From 79df14c04b452411b9d17e26a398e491bca1a811 Mon Sep 17 00:00:00 2001 From: Koichi Sasada Date: Tue, 10 Mar 2020 02:22:11 +0900 Subject: Introduce Ractor mechanism for parallel execution This commit introduces Ractor mechanism to run Ruby program in parallel. See doc/ractor.md for more details about Ractor. See ticket [Feature #17100] to see the implementation details and discussions. [Feature #17100] This commit does not complete the implementation. You can find many bugs on using Ractor. Also the specification will be changed so that this feature is experimental. You will see a warning when you make the first Ractor with `Ractor.new`. I hope this feature can help programmers from thread-safety issues. --- thread_pthread.h | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) (limited to 'thread_pthread.h') diff --git a/thread_pthread.h b/thread_pthread.h index 27b22103c6..d14857b05a 100644 --- a/thread_pthread.h +++ b/thread_pthread.h @@ -39,6 +39,18 @@ typedef struct native_thread_data_struct { } cond; } native_thread_data_t; +void rb_native_mutex_lock(rb_nativethread_lock_t *lock); +int rb_native_mutex_trylock(rb_nativethread_lock_t *lock); +void rb_native_mutex_unlock(rb_nativethread_lock_t *lock); +void rb_native_mutex_initialize(rb_nativethread_lock_t *lock); +void rb_native_mutex_destroy(rb_nativethread_lock_t *lock); +void rb_native_cond_signal(rb_nativethread_cond_t *cond); +void rb_native_cond_broadcast(rb_nativethread_cond_t *cond); +void rb_native_cond_wait(rb_nativethread_cond_t *cond, rb_nativethread_lock_t *mutex); +void rb_native_cond_timedwait(rb_nativethread_cond_t *cond, rb_nativethread_lock_t *mutex, unsigned long msec); +void rb_native_cond_initialize(rb_nativethread_cond_t *cond); +void rb_native_cond_destroy(rb_nativethread_cond_t *cond); + #undef except #undef try #undef leave @@ -71,4 +83,24 @@ typedef struct rb_global_vm_lock_struct { int wait_yield; } rb_global_vm_lock_t; +typedef pthread_key_t native_tls_key_t; + +static inline void * +native_tls_get(native_tls_key_t key) +{ + void *ptr = pthread_getspecific(key); + if (UNLIKELY(ptr == NULL)) { + rb_bug("pthread_getspecific returns NULL"); + } + return ptr; +} + +static inline void +native_tls_set(native_tls_key_t key, void *ptr) +{ + if (UNLIKELY(pthread_setspecific(key, ptr) != 0)) { + rb_bug("pthread_setspecific error"); + } +} + #endif /* RUBY_THREAD_PTHREAD_H */ -- cgit v1.2.1
