Bug description:Bogus behavior of Zend in relation to stream wrappers
Description:
------------
See test script: when returning a undefined key from stream_stat(), the
behavior
of the Zend interpretor changes.
I confirmed this on PHP 5.3.5, pjoye reproduced it separately.
Test script:
---------------
--TEST--
Test that user space streams do not break the fabric of the universe.
--FILE--
<?php
class UserSpaceStream {
public function stream_open($uri, $mode, $options, &$opened_path) {
return TRUE;
}
public function stream_read($count) {
return '';
}
public function stream_write($data) {
return TRUE;
}
public function stream_eof() {
return FALSE;
}
public function stream_stat() {
$stat = array();
// This triggers (correctly) a "Notice: Undefined index: size in %s on
line %d".
$array = array();
$stat['size'] = $array['size'];
return $stat;
}
}
stream_wrapper_register("test", "UserSpaceStream");
// Alone, the assignment of a key to an undefined variable is legal.
$undefined_variable['key'] = 'value';
// This fstat() call triggers something weird...
$h = fopen('test://anyfile', 'r');
fstat($h);
// ... from this point, PHP triggers a "Warning: Cannot use a scalar value
as
// an array" for each assignement of array keys to undefined variables.
$undefined_variable2['key'] = 'value';
?>
--EXPECTF--
Notice: Undefined index: size in %s on line %d
