- 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.
- 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.
Note that this is available for downwards compatibility only - and it doesn't
work if you use new features (namely, interfaces). Generally, people should
declare their classes before using them, but we just didn't want hell to break
loose (c)
__clone() is back to not requiring any arguments, as $that is no longer
needed ($this already contains a copy of the original object, by the time
we __clone() is executed).
Calling the parent clone is done using parent::__clone()
implementation, and allows exceptions to 'fire' much earlier than before.
Instructions on how to use the new mechanism will follow on internals@
shortly...
Note - this (most probably) breaks the current implementation of
set_exception_handler()
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.
add E_STRICT warnings in case you return something by reference that you're
not supposed to (anything that's not a variable, or a return-value of a
function that returned by reference).
- Fix error in calculation of trace-string length
- Allow to overload __strostring() and make it work for uncaught exceptions
- Show exception thrown while displaying exceptions

while only interface_gets_implemented is the issue in this instance, both
these vars were unitialized, causing potential other issues

# There's only an errormessage missing which i'll wommit as soon as i find out
# how to do it best. But besides that damn message everything works now and all
# inheritance rules apply.
#
#
# The only known thing left at this moment is that the protected static members
# of a base class is different then the redeclared public property. I tried
# to remove both new and old static properties in the derived class and copy
# the base property with the new name. But for reasons i have to check later
# that didn't result in the expected behavior. Anyway we would need a warning
# if someone tries to change the value of a static property in a derived class.
#
- Use this to prevent memleaks when an exception gets thrown in ctors.
# I added the dtor flags for consistency, atm a compareable check in
# isn't necessary for destruction. But anyway i'll use this for the
# Relection API too.
this enables ZE2 to gracefully parse scripts written in UTF-8 (with BOM),
UTF-16, UTF-32, Shift_JIS, ISO-2022-JP etc... (when configured with
'--enable-zend-multibyte' and '--enable-mbstring')
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.
#
# 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 ?
