Followup for d74d3922ce
Attempting to require a file with (unset) casts results in an E_COMPILE_ERROR
that can't be caught or handled by set_exception_handler/set_error_handler.
Also remove the (bool) cast, because the ZEND_BOOL opcode handles that.
Remove inference that array -> object cast can throw.
It was added in 2a286ad599 - I don't know how creating an stdClass would throw.
(numeric keys, references, etc. don't cause it to throw)
Closes GH-5042
Internal constants can be marked as CONST_DEPRECATED, in which
case accessing them will throw a deprecation warning.
For now this is only supported on global constants, not class
constants. Complain to me if you need to deprecate a class
constant...
Closes GH-5072.
The op2 of FE_FETCH is only written if the loop edge is taken.
Fix up the SSA form to use the pre-assignment value if the exit
edge is taken.
This allows us to properly infer the type of the loop variable,
without letting the pre-loop type leak in.
Closes GH-5040.
This assumes that `iterator_*` will now always throw or abort on failure.
Also, move #include _arginfo.h directive to the top of the file - virtually all
other files put it there, and developers may base code on basic_functions.c.
Closes GH-4968
As far as I can determine, this is no longer a problem: We will
not try to remove the defining instructions (this is only done if
the value is known by SCCP itself) and we also only determine
non-refcounted values in this way, so it is not a problem if the
FREE is omitted.
See UPGRADING:
> . The GD extension now uses objects as the underlying data structure for
> images, rather than resources. These objects are completely opaque, i.e.
> they don't have any methods.
Remove types which are no longer in Reflection due to throwing instead of
emitting warnings.
Remove entries where reference counts are 0 and types are duplicated.
Closes GH-4967.
Remove functions such as filter_id() where reference counts and types are
identical to what's in opcache.
Remove null types from zend_func_info.c that aren't in Reflection
(php would throw now)
Fix the Reflection type information for assert_options()
php > assert_options(ASSERT_CALLBACK, static function() {});
php > var_export(assert_options(ASSERT_CALLBACK));
Closure::__set_state(array(
))
Closes GH-4958.
According to RFC: https://wiki.php.net/rfc/union_types_v2
The type representation now makes use of both the pointer payload
and the type mask at the same time. Additionall, zend_type_list is
introduced as a new kind of pointer payload, which is used to store
multiple class types. Each of the class types is a tagged pointer,
which may be either a class name or class entry. The latter is only
used for typed properties, while arguments/returns will instead use
cache slots. A type list can contain a mix of both names and CEs at
the same time, as not all classes may be resolvable.
One thing this is missing is support for union types in arginfo
and stubs, which I want to handle separately.
I've also dropped the special object code from the JIT implementation
for now -- I plan to add this back in a different form at a later time.
For now I did not want to include non-trivial JIT changes together
with large functional changes.
Another possible piece of follow-up work is to implement "iterable"
as an internal alias for "array|Traversable". I believe this will
eliminate quite a few special-cases that had to be implemented.
Closes GH-4838.
We now store the pointer payload and the type mask separately. This
is in preparation for union types, where we will be using both at
the same time.
To avoid increasing the size of arginfo structures, the
pass_by_reference and is_variadic fields are now stored as part of
the type_mask (8-bit are reserved for custom use).
Different types of pointer payloads are distinguished based on bits
in the type_mask.
