Kernel#inspectnow checks for the existence of a instance_variables_to_inspect method, allowing control over which instance variables are displayed in the inspect string:class DatabaseConfig def initialize(host, user, password) @host = host @user = user @password = password end private def instance_variables_to_inspect = [:@host, :@user] end conf = DatabaseConfig.new("localhost", "root", "hunter2") conf.inspect #=> #<DatabaseConfig:0x0000000104def350 @host="localhost", @user="root">

Ractor::Portclass was added for a new synchronization mechanism to communicate between Ractors. [Feature #21262]port1 = Ractor::Port.new port2 = Ractor::Port.new Ractor.new port1, port2 do |port1, port2| port1 << 1 port2 << 11 port1 << 2 port2 << 12 end 2.times{ p port1.receive } #=> 1, 2 2.times{ p port2.receive } #=> 11, 12
Ractor::Portprovides the following methods:As result,
Ractor.yieldandRactor#takewere removed. -
Ractor#joinandRactor#valuewere added to wait for the termination of aRactor. These are similar toThread#joinandThread#value. -
Ractor#monitorandRactor#unmonitorwere added as low-level interfaces used internally to implementRactor#join. -
Ractor.selectnow only accepts Ractors and Ports. If Ractors are given, it returns when aRactorterminates. -
Ractor#default_portwas added. EachRactorhas a default port, which is used byRactor.send,Ractor.receive. -
Ractor#close_incomingandRactor#close_outgoingwere removed.

C API updates¶ ↑
-
-
rb_thread_fd_closeis deprecated and now a no-op. If you need to expose file descriptors from C extensions to Ruby code, create anIOinstance usingRUBY_IO_MODE_EXTERNALand userb_io_close(io)to close it (this also interrupts and waits for all pending operations on theIOinstance). Directly closing file descriptors does not interrupt pending operations, and may lead to undefined behaviour. In other words, if twoIOobjects share the same file descriptor, closing one does not affect the other. [Feature #18455]
