Fixes a bug introduced in 4008704f62
The trailing comma is followed by `)` when the varargs list
is empty in the macro, which is a syntax error in C
This fixes compilation of code such as the following
PHP_FUNCTION(get_metadata) {
if (zend_parse_parameters_throw(ZEND_NUM_ARGS(), "") == FAILURE) {
return;
}
Closes GH-4896.
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.
We have a number of "types" like integer which are not actually
supported as builtin types -- instead they are silently interpreted
as class types.
I've seen this cause confusion a few types already. This change adds
a warning in this case. In the unlikely case that someone legitimately
wants to type against an integer class, the warning can be suppressed
by writing \integer or "use integer", or using Integer (this warning
will only trigger for lowercase spellings).
Closes GH-4815.
* Change a number of "resource used as offset" notices to warnings,
which were previously missed.
* Throw the "resource used as offset" warning for isset() as well.
* Make array_key_exists() behavior with regard to different key
types consistent with isset() and normal array accesses. All key
types now use the usual coercions and array/object keys throw
TypeError.
Closes GH-4887.
