ad-hoc caching layers.
None of these were thread safe. Caching is only really of use for supporting
the pattern where the locale is briefly changed to something and then changed
back.
The current xlocale implementation removes the caching entirely. This pattern
is not one that should be encouraged. If you need to make some calls with a
modified locale, then you should use the _l suffix versions of the calls,
rather than switch the global locale. If you do need to temporarily switch the
locale and then switch it back, `uselocale()` provides a way of doing this very
easily: It returns the old locale, which can then be passed to a subsequent
call to `uselocale()` to restore it, without the need to load any locale data
from the disk.
If, in the future, it is determined that caching is beneficial, it can be added
quite easily in xlocale.c. Given, however, that any locale-aware call is going
to be a preparation for presenting data to the user, and so is invariably going
to be part of an I/O operation, this seems like a case of premature
optimisation.
localeconv
----------
The `localeconv()` function is an exception to the immutable-after-creation
rule. In the classic implementation, this function returns a pointer to some
global storage, which is initialised with the data from the current locale.
This is not possible in a multithreaded environment, with multiple locales.
Instead, each locale contains a `struct lconv` that is lazily initialised on
calls to `localeconv()`. This is not protected by any locking, however this is
still safe on any machine where word-sized stores are atomic: two concurrent
calls will write the same data into the structure.
Explicit Locale Calls
---------------------
A large number of functions have been modified to take an explicit `locale_t`
parameter. The old APIs are then reimplemented with a call to `__get_locale()`
to supply the `locale_t` parameter. This is in line with the Darwin public
APIs, but also simplifies the modifications to these functions. The
`__get_locale()` function is now the only way to access the current locale
within libc. All of the old globals have gone, so there is now a linker error
if any functions attempt to use them.
The ctype.h functions are a little different. These are not implemented in
terms of their locale-aware versions, for performance reasons. Each of these
is implemented as a short inline function.
Differences to Darwin APIs
--------------------------
`strtoq_l()` and `strtouq_l() `are not provided. These are extensions to
deprecated functions - we should not be encouraging people to use deprecated
interfaces.
Locale Placeholders
-------------------
The pointer values 0 and -1 have special meanings as `locale_t` values. Any
public function that accepts a `locale_t` parameter must use the `FIX_LOCALE()`
macro on it before using it. For efficiency, this can be emitted in functions
which *only* use their locale parameter as an argument to another public
function, as the callee will do the `FIX_LOCALE()` itself.
Potential Improvements
----------------------
Currently, the current rune set is accessed via a function call. This makes it
fairly expensive to use any of the ctype.h functions. We could improve this
quite a lot by storing the rune locale data in a __thread-qualified variable.
Several of the existing FreeBSD locale-aware functions appear to be wrong. For
example, most of the `strto*()` family should probably use `digittoint_l()`,
but instead they assume ASCII. These will break if using a character encoding
that does not put numbers and the letters A-F in the same location as ASCII.
Some functions, like `strcoll()` only work on single-byte encodings. No
attempt has been made to fix existing limitations in the libc functions other
than to add support for xlocale.
Intuitively, setting a thread-local locale should ensure that all locale-aware
functions can be used safely from that thread. In fact, this is not the case
in either this implementation or the Darwin one. You must call `duplocale()`
or `newlocale()` before calling `uselocale()`. This is a bit ugly, and it
would be better if libc ensure that every thread had its own locale object.

.Dt DUPLOCALE 3
.Os
.Sh NAME
.Nm duplocale
.Nd duplicate an locale
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.In xlocale.h
.Ft locale_t
.Fn duplocale "locale_t locale"
.Sh DESCRIPTION
Duplicates an existing
.Fa locale_t
returning a new
.Fa locale_t
that refers to the same locale values but has independent internal state.
Various functions, such as
.Xr mblen 3
require presistent state. These functions formerly used static variables and
calls to them from multiple threads had undefined behavior. They now use
fields in the
.Fa locale_t
associated with the current thread by
.Xr uselocale 3 .
These calls are therefore only thread safe on threads with a unique per-thread
locale.
.Pt
The locale returned by this call must be freed with
.Xr freelocale 3 .
.Sh BUGS
Ideally,
.Xr uselocale 3
should make a copy of the
.Fa locale_t
implicitly to ensure thread safety, and a copy of the global locale should be
installed lazily on each thread. The FreeBSD implementation does not do this,
for compatibility with Darwin.
.Sh SEE ALSO
.Xr freelocale 3 ,
.Xr localeconv 3 ,
.Xr newlocale 3 ,
.Xr querylocale 3 ,
.Xr uselocale 3 ,

.Dt newlocale 3
.Os
.Sh NAME
.Nm newlocale
.Nd Creates a new locale
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.In xlocale
.Ft
.Fn newlocale "int mask" "const char * locale" "locale_t base"
.Sh DESCRIPTION
Creates a new locale, inheriting some properties from an existing locale. The
.Fa mask
defines the components that the new locale will have set to the locale with the
name specified in the
.Fa locale
parameter. Any other components will be inherited from
.Fa base .
.Pt
The
.Fa mask
is either
.Fa LC_ALL_MASK,
indicating all possible locale components, or the logical OR of some
combination of the following:
.Bl -tag -width "LC_MESSAGES_MASK" -offset indent
.It LC_COLLATE_MASK
The locale for string collation routines. This controls alphabetic ordering in
.Xr strcoll 3
and
.Xr strxfrm 3 .
.It LC_CTYPE_MASK
The locale for the
.Xr ctype 3
and
.Xr multibyte 3
functions. This controls recognition of upper and lower case, alpha- betic or
non-alphabetic characters, and so on.
.It LC_MESSAGES_MASK
Set a locale for message catalogs, see
.Xr catopen 3
function.
.It LC_MONETARY_MASK
Set a locale for formatting monetary values; this affects
the
.Xr localeconv 3
function.
.It LC_NUMERIC_MASK
Set a locale for formatting numbers. This controls the for-
matting of decimal points in input and output of floating
point numbers in functions such as
.Xr printf 3
and
.Xr scanf 3 ,
as well as values returned by
.Xr localeconv 3 .
.It LC_TIME_MASK
Set a locale for formatting dates and times using the
.Xr strftime 3
function.
.El
This function uses the same rules for loading locale components as
.Xr setlocale 3 .
.Sh RETURN VALUES
Returns a new, valid,
.Fa locale_t
or NULL if an error occurs. You must free the returned locale with
.Xr freelocale 3 .
.Sh SEE ALSO
.Xr duplocale 3 ,
.Xr freelocale 3 ,
.Xr localeconv 3 ,
.Xr querylocale 3 ,
.Xr uselocale 3 ,
.Xr xlocale 3
.Sh STANDARDS
This function, conforms to
.St -p1003.1-2008

.Dt XLOCALE 3
.Os
.Sh NAME
.Nm xlocale
.Nd Thread-safe extended locale support.
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.In xlocale.h
.Sh DESCRIPTION
The extended locale support includes a set of functions for setting
thread-local locales, as well convenience functions for performing locale-aware
calls with a specified locale.
.Pp
The core of the xlocale API is the
.Fa locale_t
type. This is an opaque type encapsulating a locale. Instances of this can be
either set as the locale for a specific thread or passed directly to the
.Fa _l
suffixed variants of various standard C functions. Two special
.Fa locale_t
values are available:
.Bl -bullet -offset indent
.It
NULL refers to the current locale for the thread, or to the global locale if no
locale has been set for this thread.
.It
LC_GLOBAL_LOCALE refers to the global locale.
.El
.Pp
The global locale is the locale set with the
.Xr setlocale 3
function.
.Sh CAVEATS
The
.Xr setlocale 3
function, and others in the family, refer to the global locale. Other
functions that depend on the locale, however, will take the thread-local locale
if one has been set. This means that the idiom of setting the locale using
.Xr setlocale 3 ,
calling a locale-dependent function, and then restoring the locale will not
have the expected behavior if the current thread has had a locale set using
.Xr uselocale 3 .
You should avoid this idiom and prefer to use the
.Fa _l
suffixed versions instead.
.Sh SEE ALSO
.Xr duplocale 3 ,
.Xr freelocale 3 ,
.Xr localeconv 3 ,
.Xr newlocale 3 ,
.Xr querylocale 3 ,
.Xr uselocale 3 ,
.Sh CONVENIENCE FUNCTIONS
The xlocale API includes a number of
.Fa _l
suffixed convenience functions. These are variants of standard C functions
that have been modified to take an explicit
.Fa locale_t
parameter as the final argument or, in the case of variadic functions, as an
additional argument directly before the format string. Each of these functions
accepts either NULL or LC_GLOBAL_LOCALE. In these functions, NULL refers to
the C locale, rather than the thread's current locale. If you wish to use the
thread's current locale, then use the unsuffixed version of the function.
.Pp
These functions are exposed by including
.In xlocale.h
.Em after
including the relevant headers for the standard variant. For example, the
.Xr strtol_l 3
function is exposed by including
.In xlocale.h
after
.In stdlib.h ,
which defines
.Xr strtol 3 .
.Pp
For reference, a complete list of the locale-aware functions that are available
in this form, along with the headers that expose them, is provided here:
