opcache

Reading various guides for installing nextcloud led me to https://www.sharpwriting.net/project/nextcloud-on-freebsd/ where in the section on configuring php

4. Configure php.ini​


there is the following section which I haven't seen in any other guide. I have no idea about opcache and am wondering whether it gives me anything.

Code: 
[opcache]
zend_extension=opcache
opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=512
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.revalidate_freq=1
opcache.save_comments=1
 
OPCache caused me grief with mod_php, but I think you are using php_fpm.

Thread 'apachectl graceful causes SIGSEGV with latest PHP 8.1.x and PHP 8.2.x'

Wondering if anyone else seeing this?

Building from ports (just because that's what I've always done) - FreeBSD 13.1 (or 13.2) on amd64, Apache 2.4.56 or 2.4.57, PHP 8.2.4 (and 8.2.5) both exhibit the behaviour, as do 8.1.17 and 8.1.18.

mod_php82 (or 81).

Noticed when logs rotated, but further digging showing it's effectively the apachectl graceful causing my problems. After an apachectl graceful you'll have stopped serving web pages. apachectl restart is fine.

Apache and mod_php82 were fine, so I started adding a few extensions and got it to start happening. Thought it was cURL for...

Looks like it might have eventually been resolved:


YMMV.

Not sure if opcache differs when used with nginx, but I never changed an opcache setting aside just enabling the module (it sped up pages all OSs default settings). Some recent PHP 8 release I think integrates opcache ( zend_extension = "opcache" on Windows started throwing a warning but removing that still had it loaded)

opcache.memory_consumption might be interesting though; 512 seems fine for me (several sites with individual php-fpm and 16G RAM), but I'd consider upping that if you have the resources.

https://www.php.net/manual/en/opcache.configuration.php mentions opcache.jit being disabled 8.4+ (not sure why; seems better enabled but I have more settings to look into now :p)
