Opcache loaded twice

[dkarlovi]

$ docker run --rm jakzal/phpqa:1.111.0-php8.4-alpine php -v
Cannot load Zend OPcache - it was already loaded
PHP 8.4.8 (cli) (built: Jun 25 2025 19:14:13) (NTS)
Copyright (c) The PHP Group
Built by https://github.com/docker-library/php
Zend Engine v4.4.8, Copyright (c) Zend Technologies
    with Zend OPcache v8.4.8, Copyright (c), by Zend Technologies

Looking at the config, two separate files are trying to load the ext:

/usr/local/etc/php/conf.d/docker-php-ext-opcache.ini
/usr/local/etc/php/conf.d/opcache.ini

I'm not sure which one is the correct one.

Note that you can also see this issue in the build itself, we should probably add a smoke test to avoid this in the future.

I guess this is also related to this @dkarlovi?

Probably, yes.

@aziyan99 if this is a blocker for you too, do you plan to work on a fix? It's not just an annoyance in our case because it actually crashes Infection which detects it like PHPUnit complaining and thus sees it as "PHPUnit failed to run".

[jakzal]

Looks like opcache is now enabled by default and we don't need to enable it explicitly anymore: docker-library/php#1587

@dkarlovi not sure how to write a smoke test, since the message is only sent to the output without an indication it's a warning or an error

It's dumb, but we can just test if stderr contains a substring of PHP warning about this? It will always do it in the same way so it's close enough, better than nothing.

[jakzal]

I'll take my chances and do nothing ;)

Thanks, @dkarlovi @aziyan99 for reporting this.

I'll make a new release soon.
