2d13dd0ef0 - Remove part of the cleanup which causes a problem with unnormal code 
like tests/lang/040.phpt
# However there is a memleak introduced somewhen after august 04 for such
# code now, 5.0 and 4.3 are fine though.

f916d603ef - Add arginfo ZEND_ARG_SEND_AUTOMATIC which lets the compiler automatically 
determine whether pass by ref is possible or pass by value is needed.
# This is usefull when functions take array or string parameters as
# expressions. In such a case force by ref is not applicable and the
# executor would copy the variable unnecessarily as soon as it is at least
# once referenced.

db507dd153 - Commit the variable fetch optimization. 
- Extensions which delete global variables need to use new special function
- delete_global_variable() (I'm about to rename it) to remove them.

96ab56e146 - Roll back VM commit 2004-09-09 16:47:22 +00:00
Andi Gutmans
8eb8850c90 - Some architectural changes: 
a) We specialize opcodes according to op_type fields. Each opcode has to
    be marked with which op_type's it uses.
 b) We support different execution methods. Function handlers, switch()
    and goto dispatching. goto seems to be the fastest but it really
    depends on the compiler and how well it optimizes. I suggest playing
    around with optimization flags.

- Warning: Things might break so keep us posted on how things are going.

e7e0f7d4b4 - Check return-by-reference bit when implementing interface prototypes 
- Add infrastructure for built-in functions to hint whether they
  return by reference or not.  It is NOT currently used for anything,
  except for interface prototypes (you can use it to request that the
  function that implements your prototype returns by reference or
  doesn't return by reference).
  For downwards compatibility - by default, interface prototypes are
  agnostic as to whether the function that implements them returns
  by reference or not.  Use ZEND_BEGIN_ARG_INFO_EX() with
  ZEND_RETURN_VALUE/ZEND_RETURN_REFERENCE to change that.
- Fix ArrayAccess::getOffset() to conduct additional checks.
  If your getOffset() should work with multidimensional arrays - it
  must return by reference.

c5d842279c Reinstate early-binding for classes. 
Note that this is available for downwards compatibility only - and it doesn't

loose (c)

9e60cb553f Rewrote exception support. Fixes a few limitations and bugs in the old 
implementation, and allows exceptions to 'fire' much earlier than before.

Instructions on how to use the new mechanism will follow on internals@
shortly...

set_exception_handler()

8e30d96ad8 Redesign the clone() feature to fix some fundamental flaws in the previous 
implementation.

Using clone directly is now done using
$replica = clone $src;

Clone methods must now be declared as follows:
function __clone($that)
{
}

Clone methods in derived classes can call the __clone method of their parent
classes using parent::__clone($that)

internal non-static methods statically.
# As discussed with Zeev:
# - For BC standard userspace methods allow this with an E_STRICT message.
# - If you want to implement an internal method taht can be called both
#   statically and non-statically then use flag ZEND_ACC_ALLOW_STATIC.
# - Magic user space methods __*() cannot and __construct, __destruct,
# __clone can never be called statically.

 2003-08-18 22:31:11 +00:00

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.

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

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

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).

03f88ac2b2 Add additional stage to post-session cleanup. 
We need separate cleanup stage because of the following problem:
Suppose we destroy class X, which destroys function table,
and in function table we have function foo() that has static $bar. Now if
object of class X was assigned to $bar, its destructor will be called and will
fail since X's function table is in mid-destruction.
So we want first of all to clean up all data and then move to tables
destruction.
Note that only run-time accessed data need to be cleaned up, pre-defined
data can not contain objects and thus are not probelmatic.
# Looks like we are having a lots of pain in the various parts of the body
# because of the destructors...

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.

__get/__set is called. If class has no method with given name, __call is called.
__get/__set are not recursive, __call can be.

e5015ed581 @ Fix problem with nested foreach()'s (Andi, Zend Engine) 2000-08-10 22:08:02 +00:00
Zeev Suraski
c06692e9ec The patch we promised - redesigned the compilation/execution API: 
Advantages:
- Smaller memory footprint for the op arrays
- Slightly faster compilation times (due to saved erealloc() calls and faster zend_op
  initialization)
- include_once() & require_once() share the same file list
- Consistency between include() and require() - this mostly means that return()
  works inside require()'d files just as it does in include() files (it used to
  be meaningless in require()'d files, most of the time (see below))
- Made require() consistent with itself.  Before, if the argument was not a constant
  string, require() took the include() behavior (with return()).
- Removed lots of duplicate code.
Bottom line - require() and include() are very similar now;  require() is simply an include()
which isn't allowed to fail.  Due to the erealloc() calls for large op arrays, require()
didn't end up being any faster than include() in the Zend engine.
