2bbf4ad261 Bugfix #24637 __destruct not called 2003-08-10 23:59:35 +00:00
Moriyoshi Koizumi
fe489dcb4f Fix segfault when a referenced parameter is specified with typehint. 
Result of the node will never be used because verify_instanceof handler has
been eliminated.

f8bbafd604 ntroduce infrastructure for supplying information about arguments, 
including:

- Whether or not to pass by ref (replaces the old arg_types, with arg_info)
- Argument name (for future use, maybe introspection)
- Class/Interface name (for type hints)
- If a class/interface name is available, whether to allow a null instance

Both user and builtin functions share the same data structures.

To declare a builtin function that expects its first arg to be an instance
of class 'Person', its second argument as a regular arg, and its third by
reference, use:

ZEND_BEGIN_ARG_INFO(my_func_arg_info, 0)
    ZEND_ARG_OBJ_INFO(0, someone, Person, 1)
    ZEND_ARG_PASS_INFO(0)
    ZEND_ARG_PASS_INFO(1)
ZEND_END_ARG_INFO();

and use my_func_arg_info as the arg_info parameter to the ZEND_FE() family
of macros.

The first arg to each ZEND_ARG_*() macro is whether or not to pass by ref.

The boolean arg to ZEND_BEGIN_ARG_INFO() tells the engine whether to treat
the arguments for which there's no explicit information as pass by reference
or not.
The boolean argument to ZEND_ARG_OBJ_INFO() (4th arg) is whether or not to allownull values.

d7e14ad8a3 Allow final private methods 
#
# Declaring a method private and final would only be an error for an abstract
# class. But at the moment the method is defined and it's modifiers are checked
# we do not know whether or not we have an abstract class. It could already be
# abstract but it also become abstract later.
#
# Since i made the mistake in first place i remove the check now.
#
# Providing the correct test would slow down the compiler becuase we'd have to
# iterate through all methods on all abstract classes and check for this. I
# guess we can live without. Or does anybody wants this to be implemented ?

0191ba5de1 allow expressions within constants, so the following is possible 
class foo {
	const a = 1<<0;
	const b = 1<<1;
	const c = a | b;
}

this makes const a compile-time expression.  all other operators are
unaffected.

 - The occurrence of class/interface/namespace definition is now

 - Functions/classes/interfaces/namespaces can be preceded by doc
   comments which are stored for use by extensions.

a4c3b2ce80 Namespace patch. Big changes: 
1. Nested classes are gone.
2. New syntax for namespaces:
namespace foo {
	class X { ... }
	function bar { ... }
	var x = 1;
	const ZZ = 2;
}
3. Namespaced symbol access: $x = new foo::X; - etc.
For now, namespaces are case insensitive, just like classes.
Also, there can be no global class and namespace with the same name
(to avoid ambiguities in :: resolution).

32b100e6cb - Allow variables to have both 'static' modifier and an access level. 
NOTE:  This only works at the syntax level right now (parser).  It
         doesn't actually work as of yet - all statics are considered
         public for now
- Prevent users from putting more restrictions on methods in derived classes
  (i.e., you cannot make a public method private in a derived class, etc.)

227f7838d6 - Fix build (thanks Marcus) 
- Implement abstract methods, syntax:
-    abstract function foo($vars);
- I don't see any reason why modifiers such as static/public need to be
- used with abstract. PHP is weakly typed and there would be no meaning to
- this anyway. People who want a strictly typed compiled language are
- looking in the wrong place.

830c2e0df6 fix statics - make it behave like $this (fetch type "static") 
Side effect: indirect references to statics won't work.

c497868005 - Add support for static methods. Basically methods which are defined as 
- static don't have $this. That's the whole difference.

f7f9721bdb - Change the automatically created variable $clone in __clone() to 
- $that as discussed at the PHP Conference. If there are any objections
- alternative names please let me know. The reason for changing it from
- $clone is because $clone sounds as if it's the newly cloned object and
- not the old one.

cf36abb2eb - Change opcode dispatch mechanism to use a function per opcode and use 
- a lookup table using the opcode # to call the correct function.
- Still have lots of tuning to do.

c42ec35331 Fix class static members: now the following code works: 
<?php

class Foo {
         static $c = "Parent";
}

class Child extends Foo {
}

Foo::$c = "Hello";

var_dump(Child::$c);
?>
and returns "Hello" (class statics are not copied anymore, but looked up in
runtime)

349b3a096a Fix and generalize $this handling. 
ZEND_FETCH_FROM_THIS is removed, IS_UNUSED type on class variables will be
used instead as the sign that it's a fetch from $this
