Bug #79440 [Opn]: Object typehint sometimes seems to be misunderstood

Edit report at https://bugs.php.net/bug.php?id=79440&edit=1 ID: 79440 User updated by: lmprogg at gmail dot com Reported by: lmprogg at gmail dot com Summary: Object typehint sometimes seems to be misunderstood Status: Open Type: Bug Package: Class/Object related Operating System: Ubuntu PHP Version: 7.3.16 Block user comment: N Private report: N New Comment: I am sorry, seems that the tests are run with a different version. Could have saved the effort creating this. Late hour. If I double checked that is indeed not only outputting 7.3.16 for the version but actually using it, I'll report back ... :/ Previous Comments: ------------------------------------------------------------------------ [2020-03-31 22:18:50] lmprogg at gmail dot com Description: ------------ It is difficult for me to make this reproducible. Short notice on the setup: A local vm with vagrant and php 7.3.16: PHP 7.3.16-1+ubuntu16.04.1+deb.sury.org+1 (cli) (built: Mar 20 2020 13:51:21) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.16, Copyright (c) 1998-2018 Zend Technologies with Zend OPcache v7.3.16-1+ubuntu16.04.1+deb.sury.org+1, Copyright (c) 1999-2018, by Zend Technologies That one does *not* have the problem. Then there is an aws instance that is running the following version: PHP 7.3.16-1+ubuntu18.04.1+deb.sury.org+1 (cli) (built: Mar 20 2020 13:51:46) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.16, Copyright (c) 1998-2018 Zend Technologies with Zend OPcache v7.3.16-1+ubuntu18.04.1+deb.sury.org+1, Copyright (c) 1999-2018, by Zend Technologies This one *has* the problem. The following happens (I also included a little code snippet, although it may be hard to reproduce). Whenever a typehint "object" is encountered (in my failing case, it is PHPUnit, but it happens on any typehint "object", even in other functions): [TypeError] Argument 5 passed to PHPUnit\Framework\MockObject\Invocation::__construct() must be an instance of PHPUnit\Framework\MockObject\object, instance of Mock_MyClient_070b46a8 given, called in /project/vendor/phpunit/phpunit/src/Framework/MockObject/MockClass.php(42) : eval()'d code on line 47 This is the line that does not pass the typecheck: (PHPUnit 9.0.2) public function __construct(string $className, string $methodName, array $parameters, string $returnType, object $object, bool $cloneObjects = false, bool $proxiedCall = false) The 5th parameter seems to be misunderstood to be an "object" of the same namespace, instead of the reserved "object" keyword. (which should be passed by the mock passed in) I first had this in 7.3.9, and then upgraded to the latest 7.3.16, but the problem still persisted on the AWS instance. I am not sure if this is a bug or just a configuration issue, but it seems that some versions (I am not sure how they differ) are unable to understand this relatively new typehint which was introduced in php 7.2. I included a little snippet that *might* reproduce it. If you need more info, please tell me, it is just a little hard to get it from the aws instance (which is why I did not go haywire and collected everything beforehand). The code in the snippet should actually just produce a failure because of different contents that are compared, but throws this on the aws instance: [TypeError] Argument 1 passed to Test\Namespace1\MyTest::getMyResult() must be an instance of Test\Namespace1\object, instance of stdClass given, called in /project/tests/Test/Namespace1/MyTest.php on line 14 (The line number might differ) I hope someone might have an idea how this can fit together and guide me in the right direction. Happy to assist with further input. Good night!
