571eea83bb libc: Eliminate some relative relocations in setlocale(). 2011-12-27 23:28:01 +00:00
David Chisnall
3c87aa1d3d Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a
load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter.  Also
adds support for per-thread locales.  This work was funded by the FreeBSD
Foundation.

Please test any code you have that uses the C standard locale functions!

76692b8025 Rewrite locale loading procedures, so any load failure will not affect
currently cached data.  It allows a number of nice things, like: removing
fallback code from single locale loading, remove memory leak when LC_CTYPE
data loaded again and again, efficient cache use, not only for
setlocale(locale1); setlocale(locale1), but for setlocale(locale1);
setlocale("C"); setlocale(locale1) too (i.e.  data file loaded only once).

a17eafe2a8 1) Use errno to indicate faulure reason.
2) Move incomplete check for / in locale name from env section to
loadlocale(), add check for "." and ".." too.
It allows to check any argument, not env only.
3) Redesing LOAD_CATEGORY macro to eliminate code duplication.
4) Try harder in fallback code: if old locale can't be restored,
load "C" locale
5) White space formatting, long lines, etc.

825d095dd3 Fix setlocale() to conform to the ISO C and POSIX standards.
The below text is quoted from the latest POSIX draft:

: The values of locale categories shall be determined by a precedence
: order; the first condition met below determines the value:
:
: 1. If the LC_ALL environment variable is defined and is not null,
:    the value of LC_ALL shall be used.
: 2. If the LC_* environment variable (LC_COLLATE, LC_CTYPE, LC_MESSAGES,
:    LC_MONETARY, LC_NUMERIC, LC_TIME) is defined and is not null, the
:    value of the environment variable shall be used to initialize the
:    category that corresponds to the environment variable.
: 3. If the LANG environment variable is defined and is not null, the
:    value of the LANG environment variable shall be used.
: 4. If the LANG environment variable is not set or is set to the empty
:    string, the implementation-defined default locale shall be used.

The conditions 1 and 2 were interchanged, i.e., LC_* were looked first,
then LC_ALL, then LANG (note that LC_ALL and LANG were essentially the
same, providing the default, with LC_ALL taking precedence over LANG).
Now, LC_ALL and LANG serve the different purposes.  LC_ALL overrides
any LC_*, and LANG provides the default fallback.

Testcase:

/usr/bin/env LC_ALL=C LC_TIME=de_DE.ISO_8859-1 /bin/date

Should return date in the "C" locale format.

b777873ec1 Disallow '/' characters in LC_* environment variables which might
be used to point to a bad locale file. This is only believed to be a
minor security risk - the only risk is if some program uses the result
of a localized string as a format specifier in a vulnerable function
like sprintf(). No such code is believed to exist in the FreeBSD base
system, although it is possible that badly written third party code
would do that.

c8f931a80e PATH_LOCALE: use this non-standard env variable first time only, i.e.
strdup() it to prevent unsetenv() or setenv() effects. Check its length to
not allow user to overflow internal locale buffer. Move PATH_LOCALE
handling code into one place.

POSIX: make better stub for LC_MONETARY & LC_NUMERIC, now it check
locale directory existance instead of refusing all non-C non-POSIX
locales. POSIX treats empty locale env variable as unset variable
while our old code treats it as "C" locale, fix it. Implement previous locale
restoring, if locale setting fails. Old code assumes success if some
of LC_ALL subset is successed even other fails, POSIX treats it as
failure with previous locale restoring, fix it.

c28fbb7baa Implement locale-sensitive strftime () from ADO (heavily modified
by me).  This probably loses for multibyte characters, but I have no
way of telling.  I'll let ache decide whether to add this support to
startup_setlocale.  Note that for this to make any sense at all, the
symlinks in /usr/share/locale must go.  (For the moment, this doesn't
make any difference since there are no locales supplied.)
