2020-11-18fix public interfaceKoichi Sasada
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) Notes: Merged: https://github.com/ruby/ruby/pull/3775
2020-11-11introduce USE_VM_CLOCK for windows.Koichi Sasada
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.

2020-10-20Use language TLS specifier if it is possible.Koichi Sasada
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 Notes: Merged: https://github.com/ruby/ruby/pull/3667
2020-09-03Introduce Ractor mechanism for parallel executionKoichi Sasada
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. Notes: Merged: https://github.com/ruby/ruby/pull/3365
2020-04-13add #include guard hack卜部昌平
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.
