2009-12-17check if USE_TLS is defined before useHans-Christian Egtvedt
This patch will convert all the #ifdef USE_TLS and #if USE_TLS to #if defined(USE_TLS) && USE_TLS. By checking if the USE_TLS is defined before checking its value will result in correct behavior for architectures not defining this config symbol.

2009-12-13syslog: fix openlog(xx, LOG_KERN) and optimize a bitDenys Vlasenko
The fix: logfac == 0 in openlog(xx, logfac) is allowed now. Corresponding internal openlog() call in vsyslog() uses explicit LOG_USER in order to set it as a default facility. Optimizations: mylock is not recursive now, since a single intenal call of openlog is converted to a call to openlog_internal which assumes that lock is already taken. No recursive locking is possible now. LogFacility is reduced to byte. cache static LogFile in auto variable fd (smaller code). vsyslog with bogus pri parameter wouldn't lock/unlock and mess with signals - it will just return at once. pass NULL as ident string in internal openlog call - same effect as passing LogTag but smaller code. comment out "if (LogTag)" checks - it is never NULL. use the same struct sigaction for setting new sigaction and for saving old one - saves ~32 bytes of stack.

2009-09-05utent.c: fix a few bugs, and shrink a bitDenys Vlasenko
bug #1: static_fd = -1; close(static_fd); DOH! bug #2: if (utmp_fd == -1) { __setutent(); } if (utmp_fd == -1) { return NULL; } if utmp_fd == -1, we call _setutent(). if __setutent() opens a fd, utmp_fd (a parameter) wouldn't change, the second check is bogus. We need to use static_fd instead in second check. Which makes clear that having utmp_fd parameter is wrong. See the patch for a complete fix. Shrink comes from simplifying fcntl(static_fd, F_SETFD, FD_CLOEXEC): text data bss dec hex filename - 661 8 384 1053 41d libc/misc/utmp/utent.o + 604 8 384 996 3e4 libc/misc/utmp/utent.o Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2009-07-20dirent: push dirent type to prototypesMike Frysinger
This syncs the dirent related functions with the glibc behavior -- rather than take void pointers everywhere, make the struct dirent pointers explicit in the API. After all, the functions themselves will cast the pointers to a dirent structure, so if it isn't as expected, people will crash. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-01-21*: remove __UCLIBC_CURLOCALE_DATA, __UCLIBC_CURLOCALE_DATA.xDenis Vlasenko
is always equivalent to __UCLIBC_CURLOCALE->x. remove typedef __uclibc_locale_t, it used only in a few places, it is lees confusing to use struct __uclibc_locale_struct everywhere. xlocale.h: hide __global_locale back under _LIBC, bug 53 is wrong in claiming it should be exported. Also hide under _LIBC: extern __locale_t __curlocale_var; extern __locale_t __curlocale(void); extern __locale_t __curlocale_set(__locale_t newloc); # define __UCLIBC_CURLOCALE # define __XL_NPP(N) # define __LOCALE_PARAM # define __LOCALE_ARG # define __LOCALE_PTR
