[2.1]: fetch_web_data() - sockets fails, cURL not attempted

[sbulen]

Basic Information

I ran into this testing a mod, so it's not strictly an SMF error, but I figured I'd log it for awareness, as it suggests fetch_web_data might need a tweak.

If sockets fails after the socket is open, e.g., on this line:

SMF/Sources/Subs.php

Line 6185 in 9ab8bff

fwrite($fp, 'Host: ' . $match[3] . (empty($match[5]) ? ($match[2] ? ':443' : '') : ':' . $match[5]) . "\r\n");

...cURL is never attempted. I have run into several URLs where sockets fails there, but cURL works. Sockets seems to fail for ~15% of test URLs. Using cURL always works, so I am no longer using fetch_web_data at all, and directly using cURL instead.

I think it should realize fetch_web_data() isn't getting anywhere & move on to cURL...

Note the failure is with this message: "2: fwrite(): SSL: An established connection was aborted by the software in your host machine"

I'll be honest, l couldn't figure out how to get past that issue. Some of the materials I found suggested this is a CORS issue. In fact, I tried configuring CORS for these sites, and while it got further along, it still failed with the same message, just on a different line.

I don't know if 3.0 is affected also.

Steps to reproduce

1. Sample url: https://sfpublicpress.org/news/feed

Expected result

I thought that if sockets failed, curl would be used

Actual result

curl was not attempted
