我使用python的stdin来收集来自其他进程的消息
但想要更改快速recv消息的stdin buff大小
我知道子程序可以在打开子进程进程时设置stdin buff
但我的一个过程就是发送消息的过程
另一个是recva消息的python进程
如何更改python中的stdin buff大小?
我的主机是一台linux机器..

来自an answer to a similar question:
您可以使用python' s -u标志从stdin / stdout中完全删除缓冲:
-u : unbuffered binary stdout and stderr (also PYTHONUNBUFFERED=x) see man page for details on internal buffering relating to '-u'
并且手册页澄清了:
-u Force stdin, stdout and stderr to be totally unbuffered. On systems where it matters, also put stdin, stdout and stderr in binary mode. Note that there is internal buffering in xread- lines(), readlines() and file-object iterators ("for line in sys.stdin") which is not influenced by this option. To work around this, you will want to use "sys.stdin.readline()" inside a "while 1:" loop.
除此之外,它不受(良好或广泛)支持。
