从gevent-subprocess获取实时标准输出? [英] Get live stdout from gevent-subprocess?

问题描述

我正在尝试通过POPEN获得进程的标准输出. 使用gevent 1.0，readline()和read()仍会阻塞进程并等待进程完成. 有什么线索吗?是的，我在高端和低端搜索了一个简单的解决方案.必须没有线程，对吧?

I'm trying to get the stdout of a process via POPEN as soon as it's there. With gevent 1.0 readline() and read() still block process and wait for process to finish. Any clues? And yes, I searched high and low for a simple solution. It has to be possible without threading, right?

推荐答案

我用一点技巧解决了这个问题.每当将一行写入标准输出时，只需刷新带有self.stream.flush()的Python行缓冲区和一个帮助器类即可.

I solved this using a little hack. Just flush Pythons line-buffer w/ self.stream.flush() and a helper class whenever a line is written to stdout.
