2011-05-07	overhaul implementation-internal signal protections	Rich Felker	1	-18/+2
	the new approach relies on the fact that the only ways to create sigset_t objects without invoking UB are to use the sigset() functions, or from the masks returned by sigprocmask, sigaction, etc. or in the ucontext_t argument to a signal handler. thus, as long as sigfillset and sigaddset avoid adding the "protected" signals, there is no way the application will ever obtain a sigset_t including these bits, and thus no need to add the overhead of checking/clearing them when sigprocmask or sigaction is called. note that the old code actually failed* to remove the bits from sa_mask when sigaction was called. the new implementations are also significantly smaller, simpler, and faster due to ignoring the useless "GNU HURD signals" 65-1024, which are not used and, if there's any sanity in the world, never will be used.
2011-04-14	use a separate signal from SIGCANCEL for SIGEV_THREAD timers	Rich Felker	1	-0/+1
	otherwise we cannot support an application's desire to use asynchronous cancellation within the callback function. this change also slightly debloats pthread_create.c.
2011-03-20	global cleanup to use the new syscall interface	Rich Felker	1	-1/+1

2011-03-09	fix error handling for pthread_sigmask	Rich Felker	1	-1/+5
	it must return errno, not -1, and should reject invalud values for how.
2011-02-20	fix null pointer dereference introduced in last sigprocmask commit	Rich Felker	1	-1/+1

2011-02-19	prevent sigprocmask/pthread_sigmask from blocking implementation signals	Rich Felker	1	-3/+5
	this code was wrongly disabled because the old version was trying to be too clever and didn't work. replaced it with a simple version for now.
2011-02-12	initial check-in, version 0.5.0v0.5.0	Rich Felker	1	-0/+23
