| 2011-03-12 | misplaced & in times() made it fail to work, and clobber the stack | Rich Felker | -1/+1 | |
| 2011-03-12 | implement flockfile api, rework stdio locking | Rich Felker | -15/+66 | |
| 2011-03-11 | implement dummy pthread_attr_[gs]etschedparam functions | Rich Felker | -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. | ||||
| 2011-03-11 | fix pthread_attr_* implementations to match corrected prototypes | Rich Felker | -4/+4 | |
| 2011-03-10 | fix failure behavior of sem_open when sem does not exist | Rich Felker | -1/+5 | |
| 2011-03-10 | fix some semaphore wait semantics (race condition deadlock and error checking) | Rich Felker | -1/+7 | |
| 2011-03-10 | fix sem_open and sem_close to obey posix semantics | Rich Felker | -38/+85 | |
| 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. | ||||
| 2011-03-10 | optimize pthread termination in the non-detached case | Rich Felker | -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. | ||||
| 2011-03-10 | fix errors in sigqueue (potential information leak, wrong behavior) | Rich Felker | -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. | ||||
| 2011-03-10 | security fix: check that cancel/rsyscall signal was sent by the process itself | Rich Felker | -0/+3 | |
| 2011-03-10 | more cancellation points: tcdrain, clock_nanosleep | Rich Felker | -2/+12 | |
| 2011-03-10 | remove useless return value checks for functions that cannot fail | Rich Felker | -3/+2 | |
| 2011-03-10 | make sigsuspend a cancellation point | Rich Felker | -1/+6 | |
| 2011-03-10 | make sigtimedwait a cancellation point | Rich Felker | -0/+3 | |
| 2011-03-10 | don't fail with EINTR in sigtimedwait | Rich Felker | -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. | ||||
| 2011-03-10 | fix sigsuspend syscall | Rich Felker | -1/+1 | |
| 2011-03-10 | make sigaltstack work (missing macros in signal.h, error conditions) | Rich Felker | -1/+11 | |
| 2011-03-10 | fix errno behavior in clock_* functions | Rich Felker | -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. | ||||
| 2011-03-09 | fix error handling for pthread_sigmask | Rich Felker | -1/+15 | |
| it must return errno, not -1, and should reject invalud values for how. | ||||
| 2011-03-09 | make fork properly initialize the main thread in the child process | Rich Felker | -0/+7 | |
| 2011-03-09 | optimize pthread initialization | Rich Felker | -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. | ||||
| 2011-03-09 | fix race condition in raise - just mask signals | Rich Felker | -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. | ||||
| 2011-03-09 | fix raise semantics with threads. | Rich Felker | -1/+12 | |
| 2011-03-08 | simplify and optimize pthread_mutex_trylock | Rich Felker | -17/+16 | |
| 2011-03-08 | rwlock trylock functions were wrongly returning EAGAIN instead of EBUSY | Rich Felker | -3/+3 | |
| 2011-03-08 | fix major breakage in pthread_once (it was always deadlocking) | Rich Felker | -8/+7 | |
| 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. | ||||
| 2011-03-08 | fix and optimize non-default-type mutex behavior | Rich Felker | -25/+19 | |
| problem 1: mutex type from the attribute was being ignored by pthread_mutex_init, so recursive/errorchecking mutexes were never being used at all. problem 2: ownership of recursive mutexes was not being enforced at unlock time. | ||||
| 2011-03-08 | implement pthread_mutexattr_[gs]etpshared functions | Rich Felker | -0/+16 | |
| 2011-03-08 | disallow cpu time clocks as condattr clock values | Rich Felker | -1/+1 | |
| 2011-03-07 | fix off-by-one error in sem_(timed)wait (using old sem value instead of new) | Rich Felker | -1/+1 | |
| 2011-03-07 | use the selected clock from the condattr for pthread_cond_timedwait | Rich Felker | -1/+3 | |
| 2011-03-07 | implement pthread_rwlockattr_* (essentially no-ops) | Rich Felker | -0/+28 | |
| 2011-03-07 | implement pthread_condattr_* interfaces | Rich Felker | -0/+45 | |
| note that, while the attributes are stored, they are not used in pthread_cond_init yet. | ||||
| 2011-03-07 | reject invalid attribute settings | Rich Felker | -0/+2 | |
| note that this is a pedantic conformance issue and waste of code. it only affects broken code or code that is probing for conformance. | ||||
| 2011-03-07 | implement barrier attribute functions (essentially no-ops) | Rich Felker | -0/+27 | |
| 2011-03-04 | enforce stack size min in pthread_attr_setstacksize | Rich Felker | -1/+1 | |
| 2011-03-04 | implement POSIX semaphores | Rich Felker | -0/+201 | |
| 2011-03-03 | optimize POSIX TSD for fast pthread_getspecific | Rich Felker | -9/+14 | |
| 2011-03-03 | implement POSIX shared memory | Rich Felker | -0/+42 | |
| 2011-03-01 | depends on settimeofday which needs _GNU_SOURCE feature test | Rich Felker | -0/+1 | |
| 2011-02-27 | implement futimens and utimensat | Rich Felker | -0/+13 | |
| 2011-02-27 | implement fexecve | Rich Felker | -0/+10 | |
| 2011-02-27 | cleanup utf-8 multibyte code, use visibility if possible | Rich Felker | -84/+5 | |
| this code was written independently of musl, with support for a the backwards, nonstandard "31-bit unicode" some libraries/apps might want. unfortunately the extra code (inside #ifdef) makes the source harder to read and makes code that should be simple look complex, so i'm removing it. anyone who wants to use the old code can find it in the history or from elsewhere. also, change the visibility of the __fsmu8 state machine table to hidden, if supported. this should improve performance slightly in shared-library builds. | ||||
| 2011-02-26 | fix missing prototype for strsignal | Rich Felker | -0/+1 | |
| 2011-02-24 | various changes in preparation for dynamic linking support | Rich Felker | -5/+21 | |
| prefer using visibility=hidden for __libc internal data, rather than an accessor function, if the compiler has visibility. optimize with -O3 for PIC targets (shared library). without heavy inlining, reloading the GOT register in small functions kills performance. 20-30% size increase for a single libc.so is not a big deal, compared to comparaible size increase in every static binaries. use -Bsymbolic-functions, not -Bsymbolic. global variables are subject to COPY relocations, and thus binding their addresses in the library at link time will cause library functions to read the wrong (original) copies instead of the copies made in the main program's bss section. add entry point, _start, for dynamic linker. | ||||
| 2011-02-24 | add implementation of memccpy function | Rich Felker | -0/+32 | |
| 2011-02-24 | fix backwards conditional in stpncpy | Rich Felker | -1/+1 | |
| this only made the function unnecessarily slow on systems with unaligned access, but would of course crash on systems that can't do unaligned accesses (none of which have ports yet). | ||||
| 2011-02-22 | rewind must clear the error indicator in addition to seeking | Rich Felker | -2/+5 | |
| 2011-02-21 | change errno to static linkage (improves PIC code generation) | Rich Felker | -4/+2 | |
| 2011-02-21 | remove sample utf-8 code that's not part of the standard library | Rich Felker | -47/+0 | |
