Make it global, with attribute_hidden. * locale/localeinfo.h: Declare it. * locale/Makefile (aux): Add localename. * locale/localename.c (__current_locale_name): New function. * include/locale.h (__current_locale_name): Declare it. * intl/dcigettext.c (guess_category_value): Use that instead of calling setlocale. * locale/locale.h [__USE_GNU] (locale_t): New type alias of __locale_t. [__USE_GNU] (newlocale, duplocale, freelocale, uselocale): New decls. [__USE_GNU] (LC_GLOBAL_LOCALE): New macro. * locale/newlocale.c: Add alias to __ name. * locale/duplocale.c: Likewise. * locale/freelocale.c: Likewise. * locale/uselocale.c: New file. * locale/Makefile (routines): Add it. * locale/Versions (libc: GLIBC_2.3): New set. Add newlocale, duplocale, freelocale, uselocale. (libc: GLIBC_PRIVATE): Add __uselocale. * locale/localeinfo.h [SHARED] (_NL_CURRENT_LOCALE): New macro, defined to fetch a tsd value. (_NL_CURRENT_DATA): Define using that. (_NL_CURRENT, _NL_CURRENT_WSTR, _NL_CURRENT_WORD): Define using that. (_NL_CURRENT_DEFINE): Define to empty. [! SHARED]: Decls of _nl_current_CATEGORY and _nl_current conditionalized on this. * locale/xlocale.c (NL_C_INTIIALIZER): New macro, taking initializer of _nl_C_locobj. [SHARED] (_nl_global_locale): New variable, using that initializer. (_nl_C_locobj): Use new macro for initialzier. * locale/setlocale.c [! SHARED] (_nl_current): Conditionalize on this. [! SHARED] (CATEGORY_USED): New macro. [SHARED] (CATEGORY_USED, _nl_C): New macros. (setdata, setlocale): Use that macro instead of examining _nl_current. (setdata): Set the slot in _nl_global_locale. Conditionalize setting of _nl_current on [! SHARED]. * locale/findlocale.c [SHARED] (_nl_C): Define as a macro instead of declaration as an extern. * locale/newlocale.c (__newlocale): Use _nl_C_locobj instead of _nl_C. * include/locale.h: Use libc_hidden_proto for setlocale. * locale/setlocale.c: Add libc_hidden_def. * locale/setlocale.c (free_mem): Use _NL_CURRENT_DATA. --- locale/setlocale.c | 46 ++++++++++++++++++++++++++++------------------ 1 file changed, 28 insertions(+), 18 deletions(-) (limited to 'locale/setlocale.c') diff --git a/locale/setlocale.c b/locale/setlocale.c index 87573024d3..50963d152c 100644 --- a/locale/setlocale.c +++ b/locale/setlocale.c @@ -27,6 +27,8 @@ #include "localeinfo.h" +#ifndef SHARED + /* For each category declare two external variables (with weak references): extern const struct locale_data *_nl_current_CATEGORY; This points to the current locale's in-core data for CATEGORY. @@ -35,6 +37,8 @@ Both are weak references; if &_nl_current_CATEGORY is zero, then nothing is using the locale data. */ #define DEFINE_CATEGORY(category, category_name, items, a) \ +weak_extern (_nl_current_##category) \ +weak_extern (_nl_C_##category) \ extern struct locale_data *_nl_current_##category; \ extern struct locale_data _nl_C_##category; #include "categories.def" @@ -63,6 +67,19 @@ struct locale_data *const _nl_C[] attribute_hidden = #undef DEFINE_CATEGORY }; +# define CATEGORY_USED(category) (_nl_current[category] != NULL) + +#else + +/* The shared library always loads all the categories, + and the current global settings are kept in _nl_global_locale. */ + +# define _nl_C (_nl_C_locobj.__locales) + +# define CATEGORY_USED(category) (1) + +#endif + /* Define an array of category names (also the environment variable names), indexed by integral category. */ @@ -105,18 +122,6 @@ static void (*const _nl_category_postload[]) (void) = }; -/* Name of current locale for each individual category. - Each is malloc'd unless it is nl_C_name. */ -static const char *_nl_current_names[] = - { -#define DEFINE_CATEGORY(category, category_name, items, a) \ - [category] = _nl_C_name, -#include "categories.def" -#undef DEFINE_CATEGORY - [LC_ALL] = _nl_C_name /* For LC_ALL. */ - }; - - /* Lock for protecting global data. */ __libc_lock_define_initialized (, __libc_setlocale_lock attribute_hidden) @@ -200,20 +205,24 @@ setname (int category, const char *name) _nl_current_names[category] = name; } - /* Put DATA in *_nl_current[CATEGORY]. */ static inline void setdata (int category, struct locale_data *data) { - if (_nl_current[category] != NULL) + if (CATEGORY_USED (category)) { +#ifdef SHARED + _nl_global_locale.__locales[category] = data; +#endif +#ifndef SHARED +# warning when uselocale exists it will need the line above too *_nl_current[category] = data; +#endif if (_nl_category_postload[category]) (*_nl_category_postload[category]) (); } } - char * setlocale (int category, const char *locale) { @@ -371,7 +380,7 @@ setlocale (int category, const char *locale) /* Protect global data. */ __libc_lock_lock (__libc_setlocale_lock); - if (_nl_current[category] != NULL) + if (CATEGORY_USED (category)) { /* Only actually load the data if anything will use it. */ newdata = _nl_find_locale (locale_path, locale_path_len, category, @@ -409,7 +418,7 @@ setlocale (int category, const char *locale) } else { - if (_nl_current[category] != NULL) + if (CATEGORY_USED (category)) setdata (category, newdata); setname (category, newname[0]); @@ -429,6 +438,7 @@ setlocale (int category, const char *locale) return (char *) newname[0]; } } +libc_hidden_def (setlocale) static void __attribute__ ((unused)) free_mem (void) @@ -438,7 +448,7 @@ free_mem (void) for (category = 0; category < __LC_LAST; ++category) if (category != LC_ALL) { - struct locale_data *here = *_nl_current[category]; + struct locale_data *here = _NL_CURRENT_DATA (category); struct loaded_l10nfile *runp = _nl_locale_file_list[category]; /* If this category is already "C" don't do anything. */ -- cgit v1.2.3
