Description

Hey!

I think I tracked a PHPRedis issue where it very sporadically throws a "Operation is in progress" exception on connect to a bug in the php_network_connect_socket() function. The problem is that it doesn't clear an earlier occurring EINPROGRESS error, which will then get returned while it checks for select() errors.

https://github.com/php/php-src/pull/13252 for a possible fix.

Regards,
Maurits

Research direction

Start by reading the php_network_connect_socket() implementation and the proposed fix in PR 13252. Reproduce the synchronous connection case described for PHP 8.3.1 on Ubuntu 20.04, then verify that a successful connection no longer reports an "Operation is in progress" exception.
