2020-04-16Canonicalize config.h includeSebastian Huber
Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
2018-02-08Use _Thread_Dispatch_direct()Sebastian Huber
Use _Thread_Dispatch_direct() for operations that block the executing thread. This ensures that we get a fatal error (INTERNAL_ERROR_BAD_THREAD_DISPATCH_DISABLE_LEVEL) if we try to block in an invalid context, e.g. during system start or an interrupt handler.
2016-05-20posix: Rework thread cancellationSebastian Huber
Add Thread_Life_state::THREAD_LIFE_CHANGE_DEFERRED and rework the POSIX thread cancellation to use the thread life states. Update #2555. Update #2626.
2016-05-20posix: Rework pthread_join()Sebastian Huber
Rework pthread_join() to use _Thread_Join(). Close #2402. Update #2555. Update #2626. Close #2714.
2016-05-20score: Avoid superfluous life protectionSebastian Huber
Disable thread dispatching is enough to prevent deletion of the executing thread. There is no need for an additional life protection. Update #2555. Update #2626.
2016-05-20score: Add _Thread_Exit()Sebastian Huber
The goal is to make _Thread_Exit() a no-return function in follow up patches. Update #2555. Update #2626.
2016-03-29score: Remove Thread_queue_Queue::operations fieldSebastian Huber
Remove the Thread_queue_Queue::operations field to reduce the size of this structure. Add a thread queue operations parameter to the _Thread_queue_First(), _Thread_queue_First_locked(), _Thread_queue_Enqueue(), _Thread_queue_Dequeue() and _Thread_queue_Flush() functions. This is a preparation patch to reduce the size of several synchronization objects.
2016-03-23posix: pthread_exit() is a no-return functionSebastian Huber
2014-05-15score: Simplify _Thread_Change_priority()Sebastian Huber
The function to change a thread priority was too complex. Simplify it with a new scheduler operation. This increases the average case performance due to the simplified logic. The interrupt disabled critical section is a bit prolonged since now the extract, update and enqueue steps are executed atomically. This should however not impact the worst-case interrupt latency since at least for the Deterministic Priority Scheduler this sequence can be carried out with a wee bit of instructions and no loops. Add _Scheduler_Change_priority() to replace the sequence of - _Thread_Set_transient(), - _Scheduler_Extract(), - _Scheduler_Enqueue(), and - _Scheduler_Enqueue_first(). Delete STATES_TRANSIENT, _States_Is_transient() and _Thread_Set_transient() since this state is now superfluous. With this change it is possible to get rid of the SCHEDULER_SMP_NODE_IN_THE_AIR state. This considerably simplifies the implementation of the new SMP locking protocols.
2014-03-31score: Thread life cycle re-implementationSebastian Huber
The thread deletion is now supported on SMP. This change fixes the following PRs: PR1814: SMP race condition between stack free and dispatch PR2035: psxcancel reveals NULL pointer access in _Thread_queue_Extract() The POSIX cleanup handler are now called in the right context (should be called in the context of the terminating thread). http://pubs.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_09.html Add a user extension the reflects a thread termination event. This is used to reclaim the Newlib reentrancy structure (may use file operations), the POSIX cleanup handlers and the POSIX key destructors.

2013-07-26score: Create threadq implementation headerSebastian Huber
Move implementation specific parts of tqdata.h, threadq.h and threadq.inl into new header file threadqimpl.h. The threadq.h contains now only the application visible API. Delete tqdata.h.
2013-07-26score: Create thread implementation headerSebastian Huber
Move implementation specific parts of thread.h and thread.inl into new header file threadimpl.h. The thread.h contains now only the application visible API. Remove superfluous header file includes from various files.
2013-07-22posix: Create pthread implementation headerSebastian Huber
Move implementation specific parts of pthread.h and pthread.inl into new header file pthreadimpl.h. The pthread.h contains now only the application visible API.
2013-07-22posix: Use _Thread_Get_executing()Sebastian Huber
2013-06-07score: Add and use _Objects_Put()Sebastian Huber
Add and use _Objects_Put_without_thread_dispatch(). These two functions pair with the _Objects_Get() function. This helps to introduce object specific SMP locks to avoid lock contention.

2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.

PR 1867/cpukit * posix/src/pthreadexit.c, posix/src/pthreadjoin.c: Correct implementation of pthread_exit() and pthread_join() to support the case where a thread is joinable but calls pthread_exit() before a thread has attempted to join.
