Edit report at https://bugs.php.net/bug.php?id=80322&edit=1 ID: 80322 Comment by: ricardo dot cescon at panthermedia dot net Reported by: sametsahindogan at gmail dot com Summary: Preloader does not work as expected Status: Open Type: Bug Package: opcache Operating System: Ubuntu 20.04.1 LTS PHP Version: 7.4.12 Block user comment: N Private report: N New Comment: in addition to my last comments: removing "php7.4-uopz" solve all our problems with opcache Previous Comments: ------------------------------------------------------------------------ [2020-11-12 14:41:02] ricardo dot cescon at panthermedia dot net We also see another problem with enabled opcache: traits not will be used correctly. Error: Call to undefined method XYZ::do_something() Sample: ################################ trait tX{ protected function do_something(){ } } //--------- abstract class Y extends Z{ use tX; } //--------- class XYZ extends Y{ function __construct(){ $this->do_something(); } } ################################ Version PHP 7.3.24 work as expected ------------------------------------------------------------------------ [2020-11-12 12:13:13] ricardo dot cescon at panthermedia dot net We have currently a similar problem switching to PHP version 7.4.12, but without Laravel and on Ubuntu 18.04.5 LTS. We get the following error with enabled opcache: Call to undefined method SphinxClient::SetServer() This occurs on the following of code sample ############################################ class sphinxAPI extends SphinxClient { ... function SetServer($host, $port = null) { ... parent::SetServer($this->_servers[0][0], $this->_servers[0][1]); ... ############################################ with opcache.enable = Off everything works as expacted PHP 7.3.24 also work as expacted ------------------------------------------------------------------------ [2020-11-06 16:54:16] jon dot johnson at ucsf dot edu This may be the same as reported in https://github.com/symfony/symfony/issues/39010 where ArgumentCountError: Too few arguments to function Symfony\Component\Cache\Adapter\AbstractAdapter::throwError(), 2 passed in and exactly 4 expected is thrown when pre-loading is enabled. I wasn't able to distill this to a PHP script case, but using symfony I created a docker based reproduction of this at https://github.com/jrjohnson/reproduction-symfony-error-apc-opcache the error can be reproduced there by doing: composer install docker-compose build docker-compose up Then visit http://127.0.0.1:8000/ which will fail with a 500 error and messages logged to the console running docker-compose. ------------------------------------------------------------------------ [2020-11-06 10:31:59] nikic@php.net There's been quite a few reports of preloading issues with this release. I believe the problem has been introduced by https://github.com/php/php-src/commit/3928b6b435f6c7c818e8211b2ecdeeb7191310d1 (this commit by itself is correct, but it exposed a pre-existing issue) and will be fixed by https://github.com/php/php-src/commit/6808968c896a18d2b9f309b2fe63d529058b78b4 (in 7.4.13). If you are able to test current PHP-7.4 HEAD, it would be great to confirm the issue is indeed resolved. ------------------------------------------------------------------------ [2020-11-05 21:29:43] sametsahindogan at gmail dot com Btw I guess I must say again, I haven't made any changes to the code. (I also didn't change the Laravel version.) Everything was working fine with the preload. I just updated to PHP 7.4.12 and these errors occurred. I don't think there is a problem with the application layer. I have tested it on other different servers (with clean PHP 7.4.12 and Laravel installation) as I thought it might be a different problem, but the error persists. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
