The Ruby Programming Language [mirror]

This solves multiple problems. First, RB_VM_LOCK_ENTER/LEAVE is a barrier. We could at least use the _NO_BARRIER variant. Second, this doesn't need to interfere with GC or other GVL users when multiple Ractors are used. This needs to be used in very few places, so the benefit of fine-grained locking would outweigh its small maintenance cost. Third, it fixes a crash for YJIT. Because YJIT is never disabled until a process exits unlike MJIT that finishes earlier, we could call jit_cont_free when EC no longer exists, which crashes RB_VM_LOCK_ENTER. |

What is Ruby?
Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.
Features of Ruby
- Simple Syntax
- Normal Object-oriented Features (e.g. class, method calls)
- Advanced Object-oriented Features (e.g. mix-in, singleton-method)
- Operator Overloading
- Exception Handling
- Iterators and Closures
- Garbage Collection
- Dynamic Loading of Object Files (on some architectures)
- Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://github.com/ruby/ruby/blob/master/doc/maintainers.rdoc#label-Platform+Maintainers
