php pthreads 不会在 xampp 7.0.2 上启动 [英] php pthreads won't launch on xampp 7.0.2

问题描述

我已经安装了新的 xampp (7.0.2 atm).我已经创建了 php-cli.ini，在那里添加了 pthread 扩展并将内存限制设置为 3 GB.但是当我尝试启动线程脚本时，我得到了这个:

I have installed fresh xampp (7.0.2 atm). I've created php-cli.ini, added pthread extension there and set memory limit to 3 gb. But when I'am trying to launch thread script I got this:

PHP Fatal error:  Uncaught RuntimeException: cannot start my_thread, out of reso
urces in C:\xampp\htdocs\w\start_threads.php:160
Stack trace:

推荐答案

本质上是pthread_create返回EAGAIN造成的:表示系统缺少资源来创建另一个线程，或者系统对线程的最大数量(在一个进程中，或系统范围内)施加了限制.

Essentially, this is caused by pthread_create returning EAGAIN: It means that the system lacks resources to create another thread, or that the system imposed limit on the maximum number of threads (in a process, or system wide) has been reached.

这可能是由两件事引起的，由于某些软件的设计方式，故意使用比进程可以同时处理的线程更多的线程，或者更有害的是，由于线程的连接不够优雅.

This can be caused by two things, the purposeful use of more threads than a process can handle simultaneously as a result of the way some software is designed, or more perniciously, as a result of less than graceful joining of threads.

如果您似乎只是有时会遇到此类错误，则表明后者正在发生；请务必清理(显式连接)您已完成的线程，以使行为可预测.

If you only seem to hit such errors sometimes, it would suggest the latter is going on; Be sure to cleanup (explicitly join) threads you are done with to make behaviour predictable.
