From b98192b80ee5654aa7c5590bcc266c5eec2c67a5 Mon Sep 17 00:00:00 2001 From: Eugene Yudin Date: Mon, 24 Jul 2017 22:27:00 +0200 Subject: fix tolower and locales The function towlower doesn't work with locales different from C. Issue was introduced in commit: 8cde3a9bf2856dcb9a759dec7ecb04a68e712254 Call to setlocale is needed for correct generation of the table uplow_diff. Otherwise you receive compile time error "range assumption error" after uncommenting the call. Similar problem described here: http://lists.uclibc.org/pipermail/uclibc/2015-March/048852.html This commit fix the problem by using int32_t values. --- extra/locale/gen_ldc.c | 16 +++++++++++++++- extra/locale/gen_wctype.c | 13 ++++++------- extra/locale/locale_mmap.h | 2 +- 3 files changed, 22 insertions(+), 9 deletions(-) (limited to 'extra') diff --git a/extra/locale/gen_ldc.c b/extra/locale/gen_ldc.c index 2cedbddaf..5f454026f 100644 --- a/extra/locale/gen_ldc.c +++ b/extra/locale/gen_ldc.c @@ -129,6 +129,20 @@ void out_i16(FILE *f, const int16_t *p, size_t n, char *comment) fprintf(f, "\n},\n"); } +void out_i32(FILE *f, const int32_t *p, size_t n, char *comment) +{ + size_t i; + + fprintf(f, "{\t/* %s */", comment); + for (i = 0 ; i < n ; i++) { + if (!(i & 7)) { + fprintf(f, "\n\t"); + } + fprintf(f, "%11d, ", p[i]); + } + fprintf(f, "\n},\n"); +} + void out_size_t(FILE *f, const size_t *p, size_t n, char *comment) { size_t i; @@ -194,7 +208,7 @@ int main(int argc, char **argv) #ifdef __WCHAR_ENABLED out_uc(lso, __LOCALE_DATA_WCctype_data, __LOCALE_DATA_WCctype_TBL_LEN, "tblwctype"); out_uc(lso, __LOCALE_DATA_WCuplow_data, __LOCALE_DATA_WCuplow_TBL_LEN, "tblwuplow"); - out_i16(lso, __LOCALE_DATA_WCuplow_diff_data, __LOCALE_DATA_WCuplow_diff_TBL_LEN, "tblwuplow_diff"); + out_i32(lso, __LOCALE_DATA_WCuplow_diff_data, __LOCALE_DATA_WCuplow_diff_TBL_LEN, "tblwuplow_diff"); /* const unsigned char tblwcomb[WCcomb_TBL_LEN]; */ /* width?? */ #endif /* __WCHAR_ENABLED */ diff --git a/extra/locale/gen_wctype.c b/extra/locale/gen_wctype.c index 70345096b..99c505d44 100644 --- a/extra/locale/gen_wctype.c +++ b/extra/locale/gen_wctype.c @@ -83,8 +83,8 @@ #define mywxdigit(D,C) (mywdigit(D,C) || (unsigned)(((C) | 0x20) - 'a') <= 5) typedef struct { - short l; - short u; + int32_t l; + int32_t u; } uldiff_entry; typedef struct { @@ -227,12 +227,11 @@ int main(int argc, char **argv) ++verbose; continue; } - /* setlocale might be just a stub */ - /* if (!setlocale(LC_CTYPE, *argv)) { + /* setlocale might be just a stub */ + if (!setlocale(LC_CTYPE, *argv)) { verbose_msg("setlocale(LC_CTYPE,%s) failed!
