Bug description: Custom dir_readdir() causes readdir() to crash when returns
false
Description:
------------
dir_readdir seems to cause a crash when used with readdir(). Code below is
based on the \ext\standard\tests\file\userdirstream.phpt test, but instead
of using scandir() which appears to work fine, the manual looping causes
an application exception.
Reproduce code:
---------------
class test {
public $idx = 0;
function dir_opendir($path, $options) {
print "Opening\n";
$this->idx = 0;
return true;
}
function dir_readdir() {
$sample = array('first','second','third','fourth');
if ($this->idx >= count($sample))
return false;
else
return $sample[$this->idx++];
}
function dir_rewinddir() {
$this->idx = 0;
return true;
}
function dir_closedir() {
print "Closing up!\n";
return true;
}
}
stream_wrapper_register('test', 'test');
$dh = opendir('test://example.com/path/to/test');
if ($dh) {
while (($f = readdir($dh)) !== FALSE)
echo $f, "\n";
}
Expected result:
----------------
Opening
first
second
third
fourth
without an application exception
Actual result:
--------------
Opening
first
second
third
fourth
with an application exception
