* Avoid excessive locking and calling tzset in time functions.Corinna Vinschen2015-04-231-1/+1
| | | | | | | | | | * libc/time/lcltime_r.c (localtime_r): Call _tzset_unlocked inside TZ lock. * libc/time/mktime.c (mktime): Ditto. * libc/time/strftime.c (strftime, wcsftime): Ditto. Guard against calling _tzset_unlocked more than once (baring recursion). Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Move tzset calls to time functions.Craig Howland2015-04-231-0/+1
| | | | | | | | | | * libc/stdlib/setenv_r.c (_setenv_r): Remove tzset() call for TZ definition. * libc/time/lcltime_r.c (localtime_r): Add tzset() call * libc/time/mktime.c (mktime): Ditto. * libc/time/strftime.c (strftime, wcsftime): Ditto. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

| | | | | | | | | | | | | | | | | | * libc/time/month_lengths.c: New file with __month_lengths array (previously mon_lengths array in mktm_r.c) * libc/time/tzcalc_limits.c: New file with __tzcalc_limits() from mktm_r.c * libc/time/lcltime_r.c (localtime_r): Simplify by changing call to _mktm_r() with call to gmtime_r() and code moved from _mktm_r() which was used to do time zone adjustments * libc/time/gmtime_r.c (gmtime_r): Simplify by moving all relevant code from _mktm_r(), breaking all dependencies on time zone related functions * libc/time/mktm_r.c: Delete file * libc/time/local.h: Update accordingly - remove declaration of _mktm_r(), add declaration of __month_lengths[] * libc/time/Makefile.am: Modify accordingly. * libc/time/Makefile.in: Regenerate.

| | | | | | | | | | | | * libc/include/time.h (time): Add restrict keyword. * libc/include/wchar.h (wcsftime): Add restrict keyword. * libc/time/asctime_r.c (asctime_r): Same. * libc/time/gmtime_r.c (gmtime_r): Same. * libc/time/lcltime_r.c (lcltime_r): Same. * libc/time/strftime.c (strftime): Same. * libc/time/strptime.c (strptime): Same. * libc/sys/linux/linuxthreads/timer_create.c (timer_create): Same. * libc/sys/linux/linuxthreads/timer_settime.c (timer_settime): Same.

| | | | | | | | | | | | | | | | | | | | | | | | | | | * libc/include/time.h (tzset, _tzset_r): Added prototypes. (strptime): Moved prototype to be within !__STRICT_ANSI__. (_tzname, _daylight, _timezone): No long __CYGWIN__ only. (tzname): Defined for all platforms. (daylight, timezone): Defined only for CYGWIN. * libc/sys/linux/machine/i386/crt0.c: Add call to tzset() after environment set up. * libc/stdlib/setenv_r.c (_setenv_r): Call tzset() if the TZ environment variable is set. * libc/time/Makefile.am: Add support for tzset.c, tzlock.c, and tzset_r.c. * libc/time/Makefile.in: Regenerated. * libc/time/gmtime.c (gmtime): Changed to call gmtime_r. * libc/time/gmtime_r.c (gmtime_r): Changed to call _mktm_r. * libc/time/lcltime_r.c (lcltime_r): Ditto. * libc/time/local.h: New local header file. * libc/time/mktime.c (mktime): Add timezone support. * libc/time/mktm_r.c: New file which is the common engine for gmtime_r and lcltime_r. This code has timezone support. * libc/time/strftime.c (strftime): Add %Z timezone support. * libc/time/tzlock.c: New file containing timezone lock stubs. * libc/time/tzset.c: New file containing tzset() routine. * libc/time/tzset_r.c: New file containing _tzset_r and internal routine for calculating timezone changes for specified year.
