* remove some old cruft from sys/types.hRich Felker2011-03-141-1/+0
|
* misplaced & in times() made it fail to work, and clobber the stackRich Felker2011-03-121-1/+1
|
* implement flockfile api, rework stdio lockingRich Felker2011-03-129-15/+66
|
* pthread.h needs clockid_tRich Felker2011-03-121-0/+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 v0.7.0Rich Felker2011-03-111-1/+2
|
* update whatsnew file for release of 0.7.0Rich Felker2011-03-111-2/+4
|
* match dimensions so we can use all slots without invoking OOB-array-accessRich Felker2011-03-112-10/+10
|
* implement dummy pthread_attr_[gs]etschedparam functionsRich Felker2011-03-112-0/+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 prototypesRich Felker2011-03-114-4/+4
|
* fix missing ENOTSUP error codeRich Felker2011-03-112-0/+2
|
* missing const in some pthread_attr_* prototypesRich Felker2011-03-111-8/+8
|
* formatting whatsnew fileRich Felker2011-03-111-0/+6
|
* list major changes in preparation for releaseRich Felker2011-03-111-0/+23
|
* fix failure behavior of sem_open when sem does not existRich Felker2011-03-101-1/+5
|
* fix some semaphore wait semantics (race condition deadlock and error checking)Rich Felker2011-03-102-1/+7
|
* fix sem_open and sem_close to obey posix semanticsRich Felker2011-03-104-38/+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 caseRich Felker2011-03-102-4/+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 Felker2011-03-101-5/+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 itselfRich Felker2011-03-101-0/+3
|
* more cancellation points: tcdrain, clock_nanosleepRich Felker2011-03-102-2/+12
|
* remove useless return value checks for functions that cannot failRich Felker2011-03-101-3/+2
|
* make sigsuspend a cancellation pointRich Felker2011-03-101-1/+6
|
* make sigtimedwait a cancellation pointRich Felker2011-03-101-0/+3
|
* don't fail with EINTR in sigtimedwaitRich Felker2011-03-101-6/+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 syscallRich Felker2011-03-101-1/+1
|
* make sigaltstack work (missing macros in signal.h, error conditions)Rich Felker2011-03-103-1/+15
|
* fix errno behavior in clock_* functionsRich Felker2011-03-103-3/+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_sigmaskRich Felker2011-03-092-1/+15
| | | | it must return errno, not -1, and should reject invalud values for how.
* make fork properly initialize the main thread in the child processRich Felker2011-03-091-0/+7
|
* optimize pthread initializationRich Felker2011-03-091-2/+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 signalsRich Felker2011-03-091-9/+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 Felker2011-03-091-1/+12
|
* fix typos in dirent.hRich Felker2011-03-081-2/+2
|
* fcntl.h should make availabel the mode constants from sys/stat.hRich Felker2011-03-082-8/+20
| | | | also remove some legacy nonsense that crept in.
* simplify and optimize pthread_mutex_trylockRich Felker2011-03-081-17/+16
|
* rwlock trylock functions were wrongly returning EAGAIN instead of EBUSYRich Felker2011-03-082-3/+3
|
* fix major breakage in pthread_once (it was always deadlocking)Rich Felker2011-03-081-8/+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.
* fix and optimize non-default-type mutex behaviorRich Felker2011-03-084-25/+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.
* implement pthread_mutexattr_[gs]etpshared functionsRich Felker2011-03-082-0/+16
|
* disallow cpu time clocks as condattr clock valuesRich Felker2011-03-081-1/+1
|
* add macros for use with d_type extension field in direntRich Felker2011-03-071-0/+14
|
* fix off-by-one error in sem_(timed)wait (using old sem value instead of new)Rich Felker2011-03-071-1/+1
|
* use the selected clock from the condattr for pthread_cond_timedwaitRich Felker2011-03-073-1/+3
|
* add prototypes for pthread_condattr_* and pthread_rwlockattr_*Rich Felker2011-03-071-0/+12
|
* implement pthread_rwlockattr_* (essentially no-ops)Rich Felker2011-03-074-0/+28
|
* implement pthread_condattr_* interfacesRich Felker2011-03-076-0/+45
| | | | | note that, while the attributes are stored, they are not used in pthread_cond_init yet.
* reject invalid attribute settingsRich Felker2011-03-072-0/+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.
* implement barrier attribute functions (essentially no-ops)Rich Felker2011-03-074-0/+27
|
* enforce stack size min in pthread_attr_setstacksizeRich Felker2011-03-041-1/+1
|
* implement POSIX semaphoresRich Felker2011-03-0410-0/+201
