2024-02-21Cygwin: strptime: fix am/pm handlingCorinna Vinschen1-3/+9
The %p format specifier is handled immediately. It requires that tm_hour is already set. This falls flat in case the am/pm marker preceeds the time specification. Locales with am/pm marker preceeding time spec by default exist (e. g. ko_KR). Also, the code expects that tm_hour might be set to an invalid value because the %p specifier is used in conjunction with %H. But this usage is invalid in itself and now catched as error condition after commit 343a2a558153 ("Cygwin: strptime: make sure to fail on invalid input digits"). Change the %H/%I/%p handling according to GLibC, i. e. - fix tm_hour for pm only if the time value has been specified as 12 hour time %I, and - perform the fixup only after the entire input has been scanned. This decouples the fixup from the %p position relativ to %I. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2024-02-21Cygwin: strptime: make sure to fail on invalid input digitsCorinna Vinschen1-3/+12
conv_num returns NULL if the input is invalid, e. g., the numbers are out of range. However, the code fails to test this in a lot of places. Rather than adding checks all over the place, rename conv_num to __conv_num and create a wrapper macro conv_num to perform the task of error checking.

2023-07-27Cygwin: fnmatch: fix range comparison in C localeCorinna Vinschen1-1/+1
Commit c36064bbd0c5 introduced operating on character pointers instead of operating on characters, to allow collating symbols. This patch neglected to change the expression for range comparison in case we're in the C locale. Thus it suddenly compared pointers instead of characters. Fix that.

2023-03-01Cygwin: fnmatch: support collating symbols in [. .] bracketsCorinna Vinschen1-130/+158
This requires quite a few changes in how fnmatch operates. It always operates on wint_t strings now, just like regex and glob, and it always keeps a pointer on the character inside the string, rather than operating on a single character. As a result, just drop the ifdef's for Cygwin. The code is non-portable now anyway... Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2023-02-28Cygwin: fnmatch: drop static variableCorinna Vinschen1-11/+2
fnmatch calls fnmatch1 with a static mbstate_t. This breaks calling fnmatch from multiple threads. Fix it by folding fnmatch1 into fnmatch and moving all mbstates to local variables. 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 Vinschen1-8/+4
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>

2020-08-05Cygwin: Add 'fallthrough' pseudo keyword for switch/case useCorinna Vinschen7-8/+9
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.

2016-08-20Only define __getreent inline function when building newlib or CygwinCorinna Vinschen1-0/+1
Commit 6f3943b erroneously removed the `#ifdef _COMPILING_NEWLIB' guarding the __getreent inline function. This patch ignored the fact that config.h is included when building applications, and the code in question requires internal, auto-generated headers to be available which are not exposed to user-space. Reinstantiate defined(_COMPILING_NEWLIB) test and alternatively check for defined (__INSIDE_CYGWIN__), otherwise we'd have to reinstantiate the __getreent macro in cygtls.h which is really confusing. While testing it turned out that a low number of source codes inside Cygwin won't see the inline __getreent due to a missing __INSIDE_CYGWIN__ definition. For malloc.cc this was actually deliberate to get different definitions from including cygmalloc.h. Change this by defining __INSIDE_CYGWIN__ in malloc.cc but changing the test in cygmalloc.h to test for defined(DLMALLOC_VERSION). This might need a change if we ever get around to replace dlmalloc with a newer, more threading-aware malloc implementation. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
