2012-12-06add sigandset and sigorset (needed for qemu)rofl0r-0/+3
2012-12-03feature test macros: make _GNU_SOURCE enable everythingRich Felker-1/+1
previously, a few BSD features were enabled only by _BSD_SOURCE, not by _GNU_SOURCE. since _BSD_SOURCE is default in the absence of other feature test macros, this made adding _GNU_SOURCE to a project not a purely additive feature test macro; it actually caused some features to be suppressed. most of the changes made by this patch actually bring musl in closer alignment with the glibc behavior for _GNU_SOURCE. the only exceptions are the added visibility of functions like strlcpy which were BSD-only due to being disliked/rejected by glibc maintainers. here, I feel the consistency of having _GNU_SOURCE mean "everything", and especially the property of it being purely additive, are more valuable than hiding functions which glibc does not have.
2012-11-30provide NSIG under _BSD_SOURCE (default) as well as _GNU_SOURCERich Felker-1/+4
this fixes a regression related to the changes made to bits/signal.h between 0.9.7 and 0.9.8 that broke some (non-portable) software.
2012-11-25fixup mcontext stuff to expost gregset_t/fpregset_t as appropriateRich Felker-0/+1
2012-11-21add back NSIG, removed from powerpc in last commit, but for all archsRich Felker-0/+1
unlike the previous definition, NSIG/_NSIG is supposed to be one more than the highest signal number. adding this will allow simplifying libc-internal code that makes signal-related syscalls, which can be done as a later step. some apps might use it too; while this usage is questionable, it's at least not insane.
2012-09-07default features: make musl usable without feature test macrosRich Felker-5/+1
the old behavior of exposing nothing except plain ISO C can be obtained by defining __STRICT_ANSI__ or using a compiler option (such as -std=c99) that predefines it. the new default featureset is POSIX with XSI plus _BSD_SOURCE. any explicit feature test macros will inhibit the default. installation docs have also been updated to reflect this change.
2012-09-06use restrict everywhere it's required by c99 and/or posix 2008Rich Felker-7/+13
to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.
2012-07-12fix redef of sigprocmask constants on mipsRich Felker-2/+0
this fix is easier than trying to reorder the header stuff
2012-07-12more mips bits-header fixesRich Felker-0/+2
signal handling was very broken because of this
2012-05-22bsd_signal is a legacy (removed) XSI function, not needed in _BSD_SOURCERich Felker-4/+1
its only purpose was for use on non-BSD systems that implement sysv semantics for signal() by default.
2012-05-22support _BSD_SOURCE feature test macroRich Felker-2/+10
patch by Isaac Dunham. matched closely (maybe not exact) to glibc's idea of what _BSD_SOURCE should make visible.
2012-04-13rename __sa_restorer to sa_restorer in struct sigactionRich Felker-1/+1
this is legal since sa_* is in the reserved namespace for signal.h, per posix. note that the sa_restorer field is not used anywhere, so programs that are trying to use it may still break, but at least they'll compile. if it turns out such programs actually need to be able to set their own sa_restorer to function properly, i'll add the necessary code to sigaction.c later.
2012-01-25fix typo in FPE_FLTUND definition, signal.hRich Felker-1/+1
2011-09-21fix missing SIG_DFL, SIG_IGN, SIG_ERR without posix in signal.hRich Felker-5/+6
2011-09-20fix broken siginfo_t with _GNU_SOURCE definedRich Felker-6/+5
this bug was introduced in a recent patch. the problem we're working around is that broken GNU software wants to use "struct siginfo" rather than "siginfo_t", but "siginfo" is not in the reserved namespace and thus not legal for the standard header to use.

2011-09-02fix missing prototypes/wrong signature for psiginfo, psignalRich Felker-0/+3
2011-06-16fix some struct padding to match LSB/glibc ABI where it may be helpfulRich Felker-0/+1
2011-05-05add SA_NOMASK alias for SA_NODEFER with _GNU_SOURCERich Felker-0/+1
2011-04-13fix incorrect GNU sighandler_t typedefRich Felker-1/+1
2011-03-29implement POSIX timersRich Felker-6/+16
this implementation is superior to the glibc/nptl implementation, in that it gives true realtime behavior. there is no risk of timer expiration events being lost due to failed thread creation or failed malloc, because the thread is created as time creation time, and reused until the timer is deleted.
2011-02-20move the GNU siginfo renaming so it doesn't lead to mismatching namesRich Felker-1/+4
