Bug #72373 [NEW]: TypeError after Generator function w/declared return type finishes
From: michael dot moussa at gmail dot com
Operating system: linux (CentOS 7)
PHP version: 7.1.0alpha1
Package: Scripting Engine problem
Bug Type: Bug
Bug description:TypeError after Generator function w/declared return type finishes
Description:
------------
The provided Test Script produces the Expected Result in 7.0.7, but
encounters a TypeError in 7.1.0alpha1. The issue seems to have been
introduced by the removal of the ZEND_VERIFY_RETURN_TYPE case in this
commit:
https://github.com/php/php-src/commit/cb3825a8dc551e6a43b4ea3a01dbd0584bf606bb#diff-8f41738bb0ceb7bf7c9882a4b399ab6eL645.
Removing the Generator return type declaration or adding an empty return
statement after the final yield seems to function as a workaround, but
naturally I'd prefer to change nothing if this break was an
unintentional.
Test script:
---------------
<?php
function foo() : Generator
{
yield 1;
yield 2;
yield 3;
}
foreach (foo() as $bar) {
echo $bar . "\n";
}
Expected result:
----------------
1
2
3
Actual result:
--------------
1
2
3
Fatal error: Uncaught TypeError: Return value of foo() must be an
instance of Generator, none returned in /tmp/foo.php:8
Stack trace:
#0 /tmp/foo.php(10): foo()
#1 {main}
thrown in /tmp/foo.php on line 8
