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: @brent: That one is likely a bug on our side, I'll take a look. Previous Comments: ------------------------------------------------------------------------ [2019-07-03 12:51:36] brent at spatie dot be Thanks Nikita, the improved logging helps indeed. Could you tell me what the correct approach would be in this case? ``` Can't preload unlinked class Ramsey\Uuid\Exception\UnsupportedOperationException: Parent with unresolved property types RuntimeException in ``` It turns out that this specific class extends \RuntimeException like so: ``` class UnsupportedOperationException extends \RuntimeException ``` How would you go about preloading built-in classes? Shouldn't this happen automatically? ------------------------------------------------------------------------ [2019-07-03 12:07:18] nikic@php.net 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. ------------------------------------------------------------------------ [2019-07-03 11:45:04] nikic@php.net I can't reproduce this crash on current 7.4 head. ------------------------------------------------------------------------ [2019-07-02 12:49:30] brent at spatie dot be Edit because of autofiller changing the summary ------------------------------------------------------------------------ [2019-07-02 12:48:43] brent at spatie dot be I'm not sure whether the patch about facades was a troll or not, but it gave me a debug idea. 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 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
