#28589: Segfault in Reflection API

- Don't allow passing NULL to type hinted parameter.

- Fixed bug #27923. foreach() without a key should not check if the key
- is a reference (Adam)

Restore fatal error in case a method that's supposed to implement an
interface/abstract method, breaks its prototype

Force destructors to have empty signatures

- If __construct() is defined then it will always take precedence over
- old style constructors.

- Fix bug

- Change redefinition of constructor from E_COMPILE_ERROR to E_STRICT.

fix typo

Add ability to disable JIT for a particular auto global

- Fix problem when using old-style constructors it wasn't being inherited
correctly.

Clearify the different method/class flags (as discussed with Andi).

- Nuke unused code.

- Fix some small problems I introduce in last patch.

- Finally fix the following:
$xml_mem = simplexml_load_string('<bookbody><part><chapter><page>1</page></chapter></part></bookbody>');
/* The following works fine */
foreach ($xml_mem->par

- Finally fix the following:
$xml_mem = simplexml_load_string('<bookbody><part><chapter><page>1</page></chapter></part></bookbody>');
/* The following works fine */
foreach ($xml_mem->part as $part) {
foreach($part->chapter->page as $page) {
print $page;
}
}
/* The following segfaults */
foreach ($xml_mem->part as $part) {
foreach($part->chapter as $chapter) { // Difference here from previous example
print $chapter;
}
}

Disallow redefining ctors and cleanup

- Fix leaks (although there might be still a problem here).

- Fix crash in:
<?php
class Foo {
public $attributes= array();

function export() {
foreach ($this->attributes as $name => $attr) {
}
}

- Fix crash in:
<?php
class Foo {
public $attributes= array();

function export() {
foreach ($this->attributes as $name => $attr) {
}
}
}

$f= new Foo();
$f->export();
?>

- Change prototype isA check not to check the constructor.
- Only give an E_STRICT for non-isA compliant code as opposed to
E_COMPILE_ERROR.

Fixes for abstract classes/methods

Fix leak in foreach ($o->mthd()->arr)

- Improve ARG_INFO() macros to support supplying required_num_args
- Initial fix for foreach($o->mthd()->arr) crash (now leaks)

- Rename compatiblity mode to zend.ze2_compatibility_mode (it doesn't only affect auto-clone).
- Perform implementation checks even with simple inheritance (off when
compatibility mode is

- Rename compatiblity mode to zend.ze2_compatibility_mode (it doesn't only affect auto-clone).
- Perform implementation checks even with simple inheritance (off when
compatibility mode is enabled).
- Restore default arguments in interfaces and handle it correctly.
- Move registration of internal classes later in the startup sequence
in order to have INI options available.
