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. --- ractor_pub.h | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 ractor_pub.h (limited to 'ractor_pub.h') diff --git a/ractor_pub.h b/ractor_pub.h new file mode 100644 index 0000000000..5062782b5a --- /dev/null +++ b/ractor_pub.h @@ -0,0 +1,33 @@ + +int rb_ractor_main_p(void); + +bool rb_ractor_shareable_p_continue(VALUE obj); + +#define RB_OBJ_SHAREABLE_P(obj) FL_TEST_RAW((obj), RUBY_FL_SHAREABLE) + +// TODO: deep frozen + +static inline bool +rb_ractor_shareable_p(VALUE obj) +{ + if (SPECIAL_CONST_P(obj)) { + return true; + } + else if (RB_OBJ_SHAREABLE_P(obj)) { + return true; + } + else { + return rb_ractor_shareable_p_continue(obj); + } +} + +RUBY_SYMBOL_EXPORT_BEGIN + +VALUE rb_ractor_stdin(void); +VALUE rb_ractor_stdout(void); +VALUE rb_ractor_stderr(void); +void rb_ractor_stdin_set(VALUE); +void rb_ractor_stdout_set(VALUE); +void rb_ractor_stderr_set(VALUE); + +RUBY_SYMBOL_EXPORT_END -- cgit v1.2.3
