Rich Felker	c35bb6645f	implement wprintf family of functions 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.	15 years ago
Rich Felker	a012aa879f	fix broken wmemchr (unbounded search)	15 years ago
Rich Felker	047e434ef5	implement robust mutexes 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.	15 years ago
Rich Felker	18c7ea8055	avoid function call to pthread_self in mutex unlock 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.	15 years ago
Rich Felker	93cc986ab3	reorder mutex struct fields to make room for pointers (upcoming robust mutexes) 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.	15 years ago
Rich Felker	b1c43161c2	unify lock and owner fields of mutex structure 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.	15 years ago
Rich Felker	e914f8b7ec	optimize contended normal mutex case; add int compare-and-swap atomic	15 years ago
Rich Felker	1d59f1eddb	simplify logic, slightly optimize contended case for non-default mutex types	15 years ago
Rich Felker	d4f9e0b364	correct error returns for error-checking mutexes	15 years ago
Rich Felker	29fae65780	cut out a syscall on thread creation in the case where guard size is 0	15 years ago
Rich Felker	cc832d8a31	don't expose EAGAIN, etc. from timed futex wait to caller	15 years ago
Rich Felker	4d9cc0b399	optimize file locking: avoid cache-polluting writes to global storage	15 years ago
Rich Felker	9dd7d7e3f6	partially-written draft of fmemopen, still in #if 0	15 years ago
Rich Felker	b446c55b6f	remove some old cruft from sys/types.h	15 years ago
Rich Felker	eff62b8a96	misplaced & in times() made it fail to work, and clobber the stack	15 years ago
Rich Felker	5eb0d33ec0	implement flockfile api, rework stdio locking	15 years ago
Rich Felker	d8d19f4d46	pthread.h needs clockid_t 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.	15 years ago
Rich Felker	9f50b77d2b	document some additional important changes	15 years ago
Rich Felker	6f05b6bbd5	update whatsnew file for release of 0.7.0	15 years ago
Rich Felker	8bb0e48889	match dimensions so we can use all slots without invoking OOB-array-access	15 years ago
Rich Felker	243b542382	implement dummy pthread_attr_[gs]etschedparam functions 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.	15 years ago
Rich Felker	1659aa0e62	fix pthread_attr_* implementations to match corrected prototypes	15 years ago
Rich Felker	cabf2ff349	fix missing ENOTSUP error code	15 years ago
Rich Felker	f1821fce81	missing const in some pthread_attr_* prototypes	15 years ago
Rich Felker	2676198733	formatting whatsnew file	15 years ago
Rich Felker	8d07a0350e	list major changes in preparation for release	15 years ago
Rich Felker	682a0f271f	fix failure behavior of sem_open when sem does not exist	15 years ago
Rich Felker	cfe581b6bc	fix some semaphore wait semantics (race condition deadlock and error checking)	15 years ago
Rich Felker	81af503610	fix sem_open and sem_close to obey posix semantics 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.	15 years ago
Rich Felker	5fcebcde6a	optimize pthread termination in the non-detached case 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.	15 years ago
Rich Felker	dc54a7cbb9	fix errors in sigqueue (potential information leak, wrong behavior) 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.	15 years ago
Rich Felker	52213f7341	security fix: check that cancel/rsyscall signal was sent by the process itself	15 years ago
Rich Felker	11dbbe9fba	more cancellation points: tcdrain, clock_nanosleep	15 years ago
Rich Felker	c8c4ef7d44	remove useless return value checks for functions that cannot fail	15 years ago
Rich Felker	0f8cc94d68	make sigsuspend a cancellation point	15 years ago
Rich Felker	5b9429adb7	make sigtimedwait a cancellation point	15 years ago
Rich Felker	0a949ebdf0	don't fail with EINTR in sigtimedwait 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.	15 years ago
Rich Felker	0558683d3d	fix sigsuspend syscall	15 years ago
Rich Felker	6871fd773d	make sigaltstack work (missing macros in signal.h, error conditions)	15 years ago
Rich Felker	1b538acb0a	fix errno behavior in clock_* functions 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.	15 years ago
Rich Felker	500c969f05	fix error handling for pthread_sigmask it must return errno, not -1, and should reject invalud values for how.	15 years ago
Rich Felker	3f5420bcda	make fork properly initialize the main thread in the child process	15 years ago
Rich Felker	6dc05fbe19	optimize pthread initialization 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.	15 years ago
Rich Felker	0bed7e0acf	fix race condition in raise - just mask signals 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.	15 years ago
Rich Felker	370f78f2c8	fix raise semantics with threads.	15 years ago
Rich Felker	91f7db2621	fix typos in dirent.h	15 years ago
Rich Felker	ac12eb91bd	fcntl.h should make availabel the mode constants from sys/stat.h also remove some legacy nonsense that crept in.	15 years ago
Rich Felker	31e06075d5	simplify and optimize pthread_mutex_trylock	15 years ago
Rich Felker	e5dd18319b	rwlock trylock functions were wrongly returning EAGAIN instead of EBUSY	15 years ago
Rich Felker	7e6be42a77	fix major breakage in pthread_once (it was always deadlocking) the issue was a break statement that was breaking only from the switch, not the enclosing for loop, and a failure to set the final success state.	15 years ago
