*	document changes for 0.7.1 v0.7.1	Rich Felker	2011-03-18	1	-0/+9
\|
*	implement [v]swprintf	Rich Felker	2011-03-18	4	-3/+63
\|
*	implement wprintf family of functions	Rich Felker	2011-03-17	4	-0/+387
\| \| \| \| \| \| \| \| \|	this implementation is extremely ugly and inefficient, but it avoids a good deal of code duplication and bloat. it may be cleaned up later to eliminate the remaining code duplication and some of the warts, but i don't really care about its performance. note that swprintf is not yet implemented.
*	fix broken wmemchr (unbounded search)	Rich Felker	2011-03-17	1	-1/+1
\|
*	implement robust mutexes	Rich Felker	2011-03-17	10	-10/+84
\| \| \| \| \| \|	some of this code should be cleaned up, e.g. using macros for some of the bit flags, masks, etc. nonetheless, the code is believed to be working and correct at this point.
*	avoid function call to pthread_self in mutex unlock	Rich Felker	2011-03-17	1	-1/+1
\| \| \| \| \| \|	if the mutex was previously locked, we can assume pthread_self was already called at the time of locking, and thus that the thread pointer is initialized.
*	reorder mutex struct fields to make room for pointers (upcoming robust mutexes)	Rich Felker	2011-03-17	1	-1/+3
\| \| \| \| \| \|	the layout has been chosen so that pointer slots 3 and 4 fit between the integer slots on 32-bit archs, and come after the integer slots on 64-bit archs.
*	unify lock and owner fields of mutex structure	Rich Felker	2011-03-17	4	-8/+6
\| \| \| \| \| \|	this change is necessary to free up one slot in the mutex structure so that we can use doubly-linked lists in the implementation of robust mutexes.
*	optimize contended normal mutex case; add int compare-and-swap atomic	Rich Felker	2011-03-17	3	-1/+15
\|
*	simplify logic, slightly optimize contended case for non-default mutex types	Rich Felker	2011-03-16	1	-4/+2
\|
*	correct error returns for error-checking mutexes	Rich Felker	2011-03-16	2	-2/+6
\|
*	cut out a syscall on thread creation in the case where guard size is 0	Rich Felker	2011-03-16	1	-1/+1
\|
*	don't expose EAGAIN, etc. from timed futex wait to caller	Rich Felker	2011-03-16	1	-1/+4
\|
*	optimize file locking: avoid cache-polluting writes to global storage	Rich Felker	2011-03-16	2	-3/+5
\|
*	partially-written draft of fmemopen, still in #if 0	Rich Felker	2011-03-14	1	-3/+48
\|
*	remove some old cruft from sys/types.h	Rich Felker	2011-03-14	1	-1/+0
\|
*	misplaced & in times() made it fail to work, and clobber the stack	Rich Felker	2011-03-12	1	-1/+1
\|
*	implement flockfile api, rework stdio locking	Rich Felker	2011-03-12	9	-15/+66
\|
*	pthread.h needs clockid_t	Rich Felker	2011-03-12	1	-0/+1
\| \| \| \| \|	actually it gets this from time.h if _POSIX_C_SOURCE or any other feature test macros are defined, but it breaks if they're not.
*	document some additional important changes v0.7.0	Rich Felker	2011-03-11	1	-1/+2
\|
*	update whatsnew file for release of 0.7.0	Rich Felker	2011-03-11	1	-2/+4
\|
*	match dimensions so we can use all slots without invoking OOB-array-access	Rich Felker	2011-03-11	2	-10/+10
\|
*	implement dummy pthread_attr_[gs]etschedparam functions	Rich Felker	2011-03-11	2	-0/+14
\| \| \| \| \| \| \| \|	for some reason these functions are not shaded by the PS/TPS option in POSIX, so presumably they are mandatory, even though the functionality they offer is optional. for now, provide them in case any programs depend on their existence, but disallow any priority except the default.
*	fix pthread_attr_* implementations to match corrected prototypes	Rich Felker	2011-03-11	4	-4/+4
\|
*	fix missing ENOTSUP error code	Rich Felker	2011-03-11	2	-0/+2
\|
*	missing const in some pthread_attr_* prototypes	Rich Felker	2011-03-11	1	-8/+8
\|
*	formatting whatsnew file	Rich Felker	2011-03-11	1	-0/+6
\|
*	list major changes in preparation for release	Rich Felker	2011-03-11	1	-0/+23
\|
*	fix failure behavior of sem_open when sem does not exist	Rich Felker	2011-03-10	1	-1/+5
\|
*	fix some semaphore wait semantics (race condition deadlock and error checking)	Rich Felker	2011-03-10	2	-1/+7
\|
*	fix sem_open and sem_close to obey posix semantics	Rich Felker	2011-03-10	4	-38/+86
\| \| \| \| \| \| \| \| \|	multiple opens of the same named semaphore must return the same pointer, and only the last close can unmap it. thus the ugly global state keeping track of mappings. the maximum number of distinct named semaphores that can be opened is limited sufficiently small that the linear searches take trivial time, especially compared to the syscall overhead of these functions.
*	optimize pthread termination in the non-detached case	Rich Felker	2011-03-10	2	-4/+16
\| \| \| \| \| \| \|	we can avoid blocking signals by simply using a flag to mark that the thread has exited and prevent it from getting counted in the rsyscall signal-pingpong. this restores the original pthread create/join throughput from before the sigprocmask call was added.
*	fix errors in sigqueue (potential information leak, wrong behavior)	Rich Felker	2011-03-10	1	-5/+7
\| \| \| \| \| \| \| \|	1. any padding in the siginfo struct was not necessarily zero-filled, so it might have contained private data off the caller's stack. 2. the uid and pid must be filled in from userspace. the previous rsyscall fix broke rsyscalls because the values were always incorrect.
*	security fix: check that cancel/rsyscall signal was sent by the process itself	Rich Felker	2011-03-10	1	-0/+3
\|
*	more cancellation points: tcdrain, clock_nanosleep	Rich Felker	2011-03-10	2	-2/+12
\|
*	remove useless return value checks for functions that cannot fail	Rich Felker	2011-03-10	1	-3/+2
\|
*	make sigsuspend a cancellation point	Rich Felker	2011-03-10	1	-1/+6
\|
*	make sigtimedwait a cancellation point	Rich Felker	2011-03-10	1	-0/+3
\|
*	don't fail with EINTR in sigtimedwait	Rich Felker	2011-03-10	1	-6/+6
\| \| \| \| \|	POSIX allows either behavior, but sigwait is not allowed to fail with EINTR, so the retry loop would have to be in one or the other anyway.
*	fix sigsuspend syscall	Rich Felker	2011-03-10	1	-1/+1
\|
*	make sigaltstack work (missing macros in signal.h, error conditions)	Rich Felker	2011-03-10	3	-1/+15
\|
*	fix errno behavior in clock_* functions	Rich Felker	2011-03-10	3	-3/+0
\| \| \| \| \| \|	these functions are specified inconsistent in whether they're specified to return an error value, or return -1 and set errno. hopefully now they all match what POSIX requires.
*	fix error handling for pthread_sigmask	Rich Felker	2011-03-09	2	-1/+15
\| \| \| \|	it must return errno, not -1, and should reject invalud values for how.
*	make fork properly initialize the main thread in the child process	Rich Felker	2011-03-09	1	-0/+7
\|
*	optimize pthread initialization	Rich Felker	2011-03-09	1	-2/+2
\| \| \| \| \| \|	the set_tid_address returns the tid (which is also the pid when called from the initial thread) so there is no need to make a separate syscall to get pid/tid.
*	fix race condition in raise - just mask signals	Rich Felker	2011-03-09	1	-9/+9
\| \| \| \| \| \| \| \|	a signal handler could fork after the pid/tid were read, causing the wrong process to be signalled. i'm not sure if this is supposed to have UB or not, but raise is async-signal-safe, so it probably is allowed. the current solution is slightly expensive so this implementation is likely to be changed in the future.
*	fix raise semantics with threads.	Rich Felker	2011-03-09	1	-1/+12
\|
*	fix typos in dirent.h	Rich Felker	2011-03-08	1	-2/+2
\|
*	fcntl.h should make availabel the mode constants from sys/stat.h	Rich Felker	2011-03-08	2	-8/+20
\| \| \| \|	also remove some legacy nonsense that crept in.
*	simplify and optimize pthread_mutex_trylock	Rich Felker	2011-03-08	1	-17/+16
