Previous Comments: ------------------------------------------------------------------------ [2019-12-11 00:34:31] hopeseekr at gmail dot com I would have guessed someone would have run Laravel's phpunit test suite while and after developing something as inner-touching as preloading. Guess not! Probably didn't run Symonfy's tests either. ------------------------------------------------------------------------ [2019-12-10 13:19:45] cmb@php.net > You will not get a fatal error […] That is supposed to be "You will now get a fatal error […]". ------------------------------------------------------------------------ [2019-12-10 12:59:02] nikic@php.net Support for class aliases has been added, and issues relating to classes with unresolved initializers fixed. You will not get a fatal error if you try to preload a class with unresolved initializers under the "require" model (under the opcache_compile_file() model a graceful fallback is possible). However, opcache will try harder to make sure everything can be resolved. I was not able to test preloading Laravel due to https://github.com/briannesbitt/Carbon/blob/298d9f0e8e369301b0ca647f3ce9c92b53ad3a82/src/Carbon/Traits/Date.php#L541-L556. This references constants that are not defined in the trait and are only available in the class using the trait. This will need to either be fixed, or the trait and it's dependencies skipped. ------------------------------------------------------------------------ [2019-12-10 10:40:10] fosron at gmail dot com I've tested preloading Laravel too, and i'm getting "zend_mm_heap corrupted" with this script (https://github.com/brendt/laravel-preload/blob/master/preload.php) on a Docker container (both require and opcache_compile_file options don't work). ------------------------------------------------------------------------ [2019-12-09 17:05:09] themohamedsaid at gmail dot com Unfortunately I keep getting a segfault even when switching to opcache_compile_file() and restarting php-fpm.
