Rich Felker	836ba93d93	__syscall5 inline is having trouble with PIC; just use the function for now	15 years ago
Rich Felker	7779dbd266	fix race condition in pthread_kill if thread id was reused by the kernel between the time pthread_kill read it from the userspace pthread_t object and the time of the tgkill syscall, a signal could be sent to the wrong thread. the tgkill syscall was supposed to prevent this race (versus the old tkill syscall) but it can't; it can only help in the case where the tid is reused in a different process, but not when the tid is reused in the same process. the only solution i can see is an extra lock to prevent threads from exiting while another thread is trying to pthread_kill them. it should be very very cheap in the non-contended case.	15 years ago
Rich Felker	f58c8a0f39	run dtors before taking the exit-lock in pthread exit previously a long-running dtor could cause pthread_detach to block.	15 years ago
Rich Felker	6232b96f51	minor locking optimizations	15 years ago
Rich Felker	0e1762539c	avoid 64bit warnings when using pointers as entropy for temp names	15 years ago
Rich Felker	f09e78de98	fix sigset macro for 64-bit systems (<< was overflowing due to wrong type)	15 years ago
Rich Felker	1e4f1cf154	remove all .size and .type directives for functions from the asm these are useless and have caused problems for users trying to build with non-gnu tools like tcc's assembler.	15 years ago
Rich Felker	76100a724e	remove old useless timezone.s file (unused)	15 years ago
Rich Felker	73d2fde119	fix wrong type for wcsrchr argument 2	15 years ago
Rich Felker	773b0fe447	x86_64 fenv support (untested; at least known to build successfully)	15 years ago
Rich Felker	52cf24a0f4	fix fesetround - it was writing to status word instead of control word	15 years ago
Rich Felker	b09b78905b	floating point environment, untested at present the i386 code does not support sse floating point, which is not part of the standard i386 abi. while it may be desirable to support it later, doing so will reduce performance and require some tricks to probe if sse support is present. this first commit is i386-only, but it should be trivial to port the asm to x86_64.	15 years ago
Rich Felker	2afebbbcd1	malloc: cast size down to int in bin_index functions even if size_t was 32-bit already, the fact that the value was unsigned and that gcc is too stupid to figure out it would be positive as a signed quantity (due to the immediately-prior arithmetic and conditionals) results in gcc compiling the integer-to-float conversion as zero extension to 64 bits followed by an "fildll" (64 bit) instruction rather than a simple "fildl" (32 bit) instruction on x86. reportedly fildll is very slow on certain p4-class machines; even if not, the new code is slightly smaller.	15 years ago

Rich Felker	2697b4e755	add netpacket/packet.h looks like busybox is going to want it, and apparently some other low-level network software does too...	15 years ago
Rich Felker	c19a6be5a1	it's called getgrgid_r, not getgruid_r...	15 years ago

Rich Felker	e1d2a8e239	mq names without leading / have impl-def behavior; allowing them is easier	15 years ago
Rich Felker	2b0cedac8d	define MQ_PRIO_MAX	15 years ago
Rich Felker	0b6b43ed3f	use __WCHAR_TYPE__ on i386 if it is defined unfortunately traditional i386 practice was to use "long" rather than "int" for wchar_t, despite the latter being much more natural and logical. we followed this practice, but it seems some compilers (clang and maybe certain gcc builds or others too..?) have switched to using int, resulting in spurious pointer type mismatches when L"..." wide strings are used. the best solution I could find is to use the compiler's definition of wchar_t if it exists, and otherwise fallback to the traditional definition. there's no point in duplicating this approach on 64-bit archs, as their only 32-bit type is int.	15 years ago
Rich Felker	86f8c72bb1	mq send/recv functions are cancellation points	15 years ago
Rich Felker	ede353d8e5	implement mq_notify	15 years ago
Rich Felker	ab11386aaa	add support for POSIX message queues, except mq_notify	15 years ago
Rich Felker	cbf35978a9	use __attribute__((const)) for errno and pthread_self if __GNUC__ is defined this is not too ugly and should result in significant code size and performance improvements for many programs.	15 years ago
Rich Felker	71a80c5767	use volatile pointers for intentional-crash code.	15 years ago
Rich Felker	da88b16a22	fix handling of d_name in struct dirent basically there are 3 choices for how to implement this variable-size string member: 1. C99 flexible array member: breaks using dirent.h with pre-C99 compiler. 2. old way: length-1 string: generates array bounds warnings in caller. 3. new way: length-NAME_MAX string. no problems, simplifies all code. of course the usable part in the pointer returned by readdir might be shorter than NAME_MAX+1 bytes, but that is allowed by the standard and doesn't hurt anything.	15 years ago
Rich Felker	0dc99ac413	safety fix for glob's vla usage: disallow patterns longer than PATH_MAX this actually inadvertently disallows some valid patterns with redundant / or * characters, but it's better than allowing unbounded vla allocation. eventually i'll write code to move the pattern to the stack and eliminate redundancy to ensure that it fits in PATH_MAX at the beginning of glob. this would also allow it to be modified in place for passing to fnmatch rather than copied at each level of recursion.	15 years ago
Rich Felker	a6c399cf62	eliminate (harmless in this case) vla usage in fnmatch.c	15 years ago
Rich Felker	c74d306f47	missing prototypes for mbsnrtowcs and wcsnrtombs	15 years ago
Rich Felker	ddd87b2f10	implement pthread_[sg]etconcurrency. there is a resource limit of 0 bits to store the concurrency level requested. thus any positive level exceeds a resource limit, resulting in EAGAIN. :-)	15 years ago
Rich Felker	11c531e21d	implement uselocale function (minimal)	15 years ago
Rich Felker	9a59faab3c	add useless, obsolescent function ulimit	15 years ago
Rich Felker	f48832ee15	fix backwards posix_spawn file action order	15 years ago

Rich Felker	d6c0c97846	posix_spawn: honor POSIX_SPAWN_SETSIGDEF flag	15 years ago
Rich Felker	c97f0d998c	initial implementation of posix_spawn file actions are not yet implemented, but everything else should be mostly complete and roughly correct.	15 years ago
Rich Felker	3a17f757a8	modernize coding style in sjlj asm	15 years ago
Rich Felker	86339bc4ba	fix strncat and wcsncat (double null termination) also modify wcsncpy to use the same loop logic	15 years ago
Rich Felker	e98136207a	fix wcsncpy writing past end of buffer	15 years ago
Rich Felker	19892bf0a7	fix brk/sbrk behavior to match the real legacy functions	15 years ago
Rich Felker	c5025bfabe	release notes for 0.7.10	15 years ago
Rich Felker	8628eff912	fix the last known rounding bug in floating point printing the observed symptom was that the code was incorrectly rounding up 1.0625 to 1.063 despite the rounding mode being round-to-nearest with ties broken by rounding to even last place. however, the code was just not right in many respects, and i'm surprised it worked as well as it did. this time i tested the values that end up in the variables round, small, and the expression round+small, and all look good.	15 years ago
Rich Felker	15b77d52c9	eventfd syscall wrapper and read/write wrappers	15 years ago
Rich Felker	11e4b92556	optimize out useless default-attribute object in pthread_create	15 years ago
Rich Felker	4c4e22d781	optimize compound-literal sigset_t's not to contain useless hurd bits	15 years ago
Rich Felker	99b8a25e94	overhaul implementation-internal signal protections 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.	15 years ago
Rich Felker	77f15d108e	reduce some ridiculously large spin counts these should be tweaked according to testing. offhand i know 1000 is too low and 5000 is likely to be sufficiently high. consider trying to add futexes to file locking, too...	15 years ago
Rich Felker	9dd6399c95	remove debug code that was missed in barrier commit	15 years ago
