Ruby's multi-threading

#Thread #1 is running Herethread. New {  #Thread #This  code} #Thread # This code

Thread.new is synonymous with Thread.Start and thread.for.

The value of the last expression in the code block is the value of the thread, which can be obtained by invoking the value of the thread object.

The thread.current represents the thread object for the current threads.

Thread.main is the main thread that represents the beginning of the Ruby program

Thread.Join blocking the current thread knows that the join thread has finished executing

Thread.abort_on_exception = True if there are unhandled exceptions exit the interpreter

Threads can store data that is part of a thread

thread.current['count'] = 0puts thread.current['count' ]

Thread Mutex

#!/usr/bin/rubyRequire'Thread'Mutex=Mutex.newcount1= Count2 =0difference=0counter=thread.new Do loop does mutex.synchronize do count1+ = 1Count2+ = 1End Endendspy=thread.new Do loop does mutex.synchronize do difference+ = (Count1-count2). ABS End Endendsleep1mutex.lockputs"count1: #{count1}"puts"count2: #{count2}"puts"difference: #{difference}"

Thread state

Thread State	Return value
Runnable	Run
Sleeping	Sleeping
Aborting	Aborting
Terminated normally	False
Terminated Width exception	Nil

# !/usr/bin/ruby  = thread.new do   #  calling a class method new puts "in second Thread"   raise
   
     "
    Raise exception
