#Thread #1 is running here Thread.new{ #Thread #2 runs this code } #Thread #1 runs this code
Thread.new的同义词是Thread.start和Thread.for
代码块中的最后一个表达式的值是线程的值，可以通过调用Thread对象的值的方法获得。
Thread.current 表示当前线程的Thread对象。
Thread.main 代表ruby程序的开始时的主线程
Thread.join 阻塞当前线程知道join的线程执行完毕
Thread.abort_on_exception = true 如果有未处理的异常则退出解释器
线程中可以存储属于线程的数据
Thread.current[‘count‘] = 0 puts Thread.current[‘count‘]
线程互斥
#!/usr/bin/ruby require ‘thread‘ mutex = Mutex.new count1 = count2 = 0 difference = 0 counter = Thread.new do loop do mutex.synchronize do count1 += 1 count2 += 1 end end end spy = Thread.new do loop do mutex.synchronize do difference += (count1 - count2).abs end end end sleep 1 mutex.lock puts "count1 : #{count1}" puts "count2 : #{count2}" puts "difference : #{difference}"
线程状态
| Thread state | Return value |
| Runnable | run |
| Sleeping | Sleeping |
| Aborting | aborting |
| Terminated normally | false |
| Terminated width exception | nil |
#!/usr/bin/ruby thr = Thread.new do # Calling a class method new puts "In second thread" raise "Raise exception" end thr.join # Calling an instance method join
