| 2011-03-12 | misplaced & in times() made it fail to work, and clobber the stack | Rich Felker | 1 | -1/+1 |
| 2011-03-12 | implement flockfile api, rework stdio locking | Rich Felker | 9 | -15/+66 |
| 2011-03-12 | 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.

| 2011-03-11 | document some additional important changes | Rich Felker | 1 | -1/+2 |
| 2011-03-11 | update whatsnew file for release of 0.7.0 | Rich Felker | 1 | -2/+4 |
| 2011-03-11 | match dimensions so we can use all slots without invoking OOB-array-access | Rich Felker | 2 | -10/+10 |
| 2011-03-11 | 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.
| Rich Felker | 2 | -0/+14 |
| 2011-03-11 | fix pthread_attr_* implementations to match corrected prototypes | Rich Felker | 4 | -4/+4 |

| 2011-03-11 | list major changes in preparation for release | Rich Felker | 1 | -0/+23 |
| 2011-03-10 | fix failure behavior of sem_open when sem does not exist | Rich Felker | 1 | -1/+5 |
| 2011-03-10 | fix some semaphore wait semantics (race condition deadlock and error checking) | Rich Felker | 2 | -1/+7 |
| 2011-03-10 | 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.
| Rich Felker | 4 | -38/+86 |
| 2011-03-10 | 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.
| Rich Felker | 2 | -4/+16 |
| 2011-03-10 | 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.
| Rich Felker | 1 | -5/+7 |
| 2011-03-10 | security fix: check that cancel/rsyscall signal was sent by the process itself | Rich Felker | 1 | -0/+3 |
| 2011-03-10 | more cancellation points: tcdrain, clock_nanosleep | Rich Felker | 2 | -2/+12 |
| 2011-03-10 | remove useless return value checks for functions that cannot fail | Rich Felker | 1 | -3/+2 |
| 2011-03-10 | make sigsuspend a cancellation point | Rich Felker | 1 | -1/+6 |
| 2011-03-10 | make sigtimedwait a cancellation point | Rich Felker | 1 | -0/+3 |
| 2011-03-10 | 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.
| Rich Felker | 1 | -6/+6 |
| 2011-03-10 | fix sigsuspend syscall | Rich Felker | 1 | -1/+1 |
| 2011-03-10 | make sigaltstack work (missing macros in signal.h, error conditions) | Rich Felker | 3 | -1/+15 |
| 2011-03-10 | 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.
| Rich Felker | 3 | -3/+0 |
| 2011-03-09 | fix error handling for pthread_sigmask•••it must return errno, not -1, and should reject invalud values for how.
| Rich Felker | 2 | -1/+15 |
| 2011-03-09 | make fork properly initialize the main thread in the child process | Rich Felker | 1 | -0/+7 |
| 2011-03-09 | 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.
| Rich Felker | 1 | -2/+2 |
| 2011-03-09 | 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.
| Rich Felker | 1 | -9/+9 |
| 2011-03-09 | fix raise semantics with threads. | Rich Felker | 1 | -1/+12 |
| 2011-03-08 | fix typos in dirent.h | Rich Felker | 1 | -2/+2 |
| 2011-03-08 | fcntl.h should make availabel the mode constants from sys/stat.h•••also remove some legacy nonsense that crept in.
| Rich Felker | 2 | -8/+20 |
| 2011-03-08 | simplify and optimize pthread_mutex_trylock | Rich Felker | 1 | -17/+16 |
| 2011-03-08 | rwlock trylock functions were wrongly returning EAGAIN instead of EBUSY | Rich Felker | 2 | -3/+3 |
| 2011-03-08 | 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.
| Rich Felker | 1 | -8/+7 |
| 2011-03-08 | fix and optimize non-default-type mutex behavior•••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.
| Rich Felker | 4 | -25/+19 |
| 2011-03-08 | implement pthread_mutexattr_[gs]etpshared functions | Rich Felker | 2 | -0/+16 |
| 2011-03-08 | disallow cpu time clocks as condattr clock values | Rich Felker | 1 | -1/+1 |
| 2011-03-07 | add macros for use with d_type extension field in dirent | Rich Felker | 1 | -0/+14 |
| 2011-03-07 | fix off-by-one error in sem_(timed)wait (using old sem value instead of new) | Rich Felker | 1 | -1/+1 |
| 2011-03-07 | use the selected clock from the condattr for pthread_cond_timedwait | Rich Felker | 3 | -1/+3 |
| 2011-03-07 | add prototypes for pthread_condattr_* and pthread_rwlockattr_* | Rich Felker | 1 | -0/+12 |
| 2011-03-07 | implement pthread_rwlockattr_* (essentially no-ops) | Rich Felker | 4 | -0/+28 |
| 2011-03-07 | implement pthread_condattr_* interfaces•••note that, while the attributes are stored, they are not used in
pthread_cond_init yet.
| Rich Felker | 6 | -0/+45 |
| 2011-03-07 | reject invalid attribute settings•••note that this is a pedantic conformance issue and waste of code. it
only affects broken code or code that is probing for conformance.
| Rich Felker | 2 | -0/+2 |
