Bug #70208 [NEW]: Assert breaking access on objects
From: neclimdul at gmail dot com
Operating system: linux
PHP version: 7.0Git-2015-08-07 (Git)
Package: Class/Object related
Bug Type: Bug
Bug description:Assert breaking access on objects
Description:
------------
Recently some code adding assertions to code in Drupal caused some
really weird failures when running tests. It seems you need a couple
things to trigger this.
1) You have an object stored on a property
2) You call an assert that calls a method on an argument.
3) You reference the protected property after that assertion.
Test script:
---------------
<?php
class class1 {
protected $prop;
public function __construct($prop) { $this->prop = $prop; }
public function getThing($arg) {
assert('$arg->isValid();');
$this->prop->method();
}
}
class class2 {
public function method() { echo "here\n"; }
}
class class3 {
public function isValid() { return false; }
}
$tmp = new class1(new class2());
$tmp->getThing(new class3());
Expected result:
----------------
the script outputs "here"
Actual result:
--------------
PHP Fatal error: Uncaught Error: Cannot access protected property
class1::$prop in
/home/jgilliland/public_html/d8_1/assert_protected_property.txt:8
Stack trace:
#0 /home/jgilliland/public_html/d8_1/assert_protected_property.txt(21):

#1 {main}
