Bug #79055 [Opn->Ver]: Typed property become unknown with OPcache file cache

Edit report at https://bugs.php.net/bug.php?id=79055&edit=1 ID: 79055 Updated by: nikic@php.net Reported by: kentaro at ranvis dot com Summary: Typed property become unknown with OPcache file cache -Status: Open +Status: Verified Type: Bug Package: opcache Operating System: Linux PHP Version: 7.4Git-2020-01-02 (Git) Block user comment: N Private report: N New Comment: Also seeing some serious map_ptr issues when mixing file_cache and shm. Previous Comments: ------------------------------------------------------------------------ [2020-01-02 10:01:57] kentaro at ranvis dot com Description: ------------ When OPcache loads cached script from file, PHP fails to identify typed property specifier in the loaded class, and reports it typed as "unknown or null". Fails on PHP-7.4 (8d2b20db58849d1f54303f66656a3776456cbe95), while succeeds on master (a9c04aee67a1d787101c967b8980d679b1714bf0). I'm sorry to bother if it's going to be fixed in 7.4 branch too. Test script: --------------- mkdir /dev/shm/opcache ./php -n -d extension_dir=modules/ -d zend_extension=opcache -d opcache.enable=1 -d opcache.enable_cli=1 -d opcache.file_cache=/dev/shm/opcache main.php # run above script twice [main.php] <?php opcache_reset(); spl_autoload_register(function ($cls) { echo "$cls\n"; require_once(__DIR__ . "/$cls.php"); }); try { $c = new C(); $x = new X($c); echo "Success\n"; } catch (Error $e) { echo $e->getMessage() . "\n"; } [C.php] <?php class C {} [X.php] <?php class X { private C $c; public function __construct(C $c) { $this->c = $c; } } Expected result: ---------------- $ ./php ... C X Success $ ./php ... C X Success Actual result: -------------- $ ./php ... C X Success $ ./php ... C X Typed property X::$c must be unknown or null, C used ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79055&edit=1
