* `native_tls_get()`' should not check resultsKoichi Sasada2022-05-241-5/+2
| | | | caller should check the result of `native_tls_get()`.
* introduce struct `rb_native_thread`Koichi Sasada2022-04-231-2/+7
| | | | | | | | | `rb_thread_t` contained `native_thread_data_t` to represent thread implementation dependent data. This patch separates them and rename it `rb_native_thread` and point it from `rb_thraed_t`. Now, 1 Ruby thread (`rb_thread_t`) has 1 native thread (`rb_native_thread`).
* rename thread internal namingKoichi Sasada2022-04-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Now GVL is not process *Global* so this patch try to use another words. * `rb_global_vm_lock_t` -> `struct rb_thread_sched` * `gvl->owner` -> `sched->running` * `gvl->waitq` -> `sched->readyq` * `rb_gvl_init` -> `rb_thread_sched_init` * `gvl_destroy` -> `rb_thread_sched_destroy` * `gvl_acquire` -> `thread_sched_to_running` # waiting -> ready -> running * `gvl_release` -> `thread_sched_to_waiting` # running -> waiting * `gvl_yield` -> `thread_sched_yield` * `GVL_UNLOCK_BEGIN` -> `THREAD_BLOCKING_BEGIN` * `GVL_UNLOCK_END` -> `THREAD_BLOCKING_END` * removed * `rb_ractor_gvl` * `rb_vm_gvl_destroy` (not used) There are GVL functions such as `rb_thread_call_without_gvl()` yet but I don't have good name to replace them. Maybe GVL stands for "Greate Valuable Lock" or something like that.

* fix public interfaceKoichi Sasada2020-11-181-11/+0
| | | | | | | | | | | | | | | | | | To make some kind of Ractor related extensions, some functions should be exposed. * include/ruby/thread_native.h * rb_native_mutex_* * rb_native_cond_* * include/ruby/ractor.h * RB_OBJ_SHAREABLE_P(obj) * rb_ractor_shareable_p(obj) * rb_ractor_std*() * rb_cRactor and rm ractor_pub.h and rename srcdir/ractor.h to srcdir/ractor_core.h (to avoid conflict with include/ruby/ractor.h)
* introduce USE_VM_CLOCK for windows.Koichi Sasada2020-11-111-0/+2
| | | | | | | | | | | | | | | | The timer function used on windows system set timer interrupt flag of current main ractor's executing ec and thread can detect the end of time slice. However, to set all ec->interrupt_flag for all running ractors, it is requires to synchronize with other ractors. However, timer thread can not acquire the ractor-wide lock because of some limitation. To solve this issue, this patch introduces USE_VM_CLOCK compile option to introduce rb_vm_t::clock. This clock will be incremented by the timer thread and each thread can check the incrementing by comparison with previous checked clock. At last, on windows platform this patch introduces some overhead, but I think there is no critical performance issue because of this modification.
* Use language TLS specifier if it is possible.Koichi Sasada2020-10-201-0/+4
| | | | | | | To access TLS, it is faster to use language TLS specifier instead of using pthread_get/setspecific functions. Original proposal is: Use native thread locals. #3665
* Introduce Ractor mechanism for parallel executionKoichi Sasada2020-09-031-0/+31
| | | | | | | | | | | | | | | | 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.
* add #include guard hack卜部昌平2020-04-131-3/+2
| | | | | | | | | | | | | | | | | | | | | | According to MSVC manual (*1), cl.exe can skip including a header file when that: - contains #pragma once, or - starts with #ifndef, or - starts with #if ! defined. GCC has a similar trick (*2), but it acts more stricter (e. g. there must be _no tokens_ outside of #ifndef...#endif). Sun C lacked #pragma once for a looong time. Oracle Developer Studio 12.5 finally implemented it, but we cannot assume such recent version. This changeset modifies header files so that each of them include strictly one #ifndef...#endif. I believe this is the most portable way to trigger compiler optimizations.

* * ext/openssl/depend: remove dependency from internal headers.ko12014-05-141-9/+0

These wrapper functions are used by MRI implementation. * vm_core.h: use include/ruby/thread_native.h. * thread.c: ditto. * thread_pthread.h: ditto. * thread_win32.h: ditto. * thread_native.h: removed. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@45944 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

And declare several functions "rb_nativethread_lock_*", manipulate locking. * common.mk: add thread_native.h. * thread.c: add functions "rb_nativethread_lock_*". * thraed.c, thread_[pthread,win32].[ch]: rename rb_thread_lock_t to rb_nativethread_lock_t to make it clear that this lock is for native thraeds, not for ruby threads. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42133 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | * thread_win32.h (rb_thread_lock_t): make a union for USE_WIN32_MUTEX. this internal is used only in thread_win32.c, but has to be complete to define rb_thread_t. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36119 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | | | * thread_win32.h (rb_thread_cond_struct): add prev field instead of last. (ie cond_event_entry is now using double linked list instead of single) * thread_win32.c (cond_event_entry): add prev field. * thread_win32.c (__cond_timedwait): remove entry properly if timeout was happen. * thread_win32.c (native_cond_signal): change for double linked list. * thread_win32.c (native_cond_broadcast): ditto. * thread_win32.c (native_cond_initialize): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@31459 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* * thread.c, vm_core.h: make gvl_acquire/release/init/destructko12010-11-271-1/+8
| | | | | | | | | | | | | | | | | | | | APIs to modularize GVL implementation. * thread_pthread.c, thread_pthread.h: Two GVL implementations. (1) Simple locking GVL which is same as existing GVL. (2) Wake-up queued threads. The wake-up order is simple FIFO. (We can make several queues to support exact priorities, however this causes some issues such as priority inversion and so on.) This impl. prevents spin-loop (*1) caused on SMP environemnts. *1: Only one Ruby thread acqures GVL again and again. Bug #2359 [ruby-core:26694] * thread_win32.c, thread_win32.h: Using simple lock not by CRITICAL_SECTION but by Mutex.
