Bug #78225 [Opn]: Preloading Laravel results in a segfault

Edit report at https://bugs.php.net/bug.php?id=78225&edit=1 ID: 78225 Updated by: nikic@php.net Reported by: brent at spatie dot be Summary: Preloading Laravel results in a segfault Status: Open Type: Bug Package: opcache Operating System: macOS Mojave PHP Version: 7.4.0alpha2 Block user comment: N Private report: N New Comment: I've pushed some improved diagnostics for the unlinked class messages. You'll now see something like: Warning: Can't preload unlinked class Illuminate\Http\Exceptions\PostTooLargeException: Unknown parent Symfony\Component\HttpKernel\Exception\HttpException in /home/nikic/laravel-preload/vendor/laravel/framework/src/Illuminate/Http/Exceptions/PostTooLargeException.php on line 8 Which should make it clear that the reason why you're not seeing much preloading is that you are only preloading Laravel, without its Symfony component dependencies.

It turns out the segfault only happens when trying to preload one of these classes: - \Illuminate\Log\LogManager (https://github.com/laravel/framework/blob/5.8/src/Illuminate/Log/LogManager.php) - \Illuminate\Http\Testing\File (https://github.com/laravel/framework/blob/5.8/src/Illuminate/Http/Testing/File.php) - \Illuminate\Http\UploadedFile (https://github.com/laravel/framework/blob/5.8/src/Illuminate/Http/UploadedFile.php) - \Illuminate\Support\Carbon (https://github.com/laravel/framework/blob/5.8/src/Illuminate/Support/Carbon.php) I've also updated my example project: https://github.com/brendt/laravel-preload/commit/fa8e8b253ebd771f99c41554ed44b80197a23ba7 ------------------------------------------------------------------------ [2019-07-02 11:57:16] facades at laravel dot com The following patch has been added/updated: Patch Name: did_you_try_adding_facades_prefix Revision: 1562068636 URL: https://bugs.php.net/patch-display.php?bug=78225&patch=did_you_try_adding_facades_prefix&revision=1562068636 ------------------------------------------------------------------------ [2019-07-01 08:23:39] brent at spatie dot be I added a version using opcache_compile: https://github.com/brendt/laravel-preload/tree/opcache_compile ; it also results in a segfault. The reason I wanted to use include or require is that it opcache_compile seemed to result in lots of unlinked classes. My guess was this it wouldn't resolve the class dependencies since the docs explicitly state that it won't execute the file. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
