2023-03-20Cygwin: regex: fix faulty check for valid range expressionCorinna Vinschen1-3/+1
Except for the "C" or "POSIX" locale, checking for start <= finish is always wrong. Range start must be <= range finish in terms of the locale's collating order. So make sure to call always wcscoll(), even in the "C"/"POSIX" locale, which makes wcscoll equivalent to wcscmp anyway. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2023-03-20Cygwin: regex: fix freeing g->charjump in low memory conditionCorinna Vinschen1-1/+1
computejumps() moves g->charjump to a position relativ to the value of CHAR_MIN. As such, g->charjump doesn't necessarily point to the address actually allocated. While regfree() takes that into account, the low memory handling in regcomp_internal() doesn't. Fix that by free'ing the actually allocated address, as in regfree().

2023-03-16Cygwin: regex: NONCHAR: re-add cast to intCorinna Vinschen1-1/+1
wint_t is unsigned int and the test checks for a negative value. Thus, it's optimized out by gcc. Add the cast from commit 44caccfca2433 to avoid this. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2023-02-24Cygwin: convert Windows locale handling from LCID to ISO5646 stringsCorinna Vinschen1-1/+1
Since Windows Vista, locale handling is converted from using numeric locale identifiers (LCID) to using ISO5646 locale strings. In the meantime Windows introduced new locales which don't even have a LCID attached. Those were unusable in Cygwin because locale information for these locales required to call the new locale functions taking a locale string. Convert Cygwin to drop LCIDs and use Windows ISO5646 locales instead. The last place using LCIDs is the __set_charset_from_locale function. Checking numerically is easier and uslay faster than checking strings. However, this function is clearly a TODO
2023-02-19Cygwin: convert __collate_range_cmp to __wcollate_range_cmpCorinna Vinschen1-3/+3
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=179721 After FreeBSD eventually picked up the bugreport from within only 5 years, rename __collate_range_cmp to __wcollate_range_cmp as suggested all along, and make it type safe (wint_t instead of wchar_t for hopefully obvious reasons...) While at it, drop __collate_load_error and fix the checks for it in glob and fnmatch. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2023-02-14Cygwin: regex: convert wchar_t to wint_tCorinna Vinschen2-39/+8
- call mbrtowi instead of mbrtowc - drop Cygwin-only surrogate handling from wgetnext and xmbrtowc since it's encapsulated in mbrtowi. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2020-08-05Cygwin: Add 'fallthrough' pseudo keyword for switch/case useCorinna Vinschen1-3/+3
This patch has been inspired by the Linux kernel patch 294f69e662d1 compiler_attributes.h: Add 'fallthrough' pseudo keyword for switch/case use written by Joe Perches <joe AT perches DOT com> based on an idea from Dan Carpenter <dan DOT carpenter AT oracle DOT com>. The following text is from the original log message: Reserve the pseudo keyword 'fallthrough' for the ability to convert the various case block /* fallthrough */ style comments to appear to be an actual reserved word with the same gcc case block missing fallthrough warning capability. All switch/case blocks now should end in one of: break; fallthrough; goto <label>; return [expression]; continue; In C mode, GCC supports the __fallthrough__ attribute since 7.1, the same time the warning and the comment parsing were introduced. Cygwin-only: add an explicit -Wimplicit-fallthrough=5 to the build flags.

2016-08-20Introduce __current_locale_charset/__locale_charsetCorinna Vinschen1-2/+2
The former __locale_charset always fetched the current locale's charset. We need the per-locale charset, too, in future. Rename __locale_charset to __current_locale_charset and change __locale_charset to take a locale_t as parameter. Accommodate througout. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2016-08-15POSIX-1.2008 per-thread locales, groundwork part 2Corinna Vinschen1-6/+2
Move all locale category structure definitions into setlocale.h and remove other headers in locale subdir. Create inline accessor functions for current category struct pointers and use throughout. Use pointers to "C" locale category structs by default in __global_locale. Signed-off by: Corinna Vinschen <corinna@vinschen.de>
2016-08-15POSIX-1.2008 per-thread locales, groundwork part 1Corinna Vinschen1-4/+3
Introduce first cut of struct _thr_locale_t used for the locale_t definition. Introduce global instance called __global_locale used by default. Introduce internal inline functions __get_global_locale, __get_locale_r, __get_current_locale. Remove usage of global variables in favor of accessor functions pointing to __global_locale for now. Include all local headers in locale subdir from setlocale.h to get single include for internal locale access. Introduce __CTYPE_PTR macro to replace direct access to __ctype_ptr__ and use throughout in isxxx functions. Signed-off by: Corinna Vinschen <corinna@vinschen.de>
