Log: - Fixed bug #54384 (Dual iterators, GlobIterator, SplFileObject and
SplTempFileObject crash when user-space classes don't call the paren
constructor).

Revision: http://svn.php.net/viewvc/?view=revision&revision=309751
Log: - Improved upon r309729.
- Extented strategy to remaining the classes on spl_directory.c, even
those that don't crash.
- UPGRADING.
- Better bug54384.phpt, with all the classes covered.

Log: - Fixed bug #54384: Several SPL classes crash when parent
constructor is
not called.
#Merge to 5.3 pending (slight BC break on AppendIterator, as it's no
#longer possible to defer the call to the parent constructor until
#after the constructor is performed).
#Bugs fixed in an atypical way for SPL. The parent constructor call
#check is performed at construction time by using a wrapper constructor
#instead of a check on the beginning of each instance method.
#Perhaps this should be uniformized in trunk; this method was mainly
#applied only to the ones crashing, except a few iterators (at least
#AppendIterator and RecursiveIteratorIterator).

I wondered if other classes are be affected by this, and after some
tests I found that the following classes are affected:
IteratorIterator
FilterIterator
RecursiveFilterIterator
ParentIterator
LimitIterator
CachingIterator
RecursiveCachingIterator
NoRewindIterator
InfiniteIterator
RegexIterator
RecursiveRegexIterator
GlobIterator
SplFileObject
SplTempFileObject
tests:
<?php
class IteratorIteratorTest extends IteratorIterator {
function __construct(){}
}
$o = new IteratorIteratorTest;
$o->rewind()
class FilterIteratorTest extends FilterIterator {
function __construct(){}
function accept(){}
}
$o = new FilterIteratorTest;
$o->rewind()
class RecursiveFilterIteratorTest extends RecursiveFilterIterator {
function __construct(){}
function accept(){}
}
$o = new RecursiveFilterIteratorTest;
$o->hasChildren()
class ParentIteratorTest extends ParentIterator {
function __construct(){}
}
$o = new ParentIteratorTest;
$o->accept()
class LimitIteratorTest extends LimitIterator {
function __construct(){}
}
$o = new LimitIteratorTest;
$o->rewind()
class CachingIteratorTest extends CachingIterator {
function __construct(){}
}
$o = new CachingIteratorTest;
$o->rewind()
class RecursiveCachingIteratorTest extends RecursiveCachingIterator {
function __construct(){}
}
$o = new RecursiveCachingIteratorTest;
$o->rewind()
class NoRewindIteratorTest extends NoRewindIterator {
function __construct(){}
}
$o = new NoRewindIteratorTest;
$o->valid()
class InfiniteIteratorTest extends InfiniteIterator {
function __construct(){}
}
$o = new InfiniteIteratorTest;
$o->next()
class RegexIteratorTest extends RegexIterator {
function __construct(){}
}
$o = new RegexIteratorTest;
$o->rewind()
class RecursiveRegexIteratorTest extends RecursiveRegexIterator {
function __construct(){}
}
$o = new RecursiveRegexIteratorTest;
$o->hasChildren()
class GlobIteratorTest extends GlobIterator {
function __construct(){}
}
$o = new GlobIteratorTest;
$o->count()
class SplFileObjectTest extends SplFileObject {
function __construct(){}
}
$o = new SplFileObjectTest;
$o->rewind()
class SplTempFileObjectTest extends SplTempFileObject {
function __construct(){}
}
$o = new SplTempFileObjectTest;
$o->rewind()

Description:
------------
FilterIterator instances crash when the constructor has not been called
(accidentally).
Test script:
---------------
<?php
class Test extends FilterIterator {
function __construct() {
}
function accept() {
}
}
$t = new Test;
foreach($t as $e);
