Edit report at https://bugs.php.net/bug.php?id=78106&edit=1 ID: 78106 Comment by: martijn at squeezely dot tech Reported by: mbiebl at messageconcept dot com Summary: PHP Fatal error: Uncaught Error: Class 'Phpfastcache\Config\Config' not found Status: Assigned Type: Bug Package: opcache Operating System: Windows Server 2016 / IIS 10 PHP Version: 7.2.19 Assigned To: dmitry Block user comment: N Private report: N New Comment: We managed to find a way to reproduce. We use nginx + php-fpm 7.2.19 with the patch supplied from dmitry@php.net Step to reproduce Create the following files: test.php ---------- <?php ini_set('opcache.enable', 0); require_once 'include.php'; echo 'done'; ---------- test2.php ---------- <?php require_once 'include.php'; echo 'done'; ---------- include.php ---------- <?php echo 'included'; ---------- 1. Request test.php 2. Request test2.php 3. Request test.php Final test.php request will break. We also tried this with require instead of require_once but this did NOT break. Hope this helps you fix this bug. If we need to retest with a certain patch in place let me know. Previous Comments: ------------------------------------------------------------------------ [2019-06-12 15:18:28] mbiebl at messageconcept dot com I've changed my php.ini to enable debug logging for opcache like this: ``` zend_extension=php_opcache.dll opcache.enable_cli=1 opcache.enable=1 opcache.error_log="C:\Windows\temp\php_opcache.log" opcache.log_verbosity_level=4 ``` Unfortunately, this didn't produce any useful log messages. I only get messages like this: ``` Wed Jun 12 17:11:38 2019 (4748): Message Cached script 'C:\src\server\localhost\vendor\psr\log\Psr\Log\LoggerInterface.php' Wed Jun 12 17:11:38 2019 (4748): Message Added key 'C:\src\server\localhost\vendor\composer/../psr/log/Psr/Log\LoggerInterface.php' ``` Also, this is only for one php process (4748), while I have multiple processes. ------------------------------------------------------------------------ [2019-06-11 20:24:38] nikic@php.net @mbiebl at messageconcept dot com: Assuming you already have opcache.error_log configured, if you set opcache.log_verbosity_level=4 it will capture all log messages. Maybe a lower level is enough to log non-user restarts, but I'm not sure. ------------------------------------------------------------------------ [2019-06-11 19:59:24] mbiebl at messageconcept dot com How can I find out if there was an opcache restart? Is there a way to get a more verbose debug log from the opcache module? ------------------------------------------------------------------------ [2019-06-11 13:28:31] nikic@php.net Thanks for the information! If this issue only occurs sporadically, is there any correlation with opcache restarts? That is, does the error occur around the same time that an opcache restart even occurs? ------------------------------------------------------------------------ [2019-06-11 13:26:42] dmitry@php.net May be this patch can help https://gist.github.com/dstogov/b13163408e0edf337b99b4e634cba38f But it's really hard to guess, without a way to reproduce the problem. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
