Bug #74576 [NEW]: opcache do not update class constant after uopz_redefine
From: kejinjin at gmail dot com
Operating system: CentOS7x64
PHP version: 7.1.5
Package: opcache
Bug Type: Bug
Bug description:opcache do not update class constant after uopz_redefine
Description:
------------
I use uopz_redefine to redefine class constants
(uopz called zend_declare_class_constant)
when opcache is enabled, I cannot get the new class constant through
Foo::BAR.
Test script:
---------------
<?php
class Foo
{
const BAR = '123';
}
var_dump(Foo::BAR);// A1: try to comment this
(function () {
var_dump(Foo::BAR); // B1: try to comment this
uopz_redefine('Foo', 'BAR', '456');
var_dump(Foo::BAR); // B2: compare
})();
(function () {
var_dump(Foo::BAR); // new scope
})();
var_dump((new ReflectionClass('Foo'))->getConstant('BAR')); // also OK
var_dump(Foo::BAR); // A2: compare
Expected result:
----------------
'123'
'123'
'456'
'456'
'456'
'456'
Actual result:
--------------
'123'
'123'
'123' (it is '456' if line B1 is commented)
'456'
'456'
'123' (it is '456' if line A1 is commented)
