Avatar upload error

sergyu91ma

Hello,
I have this error when i try to upload an avatar image.
I`m using dev-master branch version because i have php 7.4 and the beta doesnt work yet on 7.4.
I see no errors in log on backend.

sergyu91ma can you find any error in your webserver logs ? It looks like the request failed at the webserver level even before Flarum can start handling the request.

Also running Flarum dev-master really comes at your own risks. We have no way of guaranteeing support. Best to downgrade to PHP 7.3 for beta 11 or wait for beta 12 to be officially released.

clarkwinkelmann i attached lldb to apache to see why it crashes, because it`s a crash in PHP. This is backtrace:

sergyu91ma I'm not sure what I can do with that information 😬

My only suggestion for now would be to run beta 11 on PHP 7.3 and see if you have the same issue.

sergyu91ma

clarkwinkelmann Now that beta 12 has been released (i upgraded to beta 12) i have the same problem. IDK if it's a bug in PHP or flarum though. I cannot upload any kind of image/file. I get this every time when i try.

sergyu91ma Can you pull the actual error/access logs from your webserver (in debian/ubuntu it would be located somewhere inside /var/log/) please ensure you remove private/sensitive information

I'm actually on:
FreeBSD yonan 12.1-STABLE FreeBSD 12.1-STABLE r355126 GENERIC amd64.
PHP 7.4.3 (cli) (built: Feb 28 2020 15:24:39) ( ZTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
with Zend OPcache v7.4.3, Copyright (c), by Zend Technologies

This is what i get in error log when i try to upload any file:

It's actually a PHP crash. I attached lldb to apache to see what is happening.
You have the stack trace in this conversation in an earlier reply.

Thanks.

Can you try to recompile your PHP and see if that solve anything ? FreeBSD is kinda special in his way of doing things.
Also, how are you pluging your webserver to php ? Can you try via php-fpm ?

sergyu91ma

I've recompiled mod_php74 but still same thing. I'm using Server API Apache 2.0 Handler.
I'll try with php-fpm.
This is a weird bug of PHP i think.
Thanks.

sergyu91ma

with PHP-fpm works fine. Weird. It could be a bug in mod_php.
